摘　　要：对激光校准仪测量双主轴镗铣机床同轴度误差进行了研究,根据双主轴镗铣机床结构特点,从立柱直线度、垂直度、定位精度三个主要方面分析对同轴度误差的影响。通过对同轴度误差测量结果分析,确定立柱的定位精度偏差方向、立柱对工作台垂直度偏差方向为主要影响因素,根据此结论,可有针对性地进行双主轴镗铣机床装配过程优化,降低同轴度误差。In this paper, the coaxiality error of dual-spindle boring and milling machine measured by laser calibrator is studied, and the error factors affecting the measurement results are analyzed. According to the structure characteristics of dual-spindle boring and milling machine, the influences on the coaxiality error are analyzed from three main aspects: column straightness, verticality, and positioning accuracy. Based on the analysis of coaxiality measurement results, it is determined that the direction of deviation of the positioning accuracy of the column and the direction of deviation of the verticality of the column to the table are the main influencing factors. Based on the analysis results, the assembly process of dual-spindle boring and milling machine can be optimized in a targeted manner to reduce the coaxiality error.
