Abstract:
An adaptor for securing an elongated workpiece, such as an elongated pin, in a workpiece fixture is disclosed, wherein the adaptor is adjustable for repositioning the workpiece to facilitate a machining operation thereon. The adaptor includes a holding assembly for holding a workpiece in the adaptor and a securing assembly for securing the holding assembly in a workpiece fixture so that the workpiece and the holding assembly are repositionable with respect to the fixture. In a first embodiment of the adaptor, the securing assembly is operable for repositioning the holding assembly in a horizontal direction which is substantially perpendicular to the longitudinal extent of the workpiece, whereas in a second embodiment of the adaptor the securing assembly is operable for repositioning the holding assembly in both horizontal and vertical directions.
