Definitions

  • the invention relates to a barrel weapon according to the preamble of claim 1.
  • the means for fixing the weapon barrel in the loading position contain a lever U which can be manually flipped, and by means of which it operates axially. Slidable coupling disengages a leveling gear, so that a pivoting of the weapon barrel from the firing position into the loading position without leveling gear is made possible by a further lever X. Characterized in that the gun barrel is disengaged when pivoting into the loading position relative to the leveling gear, pivoting into the loading position can only be achieved with a tail-heavy weapon barrel, the gun barrel resting only on the lever X in the loading position. A bracket that could prevent the weapon barrel from escaping upwards is not provided.
  • the weapon barrel can only be held securely in the firing position by the leveling mechanism, so that a secure holding function in the loading position, for example, cannot be achieved with a weapon side directional part that is constantly changing relative to a horizontal position, as a result of which a short-time supply of the cartridges from a fully automatic loading device is not possible is.
  • Another device for decoupling a leveling machine from a weapon barrel to ensure a manual pivoting movement of the weapon barrel into the loading position is known from DE-C-308557.
  • the weapon barrel In the loading position, the weapon barrel must be held by a friction clutch arranged on the weapon height-adjusting part due to the disengaged height-leveling machine. Due to the manual operation to carry out the swiveling movement, a short-term adjustment due to the friction clutch and a precise adjustment of the weapon barrel in an index position necessary for the loading process cannot be achieved, especially since the horizontal position (loading position) of the weapon barrel can only be seen by a Lybelle, for example. Necessary corrections of the friction clutch and a cumbersome check by the Lybelle disadvantageously cause a further loss of time, so that such locking of the gun barrel is also unsuitable for a fully automatic loading device operating at high cadence.
  • locking teeth engage in a dental arch.
  • the ratchet teeth are, however, freely movable in one direction of movement of the weapon barrel, so that a locking position of the weapon barrel secured in the loading position upwards and downwards against vibrations cannot be achieved.
  • the locking mechanism of the teeth is connected to the closure in such a way that it can only perform its movements as a function of the closure movements. Therefore, this locking device also does not allow a short-term, safe and precise locking of the weapon barrel in the index position to ensure an automatic loading process.
  • GB-A-296716 shows a control device which can be actuated by a hand lever and with which different weapon functions are carried out in a controlled manner depending on the respective position of a shaft which can be rotated by the hand lever.
  • the control device a way is for example shown to control the movements of the arms h ö- henrichtmaschines through hydraulic valves, and to actuate for a stop of the elevating part in the loading position, a mechanical linkage. Means that hold the weapon height adjustment part securely and precisely in the loading position are not disclosed, however.
  • the invention has for its object to provide an automatically drivable locking device for a tube weapon of the type mentioned, through which the weapon height adjustment part of the tube weapon compared to a fully automatic loading device during a short loading time in a constantly constant index position is adjusted safely and precisely.
  • a safe and precise adjustment of the weapon height adjustment part in an index position is achieved independently of time-consuming loading position corrections by an automatically driven locking device arranged on the weapon side adjustment part and on the weapon height adjustment part.
  • the locking device enables the required power for the rotation of a claw driven and braked by a drive and brake unit to be provided by a motor in a very short time via a gear mechanism which is matched in terms of the rotational speed and the torque, and that the braking process has sufficient power Security for locking the bolt is guaranteed.
  • this locking device is advantageous in the case of a fully automatic loading device arranged separately from the weapon height adjustment part in that a constant index position for the loading process is always achieved even under weapon-independent interference, especially if disruptive influences constantly impair the loading position, for example in the case of continuously changing positions the weapon side and weapon height standard.
  • the design of the claw is particularly advantageous in that even before half the maximum locking rotation of the claw has been reached, the bolt attached to the weapon height adjustment part is held in a position in which only a minimal movement stroke of the height adjustment part is permitted and therefore, when this stop position is reached, the load-bearing organs of the height-adjusting part can be switched off via a limit switch device, but can already take over the carrying function of the height-adjusting part again in the holding position after the loading process and the claw has been turned back.
  • the diametrical arrangement of identical jaws on the claw allows, in the unlocked position of the claw, a swiveling up and down of the oval bolt attached to the weapon height adjustment part around the shield pin axis, while by a certain rotational movement of the claw, firstly due to the ovality of the bolt and secondly the shape of the exchangeable wear plates that are resistant to abrasion means that the space between the pin and the wear plates is rapidly reduced, with the diametrically arranged surfaces of the wear plates locking the pin in coordinated steps.
  • the shaping and material coordination of wear plates and bolts represent a further advantage because the locking function is guaranteed even in the event of short-term high shock loads.
  • the locking device by attaching the locking device in the area between the shield pin axis and the lock, preferably in the vicinity of the lock, by locking in the index position, an exact loading position is always achieved, with a correction of the adjustment of the bolt relative to the claw in the direction of the tube core axis being possible and manufacturing tolerances in the axial direction of the bolt can be compensated for by the locking device.
  • a height adjustment part 1 which can be pivoted about the axis 28, with a weapon barrel 4, which is displaceable in a barrel weapon storage 6 in the direction of the barrel core axis 31, is held in an index position 5 of the pivoting range necessary for the loading process.
  • This index position is achieved by a bolt 7 fastened to the barrel weapon storage and a claw 9 rotatable about the bolt 7, which is driven and braked by a drive and brake unit 8 fastened to the weapon side direction part 2 so that it can be rotated back and forth.
  • the bolt 7, which can be swiveled up and down by the index position 5, can be adjusted by fastening means 30, for example screws, on a holder 43 cast, welded or screwed onto the barrel weapon storage, with an exact position of the bolt in the direction of the barrel core axis 31 relative to the claw axis by shifting the guide means 32 is possible, for example by means of a groove and an attachment.
  • FIG. 2 shows the index position 5 of the pivotable about the axis 28 within the angle of rotation ⁇ Pipe core axis 31 of the gun barrel.
  • This constantly recurring and precisely maintained index position required for the loading process is achieved by a specific shape 22 of the jaws 12, by means of which the metal body 34 of the bolt 7 (FIG. 1), which is oval in cross section, can be locked.
  • FIG. 3 illustrates the fastening of the holder 43 to the barrel weapon bearing 6 in the vicinity of the breech 33 in the region between the breech 33 and the cradle body 29 which can be rotated about the shield pin axis 28.
  • the bolt 7 connected to the holder is located within the jaws formed by the claw 9 12 in the unlocked position, so that due to the free spaces 11 between the outside of the pin 7 and the inside 14 of the jaws 12 of the pin 7 with connected weapon height adjustment part, the weapon height adjustment movement can be carried out in the pivoting range of the angle of rotation ⁇ (FIG. 2).
  • the claw 9 can be driven about the axis 41 via a gear 38 which is matched by the motor 37 with regard to torque and rotational speed and via a powerful brake 39 can be braked with sufficient safety in the locking position of the bolt 7 (FIG. 1).
  • This process is therefore quick, accurate and continuously repeatable because a limit switch device 40, which monitors the rotary movement of the claw 9, is arranged on the gear 38, which is connected to the weapon side directional part, by means of the electrical control signals to the motor 37 and to the brake 39 and to the load-bearing organs of the weapon height adjustment part are forwarded during locking and unlocking.
  • FIG. 4a illustrates the design of the jaws 12 in detail.
  • Both jaws 12 have bevels 15 in the insertion area towards the outer jacket 19, to which each jaw 12 is connected by a U-shaped recess 16 opening to the axis 41, in which a wear plate 20, which is provided with a shape 22 consisting of surfaces 23, 24, 25, 26, 27, is interchangeably arranged via fastening means 21.
  • the wear plates 20 are fixed diametrically by the side surfaces 17 and the base surfaces 18 of the U-shaped recess 16, the base surface 18 being arranged asymmetrically with respect to the center line 42.
  • the metal body 34 has an oval cross-sectional area similar to an ellipse with a broad axis 36 standing perpendicular to the longitudinal axis 35.
  • the jaws 12 of the claw 9 are in the unlocked waiting position in relation to the metal body 34, in which the wear plates 20 are arranged on both sides to the left and right of the metal body 34 in such a way that, despite a stabilization system, specific vibration causes a contact between the metal body 34 and the surfaces 23 to 27 the wear plates 20 cannot take place.
  • FIG. 4b illustrates the holding position of the metal body 34 by the surfaces 26 of the wear plates 20 within the driven claw 9. In this position, the oscillating movement is reduced to the minimal play between the surfaces 26 and the metal body 34.
  • the surface 26 has already reached this holding position during the locking before the center line 42, which is still horizontal in FIG. 4a, with the wide axis 36 has formed half the angle of rotation of the maximum possible rotational movement for the locking.
  • FIG. 4c shows the locking position of the metal body 34 through the diametrically lying surfaces 24 of the locking plates 20 after the claw 9 has been rotated further into the end position.
  • the metal body 34 shown as a bolt 7 (FIG. 1) with an oval cross section, is turned to the center line 42 after the further rotation of the center line 42, which is still horizontal in FIG. 4a, with respect to the wide axis 36, which can be between 90 ° and 130 ° Ends of the longitudinal axis 35 are held firmly by the sides 24 by positive locking.
  • an electromechanically operated locking device ensures that the indexing of the weapon height leveling part, which is necessary for the loading process compared to a separate loading device, is achieved securely, quickly and precisely by positive locking, the locking device being characterized by high wear resistance and easy interchangeability of the wearing parts and by precise Adjustment possibility distinguished.
  • the locking device has an elec instead of the electro-mechanical drive equip tro-hydraulic control.
