Abstract
The present invention relates to an elastic corrugated pipe single-acting cylinder-driven mechanical gripper with a series-connection loose-leaf hinge framework. The mechanical gripper consists of a palm and two flexible fingers or a palm and three flexible fingers. The flexible fingers are identical in structure, and each one of the flexible fingers consists of an elastic corrugated pipe single-acting cylinder and a series-connection loose-leaf hinge. Each one of the series-connection loose-leaf hinges has a hinge mandrel equipped with a torsion spring, and the characteristic parameters and pre-tightening angle of the torsion spring are optimally designed according to the features of a grasped object. The mechanical gripper is driven by the elastic corrugated pipe single-acting cylinder to generate a grasping force. The mechanical gripper applies to the grasping of fragile brittle objects, or grasping of objects with varying shapes and dimensions.
