Description

Technical Field

[0001] The utility model relates to the technical field of automobile sheet metal processing, in particular to a sheet metal hole turning fast adjustment fixture. Background Art

[0002] Sheet metal hole flipping, also known as automobile sheet metal hole flipping, is the most commonly used sheet metal processing method in automobile sheet metal. When performing such steps, in order to increase the stability and safety of the operation, the sheet metal parts are generally fixed by corresponding jigs, so as to avoid the displacement of sheet metal parts and safety hazards during the hole flipping process. However, the existing jigs for sheet metal hole flipping still have some shortcomings. For example, they do not have the function of quick adjustment. When flipping holes in different positions of the sheet metal, the operating table of the jig cannot be rotated and adjusted, and generally manual disassembly and reinstallation are required, which not only affects the work efficiency, but also affects the accuracy of the hole flipping. At the same time, the height of the jig cannot be adjusted, resulting in certain limitations in use. For this reason, we propose a sheet metal hole flipping quick adjustment jig.
