[0002] The Rockwell hardness tester has a wide range of hardness measurement, and the existing metal materials are generally measured using the Rockwell hardness tester. However, the existing Rockwell hardness tester is a desktop structure and can only be used in the laboratory. For example, the invention patent with patent number CN202110804447.4 discloses an integrated calibration device and working method for the Rockwell hardness tester. It adopts an integrated design to reduce the error caused by human operation. The linear accuracy of the displacement is better than 0.2μm, and the force sensor accuracy is 0.3 level and above. It has high stability and long service life, and can replace traditional calibration equipment and methods. In the industrial production process, for some plates with high wear resistance requirements, a large number of measurement points need to be selected for hardness measurement. Test, at the same time, it is necessary to perform a hardness test on the front surface to ensure that the material surface meets the hardness requirements.
