While clamping the welded plate 19, the moving plate 12 moves to drive the pull rod 71 to move through the hinge point. The pull rod 71 moves to drive the protective shell 73 to move through the hinge point, so that the two protective shells 73 approach each other, thereby protecting the welded plate 19 during welding and preventing the welding slag from splashing and causing harm to the staff during welding.

[0018] Working principle: When welding the welding plate 19 is required, first place the welding plate 19 on the welding table 9, and then start the workbench 1 to work by the operator operating the device 2. The work of the workbench 1 can drive the sliding device 4 to work. The work of the sliding device 4 drives the adjustment table 5 to move through the mobile end. The movement of the adjustment table 5 can drive the laser welding machine 18 to move, so that the laser welding machine 18 moves to the corresponding position to weld the welding plate 19. At the same time, the workbench 1 will start the electric slide rail 6 to work. The work of the electric slide rail 6 drives the welding table 9 to move through the mobile end. The movement of the welding table 9 drives the welding plate 19 to move to the corresponding position, making the welding of the welding plate 19 more accurate during welding, and the position and parameters can be quickly adjusted, realizing the efficient welding of cylinder seats of different models or specifications, without frequent debugging of the equipment, improving the stability and consistency of the welding process.

At the same time, the movement of the sliding rod 11 drives the connecting plate 13 to move, the movement of the connecting plate 13 drives the pulley one 16 to move, and the movement of the pulley one 16 contacts the inner wall of the guide plate 17 through the circumferential surface, thereby driving the pulley one 16 to move inward. The inward movement of the pulley one 16 drives the connecting plate 13 to move inward, the inward movement of the connecting plate 13 drives the moving plate 12 to move inward, the inward movement of the moving plate 12 drives the elastic telescopic rod one 14 to move inward, and the elastic telescopic rod one 14 drives the clamping plate one 15 to move inward, so that the clamping plate one 15 clamps the welding plate 19. When the clamping plate one 15 clamps, it will make elastic contact with the welding plate 19 through the elastic telescopic end of the elastic telescopic rod one 14, avoiding damage to the welding plate 19, improving the quality of the welding plate 19, overcoming a large rigid clamping force, reducing the labor intensity, and improving the work efficiency.

[0019] While clamping the welded plate 19, the moving plate 12 moves, driving the pull rod 71 to move through the hinge point. The movement of the pull rod 71 drives the protective shell 73 to move through the hinge point, causing the two protective shells 73 to approach each other. Thus, during welding, the welded plate 19 is protected, and it also prevents the welding slag from splashing and causing harm to the staff during welding. When welding is completed, the pull rod 71 is reset by the reset of the moving plate 12, and the reset of the pull rod 71 will open the protective shell 73, avoiding the influence of overheating and damage on its performance and service life. Thus, the stability and reliability of the laser welding device are ensured, the maintenance cost of the equipment is reduced, and the service life of the equipment is increased. While clamping the welded plate 19, the moving plate 12 moves to drive the hinge block 74 to move. The movement of the hinge block 74 drives the hinge rod 75 to move. The movement of the hinge rod 75 drives the sliding plate 76 to move through the hinge point. The movement of the sliding plate 76 drives the second elastic telescopic rod 77 to move. The movement of the second elastic telescopic rod 77 drives the second clamping plate 78 to move through the elastic telescopic end. Thus, the second clamping plate 78 clamps the welded plate 19 in four directions, avoiding defects such as welding cracks caused by stress concentration and reducing welding defects caused by the instability of the welded parts. Thus, the welding efficiency and production efficiency are improved.

When it leaves the convex block 88, the knocking rod 86 will be reset by the spring to knock on the protective shell 73, knocking off the remaining welding slag, improving the cleaning effect of the scraping rod 84 on the protective shell 73, making it more convenient for the staff to clean the protective shell 73, reducing the labor cost, and improving the stability of the equipment; the circumferential surface of the bidirectional threaded rod 81 is rotatably connected to the inner wall of the protective shell 73.

At the same time, the bidirectional threaded rod 81 will drive the rotation of the second pulley 82. The rotation of the second pulley 82 contacts the arc surface of the arc plate 83 through the circumferential surface, thereby driving the second pulley 82 to rotate on its own axis. The rotation of the second pulley 82 on its own axis drives the bidirectional threaded rod 81 to rotate on its own axis. The rotation of the bidirectional threaded rod 81 on its own axis is threadedly connected to the inner wall of the scraping rod 84 through the circumferential surface, thereby driving the scraping rod 84 to move and clean the inner wall of the protective shell 73, avoiding the residue of welding slag on the inner wall of the protective shell 73, improving the service life of the welding equipment, reducing the cost of manual cleaning, making the safety of the staff higher during welding, ensuring the stability of the equipment. While cleaning the protective shell 73, the movement of the scraping rod 84 drives the movement of the L-shaped rod 85. The movement of the L-shaped rod 85 drives the movement of the knocking rod 86. When the knocking rod 86 moves, it contacts the bottom of the convex block 88 through the top, thereby driving the knocking rod 86 to move. When leaving the convex block 88, the knocking rod 86 will be reset by the spring to knock the protective shell 73, knocking off the remaining welding slag, improving the cleaning effect of the scraping rod 84 on the protective shell 73, making it more convenient for the staff to clean the protective shell 73, reducing the labor cost, and improving the stability of the equipment.
