摘　　要：为提高大型模锻压机中C形板的焊接、加工精度,在对现有测量方法分析的基础上,提出一种新的基于激光跟踪仪进行测量的测量方法,并设计出一种用于激光跟踪仪进行测量的专用工作台,专用工作台能够实现跟踪仪的水平位移、水平角度和俯仰角度的调整功能。同时对激光跟踪仪的测量原理进行了分析,通过专用工作台有效降低激光跟踪仪的转角误差,减小仪器的水平转动和垂直转动,从而有效降低了激光跟踪仪的测量误差。提升了C形板的装配精度,对提升大型模锻压机的寿命、功能和运行精度具有重要的现实意义。In order to improve the welding and machining accuracy of C-shaped plate in large die forging press,a new measurement method based on laser tracker is proposed based on the analysis of existing measurement methods,and a special working table for laser tracker measurement is designed.The special working table can realize the adjustment function of horizontal displacement,horizontal angle and pitch angle of the tracker.At the same time,the measurement principle of the laser tracker is analyzed.The rotation angle error of the laser tracker is effectively reduced through a special workbench,and the horizontal and vertical rotations of the instrument are reduced,thus effectively reducing the measurement error of the laser tracker.It has important practical significance to improve the life,function and operation accuracy of large die forging press by improving the assembly accuracy of C-shaped plate.
