Definitions

  • the present invention relates to a percussion device for an automatic tube weapon of the type with internal energy source (for example of the gas borrowing type) or with external energy source.
  • the object of the present invention is to propose a percussion device overcoming the drawbacks of the devices according to the state of technique.
  • the invention consists in securing the striker to the operating part during the locking phase, then to the movable head during the start phase of the blow.
  • the device offers a very high level of security because the percussion is controlled, that is to say carried out at a very precise instant determined during the design of the mechanism.
  • Another advantage is due to the fact that the impact energy is very high since the complete inertia of the moving parts of the weapon participates in the percussion, the striker being linked to the operating part.
  • the percussion device according to the invention is completely passive when the bolt is in the rear position because there is no stored energy. This is not always the case for known devices using springs, which can be detrimental for safety in the event that the spring retaining stop would break.
  • the percussion device for an automatic weapon with a tube comprises: a maneuvering part moving alternately and parallel to the axis of the tube, a movable head intended to come to bear on the tube, carried by the maneuvering part and sliding relative to the latter following a first so-called locking stroke ensuring the attachment of the movable head to the tube and at the end of which the percussion takes place, then a second so-called damping stroke, and a striker sliding in the movable head.
  • FIG. 1 represents a percussion device comprising an operating part 1 constituted by a tubular part of axis X X ′ coinciding with the barrel of the weapon surmounting a prismatic part on which are fixed four guide rollers 2 bearing on a beam not shown secured to the frame and the tube tear.
  • This operating part comprises a bore 3 of axis YY 'perpendicular to the axis XX' in which is housed an axis 4 carrying a roller 5 and a shoe 6 circulating along a groove of a rotary drum not shown, thus ensuring the reciprocating movement of the mobile assembly to allow the introduction of the ammunition into the barrel of the weapon.
  • the axis 4 is extended by a cylindrical part 4a passing through the tubular part of the operating part 1.
  • the movable head 7 is constituted by a tubular part 7a sliding in the tubular part of the operating part and by a cylinder head 7b coming to take support on the barrel of the weapon (not shown) to close the propulsion chamber when the ammunition is inserted.
  • This movable head further comprises two diametrically opposite ramps 8A and SB which the cylindrical part 4A of the axis 4 crosses.
  • This ramp consists of a helical part A - B (see FIG. 2) and a rectilinear part B - C.
  • the helical part AB is used to ensure the locking of the movable head on the barrel of the weapon.
  • the maneuvering piece advances towards the barrel of the weapon, the movable head abuts on the latter, then the axis 4 following the ramp AB rotates the head which locks at the level of the rear surface 9 of the teeth 10 on a shape complementary to the barrel of the weapon.
  • the rectilinear part BC of the ramp is a damping stroke used, in this particular example, in the event of a long fire, that is to say a delay in the initiation of the propellant charge or no start of the blow.
  • the rotary drum providing alternative guidance for the mobile assembly 7 is driven by an external energy motor of the electric motor type.
  • This device includes means sensitive to the information "start of the shot” constituted by sensors determining the longitudinal position of the weapon relative to the cradle on which it is arranged.
  • the locking means are constituted by latches 11 (shown diagrammatically in FIG. 3) coming to bear at the rear of the operating part 1.
  • this type of percussion device can be used by a conventional weapon with an internal energy source, the stroke AB serving to ensure the locking of the movable head on the barrel of the weapon and the stroke BC being used to cushion the end of travel of the mobile assembly.
  • the device according to the invention further comprises a striker 12, sliding along a bore 13 produced in the movable head 7, in which a counter striker 14 can be moved linked to the operating part 1 by the axis 4.
  • the striker and the counter-striker are held by a pin 15, the ends of which are connected to the striker and sliding in an oblong groove 16 made in the counter-striker 14.
  • the connecting device (FIG. 4) of the movable head t with the percuteuz R and of the striker with the counter-striker 14 comprises two crutches 17 articulated on the striker along axes 18 orthogonal to the axis XX *.
  • the crutches have a first cylindrical surface 19 capable of sliding inside the surface 13 of the movable head when the said crutches are in the retracted position, and a second surface 20 that can slide on the lateral surface 21 of the counter-striker when the crutches link the striker to the moving part.
  • a flat 22 is formed at the end of the crutches so as to secure the striker-movable head block, by bearing on the surface 23 of a notch 24 produced on the movable head.
  • a second flat 25 cooperates with a shoulder 26 of the counter-striker 14 to ensure the connection between striker and striker. It should be noted that all the surfaces 22, 23, 25 and 26 are inclined relative to the axis XX 'so as to facilitate the movement of the crutches.
  • the crutches 17 tilt so as to secure the striker 12 to the movable head while the striker is detached from the counter-striker (see FIG. 3), the movable head continues its relative movement (stroke BC) relative to the operating part 1
