ていることを特徴とする転削工具締結装置。[Claim for Utility Model Registration] An adapter is fixed to the tip of the main spindle of a machine tool, and a protrusion formed on the rear end side of a milling tool is fitted into a through hole formed at the axis of the adapter. At the same time, the milling tool fastening device is configured to attach the milling tool to the machine tool by engaging a flange formed on the outer peripheral surface of the milling tool with a flange portion protruding in the axial direction from the tip of the adapter. The adapter includes a cylindrical adapter body attached to the tip of the spindle of the machine tool, a lock ring attached to the tip side of the adapter body, a clamp bolt for attaching the lock ring to the adapter body, and A clamp bolt mounting hole with a female thread and a pinset bolt mounting hole are formed on the side surface of the adapter body at positions facing each other, and the tip of the adapter body An elastic member is attached to the side to bias the lock ring in the distal direction, and the lock ring has a ring-shaped fitting portion fitted onto the adapter body, and a ring-shaped fitting portion that is fitted onto the adapter body, and a ring-shaped fitting portion that is attached to the lock ring from the inner circumferential surface of the fitting portion. The fitting portion has a flange portion protruding in the axial direction, and a plurality of notches provided in the flange portion, and the fitting portion has a flange portion provided in the clamp bolt mounting hole and a tweezers bolt mounting hole, respectively. A clamp bolt insertion hole and a tweezers bolt insertion hole are formed at corresponding positions and penetrate in the radial direction, and the clamp bolt insertion hole has an inner diameter larger than an outer diameter of the threaded portion of the clamp bolt. It consists of a bolt insertion part and a tapered surface that is continuously formed on the outside of the bolt insertion part, and the outer circumferential surface of the milling tool has a notch corresponding to the notch of the flange part. A flange is provided at a position where the flange is inserted into the notch and has a thickness such that it can be inserted between the rear end surface of the flange portion and the distal end surface of the adapter body as the milling tool rotates. The clamp bolt is screwed into the clamp bolt mounting hole from the clamp bolt insertion hole, and the head of the clamp bolt is in contact with a tapered surface formed in the clamp bolt insertion hole. A milling tool fastening device characterized in that a tapered surface is formed, and the forceps bolt is screwed into a forceps bolt mounting hole from the forceps bolt insertion hole.
