油圧シリンダ２６のピストン２７と電動機２８とが設け
られている。A rotary table device using a rotary table as a sliding movable body, which is an example of a sliding movable body support and guide device in the prior art, has a structure as shown in FIG. 3, for example. That is, the annular support 23 is fitted into the outer peripheral groove 22 that is open to the outside and is formed on the outer peripheral surface of the one-turn table 21.
Static pressure pockets 24 are formed on both upper and lower surfaces and the outer peripheral surface of the
A piston 27 of a clamping hydraulic cylinder 26 and an electric motor 28 are provided on a rotating shaft 25 extending downward from the table.

て押圧されてクランプされる。Then, when the electric motor 28 is operated with pressure oil being sent from the hydraulic circuit to the static pressure pocket 24 but not to the clamping hydraulic cylinder 26, the rotary table 21 is supported by the support body 23 under static pressure and is driven to rotate. Ru. On the other hand, if the electric motor 28 is stopped and pressure oil is not sent from the hydraulic circuit to the static pressure pocket 24 but to the clamping hydraulic cylinder 26, the piston 27
Hydraulic pressure acts on the table 21, and the table 21 is pressed and clamped against the upper surface of the support 23.

クランプ時には静圧ポケットから圧油を排出しなければ
ならない。更に、クランプ用油圧シリンダのため装置の
高さ寸法が大きくなる。Conventional technology, such as the rotary table device mentioned above, requires a hydraulic cylinder for clamping, so pressure oil must be supplied and collected separately for the static pressure pocket and the hydraulic cylinder using hydraulic circuits. It's a hassle, but also
Pressure oil must be drained from the static pressure pocket during clamping. Furthermore, the height of the device increases due to the use of a hydraulic cylinder for clamping.

油を供給する給油装置とから構成され、前記給油装置が
両静圧支承面への同時給油と一方の静圧支承面のみへの
給油とに切換自在である。The sliding movable body support guide device according to the present invention includes a fixed support in which two static pressure bearing surfaces facing each other in at least the l@ line direction are formed, and a sliding member supported by static pressure on the static pressure bearing surfaces of the fixed support. It is composed of a sliding sliding body that is displaced and a lubricating device that supplies pressure oil to the opposing hydrostatic bearing surfaces, and the lubricating device can simultaneously lubricate both hydrostatic bearing surfaces or only one of the hydrostatic bearing surfaces. It can be freely switched between refueling and refueling.
摺動移動体の摺動変位に際しては、固定支承体の対向す
る静圧支承面に対し同時に圧油を供給することにより、
摺動移動体を少なくとも静圧支承面に垂直方向の変位を
拘束して両静圧支承面で静圧的に支承案内する。During sliding displacement of the sliding moving body, by simultaneously supplying pressure oil to the opposing static pressure bearing surfaces of the fixed bearing,
The sliding member is statically supported and guided by both hydrostatic bearing surfaces while restraining displacement in the vertical direction at least on the static pressure bearing surface.
摺動移動体を固定支承体に対してクランプするのに際し
ては、一方の静圧支承面への圧油の供給を遮断し、他方

体は、圧油が供給される方の静圧支承面での静圧により
圧油に供給されない方の静圧支承面に押圧される゛結果
、固定支承体にクランプされる。When clamping the sliding member to the fixed support, the supply of pressure oil to one hydrostatic bearing surface is cut off, and pressure oil is supplied only to the other hydrostatic bearing surface. Then, the sliding body is pressed by the static pressure on the hydrostatic bearing surface to which pressure oil is supplied, to the static pressure bearing surface to which pressure oil is not supplied, and as a result, it is clamped to the fixed bearing. .

On the lower end surface of the member 3, there is a static pressure pocket 8 on the lower surface of the rotary table plate 7.
The rotary table 9, in which the first rotary cylinder 5, the second rotary cylinder 6, and the rotary table plate 7 are integrated, faces the upper end surface of the support member 3 on which the rotary cylinder 3 is formed. It is guided and mounted such that it can be rotated about an axis of rotation.

ことは、容易に理解されよう。The above embodiment is a rotary table device, but even in a static pressure guide of a moving body in linear motion, one pressure oil is supplied between the upper and lower static pressure guide surfaces, or between the left and right static pressure guide surfaces. It will be easily understood that the shutoff allows the moving body to be clamped.

にクランプされる。When the encoder 13 detects that the rotary table 9 has rotated by a desired rotation amount, the drive motor 12 is stopped by a control device (not shown), and the rotary table 9 is positioned at a desired position. Thereafter, in the hydraulic circuit, the electromagnetic on-off valve 18 is closed, and pressure oil is supplied from the hydraulic pump 17 to the static pressure pocket 81 and the static pressure pocket 82 via the pipe line Q1 and the pressure oil passage 15a, and the static pressure pocket 83
When pressure oil is not supplied to 6, the second rotary cylinder body 6. In other words, the rotary table 9 is kept in alignment due to the static pressure of the static pressure pocket 81 acting on the outer peripheral surface of the second rotary cylinder 6, and is pushed down by the static pressure of the static pressure pocket 82 acting on the upper end surface of the second rotary cylinder 6. The lower surface of the rotary table plate 7 is pressed against the upper end surface of the support member 3. As a result, 1 rotary table 9 is
