  • Patent number: 4427325
    Abstract: An improved multiple spindle toolhead for a machine tool includes a body having at least one tool-carrying spindle journaled into one side thereof and having an input shaft coupled to the spindle and extending from the body side opposite to the spindle for seating in the machine tool spindle. A plurality of threaded studs extends rearwardly from the body for mating engagement with a plurality of threaded elements seated in the machine tool adjacent to the spindle. Means are provided in the machine tool for rotatably driving the threaded elements relative to the threaded studs on the toolhead body to secure the toolhead against the machine tool.

  • Patent number: 4288909
    Abstract: An automatic tool changer for transferring single tools and/or multiple spindle toolheads between a tool storage magazine and a horizontal spindle of a machine tool. A plurality of single tools and/or toolheads are stored in the tool storage magazine with their shanks in a vertical position. A first tool change arm transfers a selected tool or toolhead from the storage magazine to a tilt unit which tilts the shank of the tool or toolhead by 90.degree. from a vertical to a horizontal position parallel with the axis of the spindle. A second tool change arm removes the tools or toolheads from the tilt unit and spindle simultaneously, interchanges them, and inserts the interchanged tools or toolheads into the spindle and tilt unit. The tilt unit then tilts by 90.degree. back to the vertical position, and the first tool change arm returns the tool or toolhead in the tilt unit back to the tool storage magazine.

  • Patent number: 4125932
    Abstract: A plurality of multiple spindle toolheads are stored in a carousel-type toolhead magazine on top of a machine tool which includes a toolhead driver for driving any selected one of the toolheads. The toolhead driver is mounted for movement along a Z axis toward and away from a worktable. A rotary toolhead changer arm for transferring toolheads from the toolhead magazine to the toolhead driver and vice versa is mounted on the machine for rotation about an axis which is inclined at an angle of 45.degree. to the Z axis. The toolhead changer arm has two diametrically opposed ends which are each inclined at an angle of 45.degree. to the rotary axis of the toolhead changer arm. Clamps are mounted on both ends of the toolhead changer arm for clamping toolheads thereto. When the toolhead changer arm is rotated through 180.degree.
