Grinding device for burrs of aluminum end ring of cast-aluminum rotor

Abstract

The invention discloses a grinding device for burrs of an aluminum end ring of a cast-aluminum rotor. The grinding device comprises an L-shaped machine base, the machine base comprises a bottom plate and a vertical supporting plate at the rear end of the bottom plate, a rectangular grinding seat is formed at the upper end of the supporting plate, and an open groove penetrating through the front end face of the grinding seat is formed in the lower end face of the grinding seat. Two transverse friction wheels are inserted into the open groove of the grinding seat, and the lower ends of the friction wheels are exposed out of the lower end face of the grinding seat. A transmission gear is inserted between the friction wheels, the transmission gear and the friction wheels are fixed to a connecting shaft in an inserted and sleeved mode, and the two ends of the connecting shaft are hinged to the grinding seat through bearings. An inserting groove communicating with the open groove is formed in the upper end face of the portion, over the transmission gear, of the grinding seat, a driving gear is inserted into the inserting groove, and the driving gear is meshed with the transmission gear.

Description

technical field [0001] The invention relates to the technical field of motor rotors, in particular to a device for grinding burrs on aluminum end rings of cast aluminum rotors. Background technique [0002] The stator and rotor are important components of the motor. Some current rotors include an iron core composed of silicon steel sheet laminations. The iron core is formed into a rough blank of the rotor after casting aluminum, and then the rough blank is subjected to rough turning, shelling and finishing. Car and other processes, it is necessary to grind the aluminum end rings at both ends of the rotor to remove burrs. The existing deburring method is to use the hand-held rotor to rotate the burr roller for grinding, but the hand-held rotor grinding method has certain safety. Affected, a more secure grinding device is needed. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art and provide a grinding dev...
