Description

Technical Field

[0001] The utility model relates to the technical field of disassembly and assembly of aircraft brake discs, and more specifically, to a disassembly and assembly tool for aircraft main wheel hub brake disc bolts. Background Art

[0002] During the disassembly and installation process of the aircraft brake disc, the fixing bolts on the aircraft brake disc need to be disassembled and assembled. Since the aircraft brake disc is relatively low in height and the working space is narrow, the bolt position is relatively hidden and the force required for disassembly and assembly is relatively large. The existing disassembly and assembly mostly lengthens the wrench length to reduce the force required for disassembly and assembly, and another person is required to support the wrench to prevent the wrench from falling off the bolt. This disassembly and assembly method has low stability and convenience. Therefore, in view of this problem, how to design a disassembly and assembly tool for the aircraft main wheel hub brake disc bolts has become a problem that we currently need to solve. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a disassembly and assembly tool for the main wheel hub brake disc bolts of an aircraft, by providing a fastening plate, by sleeve-fitting the sleeve onto the bolt, and by rotating the handle to rotate the shaft rod, so that the lifting block is raised, prompting the transmission part to flip, and the bolt is clamped by multiple fastening plates to prevent the sleeve from falling off, thereby improving the convenience of disassembly and assembly to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a disassembly and assembly tool for aircraft main wheel hub brake disc bolts, comprising a main body, a connecting piece is provided at the bottom of the main body, a sleeve is fixedly installed at the bottom of the connecting piece, a transmission piece is rotatably connected inside the connecting piece, the transmission piece is slidably connected inside the sleeve, a fastening plate is fixedly installed at the bottom end of the transmission piece, the number of the fastening plates is set to be multiple, and the multiple fastening plates are evenly distributed in a circular array about the vertical center line of the sleeve, a lifting block is slidably connected inside the connecting piece, a roller is rotatably connected to one side of the lifting block, the roller and the transmission piece are arranged in a close fit, a transmission rack is fixedly installed on the top of the lifting block, and a shaft is rotatably connected inside the main body.

[0011] Technical effects and advantages of the utility model:

When the aircraft main wheel hub brake disc bolt is disassembled and assembled, the sleeve is sleeved on the bolt, and the shaft is rotated by turning the handle, so that the lifting block is raised, prompting the transmission member to flip, and the bolt is clamped by multiple fastening plates to prevent the sleeve from falling off, thereby improving the stability and convenience of the bolt disassembly and assembly, and can effectively improve the efficiency of the brake disc bolt disassembly and assembly;

[0013] 2. The utility model provides a ratchet and a braking pawl. When the shaft rod rotates, the ratchet is driven to rotate at the same time.

DETAILED DESCRIPTION

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

[0020] Refer to the instruction manual Figure 1-4 ,like Figure 1 As shown, a disassembly and assembly tool for the main hub brake disc bolt of an aircraft according to an embodiment of the utility model comprises a main body 1, a connecting member 2 is provided at the bottom of the main body 1, and a sleeve 3 is fixedly installed at the bottom of the connecting member 2. Figure 2 As shown, the connecting member 2 is internally rotatably connected to a transmission member 4, and the transmission member 4 is slidably connected to the inside of the sleeve 3. A fastening plate 5 is fixedly installed on the bottom end of the transmission member 4. The number of fastening plates 5 is set to multiple, and the multiple fastening plates 5 are evenly distributed in a circular array about the vertical center line of the sleeve 3. The connecting member 2 is internally slidably connected to a lifting block 6, and a roller 7 is rotatably connected to one side of the lifting block 6. The roller 7 and the transmission member 4 are arranged in a close fit. A transmission rack 8 is fixedly installed on the top of the lifting block 6. The main body 1 is internally rotatably connected to a shaft rod 9, and a transmission gear 19 is fixedly installed on the outer side of the shaft rod 9. The transmission gear 19 is arranged in a meshing state with the transmission rack 8.

[0021] It should be noted that, when the aircraft main wheel hub brake disc bolts are disassembled and assembled, the sleeve 3 is sleeved on the bolt, and the shaft 9 is rotated by turning the handle 12, thereby driving the transmission gear 19 to rotate and meshing with the transmission rack 8, thereby driving the lifting block 6 to rise. When the lifting block 6 rises, the roller 7 limits the transmission member 4 to flip the transmission member 4, and at the same time the roller 7 rotates to reduce the friction with the transmission member 4. As the roller 7 gradually rises, the transmission member 4 drives the fastening plate 5 to flip, so that multiple fastening plates 5 clamp and fix the bolts, avoiding the sleeve 3 from falling off during disassembly and assembly, and by sleeve-lengthening the handle on the outer side of the second grip 13, the required force can be reduced, thereby improving the stability and convenience of the bolt disassembly and assembly, and effectively improving the efficiency of the brake disc bolt disassembly and assembly.

[0022] Further, such as Figure 1 As shown, a first handle 10 is fixedly mounted on one end of the main body 1, a shaft 9 is rotatably connected to the inside of the first handle 10, a ratchet 11 is fixedly mounted on the outside of the shaft 9, a rotating handle 12 is fixedly mounted on one end of the shaft 9, and a second handle 13 is fixedly mounted on the inside of the rotating handle 12, as shown in FIG. Figure 3 As shown, a support shaft 14 is fixedly installed inside the first handle 10, and a brake pawl 15 is rotatably connected to the outer side of the support shaft 14. A fixed connecting plate 16 is fixedly installed on the top of the brake pawl 15. A spring 17 is provided on one side of the fixed connecting plate 16. The spring 17 is fixedly installed on the outer side of the first handle 10, and a shift plate 18 is fixedly installed on one end of the fixed connecting plate 16.

[0023] It should be noted that, when the shaft 9 rotates, the ratchet 11 will be driven to rotate at the same time. Under the tensile action of the spring 17, the braking pawl 15 will engage and limit the ratchet 11 to prevent the ratchet 11 from reversing. Therefore, when the fastening plate 5 clamps the bolt, the ratchet 11 is fixed by the braking pawl 15, thereby preventing the lifting block 6 from descending. By pulling the paddle 18, the fixed connecting plate 16 drives the braking pawl 15 to flip, so that the braking pawl 15 is separated from the ratchet 11, thereby stopping the limitation of the ratchet 11 and allowing the fastening plate 5 to be reset, thereby achieving the locking effect of the shaft 9 and improving the stability of the bolt when fixed.
