Description

Technical Field

[0001] This invention relates to the field of aircraft equipment, specifically to an auxiliary device for disassembling an aircraft generator. Background Technology

[0002] When an aircraft generator malfunctions, it needs to be promptly removed from the aircraft and transported to the appropriate repair shop for disassembly and repair. In some cases, the removed hex bolts are unusable after disassembly, requiring the use of new ones. Under efficient repair conditions, the new hex bolts must be moved one by one to the repair loading point before being tightened and installed, making the entire operation relatively cumbersome. Summary of the Invention

[0003] To assist in the manual loading of new external hexagonal bolts to the maintenance point, this invention proposes an auxiliary device for disassembling aircraft generators.

[0004] The technical problem to be solved by this invention is achieved by the following technical solution:

[0005] An auxiliary device for disassembling an aircraft generator includes a working frame. A release control component and an external hexagonal nut unloading and sorting component are mounted on the right side of the working frame; a transport component is mounted on the left side of the working frame; and a main extraction component is connected to the transport component. The external hexagonal nut unloading and sorting component is used for storing and unloading external hexagonal bolts. The release control component is used to move the unloaded external hexagonal bolts to a loading point for easy extraction. The main extraction component is used to extract the external hexagonal bolts, and after extraction, the external hexagonal nuts are transported by the transport component.

[0006] The transport assembly includes a chain mounted on a work support frame and a U-shaped frame mounted on the chain. The U-shaped frame is driven by the chain for transport.

[0007] The main retrieval assembly includes an I-type motor, a vertical guide rod, and a lead screw connected to the I-type motor, all mounted on a U-shaped frame. A pickup seat, which slides along the vertical guide rod, is threaded onto the lead screw. The lead screw is mounted on the U-shaped frame via bearings. Thus, the pickup seat can move up and down via the lead screw and nut transmission.

[0008] The pickup base has a regular hexagonal groove at its bottom; the main extraction assembly also includes hydraulic cylinders and double guide rods, both mounted on the pickup base; the hydraulic cylinders are connected to an extension plate that slides with the double guide rods; the extension plate is equipped with a clamping assembly. The regular hexagonal groove can mate with the head of an external hexagonal bolt. The clamping assembly can easily clamp the head of the external hexagonal bolt. The extension plate can be controlled to rise and fall.

[0009] The clamping assembly includes a Type II motor mounted on the pickup base, a spur gear connected to the Type II motor, and two lateral racks meshing with the spur gear; each lateral rack is connected to an L-shaped clamping rod. Through the gear and rack mechanism, the two L-shaped clamping rods can slide towards or away from each other along with the corresponding two lateral racks, thereby clamping or releasing the external hexagonal bolts.

[0010] Preferably, both sides of the pickup base are welded with horizontal shafts that slide in cooperation with the L-shaped clamping rod.

[0011] The beneficial effects of this invention are:

[0012] This invention is easy to operate, and can stably discharge the stored hexagonal bolts one by one to the indicated position. It can also stably clamp and extract the discharged hexagonal bolts, and transport the extracted hexagonal bolts to a specific maintenance point for release and loading, thereby facilitating disassembly and repair work.

[0019] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below with reference to the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present invention and not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0020] like Figure 1 As shown, an auxiliary device for disassembling an aircraft generator includes a working frame 1. A release control component and an external hexagonal nut unloading and sorting component are mounted on the right side of the working frame 1; a transport component is mounted on the left side of the working frame 1; and the transport component is connected to a main extraction component. The external hexagonal nut unloading and sorting component is used for storing and unloading external hexagonal bolts. The release control component is used to move the unloaded external hexagonal bolts to the loading point for easy extraction. The main extraction component is used to extract the external hexagonal bolts, and after extraction, the external hexagonal nuts are transported by the transport component.

[0021] like Figure 1 As shown, the transport assembly includes a chain 2 mounted on the working support frame 1 and a U-shaped frame 3 mounted on the chain 2. That is, the U-shaped frame 3 is driven by the chain 2 for transport.

[0022] like Figure 1 As shown, the main extraction assembly includes an I-type motor 4, a vertical guide rod 5, and a lead screw 6 connected to the I-type motor 4, all mounted on a U-shaped frame 3. A pickup seat 7, which slides on the vertical guide rod 5, is threaded onto the lead screw 6. The lead screw 6 is mounted on the U-shaped frame 3 via bearings. Thus, the pickup seat 7 can move up and down via the lead screw and nut transmission.

[0023] like Figure 2 As shown, the pickup base 7 has a regular hexagonal groove 7a at its bottom end; the main extraction assembly also includes a hydraulic cylinder 8 and a double guide rod 9, both mounted on the pickup base 7; the hydraulic cylinder 8 is connected to an extension plate 10 that slides with the double guide rod 9; the extension plate 10 is equipped with a clamping assembly. The regular hexagonal groove 7a can mate with the head of an external hexagonal bolt. The clamping assembly can easily clamp the head of the external hexagonal bolt. The extension plate 10 can be controlled to rise and fall.

[0024] like Figure 2 As shown, the clamping assembly includes a Type II motor 11 mounted on the pickup base 7, a spur gear 12 connected to the Type II motor 11, and two lateral racks 13 meshing with the spur gear 12; each lateral rack 13 is connected to an L-shaped clamping rod 14. That is, through the gear and rack engagement, the two L-shaped clamping rods 14 can slide towards each other or away from each other along with the corresponding two lateral racks 13, thereby clamping or releasing the external hexagonal bolts.

[0025] like Figure 2As shown, both the left and right sides of the pickup seat 7 are welded with horizontal shafts 15 that slide in conjunction with the L-shaped clamping rod 14. The above is a conventional design for a sliding structure.

[0026] like Figure 2 As shown, the external hexagonal nut unloading and sorting assembly includes a side extension seat 16 mounted on the right side of the working auxiliary frame 1, a main material bin 17 mounted on the side extension seat 16, and a transport frame 18 located below the main material bin 17; the transport frame 18 is provided with a transport groove 18a and a side groove 18b respectively. The main material bin 17 is provided with a vertically penetrating hexagonal groove, the cross-sectional shape of which corresponds to the head shape of the external hexagonal nut.

[0027] like Figure 1 , Figure 3 as well as Figure 4 As shown, the delivery control assembly includes a carrier plate 19 abutting against the lower end of the main material hopper 17, and the carrier plate 19 slidingly engaging with the side groove 18b; the carrier plate 19 has a pushing surface 19a; the working auxiliary frame 1 has a protrusion 1a; a spring 20 connected to the protrusion 1a and the carrier plate 19 is provided between the two. That is, the carrier plate 19 is slidable and subjected to the elastic force of the spring. The lower end of the carrier plate 19 abuts against the transport frame 18, and the height of the carrier plate 19 corresponds to the height of the bolt head of a single external hexagonal bolt.

[0028] like Figure 4 As shown, the carrier plate 19 is connected to a translation rack 21, which meshes with an arc rack 22. The arc rack 22 is connected to a type III motor 23. That is, through the cooperation of the arc rack 22 and the translation rack 21, and under the action of spring force, it can move back and forth left and right, thereby stably driving the external hexagonal bolt to the loading point.

[0029] like Figure 4 As shown, the Type III motor 23 is fixedly mounted on the working bracket 1. The above is a conventional design for the fixed structure.

[0030] Before use, simply stack the external hexagonal bolts in the hexagonal groove inside the main material bucket 17 with the bolt heads facing upwards, so that the bolt part of the bottom external hexagonal bolt is inserted into the transport groove 18a, and the bolt head of the bottom external hexagonal bolt abuts against the pushing surface 19a.

[0031] In use, the arc rack 22 is driven to rotate counterclockwise by the type III motor 23, so that the carrier plate 19 pushes the external hexagonal bolt to the left. After the arc rack 22 engages and disengages from the translation rack 21, the external hexagonal bolt is discharged.

[0032] Furthermore, the chain 2 transports the pickup seat 7 to directly above the hexagonal bolt after it is discharged. Then, the type I motor 4 drives the lead screw 6 to rotate, causing the pickup seat 7 to move down and allowing the head of the hexagonal bolt to be inserted into the regular hexagonal slot 7a.

[0033] Furthermore, the hydraulic cylinder 8 pushes the extension plate 10 upward, causing the lower parts of the two L-shaped clamping rods 14 to support the bolt head of the external hexagonal bolt. Then, the type II motor 11 drives the spur gear 12 to rotate clockwise, allowing the two lateral racks 13 to slide towards each other, thereby clamping the external hexagonal bolt. At this point, the extraction work is completed.

[0034] Finally, the extracted hexagonal bolts are carried upwards away from the transport trough 18a and, under the action of chain 2, are continued to be transported to the maintenance point for release, thus completing the loading work.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely prisms of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
