GRIPPING DEVICE FOR MANIPULATOR

摘要

PROBLEM TO BE SOLVED: To realize certain gripping and grip-releasing motion with high precision and high in reliability. SOLUTION: This device is devised to control opening and closing motion of first and second fingers 24, 25 through a link member 26 interlocked with rectilinear movement of this driving body 20 by converting torque to straight motion through a ball screw mechanism 15 and a nut member 19, moving the moving body 20 in a straight line and interlocking with straght movement of this driving body 20. Thereafter, the first and second fingers 24, 25 are secured in a desired capturing region X by a positioning part 23 in its opening state.
