Composite machining lathe
First Claim
1. A composite machining lathe comprising:
- a spindle;
a tool magazine;
a tool holder base movable in the direction of an axis of the spindle;
a continuous elongated flexible tool carrier, in said tool magazine, adapted to run along a path having a curved section;
a plurality of tools carried by said tool carrier in such a manner that the shanks of each said tools are located outside of said tool carrier and said shanks on the portion of said tool carrier in said curved section of said path are selectively engageable with a head bore formed in said tool holder base;
means for mounting said tool magazine such that said tool magazine is movable together with said tool holder base in synchronism in the direction of axis of said spindle and in the direction perpendicular to said spindle axis;
means for mounting said tool holder base in such a manner that said tool holder base is movable to and from a retracted position relative to said tool magazine; and
tool holding means, provided on said tool holder base, for holding the tools on said tool carrier by said shanks.

Abstract
A composite machining lathe having a tool holder base movable in the direction of the axis of the spindle and a tool magazine. The tool magazine has a continuous elongated flexible tool carrier adapted to run along a path having a curved section. A plurality of tools are carried by the tool carrier in such a manner that the tools on the portion of the tool carrier in the curved section of the path are selectively engageable with a head bore formed in the tool holder base. The tool magazine is mounted such as to be movable together with the tool holder base in synchronism in the direction of axis of the spindle and in the direction perpendicular to the axis of the spindle. The tool holder base is mounted in such a manner that it is movable to and from a retracted position relatively to the tool magazine. Tool holding means are provided on the tool holder base for holding the tools on the tool carrier. The selected tool to be used in the machining is moved to the curved section of the path of the tool carrier where the distance between adjacent tools is increased to avoid any interference between adjacent tools, while other tools are densely arranged on the straight portion of the tool carrier. The number of tools employed can be increased by the use of a supplementary tool magazine storing a number of tools.

6. A composite machining lathe comprising:
-
a spindle; a tool magazine; a tool holder base movable in the direction of an axis of the spindle; a continuous elongated flexible tool carrier, in said tool magazine, adapted to run along a path having a curved section; a plurality of tools, which include a rotary tool and a turning tool, carried by said tool carrier in such a manner that the shanks of each said tools are located outside of said tool carrier and said shanks on the portion of said tool carrier in said curved section of said path are selectively engageable with a head bore formed in said tool holder base; means for mounting said tool magazine such that said tool magazine is movable together with said tool holder base in synchronism in the direction of an axis of said spindle and in the direction perpendicular to said spindle axis; means for mounting said tool holder base in such a manner that said tool holder base is movable to and from a retracted position relative to said tool magazine; tool holding means, provided on said tool holder base, for holding the tools on said tool carrier by a side portion of said shanks when carried by said tool carrier; and power transmit means, provided on said tool holder base independently from said tool holding means, for transmitting torque to said rotary tool by engaging with said rotary tool when said rotary tool is held by said tool holding means.
