[0023] Specifically, the motor 2 is fixed by the base 1 so that the motor 2 remains stable during operation, thereby driving the threaded rod 4 to rotate. The rotation of the threaded rod 4 can make the threaded sleeve 5 slide in the slide groove 3. The two slide grooves 3 can limit the movement of the threaded sleeve 5 and the slider 7, so that they maintain horizontal linear motion. The moving direction of the slider 7 is limited by the slide rod 6, so that it can cooperate with the threaded rod 4. The threaded sleeve 5 and the slider 7 drive the support rod 8 to move, which can push the support plate 901 to rotate, so that the horizontal angle of the support plate 901 changes, so that the workpiece fixed by the clamping assembly 9 can be displaced, the position and angle of the workpiece can be adjusted, and at the same time, manual intervention can be reduced, production efficiency can be improved, and human operation errors can be reduced, making the welding process more precise, wherein the support rod 8 supports the support plate 901.

[0024] Reference Figure 3The clamping assembly 9 includes a support plate 901, one end of the support plate 901 is rotatably connected to the top of the base 1, a motor 2 902 is fixedly connected to the bottom of the support plate 901, a rotating rod 903 is fixedly connected to the output end of the motor 2 902, both ends of the rotating rod 903 are rotatably connected to connecting rods 904, the other end of the connecting rod 904 is rotatably connected to a moving rod 905, a clamping plate 906 is fixedly connected to the top of the moving rod 905, both sides of the inner part of the support plate 901 are fixedly connected to guide rods 907, a limiting groove is provided on the top of the support plate 901, the clamping plate 906 is slidably connected in the limiting groove, and both ends of the moving rod 905 are respectively slidably connected to the outside of the guide rod 907.

[0025] Specifically, one end of the support plate 901 is rotatably connected to the top of the base 1, so that the horizontal angle of the clamping assembly 9 can be changed, thereby realizing the displacement of the clamped workpiece and facilitating the adjustment of the welding angle. The motor 2 902 is fixed to the bottom through the support plate 901, so that the motor 2 902 remains stable and does not shake during operation, and then the rotating rod 903 is driven to rotate by the motor 2 902. The rotating rod 903 can drive the connecting rod 904 connected at both ends to move, thereby pulling the moving rod 905 to move through the connecting rod 904, and the two ends of the moving rod 905 slide along the guide rod 907, and the guide rod 907 is fixed inside the support plate 901. The guide rod 907 supports and limits the movement of the moving rod 905. The clamping plate 906 can be driven to move relative to each other through the moving rod 905, and then the clamping operation of the workpiece can be realized through the clamping plate 906. Fixing the workpiece can prevent sliding during welding, thereby affecting the accuracy of welding, and at the same time facilitates the displacement operation, thereby improving the flexibility of the device.

[0026] Reference Figure 1 A support frame 10 is fixedly connected to the top of the base 1, a welding assembly 11 is arranged on the top of the support frame 10, an air pump 12 is fixedly connected to the top of the support frame 10, the input and output ends of the air pump 12 are fixedly connected to connecting pipes 13, one end of one connecting pipe 13 is fixedly connected to a smoking hood 14, and one end of the other connecting pipe 13 is fixedly connected to a filter bin 15, a filter plate 16 is installed inside the filter bin 15, and the filter bin 15 is fixedly connected to the outer side of the support frame 10.

[0027] Specifically, the base 1 supports and fixes the support frame 10, and the air pump 12 is fixed on the top of the support frame 10. The air pump 12 can generate airflow, so that the smoke generated during welding enters the connecting pipe 13 through the smoke hood 14, and then enters the filter bin 15. After being filtered by the filter plate 16, it can be discharged into the air to prevent the smoke generated by welding from floating in the air and causing harm to the human body. At the same time, the filter plate 16 is installed inside the filter bin 15 by a snap-on method, which is convenient for disassembly and replacement. The filter bin 15 is fixed by the support frame 10 to ensure the stability of the overall structure.

[0028] Working principle: When using this device, place the workpiece to be welded above the support plate 901, then start the motor 902 to drive the rotating rod 903 to rotate, thereby driving the connecting rods 904 connected at both ends to move, and pull the moving rod 905 to slide along the guide rod 907 through the connecting rod 904, so that the clamping plate 906 connected to the top of the moving rod 905 moves towards each other, thereby achieving the operation of clamping and fixing the workpiece on the support plate 901, avoiding the movement or shaking of the workpiece during welding, which is beneficial to the accuracy of welding. At the same time, it can be suitable for workpieces of different sizes, improving the applicability of the device. Then, the threaded rod 4 is driven to rotate by the operation of the motor 1 2, so that the threaded sleeve 5 connected to the outside slides along the slide groove 3, and the slider 7 slides along the slide rod 6, and then the threaded sleeve 5 and the slider 7 push the support rod 8 to move, so that the support rod 8 pushes one end of the support plate 901 to rise, and changes its horizontal angle, so as to adjust the welding angle of the clamped workpiece, realize the displacement operation, adjust the position and angle of the workpiece, and reduce manual intervention, improve production efficiency, reduce human operation errors, and make the welding process more accurate. When the air pump 12 is started during welding, the airflow generated by the air pump 12 can make the smoke generated during welding enter the connecting pipe 13 through the fume hood 14, and then be sent to the filter bin 15, and discharged through the treatment of the filter plate 16, thereby reducing the harm of welding smoke to human health and reducing pollution to the environment.
