摘　　要：为了保证大尺寸轴孔类零件的热装配质量,基于非合作式激光相位测距技术和曲线拟合技术,提出了一种针对大尺寸轴孔类零件热装配轴线位置测量和重合调整的方法,建立了轴孔类零件装配轴线的测量模型,给出了两装配轴线重合调整理论参数依据,并对轴线测量系统进行了误差分析,最后运用Matlab对利用该测量方法采集的装配轴线的可靠性进行了仿真验证。验证结果表明:利用该测量方法得到的轴线在一定条件下可以作为被测轴孔类零件的理想轴线。To ensure the quality of the hot assembly for the large-size axis and hole parts,based on non-cooperative laser phase distance measuring technology and curve fitting technique,a method of measurvment and adjustment was proposed for the hot assembly axis-line position of the large-size axis and hole parts,and the measurement assembly axis model of the axis and hole parts was founded,the assembly parameters was given according to the axis adjustment theory,and then the error of the measurement system was analyzed.Finally using Matlab with the measurement method to the simulation verification have been carried out to the reliability of the axis assembly.The verification results show that the axis-line which was acquired by the method can be seen as the ideal axis of the measured axis and hole parts.
