Thin-walled shifting fork turning clamp

Abstract

The invention discloses a thin-walled shifting fork turning clamp, relates to the field of machining and in particular relates to the thin-walled shifting fork turning clamp which comprises a clamp main body, wherein the clamp main body is a cylindrical truncated cone; a plurality of stop dogs are arranged on one end surface of the clamp main body; two stop dogs are arranged on the clamp main body in parallel; each stop dog is connected with a bolt through a threaded hole; two cylindrical pins are also arranged on the clamp main body and are a center positioning pin and a limiting pin respectively; the center positioning pin and the stop dogs which are arranged in parallel with the center positioning pin are arranged on the circumference of a same circle; the center of the circle is coincided with the center of circle of the end surface of the clamp main body; threads are formed in the top end of the center positioning pin; and the top end of the center positioning pin is connected with a nut. The thin-walled shifting fork turning clamp has a simple structure, is convenient in operation, can well ensure the size, form and position accuracy when a workpiece is processed and improves the production efficiency.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a thin-wall fork turning fixture. Background technique [0002] The dial is an important part to realize the gear shifting of the gearbox. Due to its special shape, it is difficult to clamp and correct, and it is difficult to process, especially the shape is relatively complicated, the size and shape accuracy are high, and the wall thickness of the shift fork head It is difficult to guarantee the processing accuracy of such thin parts due to improper process methods or clamping deformation during processing, which will directly affect the gear performance of the gearbox. The main difficulties in processing the parts are as follows: ( 1) The structure of the part is relatively unique and the shape is complex. The structure of the part is relatively complicated. The inner hole, the two sides, the end face, the groove, the hole, and the two fork heads are processed and clamped, ...
