DRILLING AUTOMATIC MACHINE TOOL Russian patent published in 2004 - IPC

FIELD: machine engineering, working articles of soft, non-metallic materials, of semi-precious stones.

SUBSTANCE: machine tool includes housing, spindle assembly, motor for driving machine tool mechanism, reduction gear, camshaft. In order to enlarge manufacturing possibilities, to simplify design and to reduce size, machine tool s provided with manipulator having tail spindle and designed for clamping and rotating blank. Gate valve for supplying blanks and feeder are mounted on manipulator. Housing has two floors. Drive motor and camshaft are mounted on lower plate of housing. Main motion motor supporting tool in its shaft is mounted in spindle assembly. Machine tool may have spring for clamping blank. Said spring is arranged outside tail spindle. Unclamping mechanism is in the form of pusher forcing spring at periodical descending caused by movement along cam.
