Abstract
An angle spindle attachment includes a spindle shaft 21 for mounting a tool detachably, a housing 20 for mounting the spindle shaft rotatably such that the spindle shaft is oriented to a different direction with respect to the drive shaft 3 of the spindle unit, a gear train for transmitting the drive power of the spindle unit to the spindle shaft of the angle spindle attachment. a collet means 29 for retaining and releasing the tool that is movable between a position for retaining the tool and a position for releasing the tool so as to interlock the rotation of the spindle shaft, and a switching means 24,16 for switching the collet means between a operative condition to permit the tool to be retained and released and an inoperative condition for mounting the tool undetachably.
Claims6
An angle spindle attachment for a spindle unit of a machine tool that carries out machining in a direction different from a axial direction in which a drive shaft of the spindle unit extends, said attachment comprising:
- a spindle shaft for mounting a tool detachably;
- a housing for mounting the spindle shaft rotatably such that the spindle shaft is oriented to a different direction with respect to the drive shaft of the spindle unit;
- a gear train for transmitting the drive power of the spindle unit to the spindle shaft of the angle spindle attachment;
- a collet means for retaining and releasing the tool that is movable between a position for retaining the tool and a position for releasing the tool so as to interlock the rotation of the spindle shaft;
- and
- a switching means for switching the collet means between a operative condition to permit the tool to be retained or released and an inoperative condition for mounting the tool undetachably.
