Abstract

L'invenzione parte da un procedimento per il serraggio di un pezzo da lavorare dotato di un foro, in cui il pezzo viene sostenuto nella direzione assiale del suo foro e serrato radialmente e da un dispositivo per il serraggio di un pezzo da lavorare, con un foro, con almeno una bussola di serraggio ad azione radiale. Nella lavorazione di un tale pezzo serrato, come nella rettifica, su questo agiscono forze assiali, che devono venire captate in modo sicuro. Per ottenere un appoggio completo del pezzo nei tavoli noti, prima almeno uno dei lati frontali del medesimo deve essere levigato piano in un piano ortogonale al suo asse di simmetria. Per evitare questa fase di lavorazione supplementare, l'invenzione prevede, che il pezzo prima del serraggio radiale venga appoggiato cardanicamente con una delle facce frontali, rispettivamente che nella zona della bussola di serraggio sia previsto un supporto cardanico per il pezzo, come pure nella posizione di riposo siano previsti nella posizione di esercizio pezzi di app oggio che dopo la centratura di questo e il bloccaggio radiale lo sostengano e ne impediscano il movimento assiale in una direzione.(Figura unica).The invention starts from a process for clamping a work piece equipped with a hole, in which the piece is supported in the axial direction of its hole and clamped radially and from a device for clamping a work piece, with a hole, with at least one radial action clamping bush. In the machining of such a tight workpiece, as in grinding, axial forces act on it, which must be safely captured. In order to obtain a complete support of the piece in the known tables, at least one of the front sides of the same must first be smoothed in a plane orthogonal to its axis of symmetry. To avoid this additional processing step, the invention provides that the piece before the radial clamping is cardanically supported with one of the front faces, respectively that in the area of the clamping bush there is a cardanic support for the piece, as well as in the position In the operating position, pieces of support are provided that after centering this and the radial locking support it and prevent its axial movement in one direction. (Single figure).
