【摘要】：针对焊接模拟器中焊枪的定位,设计了一种新型的焊枪定位系统.该定位系统在焊件上布置有感应线圈膜,基于电磁感应得以确定焊枪在工作平面上的投影坐标x和y值,应用光纤传感器测量焊枪与焊件的距离,并通过空间几何转换从而间接确定焊枪的z坐标,应用焊枪内置的三轴陀螺仪和三轴加速度传感器模块获得焊枪的姿态,最后根据空间位置关系推导出了熔池的位置和操作者的动作,从而完成了焊枪定位系统的设计.结果表明,该设计能够较好地满足了虚拟焊接模拟器焊枪定位精度和实时性的要求.
[Abstract]:Aiming at the positioning of welding torch in welding simulator, a new welding torch positioning system is designed, which has inductive coil film on the welding piece. Based on the electromagnetic induction, the projection coordinates x and y of the welding torch in the working plane can be determined. The distance between the welding torch and the welding piece is measured by using the optical fiber sensor, and the z coordinate of the welding torch is indirectly determined by the spatial geometric transformation. The attitude of the welding torch is obtained by using the three-axis gyroscope and the three-axis acceleration sensor module. Finally, the position of the weld pool and the action of the operator are deduced according to the spatial position relationship. The design of welding torch positioning system is completed, and the results show that the design can meet the requirements of precision and real-time of welding torch positioning in virtual welding simulator.
