Abstract

The invention discloses a quick clamping system for reverse gear shifting cantilevers. The quick clamping system comprises a bottom plate and four quick clamping components which are sequentially arranged on the bottom plate at intervals and side by side from left to right. Two locating shafts on each workpiece locating block are inserted into corresponding mounting holes in a workpiece. Hard alloy blocks are welded to each slope of the V-shaped opening of each V-shaped locating block, and each workpiece is pressed from the left side and the right side of the rear portion of the workpiece respectively. Oil hydraulic rotating cylinders drive pressing plates to rotate to enable the ends of the pressing plates to press the upper end faces of the rear right sides of the workpieces. Locking screw rods horizontally and obliquely penetrate through locking fixing blocks and then abut against the front left walls of the workpieces. Executing ends of lever type oil hydraulic cylinders abut against the centers of the front portions of the workpieces. The cantilever ends of the workpieces are clamped by limiting fixing blocks and elastic propping mechanisms. The quick clamping system for the reverse gear shifting cantilevers is applied to a vertical machining center and can be used for quickly and precisely clamping and locating the workpieces; the four quick clamping components are operated by one person, and the number of fixtures and the frequency of clamping are reduced, so that work efficiency is improved, and labor cost is lowered.

Description

technical field [0001] The invention relates to a processing fixture for parts of a transmission, in particular to a cantilever end face 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 present invention aims to provide a cantilever milling end clamp for reverse gear shifting specially used in vertical machining centers. After the clamping is completed, it will be processed by the vertical machining center to replace CNC lathes, honing machines, and vertical drilling machines in traditional processin...
