Abstract

The invention discloses a clamp for milling of reverse-gear shifting cantilevers. Two positioning shafts on a workpiece positioning block are inserted into corresponding installing holes in a workpiece; hard alloy blocks are welded to both the bevels of the V-shaped opening of a V-shaped positioning block respectively so as to tightly press the workpiece from the left side and the right side of the rear of the workpiece; an oil pressure angle cylinder drives a press plate to rotate so that the end of the press plate can be pressed on the upper end face at the rear right side of the workpiece; a locking threaded rod horizontally penetrates through a locking fixing block in an inclined manner, and then abuts against the front left wall of the workpiece; the actuating end of a lever type oil cylinder abuts against the center of the front of the workpiece; the cantilever end of the workpiece is tightly clamped by a limiting fixing block and an elastic ejecting mechanism. When the clamp for milling of reverse-gear shifting cantilevers is applied to a vertical machining center, the clamp can tightly clamp and position the workpiece rapidly and accurately, the number of clamps and the clamping frequency are reduced, working efficiency is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a processing fixture for transmission parts, in particular to a cantilever milling fixture for reverse gear shifting. Background technique [0002] The processing of the reverse gear shift cantilever needs to go through multiple processes, including processing on CNC lathes, honing machines, and vertical drilling machines. The existing problems are: many times of clamping, long circulation time, easy to cause repeated positioning errors and bump damage ;Each process requires one person to operate, and requires the cooperation of multiple operators to complete. Contents of the invention [0003] The purpose of the present invention is to provide a cantilever milling fixture for reverse gear shifting specially used in vertical machining centers, which can be processed by the vertical machining center after the clamping is completed, so as to replace CNC lathes, honing machines, and vertical drilling machines in traditional proc...
