Description
Technical field
It the utility model is related to pulse reflection ultrasonic flaw detecting device technology, the constant ultrasonic wave inspection of especially a kind of pressure
Probing head.
Background technology
Pulse reflection ultrasonic examination technology is a kind of widely used conventional non-destructive method, is visited by ultrasonic wave
Hair penetrates ultrasonic wave and reaches measured workpiece and propagate within the workpiece, is reflected when running into defect or bottom surface, reflection echo is visited
Head is received, and the size and location of defect highly is judged according to position of the reflection echo on fluorescent screen and wave amplitude, is measured ultrasonic wave and is existed
The time that round trip is propagated between upper bottom surface calculates thickness of workpiece.To ensure defect location and the quantitative degree of accuracy, visit
Head is during workpiece surface slides scanning, it is necessary to which inspector keeps constant pressure to probe.
It is difficult to adopt automatic flaw detection device for structure and complex-shaped workpiece, usually using the side detected a flaw by hand
Formula, because the operating handle between different inspectors differs greatly, press the ripple that the pressure difference of probe can cause to gather signal
Width difference is very big, and ultrasonic probe of the prior art cannot be guaranteed that the pressure of different inspectors' pressing probes is identical, can not
Ensure that same inspector is remained during operation to constant pressure of popping one's head in, if the intensity of probe pressing greatly may be used
Probe can be caused to have different degrees of abrasion.Evaluation of these problems for defect has a great impact, the workpiece matter after detection
There is also very big hidden danger for amount.
Utility model content
The utility model is in nondestructive inspection ultrasound detection in the prior art, probe and work during testing staff's manual inspection
Part surface pressing is unmanageable and causes to detect the problem of inaccurate, there is provided a kind of constant ultrasonic detecting probe of pressure, with gram
Take above mentioned problem.
The purpose of this utility model is achieved in that a kind of constant ultrasonic detecting probe of pressure, including probe master
Body, the periphery of the probe body are arranged with ring-type neodymium nickel cobalt permanent magnet, end face and the ring-type neodymium of the probe body test side
The end face of nickel cobalt permanent magnet homonymy is concordant.
The constant ultrasonic detecting probe of pressure of the present utility model, during detection, operating personnel need to only promote from side
State probe and carry out scanning according to the detection path movement of setting, probe and the contact force of work piece interface by ring-type neodymium nickel cobalt forever
The Magnetic Control of magnet, a constant contact force can be kept, avoid operator and hold caused by control pressure inequality
Detection error.The constant ultrasonic detecting probe of pressure of the present utility model can be applied to the ultrasound detection of ferromagnetism cast(ing) surface
In.
Installation for ease of magnet and probe connects, and the ring-type neodymium nickel cobalt permanent magnet periphery is radially provided with some insertions
Screw, probe body position corresponding with screw is provided with bellmouth, the probe body and ring-type neodymium nickel cobalt permanent magnet
Fixed by the screw for screwing in screw, the tip of screw, which coordinates, to be headed into bellmouth.
For the size of further accurate control magnet, the sectional area of the probe body test side is S1, the ring-type neodymium
Nickel cobalt permanent magnet and the sectional area of the end face of test side homonymy are S2, the ring-type neodymium nickel cobalt permanent magnet and measured workpiece surface
Magnetic attracting force is F, then F × S2/ (S1+S2)=（25—30）.In this structure, above-mentioned formula, according to workpiece in detection with visiting
The size of head body contact area, it can rationally determine the sectional area of magnet, it is ensured that ultrasonic probe is constant with workpiece surface,
Meet the contact force of testing requirements.
Brief description of the drawings
Fig. 1 is the front view of the structure of the constant ultrasonic detecting probe of pressure of the present utility model.
Fig. 2 is Fig. 1 left view.
Embodiment
It is as depicted in figs. 1 and 2 the constant ultrasonic detecting probe of pressure of the present utility model, including probe body 1, visits
The periphery of head main body 1 is arranged with ring-type neodymium nickel cobalt permanent magnet 2, end face and the ring-type neodymium nickel cobalt permanent magnet 2 of the test side of probe body 1
The end face of homonymy is concordant；Installation for ease of magnet and probe connects, and being radially provided with for the periphery of ring-type neodymium nickel cobalt permanent magnet 2 is some
The screw 3 of insertion, probe body 1 are provided with bellmouth 6, probe body 1 and ring-type neodymium nickel cobalt permanent magnet with 3 corresponding position of screw
2 are fixed by screwing in the screw 4 of screw 3, and the end of screw 4, which coordinates, to be headed into bellmouth 6；For the chi of further accurate control magnet
Very little, the sectional area of the test side of probe body 1 is S1, and ring-type neodymium nickel cobalt permanent magnet 2 and the sectional area of the end face of test side homonymy are
S2, the magnetic attracting force on ring-type neodymium nickel cobalt permanent magnet 2 and measured workpiece surface is F, then F × S2/ (S1+S2)=（25—30）.
In this structure, above-mentioned formula, according to workpiece in detection and the size of probe body contact area, cutting for magnet can be rationally determined
Area, it is ensured that ultrasonic probe is constant with workpiece surface, meets the contact force of testing requirements.
The constant ultrasonic detecting probe of pressure of the present utility model, during detection, the data line 5 of probe is connected to
On supersonic detector, the state for meeting testing requirements is adjusted to, during detection, operating personnel only need to promote ultrasonic probe from side
Scanning is carried out according to the detection path movement of setting, the contact force of probe and work piece interface passes through ring-type neodymium nickel cobalt permanent magnet
Magnetic Control, a constant contact force can be kept, avoid operator's hand hold transducer control pressure it is unstable caused by
Detection error.The constant ultrasonic detecting probe of pressure of the present utility model can be applied to the ultrasound detection of ferromagnetism cast(ing) surface
