One-piece terminal application-based hardness detection method

Abstract

The present invention discloses a one-piece terminal application-based hardness detection method, an integrated terminal machine is set, the integrated terminal machine includes a measuring head, a camera, a camera sensor component and a data processor; the terminal machine is turned on, the measuring head is placed on a test sample, a detecting force is began to load; the camera shoots and gets an impress image, and the impress image is passed back to the data processor by the camera sensor component; detecting force preset load is complete, full load phase is began; the full load phase is completed, the measuring head returns, a camera sensor synchronously stop working; data of the passed-back image is processed by the data processor, and the hardness value of the sample is calculated. The method effectively use application an integrated portable device, is convenient for measuring of hardness of metals of different sizes, different volumes or shapes, and data processing and image processing are synchronously achieved, the measurement time is effectively shortened, the measurement cycle is shortened, and the is efficiency improved.

Description

technical field [0001] The invention relates to metal hardness testing technology, in particular to a hardness testing method based on an integrated terminal application. Background technique [0002] hardness It is one of the most commonly used indicators to evaluate the mechanical properties of metal materials. The essence of hardness is the ability of a material to resist the intrusion of another harder material. For the tested material, hardness represents the comprehensive performance of various physical quantities such as elasticity, plasticity, strength, toughness and wear resistance reflected under a certain indenter and test force. due to pass Hardness test It can reflect the performance difference of metal materials under different chemical composition, organizational structure and heat treatment process conditions, so the hardness test is widely used in the inspection of metal properties, supervision of heat treatment process quality and development of new...

Problems solved by technology

[0003] The testing equipment used in the traditional hardness testing method is large in size, not easy to carry, and cannot meet the product testing in different scenarios or special environments. In particular, the design of the measuring equipment itself limits the volume or size of the measured item. Specific metal products within the scope greatly limit its detection requirements, and the traditional detection method is distributed in the acquisition of indentation images, data conversion and later data processing, which requires a long detection time
