Definitions

  • the subject of the present invention is a mechanism for placing ammunition in the breech chamber of a medium or large caliber weapon, comprising on the one hand a device for feeding the ammunition which is rotated by a drive device and on the other hand at least one delivery means and a means for jamming the ammunition operating successively, the delivery means and the jamming means being integral in rotation with the feed device, the latter performing during a cycle of placing the munition successively a first rotation positioning the ammunition on the one hand in the axis of the breech chamber and on the other hand the delivery means to allow it to carry out a delivery of the ammunition, and a second rotation positioning the wedging means to allow it to wedge the ammunition in the forcing cone.
  • the first and second rotations take place around two different axes, that is to say with a complex movement, hence a mechanical complexity which has as a corollary a relative mechanical fragility of the whole , not very compatible with the requirements of the new types of artillery equipment.
  • the subject of the present invention is a post-setting mechanism of the aforementioned type, but which has a mechanism which is both simpler and more robust than in the prior art.
  • the basic idea of the invention is to carry out the two rotations around a single axis so as to obtain the desired simplicity, and consequently, also to save on the time of a complete loading cycle.
  • the shift mechanism according to the invention is characterized in that it comprises a rotary part allowing the first and second rotations of the feeding device to take place around the same axis of rotation cooperating with a means of retractable stop allowing the rotation of the feed device to be stopped in a position corresponding to the end of the first rotation.
  • the retractable stop means may comprise a retracting device moving the stop means between two positions, namely a first, active position, in which the stop means is capable of causing the rotation of the device to stop. end feed first rotation, and a second position, inactive, in which the stop means is cleared and does not act on the rotation of the feed device.
  • the retractable abutment means advantageously comprises a first abutment lever sliding longitudinally relative to said rotary part, but integral in rotation with said part, the feed device comprising means for sliding the first abutment lever along said part rotatable between said first and second positions.
  • the first stop lever may in particular comprise a peripheral groove, the means for moving the first lever then comprising a fork engaging in said groove.
  • the retractable stop means comprises a second stop lever cooperating with a stop at the end of the first rotation, the first stop lever being capable of driving the second stop lever only when it is in his first position.
  • the fork can be articulated around an axis of articulation.
  • the fork may have first and second branches, each of which has a region such as a finger engaging in said groove.
  • the first branch may include, at one end, a control finger constituting said means for sliding the first stop lever.
  • the post-setting mechanism may include a rigid box supporting the drive device, the retractable stop means and said rotary part.
  • the mechanism may include means for controlling, between steps a and c , an outward movement of the delivery means so as to effect said delivery of the ammunition and for controlling, between steps c and d , an outward movement of the jamming means so as to effect said jamming of the ammunition, then a return movement of the jamming means.
  • the mechanism comprises means for controlling, during step d , a return movement of the delivery means.
  • a device for supplying ammunition 50 comprises a stretcher 1 of semi-circular shape whose concavity is directed upwards and which is provided with an anti-extraction device 4, known per se, which is intended to prevent the ejection of the shell 50 during the rotation of the stretcher 1.
  • the stretcher 1 is movable in rotation about a single axis, which is the axis of rotation of a part cylindrical 11.
  • a support comprising on the one hand a perforated plate 22 at 26 which extends radially from the cylindrical part 11 to the stretcher 1 and on the other hand two support elements lateral 24 and 25 orthogonal to the plate 22 and the ends 24 'and 25' of which enclose the stretcher 1 so as to constitute a rigid mechanical assembly.
  • the stretcher 1 is rotated by a rotary actuator 6 with a helical piston.
  • a chain repressor 2 driven by a hydraulic motor and a linear wedging cylinder 3 are mounted on the stretcher 1 and are integral with its rotation about the axis of the part 11.
  • the whole is powered by an electro-hydraulic block, itself controlled by an electric control console.
  • a lever 7 carrying a drive finger 18 is integral in rotation with the part 11, but its position along the latter is controlled by a fork 8 actuated by a stop cylinder 5.
  • This drive in rotation of the lever 7, independently of its longitudinal position along the part 11, is obtained by complementary grooves 15 of an extension 11 'of the part 11, and of the lever 7, which are shown in FIGS. 8 and 9.
  • the finger 18 of the lever 7 makes it possible to drive a second lever 9 in rotation as far as a damping stop 10. At its end 14 there is a stop finger 12.
  • the fork 8, controlled by the stop cylinder 5, makes it possible to move the lever 7 longitudinally along the axis 11 between an active position in which the pin 18 is capable of rotating the lever 9 and an inactive position in which the rotation of the lever 7 cannot have any influence on the lever 9.
  • the lever 9 is recalled by its own weight or by a spring (not shown) in a low position where it is released from the stop 10 and comes to rest in its bottom dead center on a lower edge 16 of an opening of one of the edges 34 of a support box 30 rigid U-shaped having a bottom plate 31 and a second flange 33.
  • the box 30 stiffens the assembly and carries a U-shaped plate 36, the branches 37 and 38 of which support the rotary actuator 6, the mechanism retractable stop 5, 7, 8, 9 and one end of the part 11, the other end of which is held by a wing 39 forming an extension of the bottom plate 31, which adjoins the rim 34.
  • the shift mechanism then operates according to the following cycle:
  • a shell 50 is deposited in the stretcher 1, which is in the insertion position shown in FIGS. 1 and 2. In this position, the chain repressor 2 is at rest. The linear wedging cylinder 3 is retracted rod, the stop cylinder 5 is retracted rod (see Figure 7), which corresponds to the active position of the lever 7, and the rotary cylinder 6 is at rest. The anti-extraction device 4 prevents the shell from being ejected during the first rotation movement of the stretcher 1.
  • a first angle rotation ⁇ of the stretcher 1 is carried out around the axis of the part 11 from the position shown in FIG. 1 to the position shown in FIG. 3, in which the arm 9, driven by the finger 18, is applied by its abutment finger 12 against the damping abutment 10.
  • the shell 50 has its axis aligned with that of the breech chamber 40 of the barrel and the chain repressor 2 is in a position in which it can repress the shell 50 from the stretcher 1 to the breech chamber 40.
  • This repression step is initiated by a position detector of the stretcher 1 which controls the advance of the chain repressor 2.
  • a second position detector controls the output of the rod of the stop cylinder 5, which has the effect of releasing the finger 18 from its action on the lever 9, which returns to its bottom dead center, and release the grooved lever 7 to allow it to p continue its rotation without exerting any action on the lever 9.
  • the stretcher 1 then performs a second angle rotation ⁇ , still under the action of the rotary actuator 6 left under pressure from the position shown in Figure 3 to the position shown in Figure 5.
  • the cylinder wedge 3 is brought into alignment with the cylinder head chamber 40 of the muzzle.
  • a position detector of the stretcher 1 controls the output of the rod 23 of the wedging cylinder 3 and locks in the firing position the shell 50 in the forcing cone 60 of the chamber 40.
  • An electro-hydraulic device hydraulically connected to the rod 23 of the jack 3 controls, as soon as the oil flow drops, the reentry of the rod 23.
  • a reentry detector of the rod 23 then controls the return of the stretcher 1 in starting position (FIG. 1) as well as the return of the repressor 2.
  • a last detector in the starting position controls the retraction of the stop cylinder 5, which again positions the lever 7 in the active position. The loading device is then ready for a new cycle.
  • the device which has been described above, saves time, on the one hand due to the fact that the return of the repressor 2 can be done entirely in masked time and, on the other hand that the return time of rotation of the arm is faster than in the prior art thanks to the unique movement, which contributes to reducing the time of a complete cycle and consequently improves the rate of fire of the material.
  • FIG. 7 shows the lever 7 in its active position where the pin 18 rotates the lever 9. This position corresponds to the rod 82 position retracted from the stop cylinder 5.
  • the fork 8 has the general shape of an inverted U ( see Figure 9) which has an upper central branch 84 and two lateral branches 83 and 85 which extend downwards. At its upper part 88, which surmounts the central branch 84, is disposed a hinge 89 allowing the fork 8 to be movable in rotation about a horizontal axis perpendicular to the axis of rotation of the part 11.
  • the lower part of the branch 83 has an extension 82 which ends with a finger 81 which engages in the rod 82, which makes it possible to control the movement of the fork 8.
  • the middle part of the branches 83 and 85 carries extensions 83 and 87 engaging in a groove 71 of a cylindrical part 72 extending the lever 7 along the axis of the part 11.
  • the fork 8 can thus be moved between the active position of the lever 7 (in solid lines in FIG. 10) in which the finger 18 can rotate the lever 9 and a second position making an angle with the vertical and in which, the jack 5 being in the rod 82 out position, the finger 18 is moved (to the right in FIG. 10) so as to be separated from the lever 9 (see the dotted lines in Figure 10).
  • FIG. 8 also shows the various positions of the levers 7 and 9 and more particularly the three characteristic positions of the lever 7, namely the first starting position shown in solid lines, then, after the first rotation, the first position corresponding to the setting in stop of the lever 9 (also shown in dotted lines) then finally, the rotation pushing against the clockwise direction, the third position after second rotation in which a rear extension 19 of the lever 7 abuts on a stop 13 indicating the end of the second rotation.
