Definitions

  • the invention relates to a fastening for a muzzle part on a weapon barrel according to the preamble of claim 1.
  • 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 the previous 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 unscrewing and can also be fixed in the axial direction, but the radial mobility of the muzzle part in the region of the front end of the weapon barrel can only be influenced insignificantly.
  • the body of the muzzle brake located in front of the front tube 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 such that a radial play-free connection is created between the mouth part and the weapon barrel in addition to an axial fixation and a lock against rotation and vibrations the mouth part when firing, caused by manufacturing tolerances of the fasteners, are avoided.
  • the invention advantageously provides a simple, play-free and robust type of fastening between the muzzle part and the weapon barrel by d 1 5 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 device are further advantageously kept free of external influences, so that the mouth part can be replaced at any time. Additional guides and long fastening threads can be dispensed with by 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 muzzle brake 4.1 designed as a muzzle part 4, in which an inner cone 5 is arranged in front of an internal 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 on on the external thread 3 located behind the outer cone 2, a firm, prestressed and thereby durable connection is created.
  • This connection is also radially free of play because the inner cone 5 and the outer cone 2 have a length 1 1 of greater than 1.5 d 1 self-locking at the same angle of inclination ⁇ .
  • the thread 3, 6 is designed as a fine thread for attaching and releasing the self-locking cone connection.
  • the thread 3, 6 takes over only conditional carrier function of the mouth part 4, so that its length 1 2 is smaller than the thread diameter d 2 .
  • the outer cone 2 of the weapon barrel 1 contains at least four recessed positions 8 on the circumference, segment-like, for an anti-twist device 7.
  • the anti-twist device 7 is formed by a locking pin 10 which, in securing the cone connection, extends in a bore extending transversely to the axis 9 and tangentially to the inner cone 7 11 and thus rests with its part 12 projecting into the space of the inner cone 5 against the flat bottom 13 of a grid position 8.
  • the strength and the wall thickness s of the mouth part 4 are coordinated in the length range l l in such a way with respect to the angle of inclination ⁇ and the thread pitch that when tightening by known screwing tools, not shown, known per se, an elastic expansion of the mouth part 4 in the parallel surfaces 14 of the mouth part 4 Area 11 for taking a grid position 8 of the anti-rotation device 7 is possible.
  • the width b of the bottom 13 of the grid position 8 is dimensioned such that after contacting the conical surfaces 2, 5 and the continued rotation of the mouth part 4 in the next grid position 8 of the pin 10 in the bore 11 rotated parallel to the grid position 8 to secure the Mouth part 4 can be inserted.
