Workbench with clamp

Technical Field

The utility model relates to an indentation tester technical field especially relates to a workstation with anchor clamps.

Background

Nano Indentation technology (English: Nanoindenation), also known as Depth-sensitive Indentation technology (DSI), is one of the simplest methods for testing mechanical properties of materials. In the traditional hardness test, an indenter with a specific shape is pressed into a sample by a vertical pressure, and the radius or the length of a diagonal line of an indentation left on the surface of the material is obtained according to an indentation picture after unloading, so that the indentation area is calculated. The workpiece to be measured can be a soft or hard material, including metals, alloys, semiconductors, glass, minerals, organic materials and the like.

The nanoindenter can also be used to make a scratch on the surface of a workpiece, which is scratched with an indenter at a certain load on the surface of the workpiece at a specific horizontal movement rate, causing the material on the surface of the workpiece to break, eventually forming a scratch. However, there is no specific clamp for the currently used nanoindentor, and a 502 adhesion method or a screw clamping method is usually adopted to fix the workpiece to be tested on the test table. If the 502 bonding method is adopted, the workpiece may be damaged when the blade is used for separating the workpiece after the experiment is completed, and the residual colloid may affect the surface appearance of the workpiece. The screw clamping method cannot ensure that the surface of the workpiece is uniformly stressed, and the workpiece is clamped too tightly, so that a gap is formed between the bottom of the workpiece and the platform; too loose clamping may cause the workpiece to move slightly during movement of the indenter, which may affect the mechanical analysis results of the material.
