Patent number: 7673377Abstract: A rivet is inserted into a workpiece by an apparatus that includes an internal roller screw linear actuator in which rotational movement of an internally threaded cylinder is converted into linear movement of a fastener insertion actuator assembly. The cylinder is driven in rotation by a servo-controlled motor. The angular velocity of the cylinder required to deliver the required energy to effect fastener insertion is calculated and the motor is first controlled to accelerate the cylinder up to the calculated angular velocity, the actuator assembly simultaneously being moved by the cylinder towards the workpiece. The motor is then controlled to maintain the angular velocity of the cylinder at not less than the calculated magnitude at least until insertion of the fastener. The cylinder stores kinetic energy by virtue of its inertia. Using this inertia to insert fasteners eliminates the need for position or force feedback control. The process allows for a rapid cycle time and the apparatus is compact.Type: GrantFiled: September 13, 2005Date of Patent: March 9, 2010Assignee: Henrob LimitedInventor: Nicholas Richard Clew

Patent number: 7418774Abstract: An automatic rivet loading module which includes a pusher mechanism, a gripper mechanism, a mandrel receptacle, mechanisms for moving mandrels in the mandrel receptacle, and a tool activation device. The gripper mechanism receives a rivet, and a mandrel is moved through the rivet such that the rivet threads onto the mandrel. The gripper mechanism moves out of the way while the pusher mechanism pushes the mandrel down. The pusher mechanism then retracts, and the gripper mechanism closes and is ready to receive another rivet. This process is repeated until the mandrel is full of rivets. The mandrel receptacle is rotatable such that the loaded mandrel swings to a position under the tool activation device to be loaded into a rivet tool. As the loaded mandrel is swung under the tool activation block, a new mandrel is swung under the gripper mechanism, in position for loading with rivets.Type: GrantFiled: December 5, 2005Date of Patent: September 2, 2008Assignee: Acument Intellectual Properties, LLCInventors: James W. Joseph, Wim Bouman
