Automatic welding equipment for transformer

The utility model discloses automatic welding equipment for a transformer. The automatic welding equipment comprises a feeding device, a conveying chain device, a soldering tin device and a rotary actuator, wherein the conveying chain device is used for conveying platform deck jigs to each station; the soldering tin device comprises a soldering tin material pressing rack for controlling the connection of an upper actuator and a lower actuator by soldering tin, and a soldering tin furnace for containing molten soldering tin; the rotary actuator is used for controlling a rotating shaft to rotate in forward and backward directions so that points to be welded on the two sides of the transformer are respectively exposed to the soldering tin in the soldering tin furnace. An automatic welding manner is adopted for replacing a traditional manual welding manner, so that the work efficiency can be improved, the defects, such as damage to the health of operators and rack of fusion caused by manual factors, caused by the
