Automatic welding device

Abstract

The invention relates to an automatic welding device. The automatic welding device consists of a working table, a feed conveying mechanism, a clamping positioning mechanism, a welding mechanism and a transfer box, wherein the feed conveying mechanism is arranged on the working table, and consists of a feed rail, a lateral propelling cylinder and a base; the clamping mechanism consists of a lower clamping cylinder, an upper flattening cylinder, a flat retreating cylinder, a stopper, a pressing rod and a bracket; and the welding mechanism consists of a lower welding gun cylinder, a proximity switch, a welding stepper motor, a welding gun, a slide rail and a welding manipulator. The automatic welding device has the following beneficial effects: the manipulator is adopted to finish the argon arc welding through the stepper motor along the sliding rail slideway, so that the precision is accurate, and the welding product quality is guaranteed; and the feed conveying mechanism, the clamping positioning mechanism and the welding mechanism of the automatic welding device are synchronously controlled by a PLC, so that the collaborative operation is realized, the labor intensity of staffs is reduced, and products are high in welding efficiency and excellent in quality.

Description

Technical field [0001] The invention relates to the field of welding tooling, in particular to an automatic welding device. Background technique [0002] Argon arc welding is an arc welding method that uses inert gas-argon as shielding gas. The argon gas sprayed from the nozzle creates a thick and dense gas protection layer in the welding area to isolate it from the air. Under the protection of argon laminar flow, the arc is used between the electrode (tungsten electrode or welding wire) and the workpiece The heat generated by the combustion melts the welded area, and fills or does not fill the welding wire, connecting the separated metals into one body, thereby obtaining a strong welded joint. [0003] Existing argon arc welding machines are mostly manual. When operating, you need to hold the argon arc welding torch in one hand and feed the welding wire in the other hand. The welding work must be completed with both hands. The welding quality depends on the skill and responsibili...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing argon arc welding machines are manual. When operating, you need to hold the argon arc welding torch in one hand and feed the welding wire in the other hand. The welding work must be done with both hands. The welding quality depends on the skills and responsibilities of the operator. Therefore, welding products Unstable quality; low labor efficiency, not suitable for welding batches of workpieces

There are also semi-automatic argon arc welding machines, including argon arc torches and wire feeders, which can complete the argon arc welding work with only one hand, which reduces the labor intensity of the operator, but there are still uneven welding quality and welding inefficiency
