Abstract
A rotation table mounted on a machining table of a machine tool includes a clamping mechanism which is driven by air so as to clamp a rotation shaft, and an air purging pressure is applied into a casing so as to prevent a cutting fluid or foreign matter from intruding into the casing of the rotation table. Then, air discharged from the clamping mechanism does not pass through the casing, to which the air purging pressure is applied, and is discharged to the outside of the rotation table through a flow passage.
Claims2
A rotation table comprising:
- a casing;
- a rotation shaft that is rotatably supported by the casing;
- and
- a clamping mechanism that is driven by air so as to clamp the rotation shaft,
- wherein a workpiece is attached to the rotation shaft at one end thereof, and an air purging pressure is applied into the casing so as to prevent a cutting fluid or foreign matter from intruding into the casing, and
- wherein the rotation table further comprises a flow passage that connects the clamping mechanism to the outside of the casing and discharges air discharged from the clamping mechanism to the outside.
3 more elements
A rotation table comprising:
- a first casing;
- a rotation shaft that is rotatably supported by the first casing;
- and
- a clamping mechanism that is driven by air so as to clamp the rotation shaft,
- wherein a workpiece is attached to the rotation shaft at one end thereof, and an air purging pressure is applied into the first casing so as to prevent a cutting fluid or foreign matter from intruding into the first casing,
- wherein the rotation table further comprises a second casing which is provided adjacent to the first casing and to which the air purging pressure is not applied, and the second casing includes a hole communicating to the outside, and
- wherein the rotation table further comprises a flow passage which connects the clamping mechanism to the second casing and discharges air discharged from the clamping mechanism to the second casing.
