Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts processing, in particular to a clamp for automobile parts processing. Background Art

[0002] Auto parts refer to various parts and devices used in automobile production, repair, maintenance and improvement. Their function is to ensure the normal operation of the automobile and to improve the performance and function of the automobile when necessary. Auto parts are the various units that constitute the entire automobile and a product that serves the automobile. All parts, assemblies, components (including their basic parts) and assemblies that are suitable for automobiles are collectively referred to as auto parts.

[0003] After searching, the patent (application number: 202222802190.1) discloses "a clamp for processing auto parts". When the movable plate moves, the second protrusion on the surface of the round rod moves in the movable groove opened on the surface of the movable plate. When the round rod moves, the round rod drives the clamp to move toward the surface of the auto part, so that the rubber pad on the surface of the clamp is clamped with the surface of the auto part. When the clamp clamps and fixes the auto part, the clamp can change different positions, and then can process auto parts of different sizes. When the size is too large or too small, the auto parts can be processed. However, the device has the following problems during use:

[0004] First, although the clamping plate in the fixture can be changed to different positions to process auto parts of different sizes, the movable clamping plate in the fixture is the most common function of the auto parts fixture. After the fixture clamps the parts, the processing angle of the parts cannot be automatically adjusted, which increases the difficulty of processing;

[0005] Secondly, the accessories can only be fixed by two opposite clamps, with fewer positioning points. However, during processing, the accessories usually need to be stressed in different directions, resulting in uneven stress on the accessories during processing, which can easily damage the accessories.

[0006] In addition, the accessories will be removed from the fixture after processing, but the dust generated during the processing will remain in the fixture. The long-term accumulation of dust in the fixture will contaminate the fixture and affect the sensitivity of the fixture. Utility Model Content
