Description

Assembly and welding tool for air duct of locomotive underframe

technical field

The embodiment of the utility model relates to the field of welding technology, in particular to an assembly welding tool for an air duct of a locomotive underframe.

Background technique

With the continuous development and progress of the social economy, the number of electric locomotives is increasing, and the quality of locomotive manufacturing is also getting higher and higher. As one of the important parts of the welded parts of the chassis, the ventilation channel of the chassis is welded on the cover plate of the chassis to play a transitional role. The cooling air enters from the side wall filter and is cooled by the traction motor fan through the air duct. The air is fed into the traction motors for cooling and finally exhausted into the atmosphere. Since the steel plate of the air channel of the underframe is relatively thin, only 3mm, there are many weld seams, and it is welded on both sides, so the deformation is relatively large during the welding process, and the flatness of the air channel bottom plate does not meet the production requirements, resulting in the air channel in the air channel. There is a large gap in the process of welding with the bottom frame cover, and welding is difficult, which affects the production of the next process.
