Description

Kühlmittelpumpe für Werkzeugmaschinen Die heute zum Kühlem des Werkstücks an Werkzeugmaschinen verwendeten Pumpen wirken im der Regel nicht selbstansaugend, benötigen daher ein Fußventil. Wenn, Luft in das Saugrohr emndrimgt, wirdi die Förderung des Kühlmittels unterbundien. Ein weiterer Nachteil der bisher verwendeten Kühlmittelpumpe.n besteht hdarin, daß :sie nur die üblichen Bohrölemulsionen :einwandfrei zu fördern vermögen. Bei Ölen,dagegen, wie sie beispielsweise für viele Arbeiten zu Automaten, Gewindiescbleif-und anderen Werkzeugmaschinen notwendig sind, entstehen bekanntlich ständig Schwierigkeiten, besonders dann, wenn es sich um die Förderung schwerer Schnei,döle handelt. In solch-en Fällen sind,die bekannten Pumpen unzureichend.Coolant pump for machine tools Today for cooling the workpiece Pumps used on machine tools are generally not self-priming, therefore require a foot valve. When air is compressed into the intake manifold, the flow is stopped of the coolant. Another disadvantage of the coolant pump previously used insists that: only the usual drilling oil emulsions: can be conveyed properly capital. In the case of oils, on the other hand, as they are used, for example, for a lot of work on machines, Threaded lead screws and other machine tools are known to arise constant difficulties, especially when the promotion is severe Schnei, döle acts. In such cases, the known pumps are inadequate.

Hinzu kommt, daß es in vielen Fällen erforderlich ist, durch :den Küblflüssigk.ei:tsstrom nicht nur eine: Kühlung der Werkzeugschneiden und des, zu bearbeitenden Werkstücks, .sondern auch gleichzeitig ,die Spanabfuhr zu erzielen. Zu idii@esem IZiweck benötigt man sowohl größere Mengen, Kühlflüs:sigkeit als auch: einen.- entsprechend hohen Druck. In solchen Fällen bedarf es, hhisher in So :uderfertigung erstellter Pumpen größerer Bauart.In addition, in many cases it is necessary by: the Cooling fluid flow is not just one: cooling of the tool cutting edge and the, too machined workpiece, but also to achieve chip evacuation at the same time. For idii @ esem IZiweck you need larger quantities, cooling liquid as well as: a.- correspondingly high pressure. In such cases it is necessary, hitherto in the following way, to manufacture of larger pumps.

Nach der Erfindung werden diese Nachteile behoben, indem als Kühlm:ittelpumpe eine Kugelk.olbenpumpe verwendet wird. Im wesentlichen bestehen, diese Pumpen aus einem kugelförmigen Gehäuse, in dem nein ebenfalls kugelförmiger Kolben vorgesehen ist, der mit zwei, gegenüberliegenden, um 9o° zueinander versetzten Nuten versehen ist, in: welchen je ein Antriebszapfen: und je ein B'lindwellenschieber :gleiten. Antriebswelle und Blindwelle sind: zueinander geneigt. Die Pumpwirkung d@erärtiger Maschinen wird dadurch hervorgerufen, daß beim Drehen der Antriebaweille der von, dem Antriebsschieber mitgenommeneKugelkolben durch die zwangsläufige Nutfüh rumg der zur Antriebswelle geneigt liegenden Welle eine @drehendie und gleichzeitig schwingendie Bewegung ausführt, so daß sich zwischen den Flanken der Schieber einerseitsi und den Flanken der Kwgelkolbennut andererseits Förderkammezn vor den Ein- und Anuslaßöffnungen des Kugelgehäuses mawlartig öffnen, und schließen. Derartige Pumpen, bieten dien: Vorteil, daß sie selbstansaugend! .arbeiten und geigen Lufteinschlüsse unempfindlich sind. Sie haben, einen denkbar geringen Platzbedarf, sind zum Fördern aller für dite Kühlung notwendigen. Kühdm.ittel gleich -gut geeignet und werden bei, denkbar größter Betriebssicherheit allen erforderlichen Drücken gerecht.According to the invention, these disadvantages are eliminated by using a cooling medium pump a ball piston pump is used. Essentially, these pumps consist of a spherical housing in which no spherical piston is also provided which is provided with two opposing grooves offset from one another by 90 ° is, in: each of which a drive journal: and a blind shaft slide each: slide. Drive shaft and jackshaft are: inclined to each other. The pumping action d @ erärtiger Machines is caused by the fact that when the drive shaft is turned, the The ball piston carried along by the drive slide through the inevitable groove guide The shaft, which is inclined to the drive shaft, rotates and swings at the same time Movement executes so that between the flanks of the slide on the one handi and the flanks of the Kwgelkolbennut on the other hand, Förderkammezn in front of the inlet and outlet openings of the ball housing open and close like a mawl. Such pumps provide: Advantage of being self-priming! .work and violin air pockets insensitive are. They have the smallest possible footprint, are all for conveying dite cooling necessary. Coolants are equally suitable and are conceivable with maximum operational safety, meet all required pressures.
