针对滚动直线导轨副精度保持性检测要求，提出了一种基于激光位移传感器测距的滚动直线导轨副运动精度在线检测方法。根据相对运动定理，该方法将4个激光位移传感器在线测量的滑块相对导轨基准的距离变化量转化成导轨平行度和滑块偏转角的变化量。通过滚动直线导轨副精度保持性测试方法，在线测量滚动直线导轨副在实际运行过程中的精度损失量，并与滚动直线导轨副的离线数据对比，有效验证了测试原理的可行性。最后，从多方面进行了误差分析。
Abstract
According to the testing demands of precision maintenance for linear rolling guide, a online testing method for measuring the motion accuracy based on laser displacement sensor was presented. The proposed method applied one kind of conversion, which makes the variation on distance of linear rolling guide tested online by laser displacement measurement sensor turning into the variation on depth of parallelism and angle of deflection on the basis of relative motion theorem. Then the online loss of precision of linear rolling guide in actual running process was measured with the linear rolling guide movement precision measurement method, and the feasibility of testing principle was validated effectively through the comparison with the off-line data. Finally, error analysis was carried out from various aspects.
