Four-force intersected single-workpiece linked clamping device

Abstract

The invention discloses a four-force intersected single-workpiece linked clamping device. The four-force intersected single-workpiece linked clamping device comprises a fixture body, a plurality of pressing plates, a plurality of V-shaped blocks, a circular cavity, a plunger, a screw plug, sliding columns and liquid plastic, wherein a plurality of open grooves are perpendicularly arranged on the fixture body and the internal part of each groove is rotatably connected with the pressing plate through rivets; two pressing plates are oppositely arranged and the V-shaped blocks are arranged below the two pressing plates; the circular cavity is horizontally arranged in the lower part of the fixture body, one end of the circular cavity is connected with the plunger, the other end of the circular cavity is connected with the screw plug and the sliding columns are respectively arranged at the tail ends of the circular cavity; one ends of the sliding columns are fixed with the lower parts of the pressing plates through screws; the circular cavity is filled with the liquid plastic. The our-force intersected single-workpiece linked clamping device provided by the invention has the advantages that one workpiece can be evenly clamped from all directions by operating one handle, multi-point clamping of the workpiece can be realized, the precision can be effectively improved and the device is applicable to the precision machining process.

Description
