<p>An automatic tool changer for a milling machine is disclosed having an endless chain conveyor for tool holder buckets. Tool holder gripping fingers, once engaged with the tool holder, move it in a strictly arcuate path from storage to the operating head of the machine. The buckets have shaped recesses for confining standard tool holders therein, and special shaped wall openings to facilitate tool holder removal when desired. The tool storage housing has a convenient hinged access door, and also a power operated bottom door, the latter being operable during a tool transfer operation, but entirely sheltered by the housing at all times.</p> |
