Embodiment 1

[0057]SeeFigure 1-3 , An ultrasonic automatic detecting device of an irregular surface workpiece comprising a work bench 1, and the support belt 2 is fixedly mounted on the working bench 1, and the first servo motor 3 is fixedly installed on the upper surface side of the working bench 1. The output shaft of the first servo motor 3 is fixedly connected to the drive roller of the conveyor belt 2; the upper surface of the working bench 1 is adjacent to the first servo motor 3 side fixed to the first mounting frame 4, and the top end of the first mounting frame 4 is fixed. The first fixed crossbar 5, the lower end of the first fixed cross rod 5 fixedly connected to the array laser sensor 6; the working gear 1 is fixed from one end of the first mount 4 fixed to the second mount 7, the second mounting frame The top end of the 7 is provided with a second servo motor 8, and a second fastening cross rod 9 is fixed to the second fastener motor 8, and an ultrasonic detection mechanism 14 is co...

Embodiment 2

[0064]SeeFigure 4 The basis of the first embodiment is different in that an ultrasound automatic detection method of an irregular surface workpiece is applied to an ultrasound automatic detecting device of an irregular surface workpiece according to claims 1-5, including the following step:

[0065]S1, the workpiece clamp 12 is placed between the workpiece clamp 12 on the conveyor belt 2;

[0066]S2, start the first servo motor 3, and the conveyor belt 2 is active, and the workpiece 13 to be detected is uniformly passing from the array laser sensor 6;

[0067]S3, the distance signal to be detected by the array laser sensor 6 obtains each point of the surface of the workpiece 13 is formed, and the shape signal to be detected by the surface of the workpiece 13 is formed;

[0068]S4, transmit the distance signal and shape signal obtained by the array laser sensor 6 to the control module, the filter unit of the control module performs filtering the received distance signal and the shape signal, and...

Embodiment 3

[0072]SeeFigure 5-7Based on Example 1-2 but there is a difference in that the three-dimensional coordinate system is established by the ultrasonic detecting mechanism 14 of the ultrasonic automatic detecting device of the irregular surface workpiece, and the first electric push rod 10 is the Z-axis ( Up and down) positive direction, the vertical Z axial is the X-axis (front and rear) positive direction, vertical Z, X axial left is the Y-axis (left and right) positive directions;

[0073]The control module first controls the first servo motor 3 to control the shape signal to be detected by the array laser sensor 6, and the array laser sensor 6 to the working gear 1 is defined. The control module receives the shape signal of the array laser sensor 6, which generates the control signal of the entire detection process according to the distance difference of the different positions, to control the first servo motor 3, the second servo motor 8, the first electric push rod 10 , The second ele...

Abstract

The invention discloses an ultrasonic automatic detection device and method for an irregular curved surface workpiece, and belongs to ultrasonic detection devices and methods. An ultrasonic automatic detection device for an irregular curved surface workpiece comprises a workbench frame, a conveying belt is fixedly installed on the workbench frame, a first servo motor is further fixedly installed on one side of the upper surface of the workbench frame, and an output shaft of the first servo motor is fixedly connected with a driving roller of the conveying belt. The top end of a first mounting frame is fixedly connected with a first fixed cross rod, and the lower end of the first fixed cross rod is fixedly connected with an array type laser sensor. A second mounting frame is fixedly connected to the end, away from the first mounting frame, of the top surface of the workbench frame, a second servo motor is arranged at the top end of the second mounting frame, a second fixed cross rod is fixedly connected to the second servo motor, and an ultrasonic detection mechanism is connected to the second fixed cross rod. The problem that the reliability of detection data is affected due to the fact that an existing design cannot be well competent for ultrasonic detection work of irregular curved surface workpieces is effectively solved.

Description

Technical field[0001]The present invention relates to ultrasonic detecting devices and methods, specifically an ultrasound automatic detecting apparatus and method for irregular curved workpieces.Background technique[0002]Ultrasound detection is to determine the inside of the test material and the workpiece by observing the characteristics of ultrasonic wave refraction, reflection, diffraction, attenuation, resonance, etc. And whether there is a defect in the surface, thereby evaluating the quality and use value without destroying or not impairing the quilt and the workpiece.[0003]For ordinary surface flat workpieces, you can directly use the ultrasonic probe hover to contact the workpiece with the coating surface, but for irregular surface workpieces, existing ultrasound detecting devices cannot accurately and good test work. In order to better adapt to ultrasonic detection of irregular curved workpieces in order to better adapt to ultrasonic testing of irregular surface workpieces...
