摘要
基于激光位移传感器旋转,以回转轴线为基准,提出和验证了一种测量深孔零件直线度的方法。实验结果表明,在选用的激光位移传感器精度为±2 μm的情况下,该方法实现了圆孔直线度的在机测量,与三坐标测量机给出的相对真值对比,误差低于12%。该测量模型仅需机床主轴及其进给部件,易于实施。
Abstract
Based on the rotation of laser displacement sensor, and taking the rotating axis as measuring basis, one novel method for measuring the deep hole straightness is presented and also verified. The experimental results show that, with the precision of laser displacement sensor of ±2 μm, the on-line measurement of the hole straightness can be done with the proposed method. Compared with the relative true value offered by three-coordinate measuring machine, the error is less by 12%. The model just needs the spindle and the feed component of machine tool and can be implemented easily.
