[0051] Working principle: First, turn on the two No. 1 electric cylinders 209 to respectively drive the two limit bars 208 to move, and the movement of the two limit bars 208 drives the two support plates 203 to move, and the movement of the two support plates 203 drives the polishing wheel 204 and the driving wheel 205 to move, so as to facilitate the processing of circular rings of different sizes, and turn on the No. 2 electric cylinder 311 to drive the moving plate 309 to move, and the movement of the moving plate 309 drives the polishing rod 310 to move, so as to adjust the height of the polishing rod 310, so as to facilitate the polishing of the inner and outer surfaces of circular rings of different sizes, and then turn on the No. 1 motor 109 to drive the rotating drum 412 to rotate, and the rotation of the rotating drum 412 drives the moving rod 413 to rotate, and the rotation of the moving rod 413 drives the first bevel gear 4 14 rotates, the second bevel gear 415 is driven to rotate by the rotation of the first bevel gear 414, the second screw 409 is driven to rotate by the rotation of the second bevel gear 415, the lifting plate 408 is driven to move by the rotation of the second screw 409, the mounting frame 404 is driven to move by the movement of the lifting plate 408, the rotating roller 406 is driven to move by the movement of the mounting frame 404, and the height of the rotating roller 406 is adjusted. At the same time, the first screw 407 is driven to rotate by the rotation of the rotating drum 412, the rectangular plate 402 is driven to move by the rotation of the first screw 407, the lifting plate 408 is driven to move by the movement of the rectangular plate 402, and the rotating rollers 406 are driven to move closer to each other by the movement of the lifting plate 408, so as to facilitate the support of circular rings of different sizes;

[0052] Secondly, place the ring on the two rotating rollers 406, turn on the third motor 307 to drive the rotating rod 305 to rotate half a circle, and drive the rotating disk 303 to rotate half a circle through the rotating rod 305, and drive the limiting rod 304 to make a semi-circular motion through the rotating disk 303. At this time, the semi-circular motion of the limiting rod 304 can be decomposed into lateral movement and longitudinal movement. When the limiting rod 304 moves horizontally, the limiting rod 304 slides inside the slide groove of the mounting seat 302. When the limiting rod 304 moves longitudinally, it drives the mounting seat 302 to move in the direction of the fixed plate 101, so that the polishing rod 310 is inserted into the inside of the ring and the outer surface of the inner ring of the ring. The rotating rod 305 rotates half a circle to drive the two vertical rods 102 to rotate half a circle, the two vertical rods 102 rotate half a circle to drive the two turntables 103 to rotate half a circle, and the turntable 103 rotates half a circle to drive the guide rod 104 to make a semi-circular motion. At this time, the semi-circular motion can be decomposed into lateral movement and longitudinal movement. When the guide rod 104 moves horizontally, the guide rod 104 is slidably set inside the slide grooves of the moving platform 201 and the mounting platform 202. When the guide rod 104 moves longitudinally, the guide rod 104 drives the moving platform 201 and the mounting platform 202 to approach each other, so that the outer surfaces of the polishing wheel 204 and the driving wheel 205 are in contact with the outer surface of the outer ring of the annulus.

[0053] Then, the two No. 2 motors 206, the No. 4 motor 312 and the vacuum cleaner 314 are turned on, and the two No. 2 motors 206 drive the polishing wheel 204 and the driving wheel 205 to rotate respectively, and the driving wheel 205 drives the ring to rotate, and the outer surface of the outer ring of the ring is polished by the polishing wheel 204, and at the same time, the No. 4 motor 312 drives the polishing rod 310 to rotate, and the inner outer surface of the ring is polished by the polishing rod 310, and then the dust collector 314 sucks the debris generated during polishing, so that the debris is stored in the collection box 502, which is convenient for cleaning;

[0054] Finally, when polishing is completed, turn on the third motor 307 to drive the rotating rod 305 to rotate half a circle, so that the polishing rod 310 returns to its original position, and the rotating rod 305 rotates half a circle to drive the two vertical rods 102 to rotate half a circle, so that the polishing wheel 204 and the driving wheel 205 return to their original positions. At this time, the movement of the moving platform 201 and the mounting platform 202 drives the slide bar 207 to move, and the movement of the slide bar 207 drives the tooth plate 211 to move. When the tooth plate 211 and the transmission gear 111 are meshed, the transmission gear 111 is driven to rotate, and the rotation of the transmission gear 111 drives the one-way bearing 110 to rotate. At this time, the inner and outer rings of the one-way bearing 110 rotate simultaneously to drive the rotating rod 105 to rotate. At this time, the spring 112 is driven by the external force By means of the lower deformation, the rotation of the rotating rod 105 drives the rotating bar 106 to rotate, the rotation of the rotating bar 106 drives the swinging bar 107 to swing, the swinging bar 107 pulls the moving bar 401 to move, so that the two moving bars 401 move away from each other, and the movement of the moving bar 401 drives the rotating roller 406 to move, so that the two rotating rollers 406 move away from each other. At this time, the polished ring falls downward through the gap between the rotating rollers 406 for unloading, and when the tooth plate 211 and the transmission gear 111 are disengaged, the spring 112 releases the force generated by the deformation and drives the rotation of the rotating rod 105 back to its original position, thereby driving the moving bar 401 and the rotating roller 406 back to their original positions, so as to facilitate the processing of the next ring.
