三轴相交度的一种测量方法

介绍一种通过激光跟踪仪测量三轴转台三轴相交度的测量方法。该测量方法是利用激光跟踪仪测量出转台内、中、外框上两固定点(靶镜座位置)绕其回转轴线运动时一些位置点的空间坐标,拟合这些点从而构造出两个圆及其圆心,再由两个圆心构造出一条回转轴线。这样,将三轴转台的三条回转轴线构造出来以后就可计算出三条回转轴线两两之间的距离,根据三条回转轴线两两之间的距离就能求出三轴转台的三轴相交度。

A three-axis Intersecting Degree Measurement

A measurement method of three-axis turntable ＇ s axis intersecting degree is described.The measurement method is the use of laser tracker to measure the turntable,the two fixed points on the frame（the target mirror seat position） around the rotation axis of movement of some of the space coordinates of the point where the fit of these points to construct two circles and its center,and then construct a circle by the two rotary axes.Thus,the rotation axis of the three-axis turntable constructed after three rotary as can be calculated the distance between each,according to three rotary as the distance between any two three-axis can be calculated intersection degree of three-axis turntable.
