Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] refer to Figure 1 to Figure 6 , a portable indentation test system with in-situ observation and continuous test functions includes a host test system and a computer system. The host test system includes a working platform adjustment module, a press-in test module, an in-situ observation module and an installation and fixing module. The working platform adjustment module includes a working platform and a working platform lifting adjustment assembly. The working platform and the working platform The lifting adjustment component is connected. The in-situ observation module and the press-in test module are coaxially installed on the turntable of the working platform at a fixed angle relative to each other. The turntable is used to drive the turntable to rotate at a fixed angle to switch between the press-in mode and the observation mode. The switching drive assemb...

Abstract

A portable pressure testing system having in situ observation and continuously testing functions comprises a host testing system, which comprises a working platform adjusting module, a pressure testing module, an in situ observation module and a mounting and fixing module, wherein the working platform adjusting module comprises a working platform and a working platform lifting adjustment assembly, the working platform is connected to the working platform lifting adjustment assembly, the in situ observation module and the pressure testing module are coaxially mounted on a swivel plate of the working platform with respect to each other at a fixed angle, the swivel plate is connected to a switching and driving assembly used for driving the swivel plate to rotate for the fixed angle to implement switching between a pressure mode and an observation mode, and the working platform is fixed on the mounting and fixing module used for locating the entire testing system on a surface of an object to be tested. The invention provides a portable pressure testing system having in situ observation and continuously testing functions which can effectively achieve in situ observation, implement continuously testing, and improve testing efficiency and testing accuracy.

Description

technical field [0001] The invention relates to an indentation testing instrument, in particular to an in-situ observation and continuous testing system of a portable indentation instrument. Background technique [0002] Instrumented indentation is a micro-scale (about tens of nanometers to tens of micrometers) mechanical testing system. This type of instrument can automatically and real-time measure and record the load acting on the indenter and the depth of the indented sample during the indentation test cycle. Using load-depth and other information, through inversion analysis, the indentation hardness and indentation of the material can be identified. Mechanical parameters (such as elastic modulus, yield strength, etc.). Among them, the general principles of instrumented nanoindentation test methods have formed relevant international standards (ISO 14577) and national standards (GB / T 22458—2008). In the past two decades, instrumented indentation testing technology has d...
