Abstract

The invention discloses a barrel assembly of a barrel-rotating weapon, which comprises a barrel, a cover plate, a joint sleeve, a bearing ring, a positioning hoop, a positioning screw sleeve, a barrel hoop part, a barrel hoop fixing pin, and a muzzle device; the barrel and The joint sleeve is connected by thread; the outer circle of the body tube is provided with an anti-rotation plane, the cover plate is provided with a through hole, and the inner circular surface of the through hole is provided with one or several anti-rotation planes fitted with the anti-rotation plane on the body tube. Rotation plane; the cover plate and the barrel are fitted through the anti-rotation plane; each barrel is equipped with a positioning screw sleeve, a positioning hoop and a muzzle device, and the positioning screw sleeve ensures that the axis position is consistent, the bearing ring is installed around the front, and the positioning hoop is clamped Tighten the bearing ring and the positioning screw sleeve; the body pipe hoop part is connected and fixed with the bearing ring through the body pipe hoop fixing pin. The invention simplifies the assembly process, and improves the precision of the barrel itself without damaging the base body of the barrel. The barrel assembly of a rotating barrel weapon of the present invention is reliable in fixing, simple in structure, and good in assembly process.

Description

technical field [0001] The invention relates to the technical field of conventional revolving weapons, in particular to the barrel assembly structure of revolving weapons. Background technique [0002] The barrel assembly of conventional rotary weapons generally consists of 3 barrels (or more), a section sleeve and a barrel hoop. The barrel is fixed on the section sleeve, and the barrel hoop provides radial positioning for the barrel and improves the barrel. Axial stiffness to ensure shooting accuracy. In the process of shooting, after the bullet is fired, several hundred megabytes of chamber pressure are generated in the barrel of the barrel, and the rotation of the projectile in the barrel produces a certain force on the barrel. The reliability of the light weapon can only be guaranteed by ensuring that the barrel is fixed reliably. and precision performance. [0003] Common ways of fixing the barrel, the sleeve and the barrel of the transfer weapon include bolt fixing, ...
