Tool-clamping device

摘要

A clamping device (12) for releasably fastening tool inserts (13), in particular paper-perforator punches and/or paper-perforator dies, to a tool body (5) has a clamping screw (14) accessible from the tool periphery (19) and parallel to the axis of the tool insert (13). The clamping force of the clamping screw (14) is transmitted via a transmission member (15) in the form of a rolling body (16) from a sloping clamping surface (17) to a sloping mating surface (18). This results in a very compact, easily accessible and simple-to-manipulate clamping device (12) clamping reliably with high accuracy. <IMAGE>
