TECHNICAL FIELD
[0001] The utility model relates to the field of part detection, especially a precision hardware part flatness testing device. BACKGROUND
[0002] Flatness refers to the flatness of the measured surface relative to the ideal surface, which is an important indicator of workpiece quality. Flatness detection plays a crucial role in ensuring product performance, extending service life, and reducing failures. At the same time, flatness detection is also one of the important means of enterprise quality control.
[0003] When detecting the flatness of the surface of a part, a dial gauge tool is needed. However, the current detection method is to move the dial gauge horizontally along the surface of the part for a distance and observe the change in the dial gauge pointer. Horizontal movement cannot detect changes in the flatness of other planes on the surface of the part. If the operator detects multiple times by moving horizontally, the detection efficiency is slow, so a precision hardware part flatness testing device is needed. UTILITY MODEL CONTENT
