<p><P>PROBLEM TO BE SOLVED: To provide a tool exchanger for a machine tool capable of making the exchange of a tool quick while a tool exchange cycle time is shortened. <P>SOLUTION: The tool exchanger for a machine tool comprises at least one rotary tool gripper 20, a support 18 for the tool gripper 20 capable of ascending and descending, and turning around a rotary axis 22, and a mechanical type cam drive device having a drive motor 35, a cam barrel 30, and intermediate gears 43-46 and causing a rise and the rotary movement of the tool gripper. The cam barrel 30 has a tappet 34 for rotatably driving the tool gripper 20 at an upper front face, and a cam curve 32 prepared for the ascending movement of the tool gripper 20 on a peripheral surface of the gripper 20. The front tappet 34 drives a Malta gear 40 supported to a shaft 39 parallel to the rotary axis 22 of the tool gripper 20. The Malta gear 40, the cam barrel 30, and the support 18 of the tool gripper 20 are continuously supported in parallel with the axis. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
