Differential Translational Gripper with Double-Claw of Manipulator Driven by Combined Cylinder

To meet the requirement of feeding robot for assembly equipment, the differential translational gripper with double-claw of manipulator driven by combined cylinder is designed in this paper, which could achieve the differential operation with high efficiency. It has the function of automatic center aligning and adaptation to the changing dimension of the workpiece with high assembly precision. Since the gripper is driven by combined cylinder, it simplifies the control system and structure of manipulator with compact size and light weight, and also solves the problem of complicated structure and mass volume of traditional translational gripper driven by rack and pinion.
