Description

Technical Field

[0001] The utility model relates to the field of welding positioning equipment, in particular to a condensing water tank welding positioning device. Background Art

[0002] In order to meet the increasingly high technical requirements of the rail transit industry for condensate tanks and meet the installation methods of vehicle suspension parts, it is necessary to strictly control the mounting seat, pipeline installation dimensions and flatness requirements during the condensate tank manufacturing process to ensure that it can match the vehicle body installation interface and achieve smooth installation. The condensate tank is an important part of the engine cooling system. It is usually called a radiator or water tank, and its main function is to cool the engine coolant.

[0003] However, the existing technology uses an installation template to determine the installation dimensions before welding. The excessive heat after welding can easily cause welding deformation and fail to ensure the installation dimensions and overall flatness and pipeline coaxiality requirements. This method mainly results in assembly dimensions exceeding tolerance, flatness exceeding tolerance and failing to meet installation requirements, large workload for adjustment and repair, or even failure to adjust, which can easily lead to waste of production costs and resources such as manpower and material resources.

[0004] Therefore, those skilled in the art provide a condensing water tank welding positioning device to solve the problems raised in the above background technology. Utility Model Content
