The power body 136 is fixed to the drive holder 13 with its power end extending into the drum 131, the power body 136 being coaxial with the drum 131. The arc-shaped bodies 137 are evenly distributed on the power body 136, and a gap is arranged between the arc-shaped bodies 137, and the driving block 134 is positioned in the gap.

The drive clamp 13 also includes a lug 138 and a second spring 139. The lifting lug 138 is mounted on the drive clamp 13. The second spring 139 is connected to the fixed table 12, the second spring 139 has a hook 1391, and the hook 1391 is connected to the lifting lug 138.

The process of driving the clamper 13 to support the inner wall of the bearing outer ring is as follows: the arc-shaped body 137 is driven to rotate through the power body 136, so that the arc surface of the arc-shaped body 137 props against the driving block 134 to move outwards, the ejecting part 132 on the driving connecting rod 133 extends out of the inner wall of the bearing outer ring, at the moment, the arc-shaped body 137 continues to push the driving block 134 to move, the driving block 134 further extends into the connecting rod 133 to compress the first spring 135, and the bearing outer ring is fixedly clamped by the ejecting part 132.

When polishing, the power body 136 drives the bearing outer ring to rotate, and then the outer surface of the bearing outer ring is polished comprehensively.

After finishing polishing, starting the bidirectional telescopic structure 107 to pull the sliding block 106 to move relatively, so that the supporting rod 11 deflects towards the middle of the supporting assistor 10, so that the supporting assistor 10 is highly lowered, at this time, the second spring 139 on the driving holder 13 cannot bear the driving holder 13 holding the outer ring of the bearing, so that the driving holder 13 rotates downwards, so that the outer ring of the bearing faces the conveying belt 16, then the arc-shaped body 137 is driven to rotate reversely by the power body 136, so that the driving block 134 resets, at this time, the compressed first spring 135 resets when keeping the supporting connecting rod 133 and the ejector 132, the clamping force of the ejector 132 on the outer ring of the bearing is gradually reduced, until the first spring 135 does not push the connecting rod 133 and the ejector 132 to abut against the inner wall of the outer ring of the bearing any more, so that the outer ring of the bearing can slowly fall.

A method of sanding comprising the steps of:

feeding, starting the first telescopic structure 1 to drive the material pushing plate 2 to move forwards, enabling the transmission rod 21 to extrude the rotating arm 5 on the synchronous clamp holder 4, enabling the transmission rod 21 to extrude the rotating arm 5 under the blocking of the front end wall surface of the first sliding groove 91 of the positioning table 9, enabling the rotating arm 5 to rotate, enabling the transmission rod 21 and the material pushing plate 2 to move to the front end position, and enabling the outer ring of the bearing to fall into the position of the conveying table 3 before the material pushing plate 2 moves.

During clamping, the rotating arm 5 rotates, the driven rod 6 is driven by the driving gear 52 to move, so that the movable rod 7 pushes the clamping piece 8 to extend to contact and clamp the bearing.

Pushing and butting materials, starting the first telescopic structure 1 to drive the material pushing plate 2 to move backwards and push the material pushing plate to fall into a bearing on the material pushing plate 2, so that the transmission rod 21 pushes the rotating arm 5 to drive the synchronous clamp holder 4 to slide backwards in the first sliding groove 91 of the positioning table 9, and the clamped bearing outer ring is sleeved into the driving clamp holder 13 and the periphery of the bearing outer ring is attached to the supporting auxiliary device 10.

Fixing and resetting, supporting the inner wall of the clamped bearing outer ring through the driving clamp holder 13, then continuously pushing the synchronous clamp holder 4 to move backwards through the first telescopic structure 1, at the moment, the synchronous clamp holder 4 is blocked by the rear end wall surface of the first chute 91 of the positioning table 9, the rotating arm 5 rotates reversely under the extrusion of the transmission rod 21, and then the gear 52 is driven to drive the driven rod 6, the movable rod 7 and the clamping piece 8 to reset, so that the clamping piece 8 loosens the clamping of the bearing outer ring, and meanwhile, the bearing outer ring on the conveying table 3 is pushed to a specified position at the material pushing plate 2.

And returning to the original position by pushing the synchronous gripper 4 to move forwards through the first telescopic structure 1.

And (4) polishing, namely polishing the bearing outer ring fixed by the driving clamp 13 and supported by the supporting assistor 10 by an external polishing device.

Preferably, when the clamping piece 8 releases the clamping of the bearing outer ring and the bearing outer ring on the conveying table 3 is not pushed to the designated position by the material pushing plate 2, the material pushing plate 2 is continuously driven by the first telescopic structure 1 to push the bearing outer ring to move to the designated position, and at the moment, the transmission rod 21 on the material pushing plate 2 moves along the linear sliding groove 42.

Preferably, the process of driving the clamper 13 to support the inner wall of the bearing outer ring is as follows: the arc-shaped body 137 is driven to rotate through the power body 136, so that the arc surface of the arc-shaped body 137 props against the driving block 134 to move outwards, the ejecting part 132 on the driving connecting rod 133 extends out of the inner wall of the bearing outer ring, at the moment, the arc-shaped body 137 continues to push the driving block 134 to move, the driving block 134 further extends into the connecting rod 133 to compress the first spring 135, and the bearing outer ring is fixedly clamped by the ejecting part 132.

More preferably, during polishing, the power body 136 drives the bearing outer ring to rotate, so as to perform overall polishing on the outer surface of the bearing outer ring.

More preferably, when the bearing outer ring is ground, the ball 101 on the support aid 10 moves along the rotation direction of the bearing outer ring, and part of chips generated by grinding are concentrated in the chip removal port 104 along the rotation of the ball 101, so that the support aid 10 can discharge the chips from the chip removal port 105.

More preferably, after finishing the grinding, the bi-directional telescopic mechanism 107 is actuated to pull the sliding block 106 to move relatively, so that the supporting rod 11 is shifted toward the middle of the supporting auxiliary 10, so that the support aid 10 is lowered in height, at which time the second spring 139 on the drive holder 13 does not receive the drive holder 13 holding the outer race of the bearing, thereby causing the drive gripper 13 to rotate downwardly with the outer race of the bearing against the conveyor 16, after which the arcuate bodies 137 are driven by the power bodies 136 to rotate in opposite directions, make the drive block 134 reset, at this moment, the first spring 135 of compressed restores to the throne when keeping supporting connecting rod 133 and kicking piece 132, reduces the clamping-force of kicking piece 132 to the bearing inner race gradually, and until first spring 135 no longer promote connecting rod 133 and kicking piece 132 and withstand the bearing inner race inner wall to can make the bearing inner race slowly fall into to conveyer belt 16 through gravity on.
