In the above steps, when the first polishing assembly and the second polishing assembly work, the first electric push rod 22 is controlled to contract to drive the moving plate 23 to move downwards, the moving plate 23 drives the press ring 24 to move downwards through the second slide rod 25, the press ring 24 pushes the polishing rod 12 to move downwards to compress the second spring 16 when moving downwards, on the other hand, the power screw 26 is pushed to rotate, the power screw 26 drives the gear ring 14 to rotate through the third gear 27 when rotating, the gear ring 14 drives the first gear 11 to rotate, the first gear 11 drives the polishing rod 12 to rotate through the rotating rod 10, and under the action of the second gear 13 and the rotating plate 15 when the first gear 11 rotates, the rotating rod 10 rotates around the circumferential direction of the bump 2a, so that the polishing rod 12 rotates around the circumferential direction of the bump 2a while rotating. When the grinding rod 12 rotates, the pressing ring 24 pushes the grinding rod 12 to move downwards, the outer side of the circumference of the cover body 1a is in contact with a grinding rotating body 12d through a transition conical surface 12e, the grinding rotating body 12d carries out grinding processing on the outer side of the circumference of the cover body 1a, the cover body 1a is processed to a set size, and along with the fact that the grinding rod 12 continues to move downwards, the second grinding conical surface 12g is in contact with the upper end of the circumference side face of the cover body 1a to achieve upper chamfering of the circumference side face of the cover body 1 a.
And then the first electric push rod 22 is controlled to extend out to drive the moving plate 23 to move upwards, the moving plate 23 drives the press ring 24 to move upwards through the second slide bar 25, the grinding rod 12 moves upwards under the action of the second spring 16 when the press ring 24 moves upwards, meanwhile, the press plate drives the power screw rod 26 to rotate reversely, the power screw rod 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 grinding rod 12 to rotate reversely through the rotating rod 10, the rotating rod 10 rotates reversely around the circumferential direction of the convex block 2a under the action of the second gear 13 and the rotating plate 15 when the first gear 11 rotates, and therefore the grinding rod 12 rotates reversely and moves reversely around the circumferential direction of the convex block 2a at the same time of reverse rotation. The polishing rod 12 moves upward when rotating in the reverse direction, and since the polishing rotating body 12d has polished the circumferential outer side of the cover body 1a, the circumferential dimension of the cover body 1a is reduced compared with that before polishing, and therefore the second spring 16 pushes the polishing rod 12 upward to make the first polishing conical surface 12c contact with the lower end of the circumferential side surface of the cover body 1a, so as to realize lower chamfering of the circumferential 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 grinding ring 19 to grind the lower end of the annular flange 1b under the action of the third spring 21, and when the annular flange is ground to a set size, the rotating ring 17 abuts 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 the grinding processing of the cover plate is realized.
In the above steps, after polishing, the first electric push rod 22 is in a completely extended state, the press ring 24 is located at the upper end of the arc-shaped side plate 3, the second electric push rod 28 is controlled to contract to drive the press plate 29 to move upward to leave the cover plate, at this time, the cover plate abuts against the first polishing conical surface 12c, the second spring 16 forces the polishing rod 12 to move upward, so that the polishing rod 12 pushes the cover plate to move upward, and the annular convex edge 1b is separated from the positioning of the positioning assembly. The polishing processing of the cover plate can be realized by repeating the steps.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
