BACKGROUND OF THE INVENTION The present invention relates to a milling machine, a planing machine,
The present invention relates to vices used for machine tools such as drilling machines.

[0002]

2. Description of the Related Art A vise used in a conventional machine tool such as a milling machine includes a fixed body fixed to one end of a slide rail, a movable body slidably inserted in the slide rail, and a movable body. Fixed screws are respectively fixed to the end surfaces of the fixed body and the movable body which face each other, and the fixed bases are substantially 15 mm apart from each other.
It is equipped with a movable mouthpiece supported by an elastic body while becoming a swing at an inclination angle of degrees. Then, the fixed object is placed between these movable bases, the screw is rotated by the handle, and the movable body is moved to the fixed body side, so that the fixed object is firmly fixed to the vise, and the fixed object is fixed. I was doing cutting work.

However, in the above vise, when the movable body is moved by rotating the screw with the handle in order to obtain the stability of the fixed object in the vertical direction, the movable mouthpiece E slides as shown in FIG. , And sinks in the direction of arrow A (downward) and moves in the direction of arrow B (left lateral). Therefore,
In the vise, the position of the fixed object O, which is the object to be cut, is not constant, and when the fixed object O moves in the direction of arrow B in the case of cutting a groove or the like, the position of the fixed object O is not constant, The result is unusable.

Further, when the object to be fixed O is smaller than the diameter of the mouthpiece of the vise, the movable mouthpiece E is integrally formed by pinching it to either the right or left side of the mouthpiece and clamping and fixing it. As shown in (4), the movable mouthpiece E in the portion sandwiching the fixed object O is slid on the inclined surface and sinks because a force is applied. The movable mouthpiece E of the portion not sandwiching the fixed object O is
Since there is no object to be sandwiched, it does not slide on the inclined surface and the movable mouthpiece E in this portion does not sink, and the object to be fixed O is inclined and fixed to the mouthpiece as shown by the chain double-dashed line. Therefore, the fixed object O cannot be processed precisely. In addition, if the corners of the fixed object O are not taken accurately, it will not be parallel to the tightening end surface of the movable mouthpiece E, so it is necessary to use a spacer to stabilize and fix such fixed object O, which is difficult. In addition, when performing an angled work of the fixed object O, a separate device is required, which is expensive and the work is troublesome.

Under the circumstances, the applicant has provided a fixed side base on the end surface of the fixed body facing the movable body, and a plurality of fixed side independent claws supported by the elastic body protrude from the fixed side base. And a movable base is provided on an end surface of the movable body facing the fixed body, and the movable base is provided with a plurality of movable independent claws supported by an elastic body. (See Japanese Utility Model Publication No. 4-35093). And according to the vise of the applicant, the fixed object is placed between the fixed side independent claw of the fixed side base and the movable side independent claw of the movable side base, and the screw is rotated to fix the movable side base to the fixed side. When moved to the mouthpiece, only the fixed side and movable side independent claws that abut the fixed object sink against the projectile, and the fixed object sinks on average to the fixed side and movable side mouthpieces. It adheres to and is stably fixed both vertically and horizontally.

[0006]

SUMMARY OF THE INVENTION The vise of the applicant of the present invention improves the precision of the angle of the fixed object smaller than the point where the fixed object is stably fixed both vertically and horizontally and the diameter of the vise. Although it is excellent in terms of fixing, when increasing the angle of a wide fixed object close to the vise diameter with high accuracy, only one of the ferrules, that is, the fixed side or the movable side Since the adjusting device is provided, there is a risk that the angle cannot be accurately obtained unless the user is a cantilever and is not skilled.

Further, since the thin portions of the fixed and movable bases in the protruding portions of the fixed and movable independent claws are strongly fixed by hitting an object to be fixed, they are gradually deformed, and thereafter, both independent claws appear and disappear. It's gone.

Further, the contact surfaces of the fixed objects on the heads of the fixed and movable independent claws have a plurality of grooves to prevent them from slipping, but they wear due to use, making it difficult to fix the fixed objects. turn into.

Further, in order to provide the fixed side and movable side independent claws so that the fixed side and movable side independent claws can be projected and retracted, both round mouths are formed with circular holes, and both circular bar-shaped independent claws are inserted into these circular holes. It is best in processing to insert it. However, there is a possibility that the independent claw may rotate within the perfect hole. If this is not a perfect circle but an ellipse, an ellipse, or a corner, the independent claws will not turn, but the machining will be troublesome, and the accuracy will be difficult to obtain.

Further, the above-mentioned vise cannot handle a long object having a diameter larger than that of the vise at all, and a vise having a diameter suitable for the long object must be prepared separately. For this reason, although not frequently used, there have been inconveniences such as having to prepare vices having various diameters from a small diameter to a large diameter.

Therefore, the present invention has been made in view of the above circumstances in order to further increase the value of the vise by the present applicant. Even if the object to be fixed has a size substantially the same as the diameter of the vise, it is highly accurate. The angle can be set, and even if the object to be fixed is strongly fixed, each independent claw will always appear and disappear, and it can be fixed securely, and even one object can fix objects of various sizes, making it easy to manufacture. The challenge is to provide the vice.

Next, the operation of the vise 1 having the above configuration will be described.

First, the object to be fixed O is prepared, and the screw 9
The handle 10 is fitted into the prism 9a of FIG. 3 and the screw 9 is rotated by rotating the handle 10 to move the movable body 7 to the predetermined position in the right direction in FIGS. 1 to 3.

Next, a table commonly called "Yokan" is passed over the slide rails 4, the object to be fixed O prepared is placed on the table, and the handle 10 is rotated in the opposite direction to rotate the screw 9 in the opposite direction. The movable body 7 is rotated to the position shown in FIGS.
Move in the direction of the arrow H inside and tighten the fixed object O. At this time, first, the fixed side and movable side independent claws 13 and 19 inserted into the fixed side and movable side mouthpieces 6 and 8 are attached to the fixed object O.
However, since the non-slip plates 30 are slightly projected from the independent claws 13 and 19, the anti-slip plates 30 actually come into contact with the object O to be fixed. Further, the object to be fixed O is not slippery and has no mark on the fixed object O, and the surfaces 13a and 19a of the independent claws 13 and 19 are not worn. Figure 2
For fixed object O, four fixed and movable independent claws
13 and 19 will abut. Still, when the handle 10 is rotated, the four fixed side and movable side independent claws 13 and 19
Are submerged in the holes 6b and 8b against the spring force of the elastic springs 12 and 18, respectively, so that the object to be fixed O is sunk in the downward direction on average as shown in FIGS. As a result, the fixed object O comes into close contact with the base, and the non-slip plate 30 of the fixed side independent claw 13 and the non-slip plate 30 of the movable side independent claw 19 are fixed side and movable side bases 6 and 8 respectively. Until it is flush with the end faces 6a and 8a of the hole, the rotation stop mechanism C prevents the hole 6b from rotating.
And 8b. The fixed object O is brought into close contact with the non-slip plates 30 of the four fixed-side independent claws 13, the non-slip plate 30 of the movable-side independent claws 19, and the end surfaces 6a and 8a of the fixed-side and movable-side bases 6 and 8. Stable in the vertical and horizontal directions.

At this time, the end face 6a of the thin portion of the fixed side die 6
Since there are concave portions 32 in 8 and 8a, respectively, the fixed object O does not come into contact with these thin portions and is not deformed. Therefore, the fixed side and movable side independent claws 13 and 19 are always retracted in the holes 6b and 8b. it can.

Therefore, as in the conventional example shown in FIG. 22, the movable mouthpiece E sandwiching the object to be fixed O first sinks, and the movable mouthpiece E not sandwiched remains, resulting in the object O to be fixed. Does not tilt as shown by the chain double-dashed line in FIG.

Further, as in the conventional example shown in FIG. 21, the object to be fixed O is displaced vertically and horizontally depending on the occasion,
The fixed position does not become unstable. Further, the independent claw protrusion amount adjusting devices C and C ′ are necessary, for example, when the fixed object O having a shape as shown in FIGS. 14 and 15 is fixed by the fixed side and the movable side mouthpieces 6 and 8 of the vise 1. It will be. When the bolts 15 and 21 are moved upward, the locking plate
14 and 20, and the fixed side and movable side independent claws 13 and 19 are
It is pushed upward by the spring force of the elastic springs 12 and 18. Therefore, the fixed side and movable side independent claws 13 and
Since 19 protrudes from the holes 6b and 8b, the fixed side and movable side independent claws 13 and 19 have a large amount of protrusion.
The fixed object O having a shape as shown in 14 and 15 is stabilized in the vertical direction and the horizontal direction by the fixed side and movable side independent claws 13 and 19 and the end surfaces 6a and 8a of the fixed side and movable side caps 6 and 8, respectively. Can be fixed.

Further, the angle adjusting devices F and F'are used when the wide fixed object O is a rectangular parallelepiped or the like and the angle of the rectangular parallelepiped is cut, and its operation is as follows.
As shown in Fig. 16, the tightening bolt 17 (23) of the movable piece 16 (22)
The distance between the core and the protrusion 16b (22b) is L ₁ , and the protrusion 16b
If the radius of (22b) is L ₂ and the distance from the side T (T ') of the fixed and movable mouthpieces 6 and 8 to the outer circumference of the tightening bolt 17 (23) is L ₃ , the fixed side and Movable side base 6
And the protrusion 16b of the movable piece 16 (22) from the side T (T ') of 8
The distance L to the outer circumference of (22b) is expressed by equation (1).

L = L _{1 sin} θ + L ₃ −L ₂ (1) In equation (1), L ₁ , L ₂ , and L ₃ can be set in advance, and L can be easily measured with a caliper, etc. θ can be easily calculated. Therefore, if the angle θ is determined in advance and L is calculated, the tightening bolt 17 (23) is loosened and the movable piece 16 (22) is rotated so that the L dimension corresponds to the required angle θ. Then, by positioning and tightening the tightening bolt 17 (23), the movable piece 16 (22) inclined at the required angle θ can be obtained. For this reason, the fixed object O, which is the object to be cut having a rectangular parallelepiped corner to be cut on the inclined surface of the movable piece 16 (22).
Place the handle, turn the handle 10, and rotate the fixed side and movable side bases 6
By moving and tightening 8 and 8, the fixed object O can be stably held in the vertical direction and the horizontal direction with the required angle θ.
Can be fixed. Therefore, a simple operation is required to perform angle processing on a fixed object, and a device for angle processing is not particularly required.

Since the movable Z-shaped base 41 is exactly the same as the fixed Z-shaped base 40, the same reference numerals are given to the drawings and the description thereof will be omitted. Further, fixing the object to be fixed O using this vise 1a is substantially the same as that of the embodiment shown in FIGS. However, the embodiment of FIG. 17 cannot enjoy the advantages of the fixed side and movable side independent claws 13 and 19 of the vise 1 which are the embodiments of FIGS.
It is just an emergency evacuation advantage over the wide fixed object O, and there is no particular difference from the conventional vise.

FIGS. 18 to 20 show another embodiment of the present invention. This vise 1b is fixed to the fixed side and movable side caps 6 and 8 of the vise 1 which is the embodiment of FIGS. Also, the fixed side and movable side Z-shaped mouthpieces 50 and 51, which take advantage of the movable side independent claws 13 and 19, are detachably provided, and the fixed object is wider than the original diameter of the mouthpiece like the above-mentioned vise 1a.

[0043]

As described above in detail, according to the vise of the present invention, the distance corresponding to the required angle of the fixed object is determined, and both movable pieces are rotated by the distance to move the both. Match the distance between the projection of one piece and the fixed side of both movable pieces and the horizontal side end of the movable side mouthpiece, fix both movable pieces in this state, and place the fixed object on both movable pieces. When the screw is rotated and the movable side base is moved toward the fixed side base, only the fixed side and movable side independent claws sandwiching the fixed object first immerse against the projectile, and the The fixed object sinks on average and is closely fixed to the fixed side and movable side mouthpieces, and is stabilized vertically and horizontally. Therefore, even a fixed object having a width substantially the same as the diameter of the vise is placed over both movable pieces, so that the angle of the fixed object can be fixed with high accuracy.

Further, since the thin portions of the fixed-side and movable-side mouthpieces are provided with recesses, respectively, the thin-sided portions of the fixed-side and movable-side mouthpieces do not directly contact the object to be fixed by the recesses.

Further, when the fixed object is fixed by the fixed side and movable side caps, the fixed object is mainly fixed by the non-slip plate slightly protruding from the contact surface of the fixed side and movable side independent claws. The contact surface does not wear, so that the object to be fixed is securely fixed, and the anti-slip plate is replaced when it wears. Therefore, the object to be fixed can be reliably fixed at all times, and a highly accurate state can always be secured.

Further, the fixed side and movable side independent claws, which are formed into a cylindrical shape, do not rotate within the fixed side and movable side caps due to the rotation stopping mechanism. Therefore, the ellipse that is difficult to be machined on the surface side,
Since it is not necessary to form an ellipse or a corner, the processing cost can be remarkably reduced and an inexpensive vise can be provided.

Further, when the fixed side and movable side bases are provided with the fixed side and movable side Z-shaped bases, it is possible to fix a wide fixed object between the both Z-shaped bases.
Therefore, by preparing these fixed-side and movable-side Z-shaped mouthpieces having several kinds of diameters in advance, even one wide fixed object can be handled with one vise.

Further, if a plurality of fixed side and movable side independent claws supported by the elastic body are provided on the fixed side and movable side Z-shaped mouthpieces so as to be retractable and projecting, the fixed side is fixed similarly to the above. The object sinks on average and comes into close contact with the fixed-side and movable-side two-letters and is stably fixed both vertically and horizontally. Therefore, by preparing these fixed-side and movable-side Z-shaped mouthpieces having several kinds of diameters in advance, even if there is a wide object to be fixed, it has the advantage of the fixed-side and movable-side independent claws. Can be handled with one vise.
