Detailed Description of the Invention

[0001]

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 when it is clamped by being pinched to one of the left and right sides of the mouthpiece and fixed. As shown in FIG. 5, the movable mouthpiece E in the portion sandwiching the fixed object O is applied with force and slides on the inclined surface and sinks. The movable mouthpiece E in the portion not sandwiching the object to be fixed O does not slide on the inclined surface because there is no object to be sandwiched, and the movable mouthpiece E in this portion does not sink, and the object to be fixed O is shown by a two-dot chain line. It will be tilted and fixed to the base. 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]

The vise of the present applicant is excellent in that it stably fixes an object to be fixed both vertically and horizontally, but it is fixed at the protruding portions of the fixed and movable independent claws. Since the thin portions of the side and movable side caps are strongly fixed by hitting an object to be fixed, they are gradually deformed, and thereafter, both independent claws do not appear and disappear.

Further, the contact surfaces of the fixed object on the fixed side and movable side 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 object. 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 true circular holes, and both round bar-shaped independent claws are inserted into these true 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 vise cannot deal with a long object having a diameter larger than that of the vise, 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 utility value of the vise by the present applicant, and even if the object to be fixed is strongly fixed, the independent claws always appear and disappear. Moreover, it is an object of the present invention to provide a vise that can be securely fixed and can fix objects of various sizes with a single vise, and that is easy to manufacture.

However, since the configuration is exactly the same, detailed description thereof will be omitted. Further, the movable side cap and the independent claws 8 and 19 are also provided with the rotation stopping mechanism D for the same reason as the fixed side cap and the independent claws 6 and 13, but the structure is the same as the fixed side cap and the independent claws 6 and 13. Since it is the same, detailed description is omitted.

As described above, one end of the screw 9 is rotatably attached to the fixed body 5 and the other end of the screw 9 is rotatably attached to the slide rail 4. It is screwed by 7c. The portion of the screw 9 protruding from the slide rail 4 is the prism 9
The handle 10 is formed on the prism 9a.
Is removed. Therefore, the handle 10 is a prism 9 only when necessary.
It is fitted in a and is used to rotate the screw 9.

A swivel base 3 is mounted on the lower surface of the main body mounting portion 11 of the main body 2. The swivel base 3 is provided with a U-shaped groove 3a for mounting on a milling machine or the like.

Next, the operation of the vise 1 having the above structure will be described. First, the object to be fixed O is prepared, the handle 10 is fitted to the prism 9a of the screw 9, and the screw 9 is rotated by rotating the handle 10 to move the movable body 7 to a predetermined position in the right direction in FIGS. 1 to 3. Moving.

Next, a table commonly called "Yokan" is passed over the slide rail 4, the prepared object O is placed on the table, and the handle 9 is rotated in the reverse direction to rotate the screw 9 in the reverse 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 sunk 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 sinks in an average downward direction 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 base 6
Also, since the end face 8a of the thin portion of the movable side mouthpiece 8 has the recessed portions 32, the fixed object O does not abut against these thin portions and is not deformed. Therefore, the fixed side and movable side independent claws 13 and 19 are always holes. 6
The inside of b and the hole 8b can freely appear and disappear.

Therefore, as in the conventional example shown in FIG. 20, the movable mouthpiece E in the portion sandwiching the object to be fixed O is sunk first, and the movable mouthpiece E in the portion not sandwiched remains, and as a result, the object to be fixed O is held. Does not tilt as shown by the chain double-dashed line in FIG.

Further, as in the conventional example shown in FIG. 19, the object to be fixed O is displaced vertically and horizontally depending on the occasion,
The fixed position does not become unstable. In addition, 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. 12 and 13 is fixed by the fixed side of the vise 1 and the movable side mouthpieces 6 and 8. It will be. When the bolts 15, 15 and the bolts 21, 21 are moved upward, the locking plates 14 and 20, and the fixed side and movable side independent claws 13 and 19 are moved upward by that amount by the spring force of the elastic springs 12 and 18. Pushed up. Therefore, since the fixed side and movable side independent claws 13 and 19 project correspondingly from the holes 6b and 8b, the fixed side and movable side independent claws 13 and 19 have a large amount of projection, and therefore, as shown in FIGS. Fixed object O shaped as shown in
Can be stably fixed 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 mouthpieces 6 and 8.

The angle adjusting device F is used for cutting the corners of a rectangular parallelepiped, and its operation is as follows. As shown in Fig. 14, the tightening bolt 17 and the protrusion 16 of the movable piece 16 are
Let L _{1 be} the core-core distance from b, L ₂ be the radius of the protrusion 16 b, and L ₃ be the distance from the side T of the fixed side cap 6 to the outer circumference of the tightening bolt 17, and then the fixed side cap 6 The distance L from the side T to the outer circumference of the protrusion 16b of the movable piece 16 is expressed by the equation (1).

L = L _{1 sin} θ + L ₃ −L ₂ (1) In the equation (1), L ₁ , L ₂ , and L ₃ can be set in advance, and L can be easily measured with a caliper or the like. , The angle θ can be easily calculated. Therefore, if the angle θ is determined in advance and L is calculated, the tightening bolt 17 is loosened and the movable piece 16 is rotated and positioned so that the L dimension corresponds to the required angle θ. When the attached bolt 17 is tightened, the movable piece 16 tilted at the required angle θ can be obtained. Therefore, a fixed object O, which has a rectangular parallelepiped corner to be cut, is placed on the inclined surface of the movable piece 16, and the handle 10 is rotated to move and tighten the fixed side and movable side mouthpieces 6 and 8. For example, the object O can be fixed in a state where the required angle θ is stable in the vertical direction and the horizontal direction.

For this reason, when processing the angle of the fixed object,
In particular, angle processing can be performed by a simple operation without requiring a device for angle processing. FIG. 15 shows another embodiment of the present invention. This vise 1a is a fixed side and movable side Z-shaped member on the fixed side and movable side caps 6 and 8 of the vise 1 of the example shown in FIGS. The bases 40 and 41 are detachably provided so that a fixed object O having a width larger than the original diameter of the base can be fixed. That is, the side plates 42, 43 are provided on both sides of the fixed body 5.
Are attached with bolts 44 and 45, and both ends of the fixed side base 6 are extended by the thickness of the side plates 42 and 43.
42, 43 are attached with bolts 46, 47, and the above-mentioned fixed Z-shaped base 40 is firmly attached with bolts 48, 49 on the fixed side base 6 and side plates 42, 43. 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, the object to be fixed O is fixed by using this vise 1a as shown in FIG.
The description is omitted because it is substantially the same as that of the first to ninth embodiments. However, the embodiment of FIG. 15 is the vice 1 which is the embodiment of FIGS.
It is not possible to enjoy the advantages of the fixed side and movable side independent claws 13 and 19, and only the emergency evacuation advantage for the wide fixed object O is the same as the conventional vise.

FIGS. 16 to 18 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. O
It can be fixed. That is, the side plates 52 and 53 are attached to both side surfaces of the fixed body 5 with the bolts 54 and 55, and both ends of the fixed side cap 6 are extended by the thickness of the side plates 52 and 53, and the extended side portions also have the side plates 52 and 53. Attach with bolts 56 and 57,
The above-mentioned fixed-side Z-shaped base 50 is firmly attached onto the fixed-side base 6 and the side plates 52 and 53 with bolts 58 and 59. In FIGS. 16 and 17, reference numeral 60 is a bolt for adjusting the protruding amount of the independent claw. Further, the case of the movable side Z-shaped base 51 is exactly the same as the case of the fixed side Z-shaped base 50, so the same reference numerals are given to the drawings and the description thereof will be omitted. Further, fixing the wide object O to be fixed using this vise 1b is the same as in the embodiment shown in FIGS.

[0040]

As described above in detail, according to the vise of the present invention, the object to be fixed is placed between the fixed side independent claw of the fixed side mouthpiece and the movable side independent claw of the movable side mouthpiece, and the screw is attached. When the movable side mouthpiece is rotated and moved toward the fixed side mouthpiece, only the fixed side and movable side independent claws that are in contact with the fixed object first immerse against the projectile, and the fixed object averages. Of the fixed side and movable side mouthpieces, and the thin parts of the fixed side and movable side mouthpieces may directly hit the fixed object by the recesses. Since there is no load, it does not deform and does not deform. Therefore, the fixed-side and movable-side independent claws always appear and disappear freely to stably fix the object to be fixed both vertically and horizontally.

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 cylindrical fixed side and movable side independent claws 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 Z-shaped base and the movable side Z-shaped base are attached to the fixed side base and the movable side base,
A wide fixed object can be fixed between the two 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 an elastic body are provided on the fixed side and movable side Z-shaped mouthpieces so that they can project and retract, the same as the above case 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.
