摘要

摘要: 回转轴线的标定技术是保证θFXZ型测量机测量精度的一项关键技术。针对该型测量机没有y方向运动的特点,分析了其内外径测量原理,讨论了回转轴线标定误差与内外径测量误差的关系,并提出了一种基于环形标准件内孔、外圆的测量结果,快速标定回转轴线的方法。试验结果表明:利用该方法进行θFXZ型测量机的回转轴线标定,标定后,测量机对其它型号环形标准件的测量误差在±0.001 mm以内。该方法实现了对回转轴线的精确标定,同时操作简单,可以制定标定软件,实现回转轴线的软件自动标定。

Abstract: θFXZ measuring machine. Considering that there is not motion in y direction for this type measuring machine, the measurement principles of inner and outer diameters have been analyzed. Moreover, the relationship between the calibration error of rotary axis and the measurement errors of inner and outer diameters has been discussed. Then a fast calibration method of rotation axis has been proposed, and it is based on the measurement results of inner hole and outer circle in the standard ring. The experimental results indicate that measurement errors of the other standard rings are in the range of ±0.001 mm after calibrating the rotary axis with the present technique. This aforementioned calibration technique is able to achieve the calibration accuracy of the rotary axis. Besides, it is easy to implement the software, and the computer software can be developed to fulfill automatic calibration of the rotary axis.
