Clamp for welding automobile parts

The invention relates to a clamp for welding, in particular to a clamp for welding automobile parts. According to the clamp for welding the automobile parts, the automobile parts can be clamped and fixed more stably, and therefore the welding precision of the automobile parts is more effectively improved. A clamp for welding automobile parts comprises a base, a supporting seat, a gravity triggering mechanism, a swing clamping mechanism and the like. Two supporting seats are arranged on the top of the base, the gravity triggering mechanism is arranged on the base, and the swing clamping mechanism is arranged on the base and connected with the supporting seats. According to the clamping device, multiple parts of the axle shaft sleeve can be clamped through the swing clamping mechanism, the arc-shaped clamping rod swings downwards to press the multiple parts of the axle shaft sleeve, the position of the axle shaft sleeve is limited, the multiple parts of the axle shaft sleeve can be conveniently clamped and fixe
