Automobile part clamping device

Abstract

The invention discloses an automobile part clamping device. The automobile part clamping device comprises a bottom plate, wherein a clamping mechanism is fixedly mounted on the bottom plate; the clamping mechanism comprises a clamping base; the clamping base is U-shaped; a pair of guide shafts is fixedly connected between the clamping base; a pair of limiting plates is arranged on the guide shafts in a sliding mode; one end of each limiting plate is rotatably equipped with a threaded rod; the threaded rods are in threaded insertion at the two ends of the clamping base; one end of each threaded rod is fixedly connected with a rotary block; mounting blocks are fixedly connected on the side walls at the two ends of the bottom plate; and mounting holes are formed in the mounting blocks. Compared with the prior art, the automobile part clamping device can extrude an arc-shaped plate through a shaft part, so that a friction plate on the surface of the arc-shaped plate fits to the surface of the shaft part, and therefore, a contact area between the shaft part and a clamping block can be increased; and in a long-time grinding process, an arc-shaped cavity can be heated to expand, so that interaction force between the arc-shaped cavity and the shaft part can be increased, friction force between the shaft part and the clamping block is increased, and therefore, part loosening caused by insufficient clamping force in the grinding process is avoided.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a clamping device for auto parts. Background technique [0002] Auto parts are the various units that make up the whole car and a product that serves the car. There are many kinds of auto parts. With the improvement of people's living standards, people consume more and more cars, and the market for auto parts is getting bigger and bigger. In recent years, auto parts manufacturers are also developing rapidly. [0003] For the deburring and grinding of shaft auto parts, fixtures are usually used, but most of the existing fixtures have excessive clamping force, which will leave indentations on the surface of shaft parts, resulting in the need for reprocessing or scrapping the parts. Or, due to insufficient clamping force, the shaft accessories will appear in the process of deburring and grinding, and there will be problems with the flatness of the grinding. Especiall...

Problems solved by technology

[0003] For the deburring and grinding of shaft auto parts, fixtures are usually used, but most of the existing fixtures have excessive clamping force, which will leave indentations on the surface of shaft parts, resulting in the need for reprocessing or scrapping the parts. Or, due to insufficient clamping force, the shaft accessories will appear in the process of deburring and grinding, and there will be problems with the flatness of the grinding. Especially in the long-term grinding process, the clamping force is more likely to be insufficient. Therefore, We propose a clamping device for auto parts to solve the above problems
