为解决旋转工作台在装配过程中产生的安装误差,旋转轴与坐标测量机Z轴不平行,因而造成整体检测精度不够这一难题,提出了旋转轴空间位置参数标定的新方法:设计专用标定工装,通过找正和测量标定工装的基准面和基准孔特征要素,得到旋转轴所在空间直线方程,从而实现旋转轴空间位置参数的标定。实验结果表明该方法简单、高效,基于该工装的旋转轴空间参数标定方法与数据整合算法适合航空发动机叶片高精度的检测。
In order to solve the problem that the installation error of the rotary table during the assembly process is not parallel to the Z axis of the coordinate measuring machine, the overall detection accuracy is not enough. A new method for the calibration of the spatial position parameters of the rotary shaft is proposed: Tooling, by finding and measuring the calibration tooling datum and reference hole feature elements, get the rotary axis of the space where the line equation, so as to achieve the calibration of the spatial position of the rotary axis parameters. The experimental results show that the method is simple and efficient. Based on the tool calibration method and data integration method of rotating shaft space parameters, it is fit for the high precision detection of aeroengine blades.
