Abstract
The present invention relates to a kind of lossless hardness measuring device of hardened steel, including mounting box, signal generator and signal receiver are built-in with the mounting box, the signal generator and signal receiver connect emitter and receiving body outside mounting box by wire respectively, during detection, the emitter and receiving body are respectively placed in the both sides of tested part, and are contacted with the surface of tested part；After signal generator is powered with signal receiver, signal generator launches detection ripple and is transferred to tested part by emitter, after echo-signal is received by receiving body, is transferred to signal receiver；According to the corresponding relation between echo-signal and hardness number, the hardness of tested part is calculated.The present invention uses specific wavelength signal function when quenching part, and echo-signal has corresponding agreement relation with the hardness number of the part, so that the quick hardness number for correctly determining the part, and piece surface, without any damage, its is simple to operate.Simple structure of the invention, compared to traditional high-precision mechanical detection equipment, its is cheap, suitably promotes the use of.
Description
Technical field
The present invention relates to machining technology field, the New Hardness Testing Device of the tested part that more particularly to quenches.
Background technology
After tested part quenching, it usually needs carry out case hardness detection.It is main at present to use mechanical hardness detection method
Detection, the shortcoming that it is present substantially, detects cumbersome, fragile tested part surface, and the detection of general testing equipment is smart
Exactness is not high, according to high-precision testing equipment, then expensive, is unsuitable for promoting the use of.
The content of the invention
In view of the above-mentioned problems existing in the prior art, applicant is studied and is improved, there is provided a kind of hardened steel is lossless hard
Degree measurement apparatus and method, are realized using following scheme：
A kind of lossless hardness measuring device of hardened steel, including mounting box, be built-in with the mounting box signal generator and
Signal receiver, the signal generator and signal receiver connect emitter and reception outside mounting box by wire respectively
Body, the emitter and receiving body are placed in the both sides of tested part.
A kind of measuring method using the lossless hardness measuring device of above-mentioned hardened steel, including：By the emitter and reception
Body is respectively placed in the both sides of tested part, and is contacted with the surface of tested part；After signal generator is powered with signal receiver,
Signal generator launches detection ripple and is transferred to tested part by emitter, after echo-signal is received by receiving body, transmission
To signal receiver；According to the corresponding relation between echo-signal and hardness number, the hardness of tested part is calculated.
The technical effects of the invention are that：
The present invention uses specific wavelength signal function when quenching part, and echo-signal has corresponding with the hardness number of the part
Agreement relation so that the quick hardness number for correctly determining the part, and piece surface, without any damage, its is simple to operate.
Simple structure of the invention, compared to traditional high-precision mechanical detection equipment, its is cheap, suitably promotes the use of.

Specific embodiment
Specific embodiment of the invention is described further below in conjunction with the accompanying drawings.
As shown in figure 1, the lossless hardness measuring device of the hardened steel of the present embodiment, including * long * wide it is high=300mm*200mm*
The mounting box 1 of 200mm, is built-in with signal generator 2 and signal receiver 3 in mounting box 1, signal generator 2 and signal are received
Device 3 connects emitter 4 and receiving body 5 outside mounting box 1 by wire respectively, and emitter 4 and receiving body 5 are placed in tested part
100 both sides.
The measuring method of the utilization lossless hardness measuring device of above-mentioned hardened steel of the present embodiment, including：By emitter 4 and connect
Acceptor 5 is respectively placed in the both sides of tested part 100, and is contacted with the surface of tested part 100；Signal generator 2 connects with signal
Receive after device 3 is powered, signal generator 2 launches detection ripple and is transferred to tested part 100 by emitter 4, echo-signal by
After receiving body 5 is received, signal receiver 3 is transferred to；According to the corresponding relation between echo-signal and hardness number, calculate tested
The hardness of part.
By taking the hardened steel hardness inspection of part as shown in Figure 2 as an example：
Measurement part name：Duplicate gear
Measurement part material：40Cr
Measurement part heat treatment method：Quenching
Measurement process：Measurement apparatus are opened, is switched on power, emitter 4 is placed in upper wheel inner surface, receiving body 5 is placed in
Wheel correspondence outer surface, opens switch, observation and record identifier receiver signal.
Measurement result：Echo frequency 23.71KHz, hardness number 50.5HRC.
Note in measurement process：Change emitter simultaneously and receive body position, can be with measurement surface uniformity of hardness.
In the present invention, the tranmitting frequency of emitter is fixed frequency, and the difference according to echo frequency determines the hard of part
Angle value；Wherein, the relation between echo frequency and hardness number, is demarcated by standardized element.
Embodiment provided above is better embodiment of the invention, only for the convenient explanation present invention, not to this hair
It is bright to make any formal limitation, any those of ordinary skill in the art, if putting forward skill the present invention is not departed from
In the range of art feature, using the Equivalent embodiments locally changed done by disclosed technology contents or modify, and
Without departing from technical characteristic content of the invention, still fall within the range of the technology of the present invention feature.
