Mechanical part polishing device

The mechanical part polishing device comprises a base, a polishing mechanism and a fixing mechanism are arranged at the top of the base, a protection mechanism is arranged between the polishing mechanism and the fixing mechanism, a cleaning mechanism is arranged on the back face of the fixing mechanism, and a blowing mechanism is arranged on the back face of the polishing mechanism; vertical plates are arranged on the two sides of the top of the base, a forward and reverse screw rod driven by a motor I is arranged between the two sets of vertical plates, and the forward and reverse screw rod drives the grinding mechanism and the fixing mechanism to move so as to change the distance between the grinding mechanism and the fixing mechanism. According to the device, multiple sets of products can be machined at the same time so as to improve the efficiency, machining chippings can be well protected and collected, and the problems that the environment is affected due to chipping sputtering, and the chippings are no
