[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work fixing device for a parallel type machine vise.

[0002]

2. Description of the Related Art With the spread of machining centers, it is possible to improve productivity by installing a plurality of machine vices in parallel on a machining table as a multi-row system and automatically operating continuously for as long as possible. However, it is necessary to position and fix a plurality of works under the same conditions.

In this respect, the conventional work fixing device is shown in FIG.
As shown in FIGS. 6 and 17, the set bolt (2) and the round bar (3) for the machine vise (1) are assembled in an orthogonal state via a fulcrum piece (4). A workpiece positioning bolt (5) parallel to the set bolt (2) is threadedly fastened at its tip end so as to move forward and backward, thus forming an overall jig form. (6) is a fixing nut for the positioning bolt (5).

Then, the set bolt (2) is replaced with the one shown in FIG.
As is clear from the above, the workpiece (W) is positioned and fixed by moving the positioning bolts (5) forward and backward after individually implanting and fixing them in the fixing blocks (7) of the parallel machine vise (1). There is.

[0005]

However, according to the above-mentioned structure, the positioning operation of the work (W) must be performed for each of the parallel type machine vise (1) one by one, which is very complicated and the work is difficult. Not only is it inefficient, but it is also difficult to adjust the positioning accuracy of multiple workpieces (W) in a uniform manner. This increases as the number of machine vise (1) arranged in parallel increases. It will occur remarkably.

[0006]

SUMMARY OF THE INVENTION The present invention is intended to solve such problems, a slide in which the configuration on a plurality of fixed block therefor, Ru is reciprocating work movement along the longitudinal direction of the each fixed block Multiple blocks are installed in parallel on a common vice body and fixed to the slide block.
