Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding anti-deformation device for prefabricated buildings. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, welding-related technologies are also constantly improving. Prefabricated buildings are a type of building that uses industrialized production methods to prefabricate some or all of the building components in a factory and then transport them to the construction site for assembly. In prefabricated buildings, welding is an important way to connect various components.

[0003] Patent document with publication number CN221454729U discloses a welding anti-deformation device for prefabricated buildings, including a box body, a welding table is provided inside the box body, and a set of fixing plates are installed at the bottom center of the corresponding two side edges of the welding table.

[0004] While the aforementioned patent documents have solved the problem of lack of stability during welding, the following drawbacks still exist: Although the components of prefabricated buildings can be firmly fixed and deformed during welding, multiple telescopic rods and lifting platforms are required to fix the components, which results in high production costs. Furthermore, when the pressure block or clamping plate is damaged, the fixing effect on the components will deteriorate, making it difficult to weld the components effectively afterward, which is detrimental to the use of the device. Utility Model Content

[0005] The purpose of this invention is to address the following shortcomings in the existing technology: although the components of prefabricated buildings can be firmly fixed and deformed during welding, multiple telescopic rods and lifting platforms are required to fix the components, which results in high production costs. Furthermore, when the pressure block or clamping plate is damaged, the fixing effect on the components deteriorates, making it difficult to weld the components properly afterward, which is detrimental to the use of the device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A welding anti-deformation device for prefabricated buildings includes a welding table and two servo motors mounted on the welding table. The welding table has a rectangular opening, and a bidirectional lead screw and a rotating rod are rotatably connected inside the rectangular opening. Two sliders are threaded onto the bidirectional lead screw, and a mounting plate is fixedly connected to each slider. Two clamping plates are fixedly connected to the mounting plate. Each mounting plate has a groove, and a convex block is connected to the groove by a spring. A pressure plate is connected to the convex block by bolts. Two sliding cylinders are slidably connected to the rotating rod. Each sliding cylinder is connected to the corresponding convex block by a pull rope. Each sliding cylinder is equipped with a rotating component. An installation component is provided on the welding table.

[0007] Preferably, each of the rotating components includes a rotating ring rotatably mounted on the sliding cylinder, an annular groove for connecting the rotating ring is provided on one side of the sliding cylinder, and a concave strip is fixedly connected to one side of the rotating ring, the concave strip and the corresponding slider are fixedly connected.

[0008] Preferably, the rotating rod has a rectangular cross-section, and each sliding cylinder has a rectangular sliding opening for connecting the rotating rod.

[0009] Preferably, the mounting assembly includes a plurality of ear plates fixedly mounted on the welding table, each ear plate having a mounting hole.

[0010] Preferably, each of the clamps is inclined, and a rubber pad is fixedly installed on one side surface of each clamp.

[0011] Preferably, a fixing rod is fixedly connected in each of the grooves, and the convex block and the fixing rod are slidably connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The prefabricated building component to be welded is placed on the welding table. The servo motor drives the bidirectional lead screw to rotate, causing two sliders to move the mounting plate and clamping plate closer to the component. Using the inclined surface of the clamping plate and the rubber pad, the side of the component is initially clamped and centered. After the side of the component is clamped, another servo motor drives the rotating rod to rotate, and the two sliding cylinders rotate simultaneously, which can wind up the pull rope. Under the transmission action of the pull rope, the convex block will move down along the fixed rod. After the two pressure plates move down, the upper surface of the component is pressed. At this time, the component is stably fixed under the three-dimensional constraint of the side clamping plate and the upper pressure plate, avoiding welding deformation. Only two servo motors are needed for driving. The cost of other components such as plates is low. This device can achieve deformation-proof fixing during welding of prefabricated building components at low cost and with high adaptability. It solves the problems of high cost and large impact of vulnerable parts in traditional fixing methods, ensuring the stability of welding operations and component quality, and meeting the welding construction needs of prefabricated buildings.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 A welding anti-deformation device for prefabricated buildings includes a welding table 1 and two servo motors mounted on the welding table 1. The welding table 1 has a rectangular opening 6, and a bidirectional lead screw 7 and a rotating rod 13 are rotatably connected inside the rectangular opening 6. The drive ends of the two servo motors are fixedly connected to the bidirectional lead screw 7 and the rotating rod 13, respectively, and each servo motor drive end is equipped with an electromagnetic brake. Two sliders 15 are threadedly connected to the bidirectional lead screw 7, and a mounting plate 2 is fixedly connected to each slider 15. Two clamping plates 3 are fixedly connected to the mounting plate 2. When the servo motor drives the bidirectional lead screw 7 to rotate, it drives the two sliders 15 to move closer or further away synchronously, so that the mounting plate 2 and the clamping plates 3 move together with the sliders 15, realizing the clamping adaptation of multiple clamping plates 3 to components of different widths.

[0017] refer to Figure 2 Each mounting plate 2 has a groove, and a protruding block 9 is connected to the groove by a spring 11. One end of the spring 11 is fixedly connected to the lower inner wall of the groove, and the other end is fixedly connected to the protruding block 9. The spring 11 can provide a restoring force for the protruding block 9. A pressure plate 4 is bolted to the protruding block 9. The bolt connection method facilitates the replacement and maintenance of the pressure plate 4. Two sliding cylinders 16 are slidably connected to the rotating rod 13. Each sliding cylinder 16 is connected to the corresponding protruding block 9 by a pull rope 12. One end of the pull rope 12 is wrapped around the sliding cylinder 16, and the other end is fixedly connected to the protruding block 9. An opening is opened in the mounting plate 2 for the pull rope 12 to pass through. Each sliding cylinder 16 is equipped with a rotating component. An installation component is provided on the welding table 1.

[0018] refer to Figure 3and Figure 4 Each rotating assembly includes a rotating ring 17 rotatably mounted on a sliding cylinder 16. An annular groove 14 for connecting the rotating ring 17 is provided on one side of the sliding cylinder 16. A concave strip 8 is fixedly connected to one side of the rotating ring 17. The concave strip 8 and the corresponding slider 15 are fixedly connected. The rotating rod 13 has a rectangular cross-section. Each sliding cylinder 16 has a rectangular sliding opening for connecting the rotating rod 13. The rotating rod 13 has a rectangular cross-section that matches the rectangular sliding opening of the sliding cylinder 16, allowing the sliding cylinder 16 to slide along the axial direction of the rotating rod 13 and rotate synchronously with the rotating rod 13. When the sliding cylinder 16 rotates, the rotating ring 17 will rotate relative to the annular groove 14.

[0019] refer to Figure 1 The installation components include multiple ear plates 5 fixedly installed on the welding table 1. Each ear plate 5 has a mounting hole. By passing screws through the mounting holes, the device can be fixed to the construction site ground, welding workstation frame, or other basic carriers, ensuring the overall stability of the device during welding operations and preventing the device from shifting and affecting the component fixing effect. At the same time, when the clamping plate 3 or other components are damaged, the welding table 1 can be replaced.

[0020] refer to Figure 1 Each clamping plate 3 is inclined, and a rubber pad is fixedly installed on one side surface of each clamping plate 3. The inclined design of the clamping plate 3 can automatically center and pre-tighten when it is close to the component. The rubber pad enhances the friction to prevent the component from sliding and avoids damage to the surface of the component during clamping. The distance between the slider 15 is adjusted by the bidirectional screw 7, which drives the clamping plate 3 to move. It can adapt to prefabricated building components with different cross-sectional dimensions, achieve stable clamping on the side, and provide a basic fixation for welding.

[0021] refer to Figure 2 Each groove is fixedly connected with a fixing rod 10, and the convex block 9 and the fixing rod 10 are slidably connected. The fixing rod 10 restricts the convex block 9 to move only along the direction of the groove.

[0022] In this invention, the prefabricated building component to be welded is placed on the welding table 1, and the prefabricated building component is located between multiple clamping plates 3. A servo motor is started to drive the bidirectional lead screw 7 to rotate, causing two sliders 15 to move the mounting plate 2 and clamping plates 3 closer to the component. Using the inclined surface of the clamping plates 3 and the rubber pad, the component's side is initially clamped and centered. When the sliders 15 move, under the transmission action of the concave strip 8 and the rotating ring 17, the sliding cylinder 16 can slide along the rotating rod 13. After the component's side is clamped, another servo motor drives the rotating rod 13 to rotate, causing both sliding cylinders 16 to rotate simultaneously and relative to the corresponding rotating ring 17. The rotation of the sliding cylinders 16 achieves the desired effect. The pull rope 12 is wound up, and under the transmission action of the pull rope 12, the convex block 9 moves down along the fixed rod 10. The spring 11 is compressed and deformed. After the two pressure plates 4 move down, the upper surface of the component can be pressed. At this time, the component is stably fixed under the three-dimensional constraint of the side clamping plate 3 and the upper pressure plate 4, avoiding welding deformation. Only two servo motors are needed for driving. The cost of other components such as plates is low. This device can realize the anti-deformation fixing of prefabricated building components during welding with low cost and high adaptability. It solves the problems of high cost and large impact of vulnerable parts in traditional fixing methods, ensures the stability of welding operations and component quality, and meets the welding construction needs of prefabricated buildings.
