Abstract
There is provided a punch tool lift spindle. More specifically, in one embodiment, a punching machine including a tool bearing, a drive spindle coupled to the tool bearing, and a drive system configured to move the tool bearing axially along a lifting axis and to rotate the tool bearing about the lifting axis, the drive system including a motor system comprising a stator and a rotor internally coupled to the stator and a spindle nut coupled to the rotor and cooperating with the drive spindle, wherein the spindle nut is at least partially disposed within the stator.
Claims13
A punching machine comprising:
- a tool bearing;
- a drive spindle coupled to the tool bearing;
- and
- a drive system configured to move the tool bearing axially along a lifting axis and to rotate the tool bearing about the lifting axis, the drive system comprising:
- a motor system comprising a stator and a rotor internally coupled to the stator;
- and
- a spindle nut coupled to the rotor and cooperating with the drive spindle, wherein the spindle nut is at least partially disposed within the stator.
A punching machine comprising:
- a tool bearing;
- a drive system configured to move the tool bearing axially along a lifting axis and to rotate the tool bearing about the lifting axis, the drive system comprising:
- a motor system comprising a stator and a rotor internally coupled to the stator;
- and
- a drive element coupled to the rotor and configured to transmit rotary movement from the rotor to the tool bearing, wherein the torque drive element is at least partially disposed within the stator.
A punching machine comprising:
- a tool bearing;
- a drive system configured to move the tool bearing axially along a lifting axis and to rotate the tool bearing about the lifting axis, the drive system comprising:
- a motor comprising a first stator and a first rotor internally coupled to the first stator;
- and
- a driving element engageable with the motor, wherein the driving element is configured to prevent rotation of the tool bearing about the lifting axis when the driving element is disengaged with the motor, such that the tool bearing is configured to move axially along the lifting axis without rotation when the driving element is disengaged with the motor, and wherein the driving element is configured to rotate the tool bearing about the lifting axis when the driving element is engaged with the motor.
The punching machine of claim 13, comprising a switch arrangement configured to control movement of the driving element.
