Abstract

An aircraft skin deep groove nut decomposing device belongs to the technical field of aviation decomposing devices. The aircraft skin deep groove nut decomposing device comprises a spanner, a spanner rod and a hook head. One end of the spanner rod is punched and used for penetrating through the spanner, and the spanner is in interference fit with the spanner rod; the other end of the spanner is fixed with one end of the hook head. The other end of the hook head is provided with a plum blossom opening, the hook head is perpendicular to the spanner rod, and the hook head is parallel to the spanner. Compared with the prior art, the method has the advantages that the corresponding universal wrench and standard tool are selected only manually, the method has high practicality, rapidness and accuracy, meanwhile, the disassembly efficiency of the aircraft deep groove nut can be improved, and the rejection rate of the aircraft skin deep groove nut due to disassembly can be reduced.

Description

Aircraft skin deep groove nut decomposition device

Technical Field

The utility model relates to an aircraft skin deep groove nut decomposing device, in particular to a 300 mm-thick aircraft skin deep groove nut decomposing device, and belongs to the technical field of aviation decomposing devices.

Background

The skin deep groove nut of a certain aircraft is about 300 in special depth, the more 200mm is multiplied by 200mm in limited disassembly rotation space, and due to the fact that the aircraft skin nut is rusted and difficult to disassemble, the tooth angle at the disassembly position is extremely easy to damage due to disassembly scrapping.

Compared with the prior art, the utility model has high practicability, rapidness and accuracy by only manually selecting the corresponding universal wrench and standard tool, and can improve the disassembly efficiency of the aircraft skin nut and reduce the rejection rate of the disassembled aircraft skin nut caused by disassembly.

Disclosure of Invention

The utility model provides a deep groove nut decomposing device which can accurately, quickly and effectively decompose nuts at the deep groove of an aircraft skin without damage.

The technical scheme of the utility model is as follows:

an aircraft skin deep groove nut decomposing device comprises a spanner 1, a spanner rod 2 and a hook head 3.

One end of the spanner rod 2 is punched and used for penetrating through the spanner 1, and the spanner 1 is in interference fit with the spanner rod 2;

the other end of the spanner rod 2 is fixed with one end of the hook head 3.

The other end of the hook head 3 is provided with a plum blossom opening, the hook head 3 is perpendicular to the spanner 2, and the hook head is parallel to the spanner 1;

the two end faces of the hook head 3 are parallel planes.

Further, the other end of the spanner 2 and one end of the hook head 3 are fixed in a manner of welding or integrally forming the spanner 2 and the hook head 3.

Further, the sizes of the plum blossom openings of the hook heads 3 with different types are different and are determined according to the deep groove nuts of the aircraft skin.

The utility model has the beneficial effects that: compared with the prior art, the utility model has high practicability, rapidness and accuracy by only manually selecting the corresponding universal wrench and standard tool, and can improve the disassembly efficiency of the aircraft deep groove nut and reduce the rejection rate of the aircraft skin deep groove nut due to disassembly.

Detailed Description

The utility model will now be described in detail by way of example with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides an aircraft skin deep groove nut disassembling device, which comprises a spanner 1, a spanner rod 2 and a hook head 3.

One end of the spanner rod 2 is punched and used for penetrating through the spanner 1, and the spanner 1 is in interference fit with the spanner rod 2; after the other end of the spanner rod 2 is welded and fastened with the hook head 3, the spanner rod 2 is polished smoothly.

One end of the hook head 3 is provided with a through hole, and the cylindrical end of the spanner rod 2 passes through the through hole and is welded together; the other end of the hook head 3 is provided with a plum blossom opening; the sizes of plum blossom openings of the hook heads 3 of different types are different and are determined according to the deep groove nuts of the aircraft skin.

The hook head 3 is inserted into a nut assembly part of a nut disassembly device at a deep groove of an aircraft skin, a common wrench cannot be disassembled, and the wrench 1 is rotated to drive the hook head 3 to be disassembled anticlockwise slowly in a reverse step mode.

In summary, the above embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
