Description

Technical Field

[0001] This utility model relates to the field of actuator testing technology, and in particular to a reverse-push actuator repair device. Background Technology

[0002] Thrust reversers can generate thrust in the opposite direction to the aircraft's flight direction, so their function is opposite to that of the engine. Most of the bushings of existing thrust reversers are screw-in type, and after assembly, they are located inside the actuator cylinder. There is no external force point, so it is not easy to disassemble and assemble them.

[0003] Although existing technologies have tooling for disassembling and assembling reverse actuator bushings, such as the solution disclosed in the utility model patent with authorization announcement number CN223084633U, this solution requires relatively cumbersome operations to align the four plugs with the four process holes when actually fitting the four process holes reserved on the actuator bushing. After alignment, the tooling also needs to be manually locked before a special wrench can be connected for operation, which is too inconvenient in actual use.

[0004] Therefore, it is necessary to invent a reverse-push actuator maintenance device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a reverse thrust actuator maintenance device with a simple structure. It can be adjusted, limited, and driven directly by an electric hex wrench. After disassembly and assembly, the utility model can be removed from the actuator bushing by simply removing the electric hex wrench. This makes it more convenient to use in practice. It solves the problem mentioned in the background art that the existing solution requires a relatively cumbersome operation to align the four plugs with the four process holes when actually matching them with the four process holes on the actuator bushing. After alignment, the tooling also needs to be manually locked before connecting the special wrench for operation, which is too inconvenient in actual use.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a thrust reverser maintenance device, comprising: A pre-drilled hole insertion mechanism, wherein the pre-drilled hole insertion mechanism is used to insert into four pre-drilled process holes on the actuator bushing and drive the actuator bushing to rotate; and An electric wrench connection mechanism includes a rotating seat that fits against the top of a mounting base. A connecting groove is provided at the center of the bottom of the rotating seat. A connecting post fixedly installed at the center of the top of the mounting base is rotatably mounted on the inner side of the connecting groove via a bearing. Four evenly distributed inclined push grooves are provided on the outer side of the top of the rotating seat. The inner wall of any one of the inclined push grooves slides against the adjacent insert rod. A hexagonal groove for connecting to an electric hexagonal wrench is provided at the center of the top of the rotating seat.

[0007] According to at least one embodiment of the thrust reverser maintenance device of the present disclosure, the pre-drilled hole insertion mechanism includes a mounting base, the top outer side of which is provided with four guide grooves, and a guide rod is fixedly provided on the inner side of any one of the guide grooves in the horizontal direction.

[0008] According to at least one embodiment of the reverse thrust actuator maintenance device of this disclosure, an insert rod is slidably sleeved on the outer side of any one of the guide rods, and the outer wall of the insert rod is slidably attached to the inner wall of the adjacent guide groove.

[0009] According to at least one embodiment of the present disclosure, a thrust reverser maintenance device has a clearance hole at the bottom of the mounting base, and a rubber pad is bonded to the inner side of the clearance hole.

[0010] The technical effects and advantages of this utility model are as follows: This utility model has a simple structure and can be adjusted, limited, and driven directly by an electric hex wrench. After disassembly and assembly, the utility model can be removed from the actuator bushing by simply removing the electric hex wrench, making it more convenient in actual use.

[0016] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., as in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0017] Figure 1 This is a schematic diagram of the overall structure of a reverse actuator maintenance device according to one embodiment of the present disclosure.

[0018] Figure 2 This is a schematic diagram of the reserved hole insertion mechanism 1 of a reverse thrust actuator maintenance device according to one embodiment of the present disclosure.

[0019] Figure 3 This is a schematic diagram of the electric wrench connection mechanism 2 of a reverse actuator maintenance device according to one embodiment of the present disclosure.

[0020] like Figures 1-3 As shown, the thrust reverser maintenance device disclosed herein is applicable to the disassembly and assembly of aircraft thrust reverser bushings (screw-in type, assembled inside the actuator cylinder and without external force points), solving the problem of cumbersome alignment and manual locking required by existing tooling. Specifically, it includes components such as a pre-drilled hole insertion mechanism 1 and an electric wrench connection mechanism 2.

[0021] like Figure 2 As shown in this disclosure, the pre-drilled hole insertion mechanism 1 includes a mounting base 11, which is generally disc-shaped and made of aerospace-grade aluminum alloy, which is lightweight and high-strength. Four guide grooves 12 are provided on the outer side of the top of the mounting base 11. A guide rod 13 is fixedly provided on the inner side of any one of the guide grooves 12 in the horizontal direction. The guide rod is cylindrical and made of 304 stainless steel, which is rust-proof, wear-resistant, and has stable rigidity. An insertion rod 14 is slidably sleeved on the outer side of any one of the guide rods 13. The insertion rod 14 is cylindrical and made of 40Cr alloy structural steel, which is high-strength, deformation-resistant, and wear-resistant. The outer wall of the insertion rod 14 slides against the inner wall of the adjacent guide groove 12. An avoidance hole 15 is provided at the bottom of the mounting base 11, and a rubber pad 16 is bonded to the inner side of the avoidance hole 15.

[0022] like Figure 3As shown, in a preferred embodiment, the electric wrench connecting mechanism 2 includes a rotating seat 21 that fits against the top of the mounting base 11. It is also a disc-shaped structure made of high-strength aluminum alloy, which can bear high torque while being lightweight. A connecting groove 22 is provided at the bottom center of the rotating seat 21. A connecting column 23, which is fixedly set at the top center of the mounting base 11, is provided on the inner side of the connecting groove 22 through a bearing. It is a cylindrical structure made of high-quality carbon structural steel, which can ensure high-strength support and firm assembly. Four evenly distributed inclined push grooves 24 are provided on the outer side of the top of the rotating seat 21. The inner wall of any inclined push groove 24 slides against the adjacent plug rod 14. A hexagonal groove 25 for connecting with an electric hexagonal wrench is provided at the top center of the rotating seat 21.

[0023] By setting the aforementioned pre-drilled hole insertion mechanism 1 and electric wrench connection mechanism 2, the electric hexagonal wrench can be inserted into the hexagonal slot 25 to achieve connection. Then, the bottom ends of the four insertion rods 14 are attached to the surface of the actuator bushing. At this time, the electric hexagonal wrench drives the rotating seat 21 to rotate around the connecting column 23 through the hexagonal slot 25. When the rotating seat 21 rotates, it drives the four inclined push grooves 24 to rotate synchronously. When the inclined push grooves 24 rotate, they push the adjacent insertion rods 14 through the inner wall, thereby causing the insertion rods 14 to move inward or outward along the guide rod 13 inside the guide groove 12. During the inward or outward movement of the four insertion rods 14, they gradually align with the four pre-drilled holes. After complete alignment, the four insertion rods are then inserted into the four pre-drilled holes. The rod 14 is inserted into the four pre-drilled holes. Then, the electric hex wrench drives the rotating seat 21 to rotate around the connecting column 23 via the hexagonal slot 25. At this time, the four rods 14 cannot move further due to the limitation of the pre-drilled holes. The rotating seat 21 then directly drives the mounting seat 11 and the four rods 14 to rotate, thereby causing the four rods 14 to drive the actuator bushing to rotate. Finally, the actuator bushing is disassembled or assembled. Compared with the prior art, the structure is simple and can be directly adjusted, limited, and driven by the electric hex wrench. After disassembly and assembly, the utility model can be removed from the actuator bushing by simply removing the electric hex wrench. It is more convenient in actual use.

[0024] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0025] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
