Description

Technical Field

[0001] This utility model relates to the field of steel structure welding technology, specifically a fixing device for steel structure welding. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are widely used in construction, bridges, ships, and industrial plants due to their advantages such as high strength, light weight, fast construction speed, and good seismic performance. In the manufacturing and installation of steel structures, welding is a crucial connection method, and its quality directly affects the stability and safety of the entire structure. During steel structure welding, high temperatures and stresses are generated. If the welded parts are not secured, problems such as welding deformation and dimensional deviations can easily occur, affecting welding quality and structural performance. Therefore, fixing devices play a vital role in steel structure welding. They effectively fix the welded parts, prevent deformation and movement during the welding process, and ensure the accuracy and stability of the weld.

[0003] Chinese Patent Publication No. CN217291077U discloses a fixing device for welding steel structures, including a workbench, a clamping assembly, and a clamping plate assembly. The workbench has a sliding groove on its upper surface. The clamping assembly includes a ball screw fitted into the sliding groove, the ball screw having a left-hand thread and a right-hand thread, and ball nuts fitted onto both the left-hand and right-hand threads. The clamping plate assembly includes a bracket connected to the ball nuts, a rotating shaft rotatably connected to the bracket, and a clamping block fixedly connected to the rotating shaft. One end face of the clamping block is flat, and the other end face has a clamping groove. This invention solves the problem of inconvenient material fixing when welding materials of different shapes.
