Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to improving the operability of a vise.

[Prior art] The front part is a threaded part with a guide thread formed on the outer periphery, and the rear part is a shaft that is a round bar-shaped base, and a fixed position member that is fitted to the base of the shaft so that it can freely rotate. ,
A movable member is screwed onto the guide screw and supported so as to be movable back and forth along the axial direction of the threaded portion by rotation of the shaft, and the movable member is provided on opposing surfaces of the fixed position member and the movable member, respectively. There is a vise that clamps objects with its clamping surfaces.

[Problems to be solved by the invention] However, in the conventional vise described above, when moving a movable member to a predetermined position according to the thickness of the material to be fixed, the shaft must be rotated by an amount corresponding to the amount of movement of the member. Since it had to be fixed, there was a problem that the fixing work was troublesome and time consuming.

[Means for Solving the Problems] In order to solve the above problems, the present invention has the following configuration. That is, the vise according to the present invention has a threaded part with a guide thread formed on the outer periphery at the front part, and a shaft which is a round bar-shaped base at the rear part, and is fitted into the base of the shaft so as to be freely rotatable. A vice comprising a fixed position member and a movable member screwed onto the guide screw and supported so as to be movable back and forth along the axial direction of the threaded portion by rotation of the shaft,
The movable member has an axial center slightly inclined with respect to the screw hole at the same position as the screw hole into which the guide screw of the shaft is screwed,
Moreover, it is characterized by providing an inclined hole having a diameter larger than the outer diameter of the guide screw.

[Function] An inclined hole is provided at the same position as the screw hole of the movable member, the axis of which is slightly inclined with respect to the screw hole, and whose diameter is larger than the outer diameter of the guide screw. If the movable member is inclined with respect to the axis so that its center faces in the same direction as the axis of the guide screw, the movable member can be quickly moved back and forth along the axis.

If the movable member is maintained in a predetermined position relative to the axis so that the axis of the movable member matches the axis of the guide screw,
The screw hole of the movable member and the guide screw of the shaft are screwed together, so by rotating the shaft in this state, the movable member moves back and forth along the threaded part of the shaft, and moves with the clamping surface of the fixed position member. The material to be fixed is reliably held between the holding surfaces of the members.

[Embodiment] FIG. 1 and subsequent figures show a corner vise as an embodiment of the vice according to the present invention, and this corner vise 1 includes a shaft 3, a fixed position member 4, and a moving member 5.

The shaft 3 consists of a smooth round bar-shaped base 3a and a threaded part 3b having a guide screw 7 formed on its outer periphery, and a grip 8 is integrally attached to the rear end of the base 3a.

The positional member 4 has a base 11 with a flat surface 10.
Clamping portions 12, 12 are provided at both ends of the base at an angle of 45° in the forward direction with respect to the base. In addition, the base 1
A triangular small clamp holder 13 is provided at the rear end of the holder 1 to protrude upward. Respective clamping surfaces 12a, 12b, 1 of these clamping parts 12 and small clamping parts 13
3a are both perpendicular to the plane 10, and 12
a and 12b are formed at right angles to each other, and 12b and 13a are formed parallel to each other. Further, a clamping surface 12a of one clamping part 12 and a clamping surface 13a of the small clamping part 13 on the opposite side to the clamping part are provided on the same plane. A locking projection 14 whose upper surface is formed at the same height as the flat surface 10 is provided at the front end of the clamping portion 12 .

The fixed position member 4 has a rectangular through hole 16 that communicates from front to back in the base 11, and a spacer 17 that is rotatably attached around the axis of the round bar-shaped base 3a of the shaft 3 is fitted into this through hole 16. has been done. The intermediate material 17 has circular holes 20, 20' provided with standing edges 19, 19' around the base of the upper and lower surfaces thereof, and circular protrusions 22, 22' of the fixed position members are inserted into these holes. . Therefore, the spacer 17 is supported rotatably within a horizontal plane around the circular protrusions 22, 22'. Since the annular protrusion 24 of the spacer 17 is engaged with the annular groove 23 of the base 3a, the spacer 17 is prevented from shifting in the axial direction of the shaft 3. In addition, through hole 16
The width becomes wider as it goes from the base to the opening, and at the rotation limit position of the spacer 17, the width becomes wider from the base to the opening.
and the side wall of the through hole 16 are configured so as to be in contact with each other in a plane.

The movable member 5 has a triangular rear portion at its upper portion that is a clamping portion 25 that protrudes rearward, and both side surfaces thereof are clamping surfaces 25a, 25a. These clamping surfaces 25
a and 25d are at right angles to each other. Clamping part 2
5 is provided with a locking protrusion 26 formed at the same height as the plane 10 of the fixed position member 4 when the movable member 5 is at the same position as the fixed position member 4 around the axis 3. . Similar to the fixed position member 4, the movable member 5 is also provided with a rectangular through hole 28 that communicates from front to back, and a spacer 30 is fitted into this through hole 28. The spacer 30 is rotatably supported in a horizontal plane around the circular protrusions 32, 32'. As shown in FIG. 4, the intermediate material 30 is horizontally provided with a guide screw hole 34 into which the guide screw 7 of the shaft 3 is screwed, and a guide screw hole 34 is provided at the same position as the guide screw hole 34. A smooth inclined hole 35 with a slightly larger diameter than
is provided to be inclined at an angle θ with respect to the guide screw hole 34. The base of the screw hole 34 is the inclined hole 3
5, a portion of the thread groove 36 is exposed at the front upper part and rear lower part of the screw hole 34. In the illustrated example, the inclined holes are provided such that the positions are higher toward the rear, but it is also possible to provide the inclined holes which are located higher toward the front. The angle θ is preferably about 10 to 20 degrees, but is not limited to this.

Next, a case will be described in which two rod-shaped frame members are fixed in a T-shape as members to be fixed using this corner vise 1. First, as shown in FIGS. 5 and 6, the movable member 5 is moved rearward with its rear part facing downward with respect to the shaft 3, and the fixed member 4 and the movable member 5 are Make sure the spacing is appropriate. By tilting the movable member 5 when moving the movable member 5, the threaded portion 3b of the shaft and the inclined hole 35 become parallel, and the guide screw 7
Since the screw groove 36 and the screw groove 36 are no longer screwed together, the movable member 5 can be freely and quickly slid along the screw portion 3b. Next, frame members 41 and 4 are placed between the fixed member 4 and the movable member 5 in the space 40 and 40'.
2 and turn grip 8 clockwise (arrow X direction)
Rotate it. The shaft 3 freely rotates with respect to the fixed position member 4, but with respect to the movable member 5, the guide screw 7 is screwed into the thread groove 36 of the intermediate material 30, so that the movable member 5 is retracted as a result, Spacing part 40, 4
Narrow the width of 0'. When the grip 8 is further rotated, the two members 4 and 5 approach each other until finally, as shown in FIG.
Fix 2 firmly. That is, by tightening the grip 8, the frame member 41 is moved between the gripping surfaces 12aA and 25aA, and the frame member 42 is moved between the gripping surfaces 12aB and 25aA.
5aB and are held in close contact with each other.
Therefore, the frame members 41 and 42 are fixed while maintaining an angle of exactly 90°. Since the fixed position member 4 and the movable member 5 rotate appropriately with respect to the shaft 3 in an oscillating manner, they have high adhesion to the frame members 41 and 42, and due to this rotation, the spacing parts 40 and 40' are Since the width can be adjusted, even if a set of frame members have different thicknesses, they can be fixed in good condition. Furthermore, the fixing operation is extremely simple, as all you have to do is rotate the grip. Further, since the vice 1 can move the moving member 5 to an appropriate position while sliding it along the shaft 3, the work can be carried out quickly. When removing the fixed frame material, move the grip 8 in the opposite direction (counter to the direction of the arrow X).
Just rotate it.

In the above description, the case where the frame members 41 and 42 are fixed in a T-shape has been described, but it is also possible to fix them in an L-shape, or to stack the frame members 41 and 42 on different levels and fix them in a cross shape.

In the embodiment, a corner vise for fixing two objects to be held at an angle of 90 degrees has been described, but it is possible to fix them at an angle other than 90 degrees by changing the angle of the holding surfaces. It goes without saying that the present invention can also be applied to ordinary flat vises and other vises.

[Effects of the invention] As is clear from the above explanation, the vise according to the invention can slide along the axis simply by tilting the movable member that tightens the object using the threaded relationship with the axis. However, it can be moved freely and quickly, improving work efficiency when fixing objects.
