Claims

[Scope of claims for utility model registration] 1. A movable body that holds the workpiece W or the processing tool 19 (
4, etc.) is slidably supported on a sliding guide (2, etc.), and static pressure by pressure oil 15 is applied between the movable body 4, etc. and the sliding guide (2, etc.), Drive means 1
6 and 17 move the movable body (4 etc.) to the sliding guide body (2
etc.), the driving means 16 is provided between the sliding guide (2, etc.) and the movable body (4, etc.) when the static pressure is applied.
. 2 The holding mechanism includes a clamped holding plate 21 extending along the sliding direction of the movable body (4 etc.), and the clamped holding plate 21.
A holding device for a hydrostatic movable body in a machine tool according to claim 1, characterized in that the holding device comprises holding members 24, 42 that can be held and opened. 3. The clamping member 24 includes a pair of clamping pieces 27 urged in the opening direction by a spring 30, and a manual operation member 29 that closes the clamping pieces 27 against the action of the spring 30. A holding device for a hydrostatic movable body in a machine tool according to claim 2 of the utility model registration claim, characterized in that: 4. The clamping member 42 is comprised of a pair of clamp cylinders 41 disposed opposite to each other on both sides of the clamped plate 21, as set forth in claim (2) of the utility model registration claim. A holding device for static pressure movable bodies in machine tools. 5. Any one of claims 1 to 4 of claims 1 to 4, wherein the movable body includes an X-direction movable body 4, a Y-direction movable body 2, and a Z-direction movable body 46.
A holding device for a static pressure movable body in a machine tool as described in 2.
