Description

Technical Field

[0001] This utility model specifically relates to a pressing device for the production and processing of honeycomb panels, belonging to the field of honeycomb panel production and processing technology. Background Technology

[0002] In the aerospace manufacturing industry, aviation aluminum honeycomb panels, as a core representative of lightweight structural materials, are widely used in critical components such as aircraft fuselage skin, wing structures, and engine nacelles. This material is composed of high-strength aluminum alloy panels and a honeycomb core. With its unique "sandwich" structure, it possesses excellent specific strength and specific stiffness characteristics, effectively improving structural load-bearing capacity and fatigue resistance while reducing the overall weight of the aircraft. This is crucial for reducing aircraft energy consumption and improving flight performance.

[0003] In modern industrial manufacturing, the demand for lamination processing of honeycomb panels with special shapes is increasing, especially for honeycomb panels with irregular shapes such as wavy undulations and textured surfaces, which are widely used in aerospace, automotive manufacturing, and high-end equipment. However, traditional lamination devices generally use a fixed rigid structure, whose lamination surface cannot effectively fit the complex surface contours of special-shaped panels. During the lamination process, this rigid structure leads to uneven stress on the panel: raised areas bear excessive pressure, which can easily cause surface damage, material deformation, or even cracking; while recessed or low-lying areas suffer from insufficient pressure, resulting in weak lamination, local gaps, and other problems, seriously affecting the structural strength and appearance quality of the product. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a pressing device for the production and processing of honeycomb panels. Through the reset spring, the sliding of the inner rod, and the pressure adjustment of the vent hole, the pressing block can float independently according to the surface undulations of the honeycomb panel. At the same time, negative pressure adsorption ensures tight adhesion, avoids uneven force caused by inconsistent surface morphology, prevents local incomplete pressing or surface damage, and significantly improves the internal structural strength and appearance quality of the honeycomb panel.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a pressing device for honeycomb panel production and processing, comprising a box body, wherein a protective door is rotatably connected to the surface of the box body via a connecting hinge.

[0006] A cylinder is fixedly installed on the inner top surface of the housing. An upper pressure plate is fixedly connected to the telescopic end of the cylinder. Multiple flexible connectors are fixedly connected to the bottom surface of the upper pressure plate in a rectangular array.

A lower pressure plate is fixedly connected to the top end of the support columns.

[0007] Preferably, in order to accurately define the position of the component to be pressed on the lower pressing plate and ensure that it does not move arbitrarily during the pressing process, thereby ensuring the accuracy and consistency of the pressing, L-shaped limiting blocks are fixedly connected to the four corners of the surface of the lower pressing plate.

[0008] Preferably, in order to ensure that the upper pressing plate can apply pressure vertically to the honeycomb panel and avoid tilting or displacement, thereby ensuring that the pressure is evenly distributed on the honeycomb panel during the pressing process and reducing quality problems caused by uneven pressure, positioning posts are symmetrically fixedly connected to both sides of the lower pressing plate, and positioning blocks are symmetrically fixedly connected to both sides of the upper pressing plate. The positioning posts are inserted into sliding holes opened on the surface of the positioning blocks, and the positioning posts and positioning blocks are slidably connected.

[0009] Preferably, in order to efficiently recover the cleaning fluid, prevent the cleaning fluid from flowing and dripping everywhere, prevent it from polluting the working environment or seeping into the equipment, and ensure the cleanliness of the working area and the normal operation of the equipment, the housing is provided with an installation cavity located directly below the lower pressing plate. A recovery drawer is slidably connected in the installation cavity, and guide blocks are symmetrically fixedly connected above the installation cavity. The surface of the guide blocks is provided with an inclined surface.

[0010] Preferably, in order to effectively control the horizontal and vertical position of the control panel on the horizontal plane, ensure that the panel is in the center area of ​​the upper and lower pressing plates or the preset pressing position, avoid problems such as pressing misalignment and insufficient edge pressing caused by installation deviation, and ensure pressing accuracy and quality, a limit ruler is fixedly connected to two adjacent sides of the upper pressing plate, and a rectangular hole for the limit ruler to be inserted is opened on the surface of the lower pressing plate, and the limit ruler can slide in the rectangular hole.

[0011] Preferably, in order to independently adjust the position according to the surface morphology of the honeycomb panel, the pressure block at the protruding part of the surface is squeezed and slides upward to compress the return spring, while the pressure block at the concave part moves downward under the action of the return spring, thereby closely fitting the surface of the honeycomb panel, realizing adaptive pressing, ensuring that the entire surface of the honeycomb panel is subjected to uniform force, and avoiding local incompatibility or excessive pressure damage. The flexible connector includes a hollow outer rod, a return spring, an inner rod, a pressure block, and a flexible rubber pad. The hollow outer rod is fixedly connected to the upper pressing plate, and the inner rod is slidably connected in the inner cavity of the hollow outer rod. A return spring is fixedly connected between the inner rod and the hollow outer rod. The bottom end of the return spring extends to the lower side of the hollow outer rod and is fixedly connected to the pressure block located on the lower side of the hollow outer rod. A flexible rubber pad is fixedly connected to the bottom surface of the pressure block. Ventilation holes are opened at the center positions of the hollow outer rod, the inner rod, and the pressure block. The ventilation holes and air outlets opened on the surface of the hollow outer rod are connected.

[0012] Preferably, in order to limit the movement trajectory of the inner rod, a limiting slider is symmetrically fixedly connected to the surface of the inner rod, and a limiting groove is symmetrically opened on the inner wall of the hollow outer rod, with the limiting slider slidably connected in the limiting groove.

[0013] Preferably, in order to ensure the airtightness of the vent when connected to an external air source, prevent gas leakage, and ensure the stable and reliable function of adjusting the initial pressure of the pressure block through the vent, a sealing ring is fixedly connected to the bottom end of the hollow outer rod, and the inner rod slides through the sealing ring.

[0014] The beneficial effects of this utility model are:

[0015] 1. This device, through an innovative design that integrates flexible connectors and a negative pressure adsorption system, can precisely adapt to the complex surface morphology of aerospace aluminum honeycomb panels, effectively overcoming the problem of uneven force distribution in traditional pressing processes. During the pressing operation, multiple flexible connectors arranged in a rectangular array at the bottom of the upper pressing plate work synchronously: the raised areas on the honeycomb panel surface contact the pressing blocks first, forcing the blocks to slide upwards, while the inner rod compresses the return spring within the hollow outer rod, creating elastic yielding; meanwhile, the pressing blocks corresponding to the recessed areas extend downwards under the elastic restoring force of the return springs, actively filling the gaps. Each pressing block floats independently based on the differences in the honeycomb panel surface contour, ensuring that each contact point is tightly fitted;

[0016] During this process, the vent holes in the hollow outer rod, inner rod, and center of the pressure block, together with the vent holes in the upper pressing plate, the corrugated expansion tube, and the air supply pipe, constitute a complete air circuit system. After the negative pressure pump is started, air is drawn from inside the flexible connector through the air circuit, causing the flexible rubber pad on the bottom of the pressure block to form a negative pressure adsorption effect with the surface of the honeycomb panel, further enhancing the tightness of the fit. This dual mechanism of "mechanical self-adaptation + negative pressure adsorption" not only ensures that every undulation on the surface of the honeycomb panel receives uniform and sufficient pressure, completely avoiding the structural loosening problem caused by localized insufficient pressing, but also prevents scratches, indentations, and other damage to the surface of the aerospace aluminum material caused by pressure concentration, effectively improving the internal structural strength and surface integrity of the honeycomb panel, and significantly increasing the finished product qualification rate.

[0017] 2. It can achieve efficient and precise positioning. The L-shaped limiting blocks at the four corners of the lower pressing plate, the sliding cooperation between the positioning posts and the positioning blocks, and the guiding structure of the upper pressing plate limiting ruler and rectangular holes form a multi-dimensional positioning system. It can quickly and accurately fix the position of the honeycomb panel, ensuring that it is in the center area of ​​the pressing, avoiding pressing misalignment and insufficient edge pressing, while simplifying the manual operation process and reducing installation errors.

[0018] 3. The installation cavity, guide block and recovery drawer constitute the cleaning fluid recovery system. The inclined surface guides the cleaning fluid into the drawer, avoiding liquid pollution of the equipment and working environment. The drawer can be disassembled for cleaning, reducing maintenance difficulty, ensuring long-term stable operation of the equipment, and meeting the environmental protection requirements of industrial production.

[0028] 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.

[0029] Please see Figures 1-8 As shown, a pressing device for honeycomb panel production and processing includes a housing 1, and a protective door 2 is rotatably connected to the surface of the housing 1 via a connecting hinge.

[0030] A cylinder 3 is fixedly installed on the inner top surface of the housing 1. The telescopic end of the cylinder 3 is fixedly connected to an upper pressure plate 4. The bottom surface of the upper pressure plate 4 is fixedly connected to multiple flexible connectors 19 in a rectangular array. The bottom surface of the upper pressure plate 4 is opened with multiple air outlets 18 in a circular array. Each air outlet 18 is connected to a flexible connector 19. A corrugated telescopic tube 13 is fixedly connected to the surface of the upper pressure plate 4. An air supply pipe 12 is fixedly connected to the top of the corrugated telescopic tube 13. A negative pressure pump 10 is fixedly installed on the side surface of the housing 1. The air inlet of the negative pressure pump 10 is connected to the air supply pipe 12. An air outlet pipe 11 is fixedly connected to the air outlet of the negative pressure pump 10. Support columns 5 are fixedly connected to the inner bottom surface of the housing 1 near the four corners. The top of the support column 5 is fixedly connected to a lower pressure plate 6.

[0031] Specifically, L-shaped limiting blocks 7 are fixedly connected to the four corners of the surface of the lower pressure plate 6.

[0032] When placing the aerospace-grade aluminum honeycomb panel, the operator positions the panel along the four L-shaped limiting blocks 7 at the four corners of the lower pressing plate 6. The two vertical surfaces of the L-shaped limiting blocks 7 form a right-angle limiting structure. By aligning the edge of the honeycomb panel with the vertical surface of the L-shaped limiting blocks 7, the position of the honeycomb panel on the lower pressing plate 6 can be quickly and accurately determined. During the subsequent downward pressing of the upper pressing plate 4 by the cylinder 3, the L-shaped limiting blocks 7, with their fixed structure, effectively prevent lateral movement of the honeycomb panel, ensuring its stable position throughout the pressing process. This avoids quality problems such as misalignment and incomplete edge pressing caused by displacement, significantly improving pressing accuracy and product qualification rate.

[0033] Specifically, positioning posts 8 are symmetrically fixedly connected to both sides of the lower pressing plate 6, and positioning blocks 9 are symmetrically fixedly connected to both sides of the upper pressing plate 4. The positioning posts 8 are inserted into sliding holes on the surface of the positioning blocks 9, and the positioning posts 8 and the positioning blocks 9 are slidably connected.

[0034] When cylinder 3 drives the upper pressing plate 4 to move downwards for pressing, the positioning blocks 9 on both sides of the upper pressing plate 4 slide downwards along the positioning posts 8 on both sides of the lower pressing plate 6. The positioning posts 8 and the sliding holes on the surface of the positioning blocks 9 form a precise sliding fit. Throughout the pressing process, the positioning posts 8 always slide within the sliding holes, providing precise guidance for the downward movement of the upper pressing plate 4. The upper pressing plate 4 can only move vertically along the axial direction of the positioning posts 8, avoiding tilting or offset caused by lateral forces or other factors during the pressing process. This ensures that the upper pressing plate 4 can apply pressure to the honeycomb panel vertically and stably until the pressing action is completed. After the pressing is completed, cylinder 3 drives the upper pressing plate 4 to move upwards and reset. The positioning posts 8 and the positioning blocks 9 still maintain a sliding fit, ensuring that the upper pressing plate 4 can accurately return to its initial position.

[0035] Specifically, the housing 1 has an installation cavity 15 located directly below the lower pressure plate 6. A recycling drawer 16 is slidably connected inside the installation cavity 15. A guide block 14 is symmetrically fixed above the installation cavity 15, and the surface of the guide block 14 is provided with an inclined surface.

[0036] After the lamination process of the aviation aluminum honeycomb panel is completed, if it is necessary to clean the residual colloids and other impurities on the surface of the lower lamination plate 6, the cleaning fluid is sprayed or rinsed onto the surface of the lower lamination plate 6. Because the surface of the guide block 14 has an inclined surface, the cleaning fluid flows naturally along the inclined surface under gravity and is guided to the mounting cavity 15 located directly below the lower lamination plate 6 inside the housing 1. The recycling drawer 16 inside the mounting cavity 15 is slidably connected to the mounting cavity 15, and the cleaning fluid ultimately flows into the recycling drawer 16 for collection. After the recycling drawer 16 is full of cleaning fluid, the operator can directly pull it out of the mounting cavity 15 for centralized processing. After cleaning, the recycling drawer 16 is slid back into the mounting cavity 15 for the next cleaning fluid recycling operation. Utilizing the inclined surface of the guide block 14 and the principle of gravity, automatic guidance and collection of the cleaning fluid can be achieved without an additional power device, forming a low-cost, high-efficiency waste liquid recycling system. Compared to manual cleaning or non-recycling structures, this method greatly reduces manpower input, improves equipment maintenance efficiency, ensures the continuity of the production process, solves the problem of cleaning fluid flowing and dripping everywhere, avoids slippery and contaminated work areas, reduces safety hazards, and keeps the production workshop clean.

[0037] Specifically, the upper pressing plate 4 has two adjacent sides fixedly connected with limit rulers 17, and the surface of the lower pressing plate 6 has a rectangular hole 20 for the limit ruler 17 to be inserted, and the limit ruler 17 can slide within the rectangular hole 20.

[0038] When placing the aviation aluminum honeycomb panel to be pressed, the operator positions the panel below the upper pressing plate 4, using the locating rulers 17 fixed on both sides of the upper pressing plate 4 as positioning references. The locating rulers 17 are aligned with the sides of the honeycomb panel, forming a horizontal limiting boundary. The operator can visually align the two sides of the honeycomb panel with the locating rulers 17 to quickly determine the accurate position of the honeycomb panel within the projection area of ​​the upper pressing plate 4. After positioning, the cylinder 3 drives the upper pressing plate 4 downwards. At this time, the locating rulers 17 assist in guiding the honeycomb panel smoothly into the L-shaped limiting block 7 of the lower pressing plate 6, achieving precise positioning of the honeycomb panel from top to bottom. Throughout the process, the locating rulers 17, through clear boundary constraints, significantly reduce the adjustment time during honeycomb panel installation, ensuring that it is quickly and accurately positioned in the preset pressing position.

[0039] Specifically, the flexible connector 19 includes a hollow outer rod 1901, a return spring 1902, an inner rod 1904, a pressure block 1907, and a flexible rubber pad 1908. The hollow outer rod 1901 is fixedly connected to the upper pressing plate 4. The inner rod 1904 is slidably connected in the inner cavity of the hollow outer rod 1901. The return spring 1902 is fixedly connected between the inner rod 1904 and the hollow outer rod 1901. The bottom end of the return spring 1902 extends to the lower side of the hollow outer rod 1901 and is fixedly connected to the pressure block 1907 located on the lower side of the hollow outer rod 1901. The flexible rubber pad 1908 is fixedly connected to the bottom surface of the pressure block 1907. Ventilation holes 1903 are opened at the center positions of the hollow outer rod 1901, the inner rod 1904, and the pressure block 1907. The ventilation holes 1903 opened on the surface of the hollow outer rod 1901 are connected to the air outlet 18.

[0040] In use, a honeycomb panel is placed under the upper pressing plate 4, and the negative pressure pump 10 is started. The negative pressure pump 10 is connected to the air outlet 18 on the surface of the upper pressing plate 4 through the air supply pipe 12 and the corrugated expansion pipe 13, which in turn connects to the air vent 1903 in the flexible connector 19. At this time, a negative pressure adsorption force is formed between the flexible rubber pad 1908 on the bottom surface of the pressing block 1907 and the surface of the honeycomb panel, firmly adsorbing the honeycomb panel onto the bottom surface of the upper pressing plate 4. Then, the cylinder 3 is started, and the telescopic end of the cylinder 3 drives the upper pressing plate 4 to move downward. During this process, the positioning blocks 9 on both sides of the upper pressing plate 4 slide along the positioning posts 8 on both sides of the lower pressing plate 6 to ensure that the upper pressing plate 4 moves vertically downward; at the same time, the limiting ruler 17 on the side of the upper pressing plate 4 is also inserted into the rectangular hole 20 of the lower pressing plate 6 to further limit the horizontal displacement of the upper pressing plate 4 and ensure the motion accuracy. As the pressure plate 6 approaches, the flexible connector 19 plays a crucial role: if there are unevennesses on the surface of the honeycomb panel, the inner rod 1904 slides within the hollow outer rod 1901, working in conjunction with the return spring 1902 to achieve adaptive adjustment, ensuring that the pressure block 1907 fits tightly against the honeycomb panel surface. Ultimately, the upper and lower honeycomb panels achieve precise and uniform pressing under the combined action of cylinder pressure, the adaptive adjustment of the flexible connector, and negative pressure adsorption. After pressing is completed, the cylinder 3 drives the upper pressure plate 4 to rise and reset, the negative pressure pump 10 stops working, the negative pressure adsorption is released, and the pressed honeycomb panel can be removed. The flexible connector 19 can compensate in real time for potential surface unevenness and thickness differences between the upper and lower honeycomb panels. The combination of the inner rod 1904 and the return spring 1902 allows the pressure block 1907 to adjust independently according to the surface morphology of the honeycomb panel, ensuring that all contact areas between the two honeycomb panels fit tightly and are subjected to uniform force, preventing localized incomplete pressing or excessive pressure damage, and improving the overall structural strength and stability of the honeycomb panel assembly.

[0041] Specifically, the inner rod 1904 has a symmetrical fixed connection of a limiting slider 1906 on its surface, and the inner wall of the hollow outer rod 1901 has symmetrically opened limiting grooves 1905, in which the limiting slider 1906 is slidably connected.

[0042] Specifically, a sealing ring 1909 is fixedly connected to the bottom end of the hollow outer rod 1901, and the inner rod 1904 slides through the sealing ring 1909.

[0043] During the operation of the flexible connector 19, the sealing ring 1909 tightly fits against the inner rod 1904, forming a sealed structure. When the negative pressure pump 10 starts to extract air, the sealing ring 1909 prevents external gas from entering the vent 1903 through the gap between the hollow outer rod 1901 and the inner rod 1904, ensuring the airtightness of the negative pressure adsorption system. When the inner rod 1904 slides up and down under the action of the return spring 1902, the sealing ring 1909 relies on its own elastic deformation to always maintain close contact with the inner rod 1904, which neither affects the flexible sliding of the inner rod 1904 nor fails to maintain the sealing state, ensuring the stable operation of the negative pressure adsorption and adaptive pressing functions.

[0044] Working principle: When using this pressing device, the operator first places a honeycomb panel on the surface of the lower pressing plate 6 and uses the L-shaped limiting blocks 7 at the four corners of the lower pressing plate 6 for positioning. The right-angle structure of the L-shaped limiting blocks 7 provides a clear horizontal positioning reference for the honeycomb panel. The operator only needs to align the edge of the honeycomb panel with the vertical surface of the L-shaped limiting block 7 to quickly determine its position on the lower pressing plate 6. At the same time, the L-shaped limiting blocks 7 can effectively prevent the lateral movement of the honeycomb panel during the subsequent pressing process.

[0045] Subsequently, another honeycomb panel is placed below the upper pressing plate 4, and the negative pressure pump 10 is started. The negative pressure pump 10 is connected to the air outlet 18 on the surface of the upper pressing plate 4 through the air supply pipe 12 and the corrugated expansion pipe 13, thereby connecting the air vent 1903 in the flexible connector 19. At this time, a negative pressure adsorption force is formed between the flexible rubber pad 1908 on the bottom surface of the pressure block 1907 of the flexible connector 19 and the surface of the honeycomb panel, which firmly adsorbs the honeycomb panel onto the bottom surface of the upper pressing plate 4, thus completing the fixation of the upper honeycomb panel.

[0046] Then, cylinder 3 is activated. After cylinder 3 is activated, its telescopic end drives the upper pressing plate 4 to move downward. During this process, the positioning pins 8 on both sides of the lower pressing plate 6 and the positioning blocks 9 on both sides of the upper pressing plate 4 play a guiding role. The positioning pins 8 are inserted into the sliding holes on the surface of the positioning blocks 9, forming a precise sliding fit, which strictly limits the upper pressing plate 4 to moving vertically along the axial direction of the positioning pins 8, avoiding tilting or offset due to lateral forces. At the same time, the limit rulers 17 on the adjacent sides of the upper pressing plate 4 are inserted into the corresponding rectangular holes 20 on the surface of the lower pressing plate 6. The sliding fit between the limit rulers 17 and the rectangular holes 20 further enhances the guiding accuracy of the upper pressing plate 4 when it moves downward, ensuring that the upper and lower pressing plates are accurately aligned in the vertical direction, laying the foundation for subsequent pressing operations.

[0047] As the upper pressing plate 4 pulls the adsorbed honeycomb panel closer to the honeycomb panel on the lower pressing plate 6, the flexible connectors 19, arranged in a rectangular array on the bottom surface of the upper pressing plate 4, begin to play a crucial role. Due to the irregular shapes of the honeycomb panel surface, such as wavy undulations and uneven textures, when the pressure block 1907 of the flexible connector 19 contacts the honeycomb panel surface; if there are protrusions, the pressure block 1907 is compressed, pushing the inner rod 1904 to slide upwards within the hollow outer rod 1901, compressing the return spring 1902, causing the pressure block 1907 to retract upwards; if there are depressions on the honeycomb panel surface, the return spring 1902 releases its elastic potential energy, pushing the inner rod 1904 to move the pressure block 1907 downwards, filling the depressed area. Each flexible connector 19 can be independently adjusted according to the surface morphology of the contact point, achieving a tight fit with the complex contours of the honeycomb panel. The continuously operating negative pressure pump 10 maintains the negative pressure adsorption state between the pressure block 1907 and the honeycomb panel surface through the vent 1903, further enhancing the bonding stability and preventing displacement of the honeycomb panel during the pressing process. At the same time, the flexible rubber pad 1908 contacts the honeycomb panel surface, and its soft material can increase the contact area, buffer pressure, and avoid scratching the honeycomb panel surface.

[0048] Under the continuous pressure of cylinder 3, the upper and lower honeycomb panels achieve tight surface adhesion and uniform force under the dual action of adaptive adjustment and negative pressure adsorption of flexible connector 19, thus completing a high-quality pressing process.

[0049] After pressing is completed, cylinder 3 drives the upper pressing plate 4 to move upward and reset, while the negative pressure pump 10 stops working, releasing the negative pressure adsorption on the honeycomb panel, allowing the operator to remove the pressed honeycomb panel. If there are residual colloids or other impurities on the surface of the lower pressing plate 6, it can be cleaned. After the cleaning fluid is sprayed or rinsed on the surface of the lower pressing plate 6, it flows naturally under the guidance of the inclined surface of the guide block 14, eventually flowing into the mounting cavity 15 directly below the lower pressing plate 6 inside the housing 1, and collecting in the recycling drawer 16 inside the mounting cavity 15. After the recycling drawer 16 is full of cleaning fluid, the operator can pull it out for centralized processing, and after cleaning, slide it back into the mounting cavity 15 for the next cleaning fluid recycling.
