Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a flatness testing device for automotive stamping parts. Background Technology

[0002] The flatness of automotive stamping parts directly affects the assembly precision and appearance quality of automobiles. If the stamping parts are not flat, it may cause excessively large or small gaps between parts during automobile assembly, affecting the performance and safety of the entire vehicle. Therefore, after the stamping of automotive parts is completed, the flatness of the stamping parts needs to be inspected and processed.

[0003] After stamping, existing automotive stamping parts require workers to use handheld inspection equipment to inspect them and ensure their quality. However, in practice, manual inspection is slow, and since stamping parts are automotive components, they are produced in large quantities. With such a large number of stamping parts, manual inspection is time-consuming, labor-intensive, and prone to errors, which can affect the quality of the stamping parts and result in unsatisfactory performance in actual operation.
