Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a jig used for clamping a workpiece in a vise attached to various machine tools or in a single vise.

[Conventional technology]

When mounting a workpiece in a vise for shaping, flat sliding, vertical cutting, etc., if the clamping surface of the workpiece is parallel to the jaws of the vise, it will be directly held by both jaws without any problem, but the workpiece If the clamping surface is sloped or uneven, the holding condition will become unstable.
The workpiece tilts during cutting and cannot be finished at right angles or parallel. In such cases, conventionally, a round bar or the like is interposed between the jaws of the work and the vice to hold it.

[Problem to be solved by the invention]

If the above-mentioned round rod is used to sandwich the rod, there will be point contact (line contact in the longitudinal direction of the rod), and if both contact points are symmetrical about the center point of the circle of the round rod, then Although this is not as much of a problem as the difference, there are many cases in which they come into contact at a position that is deviated from the symmetrical position, and in such cases, the clamping becomes unstable.

The object of the present invention is to solve the above-mentioned problems, and to provide a jig that can securely disperse and hold a workpiece without concentrating the tightening force of a vise in one place.

[Means to solve the problem]

The solution according to the present invention is that one side edge of the plate is formed as a straight edge, and the other side edge opposite to the straight edge is formed as a convexly curved arc edge, and either the straight edge or the circular arc edge is formed. Formed into a curved surface with one edge surface convexly curved,
It is characterized in that the other edge surface is formed as an upright surface that is perpendicular to both the front and back surfaces of the plate.

[Effect]

When holding a workpiece using the above jig,
It is attached with an arcuate edge or a straight edge interposed toward the jaw side of the vise or toward the workpiece side.

〔Example〕

To specifically explain the present invention, FIGS. 1 and 2 show a first embodiment, which is made up of a metal plate 1, and when viewed from above, one side edge of the plate 1 is a straight edge 2. The other side edge opposite to the straight edge 2 is formed into a convex arcuate edge 3, and the edge surface of the straight edge 2 is formed into an upright surface that is perpendicular to both the front and back surfaces of the plate 1. On the other hand, the edge surface of the arc edge 3 is formed into a convex curved surface.

In the second embodiment shown in FIGS. 3 and 4, the opposite side edges of the plate 1 are formed into a straight edge 2 and a circular arc edge 3, as in the previous example, and the difference is that the straight edge The edge surface 2 is formed into a convex curved surface, and the edge surface on the side of the arcuate edge 3 is formed into an upright surface.

The third embodiment shown in FIGS. 5 and 6 has a straight edge 2
One surface of the plate 1 is shaved to form an inclined surface 4 that becomes lower toward the edge, and an upright surface 5 is provided at the tip of the inclined surface 4.The other structure is the same as that of the previous example.

In addition to the structure of the first embodiment shown in FIGS. 1 and 2, the fourth embodiment shown in FIGS. It is provided by being formed on a surface.

Because of the above structure, it is used when the surface of the workpiece 9 held in the vise that faces the jaws 7 and 8 of the vise is sloped or has an uneven surface, as shown in Figures 9 onwards. The 9th
If the work 9 is inclined in the height direction like a trapezoid as shown in the figure, set the straight edge 2 toward the jaws 7 and 8 and the arcuate edge 3 toward the work 9 and tighten. Good, if it is the one of the first embodiment, the 10th
As shown in the figure, since the straight edge 2 serves as an upright surface, the straight edge 2 is attached toward the jaws 7 and 8 side. Further, in the case of the second embodiment, as shown in FIG. 11, the arcuate edge 3 forming the upright surface is attached toward the jaws 7 and 8 side.

If the workpiece 9 is inclined in the width direction, in the case of the first embodiment, as shown in FIGS. 12 and 13, and in the case of the second embodiment, as shown in FIG. In both cases, the straight edge 2 is directed toward the workpiece 9.

If the clamping surface of the workpiece 9 is uneven, the first
Alternatively, the second embodiment may be used, and the straight edge 2 may be attached to the workpiece 9 as shown in FIG.

In the third embodiment, as shown in FIG. 16, the inclined straight edge 2 is attached toward the workpiece 9, and the workpiece 9 is tightened while being pressed downward.

If the workpiece 9 has a circular cross section or a convex curved part, the workpiece 9 of the fourth embodiment is used to cut the V-shaped notch 6 as shown in FIGS. 17 and 18. It clamps and tightens the curved portion of the workpiece 9.

〔Effect of the invention〕

By using the vise jig according to the present invention, the straight edge, the arc edge, and each edge surface are formed into an upright surface and a curved surface. Even if it is a workpiece, the entire surface of the upright surface comes into contact with the jaw or workpiece, and the curved surface comes into contact with a dot or line, but because of the upright surface, a large clamping force can be applied, and moreover, both jaws of the vise can Since the clamping force is maintained parallel to the direction of action of the tightening force, the clamping force against the workpiece is increased.
It can be installed in an extremely stable condition.
