Abstract

A tool holder with a code carrier and a body member for supporting a tool, said body member being provided with internal threading. A pin is threaded into the internal threading of the body member and serves to secure the tool holder, and the code carrier is arranged upon this pin.

Claims

1. A tool holder comprising an axially extending tool holder body member for holding a tool, said tool holder body member being provided with one end adapted to hold a tool and internal axial threading, an axially extending pin threadably connected with the internal threading of the tool holder body member and serving for the attachment of the tool holder to a tool driving spindle operator, a tool code carrier, said code carrier comprising a sleeve member seated upon said pin, said sleeve member being provided with tangentially directed slots transverse to said axial direction and arranged at diametrically opposite locations above one another at the periphery of the sleeve member, said tool holder body member including a flange adjacent to said tool removable caliper means in engagement with said sleeve and flange for positioning said sleeve member in a predetermined axial and radial direction at the pin with respect to said flange, and means for removably locking said fixed sleeve member in radial and axial direction with respect to the pin.

2. The tool holder as defined in claim 1, wherein said sleeve member is provided with a radially directed threaded bore and a set screw threaded in said bore for securing the sleeve member at the pin.

3. The tool holder as claimed in claim 1, wherein said sleeve and flange are each provided with at least one recess for removably receiving said caliper, said flange is provided with recesses offset through 180* with respect to one another, said caliper serving to align the sleeve member at the pin in radial direction with respect to said recesses and in axial direction with respect to said flange.

4. The tool holder as defined in claim 3, further including a substantially U-shaped fork member having arms, means for scanning the tool holder secured to said arms in confronting relationship to said code carrier, said scanning means comprising measurement value transmitters arranged opposite one another in a plane.
