Description

Technical Field

[0001] This invention belongs to the field of civil aircraft technology, specifically a tail balancing device for civil aircraft. Background Technology

[0002] The balancing device at the tail of a civil aircraft mainly refers to the tail fin, which is a device installed at the tail of the aircraft to enhance flight stability. Most tail fins include a horizontal tail (horizontal tail) and a vertical tail (vertical tail), while a few use a V-tail.

[0003] Existing civil aircraft tail balancing devices typically rely on a single power source and fixed structure to adjust the tail. These devices are less flexible in complex working environments, such as confined spaces and situations requiring precise angle adjustments, and often struggle to maintain a stable operating attitude. Furthermore, the stability of the equipment itself is crucial for ensuring the safety of the aircraft's tail structure during operation. Due to the high precision requirements of aircraft components, if the equipment tilts or wobbles due to an unstable center of gravity, it could potentially cause collision damage to the aircraft's tail, affecting the aircraft's structural integrity and flight safety. Previous equipment designs were not precise or flexible enough in their weight distribution, making it difficult to maintain a stable center of gravity under various complex operating maneuvers and failing to meet the stringent stability requirements for civil aircraft tail operations.

[0014] Preferably, the top surface of the gear is splinedly connected to the output end of the drive motor, and the gear can rotate by the drive motor. The bottom surface of the rotating disk is equipped with a protective cover, and the protective cover has an inner cavity for accommodating the clamping parts.

[0015] Preferably, the inner sidewall of the fixed chamber is provided with slots in a circular array, and the fixed chamber is connected to a locking block, one end of which is fixedly connected to a counterweight.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention, through the stabilizing block and connected swinging component on the top of the cover, not only provides a stable support foundation for the entire device, but also the special structural design of the swinging component allows for flexible movement adjustment in different directions. The coordinated work of the A-axis, B-axis, and related moving blocks, swing rods, and other components enables the device to adapt to the spatial requirements of various working scenarios. Whether in narrow spaces or environments requiring special angle operations, it can effectively perform operations, greatly improving the applicability and flexibility of the device. The counterweight mechanism effectively balances the center of gravity of the device, and the meshing connection between the rotating disk and the gears allows for precise adjustment of the position and weight distribution of the counterweight according to actual needs. When the device performs various actions, the swinging of the swinging component and the operation of the clamping component, along with the stable center of gravity, help prevent the device from tilting or swaying due to uneven force, ensuring the balance of the tail of the civil aircraft.

[0019] The clamping component of this invention consists of a fixed rod, a telescopic rod, a cylinder, a first connecting rod, and a second connecting rod. This structure enables the clamping component to accurately clamp objects of different shapes and sizes. The sliding connection of the telescopic rod to the fixed rod allows for automatic adjustment of the clamping range according to the size of the object being clamped. Combined with the linkage of the first and second connecting rods, a uniform and stable clamping force can be applied to the object, preventing damage during clamping. At the same time, the support block further enhances the stability of the clamping, and its internal connection with the locking block allows for better transmission and distribution of the clamping force, ensuring that the clamping component can firmly grasp the object even in complex working environments, thus improving the reliability of the operation.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 7 As shown, the present invention provides a tail balancing device for a civil aircraft, including a top cover 1, a stabilizing block 2 fixedly connected to the top of the top cover 1, a swinging member 3 installed on the top cover 1 through the stabilizing block 2, and two slide rails 4 provided on the top of the swinging member 3, and a counterweight mechanism 5 and a clamping member 6 respectively provided on the bottom of the top cover 1.

[0030] The counterweight mechanism 5 includes a rotating disk 51, a gear 52, a rack 53, and a fixed chamber 54. The rack 53 is arranged in a circumferential array on the inner side wall of the rotating disk 51. The rotating disk 51 is connected to the gear 52 through the rack 53. The top surface of the fixed chamber 54 is fixedly connected to the inner top wall of the rotating disk 51.

[0031] The clamping component 6 includes a fixed rod 61 installed inside the fixed chamber 54, a telescopic rod 62 disposed on the outer wall of the fixed rod 61, a cylinder 63 installed at one end of the telescopic rod 62, and a first connecting rod 64 arranged in a circumferential array on the outer surface of the cylinder 63. One end of the first connecting rod 64 is movably connected to a support block 65, and a second connecting rod 66 is movably connected to one side of the top of the support block 65.

[0032] The above-mentioned design of the slide rail 4 provides more possibilities for the motion adjustment of the entire device. The sliding groove on the top surface of the slide rail 4 and its internal sliding groove, along with the matching relationship between the limiting block 36 and the moving block 32, allow the swinging component 3 to perform smooth linear motion on the slide rail 4. By fixing the swinging component 3 to the limiting block 36 and the moving block 32 with bolts, the position of the swinging component 3 can be precisely adjusted according to actual operational needs and can remain stable after adjustment. This flexible adjustment method not only facilitates switching between different working positions of the device but also effectively improves the accuracy of operation when performing tasks requiring high-precision positioning. The stabilizing block 2 on the top of the top cover 1 and the connected swinging component 3 not only provide a stable support foundation for the entire device but also, due to the special structural design of the swinging component 3, allows for flexible motion adjustment in different directions. The A-axis, B-axis, and related moving blocks 32 and swinging components... The coordinated operation of components such as the lever 37 enables the device to adapt to the spatial requirements of various working scenarios. It can effectively operate in narrow spaces or environments requiring special angle operation, greatly improving the applicability and flexibility of the device. The counterweight mechanism 5 effectively balances the center of gravity of the device. The meshing connection between the rotating disk 51 and the gear 52 can precisely adjust the position and weight distribution of the counterweight according to actual needs. When the device performs various actions, the swing of the swinging component 3 and the operation of the clamping component 6 help prevent the device from tilting or shaking due to uneven force, ensuring the balance of the tail of the civil aircraft.

[0033] like Figures 1 to 7 As shown, a drive motor is fixedly installed on the top of the top cover 1, and a rotating groove adapted to the rotating disk 51 is opened inside the top cover 1. The rotating groove is set to assist the rotation of the rotating disk 51. There are two stabilizing blocks 2, which are symmetrically distributed on the top surface of the top cover 1. A rotating shaft 7 is fixedly connected between the two stabilizing blocks 2. The swinging component 3 includes an A-axis 31 located above the top cover 1, two moving blocks 32 fixedly connected to both ends of the A-axis 31, a rotating sleeve 33 installed on the outer wall of the A-axis 31, and a telescopic cylinder 34 fixedly connected to the bottom surface of the rotating sleeve 33. The swinging component 3 also includes a B-axis 35 located on one side of the A-axis 31, a limiting block 36 fixedly connected to both ends of the B-axis 35, and two swing rods 37 rotatably connected to the outer wall of the limiting block 36. An adjusting block 38 is rotatably connected to the bottom end of each of the two swing rods 37. Two short rods 39 are fixedly connected to the bottom surface of the adjusting block 38.

[0034] The above-mentioned solution is adopted: the clamping component 6 consists of a fixed rod 61, a telescopic rod 62, a cylinder 63, a first connecting rod 64, and a second connecting rod 66. This structure enables the clamping component 6 to accurately clamp objects of different shapes and sizes. The sliding connection of the telescopic rod 62 to the fixed rod 61 allows for automatic adjustment of the clamping range according to the size of the object being clamped. Combined with the linkage of the first connecting rod 64 and the second connecting rod 66, a uniform and stable clamping force can be applied to the object, preventing damage during clamping. Simultaneously, the support block 65 further enhances the stability of the clamping. Its internal connection with the locking block 55 allows for better transmission and dispersion of the clamping force, ensuring that the clamping component 6 can firmly grasp the object even in complex working environments, improving operational reliability. The A-axis 31, as the mounting support shaft for the rotating sleeve 33 and the moving block 32, bears the responsibility of transmitting force and torque, enabling the rotating sleeve 33 to... The device can rotate stably around the slide rail 4, while the moving block 32 can move along the A-axis 31 on the slide rail 4, thereby realizing the compound motion adjustment of the swing member 3 in the horizontal and vertical directions to adapt to the working requirements of different positions and angles. The moving block 32 cooperates with the slide rail 4 and can accurately adjust the position of the swing member 3 in the horizontal direction by moving within the sliding groove of the slide rail 4. After being fixed, it can provide stable horizontal support force for the swing member 3, ensuring that the swing member 3 will not deviate or shake in the horizontal direction when performing other actions, thus improving the accuracy of the device operation. The rotating sleeve 33 connects the telescopic cylinder 34 to the A-axis 31, converting the linear motion of the telescopic cylinder 34 into rotational motion around the A-axis 31. By changing the telescopic length of the telescopic cylinder 34, the angle of the swing member 3 in the vertical plane can be adjusted, enabling the device to operate at different heights and tilt angles, thus expanding the working space range of the device.

[0035] like Figures 2 to 6As shown, the inner walls of the two short rods 39 are rotatably connected to both ends of the rotating shaft 7, respectively. An auxiliary block is fixedly connected to the bottom surface of the telescopic cylinder 34, and the inner wall of the auxiliary block is rotatably connected to the outer wall of the rotating shaft 7. The top surfaces of the two slide rails 4 are provided with sliding grooves, and the sliding grooves are provided with limiting bolts. The interiors of the two slide rails 4 are provided with sliding grooves that are compatible with the limiting block 36 and the moving block 32, and the sliding grooves are used to assist the movement of the limiting block 36 and the moving block 32. The two slide rails 4 are fixed to the limiting block 36 and the moving block 32 by bolts. The top surface of the gear 52 is splinedly connected to the output end of the drive motor. The gear 52 can rotate by the drive motor. A protective cover 511 is installed on the bottom surface of the rotating disk 51, and the protective cover 511... An inner cavity is provided to accommodate the clamping component 6. The inner sidewall of the fixing chamber 54 is provided with slots arranged in a circular array. The fixing chamber 54 is connected to a locking block 55. One end of the locking block 55 is fixedly connected to a counterweight block 8. The telescopic rod 62 is hollow inside. The fixing rod 61 is set on the inner wall of the telescopic rod 62 and is slidably connected to the telescopic rod 62. The bottom end of the fixing rod 61 passes through the telescopic rod 62 and is fixedly connected to the inner bottom wall of the cylinder 63. The bottom surface of the telescopic rod 62 is also connected to the inner bottom wall of the cylinder 63. The other end of the first connecting rod 64 is movably connected to the outer surface of the cylinder 63. One end of the second connecting rod 66 is rotatably connected to the outer wall of the top end of the telescopic rod 62. The bottom end of the support block 65 is located inside the locking block 55.

[0036] The above scheme is adopted: the first link 64 and the second link 66 form the linkage mechanism of the clamping member 6. One end of the first link 64 is movably connected to the outer surface of the cylinder 63, and the other end is connected to the support block 65. When the cylinder 63 moves, it drives the support block 65 to move in the vertical direction through its own swing, so as to realize the initial clamping action of the object. The second link 66 connects the support block 65 to the outer wall of the top of the telescopic rod 62, playing an auxiliary and constraining role. During the clamping process, it can automatically adjust the angle and force distribution between the links according to the shape of the object and the force conditions, so that the clamping component 6 can better adapt to objects with different shapes and surface characteristics, improve the stability and reliability of clamping, and prevent the object from slipping or being damaged during clamping. The support block 65 is located at the bottom of the clamping mechanism, and its bottom end is located inside the locking block 55. During the clamping process, it can effectively transfer the clamping force transmitted from the first link 64 to the locking block 55 and the counterweight 8. With the help of the weight and stability of the counterweight 8, the effect of the clamping force is further enhanced. At the same time, it can also ensure the uniform distribution of the clamping force in the entire device structure, prevent the device from being damaged due to excessive local force, and improve the overall stability and safety of the device during clamping operation.

[0037] The working principle and usage process of this invention: Check whether each component of the device is installed firmly, including the connection between the top cover 1 and the stabilizing block 2, the connection between each component of the swinging part 3, the integrity of the counterweight mechanism 5, and the flexibility of the clamping part 6, etc., to ensure that the power components such as the drive motor and the telescopic cylinder 34 can operate normally, and that there is no looseness in each connection part and no jamming in each moving joint. According to the work requirements, install a counterweight block 8 of appropriate weight and position in the slot of the fixed chamber 54. By adjusting the position of the card block 55 in the slot, prepare for subsequent stable operation. Place the device in a suitable working position and ensure that there are no obstacles in its surrounding environment and that there is enough space for the device to swing, telescopic and other actions.

[0038] Once the swinging component 3 is adjusted to the correct position, the control mechanism of the clamping component 6 is activated, causing the telescopic rod 62 to extend and retract on the fixed rod 61. Since one end of the first connecting rod 64 is movably connected to the outer surface of the cylinder 63, when the telescopic rod 62 moves, the first connecting rod 64 will rotate around its connection point with the cylinder 63, thereby pushing the support block 65 to extend. At the same time, the second connecting rod 66 will also rotate as the support block 65 moves. Since one end of the second connecting rod 66 is rotatably connected to the outer wall of the top of the telescopic rod 62, it will exert a certain constraint and assistance on the telescopic movement of the telescopic rod 62, so that the various connecting rods of the clamping component 6 work together. The support block 65 extends inside the locking block 55 to achieve the limiting of the counterweight block 8. According to the shape and size of the target object, the extension and retraction of the telescopic rod 62 can be flexibly adjusted to achieve precise and stable clamping.

[0039] According to the target position, first adjust the position of the swinging component 3 on the slide rail 4, loosen the bolts connecting the slide rail 4 with the limit block 36 and the moving block 32, so that the limit block 36 and the moving block 32 can move freely in the sliding groove. After pushing the swinging component 3 along the slide rail 4 to the approximate target position area, tighten the bolts to fix it on the slide rail 4. At this time, the position of the swinging component 3 in the horizontal direction is initially determined. Start the telescopic cylinder 34. The telescopic movement of the telescopic cylinder 34 drives the rotating sleeve 33 to move up and down along the A axis. Since the auxiliary block on the bottom surface of the rotating sleeve 33 is connected to the short rod 39 through the rotating shaft 7, it drives the entire swinging component 3 to swing at a certain angle around the rotating shaft 7. By controlling the telescopic stroke of the telescopic cylinder 34, the height and tilt angle of the swinging component 3 in the vertical direction can be precisely adjusted, thereby adjusting the position of the counterweight 8 and realizing the balancing function of the tail of the civil aircraft.

[0040] The drive motor drives the gear 52 to rotate. Since the gear 52 meshes with the rack 53 on the inner wall of the rotating disk 51, the rotating disk 51 rotates on the top surface of the fixed chamber 54. By precisely controlling the rotation direction and angle of the drive motor, the position of the rotating disk 51 is adjusted, thereby changing the distribution of the counterweight 8 relative to other parts of the device and restoring the balance of the device's center of gravity. During the rotation of the rotating disk 51, the rotating groove plays an auxiliary support and guiding role to ensure that the rotating disk 51 rotates smoothly. After the adjustment is completed, the drive motor is turned off. At this time, the counterweight mechanism 5 is in a new equilibrium state, providing a stable foundation for subsequent clamping and operation.
