Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, specifically a testing station for nondestructive testing of carbon fiber composite materials. Background Technology

[0002] CFRP uses carbon fiber as the reinforcing phase and resin as the matrix material. It has advantages such as light weight, high strength and corrosion resistance. It is widely used in aerospace, defense and military industry, rail transportation and other fields. Its mechanical properties (such as density, stiffness and fatigue characteristics) are key indicators for engineering structure selection. Therefore, it is necessary to evaluate the material quality and internal defects in real time through non-destructive testing technology.

[0003] Most existing devices for non-destructive testing of carbon fiber composite parts do not have the ability to fix the carbon fiber composite parts. Therefore, even a slight shaking during the test may cause a certain error in the non-destructive testing results. Therefore, we propose a testing table for non-destructive testing of carbon fiber composite parts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a testing station for non-destructive testing of carbon fiber composite materials, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A testing platform for non-destructive testing of carbon fiber composite materials, comprising two main blocks, a base plate fixedly installed between the two main blocks, a plurality of insertion holes formed inside the base plate, insertion rods inserted into the insertion holes, slots formed inside the insertion rods, insertion posts inserted into the slots, and rubber bands fixedly connected to the outside of the insertion posts. Square grooves are formed at the top of both main blocks. A motor is fixedly installed on one side of one main block. A first screw is rotatably connected to the two adjacent sides inside one of the square grooves. One end of the first screw passes through the main block and is fixedly connected to the output end of the motor. A sliding rod is fixedly connected to the two adjacent sides inside the other square groove. A moving block is threadedly connected to the outside of the first screw, and a moving block is slidably connected to the outside of the first screw. A connecting rod is fixedly connected between the two movable blocks. A sliding groove is provided inside the connecting rod, and a second movable block is slidably connected inside the sliding groove. A second motor is fixedly installed at the top of one of the movable blocks. Two mounting plates are fixedly installed at the top of the connecting rod, and a second screw is rotatably connected between the two mounting plates. One end of the second screw passes through one of the mounting plates and is fixedly connected to the output end of the second motor. The second screw is threadedly connected to the second movable block. When it is necessary to fix carbon fiber composite material parts of different sizes, simply insert a rubber band of appropriate length onto the insert rod. Then, the insert rod and the corresponding insertion hole can be used to fix the carbon fiber composite material using the rubber band. The first and second screws allow the probe to move omnidirectionally, making non-destructive testing more accurate.

[0006] Preferably, a detector is fixedly installed at the top of the connecting rod, a connecting plate is fixedly installed at the bottom of the second moving block, an electric push rod is fixedly installed at the bottom of the first connecting plate, a second connecting plate is fixedly installed at the output end of the electric push rod, a probe is fixedly installed at the bottom of the second connecting plate, a wire is fixedly connected to the outside of the probe, and the other end of the wire is fixedly connected to one side of the detector. When non-destructive testing of carbon fiber composite parts is required, the first motor drives the first screw to rotate, and the second motor drives the second screw to rotate, thereby allowing the probe to move in all directions. This process ensures a more comprehensive inspection of carbon fiber composite parts.

[0007] Preferably, a control panel is fixedly installed on one side of one of the main blocks.

[0008] Preferably, support legs are fixedly installed at the bottom ends of both main blocks.

[0009] Preferably, the first motor, the second motor, and the detector are all electrically connected to the control panel.

[0010] This invention provides a testing station for non-destructive testing of carbon fiber composite materials, which has the following advantages:

[0011] 1. This testing table for non-destructive testing of carbon fiber composite materials, through the setting of insert rods and rubber bands, can use the cooperation of slots and inserts to fix carbon fiber composite parts of different sizes and shapes by installing rubber bands of different lengths on the insert rods. The rubber bands will lose elasticity after long-term use, so they need to be replaced with new rubber bands. This setting can avoid the error in the test results caused by shaking during the test.

[0012] 2. This testing station for non-destructive testing of carbon fiber composite materials, through the setting of the first and second screws, only requires the operation of motor one and motor two to drive the probe to perform all-round non-destructive testing on carbon fiber composite parts. Through this process setting, it can be ensured that no test is missed, making the test results more accurate. Attached Figure Description

A sliding rod 25 is fixedly connected to the two sides of the part that are close to each other. The sliding rod 25 is used for limiting. A moving block 10 is threadedly connected to the outside of the first screw 9. The moving block 10 is slidably connected to the outside of the first screw 9. A connecting rod 12 is fixedly connected between the two moving blocks 10. A sliding groove 121 is opened inside the connecting rod 12. A moving block 2 15 is slidably connected inside the sliding groove 121. A motor 2 16 is fixedly installed at the top of one of the moving blocks 10. The motor 2 16 is used to drive the second screw 14 to rotate. Two mounting plates 13 are fixedly installed at the top of the connecting rod 12. The second screw 14 is rotatably connected between the two mounting plates 13 through a bearing. The second screw 14 is used to drive the moving block 2 15 to move.

Then, place the carbon fiber composite material part to be tested on the base plate 2. Next, insert the rubber band 6 onto the insertion rod 4. Based on the shape of the carbon fiber composite material part, insert the insertion rod 4 into the appropriate insertion hole 3. It is important to use the rubber band 6 to secure the carbon fiber composite material part until it does not move without external force. Then, non-destructive testing can be performed on the carbon fiber composite material part. The operator uses the control panel 23 to control motor 11 and motor 2 16. Motor 11 drives the first screw 9 to rotate, and motor 2 16 drives the second screw 14 to rotate, thus allowing the probe 20 to be placed on the carbon fiber composite material part. The probe 20 is moved to a suitable height using an electric push rod 18, allowing for comprehensive non-destructive testing of the carbon fiber composite parts. Coupling agent is applied as needed during the testing process. When a problem is detected, the result is first transmitted to the detector 22, which then transmits the result to the control panel 23. The staff then records the result. Because different carbon fiber composite parts vary in size when being fixed, different lengths of rubber bands 6 can be inserted into the push rod 4 based on the cooperation of the slot 5 and the insert 7, thus fixing carbon fiber composite parts of different sizes. Then, non-destructive testing can be performed using the above method. This is the working principle of this utility model.
