Description

Technical Field

[0001] The present invention relates to the technical field, and particularly to a honeycomb sandwich composite embedded part and a positioning method thereof. Background Art

[0002] In the field of composite material manufacturing, honeycomb sandwich structures are widely used in multiple industries such as aerospace, transportation, and architectural decoration due to their light weight, high strength, good heat insulation and sound insulation properties, and excellent fatigue resistance. With the continuous improvement of product performance requirements in modern industry, how to effectively integrate various functional components into composite material structures has become an important research direction. As a key component for connecting internal and external structures, the embedded part must not only ensure the structural integrity but also have sufficient strength and durability to adapt to the stress distribution under different working conditions. Although traditional metal embedded parts can meet certain mechanical property requirements, they often face problems of interface compatibility and thermal expansion coefficient matching when combined with non-metallic matrix materials, resulting in defects such as debonding or cracking after long-term use.

[0003] Most of the existing honeycomb sandwich composite embedded parts adopt a direct embedding installation method, that is, metal or other material embedded parts are pre-placed before the composite material is formed, and then integrated molding is achieved through resin infusion or hot pressing and curing processes. However, this traditional method has many deficiencies: on the one hand, due to the fixed shape of the embedded part, it is difficult to accurately control its position accuracy in the plate, especially when applied to complex curved surfaces or shaped components, there are great limitations; on the other hand, there is a lack of an effective transition layer design between the embedded part and the surrounding matrix material, which is likely to cause local stress concentration, affecting the safety and reliability of the overall structure. In addition, for some special application scenarios (such as high-temperature environments), the selection of traditional embedded part materials is also restricted and cannot well meet the usage requirements under specific conditions. In contrast, the present invention proposes a new type of honeycomb sandwich composite embedded part and a positioning method thereof, which not only solves the above problems but also shows significant advantages in improving the installation accuracy of the embedded part, enhancing the interfacial bonding force, and broadening the scope of application.

[0004] Specifically, when the prior art deals with the bonding between honeycomb sandwich composites and embedded parts, the following challenges are usually encountered: First, the fixing method of the embedded parts is not flexible enough to adjust their specific positions in the plate according to actual needs; second, the connection strength between the embedded parts and the composites is insufficient, especially prone to loosening or even falling off under large loads; finally, impurities or moisture are easily introduced during the construction process, thus affecting the quality of the final product. In view of these problems, the present invention provides a complete solution, aiming to improve the performance of the entire system by improving the design and installation process of the embedded parts. The present invention belongs to the technical field of composite material processing, and particularly relates to an embedded part for enhancing the internal connection stability of honeycomb sandwich composites, its positioning method and processing device. By introducing special structural designs and supporting tools, a tight fit between the embedded part and the composite material plate is achieved, ensuring a good contact without gaps between the two, while simplifying the operation process and improving work efficiency. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a honeycomb sandwich composite material embedded part, including: an embedded part body, the embedded part body includes a barrel part, upper and lower circular ring parts are provided on the barrel part, and first threaded holes are opened inside the barrel part and the circular ring parts.

[0006] A foaming glue layer is provided on the outer side of the embedded part body, and the embedded part body is arranged inside the honeycomb sandwich composite material plate.

[0007] The present invention also provides a positioning method for a honeycomb sandwich composite material embedded part, including the honeycomb sandwich composite material embedded part described above, and comprising the following steps: S1. Prepare the first positioning tooling and clean it thoroughly, confirm that there are no obvious stains or dust on the surface, then evenly apply a release agent on the first positioning tooling, and wait for 15 minutes until the release agent dries, and then prepare the positioning work of the honeycomb embedded part; S2. After the honeycomb sandwich composite material plate is taken out, cut it first according to the product size, then use a vacuum cleaner to suck out the impurities in the honeycomb, and clean it once with anhydrous ethanol, and put it into an oven at 75 °C and keep it warm for 2 hours to ensure that the water vapor in the honeycomb sandwich composite material plate is removed; S3. Then use a cutting device above the first positioning tooling to process an opening for placing the embedded part body on the honeycomb sandwich composite material plate; S4. Wrap the middle area of the embedded part body with foaming glue, then place the embedded part body wrapped with foaming glue into the opening of the corresponding honeycomb sandwich composite board. Transfer the honeycomb sandwich composite board with the embedded part body above the second positioning tooling, insert the upper positioning plate and the lower positioning plate, use the positioning rotation device to fix the position of the pin screw and the embedded part body, and finally fill the honeycomb grid around the embedded part body with foaming glue; S5. Insert an aluminum spacer block between the upper positioning plate and the lower positioning plate and connect them with the second screw; S6. After the foaming glue filling is completed, make a vacuum bag and transfer it to the oven for foaming of the foaming glue; S7. Remove the surface auxiliary materials of the pre-shaped honeycomb sandwich composite board, check whether there is insufficient foaming of the foaming glue around the embedded part body. If there is insufficient foaming, fill the foaming-deficient area with foaming glue. If there is over-foaming or overflow of the foaming glue, use a blade to remove the excess foaming glue to ensure the surface of the honeycomb sandwich composite board is flat and there is no obvious gap between the embedded part body and the honeycomb sandwich composite board.

[0008] The present invention also provides a processing device applied to the positioning method of the honeycomb sandwich composite embedded part. The cutting device includes a first top plate. A first cylinder is fixedly connected to the upper part of the first top plate. The lower end of the piston rod of the first cylinder is fixedly connected to a first lifting plate. A plurality of first motors are installed on the first lifting plate. The lower end of the output shaft of the first motor is fixedly connected to a cup-shaped cutting head. A sawtooth structure is provided below the cup-shaped cutting head. A connecting block for connecting a suspension rod is provided on the upper part of the first top plate.

[0009] The first positioning tooling includes two first L-shaped plates. Legs are welded to the lower parts of the first L-shaped plates. A second lifting plate is slidably connected to the legs. Conveyor rollers are provided on the upper part of the second lifting plate. The conveyor rollers are driven by a driving motor and a belt. A second cylinder is connected to the lower part of the second lifting plate. The piston rod of the second cylinder can drive the second lifting plate to rise so that the conveyor rollers contact the bottom of the first positioning tooling and convey the honeycomb sandwich composite board placed on the upper part of the first positioning tooling.

[0010] A dust collection box is provided between the first positioning tooling and the conveyor rollers. A pull rod is welded to the rear part of the dust collection box. The pull rod is slidably connected to a floor-standing vacuum cleaner. A third cylinder is connected to the rear part of the pull rod. The third cylinder can pull the pull rod and the dust collection box to move back and forth. A hose is connected between the dust collection box and the floor-standing vacuum cleaner. The vacuum cleaner in the floor-standing vacuum cleaner can extract the dust in the dust collection box through the hose.

[0011] The positioning and rotating device includes two annular support plates. Rack teeth are provided on the annular support plates. A number of support gears meshing with the annular support plates are connected to the annular support plates. The support gears are rotatably connected to support legs. A driving gear is connected to the annular support plate. The driving gear is driven by a driving motor. When the driving gear rotates, the annular support plate is driven to rotate. The annular support plate is fixedly connected to the second positioning tooling through a connecting rod. The second positioning tooling includes two semi-frame plates.

[0012] A number of vacuum suction cups are fixedly connected to the side of the semi-frame plate. A number of first micro-cylinders are fixedly connected to the lower part of the semi-frame plate. The telescopic rod of the first micro-cylinder penetrates through the semi-frame plate and can jack up the honeycomb sandwich composite plate. The vacuum suction cups can adsorb the honeycomb sandwich composite plate to keep it suspended.

[0013] A second top plate is provided on the upper part of the second positioning tooling. The lower part of the second top plate is connected to a third top plate through a connecting rod. A second micro-cylinder and a third micro-cylinder are connected to the third top plate. The lower end of the piston rod of the second micro-cylinder is connected to an electric screwdriver. The lower end of the piston rod of the third micro-cylinder is connected to a lubricating oil water pump. The lower part of the lubricating oil water pump is connected to a fuel injection pipe. A strip hole is provided on the third top plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By precisely controlling the rotation angle of the annular support plate, it can ensure that the position of the honeycomb sandwich composite plate after turning over is accurate and error-free, which is crucial for the precise positioning of subsequent embedded parts. Compared with the manual turning method, this automated system significantly reduces human error and improves the overall accuracy of the installation of embedded parts.

[0015] 2. Using vacuum suction cups to adsorb the plate and keep it suspended not only avoids damage to the plate that may be caused by traditional fixtures, but also makes the entire turning process more stable and reliable. Especially for thinner or larger-sized plates, this method can effectively prevent the plate from bending or cracking during the turning process.

[0016] 3. Since the honeycomb sandwich composite plate is firmly adsorbed on the semi-frame plate and slightly jacked up by the first micro-cylinder, this provides sufficient space and convenience for inserting the upper and lower positioning plates. The smooth insertion of the positioning plate is a key step to ensure the correct fixation of the embedded part, and this design greatly simplifies the operation process and improves work efficiency.

[0017] 4. By designing the first positioning tooling composed of two first L-shaped plates and integrating components such as the second lifting plate, conveying rollers, and the second cylinder inside it, one-stop automated processing of honeycomb core composite material plates from taking out to positioning is achieved. This design not only simplifies the traditional manual handling process and reduces labor intensity, but also, with the help of the drive motor and belt drive system, can achieve adaptive adjustment for plates of different thicknesses, enhancing the flexibility of the system. Notably, when the second cylinder operates, it can drive the second lifting plate to rise, enabling the conveying rollers to contact the bottom of the positioning tooling, thus smoothly feeding the plates into the designated position. This intelligent conveying mechanism greatly shortens the processing cycle and improves the overall operation efficiency of the production line. At the same time, it also provides a solid foundation for subsequent steps, helping to ensure the quality and accuracy of embedded part installation.

[0018] 5. By setting a dust collection box between the first positioning tooling and the conveying rollers and connecting it to the vacuum cleaner cabinet through a pull rod, the third cylinder, and a hose, an efficient dust collection and suction system is constructed. This system can remove generated debris and dust in real time during cutting and other processing operations, maintaining the cleanliness of the working environment. Specifically, the third cylinder pulls the pull rod to move the dust collection box back and forth, cooperating with the operation of the vacuum cleaner cabinet, which can effectively suck and store the dust scattered in the collection box. This step not only improves the working conditions in the workshop and reduces environmental pollution, but also plays a crucial role in preventing foreign objects from mixing into the product, ensuring the smoothness of the finished product surface and the integrity of the internal structure.

Remove the surface auxiliary materials of the pre-shaped honeycomb sandwich composite material board 37, check whether there is a phenomenon of insufficient foaming of the foaming glue around the embedded part body 35. If there is a phenomenon of insufficient foaming, fill the foaming-deficient area with foaming glue; if there is over-foaming or overflow of the foaming glue, use a blade to remove the excess foaming glue to ensure that the surface of the honeycomb sandwich composite material board 37 is flat and there is no obvious gap between the embedded part body 35 and the honeycomb sandwich composite material board 37.

[0035] The present invention also provides a processing device, which is applied to the positioning method of embedded parts of honeycomb sandwich composite materials.

[0036] The first positioning fixture 10 includes two first L-shaped plates 10, and a support leg 20 is welded at the bottom of the first L-shaped plate 10. A second lifting plate 18 is slidably connected to the support leg 20. A conveying roller 22 is provided at the top of the second lifting plate 18, and the conveying roller 22 is driven by a driving motor and a belt. The bottom of the second lifting plate 18 is connected to a second cylinder 19, and the piston rod of the second cylinder 19 can drive the second lifting plate 18 to rise, so that the conveying roller 22 contacts the bottom of the first positioning fixture 10 and conveys the honeycomb sandwich composite material panel 37 placed on the top of the first positioning fixture 10.

[0037] A dust collecting box 14 is provided between the first positioning tool 10 and the conveying roller 22. A pull rod 13 is welded to the rear of the dust collecting box 14. The pull rod 13 is slidably connected to the vacuum cleaner cabinet 11. The rear of the pull rod 13 is connected to the third cylinder 12. The third cylinder 12 can pull the pull rod 13 and the dust collecting box 14 to move forward and backward. A hose 21 is connected between the dust collecting box 14 and the vacuum cleaner cabinet 11. The vacuum cleaner in the vacuum cleaner cabinet 11 can extract dust from the dust collecting box 14 through the hose 21.

[0038] The positioning and rotating device includes two annular support plates 6, on which racks are provided, and on which a plurality of support gears 8 meshing therewith are connected, and the support gears 8 are rotatably connected to the support legs 7, and on which a driving gear 29 is connected, and the driving gear 29 is driven by a driving motor, and when the driving gear 29 rotates, the annular support plate 6 is driven to rotate, and the annular support plate 6 is fixedly connected to the second positioning fixture 9 via a connecting rod, and the second positioning fixture 9 includes two half-frame plates.

[0039] A number of vacuum suction cups 31 are fixedly connected to the side of the half-frame plate, and a number of first micro cylinders 30 are fixedly connected to the lower part of the half-frame plate. The telescopic rods of the first micro cylinders 30 pass through the half-frame plate and can lift up the honeycomb sandwich composite material plate 37. The vacuum suction cups 31 can absorb the honeycomb sandwich composite material plate 37 to keep it suspended.

[0040] The upper part of the second positioning tooling 9 is provided with a second top plate 2. The lower part of the second top plate 2 is connected with a third top plate 4 through a connecting rod. A second micro-cylinder 24 and a third micro-cylinder 26 are connected to the third top plate 4. The lower end of the piston rod of the second micro-cylinder 24 is connected with an electric screwdriver 25, and the lower end of the piston rod of the third micro-cylinder 26 is connected with a lubricating oil water pump 27. The lower part of the lubricating oil water pump 27 is connected with a fuel injection pipe 28. A strip-shaped hole 23 is provided on the third top plate 4.

[0041] Working principle: When in use, first, the first positioning tooling 10 needs to be prepared. Ensure that its surface is clean without stains or dust, and evenly apply a release agent to prevent material adhesion during subsequent processing. After waiting for the release agent to dry, the positioning preparation work of the honeycomb embedded parts can be started.

[0042] Next, the honeycomb sandwich composite board 37 will be taken out and cut according to the product size. To ensure the cleanliness inside the board, impurities in the honeycomb need to be removed with a vacuum cleaner, and it is washed once with anhydrous ethanol. Then, the processed honeycomb sandwich composite board 37 is placed in an oven and kept warm at 75 °C for 2 hours to ensure that all internal water vapor is removed.

[0043] After completing the above pretreatment steps, the honeycomb sandwich composite board 37 is precisely drilled through the cutting device installed above the first positioning tooling 10. The cutting device consists of a first top plate 1, a first cylinder 15, a first lifting plate 5, several first motors 16 and a cup-shaped cutting head 17 with a serrated structure. Specifically, the first cylinder 15 drives the first lifting plate 5 to move up and down, and the first motor 16 drives the cup-shaped cutting head 17 to rotate to achieve the cutting action. In addition, a connecting block 3 for connecting the suspension rod is provided at the top of the first top plate 1, which is convenient for the overall hoisting of the equipment.

[0044] When a hole for placing the embedded part body 35 is successfully processed on the honeycomb sandwich composite board 37, the next step is to wrap the middle area of the embedded part body 35 with foaming glue and place it into the corresponding hole position. At this time, the entire honeycomb sandwich composite board 37 with the embedded part body 35 is transferred onto the second positioning tooling 9. The second positioning tooling 9 is composed of two semi-frame plates. A plurality of vacuum suction cups 31 are fixed on the side of each semi-frame plate. These vacuum suction cups 31 can adsorb the board to keep it in a suspended state; before that, the first micro-cylinder 30 can slightly lift the board to facilitate the insertion of the upper and lower positioning plates. Then, use the electric screwdriver 25 on the positioning and rotating device to pass the pin screw 32 through the positioning plate and fix it to the embedded part body 35, and fill the honeycomb grid gaps around the embedded part to ensure that the foaming glue is fully filled.

[0045] In order to further strengthen the bonding strength between the embedded part body 35 and the honeycomb sandwich composite material board 37, an aluminum spacer 38 is inserted between the upper positioning plate 34 and the lower positioning plate 33 and fixed by the second screw 39. This measure not only helps to disperse the pressure but also improves the stability of the overall structure.

[0046] After the above assembly is completed, the filling operation of the foaming adhesive is carried out immediately. A vacuum bag is made and the assembly is transferred to an oven to make the foaming adhesive foam and cure at an appropriate temperature. During this period, the foaming process should be closely monitored to ensure that the foaming adhesive is completely filled and there is no overflow. If it is found that the foaming is insufficient, the foaming adhesive should be replenished in time; on the contrary, if there is over-foaming or overflow, the excess part needs to be carefully removed with a blade, and finally ensure that the surface of the honeycomb sandwich composite material board 37 is flat and smooth, and there is no obvious gap between the embedded part body 35 and it.

[0047] The last step is to clean the surface of the pre-shaped honeycomb sandwich composite material board 37. After removing the auxiliary materials, carefully check whether there is a problem of insufficient foaming of the foaming adhesive around the embedded part body 35 and take corresponding measures to correct it according to the actual situation. In this way, the manufacturing process of the entire honeycomb sandwich composite material embedded part is completed, providing a high-quality basic component for subsequent applications.

[0048] During the whole process, the annular support plate 6 plays a key role. It cooperates with the driving gear 29 to drive the whole system to rotate around the central axis when the driving motor starts, so as to realize the rotation and turning operation of the honeycomb sandwich composite material board 37 placed on it under precise control. Thus, the release agent can be sprayed, which is convenient for inserting the positioning plates step by step and installing the screws, and is convenient for observing and screwing when rotating to the upper part. This design not only improves the installation accuracy of the embedded part but also simplifies the insertion process of the upper and lower positioning plates, promoting the automation and continuity of the production process.

[0049] In summary, this set of honeycomb sandwich composite material embedded parts and its positioning method ensure the high-quality production and efficient assembly of the product through a series of carefully designed steps and technical means, are applicable to the field of modern composite material manufacturing, and have important application value and development potential.
