AI Technical Summary
Existing technologies lack a dedicated platform for simulating in-situ maintenance of aircraft metal hydraulic ducts, causing the accuracy of duct maintenance to depend on the individual skills of the workers. This can easily lead to deviations in the spatial orientation of the ducts after repair, affecting maintenance quality and aircraft safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of aircraft maintenance tooling technology, specifically a simulated in-situ maintenance platform for aircraft metal hydraulic conduits. Background Technology
[0002] Aircraft metal hydraulic duct maintenance is a highly specialized and sophisticated task. Metal hydraulic ducts are fundamental components of the aircraft control system, and the hydraulic oil flowing within them controls the proper functioning of various control surfaces. The proper functioning of these ducts is crucial for safe aircraft operation. Aircraft metal hydraulic duct systems are made of materials such as aluminum alloy, titanium alloy, and stainless steel, and are widely distributed in areas such as the landing gear bay, wings, and cabin. The landing gear bay duct system is particularly complex, operating in the harshest environment, with closely spaced ducts serving different functions. After takeoff, hydraulic ducts may interfere with components such as pipe clamps, cable clamps, and check valves, or be damaged by sand or other foreign objects (FOD) during landing gear retraction and extension, leading to damage and deformation. Because the in-situ maintenance space in the landing gear bay is insufficient for accessing duct maintenance equipment, engineers must remove the metal hydraulic ducts to be repaired from the aircraft for off-site repair.
[0003] Currently, there is no platform in the domestic market specifically designed for simulating in-situ maintenance operations of aircraft metal hydraulic ducts. Therefore, the accuracy of duct maintenance is highly dependent on the worker's mental state and operational skills. If the operation is not performed well, the spatial orientation of the duct after repair may deviate, resulting in inconsistent quality of hydraulic duct maintenance. Summary of the Invention
[0004] The purpose of this invention is to provide a simulated in-situ maintenance platform for aircraft metal hydraulic conduits, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a simulated in-situ maintenance aircraft metal hydraulic conduit operation platform, including a horizontal operation platform, a vertical operation platform on the side of the horizontal operation platform, a cross slide rail assembly installed on the vertical operation platform, and a first suction cup type universal vise installed on the cross slide rail assembly.
[0006] The horizontal operating platform is equipped with a second suction cup type universal vise.
[0007] Preferably, the cross slide rail assembly includes two horizontal rails, two vertical rails, and a fixed platform. Each horizontal rail is provided with two first sliders, and each vertical rail is provided with two second sliders.
[0008] The ends of the two vertical rails are respectively inserted into the corresponding first sliders and locked, and the four corners of the first suction cup universal vise are fixed to the corresponding second sliders by locking bolts.
[0009] Preferably, the vertical operating table has multiple equally spaced mounting through holes, and the cross slide rail assembly is mounted on the through holes.
[0010] Preferably, the first suction cup type universal vise and the second suction cup type universal vise have the same structure, including a vacuum rubber suction cup, a base fixed on the vacuum rubber suction cup, a universal ball bearing and a universal ball bearing switch on the base, a detachable aluminum alloy sleeve above the universal ball bearing, a round hole jaw on the upper side of the aluminum alloy sleeve, a jaw adjustment switch on the round hole jaw, and a soft tube sleeve clamped inside the aluminum alloy sleeve.
[0011] Preferably, one side of the soft tube sleeve is cut vertically.
[0012] Preferably, the aluminum alloy sheath is provided with an anti-corrosion coating.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the utility model has a simple structure and novel design. The first suction cup universal vise is driven by the cross slide rail assembly to complete the fixation in any interval on the vertical operating table (Y-axis), thereby cooperating with the second suction cup universal vise fixed on the horizontal operating platform to fix aircraft metal hydraulic pipelines of various complex directions and lengths.
[0014] This aircraft metal hydraulic duct simulation in-situ maintenance operation platform is intuitive and easy to operate, greatly reducing the skill requirements of maintenance personnel for duct maintenance. It provides maintenance personnel with the best operating space, significantly reducing the probability of operational errors and avoiding the large economic losses caused by prolonged aircraft downtime due to substandard construction and the uncertainty brought to passenger travel.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 This utility model provides a technical solution: a simulated in-situ maintenance aircraft metal hydraulic conduit operation platform, including a horizontal operating platform 1, and a vertical operating platform 2 on the side of the horizontal operating platform 1, on which a cross slide rail assembly 3 is installed.
[0023] To meet the installation requirements of larger cross slide rails in the future, multiple equally spaced mounting through holes 21 can be opened on the table surface of the vertical operating table 2 to reserve sufficient space for future upgrades and modifications. Then, the cross slide rail assembly 3 can be installed on the mounting through holes 21 to achieve the connection and installation of the cross slide rail assembly 3 and the vertical operating table 2.
[0024] A first suction cup type universal vise 4 is set on the cross slide rail assembly 3 for one end of the metal hydraulic conduit;
[0025] A second suction cup type universal vise 5 is installed on the horizontal operating table 1 for the other end of the metal hydraulic conduit.
[0026] like Figure 2-4 As shown, in this embodiment, the cross slide rail assembly 3 includes two horizontal rails 31, two vertical rails 32, and a fixed platform 33.
[0027] Two first sliders 311 are slidably set on each horizontal track 31.
[0028] In addition, two second sliders 321 are also slidably disposed on each of the vertical tracks 32;
[0029] Insert the ends of the two vertical rails 32 into the corresponding first sliders 311 and lock them in place. Then fix the four corners of the fixed platform 33 to the corresponding second sliders 321 with locking bolts.
[0030] Finally, the first suction cup universal vise 4 is installed on the fixed platform 33.
[0031] like Figure 5 As shown, in this embodiment, the first suction cup type universal vise 4 and the second suction cup type universal vise 5 have the same structure, including a vacuum rubber suction cup 41, and a base 42 fixed on the vacuum rubber suction cup 41. The base 42 is provided with universal ball bearings 43 and universal ball bearing switches.
[0032] The removable aluminum alloy sleeve 45 is installed on top of the universal ball bearing 43 using hex bolts. The aluminum alloy sleeve 45 is made of 6061-T6 soft magnesium silicon aerospace aluminum alloy, and the surface of the aluminum alloy sleeve 45 is anodized to form a special anti-corrosion coating. In addition, six sets of 1 / 8, 2 / 8, 3 / 8, 4 / 8, 5 / 8 and 6 / 8 sizes of metal hydraulic lines can be made to fit the metal hydraulic lines.
[0033] A round hole jaw 451 is provided on the upper side of the aluminum alloy sheath 45 to facilitate clamping the soft tube sleeve 46. A jaw adjustment switch 452 is provided on the round hole jaw 451 to facilitate locking the soft tube sleeve 46 after clamping.
[0034] The aforementioned soft sleeve 46 is used to cover the metal hydraulic pipeline. By cutting one side vertically, it can completely cover the metal hydraulic pipeline. Thus, after the whole is inserted into the aluminum alloy sheath, it can prevent the metal hydraulic conduit from directly contacting the aluminum alloy sheath 45 and causing damage.
[0035] The flexible tubing sleeve 46 is also made in 6 sets according to different sizes of metal hydraulic lines;
[0036] The soft sleeve 46 is made of non-rigid metal materials such as PVC pipe and PP pipe. The use of such materials has a certain coefficient of friction, which can prevent the aluminum alloy fixing sleeve from directly contacting the metal hydraulic pipeline and causing damage to the outer wall of the conduit.
[0037] Working principle: First, install the cross slide rail assembly 3 onto the vertical operating table 2. Set two horizontal rails 31 vertically, ensuring an 80-centimeter gap between them. Then, use fixing bolts to pass through the mounting holes 21 on the vertical operating table 2 to fix the two horizontal rails 4. Finally, insert two first sliders 311 into each of the upper and lower horizontal rails 31.
[0038] Next, fix the four corners of the fixed platform 33 to the second slider 321 of the two vertical rails 32 with locking bolts. Then, insert the ends of the two vertical rails 32 into the fixing holes above the corresponding first slider 311 and lock the two vertical rails 32. At this time, the cross slide rail assembly is completed.
[0039] Select an aluminum alloy sleeve 45 of appropriate diameter and use hex bolts to secure it above the universal ball bearing 43 of the second suction cup type universal vise 5, applying enough force to prevent it from sliding freely.
[0040] Fully release the universal ball switch on the second suction cup type universal vise 5, fully release the jaw adjustment switch 452, and at this time the aluminum alloy sleeve 45 will be fully released.
[0041] Select a suitable diameter flexible tubing sleeve 46 and fit it onto the straight section of the metal hydraulic conduit to be repaired.
[0042] Insert the straight section of the metal hydraulic conduit with the soft sleeve 46 into the aluminum alloy sheath 45, tighten the jaw adjustment switch 452, and then gently fasten the vacuum rubber suction cup 41 of the second suction cup universal vise 5 onto the horizontal operating table 1.
[0043] Securely lock the vacuum rubber suction cup 41 of the first suction cup type universal vise 4 onto the cross slide rail assembly. Select an aluminum alloy sleeve 12 of appropriate diameter and use hex bolts to fix it above the universal ball bearing 43 of the first suction cup type universal vise 4. Apply enough force to prevent it from sliding freely.
[0044] Fully release the universal ball switch on the first suction cup type universal vise 4, fully release the jaw adjustment switch 452, and at this time the aluminum alloy sleeve 45 will be fully released.
[0045] Select a suitable diameter flexible tubing sleeve 46 and fit the flexible tubing sleeve 46 onto the other straight section of the metal hydraulic conduit to be repaired.
[0046] Insert the other straight section of the metal hydraulic conduit, which is fitted with a soft sleeve 46, into the aluminum alloy sheath 45, and then tighten the jaw adjustment switch 452.
[0047] Adjust the universal ball switch of the first suction cup type universal vise 4 so that the metal hydraulic tube does not bear torque and the two ends are naturally fixed.
[0048] At this point, the jaw adjustment switch 452 of the first suction cup universal vise 4 is fully locked. Then, the vacuum rubber suction cup 41 of the second suction cup universal vise 5 is firmly locked onto the horizontal operating table 1, and the jaw adjustment switch 452 of the second suction cup universal vise 5 is also fully locked. Thus, the in-situ simulation of the metal hydraulic conduit to be repaired is completed. Then, the repair work of the aircraft metal hydraulic conduit is completed according to the requirements of the aircraft maintenance manual.
[0049] During disassembly, fully loosen the jaw adjustment switches 452 of both the first suction cup type universal vise 4 and the second suction cup type universal vise 5.
[0050] Then, unscrew the Allen bolts on the first suction cup universal vise 4 and the second suction cup universal vise 5 to remove the metal hydraulic conduit along with the aluminum alloy sheath 45 and the soft sheath 46.
[0051] Subsequently, the aluminum alloy sheath 45 and the soft sheath 46 were removed, and the simulated in-situ repair of the aircraft's metal hydraulic conduit was completed.
[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
