Abstract: A tool changer 30 with a master half 32 and tool half 34. A securing mechanism has a clasp 70 and a cam 72. The clasps 70 move between a release position and a grasping position. In the grasping position, the master 32 and tool halves 34 are secured together with one another. The cam 72 moves the clasps 70 between the release and grasping positions. From a release position, the master half 32 engages the tool half 34. The master half 32 moves laterally with respect to the tool half 34. This, in turn, moves the cam 72, and thus the clasps, from their release positions to their grasping positions. In the grasping position, the clasps 70 grasp the tool half 34, the cam locks 72 in its grasping position and the master 32 and tool 34 halves secure with one another.

Abstract: A gripping device has a body with a stepper motor positioned within the body. A lead screw is driven by the stepper motor. A gripper is coupled with the lead screw for gripping and releasing a part. A compliance enables movement of the motor with respect to the body. A controller is electrically coupled with the motor to provide motion control and maintain a set of learned positions based on sensing when the motor is approaching its stall torque.
