Supporting mechanism for longitudinal seam welding

The utility model belongs to the technical field of cantilever type longitudinal seam welding systems, and particularly relates to a supporting mechanism for longitudinal seam welding. The device comprises a base, a lifting device, a moving mechanism and two supporting plates, the two supporting plates are symmetrically arranged at the top of the lifting device, the lower end of the lifting device is fixedly arranged on the base, and a space used for bearing a mandrel is formed between the two supporting plates; and the moving mechanism is mounted at the bottom of the base. According to the utility model, the problem that the free end of the core shaft may droop after the to-be-welded part is additionally arranged can be solved as much as possible, and the problem of the existing tedious hook locking device can be solved as much as possible. 本实用新型属于悬臂式纵缝焊接系统技术领域，具体涉及一种用于纵缝焊接的支撑机构。本实用新型包括底座、升降装置、移动机构和两个支撑板；两个支撑板对称设置于所述升降装置的顶部，所述升降装置的下端固设于所述底座上，且两个支撑板之间形成用于承载芯轴的空间；所述移动机构安装在所述底座底部。通过本实用新型能够尽量解决芯轴自由端在加装待焊件后有可能出现的
