Abstract
A tool gripper to remove a tool from and position the tool in a work spindle or a tool magazine, respectively, includes two tong-like gripper arms, a support attached to a tool changer on which the two gripper arms are mutually movably mounted, and an operating device to open and close the two gripper arms. To achieve a simple construction with only a few individual parts, and to avoid technically complicated hydraulic or pneumatic driving mechanisms, according to the invention a first spring is disposed between the two gripper arms to provide a closing force. Further, the support having a bore therein, is motor-driven and movably arranged on a column. A pin inserted in the bore, which is axially parallel to the column, may be shifted against a second spring, and a locking member laterally attached to the bore engages between the rear legs of the two gripper arms.
