Abstract

A device for adjusting a fuse in the tip of a large-caliber projectile without actually touching it. The device is provided with a programming station that has an annular or cylindrical programming coil mounted on it coaxially with the longitudinal axis of the resting projectile and communicating with electric controls. The tip of the projectile extends into the coil at least while the fuse is being adjusted. The programming coil slides back and forth axially paralleling the resting projectile relative to the programming station. A Y shaped grip that secures the projectile is positioned facing the side of the coil toward the projectile. The grip is shaped to accommodate the tip of the projectile. The grip moves along with and axially parallels the coil. The tip of the projectile fixes the projectile grip when it is accommodated therein. The coil can be moved out of a disengaged position relative to the projectile grip and into a fuse-measuring position wherein the distance between the projectile grip and the coil is established by stops.

Description

Die Erfindung betrifft eine Vorrichtung zur berührungslosen Zündereinstellung für großkalibrige Geschosse mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1. Eine derartige Vorrichtung ist aus der US 4 686 885 bekannt.The invention relates to a device for contactless Detonator setting for large caliber projectiles with the features from the preamble of the claim 1. Such a device is known from US 4,686,885.

Bei Panzerhaubitzen, wie sie beispielsweise in EP 0 331 980 B1 und DE 36 42 920 C2 beschrieben sind und bei denen die Geschosse mittels einer Geschoßzuführungsvorrichtung automatisch von einem Geschoßmagazin in den Bereich hinter das Waffenende befördert werden, ist es notwendig, an einer vorgegebenen Stelle dieses Geschoßzuführungsweges vor dem Ansetzen den Zünder automatisch einzustellen. Dies erfolgt in bekannter Weise mittels einer an eine elektrische Steuereinrichtung angeschlossenen Programmierspule. Das Geschoß muß so geführt werden, daß die Geschoßspitze zur Zündereinstellung in den Innenraum der Programmierspule hineinragt. Hierzu werden die Geschosse im allemeinen in eine Klappschale eingelegt, an deren Ende die Programmierstation angeordnet ist. Bei bekannten Vorrichtungen hat sich nun herausgestellt, daß es einerseits bei der aufeinanderfolgenden Zündereinstellung von Geschossen mit unterschiedlicher Länge nicht einfach ist sicherzustellen, daß die Geschoßspitze wirklich an der richtigen Stelle innerhalb der Programmierspule liegt und andererseits kam es beim Einfahren der Geschosse in die Programmierspule mit einer bestimmten Geschwindigkeit und deren Abbremsung in der Programmierspule zu Beschädigungen empfindlicher Zünder.For self-propelled howitzers, such as in EP 0 331 980 B1 and DE 36 42 920 C2 are described and in which the projectiles by means of a projectile feeding device automatically from a storey magazine transported to the area behind the weapon end be, it is necessary to follow a given Place this projectile feed path before attaching automatically adjust the detonator. This is done in known manner by means of an electrical Control device connected programming coil. The projectile must be guided so that the top of the projectile for ignition adjustment in the interior of the Programming coil protrudes. For this, the floors generally put in a folding tray, at the end of which the programming station is arranged. In known devices it has now been found that on the one hand it is in the successive Ignition setting of projectiles with different Length is not easy to ensure that the top of the bullet really in the right place lies within the programming coil and on the other hand it came when the projectiles were inserted into the programming coil at a certain speed and braking them in the programming coil leads to damage sensitive detonator.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur berührungslosen Zündereinstellung für großkalibrige Geschosse mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1 so auszubilden, daß insbesondere bei einer Haubitze mit automatischem Geschloßfluß unterschiedlich lange Geschosse mit programmierbaren Zündern berührungslos eingestellt werden können, indem ein immer gleicher Abstand des Zünders von der Programmierspule unabhängig von der Geschoßlänge sichergestellt ist und Beschädigungen des Zünders beim Einfahren in die Programmierspule ausgeschlossen werden.The invention has for its object a device for contactless ignition adjustment for large caliber bullets with the characteristics from the The preamble of claim 1 should be designed so that especially for a howitzer with automatic lock flow storeys of different lengths with programmable ones Igniters can be adjusted without contact can by keeping the detonator always the same distance from the programming coil regardless of the floor length is ensured and damage to the Igniter ignored when entering the programming coil become.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.This object is achieved with the invention the features from the characterizing part of the claim 1. Advantageous further developments of the invention are described in the dependent claims.

Der Grundgedanke der Erfindung besteht darin, nicht das Geschoß in die Programmierspule hineinzubewegen, sondern das Geschoß an seiner Spitze mit einer Geschoßhaltegabel festzuhalten und dann die Programmierspule in axialer Richtung zu verschieben, bis diese in einer Meßstellung einen durch Anschläge vorgegebenen Abstand vom Zünder hat, so daß die Zündereinstellung vollständig berührungslos erfolgen kann.The basic idea of the invention is not to move the bullet into the programming coil, but the bullet at its tip with a bullet holding fork and then hold the programming coil to move in the axial direction until this one in a measuring position predetermined by stops Distance from the detonator so that the detonator setting can be done completely without contact.

Nach dem Zurückschieben der Programmierspule aus der Meßstellung, kann dann das Geschoß zur Weiterführung aus der Geschoßhaltegabel nach oben herausgeklappt werden. Bei kürzeren Geschossen, deren Geschoßspitze beim in die Klappschale eingelegten Zustand einen größeren Abstand von der Programmierstation aufweist, wird zunächst die Programmierspule zusammen mit der Geschoßhaltegabel auf das Geschoß zubewegt, bis die Geschoßhaltegabel an einer festgelegten Stelle des Geschosses anliegt und somit fixiert ist. Dann wird die Programmierspule in Relativbewegung zur Geschoßhaltegabel weiter in die Meßstellung bewegt.After pushing the programming coil back out of the Measurement position, the floor can then be continued folded out of the projectile holding fork become. In the case of shorter floors, the top of the floor when inserted in the folding tray has a greater distance from the programming station, is the programming coil together with the Projectile holding fork moved towards the projectile until the Projectile holding fork at a fixed point on the Projectile rests and is thus fixed. Then it will be the programming coil in relative movement to the projectile holding fork moved further into the measuring position.

Bei den Relativbewegungen zwischen Programmierspule und Geschoßhaltegabel ist durch den Anschlag ein immer gleichbleibender Abstand zwischen dem Zünder des Geschosses und der Programmierspule sichergestellt und eine Berührung zwischen Zünder und Programmierspule ausgeschlossen.With the relative movements between the programming coil and projectile holding fork is always by the stroke constant distance between the igniter of the Projectile and the programming coil ensured and a contact between the igniter and the programming coil locked out.

  • Fig. 3 in einer Darstellung analog Fig. 1 die Vorrichtung mit in Meßstellung befindlicher Programmierspule.
    • The drawings show:
  • Figure 1 is a partially sectioned axial section of a device for contactless ignition adjustment together with a large caliber projectile in the rest position of the programming coil.
  • Fig. 2 is a section along the line II-II in Fig. 1;
  • Fig. 3 in a representation analogous to Fig. 1, the device with the programming coil in the measuring position.

    • Die in den Fig. 1 bis 3 dargestellte Vorrichtung besitzt eine auf einer horizontalen Grundplatte 2 gelagerte Programmierstation 1, die in axialer Richtung gegenüber einer Klappschale 3 angeordnet ist, in der in strichpunktiert angedeuteter Weise ein großkalibriges langes Geschoß 16 mit einem programmierbaren Zünder 15 oder ein kürzeres Geschoß 18 mit einem Zünder 19 gelagert sind.The device shown in FIGS. 1 to 3 has one mounted on a horizontal base plate 2 Programming station 1 in the axial direction is arranged opposite a folding shell 3, in which a large-caliber one in a dash-dotted manner long floor 16 with a programmable Detonator 15 or a shorter projectile 18 with one detonator 19 are stored.

    An der Programmierstation 1 ist gegen diese in axialer Richtung verschiebbar ein Programmierkopf 7 angeordnet, der als Halterung für eine als Ring- oder Zylinderspule ausgebildete Programmierspule 4 dient. Der Programmierkopf 7 ist an den Enden zweier Führungsstangen 17 befestigt, deren Achsen parallel zueinander in einer die Längsachse des Geschosses 16 enthaltenden horizontalen Ebene liegen und die über Gleitlager 1.1 verschiebbar in der Programmierstation 1 geführt sind. Das Aus- und Einfahren des Programmierkopfes 7 und damit die Bewegung der Programmierspule 4 gegenüber der Programmierstation 1 erfolgt mittels eines Spindelgetriebes. Die Antriebsspindel 10 dieses Spindelgetriebes verläuft parallel zu den Führungsstangen 17. Sie ist an einem Ende über ein Lager 1.2 drehbar in der Programmierstation 1 gelagert und das andere Ende ist an einen nicht dargestellten Elektromotor angeschlossen. Die Spindelmutter 12 des Spindelgetriebes ist jeweils verschiebbar auf den Enden der Führungsstangen 17 verschiebbar gelagert und die kraftschlüssige Verbindung zwischen der Spindelmutter 12 und den Führungsstangen 17 erfolgt jeweils über Druckfedern 11.At the programming station 1 is against this in axial A programming head 7 is arranged to be displaceable in the direction the as a holder for a ring or Cylinder coil designed programming coil 4 is used. The programming head 7 is at the ends of two guide rods 17 attached, the axes of which are parallel to one another in a the longitudinal axis of the projectile 16 containing horizontal plane and the above Slide bearing 1.1 slidable in the programming station 1 are performed. Extending and retracting the programming head 7 and thus the movement of the programming coil 4 compared to programming station 1 by means of a spindle gear. The drive spindle 10 of this spindle gear runs parallel to the Guide rods 17. It is over one end Bearing 1.2 rotatably supported in the programming station 1 and the other end is on one not shown Electric motor connected. The spindle nut 12 of the spindle gear is slidable slidably supported on the ends of the guide rods 17 and the positive connection between the spindle nut 12 and the guide rods 17 each via compression springs 11.

    Vor der dem Geschoß 16 zugewandten Seite der Programmierspule 4 ist eine Geschoßhaltegabel 5 angeordnet, die an ihren Gabelenden schwenkbar angeordnete Geschoßhaltebacken 6 trägt, wobei der Abstand und die Innenkrümmung dieser Geschoßhaltebacken 6 so ausgebildet ist, daß dies dem Geschoßmanteldurchmesser (Ogive) direkt hinter dem Zünder 15 entspricht, so daß das Geschoß 16 an einer vorgegebenen Stelle seines Mantels in der Geschoßhaltegabel fixierbar ist. Damit kann sichergestellt werden, daß die Geschoßspitze und damit der Zünder 15 immer um einen festgelegten Betrag in Richtung auf die Programmierspule 4 über die Geschoßhaltegabel 5 vorsteht.In front of the side of the programming coil facing floor 16 4, a projectile holding fork 5 is arranged, the projectile holding jaws pivotably arranged at their fork ends 6 carries, the distance and the Internal curvature of these projectile holding jaws 6 is formed in this way is that this is the bullet shell diameter (Ogive) directly behind the igniter 15, so that the floor 16 at a predetermined location of his Sheath can be fixed in the storey holding fork. This can ensure that the top of the floor and thus the igniter 15 always around a fixed Amount towards the programming coil 4 protrudes above the projectile holding fork 5.

    Die Geschoßhaltegabel 5 ist an einer Gleitführung befestigt, welche zwei parallel zueinander angeordnete, gleitend durch den Programmierkopf 7 geführte Bolzen 8 aufweist. Die Länge der Bolzen 8 ist so bemessen, daß sie in der in Fig. 3 dargestellten Meßstellung der Programmierspule 4 in Richtung auf die Programmierstation 1 aus dem Programmierkopf 7 austreten, wobei ihre Enden je nach Länge des Geschosses 16 an der gegenüberliegenden Wand der Programmierstation 1 anliegen oder dieser gegenüberliegen. An den den Enden der Bolzen 8 gegenüberliegenden Stellen der Programmierstation 1 sind Dämpfungsvorrichtungen angeordnet, die als federbelastete Stoßdämpfer ausgebildet sind und einen durch eine Druckfeder 9 belasteten Stößel 9.1 besitzen.The projectile holding fork 5 is attached to a sliding guide, which are two parallel to each other, bolts sliding through the programming head 7 8 has. The length of the bolts 8 is dimensioned that they are in the measuring position shown in Fig. 3 the programming coil 4 in the direction of the programming station 1 emerge from the programming head 7, their ends depending on the length of the projectile 16 the opposite wall of the programming station 1 concern or oppose this. At the ends the bolt 8 opposite points of the programming station 1 damping devices are arranged, which are designed as spring-loaded shock absorbers are and loaded by a compression spring 9 Have plunger 9.1.

    Die Bewegung des Programmierkopfes 7 mit der Programmierspule 4 auf die Geschoßhaltegabel 5 zu, erfolgt gegen die Kraft einer Druckfeder 14, die geführt über einen Halterungsbolzen 14.1 zwischen Geschoßhaltegabel 5 und Programmierkopf 7 angeordnet ist.The movement of the programming head 7 with the programming coil 4 to the projectile holding fork 5, takes place against the force of a compression spring 14, which is guided over a mounting bolt 14.1 between the projectile holding fork 5 and programming head 7 is arranged.

    Die Bewegung der Programmierspule 4 auf die Geschoßhaltegabel 5 zu, wird in der Meßstellung begrenzt durch einen an der Geschoßhaltegabel 5 angeordneten Anschlag 13, der mit einem Gegenanschlag 13.1 am Programmierkopf 7 zusammenwirkt.The movement of the programming coil 4 on the projectile holding fork 5 too, is limited in the measuring position by a arranged on the projectile holding fork 5 Stop 13 with a counter stop 13.1 on the programming head 7 interacts.

    Die Wirkungsweise der oben beschriebenen Vorrichtung ist folgende:The operation of the device described above is the following:

    Bei einem langen Geschoß 16 wird in der Ruhestellung von Programmierkopf 7 und Programmierspule 4 (s.Fig. 1) das Geschoß 16 in die Klappschale 3 so eingelegt, daß es an einer vorgegebenen Stelle seines Mantels hinter dem Zünder 15 von den Geschoßhaltebacken 6 der Geschoßhaltegabel 5 umfaßt wird und in dieser Stellung fixiert ist. Wie man aus Fig. 1 erkennt, ist in dieser Stellung der Zünder 15 außerhalb der Programmierspule 4 angeordnet. Nun wird mittels des Spindelantriebs der Programmierkopf 7 aus der in Fig. 1 dargestellten Ruhestellung in die in Fig. 3 dargestellte Meßstellung verschoben, bis Anschlag 13 und Gegenanschlag 13.1 aneinander anliegen. Die Bewegung erfolgt gegen die Kraftwirkung der Druckfeder 14 und unter Zwischenschaltung der Druckfeder 11 des Spindelantriebs. Wie aus Fig. 3 ersichtlich, liegt in der Meßstellung der Zünder 15 innerhalb der Programmierspule 4, die in nicht dargestellter Weise an eine elektrische Steuereinrichtung angeschlossen ist, so daß in dieser Stellung die Einstellung bzw. Programmierung des Zünders 15 erfolgen kann.With a long floor 16 is in the rest position of programming head 7 and programming coil 4 (see Fig. 1) the floor 16 is inserted into the hinged shell 3 so that it is at a predetermined point on its coat behind the igniter 15 from the projectile holding jaws 6 Missile retaining fork 5 is included and in this position is fixed. As can be seen from Fig. 1, is in this position of the igniter 15 outside the programming coil 4 arranged. Now using the spindle drive the programming head 7 from that shown in Fig. 1 Rest position in that shown in Fig. 3 Measuring position shifted until stop 13 and counter stop 13.1 lie against each other. The movement takes place against the force of the compression spring 14 and under Interposition of the compression spring 11 of the spindle drive. 3, is in the measuring position the igniter 15 within the programming coil 4, in an unillustrated manner to an electrical Control device is connected so that in this position the setting or programming the igniter 15 can take place.

    Nach erfolgter Zündereinstellung wird der Programmierkopf 7 wieder in die in Fig. 1 dargestellte Ruhestellung zurückgefahren, in welcher der Zünder 15 außerhalb der Programmierspule 4 liegt und somit das Geschoß 16 nach oben weggeklappt werden kann. Es wird darauf hingewiesen, daß aufgrund dieser Konstruktion das Anfahren des Geschosses 16 durch den Programmierkopf 7 ohne aufwendige Wegsteuerung, wie beispielsweise mittels Drehgeber, Sensorik usw. rein mechanisch geschehen kann und trotzdem die Programmierspule 4 in der Meßstellung immer den gleichen Abstand zur Zündspitze 15 hat. Durch die kraftbeaufschlagten Druckfedern 11 des Spindelantriebs und der Druckfeder 14 zwischen Geschoßhaltegabel 6 und Programmierkopf 7 wird gewährleistet, daß beim Verrutschen des Geschosses 16 keine Relativbewegungen zwischen Programmierspule 4 und Zünder 15 während des Programmiervorganges entstehen können.After the igniter has been set, the programming head 7 again in the rest position shown in Fig. 1 retracted, in which the igniter 15 is outside the programming coil 4 and thus that Floor 16 can be folded up. It will noted that due to this construction the approach to the floor 16 by the programming head 7 without complex path control, such as using a rotary encoder, sensors, etc. purely mechanically can happen and still the programming coil 4 always the same distance in the measuring position to the ignition tip 15. Through the power Compression springs 11 of the spindle drive and the compression spring 14 between projectile holding fork 6 and programming head 7 ensures that when the bullet slips 16 no relative movements between programming coil 4 and igniter 15 during the programming process can arise.

    Durch die Konstruktion ist weiterhin sichergestellt, daß beim Einlegen des Geschosses 16 in die Geschoßhaltegabel 5 keine Kräfte auf Programmierkopf 7 und Programmierspule 4 ausgeübt werden. Beim Einfahren von zu langen oder zu weit nach vorn in die Klappschale 3 eingelegten Geschossen 16, werden die auf die Geschoßhaltegabel 5 wirkenden Kräfte über die Bolzen 8 direkt auf die Dämpfungsvorrichtungen 9-9.1 der Programmierstation 1 übertragen, so daß auf diese Weise keine Belastungen der Programmierspule 4 oder des Zünders 15 auftreten können.The construction also ensures that when inserting the projectile 16 into the projectile holding fork 5 no forces on programming head 7 and Programming coil 4 are exercised. When entering from too long or too far forward into the folding tray 3 inserted floors 16, the on the projectile holding fork 5 acting forces on the Bolt 8 directly on the damping devices 9-9.1 the programming station 1 transmitted so that on this Way no loads on the programming coil 4 or of the igniter 15 can occur.

    Bei einer Einstellung des Zünders 19 eines kürzeren, in die Klappschale eingelegten Geschosses 18, wird der Programmierkopf 7 zusammen mit der Programmierspule 4 und der Geschoßhaltegabel 5 mittels des Spindelantriebs auf das Geschoß zu bewegt, bis die Geschoßhaltegabel 5 mit den Geschoßhaltebacken 6 hinter dem Zünder 19 auf der Ogive des Geschosses 18 anliegt. Dann wird der Programmierkopf 7 zusammen mit der Programmierspule 4 in der bereits beschriebenen Weise relativ zur Geschoßhaltegabel 5 auf das Geschoß zu bewegt, bis er sich, festgelegt durch die Anschläge 13 bzw. 13.1, in der Meßstellung befindet, in der, wie aus den Zeichnungen abzulesen, wiederum der Abstand zwischen Zünder 19 und Programmierspule 4 genau festgelegt ist.When the igniter 19 is set to a shorter, in the hinged shell 18 inserted the programming head 7 together with the programming coil 4 and the projectile holding fork 5 by means of the spindle drive moved towards the projectile until the projectile holding fork 5 with the projectile holding jaws 6 behind the detonator 19 rests on the ogive of the projectile 18. Then the programming head 7 together with the programming coil 4 in that already described Way relative to the projectile holding fork 5 on the floor to move until it moves, set by the stops 13 or 13.1, is in the measuring position in which as can be seen from the drawings, again the distance between detonator 19 and programming coil 4 exactly is set.

    Nach dem Zurückfahren des Programmierkopfes 7 kann auch hier das Geschoß 18 hochgeschwenkt und dem Ansetzvorgang zugeführt werden.After moving back the programming head 7 can here also the floor 18 swung up and the Attachment process are supplied.
