Description

Federbunde für Blattfedern wurden zur Bearbeitung bisher in eine normale Planscheibe mit vier Klauen gespannt und ausgerichtet, oder man spannte die Federbunde zwischen Körner und Mitnehmerscheibe, Bei beiden Arten ist das Ausrichten und Ankörnen sehr zeitraubend, und am fertigen Werkstück zeigen sich hier und da Unregelmäßigkeiten. Es ist an sich bekannt, Werkstücke zwecks Bearbeitung an ihren Stirnflächen durch Zug gegen eine Aufspannfläche zu befestigen. Ebenso ist es bekannt, daß die an der Stirnseite zu bearbeitenden Werkstücke durch Anschläge und Spannteile der Spaniivorrichtung in ihrer Spannlage seitlich und längs genau ausgerichtet und durch eine der Bearbeitungsstelle gegenüberliegende Spannpratze in. der Längsrichtung festgezogen werden. Demgegenüber weist der Erfindungsgegenstand den Vorteil auf, daß das Ausrichten und Festlegen des Werkstückes seitlich und längs nur durch die Form des Aufnahmekopfes der Vorrichtung erreicht wird, d.h. daß das Spannen nur durch Anziehen einer längswirkenden Spannpratze bewirkt wird.Spring collars for leaf springs were previously used in a normal faceplate for processing stretched and aligned with four claws, or the spring bundles were stretched between Center punch and drive plate, both types require a lot of alignment and center punching Time consuming, and the finished workpiece shows irregularities here and there. It is known per se to carry out workpieces for the purpose of machining on their end faces To fasten the train against a mounting surface. It is also known that the at the front Workpieces to be machined by means of stops and clamping parts of the clamping device precisely aligned laterally and longitudinally in their clamping position and in the Be tightened lengthways. In contrast, the subject matter of the invention has the advantage that the alignment and Fixing of the workpiece laterally and lengthways only through the shape of the pick-up head of the device is achieved, i.e. that the tensioning only by tightening a longitudinally acting Clamping claw is effected.

Der Gegenstand der Erfindung stellt eine Spannvorrichtung dar, bei welcher das an seiner Stirnseite zu bearbeitende rahmenartige Werkstück α durch eine innerhalb des Rahmens angreifende Spannpratze c gegen einen am Vorrichtungskörper liegenden, ebenfalls innerhalb des Rahmens angreifenden Spannkopf δ gezogen wird. Dadurch fällt jedes seitliche Ausrichten des Werkstücks fort, und dieses wird in seinen Fertigmaßen genau. Diese Vorzüge gegenüber den bekannten Einrichtungen werden dadurch erzielt, daß durch den den Innenmalßen des Werkstücks (Rahmenweite und -breite) angepaßten Spannkopf b und durch Anziehen der Spannpratze das Werkstück in allen Richtungen festgelegt und ausgerichtet ist. Gegenüber den schon bestehenden Einrichtungen ist gemäß der Erfindung eine Vorrichtung geschaffen, die eine wesentliche Vereinfachung und Verbilligung in der Herstellung der Federbunde zur Folge hat.The subject matter of the invention is a clamping device in which the frame-like workpiece α to be machined on its end face is pulled by a clamping claw c that engages within the frame against a clamping head δ lying on the device body and also engaging within the frame. As a result, there is no need for the workpiece to be aligned laterally, and its finished dimensions are accurate. These advantages over the prior art devices are achieved by b by the Innenmalßen the workpiece (frame length and width) adapted to chuck and is fixed by tightening the clamping jaw, the workpiece in all directions and aligned. Compared to the already existing devices, a device is created according to the invention, which has a significant simplification and cheaper in the production of the spring coils result.
