针对高精密计量用标准镜头对中心偏差的严格要求，提出一种车削加工与计算机辅助装调相结合的高精度定心装调技术。通过车削定心对各镜组光轴的倾斜误差进行初步控制，然后结合高精度中心偏差测量仪对平移偏差进行“逐片”调校。利用计算机模拟光轴空间状态的方法，精确定量修磨平行隔圈成一定楔角，进一步控制各镜组间的倾斜误差。结果表明：运用该技术定心后，标准镜头各镜组间的倾斜偏差≤5″，平移误差≤3μm，定心精度满足设计指标。%A new high‐precision assembly technique by combining traditional turnery technique with computer assisted assembly ,in an attempt to meet the strict requirements on centering er‐rors of high‐precision standard lens ,was introduced .First ,the tilt‐errors of optical axes were managed by turning centering initially ,and then with the assistance of high‐precision centering errors measurement ,shift‐error alignment for each lens was conducted .Last ,through simula‐ting the optical axis space state by computer ,the ration abrade for circle was done precisely at given angle so as to control the tilt‐error between each lens .The result indicates that by using this technology ,the tilt‐error of the lens is less than 5″and the shift‐error is within 3μm ,thus the design objectives are met .
