Definitions

  • the invention relates to a fastening for a muzzle part on a weapon barrel according to the preamble of claim 1.
  • two cones which can be used essentially as an anti-rotation lock, are arranged behind the screw-on thread.
  • the cone of the mouth part contains longitudinal slots, so that when screwing on, the remaining projections can spread out against the outer cone of the weapon barrel in such a way that they allow the mouth part to rotate relative to an anti-rotation lock designed as a spring tongue of at least one gap division.
  • each mouthpiece must be firmly clamped to the pipe, because if the mouthpiece is insufficiently fastened, a reduction in the accuracy of the projectiles must necessarily be expected.
  • a disadvantage of this known type of fastening is that the cone formed by the extensions forms a relatively resilient stop for the fastening thread due to the slotted design, as a result of which the mouth part can be secured against loosening and can also be fixed in the axial direction, but the radial mobility of the mouth part in the region the front end of the gun barrel can only be influenced insignificantly.
  • the body of the muzzle brake located in front of the front pipe end can swing in a vibration deflection beyond the guide play around the firmly tensioned region of the cones. Changes in the direction of the projectile and inaccuracies in the results are the result.
  • the invention has for its object to improve the attachment mentioned in the preamble of claim 1 for a muzzle part on a weapon barrel in such a way that a radial play-free connection is created between the mouth part and the weapon barrel in addition to an axial fixation and a securing against loosening and vibrations of the mouth part when firing, caused by manufacturing tolerances of the fasteners, can be avoided.
  • the invention advantageously provides a simple, play-free and robust type of fastening between the muzzle part and the weapon barrel in that in the front region of the weapon barrel the muzzle part and the weapon barrel are connected without play via relatively long conical surfaces.
  • the conical surfaces and the anti-rotation lock are further advantageously kept free from external influences, so that the mouth part can be replaced at any time. Additional guides and long fastening threads are dispensable due to the type of fastening according to the invention.
  • FIG. 1 shows a longitudinal section of the front end of a weapon barrel with a mouth part fastened thereon.
  • FIG. 1 illustrates the representation of a as Muzzle part 4 designed muzzle brake 4.1, in which an inner cone 5 is arranged in front of an inner thread 6 arranged at the rear, through which, together with an outer cone 2 located at the front end of the weapon barrel 1, when the internal thread 6 is screwed onto the external thread 3 located behind the outer cone 2 a firm, prestressed and thus durable connection is created.
  • This connection is also radially free of play, because the inner cone 5 and the outer cone 2 act on a length 1 of greater than 1.5 d 1 at the same angle of inclination a self-locking.

a) le cône extérieur (2) est placé à l'extrémité antérieure du tube (1) de l'arme devant le filetage (3) et le cône intérieur (5) à l'intérieur de la pièce de bouche (4) devant le taraudage (6);
b) les cônes (2, 5) forment, dans la zone antérieure du tube (1) de l'arme, sur une longueur 1, supérieure à 1,5 d, (d, correspond au diamètre extérieur du tube (1) de l'arme, un assemblage sans jeu radial qui ne permet pas de mouvement relatif de la pièce de bouche (4) par rapport au tube (1) de l'arme dans toute la zone de fixation, le cône intérieur (5) et le cône extérieur (2) ayant un effet autobloquant sur la longueur 1, supérieure à 1,5 d, sous le même angle d'inclinaison a;
c) dans la position de sûreté, la sûreté contre le desserrage par rotation (7) se trouve dans l'un d'au moins quatre crans (8) évidés en forme de segment à la périphérie du cône extérieur (2).
2. Fixation pour une section de bouche sur un tube d'arme selon la revendication 1, caractérisée en ce que la sûreté (7) est formée par une goupille de sûreté (10) placée dans un alésage (11) s'étendant transversalement à l'axe (9) et tangentiellement au cône intérieur (5), qui est, en position de sûreté, par sa partie (12) pénétrant à l'intérieur du cône, en contact avec le fond plat (13) d'un cran (8).
3. Fixation pour une section de bouche sur un tube d'arme selon l'une des revendications 1 et 2, caractérisée en ce que pour la fixation et le desserrage, le filetage et le taraudage (3, 6) sont réalisés sous la forme de filets à pas fins, et présentent une longueur 12 relativement courte, inférieure au diamètre nominal d2.
