Abstract

Die Erfindung betrifft eine Vorrichtung zum hydromechanischen Polieren der inneren Oberflächen von Werkstücken, die in der Metallurgie, dem Maschinenbau und anderen Gebieten der Technik Anwendung findet. Die Aufgabe der Erfindung ist durch eine Einrichtung gelöst, die zwei Greifmechanismen (5a, 5b) aufweist, in denen die zu bearbeitenden Werkstücke (6) gehalten werden. Die Vorrichtung ist mit einem polierenden Werkzeug (7) ausgerüstet, das mit einer Schmier- und Kühlflüssigkeitsquelle in Verbindung steht. Gemäß der Erfindung wird in jedem der Greifmechanismen (1a, 1b) ein Endstück (2a, 2b) angeordnet. Die Endstücke (2a, 2b) sind im Vorderteil einer speisenden Impulseinrichtung (1a, 1b) ausgebildet. In das eine Ende des zu bearbeitenden Werkstücks (6) wird ein polierendes Werkzeug (7) schwimmend eingeführt. Jeder Greifmechanismus (5a, 5b) ist mit einem mittels eines Ventils (9a, 9b) mit der Schmier- und Kühlflüssigkeitsquelle verbundenen kontaktlosen Geber (8a, 8b) versehen. Das polierende Werkzeug (7) besteht aus einem porös-elastischen Element, auf dessen zylindrischer Oberfläche schraubenförmige Kanäle (12) ausgebildet sind. Das porös-elastische Element (11) ist mit Endstücken (13) versehen, die beweglich in Muffen (14) montiert sind. Die Vorteile der erfindungsgemäßen Vorrichtung bestehen darin, daß die technologischen Möglichkeiten erweitert sind, indem Werkstücke mit langen Öffnungen und mit kleinen Durchmessern der Öffnungen bearbeitet werden können. Dabei wird eine hohe Ebenheitsgüte erreicht. Der Polierprozess verläuft in Öl, wobei eine reichliche Schmierung und eine effektive Wärmeableitung realisiert und die Arbeitsproduktivität gesteigert wird. The invention relates to a device for hydromechanical Polishing the inner surfaces of workpieces made in metallurgy, mechanical engineering and other fields of technology Application. The object of the invention is by a Device solved, which has two gripping mechanisms (5a, 5b) in which the workpieces to be machined (6) are held. The device is equipped with a polishing tool (7), that with a source of lubricant and coolant in Connection is established. According to the invention, in each of the Gripping mechanisms (1a, 1b) an end piece (2a, 2b) arranged. The End pieces (2a, 2b) are in the front part of a feeding Pulse device (1a, 1b) is formed. In one end of the too machining workpiece (6) becomes a polishing tool (7) introduced floating. Each gripping mechanism (5a, 5b) is included one by means of a valve (9a, 9b) with the lubricating and Contactless sensor (8a, 8b) connected to the coolant source Mistake. The polishing Tool (7) consists of a porous-elastic Element with helical channels on the cylindrical surface (12) are formed. The porous-elastic element (11) is provided with end pieces (13) which are movable in sleeves (14) are mounted. The advantages of the device according to the invention are that the technological possibilities are expanded, by workpieces with long openings and small ones Diameters of the openings can be edited. Doing so high level of flatness achieved. The polishing process is ongoing in oil, with plenty of lubrication and effective Realized heat dissipation and increased labor productivity becomes.
