Claims
- 1. An arrangement for pressing a press-fit part into a receiving portion of a receiving assembly, the arrangement comprising:a first measuring arrangement for measuring a predetermined dimension of the press-fit part; a first probe for communicating with an inner surface of the receiving portion of the receiving assembly; a second probe for communicating with an outer surface of the receiving portion of the receiving assembly; a differential measurement arrangement for producing a first electrical measurement signal responsive to a difference in the displacements of said first and second probes; a press drive for urging the press-fit part onto the receiving portion of the receiving assembly; and an impulse drive for applying an impetus of short duration to the press-fit part.
- 2. The arrangement of claim 1, wherein the receiving portion of the receiving assembly onto which the press-fit part is to be pressed is a pocket of the receiving assembly, and there is further provided a holding arrangement for holding the press-fit part in position to be urged into the pocket of the receiving assembly by said press drive.
- 3. The arrangement of claim 1, wherein there is further provided a force measuring arrangement for measuring an insertion force applied to the press-fit part by said press drive.
- 4. The arrangement of claim 1, wherein there is further provided a bearing interposed between said first and second probes.
- 5. The arrangement of claim 4, wherein said bearing comprises an interference fit ball bearing arrangement interposed between said first and second probes.
- 6. The arrangement of claim 1, wherein said first probe is arranged to communicate with the inner surface of the pocket of the receiving assembly at a plurality of locations thereon.
- 7. The arrangement of claim 1, wherein said second probe is arranged to communicate with the outer surface of the pocket of the receiving assembly at a plurality of locations thereon.
- 8. The arrangement of claim 1, wherein there is further provided an angular displacement arrangement coupled to said first probe, wherein said first probe is arranged to be angularly displaceable with respect to an axis of translation thereof directed toward said pocket of the receiving assembly and substantially self-aligning with respect thereto.
- 9. The arrangement of claim 1, wherein said first and second probes are arranged to be axially parallel with respect to each other.
- 10. The arrangement of claim 1, wherein said press drive is provided with an angular displacement drive arrangement for communicating with said press-fit part and rendering said press fit part to be angularly displaceable with respect to an axis of translation of said press fit part directed toward said pocket of the receiving assembly and substantially self-aligning with respect to said pocket of the receiving assembly.
- 11. The arrangement of claim 10, wherein the angular displacement of said press drive is responsive to a radius that originates at a distal seating plane of the press-fit part.
- 12. An arrangement for pressing a press-fit part into a receiving portion of a receiving assembly, the arrangement comprising:a first measuring arrangement for measuring a predetermined dimension of the press-fit part; a second measuring arrangement for measuring the receiving portion of the receiving assembly; a press drive for urging the press-fit part onto the receiving portion of the receiving assembly; an impulse drive for applying an impetus of short duration to the press-fit part; and an angular displacement drive arrangement for communicating with said press-fit part and rendering said press fit part to be angularly displaceable with respect to an axis of translation of said press fit part directed toward the receiving portion of the receiving assembly and substantially self-aligning with respect to the receiving portion of the receiving assembly.
- 13. The arrangement of claim 12, wherein the angular displacement of said press drive is responsive to a radius that originates at a distal seating plane of the press-fit part.
- 14. The arrangement of claim 12, wherein said second measuring arrangement comprises:a first probe for communicating with an inner surface of the pocket of the receiving assembly; a second probe for communicating with an outer surface of the pocket of the receiving assembly; and a differential measurement arrangement for producing a first electrical measurement signal responsive to a difference in the displacements of said first and second probes.
- 15. The arrangement of claim 12, wherein the receiving portion of the receiving assembly onto which the press-fit part is to be pressed is a pocket of the receiving assembly, and there is further provided a holding arrangement for holding the press-fit part in position to be urged into the pocket of the receiving assembly by said press drive.
