Problems solved by technology

Currently on the market, there is no scale scale or a device for distance measurement on the sliding plate test bench of the Blowy three-purpose microhardness tester. When using the Blowy three-purpose microhardness tester for Vickers hardness test, First observe the area to be tested under the measuring microscope, and then manually slide the stage on the slide plate under the indenter for hardness measurement, so the position of the selected area of ​​the sample cannot be accurately positioned, especially for the distribution of the measurement area. Certainly required samples will have a greater impact on the results

Embodiment Construction

[0017] A sample sliding plate test platform device for a Brockwell hardness tester, which includes a horizontally arranged sliding plate 1, a sliding seat 2 horizontally slidably connected to the sliding plate, and an object table arranged above the sliding seat and horizontally slidably connected to the sliding seat 3. The sliding direction between the sliding board and the sliding seat is perpendicular to the sliding direction between the sliding seat and the stage; the upper surface of the sliding board is provided with a scale along the sliding direction of the sliding board and the sliding seat 4 ;

[0018] The scale scale can conveniently record the moving distance of the sliding seat, which is convenient for the test personnel to accurately move the sample on the stage to ensure the accuracy of the measurement results; the sliding direction between the sliding plate and the sliding seat is perpendicular to the sliding seat and the The sliding direction between the stage...

Abstract

The invention belongs to the technical field of microhardness test, and particularly relates to a test sample stage device for a Brinell hardness gauge. The test sample stage device for the Brinell hardness gauge comprises a slide carriage horizontally arranged, a sliding seat in horizontal sliding connection with the slide carriage, and a stage arranged above the sliding seat and in horizontal sliding connection with the sliding seat; a sliding direction between the slide carriage and the sliding seat is perpendicular to a sliding direction between the sliding seat and the stage; and a scaleruler is arranged on the upper surface of the slide carriage along the sliding direction of the slide carriage and the sliding seat. The invention provides the test sample stage device for the Brinellhardness gauge, which is simple to operate and stable in working state, can implement high-accuracy positioning, is high in repeatability of an experiment result and well solves a problem of carryingout microhardness test on special regions or special positions of certain samples.

Description

Technical field: [0001] The invention belongs to the technical field of microhardness testing, and in particular relates to a sample stage device for a Brockwell hardness tester. Background technique: [0002] Hardness is one of the important indicators of material mechanical properties, and hardness test is an important means to judge the quality of metal materials or parts. A microhardness tester is a precision instrument for hardness testing, which can test the hardness value of a small grain in a sample; when performing a metallographic test of a material, a microhardness tester is often used to test the hardness value of a micro-area of ​​the material , in order to make a reasonable assessment and scientific judgment on the microstructure and performance of the material. Currently on the market, there is no scale scale or a device for distance measurement on the sliding plate test bench of the Blowy three-purpose microhardness tester. When using the Blowy three-purpose...
