Description:

Abstract:

An interchange arm to transfer tools between a tool storage mechanism and a spindle. A pair of the interchange arms are pivoted on rotating shafts of a tool changer mechanism which rotates the arms between the spindle and the tool storage mechanism so that the arms can securely hold and positively locate the tools which are interchanged during the interchange time, and the tool gripping member and locating members are automatically retracted from the tools when the tools are deposited in their respective holding receptacles. A unique gripping arrangement releasably connects the tools to the arm, using a minimal amount of space for getting on and off the tool, and the tool gripping finger mechanisms are self-locking about the tool under the influence of centrifugal force acting on the tool during the interchange interval, to assure a more positive grip on the tool.
