AI Technical Summary

Technical Problem

The existing auxiliary tooling cannot complete the inspection of all machining features of the gearbox housing in one go, and requires loading and unloading twice, resulting in a long inspection time. It is also not suitable for clamping the gearbox housing.

Method used

An auxiliary tooling is designed, which includes a base, a fixed column, a rotating unit, a vertically adjustable limit unit and a horizontally adjustable limit unit. The rotating unit and the limit unit are used to realize the initial positioning and state adjustment of the gearbox housing, thereby reducing the number of assembly and disassembly times.

Benefits of technology

All machining features of the gearbox housing can be inspected at one time, saving inspection time, improving inspection efficiency and stability, and preventing damage caused by large-scale rotation of the rotating unit during the inspection process.

Abstract

The utility model provides an auxiliary tool for three-coordinate detection, which can solve the problems that when a gearbox shell is detected, an existing tool cannot detect all machining characteristics at a time, needs to be assembled and disassembled twice, or is not suitable for clamping the gearbox shell. The tool comprises a base, a fixed stand column, a rotating unit, a vertical adjustable limiting unit and a horizontal adjustable limiting unit, the rotating unit comprises a bottom plate provided with a first positioning check block, a first stand column and a second stand column, and the two opposite side walls of the first stand column are provided with a second positioning check block and a first locking piece; the two opposite side walls of the second stand column are provided with a third positioning check block and a second locking piece, the first positioning check block, the second positioning check block and the third positioning check block are used for abutting against one end face of the gearbox shell to be detected, and the first locking piece and the second locking piece are used for abutting against the other end face of the gearbox shell to be detected. One end of the vertical adjustable limiting unit is movably connected with one fixed column, and the other end abuts against the first column or the second column.
