Description

Technical Field

[0001] This utility model belongs to the field of wing maintenance and relates to an auxiliary tool for disassembling and assembling bolts on wing panels. Background Technology

[0002] When maintaining the wings and internal equipment, it is necessary to open the removable wing panel assemblies. Because the wings are exposed to a complex environment, the bolts connecting them exhibit varying degrees of corrosion, which can lead to stripping when disassembling them with ordinary tools. Currently, operators use electric drills or pneumatic tools with hammering functions to disassemble stripped bolts, which can damage the support nuts on the panel and even damage the panel structure. This method is unsuitable for routine field maintenance of aircraft and carries certain risks. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an auxiliary tool for disassembling and assembling wing panel bolts, which is suitable for the on-site construction environment and meets the needs of disassembling panels when maintaining wings both on and off the field.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An auxiliary tool for disassembling and assembling wing panel bolts includes a torque rod, a fulcrum lifting component, and a bolt disassembly connector;

[0006] The front end of the torque rod is rotatably connected to the fulcrum lifting component, and the bottom of the fulcrum lifting component is provided with a connection through hole; the top of the bolt removal joint is slidably connected to the torque rod, the bottom of the bolt removal joint is rotatably connected to its top, and the bottom of the bolt removal joint is provided with an internal hexagon.

[0007] Preferably, the fulcrum lifting component includes a bracket, a connector, and a lifting component. The top of the bracket is rotatably connected to the front end of the torque rod. The two ends of the connector are respectively connected to the bottom of the bracket and the top of the lifting component. The bottom of the lifting component is provided with a connection through hole.

The torque rod is rotatably connected to the top of the bracket by bolts and nuts, and the torque rod is located between the two arms of the bracket.

[0009] Furthermore, the bolts are fitted with arc-shaped washers located on the inner sides of the two support arms of the bracket, in contact with the outer wall of the torque rod.

[0010] Furthermore, a through hole is provided at the center of the bottom of the bracket, and a support nut is installed above the through hole. The support nut is connected to the bracket by rivets. One end of the connector is provided with an external thread that matches the support nut on the bracket and is connected to the bracket.

[0011] Furthermore, the outer diameter of the bottom end of the connector is smaller than the inner diameter of the lifting member, and both the bottom end of the connector and the top end of the lifting member are provided with radial center through holes, through which pins are used.

[0012] Furthermore, a chain is installed on the pin, and the chain is connected to a link. The link is located above the lifting member on the connector, and a nut is installed below the link on the connector.

[0026] like Figure 1 As shown, the auxiliary tool for disassembling and assembling wing panel bolts according to this utility model consists of three parts: a torque rod 1, a fulcrum lifting component 3, and a bolt disassembly joint 2.

[0027] like Figure 2 As shown, the fulcrum lifting component 3 consists of four parts: a bracket 5, a connector 6, a lifting component 7, and a pin 11. The bracket 5 has a U-shaped structure. Both arms of the bracket 5 have through holes at their tops, and the bottom center of the bracket 5 also has a through hole. A support nut 8 is installed above the through holes and connected to the bracket 5 by rivets. One end of the connector 6 is configured with an external thread matching the support nut 8 on the bracket and connects to the bracket 5. The outer diameter of the other end of the connector 6 is smaller than the inner diameter of the lifting component 7, and it has a central through hole at its bottom that matches the lifting component 7. The lifting component 7 is a cylindrical cavity with a pin 11 at its bottom. A circular connecting hole is provided to match the screws on the wing panel. This circular connecting hole allows the fulcrum lifting member 3 to rotate freely and adjust its direction. A center connecting hole matching the connecting member 6 is provided on the side. A pin 11 is passed through the center connecting holes on the connecting member 6 and the lifting member 7 to connect the connecting member 6 and the lifting member 7 radially. A chain 10 is provided on the pin 11. The chain 10 is connected to the chain link 9. A nut is used to fix the chain link 9 to the part of the connecting member 6 above the lifting member 7 through the thread of the connecting member 6. The nut is located below the chain link 9 to prevent it from being lost during use.

[0028] like Figure 3As shown, the bolt removal connector 2 consists of three parts: a T-shaped sleeve 12, a bearing 13, and a rotating threaded sleeve 14. The inner diameter of the T-shaped sleeve 12 matches the outer diameter of the torque rod 1. The T-shaped sleeve 12 is fitted over the torque rod 1 and is slidably connected to it. The T-shaped sleeve 12 can slide freely on the torque rod 1. A pin fixing hole matching the torque rod 1 is provided on the T-shaped sleeve 12. The bearing 13 is connected to the T-shaped sleeve 12 via a snap ring. The top of the rotating threaded sleeve 14 and the bottom of the T-shaped sleeve 12 are respectively connected to the inner and outer rings of the bearing 13. The bearing 13 and the rotating threaded sleeve 14 are welded together. When the rotating threaded sleeve 14 is rotated with an open-end wrench, the bearing 13 can protect and support it. The rotating threaded sleeve 14 consists of two external hexagonal threaded sleeves. The diameter of the lower external hexagonal sleeve is smaller than that of the upper external hexagonal sleeve, and the lower external hexagonal sleeve has an internal hexagonal thread for installing and removing nut bits.

[0029] like Figure 1 As shown, the torque rod 1 is a rigid structural component of the circular tube type. Multiple fixing pin holes matching the bolt disassembly joint 2 are provided on its circumferential surface. These fixing pin holes are arranged axially at intervals to adjust the axial position of the bolt disassembly joint 2 on the torque rod 1. The bolt disassembly joint 2 is fixed to the torque rod 1 by fixing pins 4. The front end of the torque rod 1 has a radial through hole matching the fulcrum lifting member 3 for the bolt to pass through. The torque rod 1 and the top of the bracket 5 of the fulcrum lifting member 3 are rotatably connected by bolts, arc-shaped washers, and nuts. The torque rod 1 is located between the two arms of the bracket 5. The arc-shaped washer is placed on the bolt and is located on the inner side of the two arms of the bracket 5, contacting the outer wall of the torque rod 1.

[0030] During implementation, remove the pin 11 from the fulcrum lifting member 1 to separate the connecting member 6 from the lifting member 7. Align a hole on the wing panel and use screws to connect the lifting member 7 to the wing panel. Install the bit corresponding to the bolt to be disassembled on the bolt disassembly joint 2. Reinstall the pin 11 on the fulcrum lifting member 3 to assemble the connecting member 6 and the lifting member 7. Align the bit with the bolt to be disassembled by sliding the bolt disassembly joint 2 on the torque rod 1. Fix it with the fixing pin 4 through the corresponding hole at the upper end of the torque rod 1 and the bolt disassembly joint 2. Press down on the end of the torque rod to fix the relative position of the bit and the bolt to be disassembled. Use an open-end wrench to rotate the rotating sleeve 14. Rotating the sleeve 14 will cause the bolt to rotate, and the bolt can be removed. After the bolt is removed, remove the bit and the lifting member 7, thus completing the disassembly of the wing panel bolt.
