Limiting structure of rotor grinding device

Abstract

The invention discloses a limiting structure of a rotor grinding device. The limiting structure comprises an L-shaped machine base, the machine base comprises a bottom plate and a vertical supporting plate at the back end of the bottom plate, a vertical lifting air cylinder is fixed to the upper end surface of the bottom plate, a bracket is fixed to a piston rod of the lifting air cylinder, a vertical guide rail is inserted into the back end of the bracket, and the guide rail is fixed to the front end surface of the supporting plate; the limiting structure is characterized in that a transverse V-shaped notch is formed in the upper end surface of the bracket, transverse arc-shaped clamping grooves are formed in the two side walls of the notch, cylindrical rollers are inserted into the clamping grooves, the two ends of each cylindrical roller extend out of the two side walls of the bracket, the outer walls of the lower sides of the two ends of each cylindrical roller abut against brake pads, the brake pads are fixed to horizontal limiting supporting plates, and the limiting supporting plates are fixed to the front end surfaces of the supporting plates on the two sides of the bracket.

Description

technical field [0001] The invention relates to the technical field of motor rotors, and more specifically relates to a position-limiting structure of a rotor grinding device. 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 required. Therefore, it is proposed to use a bracket with cylindrical rollers to support the rotor. The rotor is in contact with the friction wheel, and the ...
