| 20120111187 | FLOW CONTROL NEEDLE MICRO ADJUSTMENT ASSEMBLY - A fluid cylinder actuator assembly is provided. The assembly includes a cylinder tube and a cushion control needle assembly. The cushion control needle assembly is configured to extend into the fluid cylinder actuator assembly to control fluid that exits the cylinder tube and comprises: a threaded cushion control differential screw that selectively screws into a retainer having corresponding threads; a control needle that includes a stem selectively extendable through a bore in the retainer opposite of the cushion control differential screw; wherein the stem of the control needle is engageable with a threaded bore inside the cushion control differential screw that is complimentary to the threads formed on the stem so that rotating the threaded cushion control differential screw will selectively extend or retract the control needle back and forth; and wherein threads of the threaded cushion control differential screw is different than the threads in its threaded bore. | 05-10-2012 |
| 20100052348 | GRIPPER WITH SELF-COMPENSATING JAW GUIDES - The present disclosure describes 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. | 03-04-2010 |
| 20090315236 | STRIP OFF PIN CLAMP - A pin clamp assembly is provided that includes a housing, a locating pin, and a finger. The locating pin is movable with respect to the housing. The locating pin can also selectively entirely retract inside the housing. A finger is supported by the locating pin and retractable and extendable into and out of the locating pin. The finger is also extendable out of the locating pin when at least a portion of the locating pin supporting the finger is exterior of the housing. | 12-24-2009 |
| 20090121403 | PIN CLAMP - A pin clamp assembly is provided which includes a housing, a locating pin, a body, a twist pin, and a cam pin. The locating pin extends from the body. Both the body and the locating pin include longitudinally extending cavities contiguously disposed therein. The body also includes a longitudinally extending slot. At least a portion of the locating pin and the body is located in a bore disposed through the housing. The twist pin is disposed in the longitudinally extending cavities of the locating pin and body. The twist pin includes a longitudinally extending arcuate slot. The cam pin is coupled to the housing. The cam pin engages the slot. An electrical driven actuator includes an electric motor that rotates to move the locating pin linearly to rotate the twist pin. | 05-14-2009 |
| 20090096146 | Pin Clamp Assembly - A pin clamp assembly having a housing, locating pin, at least one finger, a drive rod and an actuator is provided. At least a portion of the locating pin may be extendable exterior of the housing. The finger is located adjacent the locating pin and movable relative thereto. The drive rod is movable and is engagable with the finger to move the finger between clamped and unclamped positions. The actuator drives the locating pin and the drive rod. Movement of the locating pin and drive rod is linear only and no rotational movement of the locating pin and drive rod is employed to move the finger between clamped and unclamped positions. | 04-16-2009 |
| 20080315478 | PIN CLAMP ASSEMBLY - A pin clamp assembly having a body, a locating pin, an actuator, a drive rod, a cam, and a finger is provided. The locating pin is coupled to the body and movable between extended and retracted positions. The drive rod is movable relative to the locating pin. The cam is movable relative to the locating pin and the drive rod. The finger is coupled to the drive rod and movable between extended and retracted positions. Actuation of the actuator causes the drive rod to move which extends the finger without moving the locating pin. Also, continued retraction of the drive rod after the finger has extended causes the cam to move out from the slot in the body to allow the locating pin to retract. | 12-25-2008 |
| 20080315477 | PIN LOCATING ASSEMBLY - A locating pin assembly is provided. The assembly includes a body and a cylinder assembly for moving a ram in a reciprocally linear manner. A bearing is coupled to the ram and configured to engage a bearing wedge to reduce “play” between the ram and the assembly. Illustratively, the bearing and bearing wedge reduce or substantially eliminate this “play” to prevent axial rotation of the ram. | 12-25-2008 |
