DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, the present invention provides a tail balancing device for a civil aircraft, comprising a top cover 1, a stabilizing block 2 is fixedly connected to the top of the top cover 1, a swinging member 3 is installed on the top cover 1 through the stabilizing block 2, and two slide rails 4 are arranged on the top of the swinging member 3, and a counterweight mechanism 5 and a clamping member 6 are respectively arranged at the bottom of the top cover 1; The counterweight mechanism 5 includes a rotating disk 51, a gear 52, a rack 53 and a fixed bin 54. The racks 53 are distributed in a circular array on the inner side wall of the rotating disk 51. The rotating disk 51 is meshed and connected with the gear 52 through the rack 53. The top surface of the fixed bin 54 is fixedly connected with the inner top wall of the rotating disk 51. The clamping member 6 includes a fixed rod 61 installed inside the fixed bin 54, a telescopic rod 62 arranged 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 distributed in a circular 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 one side of the top of the support block 65 is movably connected to a second connecting rod 66.

[0021] Adopting the above scheme: the design of the slide rail 4 provides more possibilities for the movement adjustment of the whole device. The slide groove on the top surface of the slide rail 4 and the internal slide groove, the adaptation relationship with the limit block 36 and the moving block 32, enable the swing member 3 to perform smooth linear motion on the slide rail 4. Through the fixation of bolts with the limit block 36 and the moving block 32, the position of the swing member 3 can be accurately adjusted according to the actual operation requirements, and it can remain stable after adjustment. This flexible adjustment method not only facilitates the switching of the device between different working positions, but also can effectively improve the accuracy of the operation when performing some operations that require high-precision positioning. The stabilizing block 2 set on the top of the top cover 1 and the connected swing member 3 not only provide a stable support foundation for the whole device, but also the special structural design of the swing member 3 enables it to be flexibly adjusted in different directions. The A-axis, B-axis and the related moving blocks 32, the swing member 3 The coordinated work of components such as the movable rod 37 enables the device to adapt to the space requirements of various working scenarios. It can effectively operate in a narrow space or in an environment requiring special angle operation, greatly improving the applicability and flexibility of the device. The setting of 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 accurately adjust the position and weight distribution of the counterweight according to actual needs. When the device performs various actions, the swing of the swing member 3 and the operation of the clamping member 6 and the stable center of gravity help prevent the device from tilting or shaking due to uneven force, thereby ensuring the balance of the tail of the civil aircraft.

[0022] like Figures 1 to 7 As shown, a driving 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, and 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, and a rotating shaft 7 is fixedly connected between the two stabilizing blocks 2. The swing member 3 includes an A-axis 31 located above the top cover 1, two moving blocks 32 fixedly connected to the two 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 bottom ends of the two swing rods 37 are rotatably connected to an adjusting block 38, and the bottom surface of the adjusting block 38 is fixedly connected to two short rods 39.

[0023] The above scheme is adopted: the clamping member 6 is composed 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 member 6 to accurately clamp objects of different shapes and sizes. The sliding connection mode of the telescopic rod 62 on the fixed rod 61 can automatically adjust the clamping range according to the size of the clamped object. With the linkage effect of the first connecting rod 64 and the second connecting rod 66, a uniform and stable clamping force can be applied to the object to avoid damage to the object during the clamping process. At the same time, the setting of the support block 65 further enhances the stability of the clamping, and its internal connection relationship with the clamping block 55 enables the clamping force to be better transmitted and dispersed, ensuring that even in a complex working environment, the clamping member 6 can firmly grasp the object, thereby improving the reliability of the operation. The A-axis 31 serves as the mounting support axis of the rotating sleeve 33 and the moving block 32, and bears the role of transmitting force and torque, so that the rotating sleeve 33 can The movable block 32 can perform stable rotational motion around it, and the movable block 32 can move on the slide rail 4 along the direction of the A-axis 31, 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 movable 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 in the sliding groove of the slide rail 4, and can provide a stable horizontal supporting force for the swing member 3 after being fixed, ensuring that the swing member 3 will not shift or shake in the horizontal direction when performing other actions, thereby improving the accuracy of the device operation. The rotating sleeve 33 connects the telescopic cylinder 34 with the A-axis 31, and converts 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 adjustment of the swing member 3 in the vertical plane is realized, so that the device can operate at different heights and inclination angles, thereby expanding the working space range of the device.

[0024] like Figures 2 to 6As shown, the inner walls of the two short rods 39 are rotatably connected to the two ends of the rotating shaft 7 respectively, the bottom surface of the telescopic cylinder 34 is fixedly connected with an auxiliary block, 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 slide grooves, and the slide grooves are provided with limit bolts. The insides of the two slide rails 4 are provided with sliding grooves adapted to the limit blocks 36 and the moving blocks 32, and the sliding grooves are used to assist the movement of the limit blocks 36 and the moving blocks 32. The two slide rails 4 are fixed to the limit blocks 36 and the moving blocks 32 by bolts, the top surface of the gear 52 is splined to the output end of the driving motor, and the gear 52 can be rotated by the drive of the driving motor, and the bottom surface of the rotating disk 51 is installed with a protective cover 511, and the protective cover 511 An inner cavity is provided for accommodating the clamping member 6, and a card slot is provided on the inner side wall of the fixed bin 54 in a circular array, and the fixed bin 54 is clamped with a card block 55 through the fixed bin 54, and one end of the card block 55 is fixedly connected to a counterweight block 8, the interior of the telescopic rod 62 is hollow, the fixed rod 61 is arranged on the inner wall of the telescopic rod 62, and the fixed rod 61 and the telescopic rod 62 are slidably connected, the bottom end of the fixed rod 61 passes through the telescopic rod 62 and is fixedly connected to the inner bottom wall of the cylinder 63, and 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, and one end of the second connecting rod 66 is rotatably connected to the outer wall of the top end of the telescopic rod 62, and the bottom end of the support block 65 is located inside the card block 55.

[0025] The above scheme is adopted: the first connecting rod 64 and the second connecting rod 66 constitute the connecting rod mechanism of the clamping member 6, one end of the first connecting rod 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, the support block 65 is driven to move in the vertical direction through its own swing, thereby realizing the initial clamping action of the object. The second connecting rod 66 connects the support block 65 and the outer wall of the top end of the telescopic rod 62, playing an auxiliary and restraining role. During the clamping process, it can automatically adjust the angle and force distribution between the connecting rods according to the shape and force conditions of the object, so that the clamping member 6 can better adapt to objects of different shapes and surface characteristics, improve the stability and reliability of clamping, and prevent the object from slipping or being damaged during the clamping process. The support block 65 is located at the bottom of the clamping mechanism, and its bottom end is located inside the clamping block 55. During the clamping process, the clamping force transmitted by the first connecting rod 64 can be effectively transmitted to the clamping block 55 and the counterweight block 8. The weight and stability of the counterweight block 8 further enhance the effect of the clamping force. At the same time, it can also ensure that the clamping force is evenly distributed in the entire device structure, prevent damage to the device due to excessive local force, and improve the overall stability and safety of the device during the clamping operation.

[0026] Working principle and use process of the present invention: Check whether the components of the device are firmly installed, including the connection between the top cover 1 and the stabilizing block 2, the connection between the components of the swinging member 3, the integrity of the counterweight mechanism 5 and the flexibility of the clamping member 6, etc., to ensure that the driving motor, telescopic cylinder 34 and other power components can operate normally, and that there is no looseness in the connection parts and no jamming in the movable joints. According to the work requirements, install the counterweight block 8 of appropriate weight and position in the card slot of the fixed bin 54, and prepare for the subsequent stable operation by adjusting the position of the card block 55 in the card slot, place the device in a suitable working position, and ensure that there are no obstacles in the surrounding environment, and there is enough space for the device to perform swinging, telescoping and other operations; When the swing member 3 is adjusted into place, the control mechanism of the clamping member 6 is started to make the telescopic rod 62 telescopically move 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 the connection point between it and the cylinder 63, thereby pushing the support block 65 to extend. At the same time, the second connecting rod 66 will also rotate with the movement of the support block 65, and since one end of the second connecting rod 66 is rotatably connected to the outer wall of the top end of the telescopic rod 62, it will have a certain constraint and auxiliary effect on the telescopic movement of the telescopic rod 62, so that the various connecting rods of the clamping member 6 work together, and the support block 65 is extended inside the clamping block 55 to achieve the limit of the counterweight block 8. According to the shape and size of the target object, the telescopic amount of the telescopic rod 62 can be flexibly adjusted to achieve accurate and stable clamping. According to the working target position, first adjust the position of the swing member 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, push the swing member 3 to move along the slide rail 4 to the approximate target position area, and then tighten the bolts to fix it on the slide rail 4. At this time, the position of the swing member 3 in the horizontal direction is preliminarily determined, and the telescopic cylinder 34 is started. 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 swing member 3 to swing at a certain angle with the rotating shaft 7 as the center. By controlling the telescopic stroke of the telescopic cylinder 34, the height and inclination angle of the swing member 3 in the vertical direction can be accurately adjusted, thereby adjusting the position of the counterweight block 8, and realizing the tail balancing function of the civil aircraft; The driving motor drives the gear 52 to rotate. Since the gear 52 is meshed 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 bin 54. The rotation direction and angle of the driving motor are precisely controlled to adjust the position of the rotating disk 51, thereby changing the distribution of the counterweight block 8 relative to other parts of the device and restoring the balance of the center of gravity of the device. During the rotation of the rotating disk 51, the rotating groove plays an auxiliary supporting and guiding role to ensure that the rotating disk 51 rotates smoothly. After the adjustment is completed, the driving motor is turned off. At this time, the counterweight mechanism 5 is in a new balanced state, providing a stable foundation for subsequent clamping and operation.
