Vehicle air-conditioning pipe mold assembly, brazing device and working method thereof

Abstract

The invention belongs to the field of mechanical manufacturing, and in particular relates to a vehicle air-conditioning pipe template assembly, a brazing device and a working method thereof. In order to solve the problem that it is difficult to adapt to the brazing of air-conditioning copper pipes with different specifications and angle requirements at the same time, the invention provides a vehicle air-conditioning pipe profiling assembly, which includes two clamping parts with adjustable spacing to clamp different diameters Standard air-conditioning pipe; two equivalent profiles, the distance between the two equivalent profiles and the distance between the two clamping parts can be adjusted synchronously, and the distance between the two equivalent profiles and the clamping parts The angles are the same and synchronously adjustable to support air-conditioning pipes with different welding angles.

Description

technical field [0001] The invention belongs to the field of mechanical manufacturing, and in particular relates to a vehicle air-conditioning pipe template assembly, a brazing device and a working method thereof. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Copper tubes are an important part of the air-conditioning system in locomotives and vehicles. Due to the production of copper tubes, it is impossible to use a whole copper tube to manufacture the air-conditioning system. It is necessary to weld the copper tubes to meet the design and use requirements. Air-conditioning copper pipes in locomotives often have a bent structure, and the joints at the bends are used for connection, and the joints are spliced ​​and welded with the copper pipes. The welding of air-conditioning copper pipes mainly uses brazing, adding flux to the welding p...

AI Technical Summary

Problems solved by technology

[0004] The inventors found that the current welding workbench for air-conditioning pipes for locomotives has the following problems: 1) There is no auxiliary structure for fixing the air-conditioning pipes, and there is a butt joint between long pipes and short pipe joints (including flat butt joints and sleeved joints) for air-conditioning pipes. , There are different bending angles at the welding place. During the welding process, the positioning, butt jointing and welding heating process of the copper tube are all done manually. In this way, at least 2-3 people are required to cooperate to complete the welding operation, which consumes labor costs and time costs. And it is difficult to guarantee the accuracy consistency of each batch of workpieces

2) It is only suitable for air-conditioning pipes with one diameter specification or one angle requirement. It is difficult to weld and position multi-angle air-conditioning pipe joints, and it is difficult to adapt to the brazing of air-conditioning pipes with different diameter specifications and angle requirements at the same time.
