Grinding device for inner surface and outer surface of flange coupling

The invention relates to the technical field of coupling grinding equipment, in particular to a flange coupling inner and outer surface grinding device which comprises a base, a rotating ring is rotatably connected to the circumferential surface of the base, an electromagnet base is fixedly connected to the upper surface of the base, and an adjusting assembly is arranged on the upper surface of the rotating ring. An adjusting assembly is arranged at the bottom end of the base, a recycling assembly is arranged at the bottom end of the adjusting assembly, a grinding assembly is arranged on the side, close to the center of the base, of the adjusting assembly, and a processing assembly is arranged on the upper surface of the adjusting assembly. And meanwhile, the joint between the column body and the disc body of the flange coupling is polished, the angle of polishing equipment does not need to be adjusted, and polishing of the outer surface of the flange coupling is not affected. 本发明涉及联轴器打磨设备技术领域，具体为一种凸缘联轴器的内外表面
