摘要
对矿用自卸车纵梁的焊接变形进行了分析研究。通过采用组对工装、控制焊接顺序和预热温度,以及利用FANUC机器人接触寻位、多层多道焊和电弧跟踪功能规划了一套车架纵梁的焊接路径,将焊接变形控制在5 mm以内,解决了长期以来焊接变形达10 mm的问题。该方法减轻了工人的劳动强度,提高了焊接效率,降低了焊接返修成本,保证了生产质量。
The welding deformation of longitudinal beam in mining dump truck was analyzed and studied.By employing assembly jigs,controlling the welding sequence and preheating temperature,as well as utilizing FANUC robot contact positioning,multi-layer and multi-pass welding,and arc tracking functions to design a welding path for the frame longitudinal beam.The welding deformation was controlled within 5 mm,solving the long-standing issue of deformation reaching up to 10 mm.This method reduced workers labor intensity,improved welding efficiency,lowered welding rework costs,and ensured production quality.
