Description

Auxiliary clamp for welding ship parts Technical Field The utility model relates to an auxiliary clamp, in particular to an auxiliary clamp for welding ship parts, which is applied to the field of ships. Background The ship is a transportation means which can navigate or park in a water area for transportation or operation and has different technical performances, equipment and structural types according to different use requirements, and in the ship production process, welding is a main process for connecting metal parts, and relates to welding among a plurality of key parts and structures, such as different structures of plates, pipelines and the like. The specification of Chinese patent publication No. CN218891374U discloses a metal plate welding fixture, which can facilitate a user to splice and fix plates with different widths, and the rolling beads can facilitate the user to put the plates on the surface of an L-shaped block, so that the friction resistance during placement is reduced, and certain convenience is brought to use. However, in the practical application process, the problems that in the process of clamping the plate parts, as the shapes of part parts are irregular, the part positions of the plate parts can only be clamped when the part parts are clamped and fixed, so that the clamping is unstable, and the plate parts are easy to shake when welding, so that the accuracy of welding alignment is affected.
