Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a detection device used for repairing sheet metal parts, and belongs to the technical field of sheet metal part detection equipment. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, and forming. Its most notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts.

[0003] During the machining, casting and subsequent transportation of sheet metal parts, sheet metal parts may be crushed or damaged, causing the flatness of the sheet metal parts to change. Therefore, they need to be tested for flatness. When the flatness of the sheet metal parts is unqualified, they need to be reworked and repaired to ensure that the flatness of the sheet metal parts meets the factory requirements when leaving the factory. However, the preliminary inspection and post-repair inspection of sheet metal parts are usually performed manually. That is, the inspectors use a dial indicator for manual operation and judge the flatness of the sheet metal parts to be tested by eye. This inspection method is extremely inefficient and labor-intensive, and may even result in missed inspections and misjudgments.

[0004] Therefore, in order to ensure that the flatness of the sheet metal parts after repair meets the requirements, we have designed a detection equipment for sheet metal parts repair, especially for some small sheet metal parts. Utility Model Content
