Grinding pin fixture for steering gear valve sleeve.

The technical scheme of the utility model is:

A power steering valve sleeve grinding pin fixture, which is composed of a bottom plate, a V-shaped block, a positioning key block, a pressing block, a positioning block and a locking device for the pressing block; The screw is movable with a pressing block, the bottom plate on one side of the positioning block is fixed with a V-shaped block, the top of the V-shaped block is provided with a chute, and a positioning key block is movably installed in the chute, and the bottom plate on the other side of the positioning block is installed. There is a pressing block locking device; the pressing block locking device is connected with the pressing block in sliding contact.

The locking device of the pressing block is composed of a bushing and an eccentric wheel; the eccentric wheel is movably mounted on the bottom plate through the shaft screw and the bushing, and the eccentric wheel is provided with a handle.

A compression spring is arranged between the positioning block and the pressing block.

The section of the pressing block is 7-shaped, the end of the pressing block is provided with a V-shaped mouth corresponding to the V-shaped block, and the central part of the pressing block is provided with a slide hole matched with a fastening screw.

The two ends of the bottom plate are respectively provided with assembly ports.

The practical advantage of the present invention is:

The pin grinding fixture for the power steering gear valve sleeve has a simple structure and is easy to operate. During work, the steering gear valve sleeve grinding pin fixture is fixedly installed on the processing platform of the processing machine tool. Put the workpiece to be processed into the workpiece position between the V-shaped block and the pressing block, rotate the workpiece and push the positioning key block, so that the positioning key block positions the grinding pin groove of the power steering gear valve sleeve. Then rotate the eccentric wheel, and the pressing block cooperates with the V-shaped block under the action of the eccentric wheel to fix and clamp the workpiece. After the workpiece is processed on the processing machine tool. Rotate the eccentric to keep the eccentric away from the compression block. Under the action of the compression spring, the pressing block is automatically out of contact with the workpiece and withdraws from the positioning key block. The workpiece is taken out to enter the next processing cycle. The pin grinding fixture for the power steering gear valve sleeve has a simple structure and stable processing quality. It solves the problems of high investment cost and difficult equipment maintenance in the existing automatic processing method, as well as the low efficiency and complicated operation of the manual method, reduces the labor intensity of workers, and improves work efficiency. It is especially suitable for the processing of power steering valve sleeve pin grooves use.
