Single-station automatic argon arc welding device for finned evaporator

Abstract

The invention relates to the field of argon arc welding machines, in particular to a single-station automatic argon arc welding device for a finned evaporator. The device comprises a rotating mechanism, an automatic wire feeding argon arc welding machine, a liquid accumulator positioning mechanism and a control system; the rotating mechanism comprises a base, a motor arranged on the base and a rotating disc installed on the motor, a stand column is installed on the rotating disc, a first air cylinder is arranged on the stand column, and a first fixture is connected with the first air cylinder; the automatic wire feeding argon arc welding machine comprises an automatic wire feeding disc and an argon arc welding machine body; the liquid accumulator positioning mechanism is arranged on the upper portion of the rotating mechanism and composed of a second air cylinder and a second fixture connected with the second air cylinder; the control system comprises a PLC. According to the single-station automatic argon arc welding device for the finned evaporator, continuous welding operation between an evaporator body and a liquid accumulator assembly can be completed at a time; compared with manual operation, the working efficiency is improved by times, a small quantity of welding wires are used, the welding surface is uniform, the welding quality is stable, and the labor intensity of operators is greatly lowered.

Description

technical field [0001] The invention relates to the field of argon arc welding machines, in particular to an automatic argon arc welding device for a single-station fin evaporator. Background technique [0002] The evaporator is the main part of the four major components of refrigeration. The low-temperature condensed "liquid" body passes through the evaporator to exchange heat with the outside air, and the "gas" absorbs heat to achieve the effect of refrigeration; and the liquid receiver is the compressor. It is an important component that plays the role of storage, gas-liquid separation, filtration, noise reduction and refrigerant buffering. It is composed of cylinder body, inlet pipe, outlet pipe and other parts. At present, in the production process of finned evaporators, the pipeline welding between the evaporator body and the liquid receiver assembly is usually done manually. After bending the pipeline, the welder puts the evaporator body on the table, holds the weldin...
