The invention relates to the technical field of automobile
coating testing, in particular to an automobile
coating adhesion performance testing
machine and a testing method.The automobile
coating adhesion performance testing
machine comprises a base, a limiting block used for limiting a sample plate is fixedly installed on the upper end face of the base, an n-shaped frame located above the limiting block is fixedly installed on the upper end face of the base, and a downward pressing mechanism is arranged on the n-shaped frame. A limiting,
cutting and adhering integrated
operation model is adopted to complete cross-grid testing of different intervals of the automobile coating sample plate, an efficient, accurate and standardized testing process is achieved, uniform
pressure control ensures that the
cutting depth and force of grids with different intervals on the surface of the sample plate are consistent, and a base material is prevented from being damaged; the testing efficiency is greatly improved through cross-shaped limiting and synchronous
cutting, it is ensured that the angle of each grid is accurate to be 90 degrees, meanwhile, coatings with different
hardness and thicknesses can be easily coped with only by adjusting the pressure, the operation consistency is remarkably enhanced in the automatic
adhesive tape adhering and tearing process, and the testing quality and efficiency are comprehensively improved.
