机器人连贯焊接在液压支架结构件上的应用

Application of Robot Continuous Welding in Hydraulic Support Structure

针对焊接机器人在液压支架连贯焊接过程中存在的问题,从结构、焊角大小变化、焊缝路径选择、焊接电流大小变化等方面进行试验分析,提出了有针对性的解决方案。通过将肋板倒角改为便于机器人焊接的圆角,避免了后续对主肋焊缝接头进行手工补焊。通过对离线编程参数、路径的不断调试、优化,实现了同等层数、道数相邻焊缝、圆环焊缝路径优化为直线-圆弧-直线、相同坡口类型不同平面等多种情况下的连贯焊接。经过现场试验验证,在保证焊缝外观、质量的情况下,减少了焊接接头和生产成本。

In view of the problems existing in the continuous welding process of the welding robot in the hydraulic support,the test analysis was carried out from the aspects of structure,weld corner size change,weld path selection,welding current size change,etc.,and the relevant solutions were proposed.By changing the chamfer of the rib plate to a fillet that is easy for robot welding,avoided subsequent manual repair welding of the main rib weld joint.Through the continuous debugging and optimization of offline programming parameters and paths,continuous welding under various scenarios such as the optimization of adjacent welds with the same number of layers and the number of lanes,and toroidal weld paths to straight-arc-straight lines,and different planes of the same bevel type was realized.After testing verification in the field,the weld joint and production cost are reduced under the condition of ensuring the appearance and quality of the weld.
