In the above steps, when the first grinding assembly and the second grinding assembly work, the first electric push rod 22 is controlled to shrink to drive the moving plate 23 to move downwards, the moving plate 23 drives the pressing ring 24 to move downwards through the second slide rod 25, when the pressing ring 24 moves downwards, on the one hand, the grinding rod 12 is pushed to move downwards to compress the second spring 16, and on the other hand, the power screw 26 is pushed to rotate, when the power screw 26 rotates, the gear ring 14 is driven to rotate through the third gear 27, the gear ring 14 drives the first gear 11 to rotate, the first gear 11 drives the grinding rod 12 to rotate through the rotating rod 10, and when the first gear 11 rotates, under the action of the second gear 13 and the rotating plate 15, the rotating rod 10 rotates around the circumference direction of the protruding block 2a, so that the grinding rod 12 rotates around the circumference direction of the protruding block 2 a. When the polishing rod 12 rotates, the pressing ring 24 pushes the polishing rod 12 to move downwards, the circumferential outer side of the cover body 1a is contacted with the polishing rotator 12d through the transitional conical surface 12e, the polishing rotator 12d polishes the circumferential outer side of the cover body 1a, the cover body 1a is processed to be of a set size, and along with the continuous downward movement of the polishing rod 12, the second polishing conical surface 12g is contacted with the upper end of the circumferential side surface of the cover body 1a to realize upper chamfering of the circumferential side surface of the cover body 1 a.
Then, the first electric push rod 22 is controlled to extend to drive the movable plate 23 to move upwards, the movable plate 23 drives the pressing ring 24 to move upwards through the second sliding rod 25, the polishing rod 12 moves upwards under the action of the second spring 16 when the pressing ring 24 moves upwards, meanwhile, the pressing plate drives the power screw 26 to rotate reversely, the power screw 26 drives the gear ring 14 to rotate reversely through the third gear 27 when rotating reversely, the gear ring 14 drives the first gear 11 to rotate reversely, the first gear 11 drives the polishing rod 12 to rotate reversely through the rotating rod 10, and the rotating rod 10 rotates reversely around the circumference direction of the protruding block 2a under the action of the second gear 13 and the rotating plate 15 when the first gear 11 rotates, so that the polishing rod 12 rotates reversely and moves reversely around the circumference direction of the protruding block 2 a. The polishing rod 12 moves upward when rotating reversely, and because the polishing rotator 12d polishes the circumference outside of the cover body 1a, the circumference size of the cover body 1a is reduced compared with that before polishing, and therefore the second spring 16 pushes the polishing rod 12 upward so that the first polishing conical surface 12c contacts with the lower end of the circumference side surface of the cover body 1a to realize lower chamfering of the circumference side surface of the cover body 1 a.
In addition, when the rotating plate 15 rotates, the rotating plate 15 drives the rotating ring 17 to rotate through the first sliding rod 18, the rotating ring 17 drives the polishing ring 19 to polish the lower end of the annular convex edge 1b under the action of the third spring 21, and when the polishing is up to a set size, the rotating ring 17 is abutted against the lower end of the limiting ring 20. The first electric push rod 22 is controlled to repeatedly extend and retract for a plurality of times, so that polishing processing of the cover plate is realized.
In the above steps, after polishing, the first electric push rod 22 is in a fully extended state, the pressing ring 24 is located at the upper end of the arc-shaped side plate 3, the second electric push rod 28 is controlled to shrink to drive the pressing plate 29 to move upwards to leave the cover plate, at this time, the second spring 16 forces the polishing rod 12 to move upwards due to the cover plate abutting against the first polishing conical surface 12c, so that the polishing rod 12 pushes the cover plate to move upwards, and the annular convex edge 1b is separated from the positioning of the positioning assembly. And repeating the steps to realize polishing of the cover plate.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
