Description

Technical Field

[0001] The present invention relates to the technical field of aircraft structural parts, and in particular to an aircraft boarding door debugging device and a debugging method based on a roller lock. Background Art

[0002] As a critical component of the aircraft's fuselage structure, the reliability of an aircraft's boarding door is directly linked to the safety of those on board. The door lock mechanism, a core component, is crucial for maintaining the door's airtightness, pressure resistance, and structural stability during flight. However, there are no dedicated debugging devices or methods for aircraft boarding doors, which utilize roller lock assemblies and load-bearing blocks as their locking mechanism.

[0003] The existing debugging process consists of three phases. First, the boarding door is assembled according to the product drawings, and the roller lock mechanism is manually positioned and installed on the boarding door. The second phase involves functional verification through trial installation of the door, visually observing and tactilely assessing the uniformity of the roller lock mechanism's force. The third phase, based on past debugging experience, adjusts the position of the load-bearing block to meet the required step difference based on the direction of the door's step difference. The entire process requires repeated disassembly and assembly to verify the debugging results.

[0004] During the above-mentioned debugging process, the error in manual positioning leads to axial deviation between the load-bearing block and the roller lock, which is difficult to eliminate, affecting the uniformity of the force on the roller lock mechanism. In severe cases, it may cause the roller lock to break, increasing unnecessary rework cycles and manufacturing costs; the debugging quality is overly dependent on the operator's experience and skill level, and there are significant differences in the debugging results of different operators, and the debugging quality cannot be guaranteed; the debugging efficiency is low, and a single hatch requires multiple people to jointly debug, and the debugging cycle is long, which increases labor costs and time costs. Summary of the Invention

[0005] The main purpose of the present invention is to provide an aircraft boarding door debugging device and debugging method based on a roller lock, aiming to solve the problem that the axis deviation of the roller lock is difficult to be effectively reduced in the prior art.

[0006] To achieve the above-mentioned object, the present invention provides an aircraft boarding door debugging device based on a roller lock, the device comprising: A roller lock assembly is provided on the door body of the boarding door, a lock shaft is provided in the roller lock assembly, and a positioning guide hole is provided on the roller lock assembly; An adjustment component, provided on the roller lock component, for adjusting the angle of the lock shaft; A first positioning assembly is used to form a positioning hole on the door body of the boarding door; the positioning hole cooperates with the positioning guide hole to achieve positioning of the roller lock assembly on the door body; a second positioning assembly, wherein a latch assembly is disposed therein, and the latch assembly cooperates with the lock shaft to fix the lock shaft at a theoretical angle; wherein the theoretical angle is the angle at which the lock shaft and the adjustment assembly need to be fixed; The measuring assembly is used to measure the angle of the second positioning assembly relative to the roller lock assembly.

[0007] Based on the above structure, the present invention provides an aircraft boarding door debugging device based on a roller lock, in which a positioning hole is directly made on the door body through a first positioning component; a coordinated hole is formed with the positioning guide hole pre-processed by the roller lock component, and the theoretical coordinates are converted into a physical reference. During operation, the positioning hole and the guide hole are mechanically aligned by pins or bolts, eliminating the axis deviation caused by manual assembly, ensuring that the installation position of the roller lock component on the door body is consistent with the design theoretical value, thereby avoiding misalignment of the load-bearing block and the lock shaft.

[0008] In addition, precise control of the lock shaft angle is achieved through the linkage between the adjustment component and the second positioning component. Specifically, the angle positioning structure composed of the pin component and the measuring component first measures the theoretical angle value, and then directly converts the theoretical angle into a physical positioning reference through the mechanical coordination of the pin component and the lock shaft, so that the angle adjustment process is completely quantified, eliminating the uncertainty caused by subjective judgment. It can be understood that the adjustment component not only realizes the mechanical linkage of the two roller lock components, but its length adjustment function also forms a closed-loop control with the angle positioning to ensure the overall coordination of the system.

[0009] Optionally, it is characterized in that the adjustment assembly includes a connecting rod, an adjustment hole is provided on the lock shaft, and the end of the connecting rod cooperates with the adjustment hole.

[0010] Optionally, the free end of the connecting rod is also connected to a lock shaft of another roller lock assembly.

[0017] Optionally, the steps between installing the roller lock assembly on the door body and connecting the two roller lock assemblies using the adjustment assembly further include: Align the positioning holes with the positioning guide holes and secure them.

A positioning hole is directly made on the door body by a first positioning assembly; a coordination hole is formed with the positioning guide hole pre-machined in the roller lock assembly, and theoretical coordinates are converted into physical references. During operation, the positioning hole and the guide hole are mechanically aligned by a pin or bolt, eliminating axis deviation caused by manual assembly, ensuring that the installation position of the roller lock assembly on the door body is consistent with the designed theoretical value, thereby avoiding misalignment between the load-bearing block and the lock shaft. In addition, precise control of the lock shaft angle is achieved through the linkage between the adjustment component and the second positioning component. Specifically, the angle positioning structure composed of the pin component and the measuring component first measures the theoretical angle value, and then directly converts the theoretical angle into a physical positioning reference through the mechanical coordination of the pin component and the lock shaft, so that the angle adjustment process is completely quantified, eliminating the uncertainty caused by subjective judgment, and solving the problem that the axis deviation of the roller lock in the prior art is difficult to effectively reduce. It can also be understood that the adjustment component not only realizes the mechanical linkage of the two roller lock components, but its length adjustment function also forms a closed-loop control with the angle positioning to ensure the overall coordination of the system.

In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time.

When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0026] It should be understood that in the present application, the rotating, sliding, meshing and other moving parts are well lubricated, and their outsides are provided with corresponding protective shells. However, in the drawings of the present application, in order to clearly indicate the connection status of the moving parts, they are not shown. It can also be understood that each component in the present application is made of metal or plastic materials with adaptable strength in the field to which it belongs to ensure that its structural rigidity meets actual needs.

[0027] In order to make the technical solutions of the present invention clearer, the abbreviations or key terms involved in the present invention are explained here, among which: An aircraft boarding door is a movable part on the aircraft fuselage used for passengers to board and disembark. The door can be opened and closed, locked, and unlocked by manual operation or a hydraulic system. The roller lock mechanism is a mechanism used to lock and unlock the aircraft boarding door. It consists of a roller lock assembly, an adjustment assembly, a load-bearing block, etc. The load-bearing block is a part installed on another aircraft structure. When the aircraft boarding door is locked, the load-bearing block contacts the lock shaft of the roller lock assembly, generating a force on the lock shaft in the opposite direction of the aircraft boarding door opening, thereby locking the aircraft boarding door.

[0028] Example 1: Please refer to the attached Figures 1 to 3 In this embodiment, a device for debugging an aircraft boarding door based on a roller lock is provided, the device comprising: A roller lock assembly 1 is provided on a door body 2 of a boarding gate. A lock shaft 4 is provided in the roller lock assembly 1 and a positioning guide hole is provided on the roller lock assembly 1. An adjustment component 3 is provided on the roller lock component 1 and is used to adjust the angle of the lock shaft 4; The first positioning assembly 5 is used to form a positioning hole on the door body 2 of the boarding gate; the positioning hole cooperates with the positioning guide hole to achieve the positioning of the roller lock assembly 1 on the door body 2; a second positioning assembly 7, wherein a latch assembly 8 is provided therein, and the latch assembly 8 cooperates with the lock shaft 4 to fix the lock shaft 4 at a theoretical angle; wherein the theoretical angle is the angle at which the lock shaft 4 and the adjustment assembly 3 need to be fixed; The measuring component is used to measure the angle of the second positioning component 7 relative to the roller lock component 1.

[0029] It should be noted that the existing debugging method is mainly divided into three stages. First, the boarding door body 2 is assembled according to the product drawings, and the roller lock mechanism is installed on the boarding door body 2 through manual positioning. The second stage is to verify the function through trial installation of the cabin door, and the force uniformity of the roller lock mechanism is judged by visual observation and feel. The third stage is based on previous debugging experience and adjusts the position of the load-bearing block to meet the step difference requirements according to the direction of the step difference of the door body 2. The entire process requires repeated disassembly and assembly to verify the debugging effect.

[0030] During the above-mentioned debugging process, the error in manual positioning leads to axial deviation between the load-bearing block and the roller lock, which is difficult to eliminate, affecting the uniformity of the force on the roller lock mechanism. In severe cases, it may cause the roller lock to break, increasing unnecessary rework cycles and manufacturing costs; the debugging quality is overly dependent on the operator's experience and skill level, and there are significant differences in the debugging results of different operators, and the debugging quality cannot be guaranteed; the debugging efficiency is low, and a single hatch requires multiple people to jointly debug, and the debugging cycle is long, which increases labor costs and time costs.

[0031] Based on the above problems, this embodiment provides an aircraft boarding door debugging device based on a roller lock, in which a positioning hole is directly made on the door body 2 through a first positioning component 5; a coordination hole is formed with the positioning guide hole pre-processed by the roller lock component 1, and the theoretical coordinates are converted into a physical reference. During operation, the positioning hole and the guide hole are mechanically aligned by pins or bolts, eliminating the axis deviation of manual assembly, ensuring that the installation position of the roller lock component 1 on the door body 2 is consistent with the design theoretical value, thereby avoiding misalignment of the load-bearing block and the lock shaft 4.

[0032] In addition, precise control of the angle of the lock shaft 4 is achieved through the linkage between the adjustment component 3 and the second positioning component 7. Specifically, the angle positioning structure composed of the pin component 8 and the measuring component first measures the theoretical angle value, and then directly converts the theoretical angle into a physical positioning reference through the mechanical coordination of the pin component 8 and the lock shaft 4, so that the angle adjustment process is completely quantified, eliminating the uncertainty caused by subjective judgment. It can be understood that the adjustment component 3 not only realizes the mechanical linkage of the two roller lock components 1, but its length adjustment function also forms a closed-loop control with the angle positioning to ensure the overall coordination of the system.

[0033] In this embodiment, the adjustment assembly 3 includes a connecting rod, and an adjustment hole is provided on the lock shaft 4, and the end of the connecting rod is matched with the adjustment hole.

[0034] It is understood that the connecting rod is preferably attached Figure 1In the prior art, the operator must determine the angle of the lock shaft 4 by feel, which is not only inefficient but also results vary significantly between operators. This embodiment creatively transforms angle adjustment into quantifiable mechanical motion by precisely machining an adjustment hole on the lock shaft 4 and forming a rigid connection with the adjustable connecting rod. When the connecting rod end is inserted into the adjustment hole, the change in its length is directly converted into a change in the rotational angle of the lock shaft 4. This mechanical transmission relationship makes the angle adjustment process predictable and repeatable.

[0035] In some embodiments, the matching of the connecting rod and the adjustment hole adopts a transition fit tolerance, which not only ensures the accuracy of transmission but also avoids the assembly difficulty caused by over-tight fit, and achieves a balance between operational convenience and adjustment accuracy.

[0036] It is also understood that when the angle of the lock shaft 4 needs to be adjusted, it is only necessary to change the effective length of the connecting rod. This length change is converted into torque through the contact surface between the adjustment hole and the connecting rod, thereby driving the rotation of the lock shaft 4. Because the connecting rod connects two roller lock assemblies 1 at the same time, it ensures the synchronous adjustment of multiple lock shafts 4, avoiding the cumulative errors caused by adjusting each one individually in the traditional method.

[0037] In some embodiments, the adjustment hole is opened on the upper end surface of the lock shaft 4. In this embodiment, the free end of the connecting rod is also connected to the lock shaft 4 of another roller lock assembly 1. It is understandable that effective synchronization cannot be achieved when adjusting roller lock assemblies 1. Specifically, in traditional debugging methods, each roller lock assembly 1 needs to be adjusted individually, which is not only time-consuming and labor-intensive, but also difficult to ensure the angular consistency of multiple lock shafts 4. Ultimately, this leads to uneven force when the roller lock contacts the load-bearing block, seriously affecting the airtightness and structural stability of the hatch. In contrast, this embodiment, by rigidly connecting the free end of the connecting rod to the lock shaft 4 of the adjacent roller lock assembly 1, creatively integrates multiple independent components into a coordinated system. When the angle of one lock shaft 4 is adjusted, this change is directly transmitted to the adjacent lock shaft 4 through the connecting rod, achieving synchronized movement of multiple lock shafts 4. This effectively ensures that all roller lock assemblies 1 maintain the same angular change rate during debugging, minimizing the cumulative error caused by individual adjustments.

[0038] In this embodiment, the lock shaft 4 is provided with a latch hole 10, and the latch assembly 8 cooperates with the latch hole 10. In traditional debugging methods, the angle of the lock shaft 4 relies primarily on the operator's feel and temporary fixation. This not only makes it difficult to ensure accuracy, but also easily causes displacement during subsequent use, resulting in changes in the contact state between the roller lock and the load-bearing block, affecting the door's sealing performance and service life. In this embodiment, by precisely machining the latch hole 10 on the lock shaft 4 and forming a tight fit with the latch assembly 8, the theoretical angle value is converted into a physical positioning reference. Once the latch assembly 8 is inserted into the latch hole 10, the rotational freedom of the lock shaft 4 is completely restricted, ensuring that it always maintains the preset angle during operation. Compared to the original temporary fixation method, the technical solution in this embodiment reduces the problem of angle drift of the lock shaft 4.

[0039] In this embodiment, the device further includes a first support beam 6 , which is fixedly connected to the door body 2 , and the first support beam 6 is fixedly connected to the first positioning assembly 5 .

[0040] It is understandable that in traditional debugging methods, the positioning tool is often directly installed on the door body 2 or on a temporary bracket, which is greatly affected by the deformation of the door body 2 and external vibrations, resulting in measurement reference drift, which seriously affects the debugging accuracy. Based on the above structure, an independent and stable installation platform is provided for the second positioning component 7 by forming a rigid connection between the second support beam 9 and the door body 2. Separating the measurement reference system from the work object while maintaining a certain relative position relationship reduces the impact of tool vibration and deformation of the door body 2 on the debugging accuracy. The second support beam 9 is made of high-strength alloy material, and its cross-sectional shape is optimized to control its own weight while ensuring rigidity. It will not cause additional load to the door body 2, and can effectively suppress external vibration interference.

[0041] In this embodiment, the device further includes a second support beam 9 , which is fixedly connected to the door body 2 , and the second support beam 9 is fixedly connected to the second positioning assembly 7 .

[0042] Similarly, by introducing the second support beam 9 as an intermediate structural layer, a stable mechanical transmission path is established between the door body 2 and the positioning tool. The second support beam 9 is made of high-strength alloy material and is precisely processed. Its cross-sectional shape has been optimized by finite element method and has the best stiffness-to-mass ratio in the X, Y and Z directions. When the second support beam 9 is rigidly connected to the door body 2 through multiple high-strength bolts, a stable reference platform independent of the local deformation of the door body 2 is actually constructed. The installation accuracy of the second positioning component 7 is no longer affected by the welding deformation or assembly stress of the door body 2. Even when the door body 2 is loaded and deformed, the support beam system can still maintain the stability of the measurement reference.

[0043] In this embodiment, the second positioning assembly 7 includes a latch seat 11 , and two ends of the latch seat 11 are connected to the latch assembly 8 and the second support beam 9 respectively.

[0044] Based on the above structure, a short-path, high-rigidity connection system is established between the second support beam 9 and the latch assembly 8 by introducing the latch seat 11. During actual debugging, the technicians first fix the latch seat 11 to the preset position of the second support beam 9 with high-strength bolts. At this time, the reference surface of the latch seat 11 forms a gap-free fit with the mounting surface of the support beam. The azimuth angle of the latch seat 11 is then calibrated using a laser tracker to ensure that it maintains a precise parallel relationship with the theoretical axis. Finally, the latch assembly 8 is inserted into the conical positioning hole of the latch seat 11 to achieve precise centering. The entire installation process achieves precise angle transmission from the support beam reference to the working end of the latch. Compared with the existing technology of directly installing the latch on a simple bracket, the angle transmission accuracy is effectively improved.

[0045] In this embodiment, the measuring component includes a laser tracker.

[0046] As can be understood, the use of a laser tracker as the core measurement component, utilizing the principles of laser interferometry and a precision angle encoder, enables non-contact, high-precision measurement of the spatial posture of the locking shaft 4. Specifically, the laser tracker emits a laser beam to a reflective target sphere mounted on the locking shaft 4, capturing the target sphere's spatial position changes in real time. This improves accuracy by two orders of magnitude compared to traditional mechanical measurement methods. This optical measurement method completely avoids component deformation and human interference caused by contact measurement, ensuring the objectivity and accuracy of the measurement data.

[0047] Example 2: As attached Figure 4 As shown, this embodiment provides a debugging method, which includes the following steps: Use the first positioning component 5 to make a positioning hole on the door body 2; Install the roller lock assembly 1 on the door body 2, and then use the adjustment assembly 3 to connect the two roller lock assemblies 1; Use the measuring component to measure the angle of the second positioning component 7 on the second support beam 9, and install the second positioning component 7 at the theoretical angle and fix it; Then, the latch assembly 8 is matched with the latch hole 10 to fix the lock shaft 4 according to the theoretical angle.

[0048] It should be noted that a high-precision positioning hole is made on the door body 2 by the first positioning component 5. This step solves the problem of large positioning errors in the original manual marking. The first positioning component 5 is made of a special alloy material, and its guide structure is precisely machined to ensure that the dimensional accuracy and position accuracy of the positioning hole are controlled within ±0.05mm; during the installation stage of the roller lock component 1, the adjustment component 3 is designed to enable the two roller locks to achieve mechanical linkage, changing the original inefficient mode of independent adjustment one by one. A laser tracker is used as an angle measurement tool to achieve non-contact high-precision measurement of the angle of the second positioning component 7. In the final stage of pin fixing, the precise matching design of the pin component 8 and the pin hole 10 ensures long-term stability after the angle is fixed. The pin is made of hardened steel and is precisely ground, and the matching clearance with the pin hole 10 is extremely low.

[0049] In this embodiment, The steps between installing the roller lock assembly 1 on the door body 2 and connecting the two roller lock assemblies 1 using the adjustment assembly 3 further include: Align the positioning holes with the positioning guide holes and secure them.

[0050] It should be noted that high-precision positioning holes are pre-made on the door body 2, and matching positioning guide holes are processed on the roller lock assembly 1 to construct a mechanical coordinated positioning system. When the positioning holes and the positioning guide holes are precisely aligned, they are fixed with positioning pins; the positioning holes are directly processed on the door body 2 using a CNC machine tool, and their position accuracy is strictly calibrated by a laser tracker; the positioning guide holes are completed by precision fixture processing during the manufacturing stage of the roller lock assembly 1 to ensure that the relative position relationship with the functional structure of the component fully meets the design requirements.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
