Control cabinet shell assembling and welding clamp

The invention relates to the field of welding auxiliary equipment, in particular to a control cabinet shell assembling and welding clamp which comprises a fixing part used for being locked on a control cabinet shell, the fixing part comprises T-shaped frames which are symmetrically arranged front and back, and an auxiliary part for supporting a supporting leg is jointly arranged between vertical sections of the two T-shaped frames in an up-down sliding mode. The four supporting legs are clamped and fixed through the four pipe clamping assemblies correspondingly, then the pipe clamping assemblies are driven by the movable transverse frame in cooperation with the movable longitudinal frame to uniformly align the four supporting legs to the welding position, so that the alignment speed is increased, the welding efficiency is improved, the phenomenon that the four supporting legs are mutually staggered can be avoided through uniform alignment, and the welding quality is improved. Therefore, the welding effect of
