Automatic welding device for transformer

The invention belongs to the field of transformer production, and provides an automatic transformer welding device which comprises a belt conveyor, the two sides of the belt conveyor are each provided with a feeding mechanism, the two feeding mechanisms are symmetrically distributed about the center line of the belt conveyor, and each feeding mechanism comprises a feeding box; the feeding box is installed on one side of the belt conveyor, a feeding opening matched with the main cooling fins in size is formed in the top of the feeding box, and a chain plate conveyor is installed in the feeding box. The transformer shell which is not welded is placed on the belt conveyor, feeding is conducted through the two feeding boxes on the two sides of the belt conveyor, main cooling fins and side cooling fins can be welded to the transformer shell, the transformer shell does not need to be positioned specially through the arrangement of the pushing mechanism, feeding and discharging are more convenient, and the welding e
