Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum single plate welding, and particularly relates to a special-shaped aluminum single plate welding device. BACKGROUND

[0002] The aluminum single plate is a new type of building decoration material, which is made of high-quality aluminum alloy plate as a base material through processes such as numerical control bending and spraying, and has the advantages of light weight, strong weather resistance and good decoration effect.

[0003] When processing the special-shaped aluminum single plate with an arc shape, in order to facilitate subsequent fixing or assembling of the aluminum single plate, one or more arc-shaped connecting plates need to be welded on the outer surface of the aluminum single plate to be fixed or assembled through the arc-shaped connecting plates. When placing the arc-shaped connecting plate to be welded on the aluminum single plate, the workpiece is positioned by a fixed support in cooperation with a clamping plate. However, since the aluminum single plate and the arc-shaped connecting plate to be welded both have a certain arc, and the contact surface of the aluminum single plate and the arc-shaped connecting plate is smooth, the arc-shaped connecting plate is prone to sliding and shifting during the process of placing and clamping. Moreover, the traditional clamping plate is mostly of a planar structure, and has insufficient adhesion to the arc surface of the aluminum single plate. When clamping, the aluminum single plate is prone to deformation, which further leads to a decrease in the position accuracy and welding quality of the arc-shaped connecting plate. In addition, when welding by hand, it is difficult to maintain a stable angle and distance on the curved surface, which further reduces the welding quality.

[0004] Therefore, it is necessary to design a welding device suitable for arc-shaped aluminum single plates and capable of ensuring the position accuracy and welding quality of the arc-shaped connecting plate. SUMMARY
