Description

Technical Field

[0001] This application relates to the field of aluminum plate welding, and in particular to a clamping device for aluminum plate welding. Background Technology

[0002] Aluminum sheet is a widely used material made of aluminum. It is lightweight and easy to handle and install. Sometimes, when processing aluminum sheets, it is necessary to weld two aluminum sheets together.

[0003] Currently, there is a Chinese patent with publication number CN220127989U, which relates to the field of welding fixture technology and discloses a solid aluminum plate welding device. The device includes an outer L-shaped frame, a top plate fixedly connected to the top of the outer L-shaped frame, an inner L-shaped plate slidably connected to the inner wall of the outer L-shaped frame, a side plate fixedly mounted on the side of the inner L-shaped plate, and a clamping plate fixedly mounted on the side of the side plate near the top. A butt groove is formed on the side of the outer L-shaped frame, and a slot is formed on the side of the inner L-shaped plate. Through the cooperation of the limiting frame and the top plate, the limiting frame rotates with the assistance of a round rod at the bottom of the top plate, then the inner wall of the side plate is clamped to the side of the solid aluminum plate until the inner wall of the outer L-shaped frame overlaps with the side of the solid aluminum plate. This allows the outer L-shaped frame and the side plate to stably clamp the solid aluminum plate. Compared to traditional devices, this device facilitates stable positioning of the solid aluminum plate, thus ensuring stable welding.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are that when welding two aluminum plates, the aluminum plates are fixed by a clamping device, and during welding, the two aluminum plates need to be moved and brought together manually to weld the contact points. This method increases the workload of the welding workers, and some existing clamping devices are relatively cumbersome in fixing the aluminum plates, which increases the fixing time and further reduces the welding efficiency of the aluminum plates.
