Title:
LINK MECHANISM REFRACTED AT ANGLE IN SEMI-SPHERICAL SURFACE
Document Type and Number:
Japanese Patent JPH01188288
Kind Code:
A
Abstract:
PURPOSE:To simplify and miniaturize a link-construction by providing a reduction motor for driving a parallel link-mechanism. CONSTITUTION:Supporting points C, C' of the head of an E type arm 2 in a parallel link-mechanism is moved along a path in a semi-circle through worm gears 6, gears 4 by a reduction motor 5, and a joint bars 7 inserted into the supporting points C,C', mating E type arm 9, and an arm case 10 are forced to be inclined at an optional angle in a semi-circle. Next, supporting points F, F' of the head of the E type arm 9 in the parallel link-mechanism are moved along a path in a semicircle through worm gears 14, gears 12 by an another induction motor 13, and the E type arm 2 and an arm case 1 on the side opposed to the supporting points E, E' are tilted at an optional angle in a semicircle. The arm case 1 and the arm case 10 are refracted at an angle in a semi- spherical surface by the composition of a vertical semicircular motion of the arm case 1 and a crosswise semicircular motion of the arm case 10.
