End is connected with blanking cover.
The locating plate is in " V " type structure, and locating plate is made of antifriction alloy.
It is additionally provided in housing screw end for preventing the compression for weighing workpiece wounded head living, compresses head living by nylon material system
At.
Supporting block, locating piece and positioning body are connected by screw with L-type chuck body respectively.
Compared with prior art, the invention has the following beneficial technical effects:
Wire cutting positioning fixture disclosed by the invention, including the chuck body being of an L-shaped structure, chuck body is on one side
The fixed edge being connected with workbench forms the locating piece of the spherical anchor point of band first on the inside of fixed edge, and for installing
The supporting block of auxiliary jacking device and housing screw forms two locating plates of band and one the on the inside of the another side of chuck body
The positioning body of two spherical anchor points, positions for workpiece.When using this fixture clamping workpiece, workpiece is fixed with interfix benchmark
Position, makes the cantilevered out chuck body in linear cutter position；When clamping workpiece, the spring force generated by fixture auxiliary jacking device makes work
Part and locating plate and spherical anchor point are voluntarily bonded, and are then compressed with housing screw, can extremely convenient ground clamping workpiece, and surely
It is fixed reliable, it is suitble to similar structures workpiece linear cutter to use, the workpiece for being especially suitable for the wire cutting of shape entirety is used.Workpiece is straight simultaneously
Positioning, linear cutter in fixture are connect, the multiple tracks auxiliary processes such as casting positioning alloy, removal positioning alloy is eliminated, simplifies
Technique, improves part production efficiency.
Further, auxiliary jacking device is made of top-fastening rod, spring and blanking cover；Two locating plates on positioning body are V
Type antifriction alloy locating plate, when clamping workpiece, unclamping top-fastening rod makes it by spring force top tight workpiece, can fully ensure that workpiece
Two V-type antifriction alloy locating plates of section positioning datum and this fit closely, and by tightening housing screw, make its contact workpiece table
The clamping to workpiece is realized in face.
Further, workpiece damage in order to prevent is additionally provided with compression head living in housing screw end, and compression head living is by Buddhist nun
Imperial material is made.
