Balance beam intelligent welding method based on robot welding production line

Abstract

The invention discloses a balance beam intelligent welding method based on a robot welding production line. An MES issues a production line production scheduling instruction; a balance beam is manually hung and conveyed to a feeding and blanking station; manual code scanning confirmation is performed; an RGV automatically conveys the balance beam to an MES specified welding station; a welding robot performs welding seam welding in the balance beam according to offline program; after the welding is completed, the balance beam is conveyed to the feeding and blanking station by the RGV; the balance beam is manually hung and conveyed to a repair welding station for repair welding; a support pipe and an upper wing plate are installed; the balance beam is manually hung and conveyed to the feeding and blanking station again; the manual code scanning confirmation is performed again; the RGV automatically conveys the balance beam to the MES specified welding station; the robot performs weldingseam welding outside the balance beam according to the offline program; after the welding is completed, the RGV conveys the balance beam to the feeding and blanking station; the balance beam is manually hung and conveyed to the repair welding station; sealing plates at two sides of the box body, an electric pipe and an anti-shearing block are installed; the balance beam is conveyed off the line; and the manual inspection is completed. The method has the advantages that the work intensity of workers is reduced; the welding quality of the balance beam and the management level in the production process are improved; and the construction environment is improved.

Description

technical field [0001] The invention relates to steel structure fabrication of balance beams, more specifically, to an intelligent welding method for balance beams based on a robot welding production line. Background technique [0002] The balance beam is an important part of hoisting equipment and is widely used in hoisting engineering. The balance beam is also called the iron pole. It can be used to maintain the balance of the hoisted equipment and avoid damage to the equipment by the sling; shorten the height of the sling and reduce the lifting height of the movable pulley; reduce the horizontal pressure on the equipment during hoisting to avoid damage to the equipment; when lifting multiple machines, use balance The beam can also reasonably distribute or balance the load of each lifting point. [0003] The existing balance beam adopts manual welding process: pre-assembly, manual turning, artificial flux cored wire gas shielded welding welding inner weld, cover plate, a...

Problems solved by technology

Due to the different positions of the balance beam welds, the workpiece needs to be turned over continuously during the welding process. A single workpiece needs to be turned over more than 10 times to complete the welding. In addition, due to the poor shape of the weld seam in manual welding, the post-weld grinding workload is very large, which not only reduces the work efficiency, and greatly increased the labor intensity of workers, the production environment is harsh
