Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a multi-angle welding device for steel structural parts. Background Art

[0002] Steel structure is a structure made of steel material and is one of the main types of building structures. Steel structure mainly consists of steel beams, steel trusses and other components made of two long rods and short rods welded between the two long rods. In the existing welding process of prefabricated steel structures, the short rods to be welded are usually manually erected on the long rods, and then the short rods and long rods are welded to each other by a welding gun. In addition, the short rods need to be welded vertically and obliquely on the long rods, so the angle of the short rods needs to be manually adjusted.

[0003] In the prior art, a Chinese patent document with publication number CN117139945A proposes a welding device for prefabricated steel structures, which can realize convenient material collection of short rods and set the short rods vertically and obliquely at intervals on the long rods. There is no need for manual positioning and stabilization of the short rods, which saves time and effort, has high safety, and is convenient for flipping and welding on the upper and lower sides of the long rods. However, in actual operation, there is still a lack of a multi-angle conversion structure, resulting in the need to manually change the welding angle when facing different welded parts during the welding process, which is time-consuming and labor-intensive to operate and has low welding efficiency. Therefore, the present application discloses a multi-angle welding device for steel structures to meet the multi-angle welding needs of steel structures. Utility Model Content

The swinging component includes a guide rail hole and a sliding rod for limiting the inclination degree of the reduction gearbox, and a fixed plate sleeved on the sliding rod, the fixed plate is connected to a suction cup through a first spring, and the fixed plate is also connected to a positioning rod through a second spring, and the positioning rod is sleeved in the sliding rod.
