Description

Technical Field

[0001] The present application belongs to the field of mechanical processing technology, and specifically relates to a butt girth welder. Background Art

[0002] Butt girth welder is a special welding equipment used for welding pipes or circular components. Its function is to connect the workpieces at both ends at the butt weld, and in the process, arc welding is used to make the workpieces at both ends form a whole, thereby achieving the effect of sealing and fixing. This welding method is commonly used in many fields such as petrochemicals, electricity, and water treatment. Compared with other welding methods, butt girth welders have the advantages of high efficiency and good weld quality, so they are widely used in modern manufacturing.

[0003] For example, the publication number: CN107570929A discloses a girth welder, which is characterized in that the mounting plate seat of the girth welder is provided with a girth welding rotating mechanism for driving the hollow rotating shaft to rotate; the girth welding head is provided with a girth welding feeding mechanism for adjusting the vertical distance between the welding assembly and the weldment; the girth welding feeding mechanism is provided with a girth welding angle adjustment mechanism for adjusting the girth welding point of the weldment to be vertical; the mounting plate seat is provided with a weldment clamping assembly that automatically aligns the center line. Its advantages are: scientific structure and powerful functions; the multi-axis motion mechanism can realize the girth welding of the surface of circular weldments, square weldments, rectangular weldments or special-shaped weldments, which is not limited by the shape of the weldment, and the special structure can ensure the stability of the welding distance, high welding accuracy and high degree of automation; the weldment installation does not need to manually calibrate the center line; the fixture replacement adopts the card slot clamping, and the replacement is fast; the overall labor intensity is reduced and the work efficiency is improved.

[0004] However, the butt girth welder in the application cannot automatically adjust the height, making it inconvenient to use, causing damage to the operator's shoulders, neck and back, and indirectly resulting in reduced work efficiency of the operator. Utility Model Content
