Description
Gebiet der ErfindungField of invention
Die Erfindung bezieht sich auf eine Vorrichtung zum Beschichten einer Zylinderbohrung in einem Kurbelgehäuse für einen Verbrennungsmotor, umfassend eine in die Zylinderbohrung einführbare Beschichtungseinrichtung sowie eine Absaugeinrichtung mittels derer die Zylinderbohrung mit einem axialen Druckgefälle beaufschlagbar ist, wobei die Absaugeinrichtung in Absaugrichtung stromabwärts der Zylinderbohrung ein zur Erzeugung eines Unterdrucks geschaltetes, erstes Gebläse aufweist.The invention relates to a device for coating a cylinder bore in a crankcase for an internal combustion engine, comprising a coating device that can be introduced into the cylinder bore and a suction device, by means of which the cylinder bore can be subjected to an axial pressure gradient, the suction device being used for generation downstream of the cylinder bore in the suction direction having a negative pressure switched, first fan.
Stand der TechnikState of the art
Die
Insbesondere bei größeren Anlagen, bei denen mehrere Kurbelgehäuse unter der Haube auf dem Werktisch Platz finden, sind diese Vorgaben teils schwierig umzusetzen, zumal die konkrete Gestaltung der Haube und der Abluftleitungen zusätzlichen Randbedingungen, die beispielsweise durch die Konstruktion der Gesamtanlage vorgegeben sind, unterworfen sein können.Particularly in larger systems where there is space for several crankcases under the hood on the workbench, these specifications are sometimes difficult to implement, especially since the specific design of the hood and the exhaust ducts may be subject to additional boundary conditions that are specified, for example, by the design of the overall system .
AufgabenstellungTask
Es ist die Aufgabe der vorliegenden Erfindung, eine gattungsgemäße Beschichtungsvorrichtung derart weiterzubilden, dass ein hinreichend starker, gut steuerbarer Luftstrom durch die Zylinderbohrung gewährleistet ist.It is the object of the present invention to develop a generic coating device in such a way that a sufficiently strong, easily controllable air flow through the cylinder bore is ensured.
Darlegung der ErfindungStatement of the invention
Diese Aufgabe wird in Verbindung mit den Merkmalen des Oberbegriffs von Anspruch 1 dadurch gelöst, dass die Absaugeinrichtung in Absaugrichtung stromaufwärts der Zylinderbohrung ein zusätzliches, vom ersten Gebläse verschiedenes, zur Erzeugung eines Überdrucks geschaltetes, zweites Gebläse aufweist.This object is achieved in conjunction with the features of the preamble of claim 1 in that the suction device has an additional second fan, which is different from the first fan and is switched to generate an overpressure, upstream of the cylinder bore in the suction direction.
Bevorzugte Ausführungsformen der Erfindung sind Gegenstand der abhängigen Patentansprüche.Preferred embodiments of the invention are the subject of the dependent claims.
Kerngedanke der Erfindung ist es, zusätzlich zu dem ersten Gebläse, welches stromabwärts der Zylinderbohrung angeordnet ist und dort einen Unterdruck erzeugt, ein zweites Gebläse stromaufwärts der Zylinderbohrung vorzusehen, welches dort einen Überdruck erzeugt bzw. den bereits gegenüber dem vom ersten Gebläse erzeugten Unterdruck bestehenden Überdruck verstärkt. Mit anderen Worten, wird gemäß der vorliegenden Erfindung die Zuluft nicht ausschließlich mittels des ersten Gebläses angesaugt, sondern vielmehr zusätzlich mittels des zweiten Gebläses aktiv eingeblasen. Hierdurch ergibt sich nicht nur die Möglichkeit einer Absolutverstärkung des Luftstroms durch die Zylinderbohrung. Es resultiert auch ein zusätzlicher Steuerungs-Freiheitsgrad, der eine präzisere, bedarfsgerechte Steuerung des jeweils in der aktuell einem Beschichtungsprozess unterworfenen Zylinderbohrung herrschenden Luftstroms erlaubt. Insgesamt lässt sich also eine Verstärkung und Vergleichmäßigung des Luftstroms durch die Zylinderbohrung erzielen.The core idea of the invention is, in addition to the first fan, which is arranged downstream of the cylinder bore and generates a negative pressure there, a second fan upstream of the cylinder bore, which generates an overpressure there or the overpressure that already exists compared to the negative pressure generated by the first fan reinforced. In other words, according to the present invention, the supply air is not sucked in exclusively by means of the first fan, but rather is actively blown in additionally by means of the second fan. This not only results in the possibility of an absolute amplification of the air flow through the cylinder bore. This also results in an additional degree of control freedom which allows a more precise, needs-based control of the air flow prevailing in the cylinder bore currently being subjected to a coating process. Overall, the air flow through the cylinder bore can be amplified and made more even.
Die Erfindung eignet sich insbesondere zur Nachrüstung von Beschichtungsvorrichtungen gemäß Stand der Technik, d.h. von Vorrichtungen, die sich dadurch auszeichnen, dass die Absaugvorrichtung einen von einer Haube überwölbten Werktisch aufweist, der mit wenigstens einem Luftdurchgang versehen ist und auf welchem das Kurbelgehäuse in luftleitender Verbindung der Zylinderbohrung mit dem Luftdurchgang platzierbar ist. Wie oben bereits erwähnt, ist bei solchen Vorrichtungen die Haube ausgangsseitig mit wenigstens einer mit dem ersten Gebläse verbundenen Abluftleitung versehen. Das erfindungsgemäße zweite Gebläse ist bevorzugt mit der Zuluftleitung verbunden, mit der der Luftdurchgang des Werktisches eingangsseitig versehen ist. Insbesondere kann das zweite Gebläse in diese Zuluftleitung integriert sein. Eine solch integrierte Anordnung des insbesondere turbinenartig ausgebildeten Gebläses, die eine besondere Effizienz der Lufteinblasung bewirkt, ist möglich, weil, anders als in der Regel bei dem ersten (Abluft-)Gebläse keinerlei Filter- oder Abscheideelemente zwischen dem Gebläse und der Zylinderbohrung erforderlich sind.The invention is particularly suitable for retrofitting coating devices according to the state of the art, ie devices that are characterized in that the suction device has a workbench vaulted by a hood, which is provided with at least one air passage and on which the crankcase is in air-conducting connection Cylinder bore can be placed with the air passage. As already mentioned above, in such devices the hood is provided on the outlet side with at least one exhaust air line connected to the first fan. The second fan according to the invention is preferably connected to the supply air line with which the air passage of the workbench is provided on the inlet side. In particular, the second fan can be integrated into this supply air line. Such an integrated arrangement The particular turbine-like blower, which causes a particular efficiency of the air injection, is possible because, unlike the first (exhaust) fan, no filter or separation elements are required between the fan and the cylinder bore.
Bei einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die Haube mit wenigstens einer zusätzlichen Zuluftöffnung versehen ist. Eine solche Zuluftöffnung kann zur Steuerung des Unterdrucks in der Haube genutzt werden.In a preferred development of the invention it is provided that the hood is provided with at least one additional air inlet opening. Such a supply air opening can be used to control the negative pressure in the hood.
Wie aus dem Stand der Technik bereits grundsätzlich bekannt, ist die Beschichtungseinrichtung selbst vorzugsweise als eine Plasmabeschichtungseinrichtung ausgebildet. Der Plasmabrenner kann seitlich sowie in der Höhe verfahrbar innerhalb der Haube angeordnet sein und bedarfsweise in die Zylinderbohrung eingeführt und dort bewegt werden. Zum Schutz derjenigen Komponenten des Plasmabrenners, die nicht unmittelbar in die Zylinderbohrung eintauchen, vor Plasmanebel, der durch den Luftstrom aus der Zylinderbohrung gerissen wird, können entsprechende Prallbleche vorgesehen sein.As is already known in principle from the prior art, the coating device itself is preferably designed as a plasma coating device. The plasma torch can be arranged laterally and vertically within the hood and, if necessary, can be introduced into the cylinder bore and moved there. Corresponding baffle plates can be provided to protect those components of the plasma torch that do not immerse directly into the cylinder bore from plasma mist which is torn from the cylinder bore by the air flow.
Die Steuerung des Luftstroms, d.h. insbesondere die Steuerung des erfindungsgemäßen zweiten Gebläses, kann in Abhängigkeit von den jeweils aktuellen Prozessparametern des Beschichtungsprozesses erfolgen.The control of the air flow, i. in particular the control of the second blower according to the invention can take place as a function of the current process parameters of the coating process.
