High-frequency welding assembly line for air conditioner liquid adding valve

Abstract

The invention provides a high-frequency welding assembly line for an air conditioner liquid adding valve. The high-frequency welding assembly line comprises a rack, a workbench is arranged at the upper portion of the rack, mounting grooves are formed in the two sides of the workbench, bearing seats are fixed to the mounting grooves, a rotating shaft is rotatably connected between the bearing seats, gear discs are fixed to the rotating shaft, are driven by an output shaft of a motor and are located in the mounting grooves, a chain is connected between the two gear discs and is located on the two sides of the workbench, a plurality of insulating plates are fixed to the chain, support seats are fixed to the insulating plates, position-limiting round pipes are arranged on the support seats, the outer diameters of the position-limiting round pipes are matched with the inner diameters of the connectors, the hole diameters of the position-limiting round pipes are matched with the size of an ejector pin of a valve core, a high-frequency heating machine, a plurality of lower guide plates, a plurality of upper guide wheel assemblies and a heating coil assembly are fixed on the workbench, and the upper guide wheel assemblies are located on the two sides of the chain. By means of the high-frequency welding assembly line for the air conditioner liquid adding valve, the welding efficiency and quality of the liquid adding valve can be remarkably improved.

Description

technical field [0001] The invention relates to a welding line for a filling valve, in particular to a high-frequency welding line for an air-conditioning filling valve. Background technique [0002] When the air conditioner is running, the refrigerant (refrigerant) circulates in each pipeline of the refrigeration (or heating) system to cool (or heat). Since there may be cracks or damage in the pipelines of the refrigeration system, especially the welds or joints of the pipelines, the refrigerant may leak from the refrigeration cycle pipeline, and the refrigerant in the refrigeration cycle pipeline will be reduced due to leakage. , will affect the normal operation of the air conditioner. Therefore, once the refrigerant content in the refrigeration system is too small, it is necessary to replenish the refrigerant to the air-conditioning refrigeration system through the liquid adding device. [0003] The liquid filling joint used for air conditioning in the prior art is inst...

Problems solved by technology

[0004] The existing liquid filling valve welds the joints and copper pipes manually, and the output of 3-4 workers is about 10,000 per day, which greatly limits the production efficiency of the filling valve.
