A high-frequency welding assembly line for air-conditioning liquid filling valve

Abstract

A high-frequency welding line for an air-conditioning liquid filling valve includes a frame, a workbench is arranged on the upper part of the frame, installation grooves are opened on both sides of the workbench, a bearing seat is fixed on the installation groove, and the bearing A rotating shaft is rotatably connected between the seats, a gear plate is fixed on the rotating shaft, the gear plate is driven by the output shaft of the motor, the gear plate is located in the installation groove, and a chain is connected between the two gear plates, and the chain Located on both sides of the workbench, a plurality of insulating plates are fixed on the chain, a support is fixed on the insulating plate, and a limiting circular tube is arranged on the support. The outer diameter of the limiting circular tube and the inner diameter of the joint are The diameter of the limiting circular tube is adapted to the size of the thimble of the valve core, and the 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 worktable; The upper guide wheel assemblies are located on both sides of the chain, and the present invention can significantly improve the welding efficiency and quality of the filling valve.

Description

technical field [0001] The invention relates to a welding assembly line for a liquid adding valve, in particular to a high-frequency welding assembly line for a liquid adding valve of an air conditioner. 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 damages in each pipeline of the refrigeration system, especially the welding or joint connection of each pipeline, the refrigerant may leak from the refrigeration cycle pipeline, and the refrigerant in the refrigeration cycle pipeline is 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 supplement the refrigerant to the air conditioning refrigeration system through the liquid adding device. [0003] The prior art liquid filling joi...

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.
