Description
Technical field：
The present invention relates to ultrasonic detecting equipment field, relate in particular to a kind of from coupling ultrasonic detecting probe dress
Put.
Background technology：
Ultrasonic detection technology is one of conventional Dynamic Non-Destruction Measurement.With the development of Dynamic Non-Destruction Measurement, ultrasonic wave
Detection technique is because its sensitivity is high, speed is fast, low cost, it is harmless the features such as, be widely used in pressure vessel, petroleum pipeline
The quality testing link in the fields such as line, machine components.Ultrasonic probe is the device of transmitting and received ultrasonic signal.Surpassed
Air meeting interference signal transmission during sonic detection between probe and workpiece, reduces the accuracy of detection, therefore need to be soaked with water
Probe and workpiece, the air for excluding between the two make it have preferable coupling effect.The hand-held spy of staff in detection process
Head is in workpiece surface motion, and the power being applied on probe is uniform and stable, firmly too small to easily cause coupling effect difference and then shadow
The accuracy of detection is rung, or even causes the missing inspection of some fine defects, the organic glass of detecting head surface can be caused if firmly excessive
The accelerated wear test of glass, shortens probe service life.Above procedure inconvenient operation, efficiency is low, detection accuracy susceptible.
The content of the invention：
The purpose of the present invention is aiming at disadvantages described above, there is provided a kind of simple to operate, and monitoring efficiency is high to be surpassed from coupling
Acoustic detection probe device.
To achieve the above object, the present invention proposes following technical scheme：
A kind of coupling ultrasonic detection probe device certainly, including support member and rolling member, the support member include
Support, tank, hollow shaft and nut, the tank are installed on the support top, and the hollow shaft passes through the pedestal lower end
And fastened by the nut two ends, the rolling member includes probe, two sealed bearings, plectane and rubber membrane, the spy
Head is installed in the hollow shaft, and between two sealed bearings, the sealed bearings are embedded in the plectane circle centre position, and
In the hollow shaft, the rubber membrane is coated between two blocks of plectanes, and it is empty internally to form sealing in two blocks of plectanes
Between, the probe connects supersonic reflectoscope by wire.
Couplant is filled with the sealing space, the probe lower end is immersed in couplant.
The bottom of gullet offers square opening, and the pedestal upper end face equally offers square opening, and the plectane is passed through
The square opening.
The wire is passed from the center of the hollow shaft.
The aperture of the square opening has more than the distance between two blocks of plectanes, and between the hole wall and plectane of the square opening
There are 1~3mm gaps.
One layer of water-absorbing sponge for preventing water from being flowed out from gap is provided between the tank lower surface and pedestal upper end face.
The beneficial effects of the invention are as follows：Disclosed is a kind of from coupling ultrasonic detection probe device, will pop one's head in
It is dipped in couplant, while being soaked by water outside rubber membrane, the interference of air is excluded completely, coupling effect is more preferable；During detection, rolling
Dynamic part rolls in workpiece surface and replaces probe to be slided in workpiece surface, probe is preferably protected, while avoiding probe
The phenomenon of discontinuity, makes operation more facilitate and improves detection accuracy.
Brief description of the drawings：
Fig. 1 is structural representation of the invention；
Fig. 2 is schematic perspective view of the invention；
Fig. 3 is top view of the invention.
