Abstract
A table assembly for a machine tool is provided. The table assembly has a slide, a rotatable table and a table rotation mechanism placed on board the slide and adapted to be driven to rotate the table about a vertical axis. The table rotation mechanism has at least one rotation assembly engaged with a ring gear of the table. The at least one rotation assembly has a torque motor having a vertical motor axis and a reduction gear having an inlet engaged with the torque motor, and an outlet pinion engaged with the ring gear of the table, coaxial to the motor axis. The machine tool is a milling machine or a gantry boring machine.
Claims21
A table assembly for a machine tool, optionally the machine tool being a milling machine or a gantry boring machine, the table assembly comprising a slide translatable on command along a longitudinal axis (X), a table supported by the slide and rotatable with respect to a vertical axis (C), and a table rotation mechanism placed on board the slide and adapted to be driven to rotate the table about the vertical axis (C), wherein the table rotation mechanism comprises at least one rotation assembly engaged with a ring gear of the table and comprising a torque motor having a vertical motor axis and a reduction gear having an inlet, engaged with the torque motor, and an outlet pinion, engaged with the ring gear of the table, coaxial to the motor axis.
A support apparatus for a machine tool comprising:
- at least one table assembly comprising a slide translatable on command along a longitudinal axis (X), a table supported by the slide and rotatable with respect to a vertical axis (C), and a table rotation mechanism placed on board the slide and adapted to be driven to rotate the table about the vertical axis (C), wherein the table rotation mechanism comprises at least one rotation assembly engaged with a ring gear of the table and comprising a torque motor having a vertical motor axis and a reduction gear having an inlet engaged with the torque motor, and an outlet pinion engaged with the ring gear of the table, coaxial to the motor axis;
- and
- a pair of benches supporting the at least one table assembly, wherein each bench of the pair of benches has a main extension along the longitudinal axis (X) and is transversely spaced apart from the other.
