Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal door panel processing, in particular to a fixing device for welding sheet metal door panels. Background Art

[0002] Sheet metal door panels are a common type of door panel. Sheet metal door panels are usually made of metal sheets, such as steel sheets, aluminum sheets, etc. During the manufacturing process, the sheets are first processed into the required shapes and sizes through sheet metal processing techniques such as cutting and stamping.

[0003] During the welding process of sheet metal door panels, stiffeners are welded into the door panels. Welding stiffeners on sheet metal door panels is a common sheet metal processing technique, mainly used to improve the strength and stiffness of sheet metal door panels. They can increase the strength of the door panel, enabling it to withstand greater external forces, such as impacts and squeezes. At the same time, the stiffeners can also improve the stiffness of the door panel, reduce deformation during use, and ensure the flatness and dimensional accuracy of the door panel. In addition, the stiffeners can also improve the acoustic performance of the door panel and reduce noise transmission. The welding methods include the following: manual arc welding: This is a traditional welding method suitable for welding various metal materials. The equipment for manual arc welding is simple and the operation is convenient, but the welding quality is greatly affected by the technical level of the operator. Gas shielded welding: including carbon dioxide gas shielded welding and argon arc welding, etc. Gas shielded welding has the advantages of fast welding speed, good weld quality, and small heat affected zone, and is suitable for welding thin plates and medium-thick plates. Resistance welding: Resistance welding is a method of welding using the resistance heat generated when an electric current passes through the welded parts. Resistance welding has the advantages of high welding efficiency, stable weld quality, and no need for filler materials, and is suitable for welding thin plates. During the welding process, a fixing device is used to fix the sheet metal door panel to facilitate the welding operation.

[0004] In daily work, it is found that when the existing fixing device for welding sheet metal door panels is used for fixing, it is necessary for workers to first place the stiffeners to be welded in the sheet metal door panel, and then use the fixing device for fixing. However, when placing by hand, the accuracy is poor, and the stiffeners are prone to be placed offset, resulting in inaccurate positions of the stiffeners after fixing, causing errors during welding, making the layout of the stiffeners unreasonable, affecting the overall appearance of the normal use of the door panel, and in serious cases, rework is required, thus leading to the problem that the existing fixing device for welding sheet metal door panels is not convenient for accurately fixing the welded stiffeners.
