Therefore, in order to complete the welding work between sheet metal assemblies more easily and conveniently, it is usually necessary to use a clamping mechanism to clamp and fix the sheet metal assemblies.

[0003] However, in real life, the traditional clamping mechanism used for welding sheet metal assemblies has poor flexibility when used. Not only is it unable to adjust the weld of the sheet metal assembly to the optimal welding position, resulting in poor welding accuracy of the sheet metal assembly, leading to poor quality of the sheet metal assembly after welding, it is also unable to adjust the sheet metal assembly to a more comfortable position for welding operations, resulting in low safety of the sheet metal assembly during welding operations. At the same time, the traditional clamping mechanism used for welding sheet metal assemblies is often unable to smoothly connect sheet metal assemblies of different specifications together when in use, resulting in a small adaptation range of the clamping mechanism when in use.

A pressing plate 3034 is connected to the bottom of the second hydraulic rod 3033. The pressing plate 3034 at the bottom of the second hydraulic rod 3033 is driven to move up and down by the second hydraulic cylinder 3032 on the two fixing units 303, so that the sheet metal assemblies of different specifications to be welded can be fixed between the pressing plate 3034 and the pad 3035, ensuring that the sheet metal assemblies are more stable during the welding process. This not only avoids sliding and deflection of the sheet metal assemblies during the welding process, improves the stability of the clamping mechanism during use, but also helps to save manpower and further improve the welding efficiency of the sheet metal assemblies.

[0025] A support frame 201 is provided at the bottom of the pulling-in component 2, and the support frame 201 is connected to the counterweight seat 1 by bolts.

Both sliders 204 are provided with first screw holes adapted to the screw 203. By turning on the first motor 202 on the pulling-in component 2, the first motor 202 drives the screw 203 to rotate, and adjusts the distance between the two clamping components 3, so as to facilitate the smooth docking of the sheet metal assemblies on the two fixing units 303, thereby facilitating the welding operation of sheet metal assemblies of different specifications, and further ensuring that the clamping mechanism has a wider range of adaptability when used.

[0026] The support frame 201 is a frame structure, a support block 205 is welded in the middle of the support frame 201, a second screw hole compatible with the lead screw 203 is opened in the middle of the support block 205, the slider 204 is an inverted "convex" structure, and a slideway compatible with the bottom of the slider 204 is opened in the middle of the support frame 201 to ensure the smooth movement of the two clamping components 3, which is beneficial to the smooth contact of the sheet metal assemblies that need to be welded.

A sliding hole compatible with the turning rod 3022 is opened at the top of the lifting plate 3013, and a turning plate 3023 is welded to one end of the turning rod 3022. By turning on the second motor 3021 on the turning unit 302, the second motor 3021 drives the turning plate 3023 at one end of the turning rod 3022 to rotate, adjust the angle of the sheet metal assembly, and ensure that the clamping mechanism is more flexible, which is not only conducive to placing the weld of the sheet metal assembly in the best welding position and improving the welding quality, but also conducive to more conveniently completing the welding operation of the sheet metal assembly, ensuring that the welding operation of the sheet metal assembly is safer, thereby reducing the occurrence of welding accidents, and further conducive to improving the safety of the sheet metal assembly during welding through the clamping mechanism.

[0029] A support plate 3031 is provided on one side of the fixing unit 303, the rotating plate 3023 is connected to the support plate 3031 by bolts, the second hydraulic cylinder 3032 is connected to the top of the support plate 3031 by bolts, a pad 3035 is welded to the bottom of the support plate 3031, the pad 3035 is arranged below the pressure plate 3034, and a rubber pad is provided on one side of the pad 3035 close to the pressure plate 3034, which is beneficial to increase the friction between the sheet metal assembly and the pad 3035, so that the sheet metal assembly after clamping is more stable.

[0030] When in use, first, the second hydraulic cylinder 3032 on the two fixing units 303 drives the pressing plate 3034 at the bottom of the second hydraulic rod 3033 to move up and down, so as to fix the sheet metal assemblies of different specifications to be welded between the pressing plate 3034 and the backing plate 3035, so as to prevent the sheet metal assemblies from sliding and deflecting during the welding process;

[0032] Finally, the first hydraulic cylinder 3011 on the two lifting units 301 drives the lifting plate 3013 on the top of the first hydraulic rod 3012 to move up and down, adjusts the height of the fixing unit 303, and cooperates with the second motor 3021 on the turning unit 302 to drive the rotating plate 3023 at one end of the rotating rod 3022 to rotate, so as to adjust the angle of the sheet metal assembly. This is not only conducive to placing the weld of the sheet metal assembly in the best welding position and improving the welding quality, but also conducive to completing the welding operation of the sheet metal assembly more conveniently, ensuring that the welding operation of the sheet metal assembly is safer, thereby reducing the occurrence of welding accidents.
