[0002] The motor rotor is an important component of a motor. It usually refers to the rotating part inside the motor, which is responsible for converting electrical energy into mechanical energy. However, the motor rotor needs to be stamped after production, so stamping fixtures are used.

[0003] Chinese patent application number 202420652165.6 discloses a fixture for stamping motor rotor laminations, including a processing table. A support plate is fixedly connected to the upper surface of the processing table, and an electric push rod is fixedly connected to the lower surface of the support plate. A stamping head is fixedly connected to the lower end of the electric push rod. A stamping seat is fixedly connected to the upper surface of the processing table. A slot is provided on the front surface of the processing table, and a dust collection drawer is slidably connected to the inner surface of the slot. A first lead screw is rotatably connected to the inner surface of the processing table, and a first bevel gear is fixedly connected to the outer surface of the first lead screw. A connecting shaft is rotatably connected to the inner surface of the processing table, and a second bevel gear is fixedly connected to the outer surface of the connecting shaft.

This fixture allows for clamping different positions of different motor rotors, improving stability.

[0004] The current motor rotor lamination stamping and fixing fixture uses rectangular clamps on both sides to hold and fix the rotor, but its stability is poor and it is not convenient to disassemble and replace the clamping plates, resulting in poor practicality. Therefore, we propose a motor rotor lamination stamping and fixing fixture. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fixture for stamping and fixing motor rotor laminations, which solves the problems mentioned in the background section.

A fourth bevel gear column is also rotatably connected inside the second transmission groove via bearings. The fourth bevel gear column meshes with the four third bevel gear columns. One end of the third bevel gear column is fixedly connected to the second bevel gear column. The rotation of the fourth bevel gear column by the servo motor drives the four third bevel gear columns to rotate accordingly, which in turn drives the four second bevel gear columns to rotate, and then drives the four first bevel gear columns to rotate, thereby driving the threaded rod to rotate. The position of the clamping plate is adjusted by raising and lowering the connecting seat through the adjustment groove, so that the rotor can be clamped and fixed at different positions as needed.

[0013] This utility model provides a fixture for stamping and fixing motor rotor laminations, which has the following advantages:

[0014] 1. This motor rotor lamination stamping and fixing fixture uses four clamping plates to clamp and fix the outer side of the rotor from four directions, thereby improving its stability during clamping. The rotation of the fourth bevel gear column of the servo motor drives the four third bevel gear columns to rotate accordingly, then drives the four second bevel gear columns to rotate, and then drives the four first bevel gear columns to rotate, thereby driving the four threaded rods to rotate. In turn, the positions of the four clamping plates are adjusted by raising and lowering the four connecting seats through four adjustment slots, which improves the practicality of the motor rotor lamination stamping and fixing fixture.

[0015] 2. The motor rotor lamination stamping and fixing fixture allows for easy disassembly and replacement of the clamping plate as needed.

The first transmission slot 14 is also rotatably connected to a second bevel gear column 16 through a bearing. The first bevel gear column 15 and the second bevel gear column 16 mesh with each other. One end of the first bevel gear column 15 is fixedly connected to the threaded rod 10. Through the mutual cooperation of the first bevel gear column 15 and the second bevel gear column 16, the threaded rod 10 can be driven to rotate.

[0025] The processing table 1 has a second transmission groove 17 inside. Four corresponding third bevel gear columns 18 are rotatably connected inside the second transmission groove 17 via bearings. A fourth bevel gear column 19 is rotatably connected inside the second transmission groove 17 via bearings. The fourth bevel gear column 19 meshes with the four third bevel gear columns 18. One end of the third bevel gear column 18 is fixedly connected to the second bevel gear column 16.

The material is then placed in the center of the processing table 1. The controller 2 then starts the fourth bevel gear column 19 of the servo motor 20 to rotate, which in turn drives the four third bevel gear columns 18 to rotate accordingly, then drives the four second bevel gear columns 16 to rotate, and then drives the four first bevel gear columns 15 to rotate, thereby driving the four threaded rods 1... The rotor rotates 0, and then adjusts the position of the four clamping plates 29 by raising and lowering the four connecting seats 12 through the four adjusting grooves 9. Then, the multiple fixing bolts are loosened to release the limit on the first slide rod 23, so that the multiple sets of compression springs 25 rebound and push the first slide rod 23 to move. Then, the clamping plate 29 is pushed to fit against the rotor surface through the connecting block 26, and then fixed by fixing bolts. Then, the hydraulic telescopic rod 4 is activated by the controller 2 to push the stamping head 5 to process the rotor, so that the waste material falls into the collection hopper 8 through the stamping groove 6 for easy processing.
