【摘要】：为检测滚动直线导轨副滑块内滚道的位置、圆弧半径,提出了一种基于激光位移传感器测距的滑块内滚道的检测方法,该方法将激光位移传感器相对内轨道轴线以一定角度倾斜,通过扫描内滚道轮廓得出一个半椭圆轮廓,以最小二乘法进行椭圆拟合。通过数学分析,内滚道位置和半径大小可以转化为拟合椭圆的形心位置和椭圆的短轴长。通过对高精度圆柱做等效验证试验,验证了测量方案的可行性,最后进行了多方面的误差分析。
[Abstract]:In order to detect the position and arc radius of the inner raceway of the sliding block of the rolling linear guide rail, a method of detecting the inner raceway of the slider based on the laser displacement sensor is proposed. In this method, the laser displacement sensor is inclined to the axis of the inner orbit at a certain angle, and the semi-elliptical contour is obtained by scanning the inner raceway contour, and the ellipse fitting is carried out by the least square method. Through mathematical analysis, the position and radius of the inner raceway can be transformed into the centroid position of the fitting ellipse and the short axis length of the ellipse. The feasibility of the measurement scheme is verified by the equivalent verification test of the high precision cylinder. Finally, the error analysis is carried out in many aspects.
