Polishing device for gear deburring

The invention relates to the technical field of gear machining, and particularly discloses a polishing device for gear deburring. The whole polishing device is composed of a supporting seat assembly, a rotating platform fixedly installed in the middle of the supporting seat assembly, a middle fixing assembly fixedly installed at the upper end of the rotating platform, a left polishing assembly arranged at the left end of the supporting seat assembly, a right polishing assembly arranged at the right end of the supporting seat assembly and a control assembly arranged on the side face of the right polishing assembly. In the working process, an end face grinding driving motor and a left sliding driving cylinder are started through a touch panel, the upper end and the lower end of a gear are ground and deburred through an end face grinding disc, and the grinding efficiency is improved; a gear tooth grinding driving motor, a right sliding driving cylinder and a right upper lifting driving cylinder are controlled th
