Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a positioning device for welding a D-tube of a four-way valve component. Background Art

[0002] Early air conditioning systems were mostly cooling-only. With increasing demands for improved living comfort and a growing demand for dual-purpose air conditioners, a four-way valve, capable of conveniently switching between cooling and heating modes, was developed and implemented in air conditioning systems. This component controls the flow of refrigerant, alternating the direction of the compressor's exhaust and return lines into the evaporator and condenser, enabling the transition between cooling and heating.

[0003] During the actual production of four-way valves, the existing tooling can only meet the requirements of positioning and welding the three pipes E, S, and C below the 5P outdoor unit four-way valve component. Since the D pipe is welded in an upward direction, during the welding of the four-way valve D pipe exhaust pipe assembly, the connecting pipe (condenser) can only be hung on the existing universal needle nozzle device for nitrogen filling and positioning welding. Since the pipe size and shape on the universal needle nozzle device are relatively fixed, adjusting the tooling and positioning the D pipe requires a lot of time and effort, which is not conducive to ensuring work efficiency. In addition, due to the influence of tooling accuracy, the consistency of D pipe positioning cannot be guaranteed. There are certain errors in the welding process, which affects the subsequent assembly work and is not conducive to ensuring work efficiency and production costs. Utility Model Content
