Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure welding, in particular to a steel structure welding device. Background Art

[0002] Currently, steel structure welding is typically performed by placing the steel structure on a welding table and firmly securing it with clamps to prevent movement or shaking during the welding process. However, the existing clamping system is poorly adapted to steel structures of varying lengths. When steel structures vary in length, the fixed clamping system cannot accommodate the various length requirements. This results in a difficult situation when welding steel structures of varying sizes, hindering welding progress due to the inability to find suitable fixing points.

[0003] Since the position of the clamping parts cannot be adjusted, when encountering steel structures of different lengths, tedious adjustment operations are required, such as adding pads, etc. This undoubtedly increases the complexity and time cost of the operation, and seriously affects the efficiency of the welding work.

[0004] In order to solve this problem, we proposed a steel structure welding device that can adjust the clamping position. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel structure welding device to solve the problems raised in the above background technology.

[0006] The utility model is realized by the following technical solutions: a steel structure welding device, comprising: a welding table and a welding head, wherein two sets of adjustable clamping mechanisms are provided in the middle of the welding table, and the adjustable clamping mechanisms include a vertical rod, a push bolt and a circular clamping plate;

[0007] A positioning plate is connected below the vertical pole, a central groove is opened in the middle of the welding table, a compression spring is connected below the positioning plate, a pressure plate is connected below the compression spring, a hollow rod is installed in the middle of the pressure plate, a rotating wheel is connected below the hollow rod, and a central rod is provided above the inside of the hollow rod;

[0008] The central groove is divided into an upper groove and a bottom groove, and the bottom groove is located below the upper groove.

[0009] As a preferred embodiment, a concave plate is installed above the vertical pole, and the front and rear sides of the concave plate are respectively connected to a push bolt through threads, and the rear end of the push bolt is connected to a circular clamping plate.

[0010] As a preferred embodiment, a rubber anti-slip pad is provided on the lower surface of the positioning plate, the upper surface of the central groove is a rough structure, and the positioning plate is arranged above the central groove.

[0011] As a preferred embodiment, the rotating wheel is located in the bottom groove, the pressure plate is located below the upper groove, the lower end of the compression spring is connected to the pressure plate, and the upper end thereof is connected to the positioning plate.

[0012] As a preferred embodiment, the lower end of the central rod penetrates into the hollow rod.

[0013] As a preferred embodiment, a fixed vertical plate is installed on the upper rear side of the welding table, a long slide is installed on the front end of the fixed vertical plate, a short slide is connected below the long slide, both the long slide and the short slide are electric slides, an electric push rod is connected below the short slide, and the welding head is installed below the electric push rod.

[0014] As a preferred embodiment, the left and right sides and the lower surface of the central groove are open structures, and a welding slag box is placed in the middle below the welding table.

[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

[0016] 1. By setting up an adjustable clamping mechanism, it is easy to drive the vertical rod to move horizontally above the center groove, so as to facilitate the adjustment of the use position of the concave plate, and then to facilitate the flexible adjustment of the clamping position, so as to adapt to steel structures of various lengths and broaden the scope of application.

[0017] 2. After the steel structure is clamped, the weight of the steel structure compresses the compression spring, causing the positioning plate to contact the upper surface of the center groove. This structure utilizes the weight of the steel structure itself to achieve a self-reinforcement effect. The interaction between the rubber anti-slip pad and the rough surface of the center groove greatly increases friction, effectively preventing the vertical pole from moving, thereby ensuring the stability of the steel structure during welding.
