Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding wire feeding device. Background Technology

[0002] In modern industrial manufacturing systems, welding technology, as a core foundational process, deeply permeates high-end manufacturing fields such as automobile manufacturing and aerospace. Particularly in aerospace equipment manufacturing, the welds of critical load-bearing components like aircraft engine turbine blades often exhibit complex, multi-dimensional curved surface structures, accompanied by stringent angle matching requirements. However, traditional welding wire feeding devices typically employ single-angle welding and wire feeding mechanisms. When dealing with such special-angle welds, it is difficult to precisely adjust to the ideal position and angle matching the weld, leading to welding defects such as undercut and lack of fusion during the welding process. This not only reduces the reliability and safety of the welded structure but also affects engine performance and lifespan, and even jeopardizes flight safety. Therefore, it is necessary to improve existing technologies to solve these problems. Utility Model Content

[0026] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

Similarly, the wire feeding mechanism 5 is equipped with a second spherical universal head 50 and is connected to the welding mechanism 3 through a second locking mechanism 4, allowing the wire feeding mechanism 5 to also rotate flexibly in multiple dimensions. Therefore, when facing complex multi-dimensional curved surface welds on key load-bearing components such as aircraft engine turbine blades, the welding mechanism 3 and the wire feeding mechanism 5 can be easily adjusted to the ideal position and angle that matches the weld, improving welding quality, reducing the risk of structural failure due to welding defects, and thus enhancing the safety of the entire welded structure.
