Therefore, there is a strong practical demand in the manufacturing process control and component testing process.
目前端面凸出量主要有两种检测方式：At present, there are mainly two detection methods for end surface protrusion:
（1）平台+辅助检具：在检测平台上放置专用的可调整辅助检具，挺柱放置于辅助检具上，通过测高仪及调整辅助检具，挺柱顶面三点校平，利用测高仪测量最高点到基准圆的高度差，即为凸出量；(1) Platform + auxiliary inspection tool: place a special adjustable auxiliary inspection tool on the inspection platform, and place the tappet on the auxiliary inspection tool. Through the altimeter and the adjustment of the auxiliary inspection tool, the top surface of the tappet is leveled at three points. Use the altimeter to measure the height difference from the highest point to the reference circle, which is the amount of protrusion;
（2）三坐标：按图纸要求测量基准圆作为基准投影平面，对顶面中心多点测量，计算点到面的距离，取最大值为凸出量。(2) Three coordinates: measure the reference circle as the reference projection plane according to the requirements of the drawings, measure the center of the top surface at multiple points, calculate the distance from the point to the surface, and take the maximum value as the protrusion.

（2）测量效率低：测量时间长，测量过程复杂、繁琐。平台检测方式，熟练技术工人需要5~8分钟/件，在完成调整后三坐标检测平均2~3分钟/件；(2) Low measurement efficiency: the measurement time is long, and the measurement process is complicated and cumbersome. For the platform detection method, it takes 5-8 minutes per piece for skilled workers, and the three-coordinate detection averages 2-3 minutes per piece after the adjustment is completed;
（3）测量稳定性差：平台检测的测量精度由于受到平台精度、平面调整的技能、目测最高点位置不准确及基准圆校平等多个环节的影响，测量精度不高、稳定性差，三坐标由于存在基准投影平面误差的影响，测量精度同样不高；(3) Poor measurement stability: The measurement accuracy of platform detection is affected by multiple links such as platform accuracy, plane adjustment skills, inaccurate visual position of the highest point, and reference circle calibration. The measurement accuracy is not high and the stability is poor. The three coordinates are due to There is the influence of the reference projection plane error, and the measurement accuracy is also not high;
（4）测量成本大：平台检测、三坐标检测投资均较大、检测场地需要占用大量的空间，同时需要配备专业检测人员。(4) The cost of measurement is high: the investment of platform detection and three-coordinate detection is relatively large, the detection site needs to occupy a lot of space, and professional detection personnel are required.
