This invention provides a leveling device and method for Vickers hardness testing of high-hardness ceramic materials. The device aims to solve the problems of irregular indentations, inaccurate data, and indenter damage caused by insufficient machining precision leading to non-parallelism of the upper and lower surfaces in Vickers hardness testing. The device includes a base plate for fixing to the original sample stage of the hardness tester, a floating plate connected above the base plate via a ball joint assembly, and three leveling knobs arranged in a triangle, screwed into the floating plate with their lower ends resting against positioning holes in the base plate. By adjusting the leveling knobs, the floating plate can be driven to make omnidirectional micro-motion around the center of the ball joint, thereby directly adjusting the pitch and deflection angles of the sample to be tested, which is fixed to the upper surface of the floating plate. This invention has a compact and low-profile structure, does not interfere with the original function of the hardness tester, and ensures strict parallelism between the test surface and the indenter by "directly leveling the upper surface of the sample," significantly improving testing accuracy and reliability.
