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.
Aimed at the positioning of the welding torch in the welding simulator,one new positioning system was designed.In this system,the coil film was put on the welding plate,so that the welding torch＇s X and Y coordinates projections in the welding plate could be got. The Z coordinate could be captured by optical fiber sensor indirectly,and the posture of welding torch was captured by a 3-axis gyro and a 3-axis accelerometer,and then the weld pool ＇s position and the trainee ＇s action could be gained according to the geometric relationship. The results shows that,this kind of design could meet the requirement of welding simulator＇s real-time and accuracy.
