基于非接触式光学的复合齿轮轴同轴度测量系统研究
Study on Coaxiality Measurement System of Compound Gear Shaft Based on Non?contact Optic
摘要
Abstract
Aiming at the shortcomings of traditional contact measurement methods such as low measurement efficiency, high cost and low accuracy,a non-contact optical measurement method based on the laser displacement sensor is proposed. According to the relevant regulations of the coaxiality error evaluation standard and the structural characteristics of the compound gear shaft,we have designed and built a set of supporting software system as well as a hardware test platform. In this paper,the distance difference threshold and scale threshold methods are used to eliminate outlier data. The least squares circle is selected to calculate the center of the circle and the minimum containment cylinder axis method is used as the reference axis of the composite gear shaft. Compensated by the standard step shaft calibration,the coaxiality error of the composite gear shaft can be measured to be within 0.01 mm in less than two minutes. The range value of the multi-section measurement test is 0.065 mm. The average coaxiality error is?0.476 mm.关键词
