A rotating ring 12 is provided at the bottom of the movable sleeve 7, and the rotating ring 12 is threadedly connected to the threaded rod 6. Cylinders 2 17 are fixedly installed on the left and right sides of the top of the workbench 1. A track 14 is fixedly connected to the central axis of the top of the workbench 1. A moving block 19 is fixedly connected to the bottom of the L-shaped block 15. The moving block 19 is slidably connected to the inner wall of the track 14. Through the setting of the moving block 19, a guiding effect is played on the fixed bar 16 during the movement process, which improves the stability of the fixed bar 16 during use. An iron core placement plate 18 is provided on the top of the track 14, and the bottom of the iron core placement plate 18 is fixedly connected to the top of the workbench 1. The output ends of the cylinders 2 17 are fixedly connected with L-shaped blocks 15, and the tops of the L-shaped blocks 15 are fixedly connected with fixed bars 16. The inner cavity of the iron core placement plate 18 is filled with an iron core, and the surfaces of the two fixed bars 16 are in contact with the inner diameter of the iron core. Through the setting of the iron core placement plate 18, the iron core plays a supporting role during the grinding process, which mentions the stability of the iron core during the grinding process.

[0023] Working principle: When the utility model is used, the user first places the iron core in the inner cavity of the iron core placement plate 18, at which time the two fixing bars 16 are at the closest distance, and then the two cylinders 17 are simultaneously turned on, so that the output end of the cylinder 17 will drive the two L-shaped blocks 15 to move away from each other on the inner wall of the track 14, and then the fixing bar 16 will fix the inner diameter of the iron core to ensure the stability of the iron core during the grinding process, and then the user rotates the rotating ring 12, so that the sliding sleeve 7 will rise, and then the slider 10 will expand and slide outward in the inner cavity of the cross-shaped plate 11, so that the grinding plate 13 will expand to the surface of the iron core, and then the rotating ring 1 stops rotating. 2, then the output end of the cylinder 1 3 will drive the movable plate 4 to descend to the appropriate grinding position, and then the motor 5 will be started. The output shaft of the motor 5 will drive the threaded rod 6, the sliding sleeve 7 and the grinding plate 13 to rotate, and then the grinding plate 13 will rotate and grind the surface of the iron core. Since there is a dust cover around the iron core placement plate 18, the floating of grinding dust is avoided during the grinding process. After the grinding is completed, the motor 5 is turned off, and then the output end of the cylinder 1 3 will rise, and the grinding plate 13 will be out of contact with the iron core. The cylinder 2 17 is started, and the two fixing bars 16 move toward each other and are out of fixation with the iron core. Finally, the user takes the polished iron core out of the inner cavity of the iron core placement plate 18.

[0024] In summary: the three-phase motor core surface grinding device places the core in the inner cavity of the core placement plate 18, and uses the track 14, L-shaped block 15 and cylinder 2 17 in coordination, so that the fixing bar 16 can fix the core to avoid deviation during grinding, and then the fixing bar 16 will not accidentally damage the surface of the core, and the diameter of the grinding plate 13 during grinding is adjusted through the coordinated use of the sliding sleeve 7, the cross plate 11 and the rotating ring 12, and finally the motor 5 is started to grind the core.
