Description
Es ist bekannt, die Spannfutter von Werkzeugmaschinen auf der mit Außengewinde versehenen Arbeitsspindel mittels einer Gegenmutter zu sichern, jedoch. hat die Praxis gezeigt, daß sich die so befestigten. Spannfutter bei schnell umlaufender oder bei Linksdrehung der Arbeitsspindel leicht lösen.It is known to use the chucks of machine tools on the To secure externally threaded work spindle by means of a lock nut, however. Practice has shown that they attached themselves in this way. Chuck with fast rotating or slightly loosen it by turning the work spindle to the left.
Dieser Übelstand wird durch die Sicherungsvorrichtung nach der Erfindung beseitigt, die aus einer radial geschlitzten und mit einer Klemmschraube versehenen Gegenmutter besteht, welche eine Ausbohrung besitzt, die eine auf der Nabe des Futterkörpers angeordnete Sitzfläche umfaßt.This drawback is caused by the safety device according to the invention eliminated from a radially slotted and provided with a clamping screw There is a counter nut which has a bore that is one on the hub of the chuck body arranged seat includes.
Man hat zwar schon Klemmvorrichtungen zum Sichern von Spannfuttern auf Arbeitsspindeln von Werkzeugmaschinen vorgeschlagen, die ein Ablaufen des Futters von der Spindel bei beiden Drehrichtungen verhindern sollen, z. B. in Form eines zwischen den Bund der Maschinenspindel und das Spannfutter einsetzbaren, geteilten Ringes mit hohlkegelig ausgedrehter Stirnfläche für einen Kegelansatz der Spannfutternabe oder auch in Form einer Ringfeder, durch welche eine axiale Verspannung der Befestigungsgewinde erfolgt. Die bekannten Klemmvorrichtungen dieseir Art haben jedoch den Nachteil, daß sie zu großeAbmessungen erfordern und außerdem verhältnismäßig kompliziert und auch zu kostspielig sind. Demgegenüber zeichnet sich die Sicherungsvorrichtung nach der Erfindung durch sehr geringen Raumbedarf sowie durch besondere Einfachheit und Billigkeit aus. Durch den geringen Raumbedarf der Sicherungseinrichtung ist es möglich, die Spannfutter selbst bei ungünstigster Anordnung des Spindelendes mit ausreichender Sicherheit zu befestigen und das Schwung- b.zw. Biegun:gsmoment klein zu halten. Das ist aber für die Rundlaufgenauigkeit der Maschine und die Lebensdauer der Lagerung von ausschlaggebender Bedeutung. In der Zeichnung ist ein. Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig. i eine Stirnansicht der Sicherungsvorrichtung, Fig. 2 einen Schnitt nach der Linie A-B der Fig. i.One already has clamping devices for securing chucks Proposed on work spindles of machine tools that allow the chuck to run off to prevent from the spindle in both directions of rotation, z. B. in the form of a split between the collar of the machine spindle and the chuck Ring with a hollow conical turned end face for a conical shoulder of the chuck hub or in the form of an annular spring, through which an axial bracing of the fastening thread he follows. The known clamping devices of this type, however, have the disadvantage that they require too large dimensions and also relatively complicated and are also too costly. In contrast, the safety device is distinguished the invention by very little space and by particular simplicity and Cheapness out. Due to the small space requirement of the safety device, it is possible even with the most unfavorable arrangement of the spindle end, the chuck has sufficient To attach security and the swing or. Bending: to keep the moment small. But that is for the concentricity of the machine and the service life of the bearings of vital importance. In the drawing is a. Embodiment of the Invention shown. It shows Fig. I an end view of the safety device, Fig. 2 is a section along the line A-B of Fig. I.
Das in bekannter Weise ausgebildete und daher in der Zeichnung nur teilweise angedeutete Spannfutter a ist mit einer Nabe b auf das mit Außengewinde versehene Ende der Arbeitsspindel c aufgeschraubt. Zur Sicherung der Nabe b gegen Lösen .ist erfindungsgemäß die auf das Außengewinde der -Arbeitsspindel aufschraubbare Ringmutter f mit einem radialen Schlitz d versehen. An ihrer der Nabe b zugekehrten- Seite besitzt die Gegenmutter feine Ausbohrung, die eine auf der Nabe b angeordnete ringförmige Sitzfläche k umfaßt. Zum Anziehen der Ringmutter f dient eine Klemmschraube g, durch die die Mutter sowohl auf dem Gewinde der Arbeitsspindel c als auch auf dem Sitz h festgeklemmt. wird. The chuck a , designed in a known manner and therefore only partially indicated in the drawing, is screwed with a hub b onto the end of the work spindle c provided with an external thread. To secure the hub b against loosening. According to the invention, the ring nut f that can be screwed onto the external thread of the working spindle is provided with a radial slot d. On its side facing the hub b, the lock nut has a fine bore which comprises an annular seat surface k arranged on the hub b. A clamping screw g is used to tighten the ring nut f, by means of which the nut is clamped both on the thread of the work spindle c and on the seat h. will.
