[0002] Coating thickness gauges can non-destructively measure the thickness of non-magnetic coatings on magnetic metal substrates and the thickness of non-conductive coatings on non-magnetic metal substrates. Coating thickness gauges are usually used in industrial production and quality control. Coating thickness gauges can not only measure various types of coatings, but also include paints, platings, anodized layers, etc. The working principle of coating thickness gauges is usually based on the principle of magnetic induction or radiation absorption. When the coating thickness gauge measures the thickness of the coating, a clamping device is used in conjunction to limit the induction probe to the surface of the object being measured, which can ensure stability and accuracy during measurement.
[0003] At present, when the coating thickness gauges on the market detect the object to be measured, the detection probe of the coating thickness gauge is directly pressed to fit the surface of the object to be measured. When the detection probe of the coating thickness gauge is misaligned and separated from the surface of the object to be measured, the accuracy of the measurement result will be affected. Therefore, we propose a clamping device for the coating thickness gauge. Utility Model Content
