Cover plate type clamping device

Abstract

The invention relates to a clamping device, in particular to a cover plate type clamping device. The cover plate type clamping device comprises a base, a supporting frame, a cover plate, a buckle plate, a guiding rod, a cam and a floating compression plate. The buckle plate and the base are arranged on the two sides of the supporting frame correspondingly, and the supporting frame is of a U-shapedstructure. The lower end of the buckle plate is hinged to a mounting table arranged on the outer side of the supporting frame, and the base is fixedly connected with the supporting frame. A guiding hole is formed in the base in the axial direction, the guiding rod is perpendicularly arranged in the guiding hole and slidably matched with the guiding hole. A guiding groove is formed in the middle of the guiding rod, an abutting pin is horizontally arranged at the lower end of the guiding groove, and the cam rotates in the guiding groove and abuts against the abutting pin. An activity space allowing the cam to rotate is formed in the guiding hole, a driving rod is arranged on the cam, the driving rod is horizontally arranged in the base and rotatably connected with the base, and a rotatablehandle is arranged at the outer end, extending out of the base, of the driving rod. By adopting the technical scheme, the cover plate type clamping device has the characteristics of being good in clamping effect and high in adaptability.

Description

Technical field [0001] The invention relates to a clamping device, in particular to a cover plate clamping device. Background technique [0002] The fixture is a device used to fix the processing object during the mechanical manufacturing process so that it occupies the correct position to accept construction or inspection; the existing fixtures are mainly divided into general fixtures and special fixtures; three-jaw chucks are typical general fixtures. It has a wide range of applications; the special fixture is a fixture designed for the processing of a certain part; however, whether it is a general fixture or a special fixture, it is usually clamped from a certain side of the workpiece at the same time, so that The clamping effect is not good, especially in the case of large vibration, it is easy to loosen; and for some irregular workpieces, especially for some cover plates, the shapes are different, but they are all flat, so the design is designed for such workpieces Special ...

[0002] The fixture is a device used to fix the processing object in the process of mechanical manufacturing so that it can occupy the correct position for construction or testing; the existing fixtures are mainly divided into general fixtures and special fixtures; the three-jaw chuck is a typical general fixture. Its application range is wide; and the special fixture is a fixture specially designed for the processing of a certain part; but whether it is a general fixture or a special fixture, it is usually clamped from one side of the workpiece at the same time, so that The clamping effect is not good, especially in the case of large vibration, it is easy to loosen; and for some irregular workpieces, especially for some cover plates, the shapes are different, but they are all flat, so the design for such workpieces Special fixtures need to invest in a large cost
