Abstract

An automatic tool exchanging machine include a machine body such as gear box, a tool exchanging arm having a tool grasping member and supported by the machine body to be rotatable and to be linearly reciprocally movable in an axial direction of a rotation shaft of the machine body, a rotation drive mechanism provided for the machine body, and a power transmission mechanism for transmitting a driving power of the rotation drive mechanism to the tool exchanging arm. The power transmission mechanism is provided with a motion conversion mechanism for converting a rotational motion of the rotation drive mechanism including servo-motors to a linear reciprocal motion of the tool exchanging arm and the motion conversion mechanism is composed of a feed screw mechanism. The feed screw mechanism is a ball screw mechanism.
