【摘要】：大多数车床加工精度检测方法的误差偏大,激光跟踪仪可解决这一问题,为此,提出一种应用激光跟踪仪进行车床加工精度检测的方法。阐述了激光跟踪仪的精度检测原理,使用平面与端点相结合的校正方法,对其定位精度进行校正,获取激光电信号坐标。设置4到6个车床加工基点,使用激光电信号跟踪基点,拟合激光跟踪仪内置算法提供的坐标值,获取基点坐标,求得基点与车床加工目标点之间的距离,实现目标点标定,以检测车床加工精度。实验结果说明,激光跟踪仪在车床加工精度检测中误差小且效率高。
[Abstract]:The error of most testing methods of lathe machining accuracy is too large. The laser tracker can solve this problem. This paper presents a method of measuring the machining accuracy of lathe by using laser tracker. The principle of precision detection of laser tracker is expounded, and the positioning accuracy is corrected by using the method of combining plane and end point. Get the coordinates of laser signal. Set 4 to 6 lathe machining base points, use laser signal to track base points, fit the coordinate value provided by the built-in algorithm of laser tracker, get the coordinate of base point. The distance between the base point and the machining target point of the lathe is obtained and the calibration of the target point is realized in order to detect the machining accuracy of the lathe. The experimental results show that the laser tracker has small error and high efficiency in detecting the lathe machining accuracy.
