With the continuous improvement of living standards, the use of automobiles is increasing, and the factories' manufacturing and processing capabilities of automobiles are becoming stronger and stronger. At present, many small parts are used in the automobile manufacturing process. These parts need to be placed on special tools during the processing and oiling process to prevent these parts from being damaged, while ensuring that the oiling process is smoother and the oiling effect is better.

In the utility model, the pressure cylinder is started by the clamping mechanism, so that the hydraulic rod drives the moving block to move, and then the two moving blocks drive the two clamping plates to move relative to each other, so as to quickly clamp and fix the automobile parts, and at the same time, it is convenient to adjust the clamping plate to move left and right to clamp and fix automobile parts of different sizes. When clamping and fixing the automobile parts, under the elastic force of the reset spring, it plays a buffering role to avoid damage to the automobile parts, thereby increasing practicality;

[0004] However, the above existing devices still have the following problems in actual use:

[0005] The above-mentioned existing device uses a spring to drive a clamp to clamp the parts. Since the spring has a certain elasticity, the clamping effect on the parts is poor, resulting in the parts moving during the clamping process, thereby reducing the clamping effect of the device on the parts. Therefore, a quick clamping device for automobile parts processing is needed. Utility Model Content
