Abstract
Verfahren zum Reinigen von Innenflächen von Gewindebohrungen (2), bei dem ein Reinigungsmedium unter Druck in die Gewindebohrung (2) eingebracht wird, dadurch gekennzeichnet, dass das Reinigungsmedium zumindest im Bereich des Gewindeabschnittes der Gewindebohrung (2) tangential gegen die Wandung des Gewindeabschnittes eingebracht wird.method for cleaning internal surfaces of tapped holes (2), where a cleaning medium under pressure is introduced into the threaded hole (2), characterized that the cleaning medium at least in the region of the threaded portion the threaded bore (2) tangentially against the wall of the threaded portion is introduced.
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Reinigen von Innenflächen von Gewindebohrungen nach den Oberbegriffen der unabhängigen Ansprüche.The The invention relates to a method and a device for cleaning from inside surfaces threaded holes according to the preambles of the independent claims.
Beim Herstellen von Gewindebohrungen in Werkstücken bleiben üblicherweise Rückstände wie beispielsweise Öl oder Späne in den Gewindegängen zurück, welche anschließend aus den Gewindebohrungen entfernt werden müssen. Dies geschieht im einfachsten Fall manuell mittels sogenannten Druckluftpistolen, welche unter hohem Druck stehende Luft in die Gewindebohrung eintreten lassen, um die in den Gewindebohrungen befindlichen Rückstände auszublasen. Es sind jedoch auch lanzenförmige Vorrichtungen bekannt, welche beispielsweise ein flüssiges Reinigungsmedium unter Druck direkt in die Gewindebohrung einströmen lassen, wobei das aus der Gewindebohrung austretende Reinigungsmedium samt eventueller Rückstände abgesaugt wird.At the Making threaded holes in workpieces usually remains Residues such as oil or chips in the threads back, which subsequently must be removed from the threaded holes. This happens in the simplest way Fall manually by means of so-called compressed air pistols, which under let high pressure air enter the threaded hole, to blow out the residues in the threaded holes. It is, however also lance-shaped Devices are known which, for example, a liquid cleaning medium can flow directly into the threaded hole under pressure, with the out of the Threaded hole escaping cleaning medium, including any residues is sucked.
Es hat sich jedoch in der Praxis herausgestellt, dass aufgrund des hohen Druckes des Mediums in der Gewindebohrung sowie aufgrund von Turbulenzen und der Strömungsrichtung der Reinigungsmedien Partikel teilweise sogar noch in Oberflächenvertiefungen der Gewindebohrungen bzw. der Gewindegänge eingedrückt werden, so dass diese Verunreinigungen in den Gewindebohrungen verbleiben oder benachbarte Gewinde verunreinigen. Besonders nachteilig ist dabei, dass, sollten die Verunreinigungen beispielsweise infolge von Vibrationen im Laufe der Zeit aus den Gewindebohrungen gelöst werden, dies zu Funktionsstörungen oder Ausfällen an den Bauteilen führen kann. Bei flüssigen Rückständen wie Öl kann dies dazu führen, dass die Gewindebohrung nicht genügend entfettet ist, was zu einem Loslösen von Schrauben führen kann, falls diese in den Gewinden mittels Klebstoff gesichert sind.It However, it has turned out in practice that due to the high pressure of the medium in the threaded hole and due to Turbulence and the flow direction the cleaning media particles sometimes even in surface depressions the threaded holes or the threads are pressed so that these impurities remain in the threaded holes or contaminate adjacent threads. A particular disadvantage is that, should the impurities for example due to vibrations over time from the Threaded holes are loosened, this to malfunctions or failures lead the components can. In liquid Residues like oil can do this cause that the threaded hole is not sufficiently degreased, resulting in a detachment lead from screws can, if they are secured in the threads by means of adhesive.

der Schrift
Der Erfindung liegt somit die Aufgabe zugrunde, eine Reinigungseinrichtung und ein Verfahren zu schaffen, die eine zuverlässige Reinigung der Gewindegänge ermöglichen. Gelöst wird diese Aufgabe erfindungsgemäß durch die Tangentialkomponente des Reinigungsmediums.Of the Invention is therefore the object of a cleaning device and to provide a method which allows reliable cleaning of the threads. Solved this object is achieved by the tangential component of the cleaning medium.
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Verfahren zum Reinigen von Innenflächen von Gewindebohrungen mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, dass Verunreinigungen zuverlässig aus den Gewindegängen der Gewindebohrungen entfernt werden. Dies wird erfindungsgemäß dadurch erreicht, dass das Reinigungsmedium mit einer tangentialen Richtungskomponente auf die Wandung des Gewindeabschnitts auftrifft, so dass in den Gewindegängen anhaftende Verunreinigungen durch die Tangentialkomponente des Reinigungsmediums sicher von der Wandung losgelöst und nicht in diese hineingedrückt werden.The inventive method for cleaning internal surfaces of threaded holes with the characterizing features of the claim 1 has in contrast the advantage that contaminants reliably from the threads of Tapped holes are removed. This is inventively characterized achieved that the cleaning medium with a tangential directional component impinges on the wall of the threaded portion, so that in the threads adhering impurities by the tangential component of the cleaning medium safely detached from the wall and not pressed into it become.
Eine erfindungsgemäße Vorrichtung zum Reinigen von Innenflächen von Gewindebohrungen mit den kennzeichnenden Merkmalen des unabhängigen Vorrichtungsanspruchs weist eine hohe Reinigungswirkung bei konstruktiv einfachem Aufbau auf.A inventive device for cleaning internal surfaces of threaded holes with the characterizing features of the independent device claim has a high cleaning effect with a structurally simple design on.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sowie der zugehörigen Vorrichtung zum Reinigen von Innenflächen von Gewindebohrungen sind in den jeweils abhängigen Ansprüchen aufgeführt.advantageous Further developments of the method according to the invention and the associated device for cleaning internal surfaces of threaded holes are listed in the respective dependent claims.
