A compact cantilever combination clamping mechanism for reverse gear shifting

Abstract

The invention discloses a compact type gear reversing and shifting cantilever combined clamping mechanism. The compact type gear reversing and shifting cantilever combined clamping mechanism comprises a bottom plate, a positioning base, a positioning base supporting block, a first clamping mechanism, a shared pressing mechanism and a second clamping mechanism. The first clamping mechanism comprises a workpiece installation block, a V-shaped positioning block, a limiting fixing block, an elastic ejecting mechanism, a locking and fixing block, a lever type oil hydraulic cylinder and a locking threaded rod. The second clamping mechanism and the first clamping mechanism are of the completely same structure. The second clamping mechanism is installed after rotating by 180 degrees relative to the first clamping mechanism. The shared pressing mechanism comprises an oil hydraulic swing clamp cylinder and a pressing plate. Semicircular notches are formed in the two ends of the pressing plate. Workpieces can be rapidly and accurately clamped and positioned when the compact type gear reversing and shifting cantilever combined clamping mechanism is applied to a vertical machining center; and the two clamping mechanisms are operated by one person, so that the number of clamps and the number of clamping times are decreased, the work efficiency is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a processing fixture for parts of a transmission, in particular to a cantilever combination clamping mechanism 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 combination clamping mechanism for reverse gear shifting. After the clamping is completed, the vertical machining center can be used to replace the machining done by the CNC lathe, honing machine, and vertical drilling machine in the traditional machining process, s...
