本文提出了一种测量高精度箱体孔系同轴度的方法．它是将装有电感测头的测棒 支承在两球顶尖间，用以代替精密回转轴系，测出诸孔的形状及位置误差信息后，藉 助于微型电子计算机进行数据处理．求得孔系的同轴度误差。该方法及其装置测量精 度高，可达微米级，结构简单，操作方便，对环境无苛刻要求，适宜在生产线上使 用。
In this paper, a method of measuring the coaxiality of high accuracy box hole series is proposed. It is equipped with an inductive probe head mounted on the ball between the two centers, instead of precision rotary shaft system, measured the shape and position of the hole error information, with the help of a microcomputer for data processing. Obtained hole Department of coaxial error. The method and the device thereof have the advantages of high measuring precision, up to the micron scale, simple structure, convenient operation, no strict requirement on the environment and suitable for use in the production line.
