Description of the drawings
Fig. 1 is the schematic diagram of an embodiment of the present invention；
Fig. 2 is a kind of embodiment schematic diagram for being furnished with mobile platform of the present invention.
Specific embodiment
As shown in Figure 1：A kind of electromagnetic acoustic automatic flaw detection device, including probe cover 10, the electricity in probe cover 10
Magnetic ultrasonic transducer 15 and detection control circuit system 19, the afterbody of electromagnet ultrasonic changer 15 is connected to tooth bar 16, described tooth bar
16 driven by servomotor 18 under gear 17 drive after, can control electromagnet ultrasonic changer 15 probe cover 10 sensing passage
Stretch in 14；There is range finding head in probe cover 10, range finding head is to perceive probe cover and workpiece for measurement surface distance, and sensor is surveyed
The distance signal for obtaining is detected control circuit system and receives, and head of finding range in embodiment includes the compression being arranged in elastic cavity 11
Spring 12, the contact head 13 of the bottom of compression spring 12, and the touched 13 slip variable resistors for driving.The bottom of compression spring 12
Contact head 13 be close to the surface of workpiece for measurement under the tension force of compression spring 12, contact head 13 is flexible in elastic cavity 11
Distance is that the voltage signal produced after resistance variations on the slip variable resistor of the drive of contact head 13 comes equivalent.The distance signal
After passing to detection control circuit system 19, by software programming, by the translational speed of workpiece for measurement 3 or the mobile speed of device
Degree integrates the spacing between range finding head and electromagnet ultrasonic changer 15, provides certain delay control signal control servomotor 18
Rotation.The height and position on the surface of the workpiece for measurement 3 that head of so finding range is measured can just wait until that electromagnet ultrasonic changer 15 is moved
It is flexible by the driving structure control of gear 17 and tooth bar 16 during to the position, realize electromagnet ultrasonic changer 15 and workpiece for measurement 3
The height gap on surface be maintained in the efficient working range of 2 ~ 5mm.
Additionally, the variable variable resistance of sliding can also be substituted for laser ranging probe costly by range finding head.Laser ranging is visited
Head, is the instrument for carrying out Accurate Determining to the distance of target using laser.Laser range finder operationally projects a branch of to target
Very thin laser, by photoelectric cell the laser beam of target reflection is received, and timer determines laser beam from the time for being transmitted into reception,
Calculate from observer's range-to-go.
When workpiece for measurement is not easy to move, when checking using the hand-held device, range finding head and electromagnetic acoustic can be ignored
Spacing between transducer 15, therefore the distance value that range finding head is measured directly controls the flexible of electromagnet ultrasonic changer 15.
And when realizing Aulomatizeted Detect, as long as allowing velocity amplitude to be set in detection control circuit system 19, and arrange in pairs or groups one
Mobile platform just can be with.As shown in Fig. 2 the device is coordinated by support 2 being arranged on detection bed, detection bed includes mobile platform
20, the clamping device 21 on mobile platform 20.Mobile platform is common XY twin shaft mobile platforms, the mobile platform 20
