Motor rotor punching sheet stamping machining system

Abstract

The invention belongs to the technical field of motors, and particularly relates to a motor rotor punching sheet stamping machining system. The motor rotor punching sheet stamping machining system comprises a bottom plate, a mounting column and a disc are rotationally mounted on the bottom plate, an inner supporting mechanism and a guide rod are mounted on the disc, a plurality of positioning blocks are evenly and fixedly installed on the outer side wall of the installation column in the circumferential direction of the mounting column, positioning mechanisms matched with the positioning blocks are installed on the upper surface of the bottom plate, a sliding block is slidably installed on the upper surface of the bottom plate, a lead screw penetrating through the sliding block is rotatably installed on the bottom plate through a lead screw support, and a punching mechanism is installed on the sliding block. When annular silicon steel sheets are stamped, it is guaranteed that the rotating angles of the silicon steel sheets are consistent each time, the stamping forming quality of the motor rotor punching sheets is improved, abrasive dust of extension materials is prevented from being attached to grinding blocks and pressure bearing blocks, and the surface quality of the stamped silicon steel sheets is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a stamping and processing system for punching a motor rotor. Background technique [0002] The motor consists of two parts, the rotor and the stator. It is used to realize the conversion device of electrical energy and mechanical energy and mechanical energy and electrical energy. The motor rotor is the rotating part in the motor. The rotor includes the rotor core, the rotor winding and the rotating shaft. The rotor core is generally made of 0.5 mm thick silicon steel sheets punched and laminated. CN113078780A discloses a servo motor rotor stamping manufacturing process, using a servo motor rotor stamping manufacturing equipment, the servo motor rotor stamping manufacturing equipment includes a conveyor, a stamping device, a limit device, a collection device and Winder. When using the above-mentioned servo motor rotor punching manufacturing equipment to manufacture a...

AI Technical Summary

Problems solved by technology

[0003] The following problems still exist in the stamping process of the motor rotor sheet stamping process: after stamping the edge of the annular silicon steel sheet through the cutter head, a downward extension material will be formed at the bottom edge of the stamped part of the silicon steel sheet, and this part of the extension material is attached to the On the inner wall of the pressure table, when the silicon steel sheet is rotated for another stamping after stamping, there will be an interaction force between the extension material and the pressure table, which will cause the silicon steel sheet to rotate at different angles each time, resulting in The uneven distribution of stamping openings at the edge of the silicon steel sheet adversely affects the quality of stamping and forming of the motor rotor sheet
