Abstract
20th century since the 90's, CNC machining technology is the rapid popularization and development. Machining center and flexible manufacturing systems with a tool changing was a tremendous development. It makes the processing quality and productivity to be increased dramatically. The graduation project, mainly to complete the end of the robot manipulator ATC - tool changing the structural design of claw hands.
The tool changing robot complete gripper tool changing tools and action taken, which move by the servo motor driven screw drive gripper rotary driven by the servo motor, speed reducer, solenoid-driven Zhang gripper, gripper closing spring so that, part of the completion of gripper tool changing knives and action taken. The graduation project analysis requirements and the main functions of the robot tool changing based on the research about machining center and automatic tool changing device at home and abroad .This article introduces the overall structure of claw hands, wrist kinematic parameters degrees of freedom, the choice of wrist motor, reducer selection, and the hand count and calculation of the structural design and the selection electromagnet.
