Straight seam automatic welding device

Abstract

The invention belongs to the field of welding devices, and particularly discloses a straight seam automatic welding device. The straight seam automatic welding device comprises a machine frame and a welding structure; the machine frame is provided with a workbench; the middle of the workbench is provided with a strip-shaped groove, the strip-shaped groove coincides with the moving direction of a welding gun, and a positioning plate is located in the strip-shaped groove and can slide up and down along the strip-shaped groove; the two sides of the workbench are provided with pushing mechanisms correspondingly; two side parts of the positioning plate are provided with slide grooves, and each slide groove is internally and slidably connected with a slide rod; the positioning plate is providedwith a cavity, and a vertical column is arranged in the cavity; the upper portion of the vertical column is rotationally connected with an electro-conductive first ring and an electro-conductive second electro-conductive; the slide rods are connected with the first ring / the second ring through connection rods; the surfaces, abutting against each other, of the first ring and the second ring are provided with insulating layers, and the insulating layers of the first ring and the second ring are provided with electro-conductive sections; and the workbench is internally provided with a control structure for controlling the positioning plate to move downwards, and the first ring and the second ring are located in a circuit of the control structure. The straight seam automatic welding device canachieve automatic aligning during welding, and manual operation is reduced.

Description

technical field [0001] The invention belongs to the field of welding devices and specifically discloses a straight seam automatic welding device. Background technique [0002] The garbage incinerator is a device for incinerating garbage. The garbage burns in the furnace and becomes waste gas, which enters the secondary combustion chamber, burns completely under the forced combustion of the burner, and then enters the spray dust collector. After dust removal, it is discharged into the atmosphere through the chimney . The volume of garbage incinerators is generally very large, and when making garbage incinerators, many metal plates are welded together. In order to reduce workers' labor and improve welding efficiency, straight seam welding devices are now mostly used to weld large plates. [0003] Straight seam welding device, also called straight seam welding machine, is an automatic welding equipment for straight seam welding of workpieces through automation and mechanizati...

Problems solved by technology

When welding, it is necessary to ensure that the positions to be welded of the two workpieces to be welded coincide with the moving route of the welding torch. This requires people to constantly adjust the positions of the two workpieces to be welded when placing the workpieces to be welded so that the two workpieces to be welded The alignment end of the workpiece coincides with the moving position of the welding torch, which is not only cumbersome to operate, but also easily leads to a deviation between the alignment position of the two workpieces to be welded and the moving position of the welding torch during manual operation, resulting in weak welding and affecting the quality of the waste incinerator
