The production efficiency of the magnetic bearing is improved under the premise of ensuring the safe assembly of the magnetic bearing. After completing the assembly of one permanent magnet, the permanent magnet assembly component 6 can be rotated under the guidance of the annular guide structure 7 to move the permanent magnet assembly component 6 to another permanent magnet fixing groove 5 for the next assembly, thereby realizing the assembly of the permanent magnets one by one.

[0023] Specifically, the permanent magnet assembly component 6 includes an assembly seat 8, in which a permanent magnet limiting chute 9 with an inverted T-shaped cross section is provided.

When assembling the permanent magnet, the permanent magnet is placed in the feeding trough, and then the permanent magnet is pushed into the permanent magnet fixing groove 5 by the pushing structure, which can avoid injuries to the assembly workers during assembly. Before the permanent magnet enters the permanent magnet fixing groove 5, the permanent magnet limiting chute 9 with an inverted T-shaped cross section can limit and guide the permanent magnet.

[0024] Specifically, the pusher structure includes a pusher plate 11 disposed on the side of the feed trough 10 away from the permanent magnet limiting slide groove 9, and a pusher rod 12 is connected to the pusher plate 11. The pusher rod 12 and the assembly seat 8 are slidably matched, and a reset spring is connected between the pusher rod 12 and the assembly seat 8. The permanent magnet can be pushed from the feed trough into the permanent magnet limiting slide groove 9 through the pusher rod 12 and the pusher plate 11, and then pushed into the permanent magnet fixing groove 5 through the permanent magnet limiting slide groove 9. After the assembly is completed, the reset spring can drive the pusher rod 12 and the pusher plate to move and reset.

The four fixed blocks 15 can be driven to move synchronously by the vertical guide drive assembly. The vertical guide drive assembly includes a driving slider 16 with a rectangular cross-section. The bottom of the base 1 is fixedly connected to a lifting driver 17 connected to the driving slider 16. The four side walls of the driving slider 16 correspond to the four fixed blocks 15 respectively, and a guide slider structure connected to the fixed block 15 is arranged on the side wall of the driving slider 16. The guide slider structure includes a guide seat 18. The guide seat 18 has a guide block 19 with a T-shaped cross-section and an inclined arrangement at one end away from the driving slider 16. The fixed block 15 is provided with a T-shaped guide groove 20 that slides with the guide block 19. The lifting driver 17 can drive the driving slider 16 to lift in the vertical direction. The lifting of the driving slider in the vertical direction can drive the guide seat 18 to lift. The lifting of the guide seat can drive the fixed block 15 to move horizontally toward or away from the magnetic bearing core 2 through the cooperation of the guide block 19 and the T-shaped guide groove 20 on the fixed block 15. When the four fixed blocks and the inner ring of the magnetic bearing core 2 are abutted, the magnetic bearing core 2 can be fixed and positioned.
