Technical Field

The invention belongs to the field of mechanical equipment, and particularly relates to a hinge structure of a transverse folding wing of a projectile body.

Background

The folding wing is one of missile wings, is connected with a missile body through a folding mechanism, and can be folded in the missile body or on the surface of the missile body before the missile is launched. The folding wing is also widely applied to aircraft carriers, thereby increasing the number of the aircraft carriers and improving the battle effectiveness. The root and the outer wing of the transverse folding wing of the projectile body need to be connected through a hinge device so that the wing can be folded and extended freely. However, the existing horizontal folding wing hinge of the projectile body is designed to be simpler than the traditional hinge structure, is only a common hinge structure, has poor limiting effect on the wing root and the outer wing, is easy to loose after being used for too long time, and causes the wing root and the outer wing to be incapable of aligning with the locking device, thereby affecting the normal work of the folding wing.

Disclosure of Invention

In view of this, the invention provides a hinge structure of a horizontal folding wing of a projectile body, which has a good limiting effect on a wing root and an outer wing, is not easy to loosen, ensures that the wing root and the outer wing are accurately aligned with a locking device, and prolongs the service life of the folding wing.

The technical scheme for realizing the invention is as follows:

a hinge structure of a transverse folding wing of a projectile body comprises a first rotating plate, a second rotating plate, a circular track rod, a first limiting plate and a second limiting plate;

the first rotating plate is fixedly connected to the wing root, the second rotating plate is fixedly connected to the outer wing, arc-shaped mounting holes are formed in corresponding positions of the first rotating plate, the second rotating plate, the wing root and the outer wing, and the circular track rod sequentially penetrates through the wing root, the first rotating plate, the second rotating plate and the outer wing; the first limiting plate and the second limiting plate are arranged between the first rotating plate and the second rotating plate, and the included angle between the first limiting plate and the second limiting plate is determined according to the limit positions of the wing root and the outer wing and is welded on the circular track rod.

Further, the first rotating plate, the second rotating plate, the wing root, the outer wing and the circular track rod are in transition fit.

Furthermore, the first rotating plate, the second rotating plate, the circular track rod, the first limiting plate and the second limiting plate are made of stainless steel.

Further, the first rotating plate is fixedly connected with the wing root through screws.

Further, the second rotating plate is fixedly connected with the outer wing through screws.

Has the advantages that:

in the scheme of the invention, when the wing root and the outer wing rotate relatively, the wing root and the outer wing rotate along the orbital ring, the whole process has good stability and is not easy to loosen. When the rotating plate is attached to the limiting plate, the wing root and the outer wing are prevented from rotating again. The hinge structure of the transverse folding wing of the missile body has good limiting effect on the wing root and the outer wing, is not easy to loosen, ensures the accurate alignment of the wing root and the outer wing with the locking device, and prolongs the service life of the folding wing.

Detailed Description

The invention is described in detail below by way of example with reference to the accompanying drawings.

With reference to fig. 1, 2 and 3, the hinge structure of the transverse folding wing of the projectile body of the invention comprises a first rotating plate and a second rotating plate 4 which are respectively attached and fixedly connected to the bottoms of the wing root 1 and the outer wing 2, wherein the first rotating plate and the second rotating plate 4 are respectively fixedly connected with the wing root 1 and the outer wing 2 through screws, arc-shaped mounting holes 7 are respectively formed in corresponding positions of the first rotating plate, the second rotating plate 4, the wing root 1 and the outer wing 2, circular rod-shaped track rods 3 penetrate through the mounting holes 7 of the first rotating plate, the second rotating plate 4, the wing root 1 and the outer wing 2, and two flat limiting plates, namely a first limiting plate and a second limiting plate 5, are arranged on the track rods 3.

First commentaries on classics board, second commentaries on classics board 4 are made by the stainless steel, and are sturdy and durable, and corrosion resisting property is good, and first commentaries on classics board, second commentaries on classics board 4 all open have with 6 complex screw holes of screw. Circular track pole 3, first limiting plate and second limiting plate 5 are made by the stainless steel, and are sturdy and durable, and corrosion resistance is good, and circular track pole 3 all passes through welded connection with first limiting plate, second limiting plate 5. The screws 6 are all made of stainless steel, and the screws 6 are all national standard parts, so that the replaceability is strong, and the manufacturing cost is low. The mounting holes 7 of the first rotating plate, the second rotating plate 4, the wing root 1 and the outer wing 2 are in transition fit with the circular track rod 3.

When the transverse folding wing hinge structure of the projectile body is installed, the first rotating plate and the second rotating plate 4 can be fixedly connected with the wing root 1 and the outer wing 2 respectively through the screws 6, then the circular track rod 3 sequentially penetrates through the installation holes 7 of the wing root 1, the first rotating plate, the second rotating plate 4 and the outer wing 2, and then the first limiting plate and the second limiting plate 5 are fixedly connected with the circular track rod 3 in a set angle (determined according to the limit positions of the wing root 1 and the outer wing 2). When the wing root 1 and the outer wing 2 receive the action of external force, the wing root 1 and the outer wing 2 rotate along the circular track rod 3, the stability of the whole process is good, and the hinge structure is not easy to loosen. When the first rotating plate is attached to the first limiting plate, the second rotating plate 4 is attached to the second limiting plate 5, and then the wing root 1 and the outer wing 2 are prevented from rotating again. The hinge structure of the transverse folding wing of the missile body has good limiting effect on the wing root 1 and the outer wing 2, is not easy to loosen, ensures that the wing root 1 and the outer wing 2 are accurately aligned with the locking device, and prolongs the service life of the folding wing.

In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
