PURPOSE: To accurately track the position of a turret by screwing the end of an encoder drive shaft into an expandable hub shaft fixture so as to directly fix the encoder to the turret shaft of an assembly. CONSTITUTION: An encoder 24 is fixed to a machine frame bracket 26 via screws 25 and coupled with a drive shaft 28, piercing downwardly a hole 30 of the bracket 26 and a coaxial hole 32 of a manifold. The drive shaft 28 has a threaded end screwed into and tightened to a threaded hole of a bottom member 44, until the shoulder of the shaft 28 butts to the bottom of a recess 41 of a top member 42, resulting in that a turret assembly clamps a fixture 40 to a turret shaft 21 and to annular fitting tubular portions 42a, 44a of the top and bottom members 42, 44. |
