Abstract
A cartridge includes a rotation body, a roller gear cam, a first motor, and a support component. The rotation body is rotatable about a first axis and includes a bearing and a mounting portion on which a table to support a workpiece is configured to be mounted. The roller gear cam is configured to transfer drive power to the bearing to rotate the rotation body about the first axis. The first motor is configured to drive the roller gear cam. The support component supports the rotation body, the roller gear cam, and the first motor. The support component is mountable on a tilt base tiltable about a tilt axis.
Claims15
A cartridge comprising:
- a rotation body rotatable about a first axis and comprising:
- a mounting portion on which a table to support a workpiece is configured to be mounted;
- and
- a bearing;
- a roller gear cam configured to transfer drive power to the bearing to rotate the rotation body about the first axis;
- a first motor configured to drive the roller gear cam;
- and
- a support component that supports the rotation body, the roller gear cam, and the first motor and that is mountable on a tilt base tiltable about a tilt axis.
A table rotator comprising:
- a cartridge;
- and
- a tilt base tiltable about a tilt axis,
- wherein the cartridge comprises
- a rotation body rotatable about a first axis and comprising:
- a mounting portion on which a table to support a workpiece is configured to be mounted;
- and
- a bearing;
- a roller gear cam configured to transfer drive power to the bearing to rotate the rotation body about the first axis,
- a first motor configured to drive the roller gear cam, and
- a support component that supports the rotation body, the roller gear cam, and the first motor and that is mountable on the tilt base,
- wherein the tilt base includes a depressed portion configured to receive the roller gear cam, the first motor, and the rotation body,
- wherein an insertion direction in which the roller gear cam is inserted into the depressed portion is defined as a first direction, and
- wherein the rotation body, the roller gear cam, and the first motor are provided inward of an outer circumferential edge of the support component in a view from a direction along the first direction.
A machine tool comprising:
- a machining head configured to support a tool that is configured to machine a workpiece, the machining head comprising a rotational driver configured to rotate the tool;
- a mover configured to move the machining head relative to the workpiece;
- a table rotator comprising:
- a table configured to support the workpiece;
- a cartridge comprising a first motor;
- a tilt base;
- a support base supporting the tilt base so as to be tiltable;
- and
- a second motor configured to tilt the tilt base about a tilt axis relative to the support base;
- and
- a controller configured to control the rotational driver, the mover, the first motor, and the second motor,
- wherein the cartridge comprises
- a rotation body rotatable about a first axis and comprising:
- a mounting portion on which the table is configured to be mounted;
- and
- a bearing,
- a roller gear cam configured to transfer drive power to the bearing to rotate the rotation body about the first axis,
- the first motor configured to drive the roller gear cam, and
- a support component that supports the rotation body, the roller gear cam, and the first motor and that is mountable on the tilt base,
- wherein the tilt base comprises a depressed portion configured to receive the roller gear cam, the first motor, and the rotation body,
- wherein an insertion direction in which the roller gear cam is inserted into the depressed portion is defined as a first direction, and
- wherein the rotation body, the roller gear cam, and the first motor are provided inward of an outer circumferential edge of the support component in a view from a direction along the first direction.
