Description

Technical Field

[0001] This utility model relates to the field of welding, and in particular to a steel structure welding device that is easy to position. Background Technology

[0002] Steel structure welding equipment is a specialized device used to assist in positioning, clamping, and welding during the steel structure manufacturing process. It can improve welding accuracy, reduce manual adjustment time, and increase production efficiency. Its core features are rapid positioning, stable clamping, and automation compatibility, making it suitable for fields such as construction, bridges, shipbuilding, and machinery manufacturing.

[0003] Chinese Patent No. CN221640007U discloses a steel structure welding device for easy positioning, including a base. A driving cavity is formed at the center of the top of the base, and a column is movably installed inside the driving cavity. Two mounting blocks are fixedly installed on the tops of the two columns, and positioning mechanisms are rotatably installed on corresponding sides of the two mounting blocks. Through the design of the positioning blocks, movable grooves, positioning frames, threaded rods, and positioning plates, the device can simultaneously position the steel structure and ensure that the steel structure is centered on the positioning block after positioning. Therefore, when two steel structures to be welded are installed, the welding surfaces of the two steel structures can be ensured to be on the same plane, guaranteeing smooth welding operations. Compared to existing methods for positioning steel structures, this device not only positions the steel structure but also automatically aligns the steel structures to be welded, providing convenience for welding operations.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing steel structure welding equipment requires manual adjustment by the operator when welding the workpiece, and it cannot clamp the workpiece in the center position of the welding. The adjustment is prone to deviation, which affects the welding effect of the steel structure. At the same time, it cannot absorb the fumes generated during welding. Utility Model Content

[0005] The purpose of this invention is to address the problems in the prior art where the steel structure cannot be aligned and clamped for real-time adjustment and where welding fumes cannot be absorbed, and to propose a steel structure welding device that is easy to position.

[0006] The technical solution of this utility model: A steel structure welding device that is easy to position, including a welding table, a fixed column disposed on the top of the welding table, and a connecting plate disposed on the top of the fixed column; further comprising:

[0007] The moving positioning mechanism is located on the top of the welding table and is used to center and clamp the workpiece and automatically move the workpiece to the processing position for fixing.

[0008] The welding mechanism, which is mounted on the connecting plate, is used to absorb the fumes generated during the welding process.

[0009] The mounting platform is mounted on the moving positioning mechanism. An electromagnetic plate is installed on the inner side of the mounting platform, and positioning holes are provided on the mounting plate. The positioning holes and the electromagnetic plate are connected. The mounting platform is used to place steel structure workpieces. After the electromagnetic plate is energized, it generates magnetic force to attract the bottom of the steel structure. The positioning holes are used to receive infrared rays, thereby cooperating with the welding mechanism to determine the position of the steel structure.

[0010] Preferably, the mobile positioning mechanism includes a mobile component and an installation component;

[0011] The movable component is located at the bottom of the mounting frame and is used to move the mounting platform to adjust its position.

[0012] The mounting assembly is located on top of the mounting platform and is used to center, clamp, and fix the steel structure workpiece on the mounting platform.

[0013] Preferably, the moving assembly includes a moving table, a slide, a mounting plate, and a threaded rod;

[0014] A movable platform 1 is located inside the mounting frame. A sliding groove 1 is located on the movable platform 1. A mounting plate 1 is located on the side of the movable platform 1. A threaded rod 1 is threaded onto the mounting plate 1. A motor 1 is located at the end of the threaded rod 1 away from the motor 1. A movable platform 2 is located on the movable platform 2. A sliding groove 2 is located on the movable platform 2. A mounting plate 2 is located at the end of the movable platform 2. A threaded rod 2 is threadedly connected to the mounting plate 2. A motor 2 is located at the end of the threaded rod 2. A support frame 2 is located outside the motor 1.

[0015] Preferably, the mounting components include a straight slide rail, a support frame, a motor, a rotating shaft, and a circular gear;

[0016] The straight slide rail is located on the outside of the mounting platform. There are two straight slide rails symmetrically arranged about the mounting platform. Support frame one is located on the side of the straight slide rail, motor three is located on the inside of support frame one, the rotating shaft is located at the output end of motor three, and a spur gear is located at the end of the rotating shaft away from motor three. A rack meshes with the outside of the spur gear, and a clamping plate is located at the end of the rack away from the spur gear. The bottom of the clamping plate is slidably connected to the straight slide rail.

[0017] Preferably, the welding mechanism includes a cylinder, a push rod, a positioning plate, and a welding assembly;

[0018] The cylinder is located at the top of the connecting plate, the push rod is located at the output end of the cylinder, and the positioning plate is located at the bottom of the push rod.

[0019] The welding assembly is mounted on the positioning plate and is used to weld steel structure workpieces and absorb welding fumes.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] By setting up a moving positioning mechanism, motors one and two drive the mounting platform to move laterally and longitudinally. After the movement is completed, the threaded rods one and two provide instant positioning. Motor three drives the two clamping plates to move in opposite directions for centering and clamping. This allows for quick adjustment of the clamping position to accommodate workpieces of different lengths and widths, avoiding welding deviations caused by mismatched fixing devices. It also allows for quick fixing of workpieces of different sizes, reducing downtime and improving production efficiency. At the same time, it enables precise positioning of the rails in the horizontal and vertical directions, ensuring weld alignment.

[0024] By using a welding mechanism, a cylinder drives the welding head to move and perform welding. The exhaust pipe is pointed at the welding position of the welding head, thus accurately absorbing the fumes during the welding process. The fumes are then treated and discharged through a treatment box. This allows for real-time capture of welding fumes, reducing the concentration of toxic substances in the work area, protecting the respiratory health of welders, reducing contact between fumes and welds, preventing pollutant residue, improving the quality of welded joints, and quickly removing fumes. It also maintains a clear field of vision in the work area, reducing safety accidents caused by obstructed vision. Attached Figure Description

The clamping surface of the clamping plate 214 is set as a wavy surface to enhance the clamping effect.

[0036] Example 2

[0037] like Figure 2As shown, this utility model proposes a steel structure welding device that is easy to position. Compared with Embodiment 1, this embodiment details the structure of the welding mechanism.

After adjustment, cylinder 501, welder 504 and treatment box 506 are started. Cylinder 501 drives push rod 502 to move, and push rod 502 drives positioning plate 503 to move up and down, thereby driving welding head 505 to contact steel structure workpiece for welding. Welding generates fumes. Treatment box 506 contains air pump. Air pump absorbs welding fumes into treatment box 506 through air extraction pipe 507. Treatment box 506 treats the fumes and then discharges them.
