[0002] As the name implies, a fixture is a device used to clamp workpieces. It is a process device used to quickly tighten the workpiece during processing so that the machine tool, tool, and workpiece maintain the correct relative position. Fixtures are used in production to improve production efficiency and product quality. Some automotive parts require the use of fixtures during the production and processing process to improve the production efficiency and quality of automotive parts.

[0003] The existing clamping tooling for automobile parts production and processing, as described in the patent with announcement number CN215747964U, includes a base, and a connecting groove is arranged at the top of the base. The clamping tooling for automobile parts production is movably connected with a connecting column at the middle position of the top of the base. When in use, the connecting column is movably connected to the top of the base, and the connecting column and the connecting groove are connected and fixed by a fixing seat. When in use, the driving motor fixedly connected to one side of the top of the base is started to drive the linkage gear through the driving shaft to drive the adjusting gear plate and the connecting column to rotate, thereby achieving the purpose of driving the connecting groove to rotate. However, although this method solves the problem of adjusting the angle of the parts, as the motor stops running, the parts will automatically rotate when the machine tool cuts, causing the parts to deviate and damage the parts.
