Description

Technical Field

[0002] Due to the harsh working environment of aircraft, often operating under high temperature and humidity conditions, and the high susceptibility to foreign object impacts during flight, impact dent damage is common. Repairing dented honeycomb composite structures requires simultaneous consideration of panel and core removal, with core filling being the most challenging. This process can easily damage the core material and cause mismatches in the damaged area's lattice structure. Reliable repair technology is a key technology in the aerospace manufacturing industry. Cleaning is an indispensable step in preparing for honeycomb panel repair. However, directly grinding or cutting the honeycomb panel surface can cause fine dust and debris to accumulate inside the honeycomb cells. This not only makes subsequent cleaning more complicated but may also introduce non-destructive defects such as inclusions.

[0024] Example: See attached document Figure 1-13This embodiment provides a cleaning device for repairing damaged areas of a honeycomb panel, comprising: a control panel 1, an operating platform for placing the honeycomb panel 5 on the control panel 1, and an operating port on the operating platform; a clamping mechanism 2 for clamping the honeycomb panel 5 onto the operating platform; and a grinding mechanism 6, comprising a mounting platform 64, a grinding machine 65, a first drive assembly 63, and a second drive assembly 66. The grinding machine 65 is mounted on the mounting platform 64, the first drive assembly 63 is mounted on the operating platform and is used to drive the mounting platform 64 to move laterally so that the grinding machine 65 grinds the damaged area of ​​the honeycomb panel 5, and the second drive assembly 66 is mounted on the mounting platform 64 and is used to drive the grinding machine 65 to move up and down so that the top of the grinding machine 65 fits against the damaged area of ​​the honeycomb panel 5. Area; Reinforcement mechanism 7, which includes mounting strip 72, insertion tube 75 and fifth drive assembly 74. Multiple insertion tubes 75 are provided and are set on mounting strip 72. The fifth drive assembly 74 is set on mounting table 64 and is used to drive mounting strip 72 to move up and down so that insertion tube 75 is inserted into the honeycomb holes at the edge of the grinding range to reinforce the honeycomb holes; Air pipe 9, which is used to connect with external air supply equipment and communicates with insertion tube 75. The top of insertion tube 75 is provided with an air outlet communicating with air pipe 9; Observation mechanism 3, which is set on the operating table and observes the honeycomb plate 5 on the placement position through the operating port; Collection box 4, which is inserted into the operating table and is used to collect the debris generated during the grinding process.

[0025] In this embodiment, the control panel 1 is a rectangular box shape, which can be composed of a metal frame and a panel. An operating platform is provided on the control panel 1 for placing the honeycomb panel 5 to be processed. To facilitate operation and observation of the damaged area of ​​the honeycomb panel 5, the control panel 1 has an operating port on the operating platform. The operating platform can be a flat surface, and the operating port is a pre-reserved rectangular opening. The air pipe 9 is configured to connect to an external air supply device to introduce high-pressure gas. The observation mechanism 3 is located on the control panel, and its function is to observe the honeycomb panel 5 placed on the operating platform through the operating port. A collection box 4 is inserted into the control panel, and its function is to collect the debris generated during the grinding process. The collection box 4 can be a pull-out drawer-type container, and its interior can be equipped with a filter screen to facilitate the separation and cleaning of the collected debris.

[0026] In use, firstly, the operator places the damaged honeycomb panel 5 on the operating platform of the device, ensuring that the damaged area is directly below the operating port. Then, the clamping mechanism 2 securely fixes the honeycomb panel 5 to the operating platform. Next, the operator uses the observation mechanism 3 to conduct a preliminary observation of the damaged area of ​​the honeycomb panel 5, assessing the extent and depth of the damage. Based on the observation results, the operator will preliminarily determine the starting position and approximate range of the grinding. Subsequently, the grinding mechanism 6 is activated, and the operator uses the first drive component 63 to move the mounting table 64 laterally, thereby precisely positioning the grinding machine 65 to the starting position of the damaged area of ​​the honeycomb panel 5. Then, the height of the grinding head is adjusted by the second drive component 66 so that its top is in contact with the surface of the damaged area of ​​the honeycomb panel 5.

[0027] Before or simultaneously with the start of polishing, the operator moves the mounting strip 72 upward via the fifth drive assembly 74, thereby precisely inserting multiple inserts 75 into the honeycomb holes at the edge of the polishing area. The insertion of these inserts 75 provides physical support to the honeycomb hole walls, effectively preventing further damage or deformation of adjacent honeycomb hole structures due to vibration of the polisher 65 or material removal during the polishing process.

[0028] When the grinder 65 begins grinding the damaged area, the external air supply equipment is activated. High-pressure gas is delivered through the air pipe 9 to the insertion tube 75, which has been inserted into the honeycomb cell. Through the air outlet at the top of the insertion tube 75, the high-pressure airflow is directed into the honeycomb cell. As a result, while the grinder 65 is cutting the material, the fine dust and debris generated are promptly blown out of the honeycomb cell by the airflow, preventing these contaminants from accumulating inside the honeycomb cell. The continuous blowing of the airflow ensures the cleanliness of the inside of the honeycomb cell, significantly reducing the difficulty of subsequent cleaning and eliminating the risk of non-destructive defects that may be caused by impurities.

[0029] Throughout the grinding process, the operator continuously monitors the operating status and cleaning effect of the grinding machine 65 through the observation mechanism 3, and makes fine adjustments to the horizontal and vertical movement of the grinding machine 65 as needed to ensure that the damaged area is thoroughly cleaned. After grinding and cleaning are completed, the grinding mechanism 6 and the reinforcement mechanism 7 are reset, and the operator removes the collection box 4 from the control panel 1 to clean the grinding debris and dust blown out by the airflow.

[0030] The insertion tubes 75 in the reinforcement mechanism 7 are inserted into the honeycomb holes at the edge of the grinding area before or during grinding. This design not only provides physical support for the honeycomb hole walls, preventing secondary damage that may occur during grinding, but more importantly, these insertion tubes 75 also serve as airflow delivery channels. Through the air pipe 9 connected to the air outlet at the top of the insertion tube 75, high-pressure airflow can be precisely injected into the honeycomb holes while the grinder 65 is operating.

[0031] Compared to the passive vacuuming or post-cleaning methods used in existing technologies, the solution in this embodiment achieves active and real-time cleaning. While the material is being polished and cut, the generated dust and debris are blown out by the airflow and collected by the collection box 4. This simultaneous cleaning method prevents the deposition of contaminants inside the honeycomb cells at the source, greatly improving cleaning efficiency and thoroughness. Consequently, subsequent repair work can be carried out in a cleaner environment, significantly reducing the risk of repair defects caused by internal impurities, thereby improving the reliability and quality of the honeycomb panel 5 repair. The overall technical concept of this device, through the synergistic effect of its various mechanisms, provides an efficient, precise, and reliable solution for cleaning damaged areas of the honeycomb core.

[0032] As an optional implementation, the grinding mechanism 6 further includes a pad frame 62 and a slider 61. The mounting platform 64 is disposed on the slider 61, the pad frame 62 is disposed inside the operating opening, and the top of the pad frame 62 is higher than the operating platform to place the honeycomb plate 5. The slider 61 is slidably disposed inside the pad frame 62. The first drive assembly 63 includes a first lead screw 631, a first motor 632, and a slide rod 633. The slider 61 is disposed inside the operating platform, the first motor 632 is disposed on the side wall of the pad frame 62, one end of the first lead screw 631 is mounted on the output shaft of the first motor 632, the slider 61 is threadedly connected to the first lead screw 631, and both ends of the slide rod 633 are disposed on both sides of the pad frame 62 and are parallel to the first lead screw 631. The slider 61 is slidably connected to the slide rod 633.

[0033] In this embodiment, the pad frame 62 is a frame structure that provides a defined sliding track and support surface for the slider 61. The pad frame 62 can be rectangular, U-shaped, or other geometric shapes suitable for the movement of the slider 61. It is usually made of a material with certain strength and wear resistance. The pad frame 62 ensures the stable movement path of the slider 61 within the operating port and can effectively support the honeycomb panel 5. The top of the pad frame 62 is higher than the operating platform, which not only provides additional support for the placement of the honeycomb panel 5, but also provides a stable running frame for the slider 61.

[0034] When the first motor 632 rotates, the first lead screw 631 rotates accordingly, converting the rotational motion into the linear motion of the slider 61 through a threaded transmission mechanism, thereby driving the mounting table 64 to move laterally. To further improve the stability and accuracy of the movement, the two ends of the slide rod 633 are set on both sides of the pad frame 62 and kept parallel to the first lead screw 631, with the slider 61 slidably connected to the slide rod 633. This structure allows the slider 61 to be precisely guided in a straight line along the slide rod 633 under the drive of the first lead screw 631, effectively preventing any swaying, shaking, or jamming that may occur during the lateral movement of the mounting table 64. Through this precise combination of mechanical structures, the lateral movement of the grinding mechanism 6 can be controlled with high precision and high stability, thereby ensuring that the grinding machine 65 can accurately perform fine grinding on the damaged area of ​​the honeycomb panel 5, significantly improving the quality and efficiency of the repair operation.

[0035] As an optional implementation, the second drive assembly 66 includes a first electric push rod 661, a bracket 662, a second motor 663, a second lead screw 664, and a moving block 665. The bracket 662 is slidably disposed on the mounting platform 64. The first electric push rod 661 is disposed on the mounting platform 64, and the telescopic end of the first electric push rod 661 is connected to the bracket 662 to drive the bracket 662 to slide on the mounting platform 64. The second motor 663 is disposed inside the bracket 662. The second lead screw 664 is vertically disposed at the drive end of the second motor 663. The moving block 665 is threadedly connected to the second motor 663. The bracket 662 is provided with a vertically disposed moving groove for the moving block 665 to slide. The grinder 65 is disposed on the moving block 665.

[0036] In this embodiment, the bracket 662 is used to support the second motor 663, the second lead screw 664, and the moving block 665, and slides on the mounting platform 64. The bracket 662 can adopt an L-shaped, U-shaped, or box-shaped structure, and its material can be high-strength aluminum alloy, stainless steel, or engineering plastic to ensure sufficient rigidity and stability. The bracket 662 is mounted on the mounting platform 64 by a sliding fit, allowing the bracket 662 to move linearly on the surface of the mounting platform 64. This sliding fit can be achieved by a combination of guide rails and sliders 61, such as a grooved guide rail 734, a linear rolling guide rail, or a sliding bearing guide rail, to ensure the smoothness and accuracy of the movement of the bracket 662.

[0037] When it is necessary to adjust the height of the polisher 65 or to align it with the damaged area of ​​the honeycomb panel 5, the first electric push rod 661 receives a control signal and extends or retracts. Its retractable end is connected to the bracket 662, thereby driving the bracket 662 to slide on the mounting platform 64. The sliding of the bracket 662 provides the polisher 65 with fine-tuning capability in the horizontal direction. Alternatively, in some designs, the sliding of the bracket 662 may cooperate with the first drive assembly 63 to achieve more complex horizontal positioning. More importantly, inside the bracket 662, the second motor 663 drives the vertically arranged second lead screw 664 to rotate. The moving block 665, which is threadedly connected to the second lead screw 664, is precisely guided in the vertical moving groove on the bracket 662, achieving linear motion in the vertical direction.

[0038] Because the polishing machine 65 is mounted on the moving block 665, it can move up and down with high precision. This layered drive and fine-guided structure allows the polishing machine 65 to not only achieve basic up-and-down movement, but also to perform micron-level vertical position adjustments based on the actual conditions of the damaged area of ​​the honeycomb panel 5. This ensures that the top of the polishing machine 65 always precisely fits the damaged area and achieves precise control over the polishing depth. Compared to relying solely on a generalized up-and-down movement function, this solution, through a combination of electric push rods and lead screw drives, provides higher precision and stability for the vertical positioning of the polishing machine 65, effectively solving the problem of insufficient precision caused by surface unevenness or changes in depth requirements during the polishing process.

[0039] As an optional implementation, the fifth drive assembly 74 includes a fourth motor 742, a third lead screw 741, a base block 743, a telescopic rod 744, and a third electric push rod 745. The fourth motor 742 is mounted on the mounting platform 64. The third lead screw 741 is connected to the drive end of the fourth motor 742. The base block 743 is threadedly connected to the third lead screw 741. The mounting platform 64 is provided with a guide groove for sliding the base block 743. The telescopic rod 744 is vertically arranged on the base block 743 and multiple rods are provided. The mounting strip 72 is provided at the top of the telescopic rod 744. The third electric push rod 745 is vertically arranged on the mounting platform 64, and the top of the telescopic end of the third electric push rod 745 is connected to the mounting strip 72.

[0040] In this embodiment, the mounting platform 64 is provided with a guide groove for the sliding of the base block 743. This guide groove restricts the lateral freedom of the base block 743, ensuring that the base block 743 moves stably along a preset straight path. The guide groove can be a linear guide rail, achieving low-friction, high-precision linear motion through the cooperation of the slider 61 and the guide rail; alternatively, it can be a dovetail groove structure, providing good guidance and support through its self-locking characteristics. Multiple telescopic rods 744 are vertically mounted on the base block 743, used to transmit the vertical movement of the base block 743 to the mounting strip 72. The telescopic rods 744 can be multi-segment telescopic structures to achieve a large telescopic stroke within a compact space; alternatively, they can be simple fixed-length rods, with the overall movement of the base block 743 achieving the raising and lowering of the mounting strip 72. A third electric push rod 745 is vertically mounted on the mounting platform 64, with its telescopic end connected to the mounting strip 72, used to provide additional vertical driving force or for fine-tuning. The third electric actuator 745 can be a small linear electric actuator, which can achieve fine position adjustment of the mounting strip 72 or provide additional clamping force through its extension stroke; or it can be a pneumatic actuator, which can achieve rapid response and flexible drive through air pressure control.

[0041] When the vertical position of the mounting strip 72 needs adjustment, the fourth motor 742 starts and drives the third lead screw 741 to rotate. Since the base block 743 is threadedly connected to the third lead screw 741, the rotational motion of the third lead screw 741 is converted into linear motion of the base block 743. Simultaneously, the base block 743 slides within the guide groove on the mounting platform 64, ensuring smooth and unbiased vertical movement. Multiple telescopic rods 744 transmit the vertical movement of the base block 743 to the mounting strip 72, thereby driving the mounting strip 72 and its attached insertion tube 75 to rise and fall as a whole. Furthermore, the third electric push rod 745, acting as an auxiliary or fine-tuning mechanism, connects its telescopic end to the mounting strip 72, providing additional vertical driving force or allowing for micron-level fine adjustments to the final vertical position of the mounting strip 72. This ensures that the insertion tube 75 can be accurately and stably inserted into the honeycomb holes at the edge of the damaged area of ​​the honeycomb panel 5, providing reliable support.

[0042] This composite drive method combines the precision of screw drive with the flexibility of electric push rod, enabling the reinforcement mechanism 7 to adapt to various unevennesses that may exist in the damaged area of ​​the honeycomb panel 5. It achieves precise positioning and effective reinforcement of the honeycomb holes, effectively solving the unevenness problem that may exist in the damaged area of ​​the honeycomb panel 5. It ensures that the insertion tube 75 can be accurately and reliably inserted into the honeycomb holes for reinforcement, significantly improving the accuracy and stability of the reinforcement operation during the repair of damaged honeycomb cores, thereby ensuring the repair quality.

[0043] As an optional implementation, a second electric push rod 732 is provided inside the mounting strip 72. A pull bar 731 is provided at the telescopic end of the second electric push rod 732. Multiple movable tubes 77 are connected to the pull bar 731, and each movable tube 77 is connected to the air tube 9. Each movable tube 77 corresponds to and is slidably inserted into the insertion tube 75. The movable tube 77 communicates with the air outlet at the top of the insertion tube 75. A top ring 78 is provided near the top of each movable tube 77 inserted into the insertion tube 75. Multiple top blocks 76 are evenly inserted into the side wall of tube 5. The top blocks 76 are slidably disposed on the insertion tube 75 along the radial direction of the insertion tube 75. The outer wall of the top ring 78 is attached to the inner wall of the top block 76. The contact surface between the top block 76 and the top ring 78 is inclined. A rubber tube 79 is provided at the top end of the moving tube 77. The rubber tube 79 is connected to the moving tube 77. The top end of the rubber tube 79 is connected to the top end of the insertion tube 75. The moving tube 77 is connected to the air outlet through the rubber tube 79. The side wall of the rubber tube 79 is attached to the inner wall of the top block 76.

[0044] In this embodiment, the pull bar 731 is a long plate-shaped structural component used to connect the telescopic end of the second electric push rod 732 to multiple moving tubes 77. It transmits the linear motion of the second electric push rod 732 to all connected moving tubes 77, ensuring their synchronous movement. The pull bar 731 can be made of metal, plastic, or composite materials, and its design should ensure sufficient rigidity and lightweight. The moving tubes 77 are hollow tubular structures that communicate with the air tube 9 and are slidably inserted into the insertion tube 75. They are airflow channels responsible for delivering clean gas to the inside of the honeycomb pores. The moving tubes 77 can be made of materials such as metal, plastic, or ceramic, and their outer diameter should be slightly smaller than the inner diameter of the insertion tube 75 to ensure smooth sliding. The top ring 78 is an annular structure located near the top of the moving tube 77 inserted into the insertion tube 75. It cooperates with the top block 76 inside the insertion tube 75 to achieve radial movement of the top block 76 through the inclined plane when the moving tube 77 moves up and down. The top ring 78 can be made of metal or high-strength plastic, and its outer wall should be smooth to reduce friction.

[0045] The top block 76 is a block-shaped structure that slides radially along the insertion tube 75, evenly distributed on the side wall of the insertion tube 75. It cooperates with the top ring 78 and can move radially outward or inward when the moving tube 77 moves up and down, thereby changing the effective diameter inside the insertion tube 75 or achieving contact with the inner wall of the honeycomb cells. The top block 76 can be made of wear-resistant materials such as engineering plastics or metal. The surface of the top block 76 that contacts the top ring 78 is designed to be inclined. This inclined design utilizes the principle of inclined planes to convert the axial movement of the moving tube 77 into the radial movement of the top block 76, thereby achieving the expansion or contraction effect on the inner wall of the honeycomb cells. The design of the inclination angle affects the stroke of the radial movement and the required driving force. The rubber tube 79 is an elastic tubular connector located at the top end of the moving tube 77 and communicating with it. It connects the top end of the moving tube 77 to the top end of the insertion tube 75 and communicates with the vent. The elasticity of the rubber tube 79 allows it to adapt to the up-and-down movement of the moving tube 77 while maintaining the air passage's seal, and allows its sidewalls to conform to the inner wall of the top block 76, assisting in the radial movement of the top block 76. Besides rubber, other elastic materials such as silicone or polyurethane can also be used.

[0046] When the second electric push rod 732 drives the pull bar 731 to move the moving tube 77 up and down inside the insertion tube 75, the top ring 78 slides along the inclined surface of the top block 76. This sliding action converts the axial movement of the moving tube 77 into the radial movement of the top block 76, so that the top block 76 can periodically expand outward or contract inward. As the top block 76 expands outward, it can contact and scrape the inner wall of the honeycomb holes, helping to remove dust and debris adhering to the inner wall. At the same time, since the side wall of the rubber tube 79 is also attached to the inner wall of the top block 76, the rubber tube 79 will deform as the top block 76 expands, further assisting the cleaning effect and ensuring that the airflow can be effectively ejected through the air outlet, forming an impact and blowing on the inner wall of the honeycomb holes. This combination of radial movement and airflow makes the cleaning process no longer a simple straight-line blowing, but a dynamic and all-round cleaning of the inner wall of the honeycomb holes, which significantly improves the cleaning efficiency and thoroughness. In this way, the debris and dust generated during the polishing process can be removed more effectively, providing a clean base for subsequent repair work.

[0047] When grinding and reinforcing the damaged area of ​​the honeycomb panel 5, the insertion tube 75 in the reinforcement mechanism 7 not only provides support, but its internal cleaning mechanism is also significantly enhanced. The second electric push rod 732 drives the moving tube 77 to move up and down inside the insertion tube 75. Through the cooperation of the top ring 78 and the inclined surface of the top block 76, the radial expansion and contraction of the top block 76 is realized. This dynamic radial movement, combined with the airflow provided by the air tube 9, allows the cleaning gas to act more effectively on the inner wall of the honeycomb pores, scraping and blowing away the dust and debris attached to the inner wall. The elastic connection of the rubber tube 79 further ensures the airtightness of the air passage and the flexibility of cleaning, significantly improving the cleaning efficiency and quality inside the honeycomb pores, providing a cleaner and more reliable surface for subsequent filling of repair materials, thereby improving the overall repair effect and the durability of the honeycomb panel 5.

[0048] As an optional implementation, it also includes an adjustment mechanism 8, which includes a fourth electric push rod 81, a fixing bar 82, a control bar 83, and a scissor-type telescopic frame 84. The fourth electric push rod 81 is installed in the mounting bar 72 through the fixing bar 82. Multiple insertion tubes 75 are rotatably inserted through the intermediate shaft of the scissor-type telescopic frame 84 in a corresponding manner. The control bar 83 is rotatably connected to the insertion tubes 75 at the end of the scissor-type telescopic frame 84. The control bar 83 is connected to the telescopic end of the fourth electric push rod 81. The mounting bar 72 is provided with a long groove, and the multiple insertion tubes 75 are slidably disposed in the long groove. A moving rod 733 is connected to the moving tube 77. A sliding groove 734 is provided on one side of the pulling bar 731, and the end of the moving rod 733 is slidably disposed in the sliding groove 734.

[0049] In this embodiment, the scissor-type telescopic frame 84 is a mechanical structure that achieves telescopic or lifting functions through cross-connected links. Its basic principle is to utilize multiple X-shaped link units connected in series or parallel, driving the relative movement of one or more of these links to achieve changes in length or height while maintaining stability. The control bar 83 is a link or rod used to transmit force and motion. It is typically part of a mechanical linkage system, transmitting the motion or force of one component to another to achieve specific control functions. The control bar 83 can be designed as a rigid rod, a flexible cable, or a link with a specific geometry, and its connection method can be hinged, sliding, or fixed to adapt to different motion trajectories and force transmission requirements.

[0050] Multiple insertion tubes 75 are rotatably connected to the central shaft of the scissor-type telescopic frame 84 in a one-to-one correspondence. This connection allows the multiple insertion tubes 75 to rotate around the central shaft of the scissor-type telescopic frame 84. Simultaneously, as the scissor-type telescopic frame 84 extends and retracts, the relative spacing between the insertion tubes 75 changes accordingly, allowing the insertion tubes 75 to flexibly adjust their horizontal distribution while maintaining their own posture to adapt to honeycomb holes with different spacings. The control bar 83 is rotatably connected to the insertion tubes 75 at the end of the scissor-type telescopic frame 84. This connection ensures that the fourth electric push rod 81 can effectively drive the extension and retraction of the scissor-type telescopic frame 84 through the movement of the control bar 83. By rotatably connecting the control bar 83 to the insertion tubes 75 at the end of the scissor-type telescopic frame 84, synchronous driving of the entire scissor-type telescopic frame 84 can be achieved, thereby precisely controlling the overall spacing adjustment of the insertion tube 75 array. The control bar 83 is connected to the telescopic end of the fourth electric push rod 81. This connection method directly transmits the linear reciprocating motion of the fourth electric push rod 81 to the control bar 83, thereby driving the scissor-type telescopic frame 84.

[0051] Multiple insertion tubes 75 are slidably disposed within the elongated groove. This arrangement allows the insertion tubes 75 to slide along the length of the mounting strip 72, enabling them to smoothly move to new positions when the spacing of the scissor-type telescopic frame 84 is adjusted. This sliding fit ensures that the insertion tubes 75 will not be jammed during adjustment and maintains their vertical stability. A moving rod 733 is connected to the moving tube 77. The moving rod 733 is an auxiliary rod connected to the moving tube 77, and its function is to connect the movement of the moving tube 77 with an external drive or linkage mechanism, ensuring that the moving tube 77 can move synchronously with the spacing adjustment of the insertion tubes 75. The moving rod 733 can be fixed to the moving tube 77 by welding, threaded connection, or snap-fit ​​connection. A sliding groove 734 is provided on one side of the pull strip 731. The sliding groove 734 is used for... The elongated groove guiding the movement of the moving rod 733 provides a restricted movement path for the moving rod 733, ensuring that the moving rod 733 can slide in a predetermined direction under the action of the pull bar 731. The end of the moving rod 733 is slidably disposed in the slide groove 734, so that the end of the moving rod 733 can slide freely in the slide groove 734 of the pull bar 731. When the pull bar 731 moves, the slide groove 734 will drive the moving rod 733 to move synchronously, thereby ensuring that the moving tube 77 connected to the intubation tube 75 can move synchronously with the spacing adjustment of the intubation tube 75, maintaining effective communication between the trachea 9 and the intubation tube 75.

[0052] When the fourth electric push rod 81 is activated, its linear reciprocating motion drives the control bar 83. The control bar 83 then rotates and connects with the insertion tube 75 at the end of the scissor-type telescopic frame 84, thereby causing the entire scissor-type telescopic frame 84 to extend and retract. Since multiple insertion tubes 75 are rotated one-to-one through the intermediate shaft of the scissor-type telescopic frame 84, and these insertion tubes 75 are also slidably set in the long slot on the mounting bar 72, the extension and retraction movement of the scissor-type telescopic frame 84 will precisely change the relative spacing between the multiple insertion tubes 75, ensuring that the spacing adjustment of the insertion tubes 75 in the horizontal direction is both flexible and stable. At the same time, in order to ensure that the moving pipe 77 used for air supply can move synchronously during the spacing adjustment of the insertion tubes 75, the end of the moving rod 733 is slidably set in the slide groove 734. In this way, when the spacing of the endotracheal tubes 75 changes, the pull bar 731 will drive the moving rod 733 to slide in the groove 734, so that the moving tube 77 moves synchronously with the endotracheal tubes 75, ensuring that the connectivity between the trachea 9 and the endotracheal tubes 75 is not affected. Through the above-mentioned synergistic effect, the spacing of multiple endotracheal tubes 75 can be precisely and synchronously adjusted, so that the reinforcement mechanism 7 can flexibly adapt to honeycomb holes of different specifications or irregular arrangements, thereby significantly improving the success rate and efficiency of endotracheal tube 75 alignment and insertion.

[0053] As an optional implementation, the reinforcement mechanism 7 further includes a third drive assembly 71, which includes a first gear 711, a third motor 712, and a second gear 713. The first gear 711 is sleeved on the outer wall of the mounting platform 64, and the mounting platform 64 is rotatably mounted on the slider 61. The third motor 712 is mounted on the side wall of the slider 61, and the second gear 713 is mounted on the drive end of the third motor 712. The first gear 711 and the second gear 713 mesh.

[0054] In this embodiment, the first gear 711 is a passive gear, which is sleeved on the outer wall of the mounting platform 64 and is used to mesh with the second gear 713, thereby transmitting the rotational power of the third motor 712 to the mounting platform 64, and thus driving the mounting platform 64 to rotate; the second gear 713 is a driving gear, which is disposed at the drive end of the third motor 712 and is used to transmit the rotational motion of the third motor 712 to the first gear 711. The type of the second gear 713 should match that of the first gear 711.

[0055] When the third motor 712 starts, it drives the second gear 713 to rotate. The second gear 713 transmits rotational power to the first gear 711 through meshing with the first gear 711. Since the first gear 711 is fixed on the outer wall of the mounting platform 64, the mounting platform 64 will rotate accordingly. The rotation of the mounting platform 64 will then drive the reinforcement mechanism 7 mounted on it to make overall angular adjustments. This allows the reinforcement mechanism 7 to gain rotational adjustment capabilities in addition to horizontal and vertical movement capabilities. This enables the insertion tube 75 to be accurately aligned with the honeycomb holes on the honeycomb panel 5 at any angle or direction, greatly improving the flexibility and accuracy of the reinforcement operation.

[0056] The reinforcement mechanism 7 incorporates a third drive component 71, enabling the mounting platform 64 and its array of insertion tubes 75 to rotate. This solves the problem of the insertion tubes 75 array being difficult to precisely align with the honeycomb holes in different directions or angles when reinforcing the damaged area of ​​the honeycomb panel 5. Through the gear transmission driven by the third motor 712, the mounting platform 64 can be precisely adjusted in angle, allowing the insertion tubes 75 to be inserted into the honeycomb holes more flexibly and accurately. This improves the adaptability and efficiency of the reinforcement operation, ensures the accuracy of support for the inner wall of the honeycomb holes, and thus enhances the quality of cleaning and repairing the entire damaged area.

[0057] As an optional implementation, the pressing mechanism 2 includes a cover plate 22, a pressure plate 23 and a knob 21. The cover plate 22 is hinged to the operating table, the pressure plate 23 is slidably disposed on the inner side of the cover plate 22, and the knob 21 is threaded through the cover plate 22 and abuts against the pressure plate 23. Rotating the knob 21 pushes the pressure plate 23 to press the honeycomb plate 5 onto the pad frame 62.

[0058] In this embodiment, the pressure plate 23 is a plate-shaped component used to directly contact the honeycomb panel 5 and apply pressure. Its material can be selected to be a material that does not damage the surface of the honeycomb panel 5 and has a certain degree of friction, such as rubber, polyurethane, or a metal plate with padding. The lower surface of the pressure plate 23 can be designed to be flat or have a microstructure to increase the contact area and friction with the honeycomb panel 5. Similarly, the top of the pad frame 62 is also made of materials such as rubber or polyurethane to reduce damage to the honeycomb panel 5. The knob 21 is a device for adjusting or controlling mechanical components through rotation. It typically consists of a handle and a threaded rod. The handle facilitates manual operation, while the threaded rod engages with a threaded hole on the cover plate 22. The material of the knob 21 can be a wear-resistant metal or engineering plastic; the sliding arrangement of the pressure plate 23 inside the cover plate 22 allows the pressure plate 23 to move slightly horizontally or vertically according to the adjustment of the knob 21 after the cover plate 22 is closed. This sliding mechanism can use the cooperation of the guide rail and the slider 61, or a simple limiting groove structure. The threaded rod of the knob 21 cooperates with the threaded hole on the cover plate 22 to form a threaded transmission pair. When the knob 21 is rotated, the threaded rod will move along its axial direction, and its end will directly or through the intermediate part abut against the pressure plate 23. This structure allows the rotational motion of the knob 21 to be converted into a linear thrust on the pressure plate 23, thereby achieving the pressing of the honeycomb panel 5.

[0059] When the operator turns knob 21, the threaded motion of knob 21 is converted into a pushing force on pressure plate 23, thereby pushing pressure plate 23 downward and firmly pressing the honeycomb panel 5 placed on the pad frame 62. This allows the clamping force to be precisely adjusted according to the actual situation of the honeycomb panel 5, ensuring that the honeycomb panel 5 remains stable during the grinding process and avoiding the impact of displacement or vibration on the grinding accuracy. By stably pressing the honeycomb panel 5 onto the pad frame 62, the clamping mechanism 2 provides a solid operating foundation for the grinding mechanism 6, enabling the grinder 65 to accurately grind the damaged area of ​​the honeycomb panel 5. This effectively solves the problem of unstable fixation that may occur during the grinding process of the honeycomb panel 5, ensuring the quality and efficiency of the repair operation.

[0060] As an optional implementation, the observation mechanism 3 includes a dark box 31, a first transparent plate 32, a second transparent plate 33, a first reflector 34, and a second reflector 35. The dark box 31 is disposed through the side wall of the operating table. The first transparent plate 32 is disposed at the end of the dark box 31 located outside the operating table, and the end of the dark box 31 located outside the operating table is inclined upwards. The dark box 31 is located inside the operating table for observing the honeycomb panel 5. The second transparent plate 33 is inclinedly disposed at the end of the dark box 31 located inside the operating table. The first reflector 34 and the second reflector 35 are inclinedly disposed inside the dark box 31. The first reflector 34 is located below the first transparent plate 32, and the second reflector 35 is located below the second transparent plate 33. A lighting lamp 36 is disposed inside the dark box 31 between the first reflector 34 and the second reflector 35.

[0061] In this embodiment, the dark box 31 is a structure with a relatively enclosed internal space. Its function is to provide a light-controlled environment for the observation mechanism 3 to reduce the influence of external stray light on the observation effect. The dark box 31 can be made of opaque materials, such as metal, engineering plastics, or composite materials. Its shape and size can be designed according to the actual installation space and observation needs, such as cuboid, cylinder, or irregular shape. The first transparent plate 32 is a light-transmitting component set at one end of the dark box 31. Its main function is to allow the observer or external imaging equipment to observe through it while maintaining the relative enclosure of the internal environment of the dark box 31. The second transparent plate 33 is a light-transmitting component set at an angle at one end of the dark box 31. Its function is to act as an interface in the light path, allowing light from the honeycomb plate 5 to enter the interior of the dark box 31 and to change the direction of the light path in conjunction with the reflector. The first transparent plate 32 and the second transparent plate 33 can be made of materials with high light transmittance, such as glass, polycarbonate, or acrylic, to ensure image clarity.

[0062] The first reflector 34 is tilted inside the dark box 31, below the first transparent plate 32. Its main function is to change the direction of light propagation and reflect the light from the second reflector 35 back to the direction of the first transparent plate 32, thereby transmitting the image of the honeycomb plate 5 to the observer. The second reflector 35 is tilted inside the dark box 31, below the second transparent plate 33. Its main function is to receive the light from the honeycomb plate 5 and reflect it back to the direction of the first reflector 34, so as to realize the folding of the light path and the transmission of the image. The first reflector 34 and the second reflector 35 can be plane mirrors, prisms or optical lenses with specific reflective coatings.

[0063] The lighting lamp 36 is installed inside the dark box 31, between the first reflector 34 and the second reflector 35. Its function is to provide sufficient illumination for the damaged area of ​​the honeycomb panel 5, so that details can be clearly seen during observation, especially in low light environments. The lighting lamp 36 can use LED beads, fiber optic lighting or small halogen lamps as light sources, and its position and angle can be adjusted to achieve the best lighting effect.

[0064] The end of the dark box 31 where the first transparent plate 32 is installed is tilted upwards to facilitate observation by the operator. Since the fragments and dust generated during the polishing process will fall directly onto the second transparent plate 33, the second transparent plate 33 is tilted on the dark box 31. After the fragments and dust fall onto the second transparent plate 33, they will fall into the collection box 4 along with the tilted second transparent plate 33, which can reduce the situation where the dust accumulated on the second transparent plate 33 makes it impossible to observe clearly.

[0065] The observation mechanism 3 effectively solves the problem of difficulty in clearly observing the damaged area of ​​the honeycomb panel 5 due to limited operating space and insufficient light during the repair of damaged honeycomb cores. It adopts an optical structure of dark box 31, double transparent plate and double reflector, which not only realizes the folding of the light path, so that a wide and clear field of view can be obtained even in the compact device, but also ensures that the light in the observation environment is sufficient and stable through the light shielding effect of dark box 31 and the assistance of internal lighting lamp 36, which greatly improves the clarity and accuracy of observation. This allows the operator to more accurately assess the degree and extent of damage to the honeycomb panel 5, and provides reliable visual guidance for subsequent repair steps such as polishing, cleaning and reinforcement, thereby improving the efficiency and quality of the entire repair process.

[0066] This embodiment also provides a method for cleaning damaged areas for repairing damaged honeycomb cores, including the following steps: S1. Place the damaged honeycomb panel 5 on the pad frame 62, so that the damaged area is located inside the operating port, and fix the honeycomb panel 5 by the clamping device. The damaged honeycomb panel 5 is placed on the pad frame 62, with the damaged area located within the operating opening. The honeycomb panel 5 is then fixed in place using a clamping device. This step aims to provide a stable and accurately positioned working platform for subsequent repair operations. Placing the damaged honeycomb panel 5 on the pad frame 62 ensures stable support, and the design of the top of the pad frame 62 being higher than the operating platform facilitates precise positioning of the honeycomb panel 5. Positioning the damaged area within the operating opening facilitates observation by the observation mechanism 3 and operation by the grinding mechanism 6 and the reinforcement mechanism 7. Fixing the honeycomb panel 5 using the clamping device effectively prevents displacement or vibration during grinding, thus ensuring grinding accuracy and safety. The clamping device can take various forms, such as mechanical clamps, vacuum suction, or bolt fixing.

[0067] S2. The damaged area of ​​the honeycomb panel 5 is observed through the observation mechanism 3. Based on the observation, the first screw 631 is driven to rotate by the first motor 632. The grinding machine 65 moves laterally to below the damaged area of ​​the honeycomb panel 5. The grinding machine 65 is moved by the first electric push rod 661 to grind and cut various parts of the honeycomb panel 5. The second drive assembly 66 drives the grinding machine 65 to move up and down to control the depth of grinding and cleaning. The observation mechanism 3 observes the damaged area of ​​the honeycomb panel 5. Based on the observation, the first motor 632 drives the first lead screw 631 to rotate, and the grinding machine 65 moves laterally to below the damaged area of ​​the honeycomb panel 5. The first electric push rod 661 moves the grinding machine 65 to grind and cut various parts of the honeycomb panel 5. The second drive assembly 66 drives the grinding machine 65 to move up and down, controlling the grinding depth. This step describes the initial stage and depth control of the grinding operation. The observation mechanism 3 is used to acquire real-time images or data of the damaged area so that the operator can assess the degree of damage and plan the grinding path. Based on the observation results, the first motor 632 drives the first lead screw 631 to rotate, causing the slider 61 and the mounting table 64 to move laterally, so that the grinding machine 65 is precisely positioned below the damaged area of ​​the honeycomb panel 5. The first electric push rod 661 further drives the grinding machine 65 to move, covering all parts of the damaged area for grinding and cutting. The second drive assembly 66 is responsible for controlling the vertical movement of the grinding machine 65, thereby precisely controlling the grinding depth and ensuring that only the damaged part is removed without damaging the healthy structure.

[0068] S3. During the process of controlling the grinding depth, the mounting table 64 is driven by the third drive component 71 to move the insertion tube 75 to below the edge of the grinding area. The bottom block 743 is moved to align the insertion tube 75 with the honeycomb hole at the edge of the grinding area. The mounting strip 72 is moved upward by the third electric push rod 745 to insert the insertion tube 75 into the honeycomb hole and support the inner wall of the honeycomb hole of the honeycomb plate 5. During the grinding depth control process, the mounting table 64 is rotated by the third drive assembly 71, causing the insertion tube 75 to move below the edge of the grinding area. The drive block 743 moves, aligning the insertion tube 75 with the honeycomb holes at the edge of the grinding area. The third electric push rod 745 moves the mounting strip 72 upwards, inserting the insertion tube 75 into the honeycomb holes to support the inner wall of the honeycomb holes in the honeycomb plate 5. This step is a key innovation of this method, aiming to reinforce and support the honeycomb holes during grinding. Simultaneously with controlling the grinding depth, the third drive assembly 71 drives the mounting table 64 to rotate, enabling the insertion tube 75 of the reinforcement mechanism 7 to move precisely below the edge of the grinding area. Subsequently, by moving the drive block 743, the position of the insertion tube 75 is further fine-tuned to precisely align it with the honeycomb holes at the edge of the grinding area. Then, the third electric push rod 745 drives the mounting strip 72 to move upward, inserting multiple insertion tubes 75 into the corresponding honeycomb holes. These insertion tubes 75 provide support on the inner wall of the honeycomb holes, effectively preventing the honeycomb holes from deforming or being damaged due to force during the grinding process. Especially when grinding the edge area, it can maintain the integrity of the honeycomb structure.

[0069] S4. After supporting the honeycomb holes at the edge of the grinding area, drive the grinding machine 65 to grind the damaged area. During the grinding process, air is supplied to the air pipe 9 through the external air supply device, and air is blown into the honeycomb holes through the air outlet on the insertion tube 75 to blow out the dust in the honeycomb holes. After supporting the honeycomb holes at the edge of the grinding area, the grinding machine 65 is driven to grind the damaged area. During the grinding process, air is supplied to the air pipe 9 through an external air supply device, and air is blown into the honeycomb holes through the air outlet on the insertion tube 75 to blow out the dust inside the honeycomb holes. This step describes the formal grinding and simultaneous cleaning under reinforced support. Once the honeycomb holes are effectively supported, the grinding machine 65 can safely grind the entire damaged area. During this process, in order to keep the working area clean and prevent grinding debris and dust from affecting the grinding effect or entering the depth of the honeycomb structure, the external air supply device will continuously supply air to the air pipe 9. This air is precisely blown into the honeycomb holes through the air outlet on the insertion tube 75, forming an airflow that blows out the dust and debris generated during the grinding process in a timely manner, preventing them from accumulating inside the honeycomb holes, thereby improving cleaning efficiency and the quality of subsequent repairs.

[0070] S5. After polishing is complete, remove the collection box 4 from the workbench and clean away the collected polishing debris, dust, etc.

[0071] After grinding is completed, the collection box 4 is removed from the operating table, and the collected grinding debris, dust, etc. are cleaned up. This step is the final work of the entire cleaning process. After all grinding and blowing operations are completed, the collection box 4 is removed from the operating table. The collection box 4 has collected most of the debris and dust generated during the grinding process. After removal and cleaning, it is convenient to dispose of waste, keep the equipment and working environment clean, and prepare for the next operation.

[0072] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
