Description
Technical Field
[0001] This utility model relates to the field of automotive parts coating testing technology, specifically to an automotive parts anti-corrosion coating testing device. Background Technology
[0002] Common automotive parts anti-corrosion coating testing devices use portable coating thickness gauges to measure the thickness of automotive parts placed on a component testing and placement structure. The stability and reliability of the automotive parts placed on the component testing and placement structure affect the subsequent anti-corrosion coating thickness measurement. Taking the component testing and placement structure used in the aforementioned automotive parts anti-corrosion coating testing device as an example.
[0003] The component placement structure used in some automotive parts anti-corrosion coating testing devices employs direct negative pressure adsorption for placement and limiting. This makes it inconvenient to adjust the placement according to the smooth surface support area of the automotive parts, resulting in insufficient stability of the component placement and making it difficult to use a portable coating thickness gauge for anti-corrosion coating thickness testing. Therefore, to address these issues, an automotive parts anti-corrosion coating testing device is proposed. Utility Model Content
