[0038] The following is combined with Figure 1-3 This application is described in further detail.

[0039] The present application discloses an aircraft actuator disassembly device, referring to Figure 1 and Figure 2 The aircraft actuator disassembly device includes a shell 1, to which a clamping structure 2, a driving structure 3 and a propulsion structure 4 are connected. The driving structure 3 can drive the clamping structure 2 to clamp the to-be-disassembled part of the actuator threadedly connected, thereby separating the threaded connection structure of the actuator. At the same time, the actuator can be clamped by the clamping structure 2, and then the rod in the actuator can be pushed by the propulsion structure 4, so as to remove the rod, making the disassembly of the actuator more convenient.

[0040] Reference Figure 1 and Figure 2 The shell 1 is a long hollow shape, and includes a triangular portion that tapers at one end, and the triangular portion is provided with an opening that communicates with the inner cavity of the shell 1. The shell 1 includes a top cover 15 that can be removed by screws, and the top cover 15 can facilitate the installation of the structure inside the shell 1. The clamping structure 2 includes two clamping members 21, which are coaxially rotatably connected to the inner wall of the sharp corner of the shell 1, and one end of the two clamping members 21 is located outside the shell 1. The driving structure 3 can drive the ends of the two clamping members 21 located outside the shell 1 to rotate in a direction close to each other, thereby clamping the actuator.

[0041] Reference Figure 2 and Figure 3 The driving structure 3 includes a lifting rope 31 and a lifting member 32. One end of the lifting rope 31 is fixedly connected to one end of the clamping member 21 located in the housing 1, and the end of the lifting rope 31 away from the clamping member 21 is fixedly connected to the lifting member 32. Sliding holes 12 are provided on the opposite side walls of the housing 1. Both ends of the lifting member 32 are located in the sliding holes 12 and can slide in the sliding holes 12 in the direction of approaching and moving away from the clamping member 21. The housing 1 is provided with a through hole 11 whose penetration direction is perpendicular to and connected to the penetration direction of the sliding hole 12. The operator can pull the lifting member 32 to slide in the sliding hole 12 through the through hole 11, thereby driving the lifting rope 31. The lifting rope 31 pulls the two clamping members 21 to rotate, so that the clamping member 21 can clamp the parts to be disassembled that are threadedly connected to the actuator, which is convenient for unscrewing the threaded connection structure of the actuator, and reduces the difficulty of disassembling the actuator.

[0042] Reference Figure 2 and Figure 3 There are two rotating wheels 33 rotatably connected in the shell 1. The two rotating wheels 33 are located at one end of the shell 1 close to the clamping member 21 and between the ends of the two clamping members 21. A rotating groove 331 for the pulling rope 31 to pass through is opened on the outer wall of the rotating wheel 33. The rotating wheel 33 can adjust the direction in which the pulling rope 31 pulls the clamping member 21, so that it is more labor-saving to pull the pulling rope 31 through the pulling member 32 to drive the clamping member 21 to clamp.

[0043] A tension spring 23 is provided at one end of the clamping member 21 located in the shell 1, and one end of the tension spring 23 is fixedly connected to the side wall of the clamping member 21 away from the rotating wheel 33, and the end of the tension spring 23 away from the clamping member 21 is fixedly connected to the inner wall of the shell 1. When the lifting member 32 moves in the direction away from the clamping member 21, the tension spring 23 is stretched. When the lifting member 32 is released, the restoring force of the tension spring 23 allows the two clamping members 21 to rotate in the opposite direction, which is convenient for separating the actuator and the disassembly tool, and also convenient for placing the actuator between the clamping members 21, making the actuator disassembly device more convenient to use.

[0044] Reference Figure 1 and Figure 2 One end of the clamping member 21 located outside the housing 1 is rotatably connected to an extension section 22 parallel to the rotation axis of the clamping member 21. The extension section 22 can clamp the actuator cylinder as the clamping member 21 rotates. The extension section 22 is rotatably connected to the clamping member 21 so that the extension section 22 clamps the actuator cylinder more closely and more firmly, and at the same time, the extension section 22 can clamp actuator cylinders of different diameters.

[0045] The propulsion structure 4 includes a propulsion shaft 41, and a first fixing portion 13 and a second fixing portion 14 are fixedly connected on one side of the outer wall of the shell 1. The propulsion shaft 41 passes through the first fixing portion 13 and the second fixing portion 14, and the axis of the propulsion shaft 41 is located between the two extension sections 22. The propulsion shaft 41 is threadedly connected to the second fixing portion 14, and the end of the propulsion shaft 41 away from the extension section 22 is fixedly connected to the handle 42, and the end of the propulsion shaft 41 away from the handle 42 is fixedly connected to a plastic protrusion 43.

[0046] The first fixing portion 13 can support and guide the propulsion shaft 41; when the extension section 22 clamps the actuator, since the propulsion shaft 41 and the second fixing portion 14 are threadedly connected, the handle 42 can be turned to move the propulsion shaft 41 and press against the rod in the actuator, thereby pushing the rod out of the actuator body, making it easier to disassemble the actuator, and moving the propulsion shaft 41 by rotation can be more labor-saving, making the aircraft actuator disassembly device more convenient to use; the plastic protrusion 43 can reduce the friction between the propulsion shaft 41 and the actuator rod, making it easier to rotate the propulsion shaft 41 through the handle 42.

[0047] Reference Figure 1 and Figure 2 A first anti-skid pad 5 is fixedly connected to one side of the clamping member 21 that presses against the actuator, and a first groove 51 is provided on the first anti-skid pad 5; a second anti-skid pad 6 is fixedly connected to one side of the extension section 22 that presses against the actuator, and a second groove 61 is provided on the second anti-skid pad 6; the first anti-skid pad 5 and the first groove 51 can increase the friction between the clamping member 21 and the actuator, and the second anti-skid pad 6 and the second groove 61 can increase the friction between the extension section 22 and the actuator, so that the clamping member 21 and the extension section clamp the actuator more firmly.

[0048] The implementation principle of an aircraft actuator disassembly device according to an embodiment of the present application is as follows: when it is necessary to disassemble the threaded connection component of the actuator, the component to be disassembled is placed between the two first grooves 51, the lifting member 32 is tightened, the component to be disassembled that is threadedly connected to the actuator is clamped by the clamping member 21, and then the actuator disassembly device is rotated to unscrew the component to be disassembled; when it is necessary to remove the rod from the actuator, the actuator can be placed between the two second grooves 61, the lifting member 32 is tightened, the actuator is fixed, and then the handle 42 is rotated to move the propulsion shaft 41 along the axial direction, thereby pushing the rod in the actuator and pushing the rod out of the actuator. Through the aircraft actuator disassembly device, the threaded connection components of the actuator and the rod in the actuator are more convenient to disassemble, making it more convenient to disassemble the aircraft actuator.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
