35, 1983, discusses the Stuart platform. In this paper, for example, as shown in FIG. 7, a base 1 and a movable table 2 are connected by six links 31 to 36.

ことが困難である。However, in the configuration of the ball pairs 51a to 56a and 51b to 56b used in the above-mentioned multi-degree-of-freedom spatial movement mechanism, the gap between the outer circumferential surface of the sphere and the sliding surface that slides on this outer circumferential surface, and the gap between the two. Due to machining errors, even if the actuators 41 to 46 are formed with high precision, the ball pair 51a, 51b at the end of the links 31 to 36 connected to the actuators 41 to 46 may be formed with high precision.
Even if the axial positions of the spherical parts of 56a and 56b are held constant, the center position of the spherical part and the sliding surface that slides on the outer peripheral surface thereof, that is, the swing center position of the base 1 or the movable table 2. A discrepancy occurs between the two. Therefore, it is difficult to control the position and orientation of the movable table 2 with accuracy on the order of submicrons.

これら2個の切欠穴10a。In the same figure, 6 is a base, 7 is a moving table, 81-a to 86a and 81b to 86b are pairs of links, 12 in total, and the outer tip of each link is connected to the base 6.
It is firmly fitted into the moving table 7 as one body, and two notched holes 10a and 10b having the same shape are bored at both ends of the moving table 7, symmetrically with respect to the center line 0-0' in the width direction, near the outer tip of the moving table 7. These two cutout holes 10a are provided.

を検出する変位検出器が取付けられている。The connecting portion 9 has a width W between the portions 10b that is narrow, thereby making the rigidity of this portion smaller than that of the base 6 and the movable table 7. Actuator bodies 11a to 16 each have a cylindrical shape and have one end open, and the rear end of one of the links 81a to 86a or 81b to 86b is screwed to the other end. 16a, and this actuator body 11a to 16a
Voltage elements 11b to 16b that are loosely fitted into the inner circumference and fix electrodes 11c to 16c inserted on the inner circumferential surface of the actuator bodies 11a to 16a on the outer circumferential surface, and the piezoelectric terminal 11
one end is connected to the outer end of the electrodes 11C to 16b, and attachment parts lid to 16d are screwed to the other ends to screw the rear ends of the other links 81b to 86b or 81a to 86a. When voltage is applied to 16c to 16c,
Piezoelectric elements 11b to 16b, actuator body 11a
The lengths of the links 81a to 86a and 81b to 86b are slightly moved via the attachment parts lid to 16d. Although not shown, a displacement detector is attached to each link 81a to 86b and 81b to 86b to detect the length thereof.

9はその巾方向中心線○−○′上の中心点を中心点01
にして回ねり対偶を形成する。Since the degree-of-freedom spatial fine movement mechanism according to the present invention is constructed as described above, when force is applied from the moving table 2 to the links 81a to 86a and 81b to 86b, the connecting portion 9 is deformed, as shown in the chain double-dashed line in FIG. Since the connection part 9 swings as shown in , the center point on the center line ○-○' in the width direction is the center point 01
to form a turning pair.

その中心線0−o′を中心点01にして回動させる力が
加わると、リンク81a乃至86aおよび81b乃至8
6bは回動するので、接続部9は球対偶を形成する。Further, when a force is applied to the links 81a to 86a and 81b to 86b to rotate them with their center lines 0-o' as the center point 01, the links 81a to 86a and 81b to 86b
Since 6b rotates, the connecting portion 9 forms a pair of balls.

示す球対偶と同一機能を行なう。Further, the actuators 11 to 16 actuate the link 81a.
When the lengths of 86a to 86a and 81b to 86b are slightly moved, the position and posture of the movable table 7 is bent and torsionally deformed about the center point OI on the width direction center line 0-○' of the connecting portion 9. Therefore, the connecting portion 9 performs the same function as the ball pair shown in FIG. 7.
すなわち、上記接続部9は、弾塑性変形によす球対偶の
機能を等価的に実現させることができる。In other words, the connecting portion 9 can equivalently realize the function of a pair of spheres through elastic-plastic deformation.
また弾塑性変形のさい接続部9の中心位置0旨ま常に一

にて接続したり。In the above embodiment, a case was described in which the connecting portion of each link was formed with two notched holes in the width direction.
However, the present invention is not limited to this. For example, as shown in FIG. 4, the connecting portion 9' may be made circular with a small diameter 17, or as shown in FIG. These links 18 are divided into small diameter round rods 18b.

It is also possible to insert a member 19a made of a material with lower rigidity than the moving table 7.
以上述べたる如く1本発明によれば、ベース。 As described above, one aspect of the present invention is a base.

The position and attitude of the moving platform can be controlled with precision.
