摘要
运用半径增量法，建立了大型轴类零件同轴度误差的最小二乘法和最小条件法两种评定方法的实用数学模型。介绍了采用微机控制的大型轴类零件同轴度误差数据采集与数据处理系统的组成。在ＳＴＤ工业控制机的控制下，系统可自动实现测头调零、数据采集、数据处理、测量结果显示和（或）打印。运用该系统对工件进行了实际测量。实测结果表明：该系统安装调试方便，抗干扰能力强，测量速度和测量精度均较高。在车间条件下，既适用于加工中的大型轴类零件同轴度误差的在机测量，也适用于处于正常使用安装位置的大型轴类零件的在位测量。
Using the radialdeviation method, the practical mathematical models of least square and minimum condition evaluation method of coaxality error of large dimension shaft were established. The structure and working principles of the system were introduced also. Under the control of an industrial computer, the system can automatically execute the works of zero adjustment of measuring transducer, collecting and processing the measured data, displaying and/or printing the measurement results. The coaxality errors of three workpieces were measured. The measurement results indicate that the system is assembled and adjusted conveniently, and has stronger antijamming ablility, higher measurement speed and higher measurement accuracy. On the workshop conditions, the system can be applied to in situ measurement of a large dimension shaft being worked on a machine tool, and it can be also used in measuring a large dimension shaft installed properly in equipment.
