DETAILED DESCRIPTION

[0043] The present application is described in detail below with reference to embodiments, but the present application is not limited to these embodiments.

[0044] Example 1

[0045] A multi-mode ultrasonic testing device for composite materials, such as Figure 1-Figure 5 As shown, it includes a support frame 1, a trackless cylinder 2, a workbench 3, a motor 4, a one-way screw 5, a fixed block 6, an elastic rod 7, a torsion spring 8, an ultrasonic probe 9, a display screen 10 and a smearing mechanism 11. The left and right upper sides of the support frame 1 are connected to the trackless cylinder 2, the workbench 3 is connected between the sliders of the trackless cylinder 2, the upper right side of the workbench 3 is connected to the motor 4, the output shaft of the motor 4 is connected to the one-way screw 5, the one-way screw 5 is threadedly connected to the fixed block 6, the fixed block 6 is slidably connected to the workbench 3, the lower side of the fixed block 6 is connected to the elastic rod 7, the telescopic end of the elastic rod 7 is rotatably connected to the ultrasonic probe 9, a torsion spring 8 is connected between the ultrasonic probe 9 and the telescopic end of the elastic rod 7, a display screen 10 is connected to the left side of the workbench 3, an electric wire is connected between the display screen 10 and the ultrasonic probe 9, and a smearing mechanism 11 is provided on the fixed block 6.

[0046] like Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the apparatus further includes a coating mechanism. The coating mechanism 11 includes a coupling agent tank 111, a connecting tube 112, a nozzle 113, and a quick-release nozzle 114. The coupling agent tank 111 is clamped on the front and rear parts of the fixed block 6. The nozzle 113 is connected to the front and rear sides of the ultrasonic probe 9. Two rollers are rotatably provided on the nozzle 113 to facilitate uniform discharge of the coupling agent. The nozzle 113 is connected to the connecting tube 112. The nozzle 113 has a conical structure to facilitate spraying the coupling agent. The upper side of the connecting tube 112 is connected to the quick-release nozzle 114, and the quick-release nozzle 114 is clamped to the adjacent coupling agent tank 111.

[0047] When using the present invention, first place the support frame 1 in the ultrasonic detection area of the composite material, then contract the elastic rod 7 to move the ultrasonic probe 9 upward, and then place the composite material to be detected under the ultrasonic probe 9 on the workbench 3, and then make the elastic rod 7 rebound to drive the ultrasonic probe 9 to move downward so that the ultrasonic probe 9 fits the surface of the composite material. When the surface of the composite material is a complex curved surface, during the downward movement of the ultrasonic probe 9, the torsion spring 8 is deformed through the squeezing effect with the composite material, so that the ultrasonic probe 9 rotates, thereby making the ultrasonic probe 9 rotate and fit vertically to the surface of the composite material, so that the ultrasonic probe 9 reaches the optimal detection angle, and then start the ultrasonic probe 9 to emit ultrasonic waves to detect the composite material, and at the same time transmit the detection results to the display screen 10 for display, and then start the motor 4 to rotate the one-way screw rod 5, so that the fixed block 6 slides on the workbench 3, and at the same time start the trackless cylinder 2 to move the workbench 3, so that the composite material and the ultrasonic probe 9 move relative to each other. The ultrasonic probe 9 is moved, and under the action of the torsion spring 8, the ultrasonic probe 9 is attached to the surface of the composite material for scanning, thereby performing ultrasonic testing on the composite material. This automatically enables the ultrasonic probe 9 to detect the composite material, improving the detection efficiency, while ensuring that the ultrasonic probe 9 is perpendicular to the detection surface. While performing ultrasonic testing on the composite material, the nozzle 113 is activated, so that the coupling agent in the coupling agent tank 111 is sprayed on the composite material after passing through the connecting tube 112. At the same time, when the one-way screw 5 drives the fixed block 6 to move, the nozzle 113 moves, evenly spraying the coupling agent on the ultrasonic detection position on the composite material. Under the action of the coupling agent, the ultrasonic wave can more easily enter the interior of the composite material, while providing a certain lubrication effect, making the detection process smoother. When the coupling agent tank 111 needs to be replaced, it can be replaced through the quick-release head 114. This automatically sprays the coupling agent in front of the composite material for detection while performing ultrasonic testing on the composite material, thereby improving the ultrasonic testing effect.

[0048] like Figure 1 and Figure 10 As shown, it also includes a clamping mechanism 12, which includes a rotary handle 121, a bidirectional screw rod 122 and a splint 123. The front of the workbench 3 is rotatably connected to the bidirectional screw rod 122, and the left and right parts of the bidirectional screw rod 122 are both threadedly connected to the splint 123. The splint 123 is provided with a cushion to prevent wear of the composite material. The right side of the bidirectional screw rod 122 is connected to the rotary handle 121, and the rotary handle 121 is provided with a handle for easy rotation.

[0049] The clamping mechanism 12 of the device can be used to clamp and fix the composite material. After the composite material is placed on the workbench 3, the bidirectional screw rod 122 is rotated by the rotary handle 121. Under the action of the thread, the clamping plates 123 are moved closer to each other, so that the clamping plates 123 clamp and fix the composite material. This ensures that the composite material can be clamped and fixed when the composite material is tested, thereby avoiding affecting the ultrasonic testing quality of the composite material.
