Description
Technical field
The present invention relates to a kind of ultrasonic probe of automatic filling couplant, belong to field of non destructive testing.
Background technology
The implication of NDT and NDE：In the case of not defective work piece, using the various methods such as sound, light, electricity, magnetic come
Whether there is defect or inhomogeneities in detection checked object, provide the information such as size, position, property and the quantity of defect, enter
And judge the general name of all technological means of state of the art residing for checked object (such as whether qualified, residual life).
Ultrasound examination is the physical characteristics such as propagation using ultrasonic wave in object, reflection and decay finds defect
A kind of lossless detection method.It is mainly for detection of metal material and the internal flaw of part nonmetallic materials.Ultrasonic examination
With low cost, easy to operate, the detection outstanding advantages such as thickness is big, harmless to human and environment.
Ultrasonic wave can be divided into conventional (one) contact method into the mode of examined workpiece：The liquid that ultrasonic probe passes through thin layer
Body or fluid coupling medium are directly contacted with the test surface of examined workpiece.(2) immersion method：It is primarily referred to as using water as coupling
Medium, it is water seaoning to be commonly called as, and the ultrasonic wave that ultrasonic probe sends enters back into examined workpiece by certain thickness water layer, ultrasound
Ripple probe is not contacted with examined workpiece
During without automatic filling device, the difficulty that conventional detection runs into：
1st, for contact method, it is necessary to first get out corresponding fluid coupling medium, and be coated in for couplant manually by needs
On examined workpiece, exist and smear uneven, it is less efficient；
2nd, for immersion method, it is necessary to measured piece is infiltrated in water environment, water environment is formed slowly, and take a large amount of empty
Between, efficiency is low.
The content of the invention
It is an object of the invention to provide a kind of ultrasonic probe of automatic filling couplant, the probe can quickly give voussoir
Coupling environment is provided with examined workpiece surface, it is ensured that the high-efficient simple of measurement process.
The present invention is completed by the following technical programs：
Shang Gai of the present invention, lower annular seal space, Shang Gai are fixedly connected with lower annular seal space, between depression bar is installed, depression bar is close with
Envelope is fixed with spring between chamber, and depression bar lower end is fixedly connected with ultrasonic sensor with voussoir, and ultrasonic sensor exists with voussoir
Can be freely up and down movable in lower annular seal space, lower annular seal space is fixedly connected with sealing gasket, and lower annular seal space is communicated with couplant pipeline.
The depression bar applies pressure, and when compressing completely, the basal surface of voussoir exceeds and sealing bottom surface.
The lower annular seal space top is provided with through hole.
When depression bar of the present invention applies pressure, when spring is compressed completely, coupling process only needs to control depression bar and presses to bottom,
The basal surface of voussoir is directly contacted with examined workpiece surface, coupling agent feeding device work, is quickly visited with ultrasound to voussoir
Head builds coupling condition, improves operating efficiency；And constitute simple structure.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Embodiment 1
The present invention is used for the ultrasonic probe of automatic filling couplant, and upper lid 2 is fixedly connected with lower annular seal space 4, and upper lid 2 is with
The middle part of annular seal space 4 is respectively equipped with the mounting hole of depression bar 1, and the depression bar 1 being placed in lid 2 is provided with baffle plate, baffle plate and lower annular seal space 4 it
Between depression bar 1 on be fixed with spring, the top of the lower end of depression bar 1 in lower annular seal space 4 and voussoir 6 is fixedly connected, and the top of voussoir 6 also sets
There is ultrasonic sensor 9, voussoir 6 can freely up and down be moved in the presence of depression bar 1 in lower annular seal space 4；The lower bottom of annular seal space 4
Fixed installation sealing gasket 5 is provided with, the top of lower annular seal space 4 is provided with through hole, and side wall is provided with the hole for installing couplant pipeline 7；Coupling
Agent pipeline 7 is connected with coupling agent feeding device.
The method that detection is detected workpiece residual stress and defect, as follows by linear electric motors or other dresses that move linearly
Put and be connected with depression bar 1, linear electric motors or other linear moving apparatus promote depression bar 1 to move down, until sealing gasket 5 with it is tested
Survey after workpiece surface is contacted and stop moving down, now inject couplant in the coupling downward annular seal space 4 of agent feeding device.Work as couplant
When being covered with detected workpiece surface, stop couplant injection, continue lower moulded rod 1, during depression bar 1 is moved down, voussoir 6
Move down, after spring 3 is compressed completely, depression bar 1 cannot continue to move down, voussoir 6 is apart in close contact with detected workpiece surface, it is real
Coupling process is showed.Ultrasonic detection equipment is opened, carries out detection process.
