角度調整テーブル装置

Document Type and Number:

Japanese Patent JP4560235

Kind Code:

B2

Abstract:

A table system with angular position control means is disclosed in which an object supported on a table can be moved accurately over a tiny angle in circular direction to any desired position. The table(2) is supported on a bed(1) for rotation through a crossed-roller bearing(15). Position control means(3) gets the table(2) to turn over a tiny angle through an arm plate (4) fastened to the table(2). A nut and screw set(10), when driven by a motor(8), causes a linear motion that is in line with a tangent of the table(2), and the linear motion is translated into a circular motion to turn the table(2) in any circular direction by virtue of a combination of a first linear motion guide unit(6) interposed between the bed(1) and a carriage(5) to control the linear motion in the tangential direction, a second bearing means(30) interposed between the carriage(5) and a turret means(25), and a second linear motion guide unit(7) to control a linear motion in the direction that looks towards the center of the table(2).
