摘要： 由于机床具有质量大且不易移动的特点，因此对其竖直定位面位置误差进行现场测量一直是个难题.为此，设计了可以现场测量竖直平行面位置关系的检测机构.该检测机构可以利用自身与平行平面形状轮廓间的几何关系，将已知基准平面形状轮廓分离，从而计算出被测平面的形状轮廓.依据计算出的形状轮廓与已知被测平面形状轮廓间的差异，可以确定两平行平面的位置关系.同时介绍了检测机构原理，给出了检测方案，开发了位置关系描述算法，并进行了测量试验.试验结果表明:该检测机构能够准确获得两竖直平行平面的位置关系.

Abstract: Because the machine tool is characterized by large mass and difficulty in moving， it is always a difficult problem to measure the position error of its vertical positioning surface on the spot. Therefore， a detection mechanism is designed which can measure the position relationship of the vertical parallel planes in the field. The detection mechanism can use the geometric relationship between itself and the parallel plane’s shape contour to separate the known datum plane’s shape profile， and the calculated shape profile of the measured plane can be thus obtained. According to the difference between the calculated shape profile and the known measured plane shape profile， the position relationship between the two parallel planes can be determined. Meanwhile， the principle of the detection mechanism is introduced， the detection scheme is given， the algorithm for describing the position relationship is developed， and the measurement test is carried out. The experimental results show that the detection mechanism can accurately obtain the position relationship between the two vertical parallel planes.

Key words: position relationship, on-line measurement, shape profile, detection mechanism, vertical parallel planes
