Machine tool with automatic tool changer and tool holder - has tool chuck on tool holder and tool transfer mechanism to preset tool change position

摘要

The tool transfer mechanism (16, 18) has a gripper (26) with two jaws engaging the tool clamping section. An actuator (22, 24) moves the tool holder (14) and the transfer mechanism towards and away from each other orthogonally to the axis of the held tool (40, 42). The axes of the tool and transfer mechanism are parallel. There is a movement conversion mechanism (32) of the mutual motion of the gripper and transfer mechanism near the tool change position for the tool release from the holder. A second relative motion away from each other provides the tool clamping into the holder. The gripper jaws are so shaped as to provide reliable gripping of the tool clamping section. ADVANTAGE - Simple design, and reliable operation.
