Experimental solid metering and detecting device

Abstract

The invention relates to an experimental solid metering and detecting device which comprises a fixing mechanism and a detecting mechanism, the fixing mechanism is installed on the existing ground, and the detecting mechanism is arranged at the upper rear end of the fixing mechanism. Experimental solid hardness metering and detecting are performed by adopting the design concept of multi-directional multi-point detection, the whole device can realize multi-surface multi-point position hardness detection of the experimental solid so that the accuracy of hardness detection of the experimental solid is greatly improved, meanwhile, the fixing mechanism can be used for clamping the rectangular experimental solid and also can be suitable for clamping the tubular experimental solid , and the experimental solid can be clamped in multiple directions, and thus the stability of the experimental solid in the hardness metering and detecting period is improved.

Description

technical field [0001] The invention relates to the field of solid measurement and detection, in particular to an experimental solid measurement and detection device. Background technique [0002] Metrology is the use of technical and legal means to achieve unit unity and accurate and reliable measurement. In the measurement process, it is considered that the measuring tools and instruments used are standard, and they are used to calibrate and verify the tested measuring tools and equipment, so as to measure and ensure the reliability of the measurement results obtained when using the tested measuring tools and instruments for measurement. It is a process of obtaining a certain result through a series of repeated tests on the corresponding parameters of the measurement object. In physics, a certain process is usually carried out on a tool by a measuring instrument in order to obtain the correct result. [0003] Common measurement testing can be divided into ten categories: ...

AI Technical Summary

Problems solved by technology

[0004] 1. In the case of no external clamping or only one-sided clamping of the solid used in the test, it is easy to shift during the test period, which will affect the accuracy of the hardness test result;

[0005] 2. The detection device has a narrow range of testing the hardness of the solid surface used in the test, and it is commonly used for single-sided hardness testing, so there is a large deviation in the obtained hardness testing data
