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.

1. A pin clamp assembly comprising: a housing;a locating pin movable with respect to the housing;wherein the locating pin can selectively entirely retract inside the pin clamp;a finger supported by the locating pin and retractable and extendable into and out of the locating pin;wherein the finger is extendable out of the locating pin when at least a portion of the locating pin supporting the finger is exterior of the housing; anda first actuator that contributes to moving the locating pin without moving the finger. 2. The pin clamp assembly of claim 1, wherein movement of the finger is independent of movement of the locating pin. 3. The pin clamp assembly of claim 1, further comprising a surface located on the housing, wherein the surface identifies a plane; the locating pin further comprising a tip at its proximal end wherein the tip of the locating pin does not extend beyond the plane when the locating pin is retracted entirely inside the housing. 4. The pin clamp assembly of claim 3, wherein when the locating pin is selectively entirely retracted inside the housing the pin clamp assembly is configured to receive a workpiece that moves laterally with respect to the pin clamp assembly. 5. The pin clamp assembly of claim 1, further comprising a second actuator that contributes to moving the finger without moving the locating pin. 6. The pin clamp assembly of claim 1, further comprising first and second actuators wherein the first actuator moves the locating pin and the second actuator moves the finger. 7. The pin clamp assembly of claim 6, wherein the first and second actuators comprise either pneumatic or electrical systems. 8. The pin clamp assembly of claim 1, wherein the finger includes a hook. 9. The pin clamp assembly of claim 1, further comprising a second finger supported by the locating pin and is retractable and extendable into and out of the locating pin. 10. The pin clamp assembly of claim 1, further comprising a lock bracket that selectively limits movement of the locating pin. 11. The pin clamp assembly of claim 10, wherein the lock bracket prevents the locating pin from extending to loosen the finger's grip on the workpiece. 12. The pin clamp assembly of claim 10, wherein the lock bracket pivots to selectively block movement of the locating pin. 13. The pin clamp assembly of claim 10, further comprising a spring that attaches to the lock bracket to assist moving the lock bracket. 14. The pin clamp assembly of claim 4, further comprising a part support that includes an opening configured to receive the locating pin and includes the surface to support the workpiece. 15. The pin clamp assembly of claim 14, further comprising a dowel located in the housing and disposed in a movable piston rod and in an opening in the locating pin, wherein the piston rod is selectively movable without moving the locating pin. 16. The pin clamp assembly of claim 15, further comprising a first actuator that moves the piston rod causing the pin to engage a cam surface on the lock bracket which engages a cavity surface in the housing preventing the lock bracket from rotating. 17. The pin clamp assembly of claim 16, wherein as piston rod continues to move, the locking bracket and locating pin also move. 18. The pin clamp assembly of claim 17, wherein as piston rod and locating pin continue to extend, the finger is retracted. 19. The pin clamp assembly of claim 18, wherein once the locating pin has extended enough that the locking bracket clears the cavity surface, the locking bracket rotates and stops when a dowel engages a clearance notch in the locking bracket. 20. The pin clamp assembly of claim 19, wherein both the locating pin and locking bracket continue to move so the locating pin extends exterior of the housing after the dowel engages the clearance notch. 21. The pin clamp assembly of claim 20, further comprising a cam that is movable laterally with respect to the locating pin, and wherein when the locating pin is extended. 22. The pin clamp assembly of claim 21, wherein at least a portion of the cam is movable exterior of the locating pin. 23. The pin clamp assembly of claim 22, further comprising an actuator that acts on the cam to move it laterally with respect to the locating pin. 24. The pin clamp assembly of claim 23, further comprising a drive rod in communication with the cam and with the finger such that as the cam moves the drive rod relative to the locating pin, the cam causes the drive rod to extend the finger from the locating pin. 25. The pin clamp assembly of claim 24, wherein as the finger remains extended, locating pin is retractable allowing lock bracket to be rotatable via a spring. 26. The pin clamp assembly of claim 25, wherein the locking bracket is engageable with a stop. 27. The pin clamp assembly of claim 26, wherein the stop is adjustable. 28. The pin clamp assembly of claim 27, wherein once the lock bracket engages the stop the locating pin is prevented from extending further out of the housing.
