Description

The present invention relates to a cleaner for machine tool parts that cleans machine parts such as a fitting hole for a spindle of a machine tool and a tool chucking hole (mounting hole) for a tool holder thereof.

Various tools are attached to the spindle of the machine tool via a tool holder. To attach the tool holder to the spindle or to the tool holder, insert the shank of the tool holder into the fitting hole of the spindle, or insert the shank of the tool into the tool chucking hole of the tool holder. conduct.
The BT shank type (MAS standard) shown in FIG. 8B is generally used as the shank fitting method, but in recent years, in order to improve the accuracy and rigidity when connecting the machine tool spindle and the tool holder. , A two-sided restraint method is adopted in which the joint portion is restrained by a tapered surface and a flange surface. This type of shank is called a hollow shank and is characterized by a hollow and short taper. For example, the HSK standard and the like correspond to this (see FIGS. 9 to 11).

Regardless of the shank type (standard), the inner surface of the fitting hole, the outer surface of the shank of the tool holder, and the tool chucking hole are cleaned regularly because cutting oil and cutting debris get in and adhere to them. There is a need to.
For this reason, various cleaners (cleaning tools) for cleaning cavities (holes) formed in various machine tool parts and the like have been conventionally proposed. For example, there is a case in which a grip portion and a rod-shaped cleaning portion connected to the tip of the grip portion are provided, and a cleaning body is provided in the direction of the outer peripheral surface length of the cleaning portion (Patent Document 1, Claims for Utility Model Registration, (See Fig. 1, Fig. 2, etc.).
This cleaner is fitted with the cleaning body by, for example, inserting the cleaning portion by holding the grip portion into the fitting hole of the spindle, rotating the grip portion around the shaft, and sliding the cleaning body against the inner surface of the fitting hole. Clean the inner surface of the hole.

In particular, the HSK cleaner coupling portion of the hollow taper shank standard like (fitting hole) is clamped components (e.g., Doroba D, collet reference C ₁ in FIG. 10 (b)) the fitting hole of the spindle while avoiding It is necessary to provide a cleaning portion that is thin and elastically contacts in order to clean the surface (see Patent Document 2, FIG. 1, FIG. 2, FIG. 3, etc.).
There is also a cleaner in which the cleaning body can be attached to and detached from the cleaning portion (see Patent Documents 3 and 1 to 5).

Real Fairness 3-57402 Gazette JP 2001-150290 U.S. Pat. No. 5,782,592

In the conventional cleaner, the cleaning body is made of chamois or the like, and the cleaning body is fixed to the outer surface of the rod-shaped cleaning portion by adhesive. In some cases, the cleaning body is fitted into the groove on the outer surface, but the fitting is positioning of the cleaning body on the outer peripheral surface of the cleaning portion, and the cleaning body is adhesively fixed in the groove (Patent Document). 1 Specification, page 2, column 3, lines 29 to 30, see FIG. 2).
The cleaning body is severely damaged and dirty and needs to be replaced frequently. However, as described above, conventionally, since the cleaning body such as chamois is fixed by adhesive or the like, it cannot be easily peeled off and its replacement is not easy.
The cleaner that makes the cleaning body removable has low mounting strength because the hooks at both ends of the cleaning body (see reference numerals 45 and 50 in FIG. 5 of Patent Document 3) are locked to the cleaning portion so that the cleaning body can be attached and detached. In some cases, it may come off during cleaning.

In particular, in the fitting hole of the main shaft, such as HSK standard, opening the inner diameter s of the tool holder _{T 3} There are those from about 14mm of the various magnitudes of 67 mm (see FIG. 10), the clamp parts to enter the inner diameter s (Drobar D, etc. in FIG. 10 (b) above) has the same outer diameter, so even if the hole is large enough to hold a finger, it will not fit when wiped by hand with a cloth or paper. Since the clamp part is located near the opening of the hole, it is difficult to clean it because fingers cannot enter it. Further, in order to clean the fitting hole of the spindle while avoiding the clamp component, it is necessary to provide a cleaning portion that is thin and elastically contacts (see Patent Document 2, FIG. 1, FIG. 2, FIG. 3 and the like).

It is an object of the present invention to ensure sufficient attachment strength of the cleaning body under the above-mentioned actual conditions, and to make it possible to easily attach / detach the cleaning body.

In order to solve the above problems, in the present invention, the rod-shaped cleaning body is fitted and attached to the groove having a narrow opening width of the cleaner body. After the rod-shaped cleaning body is fitted in the groove, it cannot be pulled out from the narrow opening and the mounting strength is high.
Specifically, in a cleaner for machine tool parts in which a cleaning body is slidably contacted along the peripheral surface of a cylindrical (including conical) surface to be cleaned, the cleaning body is the rod-shaped cleaner main body serving as a cleaning portion. It is attached to the cleaning surface facing the surface to be cleaned by fitting it into a groove in the axial direction, and the opening in the length direction of the groove is formed to be narrower than the inside.
Since the cleaning body is fitted into the groove, it has a rod shape, and the cleaning body is fitted into the groove by inserting the cleaning body into the groove through the end face opening of the groove, pushing the cleaning body through the narrow opening, or the like.
The "rod shape" referred to in the present invention includes not only a cylindrical hollow rod shape but also a solid (solid) rod shape.

The cleaner body may be a rod-shaped body having the same thickness, for example, a cylinder, a cylinder, a prism, a square cylinder, or a rod-shaped body having a conical or pyramidal tapered outer peripheral surface. Is the required length in the axial direction (see L in FIG. 3), and the thickness can be gradually increased from the same thickness portion toward the rear end. For example, the tip portion may have a columnar shape having the same diameter, and may have a conical columnar tapered surface whose diameter gradually increases from the columnar portion (the rear end of the required length portion) to the rear. The required axial length and taper angle (see θ in FIG. 1) are appropriately set by experiments or the like according to the shape and size of the surface to be cleaned so that the following wiping can be performed smoothly.
When the cross-sectional shape is other than circular, the required length in the axial direction "the same thickness" means that the outer peripheral surface (circumscribed surface, outer contact surface) drawn by each rod-shaped cleaning body on the outer peripheral surface of the cleaner body. a meaning diameter identical in r reference ₁₎ in FIG. 6 (a) (b), the term "gradually becomes thicker", toward the diameter rear side of the outer peripheral surface of the respective rod-like cleaning element is drawn It is meant to be a tapered surface that gradually increases.

In the above configuration, if the rod-shaped cleaning body is made of an elastic material, when the cleaning body is strongly pressed against the surface to be cleaned and rotated, the cleaning body contracts and the pressing pressure further adheres to the entire peripheral surface of the groove. Even if it is a rod-shaped cleaning body such as a columnar shape, it will not rotate in the groove, and the mounting strength will be higher, and it will be strongly pressed against the surface to be cleaned to ensure dirt. Catch it and peel it off. In addition, even if the surface to be cleaned has irregularities and the shape is distorted or the surface has slight dents, the cleaning body follows the distorted shape due to its elasticity, so cleaning can be performed. It will be done smoothly.
At this time, if the cleaning body is cylindrical (including cylindrical), the cleaning surface facing the cylindrical surface to be cleaned is substantially in line (shape). The elastic linear body per wire is more likely to fit the shape of the surface to be cleaned than the cleaning body per surface. Therefore, the cleaning effect is also high.
Further, if the cleaning body comes into contact with the surface to be cleaned, the space between the cleaning bodies is naturally widened (the space between the cleaning bodies can be sufficiently secured), and in the meantime, dirt such as peeled dust is removed. A large space for temporary storage can be secured. In addition, a large number of cleaning bodies can be installed on the cleaner body (on the circumference of the rotation). If many cleaning bodies are arranged on the circumference of the rotation, the entire surface can be cleaned even if the rotation angle is small, and the cleaning efficiency becomes high.

The rod-shaped elastic material may be cylindrical, cylindrical, prismatic, square-cylindrical, or the like, but if the cleaning body is tubular (hollow), the degree of deformation is large, so that the surface to be cleaned The fit to the shape is also improved, the cleaning effect is enhanced, and the expansion and contraction in the radial direction becomes easy, and it becomes easier to push the cleaning body of the elastic body into the groove. Further, since the cleaning body has a hole that opens on the end face, if a bar or the like is inserted into the hole on the end face and the cleaning body is pulled out from the groove through the bar, the cleaning body can be easily taken out from the groove. Can be done. The end face opening is not limited to a hollow cylindrical object, and even if it is a solid (solid) rod-shaped body, an insertion hole for a rod material or the like may be separately formed on the end surface thereof.

Here, if the surface to be cleaned consisting of the inner surface of the hole has a cylindrical shape having the same diameter over the entire length, a gap is usually generated between the inner surface of the hole and the outer surface of the cleaner body. Therefore, simply rotating the cleaner around its axis is sufficient. It may not be wiped clean. However, if the cleaning body is made of an elastic material, the cleaning body expands and contracts to follow the inner surface of the hole and have the same diameter, so the cleaner can be pushed into the hole, and if pushed in, it can be rotated and wiped clean. .. At this time, as described above, if the tip portion has the same thickness as the required length in the axial direction and gradually becomes thicker from the same thickness portion toward the rear end, for example, the cleaner A _{2 shown in FIG.} As described above, in the case where the tapered surface and the straight surface are continuous, the advantage of this action becomes remarkable.

Further, if the vertical cross-sectional area of the rod-shaped cleaning body made of an elastic material is increased with respect to the vertical cross-sectional area of the groove, the cleaning body contracts and is pushed into the groove when the cleaning body is fitted into the groove. Due to its own elasticity, it adheres to the entire peripheral surface of the groove and has sufficient mounting strength. That is, the vertical cross section of the groove has a circular shape with a notched opening, and the cleaning body also has a circular vertical cross section. And. For example, the ratio can be 0.85 ≦ d / r ≦ 0.97. If d / r is less than 0.8, it becomes difficult to push the cleaning body into the groove and workability deteriorates, while if it exceeds 0.97, the repulsive elasticity of the cleaning body fitted in the groove is not sufficient. Sufficient mounting strength may not be guaranteed.

In the cleaners for machine tool parts having each of the above configurations, in the case where the cylindrical cleaner to be cleaned has an end surface to be cleaned extending outward or inward, the end of the surface to be cleaned faces the end surface to be cleaned. It has a cleaning end face, and a rod-shaped cleaning body is fitted into the groove extending to the outside or inside of the cleaning end face, and the opening in the length direction of the groove is formed to be narrower than the inside. be able to.
In this way, not only the cylindrical surface to be cleaned such as a hole, but also the end surface to be cleaned extending to the outside or the inside can be cleaned at the time of cleaning.

Further, if an undulating piece is provided on the outer peripheral surface of the cleaner main body and a cleaning body is provided on the outer surface of the undulating piece, the inner surface of the hole having a size (diameter) according to the degree of undulation of the undulating piece can be cleaned. can. Therefore, even if a clamp component such as a collar F is near the opening of the hole (see FIG. 9), the clamp component can be avoided by the undulation of the undulating piece, and the hole can be cleaned.

If the cleaner body is composed of a rod-shaped cleaning portion and the gripping rod is detachably extended to the cleaning portion, the cleaning portion can be guided to a narrow place for cleaning by removing the gripping rod, for example. The cleaning work can be performed by turning the cleaning unit while pushing the rear surface with the palm.
If the gripping rod has a cylindrical shape, a spare cleaning body, other members, and the like can be stored inside the cylindrical shape. At this time, the opening of the storage space can be closed with a lid that can be screwed or screwed. In addition, magnets are built into the grip rods and lids, attached to them, hooks are provided, straps such as chains are provided, and cleaners are installed around the machine tool, its parts storage space, and work space. Easy means can be provided.

Since the present invention is configured as described above, sufficient attachment of the cleaning body can be ensured, and attachment / detachment of the cleaning body can be easily performed.

The operation of the embodiment shown in FIG. 1 is shown, (a) is a schematic cross-sectional view thereof, and (b) is a schematic cross-sectional view for explaining a cleaner object. FIG. 3 and FIG. 6 are cross-sectional views for explaining the operation of the embodiments shown in FIGS. The operation of the embodiment shown in FIG. 4 is shown, (a) is a schematic cross-sectional view thereof, and (b) is a schematic cross-sectional view for explaining a cleaner object. FIG. 5 is a cross-sectional view for explaining the operation of the embodiment shown in FIG. Partial perspective view showing a modification of the gripping rod of one embodiment of the cleaner according to the present invention.

An embodiment of the cleaner according to the present invention is shown in FIGS. 1 and 2, and the cleaner A ₁ of this embodiment (hereinafter _{, generic reference numeral: A including A 2 and the} like) is the spindle of the machining center shown in FIG. It cleans the tool holder fitting hole H and the like of the main spindle) M, and includes a truncated cone-shaped cleaner main body 10 and a gripping rod 20 connected to the rear end of the cleaner main body 10. The cleaner body 10 and the gripping rod 20 are made of metal or resin. The fitting hole H is usually in the shape of a truncated cone for centering.

The cleaner main body 10 has a hollow conical rod shape with a front opening 11c, and grooves 11 in the length direction (axial direction) are formed at equal intervals around the outer peripheral surface thereof. The degree of inclination of the outer peripheral surface to be the cleaning surface (tapering degree θ) may be appropriately set according to the degree of inclination of the inner surface of the hole to be cleaned, but it is the same as the degree of inclination of the truncated cone-shaped peripheral surface of the hole H. Can be the same.
The number of grooves 11 is arbitrary and does not necessarily have to be evenly spaced. In short, if the cleaning described later can be performed smoothly, the number and intervals thereof are appropriate, and may be appropriately determined by experiments or the like.
The groove 11 has a circular shape lacking a part of the vertical cross section (opening 11b). Therefore, a part opening 11a even in the distal end surface of the cleaner main body 10 is missing circular, with axial opening 11b of the outer peripheral surface is led to the outer peripheral surface entire length, width t ₁ of the opening 11b Is narrower than _{the diameter t 2} of the circular groove 11 _{(t 1} <t ₂ ). The degree of narrowness is appropriately set by an experiment or the like so that the following rod-shaped cleaning body 13 can be fitted into the groove 11 but does not come off by the degree of sliding. The groove 11 is formed by a drill or the like.

The cleaning body 13 is made of a cylindrical rod-shaped member made of porous plastic with olefin-based thermoplastic open cells, and is attached to the groove 11 by pushing and fitting as shown in FIG. At this time, since the cleaning body 13 is made of an elastic material made of a porous plastic, it is easily contracted and deformed, and its fitting is easy (see the solid line to the chain line in FIG. 1C). Further, since the bubbles are fine and the surface of the cleaning body is smooth, fitting is easy.
When the rod-shaped cleaning body 13 is fitted into the groove 11, as shown in FIG. 1 (b), the cleaning body 13 enters the groove 11 without a gap, and the opening width t ₁ of the groove 11 becomes narrower than the diameter t _2. Therefore, the cleaning body 13 does not easily come out. Therefore, even the cylindrical cleaning body 13 does not rotate in the groove 11, and the mounting strength is high.
The material of the cleaning body 13 is not limited to the porous plastic of thermoplastic open cells, and any elastic body that can be used as a rod-shaped cleaning body may be used. Further, the shape is not limited to a cylinder, and may be a square cylinder, a solid (solid) cylinder, or a prism. At this time, if the cylinder is hollow, it is more easily contracted and deformed, which is a preferable mode such that the fitting into the groove and the pressing force at the time of cleaning can be further obtained.

The rear portion of the cleaner main body 10 is a rod-shaped grip portion 14, and the surface thereof is knurled 15 such as twill to prevent slipping. The length (axial direction) of the grip portion 14 is such that the rear surface thereof can be brought into contact with the palm to grip the outer peripheral surface.
The grip rod 20 can be inserted into the cylindrical grip portion 14 of the cleaner main body 10, and is integrated with the cleaner main body 10 by screwing the mounting screw 17 into the screw hole 27 from the hole 16 of the grip portion 14. The gripping rod 20 is also knurled 25 to prevent slipping.

This cleaner A _1, for example, shown in FIG. 8 (b), In the tool holder T ₁ spindle M of BT shank, as shown in FIG. 6 (a), similarly to the conventional frustoconical cleaning by rotating its axis around insert the cleaner a ₁ into the hole H. At this time, since there is usually a large space in front of the main shaft M, the gripping rod 20 is attached in the mounted state (chain line state in the figure). In the figure, D is Doroba, C is a gripping collet of Doroba D tip Purusutatto P of the tool holder T ₁ of the.
When cleaning holes in a tool holder storage pot such as a machining center, the work is often performed in a narrow space. Therefore, as shown by the solid line in FIG. 8A, the gripping rod 20 is removed for cleaning. In this case, the rear surface of the grip portion 14 is placed against the palm to grip the outer peripheral surface for cleaning.
Different inclination degree of the frustoconical circumferential surface of the inclined degree (see θ in Fig. 1) and the hole H of the cleaner main body 10 of the cleaner A _1, hole cleaner A ₁ rotates like inclined relative to the axis of the hole H The cleaning body 13 is slidably contacted over the entire inner peripheral surface of H to remove dirt from the entire area.

When the cleaning body 13 is replaced due to wear or the like, the replacement is performed, for example, by inserting the rod 30 into the central hole 13a of the cleaning body 13 and lifting it as shown by the chain line in FIG. When the cleaning body 13 is removed from the groove 11, a new cleaning body 13 is fitted into the groove 11. As shown in the drawing, if the two rods 30 are integrated, the two cleaning bodies 13 and 13 can be removed at the same time. The cleaning body 13 may be a solid elastic body having no central hole 13a.

The shape of the cleaner main body 10 is not limited to the above embodiment, and may be appropriately determined according to the shape and size of the surface to be cleaned. For example, as shown in FIG. 3, the shape of the grip portion 14 is changed, and as shown in FIG. 4, the tapered tubular portion and the flange portion 10a at the edge thereof corresponding to the HSK shank (hollow taper shank) are cleaned. It may be a hollow cleaner body 10 having a surface. At this time, the cleaning body 13 is fitted and attached to the _{groove 11 having the same shape (t 1} <t ₂ ) as the groove 11 on the surface (side surface) of the flange portion 10a.

_{In the cleaner A 2} of the embodiment shown in FIG. 3, since the tip of the cleaner main body 10 has a cylindrical shape having the same diameter, for example, as shown in FIG. 9, the tool holder T _{2 has} the same shape tool mounting hole H. Clean the inner peripheral surface by fitting it into a cylinder.
In the case of the cleaner A ₂ , if the surface to be cleaned (inner surface of the fitting hole H) is cylindrical with the same diameter over the entire length _{, a gap is usually generated between the inner surface of the hole and the outer surface of the cleaner A 2,} so that the cleaner A ₂ There is a risk that it cannot be wiped clean just by rotating it around its axis. However, if the cleaning body 13 has a cylindrical shape made of an elastic material, the cleaning body 13 _{expands and contracts to have the same diameter as the inner surface of the hole, so that the cleaner A 2} can be pushed into the hole, and if pushed in, it rotates. It can be wiped clean. In particular, as the cleaner A ₂ shown in FIG. 3, the apparatus having the tapered surface and the straight surface is continuous, advantage of this effect becomes remarkable.

Cleaner A ₃ of the embodiment shown in FIG. 4, for example, shown in FIG. 10 (b), In the tool holder T ₃ spindle M of HSK shank, as shown in FIG. 6 (a), similarly to the conventional , cleaned by rotating insert the cleaner a ₃ into the hole H. In the figure, C ₁ is an HSK collet of _{the tool holder T 3} at the tip of the drawer D.
Usually, when cleaning both sides of the fitting hole H having two surfaces, the tapered surface and the end surface, as shown in FIG. 10, by a cleaner having a cleaning surface on the tapered tubular portion and the flange portion 10a, the taper is used. When the cleaning surface of the tubular portion hits the tapered surface of the fitting hole H, a gap is likely to occur between the cleaning surface of the flange portion 10a and the end surface of the fitting hole H. At this time, if the pulling force is due to a mechanical mechanism such as a drawer (for example, 5700 N), the tubular portion corresponding to the tapered surface is deformed or the collar portion is deformed to fit the cleaning surface of the collar portion 10a. It can be applied to the end face of the hole H, but since this type of cleaning is done manually, the cleaner is not easy to deform and is almost impossible. That is, the cleaner main body 10 and the like cannot be deformed by manual force, and the cleaning surface cannot be strongly applied to both sides. However, the cleaning element 13 of the cleaner A ₃ is for a hollow cylindrical shape made of an elastic material, easily obtained much the amount of deformation. Therefore, with respect to both surfaces of the fitting hole H having two surfaces, a tapered surface and an end surface, the tapered surface is a truncated cone-shaped outer surface (tapered surface) of the cleaner main body 10, and the end surface is an end surface rising from the outer edge. Each cleaning body 13 (side surface of the flange portion 10a) comes into contact with each other, and at the same time, it can be strongly applied for cleaning. The amount of protrusion of each cleaning body 13 from the mounting surface (outer surface of the tapered tubular portion and the side surface of the flange portion) strongly abuts on the tapered surface and the end surface at the same time according to the inclination of the tapered surface due to the reduced diameter of the elastic cleaning body 13. Set appropriately to obtain.

Further, as shown in FIG. 5, if the cleaner A ₄ were fitted fit the cleaning element 13 in the groove 11 of the inner peripheral surface and the end surface of the bottomed cylindrical cleaner main body 10, for example, shown in Figure 11, the HSK shank tool it is possible to clean the outer peripheral surface thereof by rotating is fitted to the shank peripheral surface of the holder T _3. Also in this case, since the cleaning body 13 has a hollow cylindrical shape made of an elastic material, the amount of deformation thereof is increased, and both sides of the fitting hole H having two surfaces, a tapered surface and an end surface, are strongly pressed at the same time for cleaning. can do.

Further, as an aspect of the cleaner main body 10, as shown in FIG. 6, the cross section is triangular, the cleaning body 13 is fitted and attached to the groove 11 of each ridge thereof, and the undulating piece 19 is provided on the flat surface portion. The cleaning body 13 may be provided on the outer surface of the undulating piece 19 _{via a groove 11 having the same shape (t 1} <t ₂ ) as the groove 11.
The undulating piece 19 is provided with a base portion 19a automatically rotated in the radial direction via a pin 19b, and can swing outward in the radial direction by a spring (not shown). It is also possible to make it possible to stand outward in the radial direction by the elasticity of the undulating piece 19 itself without providing the pin 19b.

Cleaner A ₅ in this embodiment, for example, as shown in FIG. 9, the HSK standard for the tool holder T ₂ shank such flange F protruding inwardly into the opening of the hole H as (HSK shank) If there is a convex portion, the undulating piece 19 is laid down like a chain wire and inserted into the hole H, and then the undulating piece 19 is erected and the cleaning body 13 of the undulating piece 19 is slid on the inner surface of the hole H for cleaning. do. The cleaner A ₅ can clean the entire inner peripheral surface of the hole H. At this time, the presence of the flange F and coolant ducts G, even when the do not fall finger into the hole H, the undulations of the undulating strips 19, cleaner A ₅ are fitted to the entire inner peripheral surface of the hole H thereof The entire inner peripheral surface can be cleaned. That is, even if the inner diameter of the shank fitting hole H is about 14 mm, if the outer diameter of the undulating piece 19 at the time of lodging is large enough to pass through the collar F, the entire inner peripheral surface of the hole H should be cleaned. Can be done.

In the above embodiment, the outer diameter r of the columnar cleaning body 13 is 5 mm, the vertical cross-sectional diameter of the groove 11 is 4.7 mm (d / r = 0.94), r: 3 mm, and d: 2.7. (D / r = 0.9), r: 2 mm, d / 1.8 (d / r = 0.9) were prototyped, and each groove was shown in FIG. 1 (c). When the cleaning body 13 was fitted into the cleaning body 13 and a cleaning test was performed on the cleaner body 10 having an appropriate thickness (diameter) and an appropriate size of the surface to be cleaned, the cleaning body 13 of the elastic body was firmly formed on the entire inner circumference of the groove 11. Smooth cleaning was possible without sticking and popping out (pulling out).

Various structures can be adopted for the connection between the cleaner body 10 and the gripping rod 20 as long as they are removable. For example, as shown in FIG. 7, the bolt 21 of the gripping rod 20 is screwed into the female screw hole 14a of the cleaner main body 10 to connect the two 10 and 20. At this time, it is preferable that at least one of the facing surfaces of the cleaner main body 10 and the gripping rod 20 is knurled (streaked) 15a with uneven stripes in the radial direction. This knurling 15a can be formed on at least one of the surfaces of the grip portion 14 facing the grip rod 20 in the cleaner main body 10 of each of the other embodiments. In FIG. 7, knurling 15a was applied to the facing surface of the gripping rod 20.
Further, as shown in FIG. 12, if the gripping rod 20 has a cylindrical shape, a spare rod-shaped cleaning body 13 and various other members can be stored inside the cylindrical shape. The opening of the storage space 20a is preferably closed by a lid 28 that can be screwed or screwed. Further, a magnet M is built in or attached to the gripping rod 20 and the lid 28, a hook is provided, a strap 29 such as a chain is provided, etc. Make it easier to install cleaner A (A _{1 to} A _5).

From the above, according to the present invention, even in a hole having a complicated structure such as an HSK standard spindle M or a tool holder shank, the elastic cleaning body 13 firmly adheres to the entire inner circumference of the groove 11 and pops out. It can be understood that the cleaning body 13 can be easily attached and detached as well as being able to be cleaned without any problem.
Further, if the cleaning body 13 can be easily attached and detached, in each of the above embodiments, the shape of the groove 11 is not limited to a circular cross section, and the opening 11a of the groove 11 becomes narrower to form the groove 11. As long as the fitted cleaning body 13 does not come out (does not pop out), a polygon such as a square or a dovetail shape may be used. Further, the shape of the cleaner main body 10 can be appropriately changed according to the object to be cleaned, and the cross-sectional shape thereof is not limited to a circle or a triangle, but may be another polygon such as an ellipse or a square. .. In the case of a polygon, a regular polygon is preferable.
Further, the cleaning body 13 is not limited to the cylindrical bar material, and in each of the above embodiments (A _{1 to} A ₅ ), the cleaning body 13 has a cylindrical shape, a square cylinder shape, a prismatic shape, or the like and a shape that can be fitted into the groove 11 and prevented from coming off. If so, it goes without saying that it can be appropriately selected.

Each of the cleaners A (A _{1 to} A ₅ ) includes holes and outer circumferences of various machine tool parts such as the inner and outer peripheral surfaces of various tool holders such as BT shanks that require cleaning as well as the main shafts M and HSK shanks. It goes without saying that it can be used for cleaning the surface.
Thus, the embodiments disclosed this time should be considered to be exemplary in all respects and not restrictive. The scope of the present invention is indicated by the claims and is intended to include all modifications within the meaning and scope equivalent to the claims.

The mode in which the undulating piece 19 having the cleaning body 13 is provided on the outer peripheral surface of the cleaner main body 10 shown in FIG. 6 is various conventional modes such as a cleaner in which the cleaning body 13 is adhered and fixed, regardless of the invention according to the present application. Can be adapted to the cleaner of the above aspect.
