Screw head wedge clamp assembly for cutting tool

摘要

A screw head wedge clamp assembly for a cutting tool includes a clamp screw having a screw head with a frustum-shaped portion, and a screw head wedge clamp having a body and a clamp head extending from the body. The clamp head has a frustum-shaped portion that is received in a mounting screw bore of a cutting insert. The wedge clamp contacts a radiused bottom wall of the clamp bore when the clamp screw is threaded into a threaded bore of an insert pocket, thereby causing the clamp head to exert a downward and rearward force against a mounting screw bore of the cutting insert to securely hold the cutting insert in the insert pocket. The screw head wedge clamp does not contact a top surface of the cutting insert, but only the frustum-shaped portion contacts the mounting screw bore of the cutting insert.

主权项

1. A screw head wedge clamp assembly for a cutting tool, comprising:
a clamp screw having a screw head at one end and a threaded body at an opposite end, the screw head having a frustum-shaped portion that is formed at an angle with respect to a central, longitudinal axis of the screw head, the clamp screw capable of being threaded into a threaded bore of an insert pocket of a cutting tool; and a screw head wedge clamp having a body, a clamp head extending from the body and a surface for accommodating the clamp screw, the clamp head having a frustum-shaped portion that is formed at an angle with respect to a central, longitudinal axis of the clamp head, the body of the wedge clamp is capable of being received in a clamp bore of the insert pocket of the cutting tool, wherein the central, longitudinal axis of the screw head is substantially perpendicular to the central, longitudinal axis of the clamp head.
