[0002] As the foundation of the automotive industry, auto parts are essential factors to support the sustainable and healthy development of the automotive industry. In particular, the current vigorous and full-scale independent development and innovation in the automotive industry requires a strong parts system to support it. For automotive tubular parts, which are basically made of metal materials, their surfaces are rough with burrs and flash after initial forming, and need to be polished.

[0003] At present, when grinding tubular automobile parts, a clamp is used to clamp the automobile tubular parts and grind them with a handheld grinding wheel. The grinding speed is slow, the efficiency is low, and the labor intensity is high. Some parts are ground by a grinding motor to drive a grinding wheel to grind the automobile parts. In this process, the staff needs to fix the automobile parts in the clamp, and then start the grinding motor to grind them. After the grinding is completed, the grinding motor is stopped, the automobile parts in the clamp are taken out, and then new automobile parts are fixed. Continuous grinding cannot be performed. When the automobile parts are taken out and installed, the motor is in a standby state, and the grinding efficiency is low. Therefore, a grinder for automobile parts is proposed.
