Description

Hinge bracket drilling tool

Technical Field

The utility model relates to an aeronautical technology, concretely relates to connecting means of wing and flap.

Background

An airplane hinge bracket is an important mechanical device used for connecting a wing and a flap and enabling the wing and the flap to rotate relatively. The quality of the installation quality of the hinge support of the airplane directly influences the transmission effect of the guy cable on the flap, thereby generating great influence on the lift force and the resistance of the airplane. Therefore, the position accuracy of the hinge bracket mounting hole is very important, and the aerodynamic performance of the airplane is directly influenced. The diameter ratio of the hinge support mounting hole is large, and the direct drilling electric drill is easy to jump. Before drilling the mounting hole, a guide hole must be drilled first, and then the mounting hole is drilled through the guide hole, so that the electric drill is prevented from jumping and the hole accuracy is improved. The accuracy of the guide hole directly determines the accuracy of the mounting hole.

Currently, the drilling technology of the mounting hole of the hinge support of the airplane is not mature, a proper drilling tool is not designed, and the drilling is completely carried out by depending on the experience of an operator (the operator must be trained in advance). When drilling, a guide hole with the diameter of 5mm is drilled at an approximate position, so that the drill bit is prevented from jumping when drilling the mounting hole, and the error is reduced. And expanding the guide hole to 10mm to complete the drilling.

The existing drilling process has the following defects: the drilling is too dependent on the operation experience of workers, the precision of the holes is low, the lifting force and the resistance of the airplane are slightly influenced, and the appearance is influenced; the drilling operation workers must be trained firstly, so that the cost is high and the time consumption is long; the drilling time of the guide hole is as long as 5min, and the efficiency is low.

Detailed Description

As shown in fig. 2, the hinge support drilling tool is provided with a right-angle structure, a guide hole 11 is formed in a first right-angle side 10 of the right-angle structure, positioning holes are formed in a second right-angle side of the right-angle structure, the number of the positioning holes is at least two, a positioning bolt 20 is matched in any one positioning hole, and the positioning bolt can be screwed in a hinge hole 31 of a wing.

As shown in fig. 1, the wing 30 is connected to the flap 40 by a hinge 60 and a pull rod 50. Wherein the hinge is provided with a first hinge bracket connected with the wing 30 and a second hinge bracket connected with the flap. The first hinge support is L-shaped, the wing 30 comprises a wing surface 32 and a wing main body 33, a notch 34 is formed in the wing main body 33 at the right-angle edge of the wing, a right-angle edge of the L-shaped first hinge support is matched in the notch 34 and extends into the space between the wing surface 32 and the wing main body 33, and the other right-angle edge of the L-shaped first hinge support is attached to the edge side wall of the wing main body 33. Hinge hole 31 is seted up on the marginal lateral wall of wing main part 33, utilizes the mounting hole of hinge bracket drilling frock drilling from top to bottom passes wing surface 32 downwardly extending again to wing main part 33.

The guiding hole 11 with the relative position of locating hole is equivalent to the utility model discloses the relative position of the mounting hole of drilling and corresponding hinge hole also is equivalent to the relative position of the hole site on a right-angle side of first hinge bracket (this hole site can with the mounting hole is aligned) and the hole site on another right-angle side of first hinge bracket (this hole site can with the hinge hole is aligned). If hinge bracket drilling frock is placed on wing 30, and the locating hole of frock aligns with corresponding hinge hole 31, and the guiding hole 11 of frock aligns with the mounting hole. If the first hinge support is fitted to the wing 30, the hole location on one leg of the first hinge support is aligned with the mounting hole and the hole location on the other leg of the first hinge support is aligned with the respective hinge hole 31.

Because the second right-angle side 12 of hinge bracket drilling frock is laminated with the marginal lateral wall of wing main part 33, and the locating hole aligns with corresponding hinge hole, and fixes on wing 30 through positioning bolt 20, consequently, the mounting hole that obtains under the direction of the guiding hole of frock can certainly accurately align with the hole site on the right-angle side of first hinge bracket.

When the first hinge support is installed, a hole position on a right-angle side of the first hinge support is connected with the installation hole through a first bolt 61, a first bolt head sinks in the installation hole of the wing surface 32 and presses against the right-angle side of the first hinge support, and a hole position on the other right-angle side of the first hinge support is connected with the corresponding hinge hole 31 through a second bolt. Since the first bolt head is sunk at the center of the mounting hole of the wing surface 32, it is more beautiful when viewed from the wing surface.

After the positioning bolts 20 in all the positioning holes are screwed with the corresponding hinge holes 31, the height of the first right-angle edge 10 is equal to or higher than the wing surface 32. Preferably, the number of the positioning holes is two, the positioning holes are distributed on the second right-angle edge 12 up and down, and the two positioning holes are aligned with two corresponding hinge holes on the wing. After the two positioning holes are connected with the two corresponding hinge holes through the positioning bolts 20, the height of the first right-angle edge 10 is equal to that of the wing surface 32, namely, the first right-angle edge 10 is pressed against the wing surface 32.

Alternatively, the hinge bracket drilling tool 100 is L-shaped.

Hinge support drilling frock 100 is formed by the metal block cutting, and convenient for material selection, processing is convenient.

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.
