Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1:

[0025] Please refer to the attached Figure 1 -attached Figure 6, A crossbeam welding device, including a bottom plate 1 and a welding device 4. A clamping assembly 2 is provided on the top of the bottom plate 1. The clamping assembly 2 includes a cylinder 211 and a fixing plate 214. The cylinder 211 is fixedly connected with a connecting rod 213 through a limiting plate 212. One end of the connecting rod 213 is fixedly installed with a support plate 202. Both the support plate 202 and the fixing plate 214 are connected with a gear 205 through a fixing block 203. The inner wall of the gear 205 is movably connected with a support rod 206. A connecting block 204 is fixedly installed on the top of the support plate 202. One end of the connecting block 204 is fixedly installed with a clamping plate 207. An expansion rod 210 is fixedly installed inside the clamping plate 207. The expansion rod 210 is connected with a thimble 208 through a spring 209. A first slider 201 is fixedly installed at the bottom of the support plate 202. A workbench 5 is fixedly installed on the top of the bottom plate 1, and the workbench 5 is fixedly connected to the top of the support rod 206. The end of the connecting rod 213 away from the support plate 202 is fixedly connected to the output end of the cylinder 211. The cylinder 211 is fixedly connected to the left side of the limiting plate 212. The limiting plate 212 is fixedly connected to the left side of the bottom plate 1. The end of the support plate 202 away from the connecting rod 213 is fixedly connected to the left side of the fixing block 203. A rack is fixedly installed on one side of the fixing block 203, and the gear 205 is meshed with the rack. The support rod 206 is fixedly connected to the top of the bottom plate 1. The end of the expansion rod 210 away from the clamping plate 207 is fixedly connected to the thimble 208. The inner wall of the spring 209 is sleeved on the circumferential surface of the expansion rod 210. A groove is opened on one side of the clamping plate 207, and the thimble 208 is movably connected to the inner wall of the groove. A chute is opened on the top of the bottom plate 1, and the first slider 201 is slidably connected to the inner wall of the chute.

[0026] Limit blocks are movably connected to the outsides of both groups of fixing blocks 203, which can limit the excessive movement and shaking of the fixing blocks 203, enhance the stability of the entire clamping assembly 2, and also provide precise positioning for the movement of the fixing blocks 203, avoiding welding deviation caused by inaccurate clamping positions. By starting the cylinder 211, the support plate 202 can drive the fixing block 203 and the rack to move left and right, making the gear 205 mesh with the two racks, and making the fixing plate 214 and the connected components move, which can achieve the effect of left and right clamping. Multiple groups of springs 209, expansion rods 210 and thimbles 208 are provided inside the clamping plate 207, which can apply pressure to the crossbeam from multiple aspects, making it more stable during the clamping process. The thimble 208 can flexibly adapt to different and special crossbeams.

[0027] Specifically, the connecting rod 213 is driven by the cylinder 211, and then the support plate 202 is driven to move. During this process, the fixed block 203 and the rack move left and right synchronously, thereby promoting the meshing transmission of the gear 205, causing the fixing plate 214 and the components connected thereto to move left and right accordingly, thus achieving precise position adjustment. At the same time, the telescopic rod 210, the spring 209 and the ejector pin 208 inside the clamping plate 207 cooperate with each other to provide a flexible and stable clamping force, which can well adapt to crossbeam frames of various different specifications. This component effectively ensures that the crossbeam frame is in a stable state during welding, achieves a firm clamping effect, and effectively guarantees the accuracy of welding.

[0028] Embodiment 2:

[0029] Please refer to the attached Figure 1 and the attached Figure 7 -the attached Figure 8 On the basis of Embodiment 1, it is further obtained that an adjusting assembly 3 is provided on the front side of the bottom plate 1. The adjusting assembly 3 includes a bracket 301. A support column 302 is fixedly installed on one side of the bracket 301 close to the workbench 5. A motor 303 is fixedly installed inside the bracket 301. The motor 303 is connected to a second slider 305 through a threaded rod 304. One end of the threaded rod 304 passes through the support column 302 and is fixedly connected to the output end of the motor 303. The second slider 305 is threadedly connected to the circumferential surface of the threaded rod 304. A bearing seat adapted thereto is fixedly installed at one end of the threaded rod 304 away from the motor 303, and the bearing seat is fixedly connected to the inner wall of the support column 302. The second slider 305 is fixedly connected to the welding device 4.

[0030] The bracket 301 is fixedly connected to the front side of the bottom plate 1, providing a stable support for the entire adjusting assembly 3, reducing welding errors caused by vibration. An installation groove is provided at the intersection of the bracket 301 and the support column 302, and the motor 303 is fixedly connected to the inner wall of the installation groove, reducing damage to the motor 303 from the outside and reducing the deviation when connected to the threaded rod 304.

[0031] Specifically, the motor 303 drives the threaded rod 304 to rotate, and then drives the second slider 305 and the welding device 4 to move left and right, enabling extremely precise adjustment of the specific welding position. This design not only improves the welding efficiency but also can meet various complex welding requirements. This component has the ability to continuously weld crossbeam frames at different positions, eliminating the need for manual adjustment of the welding device 4, greatly saving time and effectively improving the production efficiency of the crossbeam frame.

[0032] Working principle of the present utility model: The present utility model is a welding device for a crossbeam frame. First, place the crossbeam frame on the workbench 5. In the clamping assembly 2, start the cylinder 211 to drive the connecting rod 213 to drive the support plate 202 and the connected components to move. By moving the first slider 201 in the chute, the fixed block 203 and the rack are moved, thereby driving the gear 205 to rotate and engage with the rack, causing the fixing plate 214 to move towards the workbench 5. The telescopic rod 210, the spring 209 and the ejector pin 208 inside the clamping plate 207 come into contact with the crossbeam frame, realizing the clamping of the crossbeam frame. In the adjustment assembly 3, drive the threaded rod 304 to rotate through the motor 303, so that the second slider 305 moves along the threaded rod 304. Since the second slider 305 is fixedly connected to the welding device 4, the welding device 4 is moved to a suitable welding position to weld the crossbeam frame.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
