Description
Technical field
The present invention relates to a kind of metal detection technical fields, more particularly to a kind of easy to use, high degree of automation
Metal block surface hardness detection method.
Background technique
Hardness is one of evaluation most common index of metal material mechanics performance.The essence of hardness be material resist it is another compared with
The ability of hard material indentation.For being detected material, hardness is that represent the institute under certain pressure head and test force effect anti-
The comprehensive performance of a variety of physical quantitys such as the elasticity, plasticity, intensity, toughness and the wear resistance that mirror.It can due to passing through hardness test
To reflect the difference of metal material performance under different chemical components, institutional framework and heat treatment condition, therefore hardness
Test is widely used in the inspection of metallicity, supervises the development of heat treatment process quality and new material.
There are many instrument and equipment that measurement work uses, and every kind of instrument and equipment all influences it there are many unfavorable factor when in use
The accuracy of measured value.Herein only to two kinds of conventional instrument Rockwell apparatuses, Brinell hardness testers) when in use, it is easy to be detected
Some more typical influence factors that personnel ignore carry out specific aim analysis, and propose solution.
And existing hardness test instrument used at present, the degree of automation are lower, it is also necessary to pass through the various machinery such as micrometer
The measuring tool of formula is read, and that there are errors is big, speed is slow, the degree of automation is low, be unfavorable for the problems such as information processing, therefore compels
Be essential the design to be innovated.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the present invention provides a kind of metal block surface hardness inspection
Survey method has the Functional Design detected automatically, improves detection efficiency and detection accuracy, has saved manually, has had higher
Popularization and application value.
Technical solution: to achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of metal block surface hardness detection method, which is characterized in that including following operating procedure:
The sample of metal block to be measured is fixed in detection platform by step (1), and the hard detection pressure head of hardness tester is vertically right
The surface of metalloid block；
The driver of step (2), starting hard detection pressure head makes hard detection pressure head weight surface of the vertical compression to metal block, passes through
Displacement sensor detection hard detection pressure head is pressed into the depth on metal block surface；
Step (3), displacement sensor send depth information to controller module, and the fortune of hardness and depth is arranged in controller module
Relationship module is calculated, the hardness information obtained is passed to display screen by controller module；
The display screen being arranged in step (4), detection platform shows the hardness data of the detection position of metal block.
Preferably, hard detects the driver link control module of pressure head, according to control module in the step (2)
It issues instruction starting or closes.
Preferably, the pressure of hard detection pressure head applied to metal block is detected and is shown automatically in the step (2)
Show.
Preferably, voice announcer is arranged in the control module, Hardness results are broadcasted by voice mode.
Preferably, the display screen is liquid crystal display.
The utility model has the advantages that a kind of metal block surface hardness detection method provided by the invention, has the function of detecting automatically
Design, it is more humanized from practical angle.And the transmission information for realizing controller module and each detection module is quick
Transmitting, can be adapted to the batch detection of metal block, and the automatic detection for improving Metal Production is horizontal, while improve detection effect
Rate and detection accuracy have saved artificial, popularization and application value with higher.
Specific embodiment
