Abstract

The invention discloses a Rockwell hardness tester in the technical field of hardness testing. The Rockwell hardness tester comprises a detection module, the detection module comprises a displacementsensor and a pressure sensor, an output end of the detection module is electrically connected to an input end of a level switch module, an output end of the level switch module is electrically connected to an input end of an ARM processor, an output end of a wireless communication module is electrically connected to an input end of a remote terminal, and the ARM processor is electrically and bidirectionally connected to a human-machine interaction module and a data processing module and is mainly applied to acquire and process signals of a digital capacitive displacement sensor, and the digital capacitive displacement sensor has a unique structure in which a reflective electrode is arranged in a combing electrode so that an emitter and a receiver are on a moving-scale instrument. Through the language programming of the ARM processor, the functions of data display, function control and data transmission are realized. The Rockwell hardness tester has the advantages of low cost, simple test method and high performances.

Description

technical field [0001] The invention relates to the technical field of hardness testing, in particular to a Rockwell hardness testing machine. Background technique [0002] Rockwell hardness is an index to determine the hardness value by the depth of indentation plastic deformation, with 0.002 mm as a hardness unit. Using different indenters and different test forces in the Rockwell hardness test will produce different combinations, corresponding to scales with different Rockwell hardness. There are three commonly used rulers, and their applications cover almost all commonly used metal materials. Since the 1980s, with the development and progress of the description of science and technology in the form of reform and opening up, various hardness testers and metrological testing technologies have made great progress, providing a powerful foundation for scientific development, product quality improvement and metrological testing. Guarantee, the existing Rockwell hardness test...
