Automatic welding device for four-way valve end cap

Abstract

The invention discloses an automatic welding device for a four-way valve end cap. The automatic welding device consists of a supplied material delivery module, a capillary tube reshaping module, a turntable delivery module, a workpiece feeding and discharging module, a welding ring positioning and containing module, an automatic end cap welding module, a cooling and grinding detection module and aworkpiece overturning and reversing module. The modules perform independent actions, and coordination actions are achieved through a programmable controller. The automatic welding device can achieveautomatic welding of 1-2 products, the production takt is that welding of one product needs 5 seconds, the modules perform parallel actions, and the production efficiency is high only through linkageof the supplied material delivery module, the turntable delivery module and the workpiece feeding and discharging module. The automatic welding device for the four-way valve end cap is a full-automatic device, and the working efficiency and the stability of product quality are greatly improved.

Description

technical field [0001] The invention relates to the field of automation equipment in the four-way valve manufacturing industry, and more specifically relates to an automatic welding equipment for four-way valve end caps. Background technique [0002] With the development of social economy, people's demand for heat pump air conditioners is also increasing. The four-way valve is an important part of the heat pump air conditioner, relying on it to realize the conversion of the refrigerant flow. The end cover welding of the four-way valve is a key process in the four-way valve manufacturing industry, because in the four-way valve manufacturing process, the end cover of the valve body and the capillary are brazed after being assembled as a whole, and the end cover is welded well. Bad will directly affect the yield rate of the four-way valve. Traditional manual brazing is not only labor-intensive, but also has low production efficiency, making it difficult to achieve mass produc...

AI Technical Summary

Problems solved by technology

Traditional manual brazing is not only labor-intensive, but also has low production efficiency, making it difficult to achieve mass production of four-way valves

Although at present, separate end cap welding equipment, separate capillary shaping equipment and separate cooling and grinding testing equipment have been put into use in production, but each equipment operates separately, and operators need to manually load materials, turn workpieces, and move workpieces. All will lead to low production efficiency and poor product consistency

At the same time, the labor cost is high, and the enterprise management cost is also high.
