ABSTRACT:
A multi-component chucking system, in particular for concentric or true-rotation tools, has a recieving body (1) optionally having a chucking shaft, with an engagement surface (8) extending at right angles to the axis of rotation (2) and a coaxial retention bore (7) as well as a tool element (9), preferably embodied as a tool holder. On its end face, the tool element also has an engagement surface (11) at right angles to the axis of rotation and is formed with a coaxial retention stub (10) fitting into the retention bore (7), by means of which stub the tool element can be centered with respect to the receiving body. A chucking pin (18) associated with the retention stub and coaxial with the axis of rotation, along with chucking means actuatable from outside the receiving body, allows the clamping together of the tool element and the receiving body. The chucking means have two radially movably supported locking elements (27), which have locking surfaces by which, in a chucking position, wedge-like surface regions (21) of the chucking pin (18 ) that are inclined with respect to the axis of rotation are engaged from below. These wedge-like surface regions of the chucking pin are located on a single common conical surface region that is coaxial with the axis of rotation and forms an acute angle (22) with it.
