Definitions

  • the invention relates to a wedge lock for a weapon with one versus one Pipe cradle retractable weapon barrel and a bottom piece in which a cross to the barrel core axis Slidably arranged locking wedge that can be actuated by an opening shaft is provided.
  • the invention has for its object to provide a simply constructed wedge lock, with which an automatic opening of the breech with a high shot sequence is possible is without the need for an additional external drive.
  • the invention is essentially based on the idea, similar to weapons with a bottom lock a cam track on a cradle-fixed guide device for guidance to provide a bolt-shaped driver, but not the driver directly causes a lifting and lowering of the locking wedge, but a rotation of the opening shaft causes which in turn on the locking wedge, e.g. via a gear or Lever gear, acts.
  • the guide device has a guide of the driver when returning the gun barrel one compared to the highest Point of the cam track on the lower straight guideway, which is in the entry area the ascending curve path merges with at least the one at the inlet area subsequent area of the rising cam track of the guide device as Switch is designed for the returning cone-shaped driver.
  • the cam track consists of at least two adjoining sections
  • Such a guide device has the advantages, among other things, that when returning only the first section of the gun barrel is rotated by the peg-shaped driver whose mass is small, so that for a quick firing sequence to values> 15 m / s can be accelerated.
  • section-like structure of the cam track ensures that at wear of the cam track, which preferably consists of a hardened material not the entire management device needs to be replaced, but only that Part that was particularly stressed.
  • cam track has an approximately sinusoidal shape Has history. This will ensure a smooth and jolt-free sliding movement of the pin-shaped Carrier ensured during the opening stroke.
  • the peg-shaped driver is supported not only on the curved track, but also by one above the curved track Arranged fixed curve guided so that the driver along an ascending groove-shaped recess is guided.
  • the upper curve prevents that at high Forward speeds of the gun barrel (e.g. 2.5 m / s) the breech does not is thrown outwards.
  • the length of the first section of the curved track is at least 60% of the length of the entire cam track.
  • a base plate is provided, to which the second part bearing the second section of the cam track is fixed and the the second section of the cam track bearing second part is pivotally attached.
  • Fig. 1, 1 is a weapon with a barrel that can be retracted relative to a pipe cradle 2 3 designated.
  • the weapon barrel 3 is connected at the rear to a base piece 4, which receives a cross wedge 5.
  • the cross wedge lock 5 comprises a slidably arranged transverse to the tube core axis 6 Locking wedge 7 and an opening shaft 8 shown in broken lines, which with opening levers 9 is connected, which engage the locking wedge 7 on opposite sides.
  • the opening shaft 8 on its right facing the pipe cradle 2 Side connected to a control lever 10 to which a peg-shaped driver 11 is attached is. This driver 11 engages in a guide device attached to the cradle 2 12 a.
  • the guide device 12 comprises a pipe cradle 2 e.g. screwed and off Cast iron existing base plate 13 (Fig.3) on which to guide the driver 11 when Advance of the gun barrel 3 one from an inlet area 14 to a highest Point 26 rising cam track 15 (Fig.2) is arranged, which is approximately sinusoidal Owns rise.
  • a pipe cradle 2 e.g. screwed and off Cast iron existing base plate 13 (Fig.3) on which to guide the driver 11 when Advance of the gun barrel 3 one from an inlet area 14 to a highest Point 26 rising cam track 15 (Fig.2) is arranged, which is approximately sinusoidal Owns rise.
  • An upper side wall 16 is provided at a predetermined distance from the cam track 15, which has the same course as the cam track 15, so that the driver 11 is guided in a groove-shaped recess 17.
  • the cam track 15 is composed of two adjoining sections 18, 19, wherein the first section 18 of the curved path 15 by a first, directly on part 20 of the guide device 12 adjoining the inlet area 14.
  • This first part 20 is also made of cast iron (e.g. 14NiCr18 steel investment casting) and is about an axis provided perpendicular to the longitudinal axis of the peg-shaped driver 11 22 is pivotally arranged on the base plate 13 of the guide device 12 and is in its rest position shown in Figure 2 held by a plunger 23 (Fig.3).
  • This pestle 23 is acted upon by a spring 24 which is supported on the base plate 13.
  • the second section 19 of the cam track 15 is fixed to the base plate by a second one 13 connected and also made of cast iron part 25 is formed.
  • the guide device 12 for guiding the driver 11 has Return of the barrel 3 relative to the highest point 26 of the curved path 15 lower straight guideway 27, which in the inlet area 14 of the cam track 15 passes.
  • the shot causes the projectile a recoil, the weapon barrel 3 together with the bottom piece 4 to the rear moves (indicated by the arrow 100 in FIG. 1).
  • the cone-shaped glides Driver 11 on the guide track 27 also to the rear and pivots with it First section 18 of the cam track 15 provided first part 20 of the weapon barrel 3 laterally in a corresponding recess of the cradle 2, so that the driver 11 largely reaches the inlet area 14 of the cam track 15 unhindered.
  • the cone-shaped passes Driver 11 the rising cam track 15 (Fig.2) and causes the pivoting of the control lever 10 and the rotation of the opening shaft 8 a pivoting of Opener lever 9 (Fig. 4 dashed line) and thus an opening of the locking wedge 7th (Fig. 5 dashed representation).
  • the new floor is attached by means of a loading machine (not shown) and the introduction of a new propellant.
  • a release lever By means of a release lever (not shown) the wedge 7 is closed, the peg-shaped driver 11 the steeply sloping transition region 28 between the curved path 15 and the guideway 27 follows, so that the weapon barrel 3 is closed by the downward falling wedge 7 becomes. Then the next shot can be triggered.
