二,HVS - AXY Vickers hardness automatic measurement and control system
HVS- AXY Vickers Hardness Measurement and Control System is a
computer automatic measurement and control system independently
developed by the company. It is seamlessly connected with various
types of Vickers Hardness Tester (including micro-Vickers), forming
a perfect set of automatic hardness measurement system.
The automatic hardness measurement is mainly used for measuring
Vickers hardness of various metals and some non-metallic materials.
It can measure hardness of all kinds of metal parts and parts after
thermal treatment. At the same time, it is suitable for the
determination of the depth of the effective hardening layer, the
coating layer and the heat affected position of the welding parts.
It can also be used to observe the internal metallographic
structure of various metal parts and to collect, display and print
images.
The system is especially suitable for measuring the surface
hardness of heat-treated workpiece, the distribution curve of
hardness gradient and the depth of effective hardening layer.
Technical parameters
1. The camera has a built-in 5 megapixels, and the image is clear.
2. operating system: Win 10

point, you can set the starting position of the straight line and
the location of the random movement, through the mouse click on the
automatic X-Y displacement platform carrier stage for 8 directions
of arbitrary movement control, speed can be adjusted, can
automatically reset, can be arbitrarily reset coordinate zero |
4. Measurement and control software
System description | Automatically complete continuous pressure, load keeping, reading,
data recording, by choosing a measurement method all measurement
will be automatically completed quickly; Select straight lines, zigzag lines, circles, arcs, random points,
matrices and self-learning modes according to different needs; Data
processing software is used to improve the readability of non-clear
indentation on non-smooth surface; The depth of hardened layer formed after continuous measurement of
the sample can be displayed in a table form. Can easily output all kinds of data measurement data, hardness
value table, hardening layer depth, maximum, average, minimum
value. |
Hardness Tester control | The hardness tester can be automatically controlled: automatic
turret (objective lens, indenter, objective lens automatic switch),
automatic loading, automatic measurement control You can set the brightness of the micro hardness tester's light
source Select the control objective for conversion and reflect in the
software interface to calculate parameter changes Select or start to control the durometer indenters automatically
into the load position, load, hold, unload and automatically back
to the measurement objective position The load set by the durometer can be automatically reflected on the
software interface |
Control object platform movement mode (Patten) | The software system can control the automatic loading platform for
programming and moving, which can be: 1) Measurement mode (Random A) Use this mode to suppress and read an optional point. 2) Measurement Mode (Random B) Measure and read any point. Rotates the selected coordinate
position at any Angle. 3) Transverse (X-axis direction) pressure and read 4) Longitudinal (Y axis direction) pressure and read 5) Measurement Mode (Line Set A) Use this mode to press and read the surface in an angular direction
(zigzag movement, i.e., the hardened layer depth measurement of the
broken line movement). 6) Measurement Mode (Line Set B) Use this mode for regular intervals of pressure and read. 7) Mobile programming methods such as trajectory coordinate
movement The above 8 lines can be set at the same time, each line can set
999 positions |
Measurement method | Automatic mode: automatic loading + automatic measurement +
automatic display of measurement results Optional manual mode measurement |
Image Acquisition/recognition method | Adopt high-quality and high-resolution cameras with a resolution of
12 million and large-size original image acquisition; A variety of
image compression methods are convenient to use (adopted images and
measurement results for storage format, image storage format BMP,
JPG and other common file formats). Automatic Vickers indentation measurement system adopts pixel
recognition technology, and analyzes indentation image through
special Vickers hardness indentation analysis software, and the
analysis software adopts digital image processing technology edge
segmentation algorithm to extract experimental indentation edge,
and then the method of extracting micro hardness indentation edge
is to analyze the sampling signal of the test indentation with the
wavelet multi-resolution theory, and to fit the indentation edge
line with the least square method, it can quickly and accurately
extract and automatically calculate the Vickers hardness value from
the indentation area of the Vickers hardness test of the
microstructure, and improve the readability of the non-clear
indentation on the non-smooth surface. |

The minimum indentation can be measured | About 5mm (automatic measurement) |
Minimum unit of measurement | 0.01mm |
Language | English |
Data output format/ Edit function | Inspection report can be customized according to user requirements; Through data processing software, the depth of hardened layer
formed after continuous measurement of the sample can be displayed
in the form of table. Can easily output a variety of measurement data, hardness value
table, hardened layer depth, maximum, average, minimum, display and
output color images with hardness value; Hardness value, hardness table, hardened layer depth chart, image
insertion and other data can be flexibly edited and printed in
"WORD" (optional "EXCEL") test report containing mathematical
statistics and hardened layer depth curve and saved (WORD format)
(optional "EXCEL"), also can print the observed sample topography
and save. The microstructure of indentation and background was
directly reflected, and metallographic analysis was made under
different magnification objective lens. |
