摘　　要：针对飞行器结构装配过程中孔的垂直度测量存在效率低、工具精度低等问题,从大规模、快速生产和低成本的实际需求出发,结合机械电子技术、接触式测量方法和最小二乘拟合方法提出孔垂直度轴线偏差测量法,设计表面孔垂直度快速检测仪,并对其测量结果开展测量不确定度评定、测量系统分析和对比实验测试。结果表明:测量结果分散性较小;测量系统稳定可靠;与三坐标测量机相比,在95%的置信区间,两种设备测量差值为0.0212°。To address the low efficiency and poor tool accuracy in the verticality measurement of holes in the process of aircraft structure assembly,by combining mechanical and electronic technogy,contact measurement method and least square fitting method,proposes the measurement method of hole perpendicularity axis deviation in the light of actual needs of large-scale,rapid production and low cost.The surface perpendicularity rapid detector is designed,and the measurement uncertainty evaluation,measurement system analysis and comparative experimental test on the measurement results are carried out.The results show that the dispersion of measurement results is small,the measuring system is stable and reliable,and the difference between the two devices is 0.0212 degrees with a 95%confidence interval in comparison with the CMM.
