[0002] With the continuous development of industrial production and science and technology, aluminum and aluminum alloy are widely used in aerospace, automobile manufacturing, shipbuilding, electronics and electrical appliances due to their excellent properties such as light weight, corrosion resistance and good thermal conductivity. In order to meet the design requirements of various complex shapes and structures of aluminum plates, the connection between aluminum plates is usually achieved by welding. In the existing aluminum plate welding process, workers first fix a piece of aluminum plate to be welded, then align the edge of another aluminum plate with the previous one, and then weld the welding position with a welding gun. However, this operation method has welding errors, especially for curved aluminum plates or long plates, which can easily affect the processing precision of aluminum plate forming and the quality of welds, and also increases the labor intensity of workers.

In the utility model, by the setting of bearing frame, clamping plate, clamping frame and movable frame, people place the aluminum plate with arc structure in the clamping frame, and can support the clamping frame through the supporting rod. Then, the clamping plate is pressed down on the surface of the aluminum plate under the driving action of electric push rod and movable rod, and the clamping work of the aluminum plate is completed. Then, the rotating shaft is driven to rotate by the motor, so that the movable frames on both sides move towards each other until the aluminum plates contact, and the gap between the aluminum plates is convenient for welding operation.
