Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding, and in particular to a steel structure welding device and method. Background Art

[0002] Steel structure is a structure made of steel materials, mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections (such as H-shaped steel, T-shaped steel) and steel plates. There are three main ways to connect steel structure components: weld connection, bolt connection and rivet connection. Among them, weld connection mainly uses the heat generated by the arc to partially melt the welding rod and the weldment, and then cools and condenses into a weld, thereby connecting the weldment into one. Weld connection has the advantages of not weakening the cross-section of the component, saving steel, simple structure and convenient manufacturing;

[0003] When welding steel structure components, the existing steel structure welding device needs to first clamp and limit the components through the provided clamping mechanism, and then use the manipulator to drive the welding gun to weld the matched steel structure components, thereby completing the automatic welding of the steel structure components.

[0004] When the existing steel structure welding device clamps the steel structure components through the clamping mechanism, the matching angles and positions of different steel structure components are also different. When some steel structure components that need to be welded at specific angles are mostly manually held by one of the components, and then matched with another clamped and fixed component, and then welded by an automatic welding mechanism. Since the entire welding process is manually holding the component and matching it with another component, the stability of the matching position angle of the two components cannot be guaranteed, which can easily lead to deviations in the welding angle and position. Moreover, when performing specified angle welding on some heavier components, manual long-term clamping and adjustment is also very troublesome and laborious, which leads to the inability to guarantee the welding quality of steel structure components at different angles.

[0038] When this embodiment is in use, the support frame 10 is slidably installed on the connecting frame 9, and the moving frame 11 is slidably installed on the top of the support frame 10. The support frame 10 is fixed to the output end of the adjusting cylinder 131, so that the user can drive the support frame 10 through the adjusting cylinder 131, thereby changing the supporting height of the support frame 10. The moving frame 11 cooperates with the moving screw 132 through the threaded hole provided on the bottom boss, and the moving screw 132 is fixed to the output shaft of the moving motor 133, so that the user can drive the moving frame 11 through the moving screw 132 and the moving motor 133.
