The workpiece ejecting assembly 8 works once, and the motor rotor in the workpiece waiting groove 6 is ejected into the workpiece polishing groove 7. At the same time, the motor rotor in the workpiece polishing groove 7 is ejected into the discharging track 5.

[0030] A power frame 12 is arranged on the upper surface of the working base 1, and a pressing assembly 13 is arranged on the power frame 12. The pressing assembly 13 comprises a pressing pump 14, and a pressing head 15 is arranged below the pressing pump 14. Under the driving of the pressing pump 14, the pressing head 15 can move up and down. Track rods 16 are arranged on the two sides of the pressing head 15, and the track rods 16 penetrate through the power frame 12. Under the guidance of the track rods 16, the pressing head 15 can keep stable when moving up and down. A power wheel assembly 17 is arranged at the bottom of the pressing assembly 13, and the power wheel assembly 17 comprises a servo motor 18 and two power wheels 19. The servo motor 18 drives the power wheels 19 to rotate, and the power wheels 19 can drive the motor rotor to rotate when the motor rotor abuts against the power wheels 19.

[0031] The working base 1 is provided with a pressing platform assembly 20, which comprises a pressing platform 21, a fixed base 22 and eight supporting springs 23.
