Description

Technical Field

[0001] The utility model relates to the field of mechanical engineering, in particular to a cross aluminum plate assembly welding rotary tool. Background Art

[0002] With the rapid development of cities, aluminum alloy body panels are increasingly used in production and manufacturing. Aluminum alloy body panels have the advantages of light weight, corrosion resistance, and good appearance flatness, and are therefore widely welcomed by the manufacturing industry.

[0003] Currently, the material properties of aluminum alloys and the characteristics of plate thickness have caused many difficulties in aluminum alloy welding. Among them, welding deformation and weld defects are the most frequent production anomalies in the welding and manufacturing process of aluminum alloy plates. The resulting poor shape and dimensional accuracy of aluminum alloy plates and insufficient strength and fatigue performance of welds are one of the root causes of aluminum plate welding failure and even scrap. In the existing technology, for cross aluminum plate welding, it is necessary to measure the angle and then position it before welding. Due to the unique welding characteristics of aluminum and aluminum alloys, aluminum alloys are prone to deformation during welding, forming irreparable defects and causing scrap. In addition, measurement and positioning are time-consuming and labor-intensive, and the welding process is inconvenient to flip, resulting in low production efficiency.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop a cross aluminum plate welding rotating tooling. Utility Model Content
