JPS5514148A - Translational motion table - Google Patents

Abstract

PURPOSE: To achieve intended translational circular motion only by applying radius and angle information, by rotating a pinion engaged with the rack of a supporting table of a driving shaft joined at one point to a table moving in the orthogonal axial direction, and a linear guide of the supporting table by means of two concentric shafts.

CONSTITUTION: A guide 4 is rotated through gears 10, 11 and shaft 12 which are connected through rotations of a motor 9. On the other hand, the rotation of a motor 13 is transmitted to a pinion 17 through a shaft 16 which penetrates through interconnected gears 14, 15 and shaft 12 inner hole, and a slider 3 engaged with the rack is guided by the guide 4 to make linear motions. And a driving shaft 2 fixed thereto and a table 1 fixed to this shaft 2 are moved by the guides 5, 7 in the directions x, y shown by arrows or in the composite direction thereof. By applying a signal to achieve joining when the center of shaft 16 is spaced by r from the center of shaft 2 and to cause the motors 9, 13 to rotate the pinion 17 and guide 4 at the same speed and in the same direction, the table 1 is allowed to make circular translational motions at the radius of r. This apparatus may be applied for graphical drawing and working services.
