Description

Technical Field

[0001] This utility model relates to the field of carbon fiber material testing technology, specifically a non-destructive testing device for carbon fiber composite materials. Background Technology

[0002] Carbon fiber refers to high-strength, high-modulus fibers with a carbon content of over 90%. It boasts the highest heat resistance among all synthetic fibers. Carbon fiber composite pipes are also made of carbon fiber; these pipes, also known as carbon fiber tubes or simply carbon pipes, are produced by pre-impregnating carbon fiber composites with styrene-based polyester resin and then heating, curing, and pultruding them.

[0003] According to application number CN202321270533.2, a non-destructive testing device for carbon fiber tubes is proposed, which facilitates the testing of different positions of carbon fiber tubes, reduces blind spots, and improves the testing accuracy of carbon fiber tubes. It includes a base and a support, with the support mounted on the front top of the base. It also includes a drive device, a support device, support shafts, multiple sets of support wheels, a connecting plate, a testing probe, and a display. The left and right ends of the two sets of support shafts are rotatably mounted on the inner sidewalls of the support, and the two sets of support shafts are arranged opposite each other. The drive device is mounted on the support and drives the rotation of the two sets of support shafts. The multiple sets of support wheels are respectively fitted onto the outer sidewalls of the two sets of support shafts. The connecting plate is positioned above the two sets of support shafts via the support device, which is used to drive the connecting plate to rise, fall, and move left and right. The testing probe is mounted at the bottom of the connecting plate. Before testing, the testing head needs to be coated with a coupling agent on the material. However, this application lacks a structure for automatically applying the coupling agent to the material, requiring manual application, which is inefficient. Furthermore, the position of the support shafts in this application cannot be adjusted, making it impossible to adjust for carbon fiber tubes of different diameters. Therefore, we propose a non-destructive testing device for carbon fiber composite materials. Utility Model Content

The sliding of the second slider moves a support column, which in turn adjusts the lateral position of the side plate. After adjustment, a third electric telescopic rod is activated to move an adjusting plate, followed by the activation of the second electric telescopic rod to move the top plate. This causes the sealing extrusion plate to slide and extrude inside the storage box, spraying coupling fluid onto the outside of the carbon fiber composite pipe.

Starting the second motor drives the connecting shaft to rotate, which in turn drives the first inner roller to rotate. The rotation of the first inner roller, in turn, drives the first outer roller to rotate, allowing for the adjustment of the carbon fiber tube angle. When adjusting the position of the first outer roller, starting the first electric telescopic rod moves the side block, and the movement of the second outer roller pulls the first outer roller back, completing the adjustment and reducing limitations in its use.

[0024] Two first mounting plates 3 are mounted on one side of the second mounting plate 15. A third sliding groove 33 is formed inside each of the two first mounting plates 3. A directional roller 37 is rotatably connected to one side of each first mounting plate 3 via a bearing. A first inner roller 11 is slidably connected inside the third sliding groove 33. Starting the second motor 9 drives the connecting shaft 10 to rotate, which in turn drives the first inner roller 11 to rotate. A first outer roller 12 is fixedly sleeved on the outside of the first inner roller 11. Rotation of the first inner roller 11 drives the first outer roller 12 to rotate, allowing adjustment of the angle of the carbon fiber tube. A toothed belt is provided on the outside of the first outer roller 12. A fourth sliding groove 34 is formed inside the first mounting plate 3. A third slider 35 is slidably connected inside the fourth sliding groove 34. The second inner roller 13 is rotatably connected to the third slider 35. Two first sliding grooves 6 are formed on the top of the mounting base 1. A first slider 7 is slidably connected inside each of the two first sliding grooves 6. Multiple threaded holes are formed on the outside of the mounting base 1, and limiters are installed inside the threads of these threaded holes. Bolts and limit bolts are fitted inside the first slider 7. By tightening the limit bolts, the first slider 7 can be limited to ensure stability. A movable plate 8 is installed on the top of each of the two first sliders 7. A second motor 9 is installed on one side of the movable plate 8. The output end of the second motor 9 is fixedly connected to a connecting shaft 10. The connecting shaft 10 is fixedly connected to one of the first inner rollers 11.

A first electric telescopic rod 5 is installed on the top of the mounting base 1. A side block 4 is fixedly connected to the output end of the first electric telescopic rod 5. A second inner roller 13 is rotatably connected to one side of the side block 4. A second outer roller 14 is fixedly sleeved on the outside of the second inner roller 13. The second outer roller 14 is connected to the first outer roller 12 and the directional roller 37 through a toothed belt. When adjusting the position of the first outer roller 12, the first electric telescopic rod 5 is activated to drive the side block 4 to move. The movement of the second outer roller 14 pulls the first outer roller 12 back, completing the adjustment work.

[0025] In summary, when using this carbon fiber composite material non-destructive testing device, the operator first activates the second electric telescopic rod 24 to lift the sealing extrusion plate 30 out of the rotating groove 32, and then injects coupling agent into the rotating groove 32.

[0026] After injection, the first electric telescopic rod 5 is activated to move the side block 4. The movement of the side block 4 moves the second outer roller 14, which can pull back the first outer roller 12. During the pullback of the first outer roller 12, the first slider 7 slides inside the first slide groove 6. The position of the connecting shaft 10 can be adjusted by moving the moving plate 8 to complete the adjustment work. The second motor 9 is activated to rotate the connecting shaft 10. The rotation of the connecting shaft 10 drives the first inner roller 11 to rotate. The rotation of the first inner roller 11 drives the first outer roller 12 to rotate, thus completing the angle adjustment work.

[0027] After adjustment, the first motor 2 is started to drive the lead screw 31 to rotate. The rotation of the lead screw 31 drives the second slider 16 to move. The sliding of the second slider 16 can drive the support column 17 to move. The movement of the support column 17 can adjust the lateral position of the side plate 23. By sliding the sliding sleeve 28 on the outside of the support column 17, the vertical position of the side plate 23 can be adjusted. The limiting bolt 29 can be used to limit the sliding sleeve 28.

[0028] The third electric telescopic rod 27 is activated to move the adjusting plate 20. Then, the second electric telescopic rod 24 is activated to move the top plate 25, which in turn causes the sealing extrusion plate 30 to slide and extrude inside the storage box 36, spraying the coupling liquid onto the outside of the carbon fiber composite pipe. After the coating is completed, the coupling agent is spread with the help of the scraper 18 on one side. Then, the detection head 21 is brought close to the carbon fiber composite pipe to adapt to the curved surface and release ultrasonic waves. Then, the piezoelectric composite material set inside the probe will generate an electric charge due to mechanical vibration, converting the sound wave energy into an electrical signal. Finally, the staff receives the electrical signal and images it through the detection equipment to complete the detection of the carbon fiber composite pipe.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
