Definitions

  • the invention relates to a device for temperature control of detonators on large-caliber projectiles, the detonator being arranged coaxially at the top of the projectile and having a part that is fixed relative to the projectile and an adjusting part that can be rotated about the projectile axis, and both parts in their lateral surface, each with one in a projectile axis Containing plane lying locking groove are provided with the features from the preamble of claim 1.
  • double detonators which, in addition to the impact, also cause the projectile to ignite after an adjustable period of time, independently of the impact.
  • the detonators arranged at the top of the projectile generally have a part that is fixed with respect to the projectile and one around them Projectile axis rotatable adjusting part, on which the tempering, that is, the setting of the ignition timing, was previously carried out by hand. It has been found that the existing manual adjustment tools sometimes did not allow satisfactory operation, especially when the adjustment had to be made within the confined space of a main battle tank or a howitzer. The reasons for this are the ergonomic conditions in the storey magazine room.
  • a device with the features from the preamble of claim 1 is described in CH-A-0 069 792.
  • GB-A-0 555 249 a device for tempering detonators, which is designed as a simple hand-held device, with two coaxially arranged and mutually rotatable ring-shaped components, which are placed on the projectile tip so that the outer, on its top, a scale-bearing component is opposite the fixed part of the igniter, while the inner component, which can be rotated by handling, is opposite the adjusting part.
  • the necessary adjustment angle is set by hand and can be read on the scale.
  • Ch-A-0 080 982 which is placed on the top of the projectile and operated by hand and has two mutually rotatable coaxial rings, one of which is provided with a scale ring for reading the adjustment angle.
  • the invention has for its object to change a device for temperature control of detonators on large-caliber projectiles with the features from the preamble of claim 1 so that a safe and accurate automatic adjustment of the detonator is possible even in tight conditions.
  • the angle between the displaceable first locking pin and the fixed second locking pin is changed by rotating the second adjusting ring with respect to the first adjusting ring and set so that the angular distance between the two locking pins corresponds exactly to the angle of rotation by which the adjusting part the detonator is to be turned towards the fixed part for temperature control.
  • the device is placed on the projectile in such a way that the fixedly arranged second locking pin engages in the locking groove of the rotatable adjusting part of the detonator after a corresponding rotary movement.
  • the two adjusting rings are rotated together by a motor until the displaceable first locking bolt, which runs along the outer jacket of the fixed part of the igniter, engages in the locking groove of the fixed part.
  • the adjustment part has then been rotated exactly by the set angle and the existing torque limitation prevents further rotation of the adjusting rings.
  • the detonator is temp.
  • the device according to the invention allows all detonators which are to be set to the same point in time to be automatically temperature-controlled.
  • the presetting of the angle between the two locking bolts is facilitated in that a scale ring, visible from the outside, with a corresponding angle scale is firmly inserted in the first adjusting ring and a viewing window provided with a line mark is arranged on the second adjusting ring, so that when the two adjusting rings are rotated against each other the adjustment angle can be read exactly.
  • the scale ring can be designed to be exchangeable so that different scales can be used for different types of detonators.
  • the device for tempering detonators shown in FIGS. 1 to 3 has an essentially ring-shaped housing 1 with a handle 2 fastened to the housing in the radial direction pointing outward.
  • the first adjusting ring 3 is rotatably mounted in the housing 1 via a pivot bearing 3.3 and is held by a holding ring 3.1 which is inserted into the housing from below in FIG. 2 and is firmly connected to the adjusting ring 3.
  • the bearing play is adjusted by inserting shims 3.2.
  • a second adjusting ring 4 is inserted therein, which can be rotated relative to the first adjusting ring 3 and can be fixed in any angular position by an eccentric clamp 5 relative to the first adjusting ring 3.
  • the eccentric clamp 5 is actuated via a wing screw 5.1, which is connected to an eccentric 5.2, which can rest against a clamping piece 5.3 in a rubber ring, which is arranged on an inner surface of the first adjusting ring 3.
  • the upper side of the device in FIG. 2 is referred to as the “upper side” and the lower side in FIG. 2 as the “lower side”.
  • the device can of course be used in any position in the room. In general, it is placed on the projectile tip in the position shown in FIG. 2 when the projectiles are upright, as is indicated by dashed lines in FIG. 2.
  • the inner contour of the two collars 3 and 4 is adapted to the outer contour of the detonator arranged at the top of the projectile.
  • the second adjusting ring 4 is inserted into the first adjusting ring 3 in such a way that two ring-shaped partial areas of the two adjusting rings are accessible from above at the top of the device, namely an annular partial area of the second adjusting ring 4 on the inside and an annular partial area of the first adjusting ring 3 on the outside
  • This outer section of the first adjusting ring 3 is designed as a separate scale ring 6, which is exchangeable and is connected in a rotationally fixed manner to the first adjusting ring 3 via a pin connection 6.1 and is held by means of a retaining ring 1.1 connected to the housing.
  • this scale ring 6 carries a scale calibrated in the usual way, which is matched to the types of detonators used and is designed as a time scale.
  • a reading window 7 is used which is fixedly connected to the second adjusting ring 4 and in the opening of which a prismatic plate 7.1, which is provided with a knitting mark 7.2 and is made of transparent material, is arranged.
  • an illumination lamp 8 is used, the electrical connections of which are electrically connected via sliding contacts 8.1 to a first pair of slip rings 8.2, which is arranged in a surface section of the first adjusting ring 3, which lies opposite the underside of the second adjusting ring 4.
  • This first slip ring pair 8.2 is connected via lines, not shown, to a second pair of slip rings on the outer surface of the first adjusting ring 3, which, as can be seen in FIG. 3, via sliding contacts 8.4 and not shown, through the housing 1 via a switch 16 and the handle 2 guided lines is connected to a connector 15 on the handle 2.
  • first locking pin 9 Arranged in the first adjusting ring 3 on the inside in a radial direction against the force of a compression spring 9.1 is first locking pin 9, which projects into the interior of the first adjusting ring 3 in the relaxed position of the compression spring 9.1 and can be displaced outward as far as possible against the force of the compression spring 9.1 is that it no longer protrudes into the interior of the first adjusting ring 3.
  • a second locking pin 10 projecting into the interior of the second adjusting ring is likewise fixedly arranged on the inside of the second adjusting ring 4.
  • the two locking bolts are located one above the other and, depending on the angular position between the first adjusting ring 3 and the second adjusting ring 4, are offset from one another by a predetermined angle.
  • Fig. 1 the relative position of the locking bolts 9 and 10 is indicated.
  • the locking pin 10 is not shown in FIG. 2, but folded into the plane of line III-III in Fig. 1, so that it appears in Fig. 3.
  • the first adjusting ring 3 is connected via a toothed ring 3.4 arranged on its outer circumferential surface to a torque limitation generally designated by reference numeral 11, the ten ring 3.4 of the first adjusting ring 3 engaging in the toothing 11.11 of the driven part 11.1 of the torque limitation 11.
  • the output part 11.1 of the torque limiter 11 is connected to the drive part 11.2 via balls 11.12 which are arranged in bores of this part and are under the force of springs 11.13.
  • the detachable connection between the output part 11.1 and the drive part 11.2 is provided in that the balls engage under the pressure of the springs 11.13 in recesses 11.21 on the drive part 11.2 and disengage from these recesses when a maximum permissible torque is exceeded and thus the connection between the drive part 11.2 and the output part 11.1 to solve.
  • the maximum permissible torque is set via an adjusting part 11.14, which serves as a counter-bearing for the springs 11.13 and can be brought into different positions by means of an adjusting screw 11.15, in which it can be fixed by a locking screw 11.16.
  • Output part 11.1 and drive part 11.2 are mounted in the housing via bearings 11.17 or 11.22 and 11.23.
  • the drive part 11.2 is connected to the drive motor 14 via an angular drive 12 and a reduction gear 13.
  • the reduction gear 13 and the drive motor 14 are arranged within the handle 2 and the electrical supply lines for the drive motor 14, not shown, coming from the plug connection 15 are also guided via the switch 16, which is designed as a multi-function switch, for example a push-button on-off switch is.
  • the scale ring 6 necessary for the type of detonator to be set is inserted into the first adjusting ring 3 and positioned in its position by means of the pin connection 6.1.
  • the device with the connector 15 is connected, for example, to the electrical power supply of a combat vehicle via a connecting cable.
  • the eccentric clamp 5 is first released and the second adjusting ring 4 is rotated relative to the first adjusting ring 3 until the mark 7.2 of the reading window 7 is above the desired time mark on the scale ring 6. Then the second adjusting ring 4 is fixed relative to the first adjusting ring 3 by locking the eccentric clamp 5. If necessary, this process can be carried out with the scale illumination switched on, which is done by actuating switch 16 (on-off function).
  • the prism plate 7.2 of the reading window transmits the illuminating energy of the lamp 8 to the scale ring 6.
  • the two locking bolts 9 and 10 are automatically brought into a predetermined angular distance from one another.
  • the torque limitation 11 is set by means of the adjusting screw 11.15 to a predetermined maximum torque, which can be, for example, between 10 Nm and 15 Nm. The position is secured by the locking screw 11.16.
  • any number of detonators can now be set.
  • the device is placed in the horizontal position shown in FIG. 2 on the vertical floor from above.
  • the drive starts and the drive motor 14 transmits the rotational energy to the first adjusting ring 3 via the reduction gear 13, the angular drive 12 and the torque limiter 11.
  • This rotates together with the second adjusting ring 4 until the fixed locking pin 10 engages in the locking groove on the rotatable upper part of the igniter. So that the upper part of the igniter is positively connected to the rotating first collar 3.
  • the device slides a little deeper, so that the inner contours of the second and first adjusting ring bear against the outer contour of the detonator, and the resilient locking pin 9, which is opposite the fixed part of the detonator, is pressed outwards by the detonator jacket.
  • the reaction torque minus the frictional torque of the first adjusting ring 3 must be picked up by the operator on the handle 2 by the drive.
  • the tempering process is now complete and the device is removed from the igniter and the next igniter can be tempered.
