Automatic tool exchanger for machining center

Abstract

Abstract PURPOSE:To facilitate the exchange of tools, by enabling the separate motion of tool magazines disposed on two levels, and by enabling a tool exchange arm to be turned by 180 deg. and be moved in the direction of the axis of the turning and in a direction perpendicular to the former direction. CONSTITUTION:An upper and a lower magazines 12, 14, in which tools T are housed, are separately rotated around a bearing guide 20 on the top of a frame 19. An arm shaft unit 32 under the piston rod 30 of a fluid pressure unit 28 can be moved up and down. The arm shaft 50 of the unit 32 can be rotated by 180 deg. around the axis of the shaft and be moved in the axial direction. As a result, a tool exchange arm 54 provided at one end of the arm shaft 50 can be turned by 180 deg. and be moved in the direction of the axis of the turning (the axis of the arm shaft 50) or the direction of attachment and detachment of the tools in the axial direction of the piston rod 30. The tools T can thus be moved to the spindle 80 of a machine tool.
