针对高能同步辐射光源需要进行大批量磁铁的中心引出标定,提出了一种基于三坐标测量机的磁铁机械中心标定方案,确定了编写自动测量程序的流程和方法 ,参与完成了加速器中多种类型磁铁的标定。对176块储存环六极铁的三坐标机测量数据进行分析,结果表明:每块磁铁进行两遍机械中心标定,获得准直基准点的标定重复性在0.01 mm之内;极缝间距离的实测值与设计值标准偏差均在0.015 mm之内;标定效率相较激光跟踪仪提高了2倍。这种借助三坐标测量机的磁铁标定方法可以提高标定精度,降低人力成本,提高工作效率,能为加速器工程中磁铁中心的引出标定工作提供参考,保证加速器装置的安装顺利,满足加速器准直测量的工程进度要求。

Aiming at the High Energy Photon Source which needs to calibrate the center of a large number of magnets,a scheme of calibrating the center of magnetic machinery based on coordinate measuring machine(CMM)is proposed,the process and method of writing automatic measuring program are determined,and the calibration of various types of magnets in the accelerator is completed.The results show that the calibration repeatability of the reference point of collimation is within 0.01 mm by calibrating the mechanical center twice for each magnet.The standard deviation between the measured value and the design value is within 0.015 mm.The calibration efficiency is 2 times higher than that of the laser tracker.This method of magnet calibration with CMM can improve the calibration accuracy,reduce the labor cost,improve the work efficiency,provide reference for the magnet center extraction calibration in the accelerator work,ensure the smooth installation of the accelerator device,and meet the requirements of the accelerator alignment measurement project schedule.
