Description

Technical Field

[0001] The utility model relates to a welding auxiliary device for an evaporator manifold assembly. Background Art

[0002] The evaporator assembly is one of the common components of an air source heat pump. It has a simple structure, with fins increasing the heat exchange area and high heat transfer efficiency. Among them, the manifold assembly is an important structural form. However, during the welding process of the manifold and the manifold branch pipes, due to the existence of gaps in the assembly, when welding, the vertically upward manifold branch pipes often tilt, and the consistency after welding is poor, which has a great impact on subsequent use and the assembly of the evaporator. For example, the manifold branch pipe cannot be aligned with the evaporator bell mouth, or it needs to be installed by adding processes such as shaping and knocking, which greatly affects the efficiency and quality. Summary of the Utility Model

[0003] In view of the above problems, the utility model provides a welding auxiliary device for an evaporator manifold assembly, which effectively solves the problems pointed out in the background art.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A welding auxiliary device for an evaporator manifold assembly includes a bottom support and a seat. A main pipe placement groove is formed at the top of one side of the bottom support. The lower parts of both ends of the seat are fixed to the side of the bottom support close to the main pipe placement groove. The seat is provided with a plurality of longitudinally arranged branch pipe grooves on the side facing the bottom support, and the branch pipe grooves are located directly above the main pipe placement groove.

[0006] Preferably, the branch pipe grooves on the seat are equidistantly distributed horizontally.

[0007] Preferably, the cross-sections of both the main pipe placement groove and the branch pipe grooves are circular with an arc less than π.

[0008] The circular main pipe placement groove and branch pipe grooves can accurately position the manifold and the branch pipes, ensuring the welding accuracy.

[0009] Preferably, a weld joint is formed on the seat at a position above the bottom support and runs horizontally through the seat.

[0010] The setting of the weld joint facilitates the insertion of the welding torch on this side during welding.

[0011] Preferably, the seat and the bottom support are fixedly connected by bolts.

[0012] The utility model eliminates the defects such as inclination and unevenness existing after welding by means of a simple structure and a flexible and detachable device. A welding space is reserved at the lower part of the seat, which is convenient for welding guns to weld from both sides, reducing the shaping process of workers, greatly improving the production efficiency, reducing the production cost, ensuring reliable quality, making the welding neat and uniform, and facilitating the subsequent assembly and welding with the evaporator.

[0013] The seat and the bottom support of the utility model are fixed by bolts to achieve detachability, and can be repaired and replaced separately when the bottom support or the seat is damaged. Description of the Drawings
