Description

[Detailed Description of the Invention] This invention relates to an improvement of a workbench jig used by workers on the side of a conveyor line, etc.

A conventional workbench jig is shown in FIG.

Reference numeral 1 denotes a workbench base, 2 a support means fixed to the base 1 with screws 3 and having a support end formed into a single-shaped groove, and 4 a workpiece.

In the conventional workbench jig, in order to make the support means 2 movable in the horizontal direction in response to work objects 4 of different sizes,
Although the elongated hole 5 is formed in the base 1, there is a drawback that the cost required for machining the elongated hole 5 is high.

In addition, since the support means 2 is rectangular, it has drawbacks such as being apt to become an obstacle during work.

This invention was made in view of this point, and one embodiment will be described below.

6 is the workbench base, 7 is the work object, 8 is the work object 7
It is a cylindrical support means that supports the base 6 and is fixed to the base 6 with screws 9.

Since the support means 8 is fixed with a screw 9 at its axial center, it is rotatable about the axial center.

However, the support means 8 does not rotate easily because there is a moderate frictional force between the screw 9 and the base 6.

The support means 8 has a locking protrusion 10 erected on the support end face eccentrically with respect to the axis.

In the support means 8, when the locking protrusion 10 is horizontally moved in accordance with the size of the workpiece 7, the support means 8 is rotated about the axis.

The value X of the movement adjustment width of the locking projection 10 can be up to twice the value Y of the eccentricity width of the locking projection 10.

This invention is constructed as described above, in which a cylindrical support means is installed so as to be rotatable about its axis, and a locking protrusion is provided on the support means eccentrically from the axis at the support end surface thereof. Since the supporting means does not have corners, it does not become an obstacle, and the locking protrusion can be moved in the horizontal direction simply by rotating the supporting means. Thus, it is no longer necessary to form a long hole in the workbench base for horizontally moving the support means, and the processing cost of the workbench jig can be reduced accordingly.

[Brief explanation of the drawing]

Figure 1 shows a conventional example, in which a is a plan view, b is a front view,
C is a side view, d is an enlarged bottom view of the inside part of the circle line in b, FIG. 2 shows an embodiment of this invention, of which a is a plan view, b is a front view, C is a side view, and d is a It is an enlarged plan view of the inside part of the circle line in b. End: Supporting means, 10: Locking protrusion.
