Description

Technical Field

[0001] This invention relates to the field of aircraft structural components technology, and in particular to an aircraft boarding door debugging device and debugging method based on a roller lock. Background Technology

[0002] As a critical component of the aircraft fuselage structure, the reliability of aircraft boarding doors is directly related to the safety of passengers. The boarding door locking mechanism, as a core component of the door, plays a vital role in maintaining the door's airtightness, pressure resistance, and structural stability during flight. For aircraft boarding doors using roller lock assemblies and load-bearing blocks as their locking mechanism, there are no specific debugging devices or methods.

[0003] The existing debugging plan mainly consists of three stages. First, the boarding gate body is assembled according to the product drawings, and the roller lock mechanism is manually positioned and installed on the gate body. Second, functional verification is conducted through trial assembly of the gate, judging the uniformity of force distribution on the roller lock mechanism based on visual observation and tactile assessment. Third, based on previous debugging experience, the position of the load-bearing blocks is adjusted to meet the step difference requirements according to the direction of the step difference deviation. The entire process requires repeated disassembly and reassembly to verify the debugging effect.

[0004] During the aforementioned debugging process, errors in manual positioning caused deviations between the load-bearing block and the roller lock axis, which were difficult to eliminate. This affected the uniformity of force distribution on the roller lock mechanism and, in severe cases, could lead to the roller lock breaking, increasing unnecessary rework cycles and manufacturing costs. Debugging quality was overly dependent on the operator's experience and skill level, with significant differences in debugging results among different operators, making it impossible to guarantee debugging quality. Debugging efficiency was low, requiring multiple people to work together to debug a single hatch, and the debugging cycle was long, increasing labor and time costs. Summary of the Invention

[0005] The main objective of this invention is to provide an aircraft boarding door adjustment device and adjustment method based on a roller lock, aiming to address the problem that the axial deviation of roller locks is difficult to effectively reduce in the prior art.

[0006] To achieve the above objectives, the present invention provides an aircraft boarding door adjustment device based on a roller lock, the device comprising: A roller lock assembly is installed on the door of the boarding gate. The roller lock assembly has a locking shaft inside and a positioning guide hole. An adjustment component, disposed on the roller lock assembly, is used to adjust the angle of the lock shaft; The first positioning component is used to create a positioning hole on the door body of the boarding gate; the positioning hole cooperates with the positioning guide hole to realize the positioning of the roller lock component on the door body; The second positioning component includes a pin assembly that engages with the locking shaft to fix the locking shaft at a theoretical angle; wherein the theoretical angle is the angle at which the locking shaft, together with the adjustment component, needs to be fixed. A measuring component for measuring the angle of the second positioning component relative to the roller lock component.

[0007] Based on the above structure, the present invention provides an aircraft boarding door debugging device based on a roller lock. The first positioning component directly produces positioning holes on the door body; these holes cooperate with the pre-machined positioning guide holes of the roller lock component to transform theoretical coordinates into physical references. During operation, the positioning holes and guide holes are mechanically aligned by pins or bolts, eliminating axial deviations caused by manual assembly and ensuring that the installation position of the roller lock component on the door body is consistent with the design theoretical value, thereby avoiding misalignment between the load-bearing block and the lock shaft.

[0008] Furthermore, precise control of the locking 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 cooperation between the pin component and the locking shaft. This makes the angle adjustment process completely quantifiable and eliminates the uncertainty caused by subjective judgment. It can be understood that the adjustment component not only realizes the mechanical linkage between 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, the adjusting assembly includes a connecting rod, the locking shaft is provided with an adjusting hole, and the end of the connecting rod engages with the adjusting hole.

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

[0011] Optionally, the locking shaft is provided with a pin hole, and the pin assembly cooperates with the pin hole.

[0012] Optionally, the device further includes a first support beam, which is fixedly connected to the door body and to the first positioning component.

[0013] Optionally, the device further includes a second support beam, which is fixedly connected to the door body and to the second positioning component.

[0014] Optionally, the second positioning component includes a pin seat, the two ends of which are respectively connected to the pin assembly and the second support beam.

[0015] Optionally, the measurement component includes a laser tracker.

[0016] A debugging method, the method comprising the following steps: Use the first positioning component to create positioning holes on the door body; Install the roller lock assembly onto the door, and then use the adjustment assembly to connect the two roller lock assemblies; The angle of the second positioning component on the second support beam is measured using the measuring component, and the second positioning component is fixed at the theoretical angle. Then, the pin assembly is fitted with the pin hole to fix the lock shaft at the theoretical angle.

[0017] Optionally, the step of installing the roller lock assembly onto the door body and connecting the two roller lock assemblies using the reuse adjustment assembly further includes the following steps: After aligning the positioning hole with the positioning guide hole, fix it in place.

[0018] This invention provides an aircraft boarding door debugging device and debugging method based on a roller lock. The device directly creates a positioning hole on the door body through a first positioning component. This hole, along with the pre-machined positioning guide hole of the roller lock component, forms a coordinating hole, converting theoretical coordinates into physical references. During operation, the positioning hole and the guide hole are mechanically aligned using pins or bolts, eliminating axial deviations caused by manual assembly. This ensures that the installation position of the roller lock component on the door body is consistent with the design theoretical value, thereby preventing misalignment between the load-bearing block and the lock shaft. Furthermore, 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 cooperation between the pin component and the lock shaft. This makes the angle adjustment process completely quantifiable, eliminates the uncertainty caused by subjective judgment, and solves the problem that the axis deviation of the roller lock is difficult to effectively reduce in the prior art. 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.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0026] It should be understood that in this application, all rotating, sliding, meshing and other moving parts are well lubricated and are provided with corresponding protective shells. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that each part in this application is made of metal or plastic material with adaptable strength in the relevant field to ensure that its structural rigidity meets the actual requirements.

[0027] To make the technical solutions in this invention clearer, the abbreviations or key terms involved in this invention are explained herein, wherein: Aircraft boarding doors are movable parts on the aircraft fuselage used for people to board and disembark. They can be opened, closed, locked, and unlocked by manual operation or a hydraulic system. The roller lock mechanism is a mechanism on aircraft boarding gates used for locking and unlocking the gates. It consists of roller lock components, adjustment components, load-bearing blocks, etc. The load-bearing block is a component installed on another aircraft structure. When the aircraft boarding door is locked, the load-bearing block contacts the locking shaft of the roller lock assembly, generating a force on the locking shaft in the opposite direction to the opening direction of the aircraft boarding door, thereby locking the aircraft boarding door.

[0028] Example 1: Please refer to the attached document as well. Figures 1 to 3 This embodiment provides an aircraft boarding door adjustment device based on a roller lock, the device comprising: A roller lock assembly 1 is installed on the door body 2 of the boarding gate. The roller lock assembly 1 has a locking shaft 4 inside and a positioning guide hole is provided on the roller lock assembly 1. Adjustment component 3, disposed on the roller lock assembly 1, is used to adjust the angle of the lock shaft 4; The first positioning component 5 is used to make a positioning hole on the door body 2 of the boarding gate; the positioning hole cooperates with the positioning guide hole to realize the positioning of the roller lock component 1 on the door body 2; The second positioning component 7 has a pin component 8 inside, which cooperates with the locking shaft 4 to fix the locking shaft 4 at a theoretical angle; wherein, the theoretical angle is the angle at which the locking shaft 4 together with the adjusting component 3 needs to be fixed. A 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 plan 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 manually positioned and installed on the boarding door body 2. The second stage is to verify the function by trial assembly of the cabin door, and to judge the uniformity of force on the roller lock mechanism by visual observation and tactile assessment. The third stage is to adjust the position of the load-bearing block according to the direction of the step difference deviation of the door body 2 to meet the step difference requirements based on previous debugging experience. The entire process requires repeated disassembly and assembly to verify the debugging effect.

[0030] During the aforementioned debugging process, errors in manual positioning caused deviations between the load-bearing block and the roller lock axis, which were difficult to eliminate. This affected the uniformity of force distribution on the roller lock mechanism and, in severe cases, could lead to the roller lock breaking, increasing unnecessary rework cycles and manufacturing costs. Debugging quality was overly dependent on the operator's experience and skill level, with significant differences in debugging results among different operators, making it impossible to guarantee debugging quality. Debugging efficiency was low, requiring multiple people to work together to debug a single hatch, and the debugging cycle was long, increasing labor and time costs.

[0031] Based on the above problems, this embodiment provides an aircraft boarding door debugging device based on a roller lock. The first positioning component 5 directly produces positioning holes on the door body 2. These holes cooperate with the pre-machined positioning guide holes of the roller lock component 1 to form a coordinating hole, converting the theoretical coordinates into physical references. During operation, the positioning holes and guide holes are mechanically aligned by pins or bolts, eliminating the axial deviation of manual assembly and 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 between the load-bearing block and the lock shaft 4.

[0032] Furthermore, the precise control of the angle of the locking 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 cooperation between the pin component 8 and the locking shaft 4. This makes the angle adjustment process completely quantified and eliminates the uncertainty caused by subjective judgment. It can be understood that the adjustment component 3 not only realizes the mechanical linkage between the two roller locking 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 component 3 includes a connecting rod, the locking shaft 4 is provided with an adjustment hole, and the end of the connecting rod cooperates with the adjustment hole.

[0034] It is understandable that the connecting rod is preferably attached. Figure 1In existing technologies, the adjustable linkage shown requires the operator to judge the angle of the locking shaft 4 by touch, which is not only inefficient but also results in significant differences in adjustment results among different personnel. This embodiment creatively transforms angle adjustment into a quantifiable mechanical movement by precisely machining an adjustment hole on the locking shaft 4 and forming a rigid connection with it. When the end of the linkage is inserted into the adjustment hole, its length change directly translates into a change in the rotation angle of the locking shaft 4. This mechanical transmission relationship makes the angle adjustment process predictable and repeatable.

[0035] In some embodiments, the connection between the connecting rod and the adjusting hole adopts a transition fit tolerance, which ensures the accuracy of transmission and avoids assembly difficulties caused by excessive tightness, thus achieving a balance between ease of operation and adjustment accuracy.

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

[0037] In some embodiments, the adjustment hole is formed on the upper end face of the locking shaft 4. In this embodiment, the free end of the connecting rod is also connected to the locking shaft 4 of another roller lock assembly 1. It is understood 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 makes it difficult to ensure the angular consistency of multiple locking shafts 4. This ultimately leads to uneven force distribution when the roller lock contacts the load-bearing block, severely affecting the airtightness and structural stability of the hatch. However, in this embodiment, by rigidly connecting the free end of the connecting rod to the locking shaft 4 of adjacent roller lock assemblies 1, multiple independent components are creatively integrated into a collaborative system. When the angle of one locking shaft 4 is adjusted, this change is directly transmitted to the adjacent locking shafts 4 through the connecting rod, achieving synchronous movement of multiple locking shafts 4. This effectively ensures that all roller lock assemblies 1 maintain the same rate of angular change during debugging, greatly minimizing the cumulative error caused by adjusting them individually.

[0038] In this embodiment, the locking shaft 4 is provided with a pin hole 10, and the pin assembly 8 cooperates with the pin hole 10. In traditional debugging methods, the angle of the locking shaft 4 mainly relies on the operator's feel and temporary fixation, which not only makes it difficult to guarantee 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 sealing performance and service life of the hatch. In this embodiment, by precisely machining the pin hole 10 on the locking shaft 4 and forming a tight fit with the pin assembly 8, the theoretical angle value is converted into a physical positioning reference. When the pin assembly 8 is inserted into the pin hole 10, the rotational freedom of the locking shaft 4 is completely restricted, ensuring that it always maintains the preset angle during operation. Compared with the original temporary fixation method, the technical solution in this embodiment reduces the problem of locking shaft 4 angle drift.

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

[0040] Understandably, in traditional debugging methods, positioning tools are often directly mounted on the door body 2 or a temporary support, making them highly susceptible to deformation of the door body 2 and external vibrations, leading to measurement reference drift and severely affecting debugging accuracy. Based on the above structure, by rigidly connecting the second support beam 9 to the door body 2, an independent and stable mounting platform is provided for the second positioning component 7. This separates the measurement reference system from the work object while maintaining a definite relative positional relationship, reducing the impact of tool vibration and door body 2 deformation on debugging accuracy. The second support beam 9 is made of high-strength alloy material, and its cross-sectional shape has been optimized to control its own weight while ensuring rigidity, thus avoiding additional load on the door body 2 and effectively suppressing 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 to the second positioning component 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 precision machined. Its cross-sectional shape has been optimized by finite element method, and it 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 by multiple high-strength bolts, a stable reference platform that is independent of the local deformation of the door body 2 is actually constructed. This makes the installation accuracy of the second positioning component 7 no longer affected by the welding deformation or assembly stress of the door body 2. Even when the door body 2 is subjected to load deformation, the support beam system can still maintain the stability of the measurement reference.

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

[0044] Based on the above structure, a short-path, high-rigidity connection system is established between the second support beam 9 and the pin assembly 8 by introducing a pin seat 11. During actual commissioning, technicians first fix the pin seat 11 to a preset position on the second support beam 9 using high-strength bolts. At this point, the reference surface of the pin seat 11 and the mounting surface of the support beam form a gapless fit. Then, a laser tracker is used to calibrate the orientation angle of the pin seat 11 to ensure precise parallelism with the theoretical axis. Finally, the pin assembly 8 is inserted into the tapered positioning hole of the pin seat 11 to achieve precise alignment. The entire installation process achieves precise angle transfer from the support beam reference to the working end of the pin. Compared to the original technology of directly mounting the pin on a simple bracket, the angle transfer accuracy is effectively improved.

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

[0046] Understandably, by using a laser tracker as the core measurement component and leveraging the principles of laser interferometry and a precision angle encoder, non-contact, high-precision measurement of the spatial attitude of the locking shaft 4 is achieved. Specifically, the laser tracker emits a laser beam to a reflective target ball mounted on the locking shaft 4, capturing the spatial position changes of the target ball in real time. Compared to traditional mechanical measurement methods, this improves accuracy by two orders of magnitude. 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 positioning holes on the door body 2; Install the roller lock assembly 1 onto the door body 2, and then use the adjustment assembly 3 to connect the two roller lock assemblies 1; The angle of the second positioning component 7 on the second support beam 9 is measured using the measuring component, and the second positioning component 7 is fixed at the theoretical angle. Then, the pin assembly 8 is fitted with the pin hole 10 to fix the locking shaft 4 at the theoretical angle.

[0048] It should be noted that the high-precision positioning holes created on the door body 2 by the first positioning component 5 solves the problem of large errors in the original manual marking positioning. The first positioning component 5 is made of a special alloy material, and its guide structure is precision machined to ensure that the dimensional and positional accuracy of the positioning holes is controlled within ±0.05mm. During the installation of the roller lock component 1, the design of the adjustment component 3 enables the two roller locks to achieve mechanical linkage, changing the inefficient mode of adjusting them individually. A laser tracker is used as an angle measuring tool to achieve non-contact, high-precision measurement of the angle of the second positioning component 7. In the final pin fixing stage, the precise fit design between 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 precision ground, with an extremely low clearance between it and the pin hole 10.

[0049] In this embodiment, Between the installation of the roller lock assembly 1 onto the door body 2 and the connection of the two roller lock assemblies 1 by the reuse adjustment assembly 3, the following steps are also included: After aligning the positioning hole with the positioning guide hole, fix it in place.

[0050] It should be noted that high-precision positioning holes are pre-fabricated on the door body 2, and matching positioning guide holes are machined on the roller lock assembly 1, thus constructing a mechanical coordinated positioning system. After the positioning holes and positioning guide holes are precisely aligned, positioning pins are used for fixing. The positioning holes are directly machined on the door body 2 using a CNC machine tool, and their positional accuracy is strictly calibrated by a laser tracker. The positioning guide holes are machined using precision fixtures during the manufacturing stage of the roller lock assembly 1 to ensure that the relative positional relationship with the functional structure of the assembly fully meets the design requirements.

[0051] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
