Description

Die Erfindung betrifft einen Stirnmitnehmer für Werkzeugmaschinen@(vor allem für Drehmaschinen) mit besonders großflächiger Lagerung des mit der Zentrierspitze fest verbundenen Gehäuses Der nicht zu übersehende Nachteil aller Systeme ist,'.daß die Zentrierspitze, die von der Rundlaufgenauigkeit dieser Spann-Methode und damit der Genauigkeit des Werkstückes bestimmt wird, eine zu kleine Lagerfläche hat und damit keine stabile und genaue Zentrierung ermöglicht wird. Die Zentriersptzen der bekannten Stirnmitnehmer haben einen zu kleinen Durchmesser der Lagerung, weiche wegen-der um die Zentriersptze angeordneten Mitnehmer-Messer nicht vergrößert werden kann. Diese zu kleine Lagerung wird noch dazu durch den mit dem Kühlwasser eindringenden Schmutz einem raschen. Verschleiß ausgesetzt, Die Zentrierspitze erhält dadurch ein immer größer werdendes Spiel, was zur unerWUnschten Labilität derselben und somit zur untragbaren Ungenauigkeit führt.The invention relates to a face driver for machine tools @ (before especially for lathes) with a particularly large storage area with the center point permanently connected housing The disadvantage of all systems, which cannot be overlooked, is'. that the centering point, which depends on the concentricity of this clamping method and thus the accuracy of the workpiece is determined, has too small a bearing surface and so that no stable and precise centering is possible. The centering points of the known face drivers have too small a bearing diameter, which is soft because of the arranged around the centering knives are not enlarged can. This too small storage is also caused by the penetration with the cooling water Dirt a quick. Exposed to wear, the center point receives an ever-increasing game, which leads to the undesirable instability of the same and thus leads to intolerable inaccuracy.

Der unbrauchbar gewordene bekannte Strnmitnehmer bedarf laufender kostspieliger Instandsetzungen bzw. Austausch seiner teuersten Teile.The known carrier that has become unusable requires ongoing expensive repairs or replacement of its most expensive parts.

Diese Nachteile stellten wir in der Praxis bei-mehreren bekannten Stirnmitnehmernfest. Dadurch wurde die Lösung gefunden., die diese Nachteile beseitigt.We identified these disadvantages in practice with several known ones Face driver fixed. In this way the solution was found which eliminates these disadvantages.

Bei der Erfindung bildet de-Zentrierspitze 1. zusammen mit dem damit Fest verbundenen Gehäuse 2 eine kompakte Einheit 1 + 2..Dieses Gehäuse, weiches- großflächig auf dem Körper 3 gelagert ist, Führt mit der Zentrierspitze 1 die axialen Bewegungen aus. Durch den Druck des Reitstockes wird die Zentrierspitze 1 mit Gehäuse 2 gegen Federdruck 6. soweit zurückgeschoben, daß die im Gehäuse 2 gelagerten und auf einem Ausgleich 5 ruhenden Mitnehmer-Messer 4 beliebiger Zahl zum Eingriff kommen. Die feste Verbindung von Zentrierspitze 1 und Gehäuse 2 lässt das Eindringen .von Wasser und Schmutz nicht zu. und ermöglicht die stabilste Lagerung.In the invention, de-centering point forms 1. together with the with it Permanently connected housing 2 a compact unit 1 + 2..This housing, soft- is mounted over a large area on the body 3, guides with the centering point 1 the axial Movements off. By the pressure of the tailstock becomes the center point 1 with housing 2 pushed back against spring pressure 6th so far that the in housing 2 mounted and on a compensation 5 resting driver knife 4 of any number come to the intervention. The fixed connection of the center point 1 and the housing 2 can the penetration of water and dirt is not blocked. and enables the most stable storage.

Die Summe der Vorteile in der Praxis sind: Langanhaltende Rundlaufgenauigkeit von unter 0,01 mm, höhere Stabilität und dadurch ermöglichte höhere Spanleistung und verminderter Werkzeugverschleiß, Wegfall der Reparaturkosten und Verminderung des Pflegeaufwandes.The sum of the advantages in practice are: Long-lasting concentricity of less than 0.01 mm, higher stability and thus enabled higher cutting performance and reduced tool wear, elimination of repair costs and reduction the maintenance effort.
