Multifunctional positioning tool for automobile part machining

Abstract

The invention relates to a multifunctional positioning tool for automobile part machining. The multifunctional positioning tool comprises a flange plate, a transmission shaft and an air ring, a bearing is embedded in the flange plate, the transmission shaft is assembled in the flange plate through the bearing, a butt joint base is arranged on the right side of the transmission shaft, and a tool chuck is installed at the right end of the butt joint base through a bolt; the positioning tool is fixed to the right wall face of a machining lathe gearbox through the flange plate, the left end of the transmission shaft is fixedly connected with a driving shaft in the gearbox, so that the transmission shaft can drive the butt joint base and the tool chuck to rotate synchronously, and when a blocking base rotates along with the chuck, the air ring is forced to extrude leftwards and exhaust air outwards, and the exhausted gas is sprayed on the chuck through a gas pipe, so that granular fine waste falling into a gap of the chuck is sprayed outwards in the machining process, the functionality is improved, the tool chuck can be cleaned at the same time in a rotating state, the application effect is better, a machine tool safety door can also be used when being closed in the machining process, and the structure is more reasonable.

Description

technical field [0001] The invention relates to the technical field of machining positioning tooling, in particular to a multifunctional positioning tooling for auto parts processing. Background technique [0002] Machining lathe equipment is composed of gearbox, bed, tailstock and cooling system, etc. The core part is the gearbox, which is equipped with speed change gear, spindle and spindle motor, etc. During the machining process of the blank, it needs to be clamped The tooling fixes it on the transmission shaft, and the transmission shaft is driven by the main shaft in the gearbox to rotate with the workpiece, and is circumscribed by the tool rest on the bed. [0003] The above-mentioned machining tooling used to clamp the workpiece is also called positioning tooling, which is designed according to the shape of the part, such as special-shaped tooling, etc., and the shaft parts are regular in shape, so the machine tool chuck used to clamp the shaft parts can also be call...

AI Technical Summary

Problems solved by technology

[0004] After the workpiece clamped by the chuck is processed, waste particles will be left in the chuck. During the finishing process, because the waste particles are small, it is not easy to clean such waste into the chuck cavity or chuck lock gap. The transmission air pump cleaning method also needs to add an air compressor in the workshop, the installation cost is high, and it takes up a lot of space. Manual cleaning with a brush is not thorough and will waste labor.
