Publication number: 20210138635Abstract: A gripper includes at least one tooling member including: a base; a distal segment coupled to the base and configured to grip a workpiece; a series of identical intermediate segments coupling the base to the distal segment, each of the intermediate segments being coupled to at least one other intermediate segment; and a fastener coupling two adjacent intermediate segments together. The fastener defines a first position where the coupled adjacent intermediate segments are articulationally and translationally locked to one another and a second position where the coupled adjacent intermediate segments are translationally locked to and articulationally unlocked from one another.Type: ApplicationFiled: October 8, 2020Publication date: May 13, 2021Applicant: PHD, Inc.Inventors: Daniel L.

Patent number: 9140301Abstract: The present invention provides a machine guideway including a base, a shaft placed in a groove within the base, a carriage slidably connected to the base and shaft, a pair of opposed wheels held by the carriage, and a cover placed over the pair of opposed wheels. The groove has an arch shape defining a groove arch radius. The shaft defines a shaft radius less than the groove arch radius. Each opposed wheel of the pair of opposed wheels contacts the shaft at a rolling point and has a plurality of radii. The plurality of radii of each opposed wheel together form a pair arch when the opposed wheels are held by the carriage. The pair arch defines a pair arch radius that is greater than the shaft radius. The cover is configured to keep the pair of opposed wheels in contact with the shaft with a pre-loaded force.Type: GrantFiled: April 16, 2014Date of Patent: September 22, 2015Assignee: PHD, INCInventors: Matthew R. Williams, Lyle A. Null

Patent number: 8905452Abstract: A gripper for gripping a workpiece includes a jaw assembly having an actuator with a housing and an elongate member axially slidably movable within the housing. A force-multiplying mechanism is interconnected between the elongate member and the housing. The force-multiplying mechanism is configured to add a mechanical force to the jaw assembly and thereby increase a gripping force on the workpiece during operation of the gripper.Type: GrantFiled: October 12, 2012Date of Patent: December 9, 2014Assignee: PHD, Inc.Inventors: Matthew R. Williams, Lyle A. Null

Patent number: 8894118Abstract: A gripping device including a main body, a first elongate actuator, a second elongate actuator, a first jaw, a second jaw, a first pin, a second pin, a pair of pulleys, and a cable. The elongate actuators are both disposed in respective actuator bores within the main body and translate opposingly to each other. The jaws are both driven by a respective elongate actuator. The pins both include respective pin bodies defining a channel and are configured to drive their respective jaw by a respective elongate actuator and are disposed through transverse holes formed in the respective elongate actuator and a respective pin slot formed in the main body. The pulleys are attached to the main body. The cable forms a closed loop around the pulleys through the channels and is affixed to the first channel to inhibit relative movement between the first channel and the cable.Type: GrantFiled: October 9, 2013Date of Patent: November 25, 2014Assignee: PHD, Inc.Inventors: Lyle A. Null, Matthew R. Williams

Publication number: 20140117689Abstract: A device for gripping an object including a gripper head, an actuator, and a cable assembly. The gripper head includes at least one movable jaw. The actuator is located remotely from the gripper head. The cable assembly connects the gripper head to the actuator and is configured to drive the gripper head by the actuator.Type: ApplicationFiled: October 25, 2013Publication date: May 1, 2014Applicant: PHD, Inc.Inventors: James M. Davis, Lyle A. Null, Matthew R. Williams, Scott A. Shepherd

Patent number: 8152214Abstract: A gripper assembly which in one form includes a body, at least one jaw, a longitudinally extending wedge, and a spring. The body has a slot disposed therein and opposed longitudinally extending walls. The jaw is laterally slideable within the slot. The longitudinally extending wedge is fitted along the longitudinally extending wall. The jaw comprises a surface that is engageable with the wedge. The surface of the jaw is slideable along the wedge. And a spring biases the wedge toward the jaw to reduce the running clearance between the two structures.Type: GrantFiled: September 3, 2009Date of Patent: April 10, 2012Assignee: PHD, Inc.Inventors: Matthew R. Williams, Lyle A. Null, Matthew Wenger

Patent number: 6598918Abstract: A synchronizing mechanism for parallel gripper and clamp assemblies which includes one or more synchronizing elements that are coupled to elongate jaw guides which guide the parallel reciprocal motion of opposed jaw members. According to one embodiment, a single synchronizing element is used which includes slots on opposite sides. The single synchronizing element is coupled to the elongate jaw guides by pins or other coupling structure or elements which are positioned in the slots and are coupled to the elongate jaw guides. According to another embodiment two synchronizing elements which pivot or rotate about a common axis and which slide relative to one another are used. In other embodiments the synchronizing mechanism can include a rotating element and shuttle elements which are configured to slide along or within the rotating element in slots or through-holes provided therein.Type: GrantFiled: September 3, 1999Date of Patent: July 29, 2003Assignee: PHD, Inc.Inventors: Lyle A. Null, Gordon Kistler
