Description

Technical Field

[0001] This utility model relates to the field of aviation maintenance technology, specifically to an auxiliary tool for disassembling and assembling nuts and washers in the semi-enclosed area of ​​an aircraft. Background Technology

[0002] Some areas of an aircraft are small, with limited structural space and poor accessibility, making the installation and removal of nuts and washers in such areas extremely difficult.

[0003] A search revealed that Chinese patent CN201320509591.6 (published on January 22, 2014) discloses a tool for disassembling faulty bolts in non-open parts. The tool includes a base, a slide bar, a nut, a slide rail, a tap, a bushing, a push rod, and a handle. It can significantly improve the efficiency of disassembling faulty bolts, save a lot of manpower and rework time, and avoid a lot of rework caused by disassembling surrounding finished parts and structural parts due to the inability to disassemble faulty bolts, as well as the potential occurrence of secondary faults.

[0004] However, the above-mentioned patent has three drawbacks: First, it will damage the bolts and nuts, rendering them unusable (this tool is only suitable for disassembling faulty bolts that are no longer usable); second, this destructive disassembly method is generally inefficient, only more efficient than other destructive disassembly methods (such as drilling / milling / cutting); and third, the tool has a single function, only having the function of disassembling bolts and not having the function of installation and fastening. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes an auxiliary tool for disassembling and assembling nuts and washers in the semi-enclosed area of ​​an aircraft. This aims to solve the current problem of the inability to assemble fixed washers and nuts in the semi-enclosed area, and to simultaneously provide the functions of disassembling and installing bolts of various specifications.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] An auxiliary tool for removing and installing nuts and washers in the semi-enclosed area of ​​an aircraft, comprising:

[0008] The movable lever body is used for handheld and fixed positions;

[0009] A movable connecting rod is movably connected to one end of the movable rod body, and the movable angle is adjustable;

[0010] The nut and washer disassembly sleeve is movably connected to the other end of the movable connecting rod, and the angle of movement is adjustable. The nut and washer disassembly sleeve has a disassembly groove inside that is adapted to the nut and washer.

[0011] As a further improvement of this utility model, the disassembly and assembly auxiliary tool is made entirely of steel.

[0012] As a further improvement of this utility model, the movable rod body is generally T-shaped.

[0013] As a further improvement of this utility model, a connecting rod fixing bolt assembly is provided at the connection between the movable connecting rod and the movable rod body.

[0014] As a further improvement of this utility model, a connecting block is provided on the outer side wall of the nut and washer disassembly sleeve, and the connecting block is movably connected to the other end of the movable connecting rod.

[0015] As a further improvement of this utility model, a sleeve fixing fastener is provided at the connection between the connecting block and the other end of the movable connecting rod.

[0016] The beneficial effects of this utility model are:

[0017] This utility model provides an auxiliary tool for disassembling and assembling nuts and washers in the semi-enclosed area of ​​an aircraft. It ensures installation quality while greatly reducing secondary quality risks and shortening operation time. The disassembly function allows for convenient and quick disassembly of the nut, ensuring that the washer and nut do not fall into the semi-enclosed area and reducing the risk of the washer and nut falling into the semi-enclosed area and being unable to be removed. The tightening function ensures that the washer and nut will not fall off under force during the tightening process. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 4 As shown, an auxiliary tool for disassembling and assembling nuts and washers in a semi-enclosed area of ​​an aircraft mainly includes a movable rod body 101, a movable connecting rod 102, a nut and washer disassembly and assembly sleeve 103, a connecting rod fixing bolt assembly 104, and a sleeve fixing fastener 105. The entire disassembly and assembly auxiliary tool is made of steel.

[0026] The movable rod body 101 is used for hand-holding and fixing. The movable rod body 101 has an overall T-shaped structure to facilitate the operator's grip.

[0027] The movable connecting rod 102 is mainly used to connect the movable rod body 101 with the nut and washer disassembly sleeve 103, and provides support during tool use. Specifically, one end of the movable connecting rod 102 is movably connected to the movable rod body 101 through the connecting rod fixing bolt assembly 104, and the angle between the movable rod body 101 and the movable connecting rod 102 can be adjusted by loosening or tightening the connecting rod fixing bolt assembly 104.

[0028] The nut and washer disassembly sleeve 103 is used to fix nuts and washers that need to be disassembled or installed, and must match the dimensions of corresponding non-standard nuts and washers. Further, the nut and washer disassembly sleeve 103 has an internal disassembly and assembly groove 106 adapted to the nuts and washers; a connecting block 107 is provided on the outer side wall of the nut and washer disassembly sleeve 103, and the other end of the movable connecting rod 102 is movably connected to the connecting block 107 on the nut and washer disassembly sleeve 103 through the sleeve fixing fastener 105. The angle between the nut and washer disassembly sleeve 103 and the movable connecting rod 102 can be adjusted by loosening or tightening the sleeve fixing fastener 105.

[0029] Working principle and usage process of this utility model:

[0030] Depending on the size of the nut to be disassembled, change the specifications of the nut and washer disassembly sleeve 103. The selected nut and washer disassembly sleeve 103 is screwed and fixed to the other end of the movable connecting rod 102 by the sleeve fixing fastener 105. One end of the movable connecting rod 102 is connected to the movable rod body 101 by the connecting rod fixing bolt assembly 104. The angle between the movable connecting rod 102 and the movable rod body 101 is adjusted by loosening the connecting rod fixing bolt assembly 104. After adjustment, tighten it again to fix the state. Adjust the angle between the nut and washer disassembly sleeve 103 and the movable connecting rod 102 in the same way.

[0031] In use, the bolt is fixed and tightened on one side of the bolt head using an open-end wrench or socket wrench. Then, the operator holds the movable rod body 101 and engages the nut and washer with the disassembly and assembly slot 106 in the nut and washer disassembly and assembly sleeve 103. The nut is then disassembled by using an open-end wrench or socket wrench on the other side. The installation process is the reverse of the above disassembly process.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
