Description: |
| Abstract:
An automatic tool changer for a lathe is provided having a rotating drum-type tool storage magazine mounted to the cross slide of the lathe and rotatable to align any one of a plurality of tool holder assemblies and their tools, supported by the magazine, with a guide channel through which a selected tool holder assembly and tool can be slid to the active position, or tool past, on the cross slide, for operating on the workpiece supported by the lathe. A stationary, double-acting, hydraulic piston is disposed in the central portion of the drum-type magazine, having its piston rod in alignment with the guide channel and having a tool holder assembly shuttle member attached to the rod, for transporting an active tool and holder assembly from its ready position in the magazine, in a straight line radially outward from the magazine to the tool post, and for returning the tool holder assembly and tool to their storage position on the magazine after use.
The portion of the term of this patent subsequent to May 25, 1999 has been disclaimed. |
