Commonly used coating testing methods include magnetic induction, coating thickness gauges, and X-ray fluorescence analyzers. These methods have advantages such as high accuracy, fast speed, and simple operation.

[0003] However, existing thickness measuring fixtures do not have a fixed testing position for the product coating during use, resulting in varying measurement data, which affects product quality.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN220437334U discloses a coating thickness detection alignment fixture, comprising a base, a first ring and a second ring at the bottom of a positioning disk, a positioning groove on the positioning disk, a coating thickness gauge on the base, a housing fixedly mounted on the base, a rotating mechanism inside the housing, a support platform on the rotating mechanism, an insert ring on the support platform, and a positioning disk inserted into the insert ring.

[0005] The aforementioned device utilizes a rotating mechanism to drive the positioning disk to rotate during use, thereby facilitating the adjustment of the product's position. However, in this device, the rotating mechanism only drives the positioning disk to rotate, resulting in a relatively fixed product thickness measurement, which affects the product's test results. Therefore, in actual use, a situation may arise where the relatively fixed product thickness measurement affects the product's test results. Utility Model Content
