Description

Drilling tool for wing aviation wire harness guide pipe

Technical Field

The utility model relates to an aviation technology, concretely relates to drilling equipment of wing.

Background

With the rapid development of economy in China, the domestic market of the general-purpose aircraft is gradually opened, and the number of the general-purpose aircraft and the operation market are rapidly increased. The market demand of the current general-purpose aircraft is still limited, and the automatic drilling technology of the general-purpose aircraft does not have scale effect and only can be mainly used for drilling by hand. Therefore, how to design a more efficient drilling tool becomes a main difficulty in aircraft assembly.

A wing avionics harness guide tube (hereinafter referred to as a wing guide tube 41) is an important component for fixing and guiding a navigation circuit tube 42, and holes need to be drilled in a wing before the wing guide tube 41 is installed as shown in fig. 1. The existing drilling process is to clamp the wing guide pipe inside the wing, use the wing guide pipe as a tool, and drill holes along the hole 43 of the wing guide pipe from the inside of the wing by using an electric drill. Drilling from the inside of the wing, the position of an electric drill is difficult to place, a drill bit is easy to jump, the drilling efficiency is low, the average drilling time is 30 minutes, the hole precision is low, and the rejection rate of the hole reaches 10%.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: holes are drilled from the inner part of the wing, the position of an electric drill is difficult to place, and the drilling efficiency is low; the electric drill is easy to jump and the precision of the hole is low.

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a wing aviation wire harness guiding tube drilling frock, includes frock body and a plurality of spacing part, and the frock body profile modeling is in the wing root, and first drilling guide structure sets up in spacing part, and this spacing part is located the outside of wing, and a plurality of spacing parts can make frock body and wing root coincidence with wing root structure cooperation.

The tool body is coincided with the root of the wing, the first drilling guide structure is aligned with the drilling position of the wing, the drill bit extends into the first drilling guide structure, and a hole position for installing the wing guide pipe is drilled on the wing.

Because the tool body is coincided with the wing root due to the matching of the plurality of limiting parts and the wing root structure, the matching of the drilling tool and the wing is stable, the electric drill is not easy to jump, and the precision of the hole is high.

The limiting part provided with the first drilling guide structure is positioned outside the wing, so that the electric drill is easy to place in position, and the drilling efficiency is high.

The invention will be further explained with reference to the drawings:

FIG. 1 is a partial schematic view of a wing guide tube 41 installed at the root 40 of a wing;

fig. 2 is a schematic view of a local structure of the drilling tool of the present invention engaged with the root portion 40 of the wing.

The symbols in the drawings illustrate that:

10. a tool body; 11. a second drill guide structure;

20. a stopper portion;

30. a first drill guide structure;

40. a wing root; 41. a wing guide tube; 42. aerial electric line pipe; 43. holes of the wing guide tubes; 44. the wing root fore rib.

Detailed Description

With reference to fig. 1 and 2, a drilling tool for a wing aviation wire harness guide tube comprises a tool body 10 and a plurality of limiting parts 20, wherein the tool body is profiled at the root of a wing, a first drilling guide structure 30 is arranged on the limiting parts, the limiting parts are located outside the wing, and the limiting parts can be matched with the structure of the root of the wing to enable the tool body to coincide with the root of the wing 40.

The wing root 40 includes a wing root end surface that engages the fuselage, and a wing root sidewall. According to the prior art, when a mounting hole for mounting the wing guide pipe 41 is processed, an operator clamps the wing guide pipe inside the wing, the wing guide pipe is used as a tool, and a hole is drilled on the side wall of the root part of the wing from the inside of the wing along the hole 43 of the wing guide pipe by an electric drill. According to the utility model discloses a design, a plurality of spacing parts 20 and wing root structure cooperation and make frock body 10 and wing root terminal surface coincidence, the first drilling guide structure 30 that sets up on spacing part aligns with the wing drilling position promptly. Then, the operator can drill a hole for installing the wing guide tube 41 on the side wall at the root of the wing by extending the drill bit into the first drilling guide structure outside the wing.

Wherein, the quantity of spacing part 20 is two at least, moreover, has two spacing parts and the cooperation of the lateral wall of wing root 40 at least, because: two groups of hole sites for installing the wing guide tubes 41 are provided, and two groups of first drilling guide structures 30 for drilling the two groups of hole sites are respectively arranged on the two limiting parts. Among the plurality of stopper portions, there may be a single stopper portion or a plurality of stopper portions that only serve a stopper function, in addition to the two stopper portions provided with the first drill guide structure 30.

The structure of the wing root cooperating with the plurality of retainers 20 may be a structure on the end face of the wing root, or a structure on the side wall or sidewalls of the wing root.

Alternatively, the plurality of limiting portions 20 can be matched with the outer side wall of the wing root 40 to enable the tool body 10 to coincide with the wing root. Namely, the plurality of limiting parts are in an outer surrounding potential to the wing root. Thus, an operator can conveniently enable the tool body 10 to coincide with the end face of the wing root.

Alternatively, the tool body 10 and the limiting portion 20 are cut from a laminated plate and then bonded by an adhesive. The manufacturing method is simple, the materials are easy to obtain, and the cost is low.

The wing root 40 is provided with a wing root front rib 44 which is positioned in the wing root and is close to the end surface of the wing root. The tool body 10 is provided with a second drilling guide structure 11, and under the condition that the tool body is superposed with the end face of the wing root, the drill bit extends into the second drilling guide structure 11, so that a wing root front rib hole can be drilled on the wing root front rib 44 and used for connecting a fuselage. Therefore, drilling frock, not only can make things convenient for the high-efficient installation hole site of getting wing guiding tube 41 of boring, can also bore under the condition of location once and get wing root front rib hole, improve the efficiency of wing root drilling.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
