Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal welding, in particular to a welding tool used for rapid positioning of sheet metal products. Background Art

[0002] Sheet metal is generally made by manually or by die stamping some thin metal plates to produce plastic deformation to form the desired shape and size, and can be further welded or a small amount of mechanical processing to form more complex parts. In the sheet metal processing technology, many sheet metal products are welded by resistance spot welding or arc welding. In the process of sheet metal welding, in order to ensure the welding accuracy, a welding tool is required, which consists of a work platform and a fixture. The fixture is fixed on the work platform, and then the sheet metal is fixed by the fixture; the welding tool has the functions of welding, fixing, pressing, and positioning, and is mainly used for welding various weldable materials, and welding large, medium, and small materials.

[0003] In the existing sheet metal product welding process on the welding fixture, it is often necessary to wait for the previous piece of welding to be completed before the next sheet metal product can be fixed on the welding fixture and then welding can be continued, which has low welding efficiency. At the same time, after the product welding is completed, the welded product needs to be inspected, and the existing inspection method requires the sheet metal product after welding to be placed on a special inspection equipment for inspection. Similarly, the efficiency is low and the space and cost of the inspection equipment need to be prepared. Figure 1 As shown, for welding of drawer-type sheet metal products, it is often necessary to first fix the box body, then fix a side ear, weld, then fix the other side ear, continue welding, and after welding, transfer the sheet metal product to the inspection equipment for inspection, and then fix the box body and a side ear of the next drawer-type sheet metal product, and weld again. The welding efficiency is low, and the conversion of the inspection equipment requires space and inspection personnel, etc., resulting in low efficiency and increased cost of the entire sheet metal product. As disclosed in patent publication number CN215238885U, an adjustable display frame base welding tool can adapt to the welding of chassis with different diameters and support rods with different diameters, but the above-mentioned disadvantages still exist.
