Clamp for drilling of shifting fork

Abstract

The invention provides a clamp for drilling of a shifting fork, and belongs to the technical field of machining. The clamp comprises a compressing assembly, a locating assembly and a threaded hole guide assembly. A plug of the locating assembly penetrates a bearing support, and the rear end of the plug is arranged on the bearing support through a plug nut. An anti-rotation block is arranged between the inner end faces of two feet of the shifting fork. The lower end of a compressing plate bearing column of the compressing assembly is arranged on the bearing support, the upper end of the compressing plate bearing column abuts against one side of a compressing plate, and the other side of the compressing plate is pressed on the shifting fork. The lower end of a compressing adjusting rod is arranged on the bearing support, and the upper end of the compressing adjusting rod penetrates a U-type groove of the compressing plate and is locked by a compressing locking nut. A guide bearing plate of the threaded hole guide assembly is horizontally arranged on the upper side of the bearing support through bearing plate mounting screws. A guide sleeve is arranged in a clamping groove and compressed on the guide bearing plate through a guide sleeve mounting screw. The clamp is good in clamping effect, and the accuracy of the position of a threaded hole and drilling quality are improved through the threaded hole guide assembly.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a clamp for drilling holes of a shift fork. Background technique [0002] The shift fork is an important part of the car, its main function is to toggle slipping gear , changing its in gear shaft The upper position can be moved up and down or left and right to achieve different speeds. or mechanical products clutch The control, such as the structure of the end face combined teeth, the structure of the inner and outer teeth, all need to use a fork to control a part of it to realize the combination and separation. The shift fork is set on the shaft by the installation hole, and is positioned with the shaft by the fastening screw. The shift fork foot is stuck in the shaft of the double gear, and the speed change operating mechanism drives the shift fork and The shafts slide together in the gearbox so that the transmission shifts gears. Both sides of the mounting...

AI Technical Summary

Problems solved by technology

Both sides of the mounting hole need to be processed for threaded holes for mounting screws. At present, the commonly used fixture for processing threaded holes is a vise. The vise directly clamps the shift fork and installs it on the drilling machine. However, this clamping method is very inconvenient. Stable, the fork will move or jump during processing, which will affect the quality of drilling and easily lead to deformation of the clamping part after processing

Moreover, there is no guiding structure for threaded hole processing, which may easily cause inaccurate threaded hole positions and easy drilling of threaded holes
