Definitions

  • the present invention relates to an assembly for the removable attachment of the cradle to the breech of a weapon.
  • a set is described in the preamble to claim 1.
  • a set having the characteristics of this preamble is known to the applicant.
  • the cylinder head sleeve On many weapons, disassembly of the tube barrel, and possibly its replacement, must be done from the front.
  • the cylinder head sleeve On a tank for example, before perform this disassembly, the cylinder head sleeve is connected to the turret roof by a temporary fixing adapted. The sleeve is then connected to the cradle by a flange fixed to the sleeve and the cradle by connections screw nut. This flange allows the cradle to support the weight of the sleeve effectively when this support does not is done more through the tube.
  • this type of mounting does not provide a sufficiently precise positioning of the sleeve by compared to the cradle, which often makes it tricky the installation and screwing operation of a new tube which requires that the two parts are coaxial.
  • this positioning defect leads the appearance of stresses in the brake rods and which then also contribute to support the sleeve in relation to the cradle. The degradation of these stems frequently results, which may cause degradation of the seals.
  • the invention aims to propose a set allowing the removable fixing of the cradle sleeve, ensuring axial positioning precise relative of the two parts allowing to eliminate any risk of damage to the seals.
  • the invention therefore relates to an assembly comprising a weapon fitted with a tube screwed into a breech sleeve and movable in axial translation relative to a cradle, the assembly also comprising fixing means removable from the sleeve directly to the cradle when it is in contact with it.
  • this set is characterized in that the fixing means comprise means relative coaxial centering of the cradle and the sleeve.
  • the sleeve is therefore arranged coaxially to the cradle as soon as it is in contact with it and fixed.
  • the centering means guarantee that this coaxial position will be retained for the duration fixing. No constraint appears anymore in the brake and recuperator rods, which avoids any risk of damage due to fixing imprecise.
  • the centering means also constitute means support arranged to allow the cradle to support the weight of the sleeve in the fixed position.
  • the centering means constitute also means for immobilizing the sleeve relative to the cradle in orthogonal translation at the axis of the sleeve, in the fixed position.
  • Constraints orthogonal to the axis that could undergo the sleeve and that would tend to move relative to the cradle are therefore cashed by the centering means, so that we still realize an economy of means.
  • the fixing means comprise means for immobilizing the sleeve relative to the cradle in rotation and translation relative to the axis of the sleeve.
  • the means of immobilization are distinct from means of centering.
  • the centering means are constituted by means protruding in the axial direction and recesses, respectively of the sleeve and the cradle, or of the cradle and the sleeve, the recesses being adapted to receive the protruding means.
  • the immobilization means comprise a flange having at least one protuberance, the sleeve and the cradle each having at least one conduit substantially radial, the conduits being parallel between them and arranged to receive the protuberance (s), immobilization means including means to attach the flange to the cradle and to the following sleeve the axial direction.
  • the present mode of realization of the assembly according to the invention comprises a weapon which is here a tank.
  • the barrel of the tank is provided with a tube 1 screwed into a cylinder head sleeve 2 and movable in axial translation relative to a cradle 3, according to the well-known layout.
  • Tube 1, cradle and sleeve 2 have axis 5 as their common axis when they are in this configuration.
  • the set For the dismantling of the tube 1, the set includes means for fixing the cradle 3 to the turret of the tank not shown. These means being conventional, they were not represented.
  • the set also includes removable fixing means of the sleeve 2 directly to the cradle 3 when it is in contact with it by its face 4 directed towards the sleeve.
  • the fixing means include means for relative coaxial centering of the cradle 3 and sleeve 2, that is to say allowing ensure that the sleeve and the cradle are coaxial when the sleeve 2 is fixed to the cradle 3.
  • the centering means also constitute means of support arranged to allow the cradle to support the weight of the sleeve in the fixed position, as well as means for immobilizing the sleeve 2 relative to the cradle 3 in translation orthogonal to axis 5 of sleeve, in fixed position.
  • the centering means are arranged to be in the immediate vicinity of a internal face 6, 7 of the cradle 3 and of the sleeve when the sleeve 2 is fixed to cradle 3.
  • the centering means are constituted by protruding means 9 in the axial direction and recesses 12, respectively of the sleeve and of the cradle 3, the recesses 12 being adapted to receive the protruding means 9.
  • the protruding means and the recesses could be present respectively on the cradle 3 and on the sleeve 2.
  • the means projecting are constituted by an annular edge 9 coaxial with the axis 5 of the sleeve 2 and projecting from the face 10 of the sleeve 2 which is directed towards the face 4 of the cradle 3.
  • the internal face 11 of the edge 9 is located in the extension of the internal face 7 of the sleeve 2 which is in contact with the tube 1 when the latter is installed. Edge 9 is therefore relatively close to axis 5.
  • the recesses are formed by an annular groove 12 on the face 4 of the cradle 3.
  • This groove 12 is in contact with the face internal 6 of the cradle intended to receive the tube 1 and is is also very close to axis 5.
  • the diameter and thickness of the edge 9 and the groove 12 are substantially equal, the dimensions of the edge 9 being slightly weaker than that of the throat 12 to allow the groove 12 to receive the edge 9 when the parallel faces 4 of the cradle and 10 of the sleeve 2 are in mutual contact.
  • edge 9 is sufficiently thick and the groove 12 is deep enough to allow edge 9 to support the sleeve 2 in the fixing position shown in Figure 1.
  • this thickness and this depth will be between 5 and 10 millimeters.
  • the fixing means also include means for immobilizing the sleeve 2 relative to the cradle 3 in rotation and in translation relative to axis 5 of the sleeve, the immobilization means being here distinct from the centering means.
  • the immobilization means are arranged to find in the immediate vicinity of the external faces 13 and 14 cradle and sleeve 2 when the sleeve is attached in the cradle.
  • the means immobilizer comprise a flange 15 having a first 16 and a second 17 protrusions which are respectively a tubular finger 16 and a rectangular parallelepiped 17.
  • the tubular finger is here cylindrical.
  • the sleeve 2 and the cradle 3 each have at least one substantially duct radial to axis 5.
  • the cradle has a recess tubular 18 and the cradle 3 and the sleeve 2 have first 19 and second 20 grooves respectively.
  • conduits 18, 19, 20 are parallel between them and arranged to receive the protrusions of the flange 15 when it is in the position of fixing Figures 1 and 2.
  • the tubular recess 18 can receive the tubular finger 16 and the first and second grooves 19, 20 are adapted to cooperate to receive in common the rectangular parallelepiped 17.
  • the two grooves 19, 20 constitute a housing rectangular parallelepiped adapted to receive the rectangular parallelepiped 17.
  • the grooves 19, 20 of this example pre-exist the invention and initially allow the receipt of the tube 1 stop key relative to to sleeve 2. Nevertheless, their use for welcome the rectangular parallelepiped 17 is new and is a contribution of the invention.
  • the immobilization means further include means for attaching the flange 15 to the cradle and to the sleeve 2 along the direction of axis 5, that is to say to prohibit its relative displacement following this direction.
  • These attachment means include links screw-nut, constituted by the screws 24 and the orifices threaded 25 from the front face 10 of the sleeve 2.
  • the screws 24 are arranged so that they cross two lateral notches 23 of the flange 15 and are oriented in the axial direction when the sleeve 2 is attached to cradle 3.
  • the cradle 3 is connected to the turret of the tank in a known manner.
  • the sleeve 2 is in contact with the face rear 4 of the cradle 3 because of the force generated by the recuperators, the edge 9 being in the groove 12.
  • the user removes the stop key and activates places the flange 15.
  • the conduits 18, 19 and 20 being radial to axis 5, the flange is put in place by a vertical downward movement orthogonal to axis 5.
  • the flange is shown during this movement.
  • the finger tubular 16 enters the tubular recess 18 and the rectangular parallelepiped 17 enters between the grooves 19 and 20.
  • the user fixes the flange to the face 10 of the sleeve at by means of the screws 24 passing through the notches 23 and housed in the threaded holes 25.
  • the flange 15 as that implementation is shown in Figure 2.
  • the edge 9 housed in the groove 12 ensures precise coaxial centering of the sleeve and the cradle, and prohibits any relative translation orthogonal to the axis 5.
  • the conduits 18, 19 and 20 the flange 15 is easily and precisely installed compared to cradle 3 and the sleeve.
  • the fixing of the flange by the screw 24 and engagement of finger 16 in the recess tubular 17 prohibit any relative translation of the cradle and sleeve 2 along the axis 5.
  • the grooves 19 and 20 prohibit any relative rotation of the two parts around axis 5.
  • the fixing means ensure good stress transmission between these two parts and thus protect the brake and recuperator rods.
  • the user introduces the tube in the cradle 3 and screws it into the sleeve. He removes the flange 15 and puts the key back in place stop.
