ABSTRACT:
A tool changer is provided in which a rotary tray positioned beneath the forward edge of a machine tool supports a large number of tools in individual cartridges. A tool changer head includes two outwardly projecting tubular members and can be rotated about a horizontal axis, moved vertically and pivoted about a vertical axis. A vacuum or positive pressure can be generated in the tubular members. Therefore, the tubular members can be positioned over a tool in one of the cartridges after which the tool changer head is raised and rotated to extend the tool into the spindle of a machine tool which has been run past the forward edge of the machine. Negative pressure will withdraw the tool from the cartridge and positive pressure will drive the tool into the spindle. Similarly, a tool can be removed from the spindle by negative pressure and reinserted into the cartridge by positive pressure.
