[0002] In the process of welding steel plates, ensuring accurate positioning and firm clamping of the steel plates is the key to achieving high-quality welding.

[0003] Traditional steel plate positioning methods often rely on manual operation, which is not only inefficient but also makes it difficult to guarantee the accuracy and consistency of positioning. This is especially true when dealing with large or irregularly shaped steel plates, where the difficulty of positioning and clamping increases further, easily leading to displacement and deformation during welding, thus affecting welding quality and the overall performance of the product. Therefore, a steel plate welding positioning device needs to be developed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides a steel plate welding positioning device, including a base. Clamping blocks are slidably mounted at both ends of the top of the base. A lead screw is rotatably mounted inside the base. The lead screw is divided into two sections with opposite thread directions, and lead screw sliders are threadedly mounted on the outer sides of both sections. The two lead screw sliders are both slidably connected and limited inside the base. The tops of the two lead screw sliders slide through and extend to the outer top of the base, where two clamping blocks are respectively mounted. A clamping assembly is mounted on the two adjacent sides of the two clamping blocks. The clamping assembly includes a fixing block. A fixing block is fixedly mounted on the two adjacent sides of the two clamping blocks.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a steel plate welding positioning device, such as Figures 1-3 As shown, the system includes a base 1, with clamping blocks 3 slidably mounted at both ends of the top of the base 1. A lead screw 11 is rotatably mounted inside the base 1. The lead screw 11 is divided into two sections with opposite thread directions, and lead screw sliders 12 are threadedly mounted on the outer sides of both sections. The two lead screw sliders 12 are both set inside the base 1 for limiting and sliding connection. The two lead screw sliders 12 slide through and extend to the outer side of the top of the base 1, and are respectively mounted with two clamping blocks 3. A clamping assembly 5 is mounted on the two sides of the two clamping blocks 3 that are close to each other. The clamping assembly 5 includes a fixing block 51. The fixing block 51 is fixedly mounted on the two sides of the two clamping blocks 3 that are close to each other. A threaded rod 53 is threaded through the middle of the fixing block 51, and a pressure plate 54 is mounted on the bottom end of the threaded rod 53.

[0024] In use, the core of this device lies in the lead screw 11 with bidirectional threads installed inside the base 1. The lead screw 11 is divided into two sections with opposite thread directions, and each section is threaded with a lead screw slider 12, which drives the two clamping blocks 3 installed at the top to move towards or away from each other. This design not only allows the device to quickly adapt to and clamp steel plates of various sizes, but also greatly improves the accuracy and consistency of positioning, effectively solving the problems of low efficiency and inaccurate positioning in traditional manual positioning methods.

[0025] Furthermore, each of the two clamping blocks 3 is equipped with a clamping component 5. Through the coordinated action of the fixing block 51, the threaded rod 53, and the pressure plate 54, additional stable support is provided for the steel plate, ensuring that the steel plate will not shift or deform during the welding process, thus further guaranteeing the welding quality. In summary, the steel plate welding positioning device of this utility model, with its innovative mechanical structure and efficient clamping and positioning capabilities, significantly improves the efficiency of welding operations and the quality of finished products, making it an indispensable and efficient auxiliary tool in modern steel plate welding operations.

[0026] In this embodiment, two support legs 2 are installed at both ends of the bottom of the base 1. This not only provides a stable support foundation for the entire device, ensuring that the device will not shake or tip over due to external forces during use, but also increases the distance between the device and the ground, making it easier for operators to clean and maintain the device. It also helps with heat dissipation and extends the service life of the device.

[0027] Specifically, the top of the base 1 has a strip-shaped opening 13 communicating with its interior. The tops of the two lead screw sliders 12 slide through the strip-shaped opening 13 and are fixedly connected to the bottom of the clamping blocks 3 respectively. Driven by the lead screw 11, the two clamping blocks 3 can move smoothly along the strip-shaped opening 13, thereby achieving precise clamping of steel plates of different widths. This design not only improves the flexibility and adaptability of clamping but also ensures stability and consistency during the clamping process, providing a strong guarantee for high-quality welding operations.

[0028] Furthermore, one end of the lead screw 11 is driven to rotate by a motor 4, which is located on the outside of the base 1. The output shaft of the motor 4 extends through the base 1 and is fixedly connected to one end of the lead screw 11. The other end of the lead screw 11 is rotatably connected to the inner wall of the base 1 via a bearing. Driving the lead screw 11 with the motor 4 achieves automated control and improves work efficiency. The rotatable connection of the other end of the lead screw 11 to the inner wall of the base 1 via a bearing ensures the stability and smoothness of the lead screw 11 during rotation, reduces friction and wear, and extends the service life of the device. At the same time, this design also makes the device more compact and easier to maintain.

[0029] Furthermore, a through threaded hole 52 is provided in the middle of the fixing block 51, and the bottom thread of the threaded rod 53 passes through the threaded hole 52, realizing the quick installation and disassembly of the clamping assembly 5, which is convenient for operators to maintain and replace. At the same time, the threaded connection also makes the clamping force more stable and reliable, ensuring the firm clamping of the steel plate during the welding process.

[0030] Furthermore, a gasket 541 is fixedly installed at the bottom of the pressure plate 54. This effectively prevents the pressure plate 54 from directly contacting the surface of the steel plate and causing damage or scratches, thus protecting the integrity and aesthetics of the steel plate.

[0031] Furthermore, a handle 55 is fixedly installed at the top of the threaded rod 53, providing operators with a convenient operating point, allowing them to more easily rotate the threaded rod 53 and adjust the clamping force. This design not only improves the convenience and efficiency of operation but also reduces the labor intensity of operators.

[0032] Furthermore, a heat insulation plate is fixedly installed on the top surface of the base 1. The heat insulation plate can effectively isolate the high temperature generated during the welding process, protecting the overall structure and performance of the device from being affected.

[0033] When using the steel plate welding positioning device of this utility model, the device is initially in a non-working state, the motor 4 is not started, the lead screw 11 is stationary, the clamping blocks 3 are located at both ends of the top of the base 1, and the clamping assembly 5 is in an unclamped state.

[0034] The operator places the steel plate to be welded on top of the base 1, ensuring that both ends of the steel plate are positioned between the clamping blocks 3. The operator starts the motor 4, which drives the lead screw 11 to rotate. Since the lead screw 11 has two sections with opposite thread directions, the rotation of the lead screw 11 causes the two lead screw sliders 12 to move closer to each other, thereby moving the two clamping blocks 3 closer together and gradually clamping the steel plate. The operator can observe the clamping situation of the steel plate and adjust the speed of the motor 4 or stop the motor 4 as needed to ensure that the steel plate is clamped but not too tightly, thus avoiding damage to the steel plate.

[0035] After the steel plate is clamped by the clamping block 3, the operator begins to operate the clamping assembly 5. By rotating the handle 55, the threaded rod 53 is driven to rotate in the threaded hole 52 of the fixing block 51, thereby causing the pressure plate 54 to move downward and press the steel plate tightly. The presence of the gasket 541 protects the surface of the steel plate from being crushed.

[0036] After the steel plate is securely clamped and pressed, the operator can begin welding. The presence of the heat insulation plate effectively isolates the high temperatures generated during welding, protecting the overall structure and performance of the device. After welding is completed, the operator first stops welding, then releases the clamping assembly 5, causing the pressure plate 54 to rise away from the steel plate. Next, they start the motor 4 to rotate in the reverse direction, causing the two clamping blocks 3 to move away from each other, releasing the steel plate. Finally, the operator removes the welded steel plate from the device, preparing for the next round of welding.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
