Description

Technical Field

[0001] This utility model relates to the field of composite material testing technology, specifically to a non-destructive testing fixture for composite material structural components. Background Technology

[0002] Composite materials, with their superior properties such as high strength, lightweight, and corrosion resistance, are widely used in many fields such as aerospace, automobiles, and ships. In the production, manufacturing, use, and maintenance of composite structural components, non-destructive testing is a key link to ensure their quality and safety. Currently, existing non-destructive testing tooling usually requires clamping devices to fix structural components when testing them. However, existing clamping devices can only stably clamp structural components of a single shape, making it difficult to adapt to various irregularly shaped composite structural components. Their application range is narrow and their versatility is insufficient.

[0003] As disclosed in the prior art, Chinese utility model publication CN222420099U discloses an ultrasonic non-destructive testing fixture for composite materials. This utility model includes a base, with movable grooves formed in the middle of the top two sides of the base. Two sets of movable grooves are fitted with bidirectional threaded rods on their inner sides. Internal threaded blocks are threaded to the outer sides of the bidirectional threaded rods on both sides. Movable plates are provided at the top of each set of internal threaded blocks. Guide rods are fitted at the top and bottom of one side of each movable plate. A side clamping plate is provided on one side of both sets of guide rods. The top of one side of the side clamping plate... The top and bottom are provided with sliding grooves, and sliders are slidably connected to the inner sides of the two sets of sliding grooves. An inner clamping plate is provided on one side of the two sets of sliders. In the above structure, the composite material is clamped and fixed by the inner clamping plate. However, the inner clamping plate is arc-shaped, and the clamping method of the side clamping plate is more suitable for tubular structures. It cannot effectively clamp and fix composite material structural parts of other shapes, which can easily cause the structural parts to shift or shake during the inspection process. That is, there is a problem that the above clamping parts are not versatile enough and cannot be adapted to structural parts of various shapes. Therefore, we need to propose a non-destructive testing fixture for composite material structural parts. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A non-destructive testing fixture for composite material structural components includes: a base 1, with two sets of support seats 2 symmetrically arranged on the top of the base 1, and mounting seats 3 fixedly fixed on the top of the two sets of support seats 2 respectively, and mounting grooves 4 respectively opened on the opposite side of the two sets of mounting seats 3; two sets of snap-fit ​​seats 5, with clamping seats 6 fixedly installed on the opposite side of the two sets of snap-fit ​​seats 5, and snap-fit ​​mechanisms 7 for quick snap-fit ​​with mounting seats 3 respectively provided inside the two sets of snap-fit ​​seats 5, and disassembly mechanisms 8 for quick disassembly of snap-fit ​​seats 5 respectively provided on both sides of the two sets of mounting seats 3.

[0025] In this embodiment, the basic structure of the tooling is constructed by setting a base 1, a support base 2, a mounting base 3, a snap-fit ​​base 5, a clamping base 6, a snap-fit ​​mechanism 7, and a disassembly mechanism 8. The snap-fit ​​mechanism 7 and the disassembly mechanism 8 work together to realize the quick installation and disassembly of the clamping base 6 and the mounting base 3. This facilitates the flexible replacement of the appropriate clamping base 6 according to the shape of the composite material structural part to be tested, effectively solving the problem that traditional tooling can only adapt to structural parts of a single shape. This improves the versatility of the tooling for structural parts of multiple shapes and provides a stable fixed foundation for non-destructive testing.

[0026] The snap-fit ​​mechanism 7 includes two sets of storage slots 71, two sets of irregular blocks 72, two sets of elastic elements 73, and two sets of snap-fit ​​grooves 74; the snap-fit ​​base 5 has storage slots 71 on both sides for the irregular blocks 72 to slide, the two sets of elastic elements 73 are respectively set in the two sets of storage slots 71, and the mounting base 3 has snap-fit ​​grooves 74 on both sides for the irregular blocks 72 to snap into.

[0027] In this design, the receiving groove 71, the irregular block 72, the elastic element 73, and the receiving groove 74 of the snap-fit ​​mechanism 7 cooperate with each other. One side of the irregular block 72 is arc-shaped. When the snap-fit ​​seat 5 is inserted into the mounting groove 4, the irregular block 72 is squeezed by the inner wall of the mounting seat 3, which will compress the elastic element 73 and retract it into the receiving groove 71. When the snap-fit ​​seat 5 is fully pushed into the mounting groove 4, the irregular block 72 corresponds to the snap-fit ​​groove 74 on both sides of the mounting seat 3. The reset force of the elastic element 73 pushes the irregular block 72 out and snaps it into the snap-fit ​​groove 74. With the two sets of irregular blocks 72 arranged symmetrically, the snap-fit ​​seat 5 and the mounting seat 3 can be quickly and stably connected. This structure can complete the installation of the clamping seat 6 without additional tools, which simplifies the installation operation and ensures the stability of the clamping seat 6 after installation, avoiding the impact of loose connection on the fixing effect during the testing process.

[0028] The snap-fit ​​mechanism 7 also includes multiple sets of limiting blocks 75 and multiple sets of limiting grooves 76; the top and bottom of the two sets of irregular blocks 72 are respectively fixedly installed with limiting blocks 75, and the snap-fit ​​base 5 has multiple sets of limiting grooves 76 for the limiting blocks 75 to slide inside.

[0029] Specifically, the limiting block 75 and limiting groove 76 added to the snap-fit ​​mechanism 7 can guide and restrict the sliding direction of the irregular block 72, prevent the irregular block 72 from deviating or getting stuck when sliding in the storage groove 71, ensure that the irregular block 72 can accurately dock with the snap-fit ​​groove 74, and improve the stability and reliability of the snap-fit ​​mechanism 7.

[0030] The elastic element 73 includes two sets of first return springs 731, two sets of fixing rods 732, and two sets of sliding grooves 733. The two sets of fixing rods 732 are fixedly installed inside the receiving groove 71. Two sets of sliding grooves 733 are provided on one side of the irregular block 72 for the fixing rods 732 to slide through. The two sets of first return springs 731 are respectively sleeved on the outside of the two sets of fixing rods 732, and one end of each set of first return springs 731 is installed inside the sliding groove 733, and the other end is pressed against one side of the irregular block 72.

[0031] In this embodiment, the first return spring 731, the fixed rod 732, and the sliding groove 733 of the elastic element 73 cooperate with each other. The fixed rod 732 provides stable support for the first return spring 731, and the sliding groove 733 guides the irregular block 72 to slide along the fixed rod 732, so that the elastic force of the first return spring 731 can act stably on the irregular block 72, ensuring that the irregular block 72 pops out with uniform force and is firmly locked in when it is locked. Moreover, the elastic element 73 has a stable structure and is not easy to deform or fail after long-term use, thus extending the service life of the locking mechanism 7.

[0032] The disassembly mechanism 8 includes two sets of guide rods 81, a movable plate 82, a pressure plate 83, two sets of second return springs 84, and a limiting plate 85. One end of each set of guide rods 81 is fixedly installed on one side of the mounting base 3, and the two sets of limiting plates 85 are respectively fixedly installed on the other end of each set of guide rods 81. The movable plate 82 is slidably disposed on the outside of the two sets of guide rods 81, and the pressure plate 83 is fixedly installed on the side of the movable plate 82 near the irregular block 72. The two sets of second return springs 84 are respectively sleeved on the outside of the two sets of guide rods 81, and one end of each set of second return springs 84 is installed on one side of the mounting base 3, and the other end is pressed against one side of the movable plate 82.

[0033] In this disassembly mechanism 8, the guide rod 81, moving plate 82, pressure plate 83, second return spring 84, and limiting plate 85 cooperate with each other. By simultaneously pushing the moving plate 82 inward, the pressure plate 83 can be driven to squeeze the irregular block 72, causing the irregular block 72 to retract into the storage groove 71, thereby quickly releasing the snap-fit ​​between the snap-fit ​​seat 5 and the mounting seat 3. After the moving plate 82 is released, the second return spring 84 can drive the moving plate 82 to automatically return to its original position. This structure can complete the disassembly of the clamping seat 6 without complicated operations, simplifying the disassembly process and effectively improving the efficiency of replacing the clamping seat 6.

[0034] It also includes an adjustment mechanism 9 for adjusting the spacing between the two sets of support seats 2, and the adjustment mechanism 9 is located on the top of the base 1.

[0035] Specifically, the adjustment mechanism 9 can adjust the distance between the two sets of support seats 2, so that the tooling can flexibly adjust the distance between the clamping seats 6 according to the size of the composite material structural parts to be tested, thereby expanding the tooling's adaptability to structural parts of different sizes, avoiding the problem of unstable clamping due to differences in structural parts size, and improving the practicality of the tooling.

[0036] The adjusting mechanism 9 includes a groove 91, a motor 92, a bidirectional threaded rod 93, and two sets of moving blocks 94. The top of the base 1 has a groove 91. The motor 92 is fixedly installed on one side of the base 1, and the output end of the motor 92 is fixedly connected to one end of the bidirectional threaded rod 93 through a coupling. The bidirectional threaded rod 93 is rotatably installed in the groove. The two sets of moving blocks 94 are threaded to the outside of the bidirectional threaded rod 93, and the tops of the two sets of moving blocks 94 are fixedly connected to the bottoms of the two sets of support seats 2 respectively.

[0037] In the adjustment mechanism 9, the groove, motor 92, bidirectional threaded rod 93 and moving block 94 cooperate with each other. The motor 92 drives the bidirectional threaded rod 93 to rotate, which can drive the moving block 94 to move towards or relative to each other, realizing the automatic adjustment of the spacing of the support seat 2 without manual adjustment, thus improving the adjustment efficiency. At the same time, the bidirectional threaded rod 93 has a smooth transmission and can accurately control the spacing adjustment range, ensuring the clamping accuracy of the clamping seat 6 on the structural components.

[0038] The adjustment mechanism 9 also includes multiple sets of sliders 95 and two sets of slide grooves 96; sliders 95 are fixedly installed on both sides of the two sets of moving blocks 94, and two sets of slide grooves 96 are provided inside the base 1 for the sliders 95 to slide.

[0039] Among them, multiple sets of sliders 95 slide in two sets of sliding grooves 96 respectively, which can guide and restrict the sliding direction of the moving block 94, prevent the moving block 94 from deviating or shaking during the adjustment process, and thus ensure that the support seat 2, mounting seat 3 and clamping seat 6 can maintain stable movement when the spacing is adjusted, and ensure that the clamping seat 6 clamps the structural component accurately.

[0040] Working principle: When using this utility model, firstly, according to the shape of the composite material structural component to be tested, select two sets of suitable clamping seats 6. Align the snap-fit ​​seat 5 on one side of the selected clamping seat 6 with the mounting groove 4 of the mounting base 3 and insert it. During the insertion process, the irregular block 72 in the storage groove 71 on both sides of the snap-fit ​​seat 5 is squeezed by the inner wall of the mounting base 3, compressing the elastic element 73 (the first return spring 731 retracts along the fixing rod 732, and the limiting block 75 slides along the limiting groove 76) and retracting into the storage groove 71. When the snap-fit ​​seat 5 is fully pushed into the mounting groove 4, the irregular block 72 corresponds to the snap-fit ​​groove 74 on both sides of the mounting base 3. The elastic force of the first return spring 731 pushes the irregular block 72 out and snaps into the snap-fit ​​groove 74, realizing the quick fixation of the snap-fit ​​seat 5 and the mounting base 3, and completing the installation of the clamping seat 6.

[0041] After the clamping seat 6 is installed, the motor 92 is started. The output end of the motor 92 drives the bidirectional threaded rod 93 to rotate in the groove of the base 1. Due to the threaded connection between the two sets of moving blocks 94 and the bidirectional threaded rod 93, they move towards or away from each other along the bidirectional threaded rod 93. The slider 95 at the bottom of the moving block 94 slides along the slide groove 96 to improve stability, thereby driving the top support seat 2, mounting seat 3 and clamping seat 6 to move synchronously, realizing the adjustment of the distance between the two sets of clamping seats 6, so that the two sets of clamping seats 6 can stably clamp the composite material structural parts, providing a fixed foundation for subsequent non-destructive testing.

[0042] If a different shaped clamping seat 6 needs to be replaced, simultaneously push the two sets of moving plates 82 to slide along the guide rod 81 towards the mounting seat 3. While the moving plate 82 compresses the second return spring 84, it drives the pressure plate 83 to squeeze the irregular block 72, causing the irregular block 72 to overcome the elastic force of the elastic element 73 and retract into the receiving groove 71, releasing the engagement with the snap-fit ​​groove 74. At this time, the snap-fit ​​seat 5 can be pulled out from the mounting groove 4 to complete the disassembly. After releasing the moving plate 82, the elastic force of the second return spring 84 pushes the moving plate 82 to reset. Then, select a suitable clamping seat 6 and install it in the same way as above.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
