Automatic welding robot for metal corrugated pipe

The invention discloses an automatic welding robot for a metal corrugated pipe. The problem is solved that due to the complexity of the weld joint shape of the metal corrugated pipe, it is difficult to automatically weld the metal corrugated pipe. Automatic welding for the metal corrugated pipe is achieved. The automatic welding robot for the metal corrugated pipe is composed of five parts including a main rotation device, a tensioning rotation device, a push rod movement cart, a welding workbench and a control device. During welding operation, power is provided for a welding gun, it is guaranteed that the welding gun always performs welding along a track of a weld joint, and the weld joint is automatically welded. 本发明公开了一种金属波纹管自动焊接机器人，旨在克服由于金属波纹管焊缝形状的复杂性，金属波纹管焊接难以实现自动的难题，实现其自动焊接。所述金属波纹管自动焊接机器人由主回转装置、张紧旋转装置、推杆移动小车和焊接工作台和控制装置五部分组成，在焊接作业时，为焊枪提供动力，确保焊枪始终沿着焊缝的轨迹焊接，实现焊缝的自动焊接。
