Abstract

A mounting and alignment system for selectively securing and accurately aligning a first plate relative to a second plate, the mounting system including a shank and a receiver arrangement with an annular locking ring and an annular receiver bushing. The bushing having an inner passage and an oppositely facing outer bushing surface. The outer bushing surface having at least one receiver bearing surface shaped to engage a bearing surface of an associated mounting opening in one of the plates to align the receiver bushing laterally within the opening. The inner passage of the bushing being shaped to receive and align with a shaft portion of the shank. The locking ring configured to secure the bushing axially within the mounting opening.

Claims

1. A mounting and alignment system for selectively securing and accurately aligning a first plate relative to a second plate, the first plate having a first plate through hole extending from a first plate outer surface to a first plate inner surface, the second plate having a second plate outer surface and a second plate inner surface, the first plate inner surface engaging the second plate inner surface when in a secured and aligned condition, the second plate further including a mounting opening extending into the second plate inner surface toward the second plate outer surface, the mounting opening having an opening peripheral surface and an opening bearing surface, said system being configured to align the mounting opening relative to the through hole thereby aligning the first plate relative to the second plate in a desired alignment, the system comprising a shank having a shaft portion extending from a head portion to a distal end spaced from the head portion, the shaft portion extending along a shaft axis between the head portion and the distal end and having a radial shaft surface coaxial with the shaft axis, the shaft surface being sized to pass through an associated first plate through hole and to laterally align the associated through hole relative to the shaft axis, the shank further including a locking arrangement selectively positionable between a locked condition and an unlocked condition;

the system further comprising an annular receiver bushing including an inner passage extending about a passage axis and a radially outwardly facing peripheral bushing surface, the inner passage being shaped to receive the shaft portion such that the shaft axis is axially aligned with the passage axis of the annular receiver bushing and the passage having a mating locking arrangement allowing the locking arrangement of the shank to selectively interengage with the receiver bushing and secure the shank relative to the receiver bushing in an axial alignment, the outwardly facing bushing surface including a receiver bearing surface sized to fittingly engage an opening bearing surface in an associated second plate thereby creating a close tolerance fit and maintaining a lateral alignment between the receiver bushing and the associated second plate opening and fixing the receiver bushing relative to the associated second plate laterally, the receiver bushing further including an upwardly facing annular support surface and a downwardly facing annular support surface;

the system further comprising a locking ring having an outer peripheral edge configured to selectively engage a locking feature of the associated mounting opening in a locked position and having a downwardly facing annular surface portion, the downwardly facing annular surface portion of the locking ring facing the upward facing annular support surface of the annular receiver bushing and restricting axial movement of the receiver bushing and maintaining the receiver bushing between the locking ring and a bottom surface formed relative to the associated mounting opening and the system securing and aligning the associated first plate relative to the associated second plate based on the axial alignment.

2. The mounting system of claim 1, wherein the locking ring is a retainer ring and the locking feature includes a locking groove extending about the associated mounting opening.

3. The mounting system of claim 1, wherein the locking ring is a retainer ring and the locking feature includes a downwardly facing locking ledge extending about the associated mounting opening.

4. The mounting system of claim 1, wherein the bottom surface is formed in the associated mounting opening as an upwardly facing locking ledge extending about the associated mounting opening and the locking ring is a retainer ring.

5. The mounting system of claim 1, wherein the locking ring is a first locking ring and the system further including a second locking ring, the locking feature is a first locking feature and the system further includes a second locking feature, the second locking ring configured to engage the second locking feature and the second ring forming the bottom surface.

6. The mounting system of claim 5, wherein the first and second locking ring are first and second retainer rings and the first and second locking features includes separate and spaced locking grooves extending about the associated mounting opening.

7. The mounting system of claim 6, wherein the first and second locking rings are the same retainer rings.

8. The mounting system of claim 5, wherein the annular receiver bushing has an axial bushing thickness and the spacing between the first and second locking rings is greater than the bushing thickness.

9. The mounting system of claim 1, wherein the surface is a bottom ledge machined into the associated mounting opening.

10. The mounting system of claim 1, further including an anti rotation pin configured to engage pin pockets in the outwardly facing bushing surface and the associated mounting opening to prevent rotation of the annular receiver bushing relative to the associated mounting opening.

11. The mounting system of claim 1, wherein the associated opening peripheral surface and the opening bearing surface are the same surface.

12. The mounting system of claim 1, wherein the outwardly facing bushing surface and the receiver bearing surface are the same surface.

13. The mounting system of claim 1, wherein the annular receiver bushing has an axial bushing thickness and the spacing between the bottom surface and the locking ring is greater than the bushing thickness.

14. The mounting system of claim 1, wherein the peripheral bushing surface includes a first peripheral bushing surface and a second peripheral bushing surface, the first peripheral bushing surface having a first diameter and the second peripheral bushing surface having a second diameter, the first diameter being greater than the second diameter forming a receiver ledge between the first and second peripheral surfaces, the locking ring being engageable against the receiver ledge and preventing outward movement of the receiver bushing from the associated mounting opening.

15. The mounting system of claim 1, wherein the locking arrangement includes at least one ball that can be forced radially outwardly to engage the mating locking arrangement in the inner passage.

16. The mounting system of claim 15, wherein the at least one ball includes a pair of opposing balls that can be forced radially outwardly in opposite directions to engage the mating locking arrangement.
