Abstract
The invention provides a machine tool capable of facilitating a process of switching product ejecting apparatuses. The machine tool comprises a spindle which rotates a workpiece around an axis of the spindle, an actuator which reciprocates a rod arranged parallel to the axis of the spindle, and a coupler switched between a coupling position and a standby position. The coupler connects the rod and an ejecting shaft inserted in the spindle when held in the coupling position. The coupler is not connected to at least the ejecting shaft when held in the standby position. The ejecting shaft along with the coupler is moved in the direction of the axis of the spindle according to reciprocation of the rod when the coupler is held in the coupling position.
Claims8
A machine tool comprising:
- a spindle which rotates a workpiece around an axis of the spindle;
- an actuator which reciprocates a rod arranged parallel to the axis of the spindle;
- a coupler switched between a coupling position and a standby position, the coupler connecting the rod and an ejecting shaft inserted in the spindle when held in the coupling position, and the coupler not being connected to at least the ejecting shaft when held in the standby position;
- and
- a guide shaft arranged parallel to the axis of the spindle and the rod,
- wherein the ejecting shaft along with the coupler is moved in a direction parallel to the axis of the spindle according to reciprocation of the rod when the coupler is held in the coupling position,
- wherein the coupler is provided with a through-hole through which the guide shaft passes, and
- wherein the coupler is moved along the guide shaft in the direction parallel to the axis of the spindle and rotated around the guide shaft to be switched between the coupling position and the standby position.
A machine tool comprising:
- a spindle which rotates a workpiece around an axis of the spindle;
- an actuator which reciprocates a rod arranged parallel to the axis of the spindle;
- a coupler switched between a coupling position and a standby position, the coupler connecting the rod and an ejecting shaft inserted in the spindle when held in the coupling position, and the coupler not being connected to at least the ejecting shaft when held in the standby position;
- and
- a standby position holder arranged on the rear side of the spindle with respect to a direction substantially parallel to the axis of the spindle, the standby position holder having a recess for receiving a part of the coupler to fix the coupler held in the standby position;
- wherein the coupler is pivoted about a pivot axis parallel to the axis of the spindle from the coupling position to the standby position, the pivot axis is located between the axis of the spindle and the rod;
- and
- wherein the ejecting shaft along with the coupler is moved in the direction parallel to the axis of the spindle according to reciprocation of the rod when the coupler is held in the coupling position.
