Abstract
A jaw exchanger includes a stocker configured to store jaws which are configured to be attached to a chuck body of a machine tool, a stocker movement mechanism configured to move the stocker between a first position and a second position, and a jaw transferor configured to transfer the jaws to the stocker positioned at the first position from a jaw receiver to receive the jaws, and configured to transfer the jaws to the chuck body from the stocker positioned at the second position. The chuck body is rotatable about a rotation axis.
Claims20
A jaw exchanger comprising:
- a stocker configured to store jaws which are configured to be attached to a chuck body of a machine tool, the chuck body being rotatable about a rotation axis;
- a stocker mover configured to move the stocker between a first stocker position and a second stocker position;
- and
- a jaw transferor configured to transfer the jaws from a jaw receiver to the stocker when the stocker is positioned at the first stocker position, and the jaw transferor is configured to transfer the jaws from the stocker to the chuck body when the stocker is positioned at the second stocker position,
- wherein, when the stocker is provided at the first stocker position, the jaw transferor does not overlap the chuck body in plan view, and
- wherein the jaw transferor is mounted on the stocker.
A jaw exchanger comprising:
- a stocker configured to store jaws which are configured to be attached to a chuck body of a machine tool, the chuck body being rotatable about a rotation axis;
- a stocker mover configured to move the stocker between a first position and a second position;
- and
- a jaw transferor configured to transfer the jaws from a jaw receiver to the stocker when the stocker is positioned at the first position, and the jaw transferor is configured to transfer the jaws from the stocker to the chuck body when the stocker is positioned at the second position,
- wherein the chuck body is rotatably supported via a support member, the stocker is provided above the support member in a height direction of the machine tool,
- wherein the stocker is supported by a base not via the support member, the base being provided below the support member in the height direction, and
- wherein the jaw transferor is mounted on the stocker.
A jaw exchanger comprising:
- a stocker configured to store jaws which are configured to be attached to a chuck body of a machine tool, the chuck body being rotatable about a rotation axis;
- a stocker movement mechanism configured to move the stocker between a first position and a second position;
- and
- a jaw transferor configured to transfer the jaws from a jaw receiver to the stocker when the stocker is positioned at the first position, and the jaw transferor is configured to transfer the jaws from the stocker to the chuck body when the stocker is positioned at the second position,
- wherein the stocker movement mechanism comprises a first mover configured to rotate the stocker around a swing axis between a first angle position and a second angle position,
- wherein the first angle position is an angle position where a longitudinal direction of the stocker which passes through the swing axis is inclined relative to the rotation axis, and
- wherein the second angle position is an angle position where the longitudinal direction is substantially parallel to the rotation axis.
