- 2. The mounting assembly of claim 1, wherein said at least one fastener is adjustable to adjust a clamping force at at least one of said first and second openings.
- 3. The mounting assembly of claim 2, wherein at least one of the workpiece holder and said pivot member are pivotable with respect to said first, second and third mounting members in response to a reduction in the clamping force.
- 4. The mounting assembly of claim 2, wherein said at least one fastener comprises a pair of fasteners extending along opposite sides of said mounting assembly, one of said fasteners being adjustable to adjust the clamping force while the other of said fasteners retains said first, second and third mounting members together.
- 5. The mounting assembly of claim 1, wherein said pivot member comprises a truncated spherical member having a cylindrical opening therethrough which is adapted to receive the support structure.
- 6. The mounting assembly of claim 5, wherein said pivot member comprises a split member with a gap extending therealong, said at least one fastener being adjustable to adjust a clamping force on the support structure via expansion or compression of said gap.
- 7. The mounting assembly of claim 5, wherein said pivot member includes a plurality of grooves extending therealong, said grooves enhancing gripping of said pivot member within said second opening.
- 8. The mounting assembly of claim 5, wherein said first and third mounting members include a beveled portion around said second opening.
- 9. A workpiece holder mounting assembly for mounting a workpiece holder to a support structure, said mounting assembly comprising:
a center member having a first end and a second end opposite said first end; a first end member attachable at said first end of said center member, said first end member and said center member defining a first opening, said first opening being generally circular and adapted to receive a cylindrical portion of the workpiece holder therethrough; and a second end member attachable at said second end of said center member, said second end member and said center member defining a second opening, whereby said second opening is adapted to pivotally receive a swivel member, said second end member, said center member and said first end member being secured together by a pair of fasteners extending longitudinally at least partially through said second end member, said center member and said first end member, said pair of fasteners being positioned laterally inwardly of an outermost lateral portion of said first opening.
- 10. The mounting assembly of claim 9, wherein said first end member is generally U-shaped and has a pair of mounting arms which receive an extension of said center member therebetween, said fasteners extending at least partially through a laterally extending portion of said center member and said pair of mounting arms of said first end member.
- 11. The mounting assembly of claim 10, wherein said first end member includes a partial ring portion which defines more than half of said first opening and extends laterally outwardly from said mounting arms and said laterally extending portion of said center member.
- 12. The mounting assembly of claim 11, wherein at least one of said pair of fasteners is adjustable to adjust a clamping force at at least one of said first and second openings.
- 13. The mounting assembly of claim 12, wherein said mounting arms of said first end member and said laterally extending portions of said center member define a first gap therebetween along at least one side of said mounting assembly, and said second end member and said laterally extending portions of said center member define a second gap therebetween along said at least one side, at least one of said fasteners extending at least partially through said second end member, said second gap, said laterally extending portion of said center member, said first gap, and said mounting arm of said first end member, whereby the clamping force is adjusted via expansion and compression of said first and second gaps.
- 14. The mounting assembly of claim 9, wherein said swivel member comprises a truncated spherical member which is pivotable within said second opening, said swivel member defining a cylindrical passageway therethrough which is adapted to receive the support structure.
- 15. A workpiece holder mounting assembly for mounting a workpiece holder to a support structure, said mounting assembly comprising:
a center member having a first end and a second end opposite said first end; a first end member attachable at said first end of said center member, said first end member and said center member defining a first opening which is generally circular, said first opening being adapted to receive the workpiece holder; and a second end member attachable at said second end of said center member, said second end member and said center member defining a second opening which defines an arcuate cross-section, whereby said second opening is adapted to receive a swivel ring, said swivel ring being pivotable within said second opening and adapted to receive the support member therethrough, said second end member, said center member and said first end member being secured together by a pair of fasteners such that loosening at least one of said pair of fasteners reduces a clamping force at at least one of said first opening and said swivel ring within said second opening.
- 16. The mounting assembly of claim 15, wherein said center member is attachable between said first and second end members at opposite lateral sides thereof.
- 17. The mounting assembly of claim 16, wherein at least one gap is defined between at least one of said sides of said center member and at least one of said first and second end members, at least one of said fasteners being adjustable to reduce the clamping force via expansion and compression of said at least one gap.
- 18. The mounting assembly of claim 15, wherein said swivel ring comprises a truncated spherical member which includes a curved outer surface and a cylindrical passageway therethrough which is adapted to receive the support structure therethrough, said curved outer surface being engagable with said second opening, said swivel ring being pivotable within said second opening when the clamping force is reduced.
- 19. The mounting assembly of claim 18, wherein said swivel ring includes a plurality of grooves extending therealong which limit pivotal movement of said swivel ring relative to said second opening when said fasteners are tightened.
- 20. The mounting assembly of claim 18, wherein said swivel ring includes a gap therealong such that a clamping force of said swivel ring on the support structure is adjustable via compression and expansion of said gap via adjustment of at least one of said fasteners.
- 21. The mounting assembly of claim 15, wherein said pair of fasteners are positioned laterally inwardly of an outermost lateral portion of said first end member.
