Abstract
The disclosure relates to a mechanical hand of a dual-driven special-shaped super-flexible elastic framework. The mechanical hand includes a top plate and a base plate. The top plate and the base plate are fixed into a whole through two groups of guide connection rods. Two lead screw shaft servo motors are disposed on the top plate at an interval. Lead screws of the two lead screw shaft servo motors are respectively connected to a hollow finger front section driving plate and a finger root portion driving plate. Tail ends of the two lead screws are respectively supported on the base plate through two mounted bearings. The mechanical hand further includes flexible fingers. A tip portion of each of the flexible fingers is fixed on the hollow finger front section driving plate. A special-shaped super-flexible leaf spring of the flexible finger is connected to the base plate through a finger root hinge seat. A curved rod of the flexible finger is connected to the finger root portion driving plate through a curved rod hinge seat. The two lead screw shaft servo motors convert rotation movements into linear movements through lead screw nut mechanisms, and different portions of the flexible finger are respectively driven to move. Objects of different sizes and states are reliably grasped. A grasping range is wide. A flexible self-adaption effect is achieved.
