Abstract
A palm-type mechanical gripper with variable-position and rotatable fingers and a crank-rocker-slider parallel mechanism adopts crank-rocker-slider mechanisms and three identical flexible plate spring fingers, wherein one finger is fixed, and the other two fingers can rotate and move to achieve translational motions and are respectively and symmetrically installed on connecting rods or rockers on left and right sides. The crank-rocker-slider mechanism on the left side is an active driving structure and is driven by two stepping motors to respectively generate angular displacement of cranks and linear movement of sliders. The crank-rocker-slider mechanism on the right side is a driven mechanism and is driven at a constant speed by a pair of gears. The eccentricities of the cranks, the positions and angles of the two fingers respectively on the two connecting rods or rockers and the position of the other fixed finger can be changed through manual adjustment.
