A linear drive mechanism 13 for driving the discharge plate 14 to move is installed on the polishing box 1; a chassis 3 is arranged at the bottom end of the polishing box 1; the bottom end inner cavity of the polishing box 1 is of a funnel-shaped structure. Such a setting enables the abrasive and the workpiece to slide downward along the inclined surface at the bottom end of the polishing box 1, making it convenient for the abrasive and the workpiece to be discharged; a vibration motor is installed at the bottom end of the polishing box 1. By installing the vibration motor, the discharge speed and the filtering speed of the device can be improved.

[0024] The stirring mechanism is installed on the polishing box 1. The stirring mechanism includes a power component, an inner cylinder 16, an outer cylinder 17, and multiple stirring rods 18. The inner cylinder 16 is rotatably installed inside the polishing box 1. The power component is installed on the polishing box 1 to drive the inner cylinder 16 to rotate. The outer cylinder 17 is vertically slidably installed on the inner cylinder 16. Multiple stirring rods 18 are all installed on the outer cylinder 17. The power component includes a servo motor 9 and a speed reducer 10. The output end of the servo motor 9 is connected to the input end of the speed reducer 10. The output end of the speed reducer 10 is connected to the inner cylinder 16. The cooperation of the servo motor 9 and the speed reducer 10 can increase the output torque of the power component.

[0025] The sliding rod 25 is connected to the outer cylinder 17. A circular chute 101 is formed on the inner wall of the polishing box 1. The top end of the chute 101 is located at the upper end of the inner wall of the polishing box 1, and the bottom end of the chute 101 is located in the middle of the inner wall of the polishing box 1. The end of the sliding rod 25 is movably arranged inside the chute 101.

[0026] The material turning assembly is installed on the outer cylinder 17 to turn the abrasive inside the polishing box 1. The material turning assembly includes a rotating shaft 19, a gear 21, a rack 22, and multiple turning rods 20. The rotating shaft 19 is rotatably installed on the outer cylinder 17. Multiple turning rods 20 are all installed on the rotating shaft 19. The end of the rotating shaft 19 extends to the inside of the inner cylinder 16. An activity hole 161 for the up and down movement of the rotating shaft 19 is vertically formed on the inner cylinder 16. The inner end of the rotating shaft 19 is connected to the gear 21. The rack 22 is vertically installed inside the inner cylinder 16, and the rack 22 meshes with the gear 21. During the up and down reciprocating movement of the outer cylinder 17, the rotating shaft 19 and the gear 21 are driven to move. Since the gear 21 meshes with the rack 22, the gear 21 can rotate during the up and down movement, thereby driving the rotating shaft 19 to rotate self - sufficiently. The rotating shaft 19 drives the turning rods 20 to rotate, thereby realizing the up and down turning of the material to improve the stirring effect.

[0027] The workpiece (gearbox plug) and the abrasive are both put into the inside of the polishing box 1 through the feed hopper 8. Subsequently, the power component is set to drive the inner cylinder 16 to rotate. The rotation of the inner cylinder 16 drives the outer cylinder 17 to rotate. The rotation of the outer cylinder 17 drives multiple stirring rods 18 to rotate, thereby realizing the stirring of the workpiece and the abrasive. During this process, the end of the sliding rod 25 slides inside the chute 101, thereby driving the outer cylinder 17 to reciprocate up and down. The outer cylinder 17 drives multiple stirring rods 18 to reciprocate, so as to improve the stirring range of the device. At the same time, through the setting of the material turning assembly, the outer cylinder 17 can drive the material turning assembly to turn the abrasive up and down during the up and down movement, so as to improve the polishing effect on the workpiece.
