摘要
丝杠是工业生产中重要的传动部件,其自身精度往往对整个系统的精度起着决定作用。因此,丝杠螺旋线误差的测量有着重要实际价值。针对目前丝杠螺旋线误差检测系统的不足,对以往的测量方法进行了改近,设计了以双频激光干涉仪作为长度测量的标准,以圆光栅作为转动角度的测量的标准,数据处理上利用可编程逻辑器件(CPLD)为核心电路的计算机测量方案。在此基础上,进行了样机实验研究和试运行,运行结果证明,测量系统能够实现2级以上丝杠螺旋线误差的动态测量,具有测量效率较高,能够对环境造成的偏差进行补偿的特点。
Screw shaft is important transmis-sion components in industry and it plays a decisive role to the precision in the whole system,there-fore,the detection precision of screw shaft has extremely important practical value.In view of the current shortage of detection system of screw shaft detection system,it design a scheme with the con-ventional modified measurement method,the dual frequency laser interferometer as the length of measurement standards,the circular grating as a standard measurement of the rotation angle and the data processing by using programmable logic device （CPLD）as the core circuit.On the basis of this, experiments and test running are carried out to study the prototype,the running results show that the dynamic measurement system can achieve more than level 2 screw shaft and has a feature of high measurement efficiency,the deviation compensation caused by the environment.
