中文摘要：
基于光电原理,提出了一种利用输出电压的变化规律来准确测量深孔直线度的方法。分析了光电探测器发生平移运动和旋转运动时造成的实际孔心的变化规律。基于最小二乘原理,推导了深孔直线度与输出电压的关系,为深孔直线度光电测量提供了理论基础。利用光电测量原理,设计了一种具有自定位功能、实时显示深孔直线度误差的光电测量装置,可实现深孔直线度的无损自动检测。
英文摘要：
Based on the photoelectric principle,an accurate method to measure the deep hole straightness is built according to the changing rule of the output voltage. The changing rule of the actual hole center is analyzed when the photodetector has translational and rotational movements. Based on the least squares principle,the relationship between the deep hole straightness and the output voltage is deduced,which provides the theoretical foundation for deep hole straightness photoelectric measurement. According to the photoelectric measurement theory,a self-positioning,real-time display device of deep hole straightness measurement deviation is designed,which can effectively achieve automatic and non-destructive detection of deep hole straightness measurement.
