Claims

[Claims for Utility Model Registration] A tool rest main body that is fixed to a slide that is moved forward and backward along a guide of a machine tool, and a tool rest that is fixedly arranged with respect to the guide near the retreating end position of the slide. The first fixing member and the second fixing member are supported by the tool rest main body to be rotatable around a center line of one rotation and movable between a retracted position and a protruded position along the center line of rotation. a tool holder that is removably fixed to the adapter and holds a plurality of cutting tools at equal angular intervals on a circumference centered on the rotation center line of the adapter; a spring member that biases toward the position, and a positioning mechanism that positions the adapter at a plurality of rotational positions around the rotational center line in the retracted position, and the adapter is immovable relative to the tool rest main body. a clamp mechanism that clamps the slide, and a first actuating member that is actuated by contacting the first fixing member when the slide retreats, and transmits the movement of the moving member of the first actuating member to the clamp mechanism to a clamp release mechanism that releases the positioning of the adapter by the positioning mechanism and causes the adapter to protrude against the biasing force of the spring member to release the clamp on the adapter; and after the clamp release mechanism is activated, the second fixation The second actuating member is actuated by contacting the member, and the movement of the second actuating member is transmitted to the adapter. an adapter rotation drive mechanism that rotates the adapter by an angle equal to the angular spacing of the cutters of the tool holder, while not transmitting movement of the second actuating member in the opposite direction to the adapter when the slide advances. . An index tool rest in which the tool holder rotates when the slide is retreated to a retreating end position, thereby replacing the previously used cutting tool with another cutting tool.
