Degree；(2) same point is focused to by design ultrasonic probe 40908 and laser 40909, it can be by demarcating bilateral laser
40909 focus positions judge the position of bilateral ultrasonic probe 40908；Because ultrasonic wave naked eyes are invisible, pass through naked eyes
Visible obvious phenomenon, so that it is guaranteed that the primary condition of information collection；When bilateral laser 40909 focuses on same point, i.e.,
It can determine whether that the position of 40908 send-receive signal of bilateral ultrasonic probe also focuses on phase same point, may be implemented to emit/connect
The information collection of receipts.
Referring to shown in Fig. 1 to Figure 11, the course of work of the utility model is as follows:
Since this experimental provision comprehensive comparison is strong, the more detailed specifically used process for introducing the device,
It receives C scanning, R wave scanning and guided wave scanning from single probe C scanning, dual probe transmitting individually below and is introduced, and with
Upper function is all the cutting edge technology means of Ultrasonic Nondestructive；Since the apparatus function is powerful, and there is symmetrical ultrasound
Detection part, in order to more clearly describe the use operation of the device, it is necessary to which the initial position of the device is described；
Due to needing couplant during ultrasound examination, all detection environment of the present apparatus are all with water for detection medium；
The initial position of the device: as shown in Figure 10, the as initial position of the device；It is high-precision in the device at this time
Spend the X, Y, Z axis non-displacement movement in XYZ axial displacement platform 2,1/4 arc of bilateral in symmetrical scanning equipment 409 at this time
Guide rail 40907 necessarily is in concentric position, and the rotation angle of bilateral fixture assembly (as shown in Figure 8) can be any (due to each
The ultrasonic probe 40908 of a fixture assembly and the axis of laser 40909 all point to the center of circle of 1/4 arc-shaped guide rail 40907,
Therefore the rotation angle of fixture assembly does not influence the focusing of bilateral laser 40909), and meet the laser 40909 of bilateral
The point of focusing is same point；The i.e. bilateral ultrasonic probe 40908 of send-receive probe only can be just determined in this case
Collection point is same point, and the public domain that the two acquires information is maximum, it is possible to reduce in collection process due to public domain is small,
Experimental phenomena is unobvious and bring error；When line rail 406 is mobile to Y-axis, that is, when carrying out R wave scanning and guided wave scanning,
Guarantee that send-receive probe acquisition signal is straight line, meets the primary condition of signal acquisition, can just start normal use should
Device；
It is shown in Figure 9, the schematic three dimensional views be unilateral side C scanning schematic diagram, detection be horizontal plate face cross section information；
What it is due to C scanning detection is the cross section information vertical with ultrasonic probe, and ultrasonic probe must be perpendicular to measured surface；
Here for moving the ultrasonic probe in scanning equipment 409a, in order to avoid interference, the Y by control line rail 406 is needed
To displacement, mobile scanning equipment 409a is moved to suitable position, then angle is rotated by disc type electric machine 40911 and to move
Ultrasonic probe 40908 in scanning equipment 409a is perpendicular to horizontal plane, to be detected；Due to the high-precision in the present apparatus
XYZ axial displacement platform 2 can provide the movement of any position under the state, therefore can detect any position according to experiment demand
The cross section information set, and can pair cross-section information be acquired processing；If using the ultrasound in fixed scanning equipment 409b
Wave probe 40908 carries out scanning, and operation is similarly；
Shown in Figure 10, dual probe transmitting receives C scanning and is accomplished that the scanning to vertical plate face cross section information, herein
In the case of kind, in order to guarantee ultrasonic probe perpendicular to the surface of test specimen, it would be desirable to use the ultrasonic probe of L-type；
It is still to meet the primary condition of initial position first, so that the laser 40909 of bilateral focuses on same point, then makes line rail
406 move suitable distance along Y-axis, and then the disc type electric machine 40911 of bilateral starts to rotate, so that the ultrasonic probe of bilateral
40908 detection part is perpendicular to measured surface, then passes through high-precision XYZ axial displacement platform 2 to the title formula scanning under the state
Device 409 is moved on measured piece surface, to detect the cross section information of test specimen different location；
Shown in Figure 11, which is the schematic diagram of R wave and guided wave inspection, a) is wherein partially that R wave inspection is shown
Be intended to: at this time on the basis of initial position, line rail 406 needs mobile scanning equipment 409a movement being moved to behaviour along Y-axis
The position of author designed, the fixture assembly for rotating bilateral by bilateral disc type electric machine 40911 is (as shown in Figure 8) to arrive identical angle
Degree (bilateral ultrasonic probe rotation angle is symmetrical about plumb line at this time), when the angle of send-receive ultrasonic probe 40908
When reaching Rayleigh angle, R wave can be formed on tested part surface, the distance of detection is by the displacement of line rail 406 processed come real
It is existing, when high-precision XYZ axial displacement platform 2 carry out X, Y-direction movement when, may be implemented to measured piece any position surface residual
The detection of the information such as stress；
Referring to the b in Figure 11) shown in part, when device becomes Guided waves state by original state, working principle
It is identical as R wave, the difference is that the angle that disc type electric machine 40911 rotates is different, the wave for causing ultrasonic wave to generate measured piece
Shape is different, therefore guided wave scanning is that the detection angles of ultrasonic probe 40908 are different from the essential distinction of R wave scanning；When double
The angle for sending out send-receive ultrasonic probe 40908 in fixture assembly is rotated to guided wave by the disc type electric machine 40911 of side
When angle (at this time bilateral ultrasonic probe rotation angle symmetrical about plumb line), can inside to measured piece any position it is residual
The information such as residue stress are detected.
The foregoing is merely the preferred embodiments of the utility model, are not intended to limit the utility model, for ability
For the technical staff in domain, various modifications and changes may be made to the present invention.It is all to made by the utility model it is any modification,
Equivalent replacement, improvement etc., should be included within the scope of protection of this utility model.
