Further perfect, turning block is cylindrical piece, and the outer surface for turning block is equipped with annular knurl.Here turning block is cylinder chief
Bank, the effect that the outer surface for turning block is annular knurl are to improve frictional force, turn block so as to preferably rotate, anti-rotation stop
It is dynamic to turn block and skid.
It is further perfect, gasket is installed on threaded rod one.Here the effect of gasket is to improve nut to press shift fork class half
Press area when finished work-piece, thus when pressing shift fork class semi-finished product, press it is more steady, more firm.
The utility model has the advantages that: the utility model smart structural design, rationally, shift fork class semi-finished product
On mounting hole be respectively installed at positioning column, then, shift fork class workpiece is compressed using gasket and nut, then, segmental arc
Side lean against locating notch, then using the rotary table briquetting on hold-down mechanism go compress segmental arc the other end, thus dial
Fork class workpiece is fixed, and then rotates shift fork class semi-finished product, is turned end face to be processed and inner circle to be processed using lathe tool
Cambered surface is worthy of popularization to improve efficiency, reduce cost.
