[Claims for Utility Model Registration] The axis of the main spindle passes through the midpoint of a line segment connecting the axis of the main spindle of the machine tool and the axis of a rotary cutting tool held in a position parallel to the main spindle by a tool holding device. A rotary cutting tool that is attached to the main shaft, the rotary shaft being rotatable around an axis parallel to the center, and a pair of arms extending from the rotary shaft in the radial direction of the rotary shaft in opposite directions. and a tool holding arm that engages with the rotary cutting tools held by the tool holding device from a direction substantially perpendicular to their axes to hold the rotary cutting tools, and the rotation of the pair of tool holding arms By a combination of forward and reverse movement in the shaft axis direction and forward and reverse rotation around the rotary shaft axis, the rotary cutting tool is removed from the main spindle and returned to the tool holding device, and at the same time, the rotary cutting tool is removed from the tool holding device. In an automatic tool changer that takes out another rotary cutting tool and attaches it to the main shaft, a roller gear is attached to the rotary shaft so as not to be relatively rotatable, and a rotary drive device is connected to a cam that meshes with the roller gear, and the cam has a shape When the cam rotates once, the pair of tool holding arms rotate from the standby position by a certain angle in the positive direction and engage with the rotary cutting tools held by the main shaft and the tool holding device, respectively. After the rotary cutting tools are removed from the spindle and the tool holding device, they are further rotated 180 degrees in the forward direction, and after the rotating cutting tools are inserted into the spindle and the tool holding device, they are rotated in the opposite direction by the predetermined angle and the A cam-type automatic tool changer characterized by having a shape that provides a movement to return to a standby position.
