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。
Most of the lathe machining accuracy detection method error is large, laser tracker can solve this problem, therefore, proposed a laser tracker for lathe machining accuracy detection method. The principle of laser tracker’s accuracy detection is described. The calibration method of plane and end point is used to correct the positioning accuracy of the laser tracker and obtain the coordinates of the laser signal. Setting 4 to 6 lathe machining base points, using laser electrical signal tracking base point, fitting the coordinate values provided by the laser tracker built-in algorithm, obtaining the base point coordinates, obtaining the distance between the base point and the lathe machining target point, achieving the target point calibration, To detect the lathe machining accuracy. The experimental results show that laser tracker has the advantages of small error and high efficiency in the detection of lathe machining accuracy.
