摘　　要：针对航空制造企业光面塞规大批量检定中存在的检定精度及效率低、人工操作烦琐等不足,提出一种基于机器视觉和激光测径相结合的光面塞规直径测量方法。由激光测径仪测量塞规直径,机器视觉模块同步检测塞规在测径仪光幕当中的姿态,并对测径仪测量值进行修正。同时,利用专用工装配合气浮运动机构实现多个塞规的自动切换及单个塞规的多位置自动测量。试验结果表明,该系统的重复测量标准差为0.16μm,与立光计测量值相比的绝对测量误差≤0.5μm,塞规单端测量时间≤45 s,能够满足生产中的常用光面塞规快速高精度检定要求。In order to address the shortcomings of low calibration accuracy and efficiency,as well as cumbersome manual operations,in the large-scale calibration of plug gauges in aviation manufacturing enterprises,a method for measuring the diameter of smooth plug gauges based on machine vision and laser caliper is proposed.The diameter of the gauge is measured by a laser caliper,and the machine vision module synchronously detects its posture in the light curtain,and corrects the measured values of the caliper.At the same time,the use of specialized tooling combined with an air flotation motion mechanism achieves automatic switching of multiple gauges and multi-position automatic measurement of a single plug gauge.The experimental results indicate that the repeated measurement standard deviation of the system is 0.16μm.Absolute measurement error is less than 0.5μm compared to the measured value of the vertical optical comparator.The measurement time for single end of the gauge is less than 45 s,which can meet the fast and high-precision verification requirements of commonly used plug gauges in production.
