Abstract
The invention concerns a multi-spindle automatic lathe intended for machining bars of material. Such lathe comprises: a spindle carrier (2) adapted to be displaced in rotation and translation and on which spindles (3) intended for holding bars (M) are assembled together, and bar (M) shaping means including tool bearing carriages (14) which are arranged and adapted in order to receive machining tools (12) and which are directed by control cams (16, 18) supported and driven in rotation, such lathe being characterized in that the shaping means are mounted around a central body (50) which assures the interior guidance of the spindle carrier (2) while the shaping means and the spindles (3) assembled on the spindle carrier (2) are actuated from the exterior by peripheral driving means.
Claims29
A multi-spindle automatic lathe for machining bars of material, said lathe comprising:
- a supporting structure,
- a spindle carrier having a central bore,
- a plurality of spindles for holding bars (M) to be machined, said spindles being supported by said spindle carrier, and
- shaping means for shaping bars (M), said shaping means including tool bearing carriages supporting machining tools and being controlled by cams supported and driven in rotation,
- said lathe being characterized in that said supporting structure comprises a rigid central body and a support shaft extending longitudinally therefrom, said support shaft being immovably fixed relative to said central body, said shaping means being mounted on and around said central body, said support shaft being engaged in said central bore so that said spindle carrier is guided both in rotation and in translation in front of said shaping means by engagement of said support shaft with an interior surface of said spindle carrier bounding said central bore, said shaping means and said spindles being actuated by peripheral driving means surrounding said support shaft.
