[0025] The trimming mechanism 4 includes a telescopic rod 3 401, a connecting frame 402 and a trimming knife 403. The telescopic rod 3 401 is installed on the side of the grinding mechanism 6, the connecting frame 402 is installed on the telescopic end of the telescopic rod 3 401, and the trimming knife 403 is installed on the side of the connecting frame 402 away from the grinding mechanism 6;

[0026] Specifically, Figure 1 and Figure 3As shown, by placing the micromotor stamping part on the top of the processing table 2, the corners can be polished by the grinding mechanism 6, and the trimming mechanism 4 can trim the corners of the micromotor stamping part. The trimming surface of the trimming knife 403 fits the outer surface of the micromotor stamping part. The telescopic rod three 401 is connected to the trimming knife 403 through the connecting frame 402. By retracting the telescopic end of the telescopic rod three 401, the connecting frame 402 can drive the trimming knife 403 to approach the micromotor stamping part on the processing table 2. As the processing table 2 drives the micromotor stamping part to rotate, the trimming knife 403 can directly trim the corners of the micromotor stamping part.

[0027] Furthermore, a positioning groove 5 is provided on the top of the trimming knife 403, and a trimming knife 501 is installed inside the positioning groove 5;

[0028] Specifically, Figure 4 As shown, in order to achieve trimming and chamfering of the trimmed position of the trimmed micromotor stamping part, the trimming knife 501 is set inside the positioning groove 5.

[0035] Further, an air pump 7 is installed on the top of the processing box 1;

[0036] Specifically, Figure 1 As shown, in order to reduce the dust generated during the grinding process of the micromotor stamping parts, the debris generated by the grinding inside the processing box 1 can be discharged through the vacuum pump 7 by operating the vacuum pump 7.

[0037] Working principle: by putting the center hole of the micromotor stamping part on the outside of the fixed column 201, and then driving the arc plate 203 to move through the telescopic rod 1 202, so that the arc plate 203 fits with the inner wall of the fixed column 201, and then the micromotor stamping part can be fixed on the top of the processing table 2, at this time, the fixed frame 601 is driven to move through the telescopic rod 2 3, so that the polishing surface of the polishing roller 602 fits with the outer surface of the micromotor stamping part, and then the micromotor stamping part is driven to rotate through the processing table 2, and at the same time, the polishing roller 602 is rotated, so that the polishing roller 602 can be rotated to polish the corners of the micromotor stamping part.

[0038] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it.
