Abstract

Die Erfindung betrifft eine Schnellspannvorrichtung (1) zum Spannen von Werkzeugen oder Werkstücken, umfassend wenigstens eine Spanneinheit (9a, 9b) die mittels wenigstens einer Schubkurbel (17a, 18a, 17b, 18b) eines mechanischen Kurbeltriebs zwischen einer lösenden und einer festspannenden Position hin- und herbewegbar (b) ist. Erfindungsgemäß ist vorgesehen, dass zwischen wenigstens einer Spanneinheit (9a; 9b) und wenigstens einer diese bewegende Schubkurbel (17a, 18a; 17b, 18b) wenigstens ein verstellbares Bindeglied angeordnet ist, mittels dessen bei einer vorgegebenen Stellweglänge dieser Spanneinheit (9a; 9b) deren Spannkraft einstellbar ist.The invention relates to a quick-action clamping device (1) for clamping tools or workpieces, comprising at least one tensioning unit (9a, 9b) which moves between a releasing and a tightening position by means of at least one sliding crank (17a, 18a, 17b, 18b). and is movable (b). According to the invention, at least one adjustable link is arranged between at least one tensioning unit (9a; 9b) and at least one sliding crank (17a, 18a, 17b, 18b), by means of which the tensioning unit (9a; Clamping force is adjustable.

Die Erfindung betrifft ferner eine Werkzeugmaschine umfassend eine solche Schnellspannvorrichtung (1).
