Abstract

The present invention relates to the technical field of machinery, particularly to a hardness tester provided with a CCD image acquisition system. The hardness tester comprises a hardness tester body, wherein the hardness tester body is provided with a pressing head, the pressing head is fixed on a rotation disk, two object lenses having different magnifications and two CCD camera devices are fixed on the rotation disk, the acquisition directions of the two CCD camera devices are respectively towards the two object lenses, the CCD camera devices are connected to a processor system, the processor system is connected to a display screen, and the display screen is installed on the outer wall of the hardness tester body. According to the present invention, the tested pressing mark is directly displayed on the display screen through the CCD camera device and the processor system analyzes the image collected by the CCD camera device to obtain the hardness value, such that the sight of the test personnel is protected compared to the traditional microscope observation type hardness tester.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a hardness tester. Background technique [0002] The Brinell hardness tester usually measures the hardness by measuring the diagonal length of the indentation with a microscope. The stimulation and visual fatigue brought by the light source of the microscope of the Brinell hardness tester will have a certain impact on the vision of the test personnel. Contents of the invention [0003] The object of the present invention is to provide a hardness tester equipped with a CCD image acquisition system to solve the above technical problems. [0004] The technical problem solved by the present invention can adopt following technical scheme to realize: [0005] A hardness tester equipped with a CCD image acquisition system includes a hardness tester body with a hardness measurement function, the body of the hardness tester is provided with an indenter, and it is characterized in th...
