Abstract
An embodiment of a multiple axis positioner comprises a main headstock that has a main hollow bore. A main indexing table is attached to the main headstock. The main indexing table has a through-hole near the its center. The through-hole aligns or is substantially coaxial with the main hollow bore of the main headstock. The embodiment of the multiple axis positioner further includes at least three minor headstocks mounted to the main indexing table. The at least three minor headstocks have minor hollow bores.
Claims20
A multistation workpiece holder apparatus comprising:
- at least one primary base;
- a primary rotary table operatively connected to the at least one primary base, where the primary rotary table includes a primary center surface defining a primary through-hole located substantially at the center of the primary rotary table;
- a plurality of secondary bases, where each of the secondary bases is operatively connected to the primary rotary table;
- and
- a plurality of secondary rotary tables, including at least a first secondary rotary table and a second secondary rotary table
- where the first secondary rotary table includes a first secondary center surface defining a first secondary through-hole located substantially at the center of the first secondary rotary table, where the first secondary rotary table is operatively connected to a first secondary base,
- where the second secondary rotary table includes a second secondary center surface defining a second secondary through-hole located substantially at the center of the second secondary rotary table, and where the second secondary rotary table is operatively connected to a second secondary base.
A robotic welding positioner comprising:
- a main headstock having a main hollow bore and a main indexing table, where the main indexing table includes a center surface forming a main through-hole on the main indexing table, where the main through-hole is substantially coaxial with the main hollow bore;
- and
- at least three minor headstocks operatively connected to the main indexing table, where the at least three minor headstocks have minor hollow bores.
A workpiece positioner comprising:
- a rotary platform having a top surface and a center surface forming a main through-hole;
- means for holding a plurality of workpieces, where the means for holding include minor center surfaces forming minor through-holes, and where the means for holding are operatively connected to the top surface;
- and
- means for rotating the rotary platform about an axis of rotation perpendicular to the top surface, where the means for rotating the rotary platform are located such that the main through-hole is unobstructed.
