激光跟踪仪校准技术及在机床检测中的应用

Calibration of laser tracker and its application in detection of machining tool

讨论了激光跟踪仪的校准技术,分析了测量误差来源及误差对跟踪仪产生的影响,并利用三坐标测量机对激光跟踪仪进行了校准。结合生产需要,利用激光跟踪仪高效地对大型机床进行检测,制定了激光跟踪仪检测大型机床的方法。结果显示,利用激光跟踪仪能够精确地、高效地对机床进行检测,并指导工人对机床进行维护和调整。研究结果表明,激光跟踪仪不仅能对现场的机床进行精度检测,而且能对不易搬动的零部件、生产线以及夹具等进行测量。

Calibration method for laser tracker was discussed and error sources were anlyzed. Calibration was carried on by use of CMM. Laser tracker was used to detect large-scale machining tool. Then the measuring method was described detailedly. The result shows the machining tool can be checked precisely and high effiently by laser tracker. The paper also shows both the machining tools and other large-scale objects, such as assembly line and jig, can be measured by laser tracker.
