Chucking device for tools

摘要

For a tool-chucking device, an existing tool-spindle drive is to be used to produce the axially acting chucking force. The spindle drive acts on a drive spindle (4) which is mounted in the tool-mounting bore (1) and produces a relative movement between a chucking nut (11) and pressure pieces (14) as long as a coupling bolt (17) is actuated. The pressure pieces (14) adjust chucking elements (10) which can be adapted to the tool shank (8) to be chucked. <IMAGE>
