A linearly adjustable apparatus having a stroke adjustment for locating geometric references on a workpiece. The present invention provides a housing having a linear actuator for actuating a locating member between an extended position, wherein the locating member engages the workpiece, and a retracted position, wherein the locating member disengages the workpiece. A bearing assembly is connected to the housing and slidably supports the locating member. The bearing assembly has an external threaded portion that threadably engages an internal threaded portion of the housing to provide linear adjustment of the stroke length of the locating member along a longitudinal axis of the housing. A jam nut threadably engages the bearing assembly to secure the relative position of the bearing assembly relative to the housing.

What is claimed is: 1. A linearly adjustable apparatus for locating a workpiece, comprising: a housing having a longitudinal axis; a locating member at least partially disposed within said housing for movement along said longitudinal axis between an extended position, wherein said locating member is engageable with said workpiece, and a retracted position, wherein said locating member is not engageable with said workpiece; a bearing threadably connected to said housing for slidably supporting said locating member between said extended position and said retracted position wherein said bearing member does not move relative to said housing during movement of said locating member between said extended position and said retracted position; and said bearing threadably adjustable to said housing for linearly adjusting the stroke of said locating member between said extended position and said retracted position. 2. The linearly adjustable apparatus stated in claim 1, further comprising: a linear actuator connected to said housing and coupled to said locating member for actuating said locating member between said extended position and said retracted position. 3. The linearly adjustable apparatus stated in claim 1, further comprising: said bearing cooperatively engaging and stopping said locating member in said extended position. 4. The linearly adjustable apparatus stated in claim 3, further comprising: a connector coupled to said bearing and said housing to prevent relative movement between said bearing and said housing. 5. The linearly adjustable apparatus stated in claim 4, wherein said connector further comprises: a jam nut releasably connected to said bearing and said housing. 6. The linearly adjustable apparatus stated in claim 4, wherein said connector further comprises: a set screw extending through a threaded aperture in said housing and engaging said bearing to prevent movement of said bearing relative to said housing. 7. A linearly adjustable apparatus for locating a workpiece, comprising: a housing having a longitudinal axis and a linear actuator connected thereto; a locating member at least partially disposed within said housing for actuation by said linear actuator along said longitudinal axis between an extended position, wherein said locating member is engageable with said workpiece, and a retracted position, wherein said locating member is not engageable with said workpiece; a bearing threadably connected to said housing for slidably supporting said locating member between said extended position and said retracted position wherein said bearing member does not move relative to said housing when said locating member moves between said extended position and said retracted position, and said bearing positively stopping said locating member in said extended position; and said bearing threadably adjustable along said longitudinal axis of said housing for adjusting the stroke length of said locating member between said extended position and said retracted position. 8. The linearly adjustable apparatus stated in claim 7, further comprising: said bearing having a threaded portion threadingly engaging a threaded portion of said housing wherein the threading of said bearing in and out of said housing provides linear adjustment of the stroke length of said locating member along said longitudinal axis of said housing. 9. The linearly adjustable apparatus stated in claim 8, further comprising: a jam nut releasably engaging said threaded portion of said bearing and said housing to prevent relative movement between said bearing and said housing. 10. The linearly adjustable apparatus stated in claim 8, further comprising: a set screw extending through a threaded aperture in said housing and engaging said bearing to prevent relative movement between said bearing and said housing. 11. The linearly adjustable apparatus stated in claim 8, wherein said bearing further comprises: an inner, substantially cylindrical portion for slidably receiving said locating member; and an outer, substantially cylindrical portion connected to said inner portion and having said threaded portion of said bearing formed thereon. 12. The linearly adjustable apparatus stated in claim 7, further comprising: said locating member having a shoulder; and said bearing having a shoulder for engaging said shoulder of said locating member for positively stopping said locating member in said extended position. 13. A linearly adjustable apparatus for locating a workpiece, comprising: a housing having a longitudinal axis and a linear actuator connected thereto; a locating member at least partially disposed within said housing for actuation by said linear actuator along said longitudinal axis of said housing between an extended position, wherein said locating member is engageable with said workpiece, and a retracted position, wherein said locating member is not engageable with said workpiece; a bearing disposed within said housing for slidably supporting said locating member between said extended position and said retracted position and positively stopping said locating member in said extended position; and said bearing having an external threaded portion for threadingly engaging an internal threaded portion of said housing wherein the threading of said bearing into and out of said housing provides linear adjustment of the stroke of said locating member along said longitudinal axis of said housing. 14. The linearly adjustable apparatus stated in claim 13, further comprising: a jam nut threadingly engaging said external threaded portion of said bearing and engaging said housing to prevent relative movement between said bearing and said housing. 15. The linearly adjustable apparatus stated in claim 13, further comprising: a set screw extending through a threaded aperture of said housing and engaging said bearing to prevent the relative movement between said bearing and said housing. 16. The linearly adjustable apparatus stated in claim 13, wherein said bearing further comprises: an inner, substantially cylindrical portion for slidably receiving said locating member; and an outer, substantially cylindrical portion connected to said inner portion and having said external threaded portion of said bearing formed thereon. 17. The linearly adjustable apparatus stated in claim 16, further comprising: said locating member having a shoulder; and said outer portion of said bearing having a shoulder for engaging said shoulder of said locating member and positively stopping said locating member in said extended position. 18. The linearly adjustable apparatus stated in claim 17, further comprising: said shoulder on said locating member fabricated from a splined cylinder overlying and connected to said locating member in a substantially coaxial fashion. 19. The linearly adjustable apparatus stated in claim 13, further comprising: said internal threaded portion of said housing fabricated from an end block having a threaded aperture extending therethrough wherein said end block is connected to said housing.
