Description

Die Erfindung betrifft einen Spindelkopf, auch Scheibenkopf genannt, vorwiegend für die keramische Industrie, bei welchem die Spannbacken über Kurven beim Anlaufen der Spindel durch die Beschleunigungskraft selbsttätig geschlossen und beim Stillsetzen der Spindel durch .die Verzögerungskraft selbsttätig wieder geöffnet werden.The invention relates to a spindle head, also called a washer head, mainly for the ceramics industry, in which the clamping jaws over curves automatically closed when the spindle starts up due to the force of acceleration and when the spindle is stopped by .the deceleration force again automatically be opened.

Bei den bisherigen Ausführungen von Scheibenköpfen fehlte teilweise jegliche Spannvorrichtung zum Ausgleich von Durchmessertoleranzen, oder die Spannung mußte durch zusätzliche Handgriffe, verbunden mit Zeitverlust, bewirkt werden.The previous designs of washer heads were partially missing any clamping device to compensate for diameter tolerances, or the tension had to be done by additional manipulations, combined with loss of time.

Bei dem bisher einzigen selbstspannenden Scheibenkopf werden die Spannbacken mittels Fliehgewichte betätigt, hierbei tritt folgender Nachteil auf: Durch exzentrisches Einsetzen des zu spannenden Gutes werden bei Anlage der Spannbacken die Fliehgewichte verschiedene Entfernung von der Spindelachse haben und damit verschiedene Flieh-und Spannkräfte erzeugen, dieses bewirkt ein Verschieben des zu spannenden Gutes bis zu einer festen Anlage.The clamping jaws of the previously only self-clamping washer head operated by means of flyweights, here the following disadvantage occurs: By eccentric The flyweights are inserted when the clamping jaws are in contact with the goods to be clamped have different distances from the spindle axis and thus different fleeing and Generate clamping forces, this causes a displacement of the goods to be clamped up to to a permanent plant.

Diese Nachteile werden bei der vorliegenden Erfindung vermieden. Die Spannung und das Öffnen der Spannbacken erfolgt selbsttätig ohne zusätzliche Handgriffe. Das auf dem Scheibenkopf aufgesetzte Gut wird immer konzentrisch gespannt, da die Spannbacken in jeder Stellung konzentrisch zur Spindelachse stehen.These disadvantages are avoided in the present invention. the The clamping jaws are clamped and opened automatically without any additional hand movements. The goods placed on the disk head are always clamped concentrically because the The clamping jaws are concentric to the spindle axis in every position.

Die Erfindung ist in der Zeichnung veranschaulicht und zeigt Draufsicht, Seitenansicht und Mittelschnitt des Spindelkopfes. Die mit den Kurven i versehene Scheibe 2 wird mittels Gewinde 3 auf die sich in Pfeilrichtung drehende Spindel q. aufgeschraubt.The invention is illustrated in the drawing and shows a plan view, Side view and center section of the spindle head. The one provided with the curves i Disc 2 is screwed onto the spindle rotating in the direction of the arrow by means of thread 3 q. unscrewed.

Die Scheibe 2 trägt über Wälzlager 5 eine weitere Scheibe 6, worauf Backenführungen 7 und Gehäuse 8 befestigt sind. Zwischen den Backenführungen 7, Scheibe 6 und den Deckeln 9, io gleiten die Backen i i, welche mit ihren Verlängerungen 12 und den darauf angeordneten Rollen 13 in die Kurven i der Scheibe 2 hineinragen.The disk 2 carries a further disk 6 via roller bearings 5, whereupon Jaw guides 7 and housing 8 are attached. Between the jaw guides 7, Disc 6 and the covers 9, io slide the jaws i i, which with their extensions 12 and the rollers 13 arranged thereon protrude into the curves i of the disk 2.

Beim Beschleunigen der Spindel q. mit der darauf befestigten Scheibe :2 in Pfeilrichtung vom Stillstand auf die maximale Drehzahl, was in ganz kurzer Zeit geschieht, muß auch die Trägheit der übrigen nur lose aufgesetzten Teile 6, 7, 8, 9, io, 11, 12, 13 des Scheibenkopfes überwunden werden. Die dabei auftretende Beschleunigungskraft bewirkt über die Kurven i-, die Rollen 13 und die Verlängerungen 12 eine Spannkraft in den Backen ii.When accelerating the spindle q. with the disk attached to it : 2 in the direction of the arrow from standstill to maximum speed, which in a very short time Time happens, the inertia of the remaining loosely attached parts 6, 7, 8, 9, io, 11, 12, 13 of the washer head can be overcome. The occurring Accelerating force is effected via the curves i-, the rollers 13 and the extensions 12 a clamping force in the jaws ii.

Beim Stillsetzen der Spindel q. wirkt die Verzögerungskraft in entgegengesetzter Richtung, die Backen ii werden also geöffnet. Die Aussparung 14 dient zum Einsetzen bzw. Herausnehmen des zu spannenden und zu bearbeitenden Gutes.When stopping the spindle q. the retarding force acts in the opposite direction Direction, the jaws ii are opened. The recess 14 is used for insertion or removing the goods to be clamped and processed.
