Automobile headlamp hole threading welding device

The utility model belongs to the technical field of headlamp welding equipment, and particularly relates to an automobile headlamp hole threading welding device which comprises a fixing clamp, an advancing mechanism, a first welding mechanism and a second welding mechanism. The advancing mechanism drives the first welding mechanism and the second welding mechanism to move to the position above the fixing clamp, that is, the first welding mechanism and the second welding mechanism adjust the welding position and the welding angle so as to be aligned with the corresponding headlamp hole threading position of a headlamp on the fixing clamp. And the first welding mechanism and the second welding mechanism are used for welding the threading position of the headlamp hole in sequence. A headlamp is fixed through the fixing clamp, the advancing mechanism drives the first welding mechanism and the second welding mechanism to the position above the fixing clamp, meanwhile, the welding position and the welding angle are
