Description
Die Erfindung betrifft eine Vorrichtung zur Laserbehandlung von zylindrischen Innenflächen, vorzugsweise von Zylinderlaufflächen für Verbrennungsmotoren gemäß dem Oberbegriff des Hauptanspruches.The The invention relates to a device for laser treatment of cylindrical Interior surfaces, preferably of cylinder surfaces for internal combustion engines according to the generic term of the main claim.

Der Zylinder wird mit seiner zylindrischen Innenfläche gedreht und gleichzeitig mit Längs-vorschub axial bewegt, so dass der Hochenergiestrahl sich schraubenförmig mit seinem Auftreffpunkt über die Zylinderinnenfläche bewegt und damit immer vom Rand tiefer liegende Bereiche überstreicht. Nachteilig ist bei solcher Strahlführung, dass nur eine bestimmte Zylindertiefe mit einem günstigen Auftreffwinkel des Strahles überstrichen werden kann. Eine gleichzeitige Anwendung von mehreren Strahlen ist nur über einen schmalen Bereich möglich.Of the Cylinder is rotated with its cylindrical inner surface and at the same time with longitudinal feed moved axially so that the high energy beam is helical with his point of impact over the Cylinder inner surface moves and thus always sweeps from the edge deeper areas. adversely is with such beam guidance, that only a certain cylinder depth with a favorable The angle of incidence of the beam was swept over can be. A simultaneous application of multiple rays is only over a narrow range possible.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung so zu gestalten, dass mehrere Strahlen auf die Laufbahn im Zylinderinneren in einem günstigen Auftreffwinkel gerichtet sein können. Die Intensität von Strahlen soll unterschiedlich dosierbar sein.Of the Invention is based on the object, a generic device To design so that multiple rays on the raceway inside the cylinder in a cheap Impact angle can be addressed. The intensity of rays should be dosed differently.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 erreicht.According to the invention this Task achieved by the features of claim 1.
Danach verfügt die Strahleinheit über einen Träger, der zwei Spiegel aufweist, die ihrerseits im Zylinderraum des Zylinders mit einem bestimmten Radius radial außerhalb der Zylinderachse angeordnet sind. Bevorzugt sind die beiden Spiegel zueinander winkelversetzt vorgesehen. Die Strahlereinheit ist in einer an der Zylinderaufnahme angeordneten Halterung geführt und mit einer Antriebsanordnung für die Einleitung einer Drehbewegung verbunden.After that has the jet unit over a carrier, having two mirrors, in turn, in the cylinder space of the cylinder arranged with a certain radius radially outside the cylinder axis are. Preferably, the two mirrors are angularly offset from each other intended. The radiator unit is in one of the cylinder receptacle arranged bracket out and a drive assembly for initiating rotational movement connected.
In einer anderen erfindungsgemäßen Ausführung ist die Strahlereinheit mit Prismen oder Spiegeln im Zylinderraum des Zylinders auf einer Kreisbahn um die Zylinderachse drehbar und ebenfalls in Richtung der Zylinderachse längs bewegbar eintauchend gehalten und mit einer Antriebsanordnung für seine Drehbewegung auf der Kreisbahn um die Zylinderachse verbunden.In another embodiment of the invention the radiator unit with prisms or mirrors in the cylinder chamber of the Cylinder rotatable on a circular path about the cylinder axis and also in the direction of the cylinder axis along movably immersed and with a drive assembly for his Rotational motion on the circular path connected to the cylinder axis.
