Coaxiality detection and regulation method

Abstract

The invention discloses a coaxiality detection and regulation method, which comprises the following steps of code scanning, positioning, coaxiality measurement, coaxiality regulation, coaxiality secondary measurement, qualification judgment, screw tightening, measurement after the screwing, assembly qualification judgment and completion. The quantitative regulation is performed through an image measuring instrument; the automatic measurement and the automatic regulation of the coaxiality of assembled components are realized; the precision degree, the reliability and the like of the coaxialitymeasurement and coaxiality regulation are obviously superior to the precision degree, the reliability and the like of an original measurement and regulation method; the assembly quality can be effectively improved; the assembly efficiency is improved; after the assembly, the rework rate of workpieces is greatly reduced.

Description

technical field [0001] The invention belongs to processing and assembling methods, in particular to a coaxiality detection and adjustment method. Background technique [0002] Coaxiality is a positioning tolerance, and the theoretically correct position is the reference axis. Since the difference between the measured axis and the reference axis may appear in all directions in space, the tolerance zone is a cylinder whose axis is the reference axis, and the tolerance value is the diameter of the cylinder. [0003] At present, when assembling disc-shaped parts and cylindrical parts, it is often necessary to limit the coaxiality of the specified hole in the disc-shaped part and the specified outer circle in the cylindrical part, and ensure the coaxiality value after fixing within the specified range. [0004] However, in the current part assembly process, the adjustment, positioning, and fixing of the coaxiality are entirely based on operating experience, which cannot be quan...

Problems solved by technology

[0004] However, in the current part assembly process, the adjustment, positioning, and fixing of the coaxiality are entirely based on operating experience, which cannot be quantified and precisely adjusted, resulting in high rework rates and high labor intensity.
