[0027] It should be noted that: when the plastic magnetic rotor is chamfered and polished, part of the generated debris falls on the top of the turntable 54. The first motor 6 is started. Under the action of the first motor 6, the turntable 54 can be driven to rotate, so that the debris is subjected to a certain centrifugal force, so that the debris on the top of the turntable 54 can enter the interior of the collection box 51 through the collecting groove 53. At the same time, part of the debris generated by the chamfering and polishing can fall into the interior of the collection box 51 through the collecting groove 53, so that the debris generated by the chamfering and polishing of the plastic magnetic rotor can be uniformly collected. After the chamfering and polishing of the plastic magnetic rotor is completed, the positioning bolt 8 is rotated to disengage the positioning bolt 8 from the positioning plate 9 and the interior of the polishing box 1, and then the collection box 51 can be disassembled and assembled, so that the debris collected in the collection box 51 can be uniformly processed.

[0028] refer to Figure 2 and Figure 2 As shown, a groove 10 is formed inside the rotating disk 54 , and a spring 11 is welded to one side of the inner wall of the groove 10 .

[0029] A moving plate 12 is welded to one end of the spring 11 , and an elastic pad 13 is arranged on one side of the moving plate 12 .

[0030] It should be noted that: when the plastic magnetic rotor is fixed, the movable plate 12 is pushed, and the spring 11 can be compressed when the movable plate 12 moves, and then the plastic magnetic rotor is placed on the outside of the fixed rod 7, and the movable plate 12 is released. Under the elastic force of the spring 11, the top of the elastic pad 13 can be tightly fitted with the outside of the plastic magnetic rotor, and the height of the movable plate 12 will not affect the chamfering and polishing operation of the plastic magnetic rotor.

[0035] It should be noted that: when performing chamfering and polishing operations, the second motor 14 is started, and under the action of the second motor 14, the first screw mechanism 15 can be driven to operate, and then under the action of the first screw mechanism 15, the movable bar 16 can be moved, and when the movable bar 16 moves, the grinding disc 20 can be driven to move by the cylinder 18, and then the lateral position of the grinding disc 20 can be adjusted, and then the second screw mechanism 17 starts to operate. When the second screw mechanism 17 is operating, it can drive the cylinder 18 to move, and then the grinding disc 20 can be adjusted longitudinally. At the same time, under the action of the cylinder 18, the height of the grinding disc 20 can be adjusted, and then the plastic magnetic rotor can be chamfered and polished.

[0036] The working principle of a chamfering and polishing device provided by the utility model is as follows:

[0037] When the staff needs to chamfer and polish the plastic magnetic rotor, they first open the sealing door 3 and then push the movable plate 12. When the movable plate 12 moves, the spring 11 can be compressed, so that the spring 11 moves to the specified position. Then the staff places the plastic magnetic rotor on the outside of the fixed rod 7 and releases the movable plate 12. Under the elastic force of the spring 11, the movable plate 12 can position the plastic magnetic rotor. Then, according to starting the second motor 14, under the action of the second motor 14, the first screw mechanism 15 can drive the grinding disc 20 to move horizontally. At the same time, under the action of the second screw mechanism 17, the longitudinal position of the grinding disc 20 can be adjusted. Under the action of the cylinder 18, the grinding disc 20 can be moved horizontally. The height of the grinding disc 20 is adjusted so that the plastic magnetic rotor can be chamfered and polished. When the plastic magnetic rotor is chamfered and polished, some debris falls on the top of the turntable 54. The first motor 6 is started. Under the action of the first motor 6, the debris on the top of the turntable 54 can be subjected to a certain centrifugal force, so that the debris on the top of the turntable 54 can enter the interior of the collection box 51 through the collection groove 53. At the same time, some debris can directly enter the interior of the collection box 51 through the collection groove 53. At the same time, the fan 2 is started. Under the action of the fan 2, the dust inside the polishing box 1 can be extracted, and then uniformly collected and processed through the dust collecting box 21, so that the dust will not be emitted into the surrounding air.
