Abstract
A machine tool includes a rotation indexing device. The rotation indexing device includes a frame accommodates a rotary shaft, a drive motor rotationally drives the rotary shaft, a drive transmission mechanism accommodated in a space inside the frame, and a detection device. The drive transmission mechanism includes a gear mechanism, and the space includes one or more storage parts for storing lubricating oil. The detection device detects a height position of an oil level of the lubricating oil, and is provided on a one-to-one basis with respect to a detection target storage part, which is set as a detection target, of the one or more storage parts.
Claims3
A machine tool comprising:
- a rotation indexing device configured to index an angular position of a rotation target member attached to an end portion of a rotary shaft, the rotation indexing device including:
- a frame configured to accommodate the rotary shaft in a state of rotatably supporting the rotary shaft;
- a drive motor configured to rotationally drive the rotary shaft;
- a drive transmission mechanism accommodated in a space inside the frame and configured to transmit rotation of an output shaft of the drive motor to the rotary shaft, the drive transmission mechanism including a gear mechanism, the space including one or more storage parts configured to store lubricating oil for lubricating at least the gear mechanism;
- and
- a detection device configured to detect a height position of an oil level of the lubricating oil stored in the one or more storage parts, and being provided on a one-to-one basis with respect to a detection target storage part, which is set as a detection target, of the one or more storage parts.
