[0020] Reference Figure 1-3 , a continuous pulse welding device, comprising a workbench 1 and a welding device 7, a slide groove 2 is provided on the upper end of the workbench 1, and the welding device 7 is installed on the upper end surface of the workbench 1, and the inner wall of the slide groove 2 is rotatably connected with a double-headed threaded rod 15, and two groups of sliders 4 are threadedly connected on the threaded section of the double-headed threaded rod 15, and the two groups of sliders 4 are connected with slide plates 5 through an adjusting mechanism, and multiple groups of sleeves 10 are arranged at equal intervals on the outer wall of the slide plate 5, and the multiple groups of sleeves 10 are respectively connected with limit plates 6 through elastic mechanisms, and the slide plate 5 is slidably connected to the upper end surface of the workbench 1, and the adjusting mechanism comprises a threaded rod 8 threadedly connected to the outer wall of the slide plate 4, and the end of the threaded rod 8 is rotatably connected to the slide plate 5, and the end of the threaded rod 8 is fixedly connected with a turning handle 9, and the two groups of limit plates 6 are driven to slide by the double-headed threaded rod 15, and can be flexibly adjusted when clamping and limiting aluminum alloy plates of different sizes, and the threaded rod 8 is provided at the same time, The position of the two groups of limit plates 6 can be further adjusted to increase the flexibility when using the device.

[0021] Reference Figure 3 The elastic mechanism includes a piston 12 slidably connected in the sleeve 10, a connecting rod 13 is fixedly connected to the outer wall of the piston 12, and one end of the connecting rod 13 away from the piston 12 is fixedly connected to the limit plate 6, a spring 11 is fixedly connected to the bottom of the sleeve 10, and the other end of the spring 11 is fixedly connected to the piston 12. An air hole 14 is opened on the outer wall of the sleeve 10, and the air hole 14 is connected to the inside of the sleeve 10. With the help of the elastic properties of the spring 11 itself and the piston 12, when the aluminum alloy plate is clamped and fixed, the elasticity of the spring 11 can provide a certain clamping force, so that the aluminum alloy plate can remain stable when fixed and will not be damaged by excessive clamping force, and the piston 12 has a certain resistance by contacting with the inner wall of the sleeve 10 when sliding, further improving the stability during clamping.

[0022] Reference Figure 1 and Figure 2 The outer walls of the two sets of sliders 4 are both square, and the outer walls on both sides of the two sets of sliders 4 are in close contact with the inner wall of the slide groove 2.

During the contact process, as the slider 4 slides, the connecting rod 13 is continuously squeezed by the piston 12 and the spring 11. In this process, the elasticity of the spring 11 can provide a certain clamping force, so that the aluminum alloy plate can remain stable when fixed without being damaged by excessive clamping force, and when the piston 12 slides, the air in the sleeve 10 can be discharged through the air hole 14, which has a certain resistance, thereby improving the stability during clamping;
