Description

Die Erfindung betrifft ein Spannfutter mit einer Spannpatrone oder Spannbacken, auf die derSpanndruck von einer axial verschiebbaren Spannmuffe mittels einer Gruppe kegeliger Zwischenglieder übertragen wird.The invention relates to a chuck with a collet or Clamping jaws on which the clamping pressure is applied by an axially displaceable clamping sleeve by means of a group of tapered intermediate links is transmitted.

Diese Spannfutter finden überall da Anwendung, wo ein schnelles Spannen von Drehteilen und Stangenmaterial bei stillstehender sowie auch bei laufender Maschine mechanisch oder von Hand erfolgen soll.These chucks are used wherever quick clamping of turned parts and bar material when the machine is at a standstill as well as when the machine is running should be done mechanically or by hand.

Das neue Spannfutter zeichnet sich gegenüber bekannten Futtern dieser Art durch besonders einfache Bauart, durch nur eine Gruppe von Klemmstücken, kurze Baulänge und geringe Reibungsverluste aus, wodurch sich eine erhöhte Spannkraft ergibt.The new chuck differs from known chucks of this Type due to its particularly simple design, due to only one group of clamping pieces, short Overall length and low friction losses, resulting in an increased clamping force results.

Diese Vorteile werden erfindungsgemäß dadurch erreicht, daß als Zwischenglieder sich an den Kegelflächen in der Spannmuffe und außen an der Spannpatrone abstützende, den Kegelflächen angepaßte Druckbacken vorgesehen sind, wobei der Spanndruck auf die Spannbacken oder Spannpatronen durch Verschieben der Spannmuffe in axialer-Richtung zur Wirkung kommt.These advantages are achieved according to the invention in that as intermediate links on the conical surfaces in the clamping sleeve and on the outside of the clamping cartridge, the conical surfaces adapted pressure jaws are provided, the clamping pressure on the clamping jaws or clamping cartridges by moving the clamping sleeve in the axial direction comes into effect.

Die Erfindung ist nachstehend an Hand des in der Zeichnung dargestellten Ausfizhrungsbeispieles erläutert.The invention is illustrated below with reference to that shown in the drawing Ausfizhrungsbeispieles explained.

Fig. i zeigt das Spannfutter im Längsschnitt und Fig. 2 einen Querschnitt durch das Spannfutter längs der Linie II-II in Fig. i.FIG. 1 shows the chuck in longitudinal section and FIG. 2 shows a cross section by the chuck along the line II-II in Fig. i.

Der Futterkörper i ist mit einer Aufnahme 2 für die Spindelnase der Drehbank versehen. Die Führungsschrauben 3,. die in die Nuten 9 der Druckbacken 4 eingreifen; hindern die Druckbacken am Verdrehen und begrenzen deren Bewegung in Richtung auf die Achsmitte beim Wechseln der Spannpatrone 5: Die- Spannmuffe 6 ist mit einer Ringnut 7 versehen. In die Ringnut 7 :greift ein. Gestänge mit geteiltem Ring oder Nutensteinen in bekannter Weise ein, um die Spannmuffe in axialer Richtung zu verschieben. Mit Hilfe der Ringmutter 8 wird die Spannpatrone 5 in Axialrichtung so verschoben, daß sich der Spanndurchmesser vergrößert oder verkleinert. Durch Verschieben der Spannmuffe 6 in Richtung A werden infolge der Steigung B auf der Spannmuffe 6 und den Druckbackert4 die Druckbacken nach der Achsmitte verschoben und das zu bearbeitende Material festgespannt. Durch Verschieben der Spannmuffe in entgegengesetzter Richtung wird das Spannfutter gelöst.The chuck body i is equipped with a receptacle 2 for the spindle nose Provided lathe. The guide screws 3 ,. those in the grooves 9 of the pressure jaws 4 intervene; prevent the pressure jaws from twisting and limit their movement in the direction of the center of the axis when changing the clamping cartridge 5: The clamping sleeve 6 is provided with an annular groove 7. In the annular groove 7: engages. Linkage with split Ring or slot nuts in a known manner around the clamping sleeve in the axial direction to move. With the aid of the ring nut 8, the clamping cartridge 5 is moved in the axial direction shifted so that the clamping diameter increases or decreases. By Moving the clamping sleeve 6 in direction A will be due to the slope B on the Clamping sleeve 6 and the Druckbackert4 moved the pressure jaws to the center of the axis and clamped the material to be processed. By moving the clamping sleeve the chuck is released in the opposite direction.
