Technical Field

[0001] This utility model relates to the field of aircraft engine end journal disassembly and assembly technology, and in particular to a quick disassembly and assembly tool for aircraft engine end journals. Background Technology

[0002] Aircraft engines are secured to the aircraft's load-bearing frame via two end journals, one on the inner side and one on the outer side. Disassembling and assembling the engine requires first removing and installing these end journals. Traditional methods involve tightening and loosening the end journals with a wrench. However, because the clearance between the engine end journal and the bearing is small and the fit is tight, it's not easy to easily remove or install the end journal. Especially during installation, it's necessary not only to insert the end journal into the bearing but also to repeatedly rotate and adjust it to ensure the alignment of the fixing bolt holes.

[0003] Due to the limited assembly space and the tight fit between the end journal and the bearing, traditional wrenches are inefficient during operation. Therefore, there is a need to design an efficient and easy-to-use tool for quick assembly and disassembly of engine end journals. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A quick disassembly and assembly tool for aircraft engine end journals includes a fixed connector 1, a disassembly and assembly handle 2, and an assistive component 3. One end of the disassembly and assembly handle 2 is threadedly connected to the fixed connector 1, and the assistive component 3 is slidably mounted on the outer wall of the disassembly and assembly handle 2.

[0023] As a technical optimization of this utility model, the outer wall of the fixed connector 1 is provided with a threaded connection part 4, which is used to connect with the engine end journal by thread. The outer wall of the fixed connector 1 near the disassembly handle 2 is provided with a first limiting part 5, and the outer wall of the first limiting part 5 near the disassembly handle 2 has multiple grooves 11. The threaded connection part 4 on the fixed connector 1 can be threadedly connected and fixed with the threaded hole at the tail of the engine end journal during actual use; the first limiting part 5 is used to limit the stroke of the assist component 3 on the disassembly handle 2, and at the same time transmit the disassembly force from the assist component 3; when the threaded connection part 4 needs to be removed from the end journal alone, a specially made wrench that is adapted to the multiple grooves 11 can be used. After the end of the wrench is inserted and adapted to the multiple grooves 11 on the outer wall of the first limiting part 5, the fixed connector 1 can be loosened by rotating the wrench, so as to facilitate the disassembly of the fixed connector 1 under certain circumstances.

[0024] As a technical optimization of this utility model, the fixed connector 1 has a connecting hole 6 inside at one end near the disassembly handle 2, and a threaded connector 7 that matches the connecting hole 6 is installed at one end of the disassembly handle 2. The connecting hole 6 inside the fixed connector 1 is threadedly connected to the threaded connector 7 at one end of the disassembly handle 2, which facilitates flexible disassembly and assembly of the fixed connector 1.

[0025] As a technical optimization of this utility model, the assist component 3 has a through hole 10 inside, and the assist component 3 is slidably connected to the outer wall of the disassembly handle 2 through the through hole 10. The through hole 10 inside the assist component 3 allows the assist component 3 to be fitted onto the surface of the disassembly handle 2 after the fixing connector 1 is detached from one end of the disassembly handle 2.

[0026] As a technical optimization of this utility model, a rubber sleeve is adhered to the outer wall of the assistive component 3, and the outer wall of the rubber sleeve is provided with a rough surface. Adhering the rubber sleeve to the outer wall of the assistive component 3 makes it convenient for manual gripping of the assistive component 3, and the rough surface on the outer wall of the rubber sleeve can improve the friction when manually gripping the assistive component 3.

[0027] As a technical optimization of this utility model, a second limiting part 8 is installed on the outer wall of the end of the disassembly handle 2 away from the fixed joint 1, and the assisting component 3 is located between the first limiting part 5 and the second limiting part 8. A handle 9 is installed on the end of the disassembly handle 2 away from the fixed joint 1. After the assisting component 3 is installed on the surface of the disassembly handle 2, the fixed joint 1 is connected to the threaded joint 7 at one end of the disassembly handle 2 through the internal connecting hole 6. This allows the two ends of the assisting component 3 located on the surface of the disassembly handle 2 to be limited by the first limiting part 5 on the fixed joint 1 and the second limiting part 8 on the disassembly handle 2, preventing the assisting component 3 from sliding down and falling off the surface of the disassembly handle 2.

[0028] In this utility model, the fixing connector 1 is first unscrewed from one end of the disassembly handle 2, and the assisting component 3 is slidably fitted onto the surface of the disassembly handle 2. Then, the fixing connector 1 is threadedly connected to the threaded connector 7 at one end of the disassembly handle 2 through the internal connecting hole 6, so that the two ends of the assisting component 3 located on the surface of the disassembly handle 2 can be limited by the first limiting part 5 on the fixing connector 1 and the second limiting part 8 on the disassembly handle 2.

[0029] Then, connect and fix the threaded connection part 4 of the fixed connector 1 to the threaded hole of the engine end journal. Using a quick-release tool for aircraft engine end journals, place the end journal into the engine bearing. Figure 1 As shown, after manually gripping the assist component 3, it slides back and forth along the surface of the disassembly handle 2, causing both ends of the assist component 3 to impact the first limiting part 5 and the second limiting part 8 respectively. During the back-and-forth movement of the assist component 3 on the surface of the disassembly handle 2, it can apply installation or disassembly force to the end journal. That is, when manually driving the assist component 3 to impact the first limiting part 5, the first limiting part 5 bears and transmits the impact force from the assist component 3, allowing the end journal to enter the installation part along the direction of the disassembly handle 2. When manually driving the assist component 3 to impact the second limiting part 8, the second limiting part 8 bears and transmits the impact force from the assist component 3, allowing the end journal to slowly move outward from the installation part along the direction of the disassembly handle 2. Thus, by using the back-and-forth movement of the assist component 3 on the surface of the disassembly handle 2, the end journal is driven to move forward and backward along the direction of the disassembly handle 2.

[0030] Meanwhile, when it is necessary to adjust the angle of the end journal, the operator can hold the handle 9 with one hand and hold the assist component 3 with the other hand and keep it still. While manually driving the handle 9 to rotate, the disassembly handle 2 and the fixing joint 1 will rotate together, which will drive the end journal to rotate. This allows the operator to perform the entry and exit and rotation operations of the end journal as needed during the installation and disassembly of the end journal, which meets the alignment adjustment of the fixing bolt holes on the aircraft.

[0031] After the end journal is installed, the installation tools need to be removed from the end journal. First, simply connect the end journal to the aircraft using bolts. The bolts do not need to be fully tightened; use the bolts to initially limit the connection between the end journal and the aircraft, preventing the end journal from rotating or shifting during disassembly. Next, the operator drives the handle 9 to rotate the disassembly handle 2 and the fixing connector 1. If the threaded connection 4 at the fixing connector 1 loosens and disengages from the end journal first, the disassembly handle 2 and the fixing connector 1 can be removed from the end journal together by turning the drive handle 9.

[0032] If the threaded connection between the threaded connector 7 and the connecting hole 6 between the disassembly handle 2 and the fixed connector 1 is released first, the disassembly handle 2 will detach from one end of the fixed connector 1 first. In order to facilitate the continued disassembly of the fixed connector 1, one end of a special wrench can be inserted into and matched with multiple grooves 11 on the outer wall of the first limiting part 5. By rotating the wrench, the fixed connector 1 can be loosened, so that the fixed connector 1 can be disassembled even if the disassembly handle 2 detaches first.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
