Description
Die Erfindung betrifft einen Spannkopf, ' insbesondere für Werkzeugmaschinen, der j aus zwei Gruppen radial beweglicher Klemm- | stücke besteht, die durch einen achsial bewegliehen Spannring beeinflußt werden. Die Erfindung besteht aus der in den Ansprüchen näher gekennzeichneten Ausführungsform.The invention relates to a clamping head, 'in particular for machine tools, of the j of two groups of radially movable clamping | pieces that are influenced by an axially movable clamping ring. The invention consists of the embodiment characterized in more detail in the claims.
Der Spannkopf ist auf der Zeichnung durch die Fig. ι bis 3 näher veranschaulicht.The clamping head is illustrated in more detail in the drawing by FIGS.
Fig. ι zeigt einen Längsschnitt durch den Kopf in nicht gesperrter Lage; Fig. 2 zeigt einen Querschnitt; Fig. 3 zeigt den Kopf in gesperrter Lage im Längsschnitt.Fig. Ι shows a longitudinal section through the head in the unlocked position; Fig. 2 shows a cross section; Fig. 3 shows the head in the locked position in a longitudinal section.
Der ganze Spannkopf wird auf die Hohl-The entire clamping head is placed on the hollow
*5 spindel α einer Drehbank aufgeschraubt. Er besteht aus der Hülse c, die mit Öffnungen für kegelförmig zulaufende Klemmstücke d versehen ist. Über dieser Hülse verschiebt sich der Spannring b, der zwei Kegelflächen innen besitzt, deren eine die eine Gruppe d der Klemmstücke d, i, in der Arbeitsstellung des Spannrings dauernd niederdrückt und durch den Spannkopf geschlossen hält, während die andere i den Spannring in seiner wirksamen Stellung sichert.* 5 screwed on spindle α of a lathe. It consists of the sleeve c, which is provided with openings for tapered clamping pieces d . The clamping ring b, which has two conical surfaces inside, moves over this sleeve , one of which permanently depresses one group d of the clamping pieces d, i in the working position of the clamping ring and keeps it closed by the clamping head, while the other i operates the clamping ring in its effective position Secures position.
Das Werkstück h wird im Innern von der Spannhülse g umfaßt, deren kegelförmig verlaufendes rechtes Ende sich gegen die Kegelfläche /\l>. Wird daher die äußere Hülse b aus der Lage Fig. 1 in die Lage Fig. 3 verschoben, so werden die Bolzen rf nach innen gedrückt, und gleichzeitig wird die verschiebbare Hülse e entgegen der Wirkung einer im Innern gelagerten Feder nach links verschol.en. Dadurch wird weiter die Kegelfläche / gegen die längsgeschlitzte federnde Spannhülse g gedrückt, und das Werkstück h wird unverrückbar festgehalten'. Um die Hülse b in der Sperrlage zu sichern, sind in der Hülse c unter Federwirkung stehende Klemmstücke i gelagert, die sich in der Sperrlage gegen Schrägflächen des Spannrings b legen und so ein Lockern der Klemmstücke verhindern. The inside of the workpiece h is encompassed by the clamping sleeve g , the conical right end of which extends against the conical surface / \ l & gt. If, therefore, the outer sleeve b is shifted from the position of FIG. 1 to the position of FIG. 3, the bolts rf are pressed inwards, and at the same time the displaceable sleeve e is locked to the left against the action of a spring mounted inside. As a result, the conical surface / is pressed against the longitudinally slotted resilient clamping sleeve g , and the workpiece h is held immovably. In order to secure the sleeve b in the blocking position, clamping pieces i under spring action are mounted in the sleeve c , which in the blocking position lie against inclined surfaces of the clamping ring b and thus prevent the clamping pieces from loosening.
Beim Verschieben der Hülse & nach links werden die Klemmstücke i nach innen verschoben, so daß der Spannkopf wieder geöffnet werden kann.When the sleeve & is moved to the left, the clamping pieces i are moved inwards so that the clamping head can be opened again.
Es kann bei diesem Spannkopf die Spannhülse g entbehrt werden, indem man statt dieser verschiedene lange Klemmstücke verwendet, die das Arbeitsstück unmittelbar fassen. Die Klemmstücke können als Kugeln ausgebildet sein mit gleichem oder verschiedenem Durchmesser. The clamping sleeve g can be dispensed with in this clamping head by using different long clamping pieces instead, which grasp the work piece directly. The clamping pieces can be designed as balls with the same or different diameters.
