Description

Spritzvorrichtung sprayer
Beschreibungdescription
Die Erfindung betrifft eine Spritzvorrichtung mit einem Gehäuse und einem Düsenkopf, wobei der Düsenkopf über ein Befestigungsmittel in unterschiedlichen Stellungen an dem Gehäuse anbringbar ist.The invention relates to a spray device with a housing and a nozzle head, wherein the nozzle head is attachable via a fastening means in different positions on the housing.
Derartige Spritzvorrichtungen kommen beispielsweise zum Lackieren von Fahrzeugteilen oder Möbeln zum Einsatz. Dabei befindet sich üblicherweise die Spritzvorrichtung am Ende eines Roboterarmes. Der Düsenkopf unterliegt während des Betriebes jedoch einem gewissen Verschleiß und muss daher regelmäßig ausgetauscht werden. Hierzu wird eine Überwurfmutter von einem Gewindesockel gelöst und der verschlissene Düsenkopf ausgetauscht. Beim erneuten Aufschrauben der Überwurfmutter kommt es immer wieder vor, dass sich der Düsenkopf mitdreht und dadurch die in dem Düsenkopf angeordneten Austrittsöffnungen in einer veränderten Position zu dem Gehäuse ausgerichtet sind. Bei einigen Anwendungen ist es jedoch wichtig, dass der neue Düsenkopf in derselben Position ausgerichtet ist wie der ausgetauschte Düsenkopf.Such spraying devices are used, for example, for painting vehicle parts or furniture. In this case, usually the injection device is located at the end of a robot arm. However, the nozzle head is subject to some wear during operation and must therefore be replaced regularly. For this purpose, a union nut is released from a threaded socket and replaced the worn nozzle head. When the union nut is screwed on again, it happens again and again that the nozzle head also rotates, thereby aligning the outlet openings arranged in the nozzle head in an altered position relative to the housing. In some applications, however, it is important that the new nozzle head is aligned in the same position as the replaced nozzle head.
Aus diesem Grund lag der Erfindung die Aufgabe zugrunde, eine Spritzvorrichtung bereitzustellen, an der ein exaktes Ausrichten eines Düsenkopfes in einer vorgebbaren Position möglich ist.For this reason, the invention has the object to provide a spray device to which an exact alignment of a nozzle head in a predetermined position is possible.
Die Aufgabe wird erfindungsgemäß mit einer Spritzvorrichtung gelöst, bei der an dem Düsenkopf oder dem Gehäuse mindestens ein in axialer Richtung beweglicher und federvorgespannter Fixierstift vorgesehen ist, welcher in einer Raststellung in mindestens eine in dem jeweils anderen Bauteil angeordnete Fixierungsbohrung eingreift. Unter einer Spritzvorrichtung wird ein Spritzapparat oder eine Spritzpistole verstanden. Im Innern der Spritzvorrichtung befindet sich ein Materialkanal mit einer Materialnadel, die mit einer Materialaustrittsdüse zusammenwirkt. Die Materialnadel ist in axialer Richtung verstellbar, so dass die Materialmenge, die aus der Materialaustrittsdüse austritt, gesteuert werden kann. Vorzugsweise ist die Materialaustrittsdüse eine Ringdüse, so dass ein kreisförmiger Materialstrahl erzeugt wird.The object is achieved with a spray device in which at least one axially movable and spring-biased fixing pin is provided on the nozzle head or the housing, which engages in a locking position in at least one arranged in the respective other component fixing bore. A spray device is understood to be a spray gun or a spray gun. In the interior of the spray device is a material channel with a material needle, which interacts with a material outlet nozzle. The material needle is adjustable in the axial direction, so that the amount of material that emerges from the material outlet nozzle, can be controlled. Preferably, the material discharge nozzle is an annular nozzle, so that a circular stream of material is generated.
Nach dem Wechsel des Düsenkopfes wird zunächst die Befestigungsvorrichtung, beispielsweise eine Überwurfmutter, nicht vollständig angezogen, so dass zwischen dem Düsenkopf und dem Gehäuse weiterhin eine Relativbewegung möglich ist und durch Drehen des Düsenkopfes der federvorgespannte Fixierstift in die mindestens eine Fixierungsbohrung eingreift. Sofern mehrere Fixierungsbohrungen vorhanden sind, greift der Fixierstift bei einem Weiterdrehen nacheinander in die einzelnen Fixierungsbohrungen ein. Die Raststellungen sind dann jedoch von dem Bediener wahrnehmbar. Dieser braucht sich bei der Demontage nur ungefähr die Stellung des Düsenkopfes zu merken und erreicht diese exakt in der Raststellung.After changing the nozzle head, first the fastening device, such as a union nut, not fully tightened, so that between the nozzle head and the housing further relative movement is possible and engages by rotating the nozzle head of the spring-biased fixing pin in the at least one fixing hole. If several fixing holes are present, the fixing pin engages in successive rotation in the individual fixing holes. However, the detent positions are then perceived by the operator. This needs to remember during disassembly only about the position of the nozzle head and reaches it exactly in the locked position.
Vorzugsweise sind der Fixierstift in dem Gehäuse und die mindestens eine Fixierungsbohrung in dem Düsenkopf angeordnet. Diese Ausführungsform hat den Vorteil, dass der Düsenkopf als Verschleißteil häufiger ausgetauscht werden muss und daher die einfach einzubringende Fixierungsbohrung trägt, während der Fixierstift zusammen mit einer Druckfeder das aufwendiger herzustellende Bauteil darstellt und demzufolge an dem Gehäuse angeordnet ist. Darüber hinaus benötigt der lateral bewegliche Fixierstift deutlich mehr Bauraum, welcher im Düsenkopf kaum vorhanden ist. Vorteilhafterweise ist das Befestigungsmittel eine den Düsenkopf übergreifende Überwurfmutter, welche in Wirkeingriff mit einem Gewindesockel des Gehäuses bringbar ist. Nach Erreichen der Raststellung wird der Düsenkopf durch weiteres Drehen der Überwurfmutter drehfest mit dem Spritzautomaten verbunden, ohne dass ein Verstellen des mittels Fixierstift und Fixierungsbohrung gehaltenen Düsenkopfes erfolgt.Preferably, the fixing pin in the housing and the at least one fixing hole are arranged in the nozzle head. This embodiment has the advantage that the nozzle head has to be replaced more frequently as a wearing part and therefore carries the fixing hole to be introduced simply, while the fixing pin, together with a compression spring, represents the component which is more complex to manufacture and is therefore arranged on the housing. In addition, the laterally movable fixing pin requires significantly more space, which is barely present in the nozzle head. Advantageously, the fastening means is a nozzle head cross-cap nut, which can be brought into operative engagement with a threaded socket of the housing. After reaching the detent position, the nozzle head is rotatably connected by further rotation of the union nut with the automatic spray gun without an adjustment of the held by means of fixing pin and fixing hole nozzle head.
Es hat sich auch als günstig erwiesen, wenn der Fixierstift in einer Führungsbohrung gelagert ist, welche in axialer Erstreckung des Gehäuses der Spritzvorrichtung und/oder des Düsenkopfes ausgerichtet ist. Die Fixierungsbohrung nimmt sowohl den Fixierstift als auch ein druckbelastetes Federelement auf. Dazu sollte die Führungsbohrung eine größere axiale Länge aufweisen als der Fixierstift.It has also proven to be advantageous if the fixing pin is mounted in a guide bore, which is aligned in the axial extent of the housing of the spray device and / or the nozzle head. The fixing hole receives both the fixing pin and a pressure-loaded spring element. For this purpose, the guide bore should have a greater axial length than the fixing pin.
Besonders bevorzugt ist der Fixierstift an mindestens einem Ende mit einer Kuppe ausgebildet. Die Kuppe sollte aus der Führungsbohrung vorstehen, sich beispielsweise an dem Düsenkopf abstützen und bei Erreichen der Raststellung in die entsprechende Fixierungsbohrung eintauchen. Für den Fall, dass der Düsenkopf über die erste Rastposition hinaus in eine weitere Rastposition gedreht werden soll, erleichtert die Kuppenform des Fixierstiftes ein Herauswandern und Zurückgleiten des Fixierstiftes aus der Fixierungsbohrung.Particularly preferably, the fixing pin is formed on at least one end with a dome. The dome should protrude from the guide bore, for example, be supported on the nozzle head and immerse in reaching the detent position in the corresponding fixing hole. In the event that the nozzle head is to be rotated beyond the first detent position into a further detent position, the dome shape of the locating pin facilitates outward movement and sliding back of the locating pin from the fixation bore.
Beim Anziehen der Überwurfmutter kann es vorkommen, dass der Düsenkopf versehentlich mitbewegt wird und er somit seine vorgesehene Position verlässt. Es muss daher gewährleistet sein, dass dann, wenn die gewünschte Position des Düsenkopfes eingestellt ist, diese Mitnahme verhindert wird. Um dies zu gewährleisten, weist die Kuppe vorzugsweise einen Ausschnitt mit einer Kuppenkante auf. Die Kuppenkante hat den Vorteil, dass sie im Zusammenwirken mit einer entsprechenden Fläche der Fixierungsbohrung eine Sperrwirkung entfaltet, so - A -When tightening the nut, it may happen that the nozzle head is accidentally moved and thus he leaves his intended position. It must therefore be ensured that when the desired position of the nozzle head is set, this entrainment is prevented. To ensure this, the dome preferably has a cutout with a dome edge. The dome edge has the advantage that it unfolds in conjunction with a corresponding surface of the fixing hole a blocking effect, so - A -
dass ein Verdrehen des Spritzkopfes in Drehrichtung der Überwurfmutter beim Anziehen wirksam verhindert werden kann.that a rotation of the spray head in the direction of rotation of the nut when tightening can be effectively prevented.
Der Ausschnitt macht weniger als 50% des Kuppenvolumens aus. Dies bedeutet, dass mindestens der Scheitel der Kuppenfläche, insbesondere der Kugelfläche, die die Kuppenfläche bildet, enthalten bleibt. Dies hat den Vorteil, dass die Kuppe beim Weiterdrehen des Düsenkopfes mit einer runden Fläche an der ebenen Unterseite des Düsenkopfes anliegt. Die gegenüber dem Scheitel der Kuppe zurückgesetzte Kuppenkante kann die Auflagefläche des Düsenkopfes dadurch nicht beschädigen.The cutout accounts for less than 50% of the dome volume. This means that at least the apex of the tip surface, in particular the spherical surface which forms the tip surface, remains contained. This has the advantage that the dome rests on further rotation of the nozzle head with a round surface on the flat bottom of the nozzle head. The set against the crest of the dome top edge can not damage the support surface of the nozzle head.
Vorzugsweise ist der Fixierstift gegen Verdrehen gesichert. Damit wird gewährleistet, dass die Kuppenkante in der vorgesehenen Ausrichtung verbleibt und die Sperrwirkung immer bezüglich derselben Bewegungsrichtung auftritt.Preferably, the fixing pin is secured against rotation. This ensures that the dome edge remains in the intended orientation and the blocking effect always occurs with respect to the same direction of movement.
Gemäß einer vorteilhaften Ausgestaltung weist der Fixierstift mindestens einen axialen Abschnitt mit einer radialen Ausnehmung auf. Darüber hinaus ist vorzugsweise in dem Gehäuse eine Bohrung eingebracht, welche mit der Führungsbohrung eine Ebene aufspannt und diese trifft. In die Bohrung kann eine Fixierschraube derart eingesetzt sein, dass diese in oder durch die Ausnehmung des Fixierstiftes ragt. Der Verfahrweg des Fixierstiftes wird durch die Ausnehmung und die dadurch verlaufende beziehungsweise hineinragende Fixierschraube begrenzt. In einer ausgeschobenen Stellung des Fixierstiftes drückt das Federelement den Fixierstift innerhalb der Fixierungsbohrung nach vorne. Dadurch wandert die Ausnehmung ebenfalls nach vorne, bis das Ende der Ausnehmung gegen die Fixierschraube stößt und dadurch ein weiteres Herausschieben des federvorgespannten Fixierstiftes verhindert wird. Außerdem wird ein Verdrehen des Fixierstiftes verhindert. Vorteilhafterweise weist die mindestens eine Fixierungsbohrung einen Innendurchmesser auf, der geringfügig größer als der Außendurchmesser des Fixierstiftes ist, so dass dieser von der Fixierungsbohrung aufgenommen werden kann.According to an advantageous embodiment, the fixing pin has at least one axial section with a radial recess. In addition, a bore is preferably introduced in the housing, which spans a plane with the guide bore and hits it. In the bore, a fixing screw may be inserted such that it protrudes into or through the recess of the fixing pin. The travel of the fixing pin is limited by the recess and thereby extending or projecting fixing screw. In an extended position of the fixing pin, the spring element presses the fixing pin within the fixing hole to the front. As a result, the recess also moves forward until the end of the recess abuts against the fixing screw and thereby further pushing out of the spring-biased fixing pin is prevented. In addition, a rotation of the fixing pin is prevented. Advantageously, the at least one fixing bore has an inner diameter which is slightly larger than the outer diameter of the fixing pin, so that it can be received by the fixing hole.
In einer günstigen Ausführungsform bilden mehrere Fixierungsbohrungen einen Lockkreis, wobei der Lockkreis stets der Führungsbohrung gegenübersteht. Um die gängigen Positionen einzustellen, kann der Lockkreis beispielsweise fünf Fixierungsbohrungen in einer Ausrichtung von jeweils 45° zueinander umfassen.In a favorable embodiment, a plurality of fixing holes form a lock circle, the lock circle always facing the guide hole. In order to adjust the usual positions, the lock circle may, for example, comprise five fixing holes in an orientation of 45 ° to each other.
Die Fixierungsbohrungen können auf der Unterseite eines Befestigungsflansches des Düsenkopfes angeordnet sein. Der Befestigungsflansch stellt eine ringförmige ebene Fläche dar und kommt bei einem aufgesetzten Düsenkopf vorzugsweise auf dem Gewindesockel des Gehäuses zur Auflage.The fixing holes can be arranged on the underside of a mounting flange of the nozzle head. The mounting flange is an annular flat surface and comes with an attached nozzle head preferably on the threaded base of the housing for support.
Vorzugsweise ist die Fixierungsbohrung eine Sackbohrung, die in eine Bewegungsrichtung des Düsenkopfes mindestens eine zur Achse des Fixierstiftes geneigte Fläche aufweist.Preferably, the fixing hole is a blind bore, which has at least one inclined surface to the axis of the fixing pin in a direction of movement of the nozzle head.
Der Fixierstift ist derart in der Führungsbohrung festgelegt, dass die Kuppenkante an der geneigten Fläche anliegt und auf diese Weise in der vorgesehenen Bewegungsrichtung ihre Sperrwirkung entfaltet.The fixing pin is fixed in the guide bore in such a way that the tip edge rests against the inclined surface and in this way unfolds its blocking action in the intended direction of movement.
Vorzugsweise weist der Düsenkopf eine Materialaustrittsdüse auf. Diese Materialaustrittsdüse erzeugt vorzugsweise einen Rundstrahl. Als Material wird vorzugsweise ein Beschichtungsmaterial zum Beschichten von Substraten verwendet. Vorzugsweise weist der Düsenkopf seitlich der Materialaustrittsdüse mindestens ein Hörn mit mindestens einer Luftdüse auf. Es ist bevorzugt, mindestens zwei gegenüberliegende Hörner vorzusehen.Preferably, the nozzle head has a material outlet nozzle. This material outlet nozzle preferably produces an omnidirectional jet. The material used is preferably a coating material for coating substrates. The nozzle head preferably has at least one horn with at least one air nozzle laterally of the material outlet nozzle. It is preferred to provide at least two opposing horns.

Die Figur 1 zeigt eine teilweise geschnittene perspektivische Ansicht einer Spritzvorrichtung 2 mit einem Gehäuse 19 und mit einem über ein Befestigungsmittel 3 daran befestigten Düsenkopf 1. Die Spritzvorrichtung 2 weist ein im Wesentlichen quaderförmiges Gehäuse 19 auf, in welchem unter anderem eine in einem Materialkanal 20 angeordnete Materialnadel 16 und weitere nicht näher gezeigte Druckleitungen und Stelleinrichtungen zur Versorgung mit Druckluft und Material untergebracht sind.1 shows a partially cutaway perspective view of a spray device 2 with a housing 19 and a nozzle head 1 attached thereto via a fastening means 3. The spray device 2 has a substantially parallelepipedal housing 19 in which inter alia one disposed in a material channel 20 Material needle 16 and other pressure lines not shown in detail and Actuators are accommodated for the supply of compressed air and material.
An dem Düsenkopf 1 ist in einem mittigen Bereich eine Materialaustrittsdüse 15 zu erkennen, aus welcher das zu verspritzende Beschich- tungsmaterial austritt. In einem äußeren Randbereich ist die Materialaustrittsdüse 15 von zwei gegenüberliegenden Hörnern 17 umgeben, von denen in der Darstellung der Figur 1 lediglich ein Hörn 17 zu erkennen ist. In den Hörnern 17 befindet sich jeweils mindestens eine Luftdüse 18, aus der Druckluft austritt, mit der die Geometrie des Be- schichtungsmaterialstrahis beeinflusst werden kann. Der Materialstrahl besitzt beispielsweise einen runden Querschnitt (Rundstrahl) und kann durch die aus den Luftdüsen ausströmende Luft zu einem Flachstrahl verändert werden. Um ein zu lackierendes Werkstück mit einem dafür ausgerichteten Materialstrahl zu treffen, ist es von großer Wichtigkeit, auch nach einem Abnehmen des Düsenkopfes 1 diesen wieder in der ursprünglichen Ausrichtung auf dem Gehäuse 19 anzubringen.On the nozzle head 1, a material outlet nozzle 15 can be seen in a central region, from which the coating material to be sprayed emerges. In an outer edge region, the material outlet nozzle 15 is surrounded by two opposing horns 17, of which only one horn 17 can be seen in the illustration of FIG. In each of the horns 17 there is at least one air nozzle 18, from which compressed air emerges, with which the geometry of the coating material radiation can be influenced. The material jet has, for example, a round cross-section (round jet) and can be changed to a flat jet by the air flowing out of the air nozzles. In order to strike a workpiece to be coated with a material beam aligned therewith, it is of great importance, even after a removal of the nozzle head 1, to mount it again in the original orientation on the housing 19.
Das Befestigungsmittel 3 umfasst eine Überwurfmutter 6, welche konzentrisch auf einen mit einem Außengewinde versehenen Gewindesockel 7 aufgedreht wird. Zunächst wird die Überwurfmutter 6 jedoch nicht vollständig angezogen, sondern nur so weit, dass sich der Düsenkopf 1 noch weiterhin gegenüber dem Gehäuse 19 drehen und dadurch in der vorgesehenen Stellung justieren lässt.The fastening means 3 comprises a union nut 6, which is turned concentrically onto a threaded socket 7 provided with an external thread. First, however, the nut 6 is not fully tightened, but only so far that the nozzle head 1 still continue to rotate relative to the housing 19 and thereby adjust in the intended position.
Das Justieren erfolgt mittels eines Fixierstiftes 4, der in seiner axialen Richtung beweglich in einer Führungsbohrung 8 gehalten ist. Bei einem abgenommenen Düsenkopf 1 ragt der Fixierstift 4 aufgrund eines ebenfalls in die Führungsbohrung 8 eingelegten Federelementes 14 aus der Führungsbohrung 8 heraus. Nach dem Aufsetzen des Düsenkopfes 1 wird der Fixierstift 4 durch den Befestigungsflansch 13 des Düsenkopfs 1 in die Führungsbohrung 8 zurückgedrückt. Bei einer Drehung des Du- senkopfes 1 gleitet der Fixierstift 4 bis zum Erreichen einer ersten Fixierungsbohrung 5 mit seinem vorderen Ende an dem Befestigungsflansch 13 entlang. Nach Erreichen der ersten Fixierungsbohrung 5 taucht der Fixierstift 4 aufgrund der Federkraft des Federelementes 14 in die Fixierungsbohrung 5 ein und verrastet dadurch den Düsenkopf 1 an dem Gehäuse 19. In der Ausführung der Figur 1 befinden sich innerhalb des Befestigungsflansches 13 noch weitere in Umfangsrichtung zueinander beabstandete Fixierungsbohrungen 5.The adjustment takes place by means of a fixing pin 4, which is held in its axial direction movable in a guide bore 8. With a removed nozzle head 1, the fixing pin 4 projects out of the guide bore 8 due to a spring element 14, which is likewise inserted in the guide bore 8. After placing the nozzle head 1, the fixing pin 4 is pushed back through the mounting flange 13 of the nozzle head 1 in the guide bore 8. Upon rotation of the duplex senkopfes 1 slides the fixing pin 4 until it reaches a first fixing hole 5 with its front end to the mounting flange 13 along. After reaching the first fixing hole 5 of the fixing pin 4 dives into the fixing hole 5 due to the spring force of the spring element 14 and thereby locks the nozzle head 1 to the housing 19. In the embodiment of Figure 1 are within the mounting flange 13 further spaced apart in the circumferential direction Fixing holes 5.
Sofern eine andere Raststellung gewünscht ist, muss der Bediener den Düsenkopf 1 gegen den Widerstand des vorstehenden Fixierstiftes 4 weiter drehen. Der Fixierstift 4 gleitet dann in der Führungsbohrung 8 zurück, so dass sich der Düsenkopf 1 weiter drehen lässt. Das Herausschieben des Fixierstiftes 4 aus der Fixierungsbohrung 5 wird insbesondere durch eine an dem vorderen Ende ausgebildete Kuppe 9 möglich, die besonders gut in Figur 3 zu erkennen ist.If another detent position is desired, the operator must continue to rotate the nozzle head 1 against the resistance of the protruding fixing pin 4. The fixing pin 4 then slides back in the guide bore 8, so that the nozzle head 1 can continue to rotate. The pushing out of the fixing pin 4 from the fixing hole 5 is possible in particular by a formed at the front end tip 9, which can be seen particularly well in Figure 3.
Die Figur 2 zeigt einen Querschnitt durch die Spritzvorrichtung 2 mit einem daran angeschraubten Düsenkopf 1 , wobei die in Zusammenhang mit der Figur 1 beschriebenen Hörner 17 aufgrund der Wahl der Schnittebene nicht sichtbar sind.FIG. 2 shows a cross-section through the spray device 2 with a nozzle head 1 screwed thereto, wherein the horns 17 described in connection with FIG. 1 are not visible due to the choice of the cutting plane.
Damit das Federelement 14 bei abgenommenem Düsenkopf 1 nicht den Fixierstift 8 vollständig aus der Führungsbohrung 8 schiebt, wurde von der Oberseite des Gehäuses 19 eine rechtwinklig zu der Führungsbohrung 8 verlaufende weitere Bohrung 11 eingebracht. Diese Bohrung 11 läuft durch die Führungsbohrung 8, wobei in die Bohrung 11 eine Fixierschraube 12 eingesetzt ist, deren Länge wiederum über die Führungsbohrung 8 hinaus reicht.So that the spring element 14 does not push the fixing pin 8 completely out of the guide bore 8 when the nozzle head 1 is removed, a further bore 11 extending at right angles to the guide bore 8 has been introduced from the upper side of the housing 19. This bore 11 passes through the guide bore 8, wherein in the bore 11 a fixing screw 12 is inserted, the length of which in turn extends beyond the guide bore 8 also.
Wie in Figur 3 zu erkennen ist, weist der Fixierstift 4 in diesem Bereich eine Ausnehmung 10 auf, durch welche die Fixierschraube 12 hindurch reicht und dadurch den Fixierstift 4 in Position hält. Durch das Zusammenspiel von Ausnehmung 10 und Fixierschraube 12 ist lediglich eine begrenzte axiale Bewegung des Fixierstiftes 4 möglich, jedoch keine Drehbewegung um die eigene Achse.As can be seen in FIG. 3, the fixing pin 4 has a recess 10 in this area, through which the fixing screw 12 passes extends and thereby holds the fixing pin 4 in position. Due to the interplay of recess 10 and fixing screw 12 only a limited axial movement of the fixing pin 4 is possible, but no rotational movement about its own axis.
Die Einschränkung der Drehbewegung ist insbesondere von Vorteil, wenn, wie in Figur 3 dargestellt, ein Fixierstift 4 mit einer ausgeschnittenen Kuppe 9 verwendet wird. Diese weist eine Kugelfläche 9' und eine stufenartige Seite auf und sorgt dafür, dass der Düsenkopf 1 in einer bevorzugten Drehrichtung leicht weiter gedreht werden kann und in der entgegen gesetzten Richtung gesperrt ist.The restriction of the rotational movement is particularly advantageous if, as shown in Figure 3, a fixing pin 4 is used with a cut-out point 9. This has a spherical surface 9 'and a step-like side and ensures that the nozzle head 1 can be easily rotated in a preferred direction of rotation and locked in the opposite direction.
Die stufenartige Seite wird durch den Ausschnitt 30 gebildet, der eine Stirnfläche 33 und eine Seitenfläche 31 aufweist. Die Seitenfläche 31 bildet mit der Kuppe 9 eine Kuppenkante 32. Der Ausschnitt 30 umfasst vorzugsweise weniger als 50% des Volumens der Vollkuppe, so dass die Kante 32 nicht im Scheitel 42 der Kuppe 9 liegt. Die Kuppenkante 32 ist gegenüber dem Scheitel 42 zurückgesetzt.The step-like side is formed by the cutout 30, which has an end face 33 and a side face 31. The side surface 31 forms a dome edge 32 with the dome 9. The cutout 30 preferably comprises less than 50% of the volume of the full dome, so that the edge 32 is not located in the apex 42 of the dome 9. The dome edge 32 is set back relative to the apex 42.
Wie in den Figuren 4 und 5 dargestellt ist, wird die Fixierungsbohrung 5 durch eine Sackbohrung gebildet, die mindestens eine zur Stiftachse 35 geneigte Fläche 40 aufweist, an der die Kante 32 angreift. Bei einer Bewegung in Pfeilrichtung, insbesondere Drehrichtung der Überwurfmutter beim Anziehen, ist der Düsenkopf 1 gesperrt, weil sich die Kante 32 in die geneigte Fläche 40 drückt. In der gezeigten Ausführungsform besitzt die Fixierungsbohrung 5 eine Kegelfläche 40. In entgegengesetzter Richtung ist eine Bewegung des Düsenkopfs 1 möglich, weil die Kugelfläche 9' der Kuppe 9 an der Kegelfläche 40 anliegt, die den Stift 40 verschiebt. Hierbei gleitet die Kugelfläche 9' an der Kegelfläche 40 nach unten. - -As shown in Figures 4 and 5, the fixing hole 5 is formed by a blind bore having at least one inclined to the pin axis 35 surface 40 on which the edge 32 engages. During a movement in the direction of the arrow, in particular the direction of rotation of the union nut when tightening, the nozzle head 1 is locked because the edge 32 presses into the inclined surface 40. In the embodiment shown, the fixing bore 5 has a conical surface 40. In the opposite direction, a movement of the nozzle head 1 is possible because the spherical surface 9 'of the tip 9 abuts the conical surface 40, which moves the pin 40. Here, the spherical surface 9 'slides on the conical surface 40 down. - -
