Gripper mounting bracket

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, said first end member being generally U-shaped and having 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, 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.

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, said center member being attachable between said first and second end members at opposite lateral sides thereof, 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 adjust the clamping force via expansion and compression of said at least one gap.

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, 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.

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, said second opening being adapted to adjustably mount said mounting assembly to the support structure, opposed portions of said second end member and said center member defining at least one gap therebetween, said second end member, said center member and said first end member being secured together by at least one fastener which bridges said at least one gap between said opposed portions of said second end member and said second end of said center member, said at least one gap being expandable and contractable in response to adjusting said at least one fastener to adjust a clamping force at said second opening, said second opening defining an arcuate cross-section and being adapted to receive a swivel ring, said swivel ring being pivotable within said second opening and adapted to receive the support member therethrough, 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.
