Abstract
A rotatively driveable tool chucking device with at least two chucking disks and a common tightening screw for chucking a tool sleeve between the two chucking disks. The chucking disks have concentric annular grooves for chucking tool sleeves with essentially the same diameter. When the sleeves are of flexible material, they are rotationally stabilized about the central axis of rotation, without requiring a rubber core or similar support body. This stabilization maintains the sleeves always in cylindrical shape.
Claims6
A rotatively driveable tool chucking device comprising at least two chucking disks and a tightening screw extending between the chucking disks, a tool sleeve being chucked between the two chucking disks, the two chucking disks defining concentric annular grooves, the tool sleeve being received without inserting a rubber core in the tool sleeve by the annular grooves, the tool sleeve and the annular grooves having essentially the same diameter and the tool sleeve being of a flexible material, wherein one of the chucking disks has connected thereto axial webs which extend over the tool sleeve and the other chucking disks has recesses for insertion of the ends of the axial webs.
