Claims

[Claims for Utility Model Registration] (1) A cylindrical tool holder to which a plurality of tool tips are attached, a cylindrical clamper slidably provided in an insertion hole formed on the inner circumference of the tool holder, Three clamp pieces are provided at approximately equal intervals in the circumferential direction and are slidable on an inclined surface formed on the outer periphery of the clamper and whose diameter gradually becomes smaller in the direction of the clamper retraction axis. A tool coupling device comprising: an annular adapter that abuts the outer end surface of the clamp piece and to which a spindle is attached. (2) The tool coupling device according to claim 1, wherein the clamp piece and the clamper are attached by a projection means that fits into a groove means. (3) The groove means has a T-shaped concave cross-sectional shape,
3. The tool coupling device according to claim 2, wherein the protruding means has a T-shaped convex cross-sectional shape. (4) The outer end surface of the clamp piece is a tapered surface having a slight inclination angle with respect to a plane normal to the axis of the clamper, and the inner peripheral surface of the adapter is a fitting surface that abuts the tapered surface. The tool coupling device according to any one of claims 1 to 3, characterized in that it has a groove. (5) The inner circumferential surface of the adapter is in contact with a tapered outer circumferential surface formed on the outer circumference of the tool holder, the diameter of which gradually decreases in the direction of the clamper retraction axis. The tool coupling device according to any one of the above.
