This fixing method is not stable enough, especially during processing, and the metal ring cannot maintain good stability. At the same time, when the metal ring is flipped, it is impossible to ensure that it is flipped a full 180 degrees and maintained in this state only by the motor, and subsequent stable grinding cannot be achieved.

By setting the guide rod 12 and the slider 13, the two nuts 11 will not rotate with the two-way threaded rod 10, thereby ensuring the normal operation of the clamping and fixing assembly, the inner wall of the connecting plate 9 is fixedly connected with a bearing plate, and the two-way threaded rod 10 is rotatably connected to the side wall of the bearing plate through the bearing, so as to ensure the stability of the two-way threaded rod 10, and the two-way threaded rod 10 is fixedly connected with a knob at one end close to the first rotating shaft 7 for easy operation;

[0027] The flip cleaning assembly includes a flip assembly and a cleaning assembly. The flip assembly includes a No. 3 rotating shaft 16 arranged on the side of the workbench 1. The No. 3 rotating shaft 16 is rotatably connected to the bottom surface of the workbench 1 through a bearing. The No. 3 rotating shaft 16 is circumferentially fixedly connected with a flip disc 17. The side end of the No. 2 rotating shaft 8 is fixedly connected with a flip gear 18. The circumferential side wall of the flip disc 17 is provided with a tooth groove 19. The side wall of the flip gear 18 is fixedly connected with two toggle rods 20. The inner bottom surface of the flip disc 17 is fixedly connected with an elastic paddle 21. The cleaning assembly includes a No. 3 rotating shaft 16 arranged on the side of the workbench 1. The two No. 4 rotating shafts 22 above the table 1 and the No. 3 rotating shaft 16 are fixedly connected with a driving wheel 23 in the circumference, and the two No. 4 rotating shafts 22 are fixedly connected with a driven wheel 24 in the circumference.

[0028] The detailed working process of the utility model is as follows:

[0029] During use, when the metal ring to be processed needs to be fixed, the metal ring is held and placed between the two arc-shaped clamping plates 15, and then the bidirectional threaded rod 10 is rotated. Under the limit of the guide rod 12 and the slider 13, the two nuts 11 are threadedly engaged with the bidirectional threaded rod 10, and move toward each other along the bidirectional threaded rod 10, thereby driving the two arc-shaped clamping plates 15 to move toward each other. The metal ring is clamped and fixed by the two gradually approaching arc-shaped clamping plates 15, and then the electric push rod 4 is started to make the surface of the grinding block 6 contact with the surface of the metal ring, and the electric motor 5 is turned on to perform the grinding operation;

[0030] When it is necessary to flip, the handle is turned to rotate the third rotating shaft 16. The third rotating shaft 16 rotates, drives the flip disc 17 to rotate, and drives the elastic paddle 21 to revolve. When the elastic paddle 21 contacts the toggle rod 20, the toggle rod 20 will give the flip gear 18 a movement trend. At this time, the flip gear 18 is meshed with the tooth groove 19 of the flip disc 17, so that the flip gear 18 rotates 180 degrees, and then drives the entire clamping and fixing assembly to flip through the second rotating shaft 8. After the flip is completed, the pitch of the flip gear 18 will be against the surface of the flip disc 17, so that the flip gear 18 is maintained in a very stable state to complete the flip. During the flip, the third rotating shaft 16 rotates, which in turn drives the driving wheel 23 to rotate. The driving wheel 23 rotates, and the two driven wheels 24 and the fourth rotating shaft 22 are driven to rotate through the belt transmission, and then the fan blades 25 are driven to rotate, generating airflow, which can clean the surface of the polished metal ring and reduce the subsequent workload.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
