中文摘要:
      针对利用激光跟踪仪对数控加工中心进行线性测量成本过高的问题,开发了一种三维激光干涉球杆仪。利用激光干涉法实现距离测量,设计全新测量光路,并通过伸缩杆的被动拉伸实现跟随测量。采用双球铰运动副为激光器的空间姿态调整提供保证,并搭配激光器、镜组微调等装置实现随时对光。利用ANSYS Workbench软件对装置进行建模并验证模型精度。建立机构运动学方程,利用MATLAB对运动空间进行仿真。通过实验验证激光光路,证明了该设计的可行性。
英文摘要:
      Aimed at the high cost of linear measurement for CNC machining center by using laser tracker, a three dimensional laser interference double-ball-bar was developed. The laser interference method was used to measure the distance, a new measuring optical path was designed, and the following measurement was realized by the passive stretching of the extension rod. The double spherical joint motion pair was used to ensure the space attitude adjustment of the laser, and the laser, mirror group fine adjustment and other devices were used to realize beam focusing at any time. ANSYS Workbench software was used to model the device and verify the model accuracy. The kinematic equation of the mechanism was established, and the motion space was simulated by using MATLAB. The laser path was verified by experiments, and the feasibility of the design was proved.
