[0002] The steel structure welding device disclosed in CN218169151U includes a workbench and a feeding unit; a robotic arm is provided at the right end of the upper middle part of the workbench, and a welding head is provided at the upper end of the robotic arm; a sliding component is provided in the middle of the upper side of the workbench along the front-back direction, and a clamping unit is provided on the upper side of the sliding component.

[0003] In fact, it feeds the workpiece to be welded upwards, and then, under the action of the robotic arm, the welding head performs the welding action on the clamped workpiece.

[0004] However, during the welding of the clamped steel structure, a large amount of iron filings will be generated at the welding point. These iron filings remain on the surface of the welding point, affecting the welding process and aesthetics. This solution is not very efficient for steel structure welding. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a steel structure welding device that solves the problem that during the welding of clamped steel structures, a large amount of iron filings generated during welding are produced at the welding point, and these iron filings remain on the surface of the welding point, affecting the welding process and aesthetics.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel structure welding device, including a workbench, a rotating groove is provided in the middle of the top of the workbench, and a disc is provided at both ends inside the rotating groove. The surface of the disc is rotatably connected with a positive and negative threaded rod. A U-shaped frame is provided on both sides of the rotating groove at the top of the workbench. Sliding holes are provided on both sides of the U-shaped frame in an axially symmetrical manner. A hammer assembly for impacting the steel structure to remove welding debris is provided on the surface of the sliding holes.

[0007] In one specific embodiment, the hammer assembly includes a spring disposed on the surface of the sliding hole, one end of the spring is fixedly connected to a fixing post, one end of the fixing post is fixedly connected to a connecting rod inside the spring, one end of the connecting rod is fixedly connected to a connecting post, one end of the connecting post is fixedly connected to a hammer for striking a steel structure, and the connecting post is slidably connected inside the sliding hole.

[0008] In one specific embodiment, a first clamping frame for positioning one side of the steel structure is threadedly connected to one side of the surface of the positive and negative threaded rod, and a second clamping frame for positioning the other side of the steel structure is threadedly connected to the other side of the surface of the positive and negative threaded rod.

[0009] In one specific embodiment, both the first clamping frame and the second clamping frame are provided with bolts for adjustment and fixing on their sides, and a clamping plate is provided through the surface of the bolt.

[0010] In one specific embodiment, a groove is provided on the top of the U-shaped frame, and a welding machine for welding steel structures is slidably connected inside the groove.

[0011] In one specific embodiment, support columns are fixedly connected to the four corners of the bottom of the workbench, and pads are provided at the bottom of the support columns.

[0012] Compared with the prior art, the present invention provides a steel structure welding device, which has the following beneficial effects:

[0013] In the technical solution disclosed in this utility model, by using the hammer assembly, the steel structure is fixed by the first clamping frame and the second clamping frame during the welding of the steel structure, and then welded by the welding machine. As the welding proceeds, the fixing column can be pulled, causing the fixing column to pull the spring. The spring force is used to stretch the steel structure. At this time, the fixing column is released, and the hammer is impacted by the spring rebound, causing the steel structure to vibrate and dislodging the iron filings generated during welding, thereby ensuring the smooth progress of the welding.

[0014] One end of the connecting rod provided by this utility model is fixedly connected to a connecting column, and one end of the connecting column is fixedly connected to a hammer for striking the steel structure. The connecting column is slidably connected inside the sliding hole. Since the hammer is symmetrically arranged on both sides of the U-shaped frame, it can strike both sides of the steel structure respectively, increasing the efficiency of iron filings falling off, avoiding iron filings remaining on the surface of the steel structure, and increasing the aesthetics of the welding.

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] Figures 1-4 In one embodiment of this utility model, a steel structure welding device includes a workbench 1. A rotating groove 2 is provided in the middle of the top of the workbench 1. A disc 3 is provided at both ends inside the rotating groove 2. A positive and negative threaded rod 4 is rotatably connected to the surface of the disc 3. A U-shaped frame 5 is provided on both sides of the top of the workbench 1 located in the rotating groove 2. A sliding hole 6 is provided on both sides of the U-shaped frame 5 in an axially symmetrical manner. A hammer assembly 7 for impacting the steel structure to remove welding debris is provided on the surface of the sliding hole 6.

[0023] The specific problem addressed in this embodiment is to solve the issue of a large amount of welding debris generated at the welding point during the welding of a clamped steel structure. This debris remains on the surface of the weld, affecting the welding process and aesthetics. This invention utilizes the hammer assembly 7. During steel structure welding, the steel structure is fixed by the first clamping frame 8 and the second clamping frame 9, and then welded using the welding machine 12. As welding progresses, the fixing column 72 can be pulled, causing it to pull the spring 71. The spring 71 stretches the steel structure, and when the fixing column 72 is released, the hammer 732 is rebounded by the spring 71 and impacts the surface of the steel structure, causing vibration and dislodging the welding debris, thus ensuring smooth welding.

[0024] The hammer assembly 7 includes a spring 71 disposed on the surface of the sliding hole 6. One end of the spring 71 is fixedly connected to a fixing post 72, and the other end of the fixing post 72 is fixedly connected to a connecting rod 73 inside the spring 71. In this specific embodiment, one end of the connecting rod 73 is fixedly connected to the connecting post 731, and the other end of the connecting post 731 is fixedly connected to a hammer 732 for striking the steel structure. The connecting post 731 is slidably connected inside the sliding hole 6. Since the hammers 732 are symmetrically arranged on both sides of the U-shaped frame 5, they can strike both sides of the steel structure separately, increasing the efficiency of iron filings falling off, preventing iron filings from remaining on the surface of the steel structure, and increasing the aesthetics of the welding.

[0025] In this specific embodiment, a first clamping frame 8 for positioning one side of the steel structure is threadedly connected to one side of the surface of the positive and negative threaded rod 4, and a second clamping frame 9 for positioning the other side of the steel structure is threadedly connected to the other side of the surface of the positive and negative threaded rod 4. Bolts 10 for adjustment and fixing are provided on the sides of both the first clamping frame 8 and the second clamping frame 9. A clamping plate 11 is provided through the surface of the bolt 10. A sliding groove is opened at the top of the U-shaped frame 5. A welding machine 12 for welding the steel structure is slidably connected inside the sliding groove. Support columns are fixedly connected at the four corners of the bottom of the workbench 1, and a shim is provided at the bottom of the support column.

[0026] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
