Description

Technical Field

[0001] The utility model relates to a positioning structure, in particular to a positioning structure used for welding aluminum honeycomb panels. Background Art

[0002] Aluminum honeycomb panels need to be welded after hot pressing. There are two existing welding methods. One is manual welding, which is to place the aluminum honeycomb panels to be welded on the operating table and then weld them with a manual handheld welding gun; the other method is to weld them using a welding device. For example, the Chinese patent application number CN201920257600.4 provides a welding device for aluminum honeycomb panel production. This solution uses a suction cup to fix the aluminum honeycomb panels to prevent the aluminum honeycomb panels at the top of the conveyor belt from slipping sideways during movement. The aluminum honeycomb panels are fed into the position of the welding gun body through the conveyor belt for welding, and then The aluminum honeycomb panels are then fixed to the workbench by a welding gun installed on the workbench. In manual welding, the workpiece to be welded is directly placed on the workbench without positioning the honeycomb panels, which causes shaking during welding. In the above welding devices, the aluminum honeycomb panels are fixed by suction cups during welding. The stability of the adsorption fixation is poor, and each suction cup is located on a conveyor belt. When the conveyor belt feeds the aluminum honeycomb panels to the position of the welding gun body, it is more likely to shake and cause side slipping. In addition, when the aluminum honeycomb panels are placed on the suction cups, the position of the aluminum honeycomb panels on the suction cups cannot be accurately adjusted. Therefore, both methods have the problem of poor stability, which affects the welding quality.
