[0040] In the following embodiments, if there is no special description of functional components or structures, it means that they are all conventional components or conventional structures adopted in the art to achieve corresponding functions.

[0041] Embodiment 1:

[0042] As Figures 1-5 shown, it is a welding auxiliary device for a roller group, used to fix the roller group 1 in the horizontal direction. The welding auxiliary device for the roller group includes: a bracket 2; a driving roller mechanism arranged on one side of the bracket 2, used for positioning a first positioning sleeve 8-1 at one end of the roller group 1, and a driving unit connected to the end of the roller group 1 positioned at the first positioning sleeve 8-1 and used for rotating the roller group 1; a driven roller mechanism arranged on the other side of the bracket 2, including a second positioning sleeve 8-2 for positioning the other end of the roller group 1, a cylinder assembly 10 connected to the second positioning sleeve 8-2, and a first slide rail assembly 9 slidably connected to the cylinder assembly 10.
