The first clamp 1 can rotate under the drive of the rotary drive mechanism 4, the roller 2 and the barrel sleeve 3 can change the positions under the action of the servo system 7, and the first clamp 1, the roller 2 and the barrel sleeve 3 can respectively clamp a fork head, a fork body and a fork opening of a target shifting fork to fix the shifting fork in a sectional mode. No matter whether the fork head axis of the target shifting fork is perpendicular to the fork opening or not, the fork head and the fork opening of the shifting fork can be respectively fixed, and therefore the shifting fork is integrally fixed. And the upper end face and the lower end face of the fork opening of the shifting fork can be turned over through the rotation of the first clamp 1, so that the purpose of milling the two end faces of the fork opening of the shifting fork can be achieved without changing the clamp and placing for the second time.

Polishing one end face of a fork opening of the target shifting fork:

step one, placing a shifting fork: a worker or other mechanical equipment sleeves the fork head of the target shifting fork on the first stop column 1a, and the fork opening of the shifting fork faces the outer side of the roller 2.

Step two, the first clamp 1 acts: the first rotary pressing cylinder 1b drives the first blocking piece 1c to abut against the upper surface of the target shifting fork head, the lower surface of the target shifting fork head is abutted by the platform 2a, and the upper surface and the lower surface of the target shifting fork head are fixed.

Step three, rotating the first clamp 1 to a specified position: the servo motor 4b drives the second gear 4c to rotate, the second gear 4c drives the first gear 4a to rotate, the first gear 4a is fixedly connected to the roller 2 to drive the roller 2 to rotate, and the first clamp 1 is fixedly arranged in the roller 2 to rotate along with the roller until the upper end face of the target shifting fork opening is positioned on the working face of the milling machine 8;

step four, the servo system 7 drives the support flat plate 7a to the designated position: the servo system 7 drives the support plate 7a to move, so that the cushion block 5c on the support plate 7a is just against the lower surface of the target shift fork body, the target shift fork is positioned at the middle of the two second shift posts 6a2 on the clamping plate 6a, and the support plate 7a stops moving and is fixed at the current position.

Step five, the third clamp 6 acts: the air cylinder 6b drives the clamping plate 6a to move towards the direction far away from the roller 2, and the clamping plate 6a can stably move under the action of the sliding groove 6a1 and the sliding rail 7a 1; the two second shift posts 6a2 sandwich the two outer sides of the target fork until the second shift post 6a2 abuts completely against the two outer sides of the target fork and cannot move. Two second gear posts 6a2 constitute firm triangle-shaped structure with a first gear post 1a, have not only fixed the fork mouth, are fixed the shift fork whole on the plane moreover, can not rock all around.

Step six, the second clamp 5 acts: the second rotary pressing cylinder 5a drives the second blocking piece 5b to abut against the upper surface of the target shifting fork body, the lower surface of the target shifting fork body is abutted by the cushion block 5c, and the upper surface and the lower surface of the target shifting fork body are fixed.

Step seven, the milling machine 8 acts as: and the milling machine 8 controls the milling cutter to mill the upper side end face of the target shifting fork opening.

In the above steps, the reason why the third clamp 6 acts first and then the second clamp 5 acts is that: if second anchor clamps 5 first act on, because the effect of second anchor clamps 5 pressure, third anchor clamps 6 can't effectual both sides face of propping the shift fork mouth when the effect, perhaps when third anchor clamps 6 act on, can make the fork body of target shift fork slide in the middle of second separation blade 5b and cushion 5c to because lateral friction drives second separation blade 5b and removes, thereby harm the rotatory air cylinder 5a that pushes down of second, so for avoiding above circumstances, third anchor clamps 6 act earlier than second anchor clamps 5.

Finishing polishing of one end face of the shifting fork, and polishing of the other end face of the shifting fork:

step one, loosening the second clamp 5: the second rotary pressing cylinder 5a drives the second baffle 5b to loosen the fork body of the target shifting fork.

Step two, loosening the third clamp 6: the cylinder 6b drives the second shift post 6a2 to move towards the first shift post 1a, and the second shift post 6a2 no longer abuts against the side of the target shift fork opening.

Step three: the servo system 7 drives the support plate 7a away from the target fork: the servo system 7 drives the support plate 7a to move downwards and away from the target shifting fork, so that the next step is prevented from being influenced.

Step four: the first gripper 1 is rotated to the designated position: the servo motor 4b drives the second gear 4c to rotate, the second gear 4c drives the first gear 4a to rotate, the first gear 4a is fixedly connected to the roller 2 to drive the roller 2 to rotate, and the first clamp 1 is fixedly arranged in the roller 2 to rotate along with the roller until the other end face of the target shifting fork is positioned on the working face of the milling machine 8; at the moment, the upper end face and the lower end face of the target shifting fork exchange identities.

Step five: and repeating the fifth step to the seventh step in the working step of polishing one end face of the fork opening of the target shifting fork.

Finishing polishing, and taking out the shifting fork:

Step three: loosening the first clamp 1: the first barrier post 1a drives the first barrier piece 1c to release the fork head of the target shift fork, so that the target shift fork is completely released.

Step four: and taking out the shifting fork.

All the working steps are the working steps of polishing the end face of the fork opening of one shifting fork, and the rest shifting forks can be continuously carried out by repeating the steps.

No matter whether the axis of the fork head of the shifting fork is vertical to the fork opening of the shifting fork or not, the operation steps are not influenced.
