Problems solved by technology

During the measurement process, the specific position of the indentation is found by manually moving the reading microscope. Since the movement is not limited in direction, the indentation will move out of the effective field of view of the reading microscope, and it needs to be re-measured, which reduces the measurement efficiency;
[0007] 3) The rotation angle of the reading microscope cannot be guaranteed
During the measurement process, the diameter is measured by rotating the reading microscope, because the rotation angle cannot be guaranteed, resulting in deviations in the measurement results

Abstract

The invention belongs to the technical field of physical and chemical detection, and discloses a Brinell hardness indentation measuring device. A Brinell hardness sample and a reading microscope are fixed in a clamp. The direction and the rotation angle of the reading microscope are adjusted through the clamp. The Brinell hardness value of a metal material can be accurately and quickly measured, and the efficiency of Brinell hardness detection work and the accuracy and reliability of a result are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical testing, and in particular relates to a Brinell hardness indentation measuring device. Background technique [0002] The Brinell hardness testing of metal materials involved in the development of helicopter models is widely used in the development of helicopter models and the finalization of materials. Detection principle: apply a certain size of test force, press a tungsten carbide ball with a certain diameter into the surface of the tested metal, after a specified holding time, remove the test force, measure the diameter of the indentation on the surface of the sample, and check the Brinell hardness Check the table to get the Brinell hardness value of the sample. Therefore, the accuracy of Brinell hardness indentation diameter measurement results directly affects the Brinell hardness value of metal materials. [0003] At present, the Brinell hardness indentation measurement metho...
