Description

Die Erfindung betrifft ein magnetbetätigbares Ventil, insbesondere Hydraulikventil, nach dem Oberbegriff des Anspruchs 1.The invention relates to a solenoid-operated valve, especially hydraulic valve, according to the generic term of claim 1.

Es ist bekannt, magnetbetätigbare Hydraulikventile, beispielsweise bei Werkzeugmaschinen, einzusetzen. Die Magnetventile übernehemen dabei die Steuerfunktion von an den Werkzeugmaschinen angeordneten Funktionseinrichtungen, beispielsweise seien hier Transportbewegungen oder Klemmfunktionen und ähnliches genannt.It is known to use solenoid-operated hydraulic valves, for example in machine tools. The solenoid valves take on the control function of arranged on the machine tools Functional devices, for example, are here Transport movements or clamping functions and similar called.

Das Ventil weist dazu beidseitig eines Grundkörpers angebrachte Elektromagnete auf, die mit einem innerhalb des Grundkörpers angeordneten Kolben in Wirkverbindung stehen. Je nachdem, welcher der beiden Magnete aktiviert wird, wird über die Magnetkraft der Kolben in die eine oder andere Richtung bewegt und gibt dabei Durchflußöffnungen frei, durch die dann beispielsweise eine Hydraulikflüssigkeit in unterschiedlichen Richtungen fließen kann, die wiederum die Bewegungen der erwähnten Einrichtung durch beispielsweise Kolbenzylindereinheiten bewirkt. Die Elektromagnete werden dabei von einem zentralen Punkt, vorzugsweise einer Bedieneinrichtung gesteuert, wobei jeder der beiden Magnete über eine elektrische Gerätesteckverbindung und dem daran befindlichen elektrischen Verbindungskabel mit der Bedieneinrichtung verbunden ist.For this purpose, the valve has a base body on both sides attached electromagnets with a pistons arranged inside the base body Active connection. Whichever of the two magnets is activated, the Magnetic force of the pistons in one way or another Direction moves and there are flow openings free, through which then, for example Hydraulic fluid in different directions can flow, which in turn the movements the facility mentioned by, for example Piston cylinder units causes. The electromagnets are preferred from a central point an operating device controlled, wherein each of the two magnets via an electrical device connector and what is there electrical connection cable with the control device connected is.

Hierbei ist nachteilig, daß zum Anschalten eines solchen Hydraulikventils zwei Verbindungskabel verlegt werden müssen, die separate Steckverbindungselemente aufweisen und somit einen zusätzlichen Verkabelungsaufwand bei der Installation der Ventile zur Folge haben. Darüber hinaus sind bei zwei Gerätesteckverbindungen zusätzliche Einbaufreiräume vorzusehen.The disadvantage here is that for switching on a such a hydraulic valve laid two connecting cables need to be separate connector elements have and thus an additional Cabling effort when installing the valves have as a consequence. In addition, there are two Device plug connections additional installation space to provide.

Aus der FR-A-2 617 565 geht ein Ventil gemäß Oberbegriff des Anspruchs 1 hervor, das auf gegenüberliegenden Seiten seines Grundkörpers jeweils einen Elektromagneten aufweist. An den Elektromagneten sind stiftartige Elektroanschlüsse senkrecht zur Längserstreckung des Grundkörpers angeordnet, die in Aufnahmen eines ölführende Kanäle aufweisenden Anschlußsteckers eintreten. Nachteilig ist, daß das Ventil ein hohe Fertigungsgenauigkeit erfordert, um eine Gegenüberlage der Anschlüsse der Elektromagnete mit den Aufnahmen des Anschlußstekkers, aufgrund der Längentolerenzen der einzelnen Bauteile, sicherzustellen. Ferner sind Wartungs- oder Austauscharbeiten am Ventil mit hohem Aufwand verbunden, da durch die ölführenden Kanäle Hydraulikflüssigkeit austreten kann.FR-A-2 617 565 discloses a valve according to the preamble of claim 1, which on opposite sides of its body each has an electromagnet. To the Electromagnets are pin-like electrical connections arranged perpendicular to the longitudinal extent of the base body, the in recordings of an oil-carrying channel having the connecting plug. Disadvantageous is that the valve has high manufacturing accuracy required to juxtapose the connectors of the Electromagnets with the receptacles of the connector, due to the length tolerances of each Components. Furthermore, maintenance or replacement work on the valve with great effort connected because hydraulic fluid through the oil-carrying channels can leak.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der Anschlußstecker an zwei aneinander gegenüberliegenden Seiten mit Steckkontakten versehen, zwischen den Elektromagneten angeordnet und -bei Fixierung der Elektromagnete an dem Grundkörpervon an axialen Stirnflächen der Elektromagnete positionierten, in die Steckkontakte eingreifenden Kontaktstiften lagefixiert und mit den Elektromagneten elektrisch verbunden ist.According to the invention, the object is achieved by that the connector on two opposite one another Sides with plug contacts, arranged between the electromagnets and -be Fixing the electromagnets on the base body of positioned on axial end faces of the electromagnets, engaging in the plug contacts Contact pins fixed in position and with the electromagnets is electrically connected.

Durch die gefundene Lösung wird vorteilhafterweise erreicht, daß ein magnetbetätigbares Ventil, insbesondere Hydraulikventil, das zwei Elektromagnete aufweist, die einen in einem Grundkörper geführten Kolben in verschiedene Schaltstellungen führen können, somit über nur ein Kabel angeschlossen und gesteuert werden kann. Hierdurch wird erreicht, daß beide Magnete über einen Anschlußstecker angesteuert werden können, der mit nur einem Kabel mit einer Bedieneinrichtung verbunden ist.The solution found is advantageous achieved that a solenoid operated valve, in particular Hydraulic valve, the two electromagnets has a guided in a base body Can lead pistons to different switching positions, thus connected and controlled via only one cable can be. This ensures that both magnets controlled via a connector can be the one with only one cable with one Operating device is connected.

Das Ventil zeichnet sich insbesondere durch einen einfachen und montagefreundlichen Aufbau aus. Durch die Kontaktstifte der Elektromagnete wird bei deren anlegen gleichzeitig eine Halterung für den Anschlußstecker realisiert. Somit wird die Anordnung zusätzlicher Steckverbinder bzw. -verteiler vermieden.The valve is characterized in particular by a simple and easy to assemble. By the contact pins of the electromagnets will be at their simultaneously create a holder for the connector realized. Thus the arrangement additional connectors or distributors avoided.

Indem der Anschlußstecker vorteilhafterweise in das gesamte Ventil formschlüssig integriert wird, ergeben sich im späteren Einsatzfall, beispielsweise beim Einbau in Werkzeugmaschinen, verbesserte Einbaubedingungen, da weniger Einbauplatz benötigt wird.By the connector advantageously in the entire valve is positively integrated, result in later use, for example when installing in machine tools, improved installation conditions, because less installation space is required becomes.

In vorteilhafter Weise ist vorgesehen, daß der Anschlußstecker als separate Einheit ausgebildet ist und außerdem, vorzugsweise oberhalb, des Grundkörpers des Ventils angeordnet ist. Durch die separate Ausbildung des Anschlußsteckers wird vorteilhafterweise erreicht, daß bereits eine Vorverkabelung mit dem Anschlußkabel und der Steckeinrichtung durchgeführt werden kann und das dann anzuschließende Magnetventil später komplettiert werden kann. It is advantageously provided that the connector is designed as a separate unit and also, preferably above, the base body of the valve is arranged. Through the separate Training of the connector is advantageous achieved that a pre-wiring with the connection cable and the connector and the solenoid valve to be connected can be completed later.

Im Sinne der Erfindung ist weiterhin, daß der Anschlußstecker integrierte Leuchtdioden aufweist, die beispielsweise den aktuellen Schaltzustand des Magnetventils anzeigen. Damit kann erreicht werden, daß von einer Bedienperson sofort erkannt werden kann, ob das Magnetventil sich beispielsweise in einer Öffnungs- oder Schließstellung befindet, wobei den beidseitig anliegenden Magneten die jeweilige Stellung vorher zugeordnet werden muß.In the sense of the invention is further that the Connector has integrated light-emitting diodes, which, for example, the current switching state of the Show solenoid valve. This can be achieved that are immediately recognized by an operator can, for example, whether the solenoid valve is in is in an open or closed position, with the magnets on both sides each position must be assigned beforehand.

Darüber hinaus ist vorteilhafterweise möglich, in den Anschlußstecker einen integrierten Schaltleistungsverstärker und/oder einen integrierten Proportionalventilverstärker anzuordnen. Somit kann vorteilhafterweise erreicht werden, daß auch über eine geringe zur Verfügung stehende Schaltleistung die Magnete direkt geschaltet werden können.In addition, it is advantageously possible in the connector an integrated switching power amplifier and / or an integrated Proportional valve amplifier to be arranged. So can advantageously be achieved that also over a low switching power available the magnets can be switched directly.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den in den Unteransprüchen aufgeführten Maßnahmen.Further advantageous embodiments of the invention result from the in the subclaims measures listed.

Im montierten Zustand greifen die Kontaktstifte 24 der Elektromagnete 14 und 16 in die Steckkontakte 22 des Anschlußsteckers 18 ein. Durch diese elektrische Kontaktierung wird gleichzeitig die mechanische Lagefixierung des Anschlußsteckers 18 realisiert. Die Elektromagnete 14 und 16 sind spiegelbildlich identisch aufgebaut. Sie weisen eine Spule 30 auf, die einen Anker 32 umschließt. Der Anker 32 ist gegen die Kraft eines Rückstellgliedes, vorzugsweise einer Feder 34, in axialer Richtung bewegbar.In the assembled state, the contact pins 24 engage the electromagnets 14 and 16 in the plug contacts 22 of the connector 18 a.

Das elektromagnetische Ventil übt folgende Funktion aus, wobei sich bei der Erläuterung der eigentlichen Ventilwirkung nur auf das Wesentlichste beschränkt wird.The electromagnetic valve has the following function from, with the explanation of the actual Valve action only in the most essential is restricted.

Indem der Anschlußstecker 18 über das Anschlußkabel 20 mit einem, hier nicht dargestellten, Schalter aufweisenden Bedienpult verbunden wird, ist im fertigmontierten Zustand durch die Kontaktstifte 24 bzw. Steckkontakte 22 eine elektrisch leitende Verbindung zwischen den auf dem Bedienpult angeordneten Schaltern und den Elektromagneten 14 und 16 hergestellt. Je nachdem welche Bedienfunktion mit dem Ventil 10 bewirkt werden soll, wird die Spule 30 des Elektromagneten 14 oder die Spule 30 des Elektromagneten 16 aktiviert. Die Spule 30 baut dabei ein Magnetfeld auf, welches den innerhalb der Spule geführten Anker 32 axial verschiebt. Durch dieses axiale Verschieben des Ankers 32 wird gleichzeitig der in dem Kanal 25 geführte Kolben 26 axial verschoben. Der Kolben 26 weist dabei derart Durchgangsöffnungen auf, die nach erfolgter axialer Veschiebung einen Kreislauf über den Verbindungskanal 29 mit den Ein- bzw. Auslaßöffnungen 28 schließen.By connecting the connector 18 via the connecting cable 20 with a switch, not shown here having control panel is connected in the fully assembled state through the contact pins 24 or plug contacts 22 an electrically conductive Connection between those arranged on the control panel Switches and the electromagnet 14 and 16 manufactured. Depending on which operating function to be effected with the valve 10, the Coil 30 of electromagnet 14 or coil 30 of the electromagnet 16 activated. The coil 30 builds thereby a magnetic field, which within the Coil guided armature 32 moves axially. By this axial displacement of the armature 32 will at the same time the piston 26 guided in the channel 25 axially shifted. The piston 26 has such Through openings on the axial Shifting a circuit through the connecting channel 29 with the inlet and outlet openings 28 conclude.

Somit wird, je nachdem welcher der Elektromagnete 14 oder 16 aktiviert wird, durch eine entsprechende anders bewirkte axiale Verschiebung des Ankers 32 bzw. des Kolbens 26 ein entgegengesetzter Kreislauf, im Beispiel ein Hydraulikkreislauf, geschlossen.Thus, depending on which of the electromagnets 14 or 16 is activated by a corresponding axial displacement of the armature 32 caused otherwise or the piston 26 an opposite circuit, in the example a hydraulic circuit, closed.

Durch die Gestaltung der an den Elektromagneten 14 und 16 angeformten Bereiche 15 wird eine kompakte Bauform erreicht, die ein platzsparendes Einbauen des gesamten Ventils 10 ermöglicht. Gleichzeitig wird hiermit neben der sicheren elektrischen Kontaktierung eine mechanische Fixierung des Anschlußsteckers 18 erreicht.By designing the electromagnet 14 and 16 molded areas 15 becomes a compact Design achieved that a space-saving installation of the entire valve 10 allows. At the same time is hereby in addition to the safe electrical Contacting a mechanical fixation of the Connector 18 reached.
