摘　　要：为了提高涡旋压缩机的加工精度和啮合性能,在圆柱度测量仪的基础上开发快速测量实验平台,建立测量系统误差模型.通过对径向误差模型优化迭代计算出总的偏差,并由总的偏差和测量偏差得到涡旋体加工位置偏差;最后,通过三坐标测量机对测量结果进行对比分析.结果表明,测量时间由原来的20 min缩短到180 s.在满足测量精度的前提下,快速测量系统能满足涡旋体在线加工的测量环境和测量时间,能快速补偿加工位置偏差,提高涡旋体加工精度.In order to improve the machining accuracy and fitting performance of the scroll profiles,a novel rapid measurement system of machining deviation was developed based on a cylindricity meter and its error model was established.The total error was obtained through the optimization computation of the radial error model and then the machining error of the scroll profiles was got by the total error and measurement error.Finally,the new system was compared with the coordinate measurement machine（CMM）.The experimental results shown that the measurement time of the new system was 3 minutes but that of the CMM was 20 minutes.Under the condition of the demanded measurement precision,the novel measurement system can meet the requirements for measurement environment and time of the on-line manufacture for the scroll profiles through rapidly compensating the deviation of the machining position which can improve the machining accuracy of the scroll profiles.
