[0002] In the process of shipbuilding, sheet metal welding is a crucial link, which is directly related to the structural strength, sealing performance and safety of the ship. There are various sheet metal welding devices for shipbuilding, and these devices are designed according to factors such as welding methods, sheet thickness, and automation level.

[0003] With the development of the shipbuilding industry, the requirements for welding technology are also getting higher and higher. Although traditional welding methods such as manual arc welding and gas shielded welding are flexible in operation, they have problems such as low production efficiency and unstable welding quality. In order to meet the manufacturing needs of large ships, modern sheet metal welding devices for shipbuilding are constantly developing towards automation and intelligence.

[0034] In an alternative embodiment of the present invention, as Figure 9 shown, the driving assembly includes: main bracket 33, long belt 34, motor IV 35, transmission shaft 36, bottom plate 37, and plate 38.

[0035] In an alternative embodiment of the present invention, as Figure 4 shown, the clip 6 is made of titanium alloy material and has relatively high strength.

[0036] In an alternative embodiment of the present invention, as Figure 7 shown, a double-sided synchronous welding assembly is also installed on the sub-slider 16, and this assembly is used during repair welding.

[0037] In an alternative embodiment of the present invention, as Figure 6 shown, helium gas is ejected from the cooling nozzle 18. Helium gas is an inert gas and can be used as a cooling medium to enable rapid cooling. Air is ejected from the blowing nozzle 19, which can blow the welding slag at the welding area clean and prepares for the inspection of the welding surface.

[0038] Working principle: When the present invention is in use, it adopts the main and auxiliary welding forms. During the process of welding the plate 38 by the bilateral synchronous welding assembly on the main slider 1, it can detect whether there is a missed weld. If a missed weld or an incomplete weld is detected, timely repair welding can be carried out, greatly improving the welding quality. At the main welding assembly of the present invention, that is, a mobile fixing mechanism is installed on the main slider 1. This mechanism can move synchronously with the main slider 1, and this mechanism will position the vertical part of the plate 38, thereby ensuring the stability of the splicing part of the plate 38 during the welding process.

[0039] When the present invention is in use, first place the plate 38 to be welded on the limit card on the bottom plate 37. Subsequently, the motor Ⅳ35 is started, and the side slider 31 is driven to slide on the total support 33 through the long belt 34 and the transmission shaft 36, so that the welding assembly moves to the welding seam on the plate 38. Subsequently, the cylinder Ⅰ4 is started, driving the cross beam 3 to slide downward, so that the clamping piece 6 clamps the vertical plate on the plate 38, and the clamping piece 6 can tightly clamp the vertical plate on the plate 38 under the action of the spring 7, thereby fixing it. Subsequently, the motor Ⅲ32 is started, driving the lead screw 30 to rotate, so that the main slider 1 slides, driving the bilateral synchronous welding assembly on the main slider 1 to approach the welding place where the vertical plate and the horizontal plate of the plate 38 intersect. Then, adjust the position of the welding head 11 according to the thickness and shape of the plate 38. Specifically, the cylinder Ⅱ9 drives the square sleeve 10 to slide up and down, which can adjust the height of the welding head 11 up and down. The cylinder Ⅲ15 drives the central slider 13 to move up and down, thereby driving the swing arm 8 to rotate through the connecting rod 12, so as to adjust the left and right movement of the welding head 11, so as to find a suitable welding position for the welding head 11. Subsequently, mobile welding can be carried out.

[0040] During the welding process, since the auxiliary slider 16 and the main slider 1 are connected by the threaded rod 27, the auxiliary slider 16 and the main slider 1 move synchronously. A cooling and cleaning mechanism is provided between the auxiliary slider 16 and the main slider 1. After the welding head 11 on the main slider 1 welds the plate 38, the cooling nozzle 18 sprays helium to quickly cool the welding place. Subsequently, the cleaning brush 20 rotates driven by the motor Ⅰ24 to clean the cooled welding slag. Finally, the air blowing nozzle 19 blows out air to disperse the welding slag, so that there is no welding slag at the welding place. Subsequently, the laser sensor 25 at the back detects through the cleaned welding slag to judge whether there is a missed weld or an incomplete weld. If so, the bilateral synchronous welding assembly on the auxiliary slider 16 will repair weld the defective place again to ensure the welding quality.

[0041] When welding different plates 38, it may be necessary to replace different types of welding heads 11, which may lead to different temperatures at the welding points and thus different cooling effects. By adjusting the distance between the main slider 1 and the secondary slider 16, the natural cooling time can be lengthened or shortened, so as to reach the optimal cooling node and improve the time efficiency of welding. Specifically, when the motor II 28 is started, it drives the threaded rod 27 to rotate, causing the secondary slider 16 to slide on the slide rod II 26, thereby increasing or decreasing the distance between the main slider 1 and the motor II 28, achieving an increase or decrease in the natural cooling time and reaching the optimal control effect.

[0042] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
