Vehicle air-conditioner pipe profiling assembly, brazing device and working method of brazing device

Abstract

The invention belongs to the field of machinery manufacturing and particularly relates to a vehicle air-conditioner pipe profiling assembly, a brazing device and a working method of the brazing device. In order to solve the problem that brazing of air-conditioner copper pipes with different specification and angle requirements is hardly achieved at the same time, the vehicle air-conditioner pipe profiling assembly provided by the invention comprises two clamping parts between which the interval can be adjusted and which are used for clamping air-conditioner pipes with the different diameter specifications, and two equivalent profiling molds, wherein the interval between the two equivalent profiling molds and the interval between the clamping parts can be adjusted synchronously, the anglesbetween the two equivalent profiling molds and the clamping parts are equal and can be adjusted synchronously, and thus the air-conditioner pipes with the different welding angles can be supported.

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.
