[0002] The rotor sheet is an important component of the motor. The rotor sheet is usually made of laminated silicon steel sheets and then fixed on the stator and rotor brackets or the rotating shaft. During the production of the rotor sheet, it is necessary to punch holes in the middle of the rotor sheet. For example, patent application number CN202021489041.9 discloses a rotor sheet stamping device for motor rotor production, comprising a stamping operation table, a rotor sheet and a push rod. A fixed plate is fixedly connected to the middle of the top of the stamping operation table and close to the back in the vertical direction. The top of the front side of the fixed plate is fixedly connected to a top plate in the horizontal longitudinal direction. The bottom of the top plate is fixedly connected to a hydraulic cylinder. The output end of the hydraulic cylinder is fixedly connected to a stamping block. Through the structural design of the stamping operating table, buffer groove, push rod, connecting plate, return spring and pad, the rotor plate can be effectively conveniently removed after the stamping process is completed, avoiding the situation where the rotor plate is always completely located inside the buffer groove, making it inconvenient to remove. This solves the problem of affecting the stamping efficiency of the rotor plate by the staff due to the inconvenience in removing and removing the rotor plate. However, in the above technical solution, the position of the rotor plate may be offset when the rotor plate is stamped, which will affect the quality and efficiency of the stamping.
