The invention belongs to special equipment for disassembling and maintaining
passenger train bearings in railway vehicle depots, and particularly relates to an internal-external full-automatic polisher for treating an inner ring and an outer ring of a
passenger train bearing. The internal-external full-automatic polisher comprises a body, an automatic feeding and discharging mechanism, an internal-external
polishing head and control mechanism, a
position sensor, an automatic identification mechanism, a touch screen and an electric appliance control box, a PLC (
programmable logic controller) electric appliance
control system is mounted in the electric appliance control box and electrically connected with the automatic feeding and discharging mechanism, the automatic workpiece identification mechanism and the internal-external
polishing head and control mechanism, a pneumatic control box is fixedly mounted on the lower portion of the side of the body, and a pneumatic
control system is mounted in the pneumatic control box and is connected with cylinders of the automatic feeding and discharging mechanism and the internal-external
polishing head and control mechanism through air pipes. Iron molds of the inner ring and the outer ring of the
passenger train bearing can be automatically grinded and polished, the internal-external full-automatic polisher is high in
automation degree, more environment-friendly, high in passenger
train bearing disassembling and maintaining efficiency, fine in quality and remarkable in economic benefit, and the labor intensity of workers is low.
