Robot automatic welding method for special-shaped heavy plate

Abstract

The invention discloses a robot automatic welding method for a special-shaped heavy plate, and relates to the technical field of special-shaped heavy plate welding. The robot automatic welding methodfor the special-shaped heavy plate comprises the following steps of material supplying, assembling, feeding and discharging, front side welding, turning over, reverse side welding, checking and repairing, temporary storing and the like. According to the robot automatic welding method for the special-shaped heavy plate, the automatic welding method based on visual technology autonomous planning isutilized, the production and manufacturing process is optimized, the station arrangement and layout are re-planned, different production processes are allocated according to production requirements inall procedures, so that smooth production operation of the lifting lug heavy plate according to the technological process is realized, the production capacity is greatly improved, and a good foundation is laid for subsequent manufacturing.

Description

technical field [0001] The invention relates to the field of special-shaped heavy plate welding technology, and more specifically refers to a robot automatic welding method for special-shaped heavy plate. Background technique [0002] The product structure of the quay crane is complex and the number of types is large. There are many lifting and binding operations in the production and assembly process, resulting in more types of lifting lug heavy plates in the structure of the quay crane, and in order to ensure the mechanical strength of the lifting lug, a large The heavy plates of some lifting lugs are provided with grooves of different depths, which are different from those used in other heavy machinery industries. Although the structure of the heavy plate of the lifting lug has great similarity, the traditional production method is still a small workshop production, completely relying on traditional handmade. The process is as follows: crane lifting, manual assembly, manu...

AI Technical Summary

Problems solved by technology

Although the structure of the heavy plate of the lifting lug has great similarity, the traditional production method is still a small workshop production, completely relying on traditional handmade. The process is as follows: crane lifting, manual assembly, manual welding, driving turning over, manual Grinding after welding, backward production technology, requiring a lot of labor to ensure production progress, high labor costs, poor welding quality, urgent need to use automated equipment to reduce labor and increase efficiency, improve quality; but because the weld type is fillet weld with groove sewing, the traditional robot tracking and teaching technology is inefficient, and the production progress cannot meet the production demand
