The bottom of the buffer assembly is fixedly connected with a hot pressing plate 12. The hot pressing plate 12 is used to apply hot pressure to the workpiece to ensure effective heat conduction during the welding process and improve the welding quality. Both sides of the bottom inner wall of the box body 1 are fixedly connected with outer shells 13. The tops of the outer shells 13 are rotatably connected with adjusting assemblies to meet the processing requirements of workpieces with different sizes and shapes. The adjacent sides of the two adjusting assemblies are fixedly connected with cylinders 18. The function of the cylinders 18 is to control the processing components through air pressure to achieve precise positioning and fixing of the workpiece.

[0026] On the adjacent sides of the two adjusting components, C-shaped blocks 17 are fixedly connected, enhancing the overall stability and reliability of the device. The driving end of the cylinder 18 is fixedly connected with a limiting block 19. When the cylinder 18 is started, it drives the limiting block 19 to move, realizing the clamping of the workpiece, improving the controllability and stability of the processing process, and making the processing process more convenient and efficient. On the upper and lower sides of the C-shaped block 17, limiting plates 23 are fixedly connected. On the adjacent sides of the two limiting plates 23, limiting components are arranged to improve the controllability and stability. On the adjacent sides of the two limiting plates 23, clamping blocks 20 are slidably connected, which can effectively connect with the limiting plates and the workpiece, providing a stable clamping and fixing function. On the adjacent sides of the two clamping blocks 20, grooves 21 are arranged. Inside the clamping block 20, two second springs 27 are arranged, providing an adaptive clamping force for the workpiece to ensure that the workpiece will not deform or shift during the processing process. Inside the clamping block 20, a limiting plate 26 is slidably connected. On the outer side wall of the limiting plate 26, a clamping plate 25 is fixedly connected. The limiting plate 26 provides support for the clamping plate 25, improving the stability.

[0027] Refer to Figure 1 , Figure 2 , the buffer assembly includes a fixing plate 4, which plays the role of fixing and stabilizing other components, ensuring the structural stability and reliability of the device. At the four corners of the bottom of the fixing plate 4, telescopic rods 5 are fixedly connected. The design of the telescopic rods 5 is to provide an adjustable support height to adapt to the processing requirements of different workpieces and the operating environment of the device. On both sides of the bottom of the fixing plate 4, connecting rods 6 are rotatably connected. At the bottom of the connecting rod 6, a moving block 7 is rotatably connected. The design of the moving block 7 enables it to move left and right under the guidance of the connecting rod 6 to apply a buffer force to the workpiece, protecting the workpiece from excessive pressure and vibration. At the bottom of the multiple telescopic rods 5, a support plate 11 is fixedly connected. The function of the support plate 11 is to bear the pressure transmission and stable support of the telescopic rods 5, ensuring the stability and reliability of the telescopic rods 5 during the working process. On the top of the support plate 11, a moving groove 10 is opened. The design of the moving groove 10 enables the moving block 7 to move freely therein, thereby adjusting the buffer effect of the workpiece. Inside the inner wall of the moving groove 10, a fixing rod 8 is fixedly connected. The function of the fixing rod 8 is to serve as a guiding track for the moving block 7, ensuring the stable and controllable movement track of the moving block 7. Outside the fixing rod 8, a first spring 9 is sleeved. The function of the first spring 9 is to provide a buffer support force for the moving block 7, enabling the moving block 7 to be stressed smoothly and evenly during the translational movement, and avoiding the deformation or damage of the workpiece caused by the suddenly applied pressure. The through holes of the two moving blocks 7 are respectively slidably connected to the two outer sides of the fixing rod 8, enabling the moving block 7 to move smoothly left and right under the guidance of the fixing rod 8, ensuring that the buffer effect on the workpiece can reach the expected effect and maintaining the stability and reliability of the movement.

[0028] Refer to Figure 2, each adjusting component includes a rotating handle 14, which is designed to facilitate the operator's adjustment. By rotating the handle, fine adjustment of the height or position of the entire device can be achieved to meet the requirements of different workpiece processing or operation. The bottom of the rotating handle 14 is fixedly connected to a threaded rod 15. The outer part of the threaded rod 15 is threadedly connected to a sliding block 16. The function of the sliding block 16 is to carry the movement of the threaded rod 15 and convert it into the adjustment of the device height, while ensuring the stability and smoothness during the adjustment process. The bottom of the rotating handle 14 is rotatably connected to the top of the housing 13. The housing 13, as the external protection structure of the adjusting component, can not only fix the rotating handle 14 but also provide additional support and stability to ensure safety during the adjustment process. The outer side wall of the sliding block 16 is fixedly connected to the inner side wall of the cylinder 18. The sliding block 16 provides support for the cylinder 18 to improve the stability of the cylinder 18 during use. The outer side wall of the sliding block 16 is fixedly connected to the inner side wall of the C-shaped block 17. The sliding block 16 provides support for the C-shaped block 17 to improve the stability when clamping the workpiece.

[0029] Refer to Figure 4 , Figure 5 , each limiting component includes two dovetail blocks 22 and two dovetail grooves 24. The adjacent sides of the two dovetail blocks 22 are respectively fixedly connected to the opposite sides of the two clamping blocks 20. The two dovetail grooves 24 are respectively opened on the adjacent sides of the two limiting plates 23. The setting of the dovetail grooves 24 provides a connection point with the limiting plates 23 for the limiting component and also provides a fixed position to ensure the stability of the device during operation. The outer part of the dovetail block 22 is slidably connected to the inner wall of the dovetail groove 24. This design allows the dovetail block 22 to slide within the dovetail groove 24, thereby realizing the limitation of the position or movement of the device while maintaining the tight connection between the components.

[0030] Refer to Figure 2 、 Figure 3 and Figure 4 , the moving block 7 is slidably connected to the inner wall of the moving groove 10, enabling the moving block 7 to freely move left and right within the moving groove 10, ensuring that the buffering effect on the workpiece can reach the expected effect and maintaining the stability and reliability of the movement. The two ends of the first spring 9 are respectively fixedly connected to the adjacent sides of the two moving blocks 7. The first spring 9 can provide a restoring force to the moving block 7 to ensure that the moving block 7 can maintain balance and stability during the movement. One end of the second spring 27 is fixedly connected to the top inner wall of the clamping block 20, and the other end of the second spring 27 is fixedly connected to the bottom of the limiting plate 26. The second spring 27 provides an adaptive clamping force to the workpiece to ensure that the workpiece will not deform or shift during the processing.

[0031] The outside of the clamping plate 25 is slidably connected to the inner side wall of the clamping block 20. The sliding connection design of the clamping plate 25 enables it to move smoothly up and down inside the clamping block 20, thus realizing the clamping and fixing functions of the workpiece, ensuring the stability and safety of the workpiece during the processing. The outside of the limit block 19 is slidably connected to the inner walls of the two grooves 21 respectively, and the outside of the sliding block 16 is slidably connected to the inner wall of the housing 13, enabling the sliding block 16 to move smoothly up and down inside the housing 13, thus realizing the height adjustment function of the device, while maintaining the stability and reliability of the device structure. The bottom of the threaded rod 15 is rotatably connected to the bottom inner wall of the housing 13. Through its connection with the housing 13, the threaded rod 15 can perform a rotational movement inside the housing 13, thereby adjusting the position of the sliding block 16 to realize the height adjustment and positioning of the component, ensuring the accuracy and stability of the processing process.

[0032] Working principle: When the equipment is needed, place the workpiece to be processed on the loading platform 2 and place the edge of the workpiece on the clamping plate 25. Then start the cylinder 18. Under the force applied by the cylinder 18, push the limit block 19 outwards. Under the action of the limit block 19, the two clamping blocks 20 will move outwards together. At this time, through the restriction of the limiting block 23, the two clamping blocks 20 will slide along the inner wall of the limiting plate 23, making the two clamping blocks 20 approach each other, thereby clamping the workpiece to ensure that the workpiece remains in the correct position during welding, reducing the deformation of the workpiece caused by the position deviation of the workpiece during the welding process, and thus improving the welding quality and production efficiency. Then start the hydraulic cylinder 3. Apply a downward force through the hydraulic cylinder 3 to push the fixed plate 4 downwards. When the fixed plate 4 moves downwards, through the connection between the fixed plate 4 and the support plate 11 by the telescopic rod 5, the fixed plate 4 will drive the support plate 11 downwards, and the support plate 11 will drive the hot pressing plate 12 downwards, making the hot pressing plate 12 close to the loading platform 2. When it contacts the workpiece, the two connecting rods 6 will drive the moving blocks 7 to move respectively, thereby compressing the first spring 9. By the elastic potential energy exerted by the spring, a buffering effect is achieved, absorbing the vibration and impact generated during the processing, and reducing the damage to the workpiece and the processing equipment. This helps to extend the service life of the tools and equipment and improve the processing accuracy.

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