| 摘要 |
The present invention is a high-precision positioning post having alternating parallel cuts transversing the center-line of the shaft body and which are perpendicular to the major axis of the shaft. The shaft further comprises a bearing rod internal to the shaft which is acted on by a screw. As the screw is turned, the bearing rod forces the end of the shaft to axially translate an object without rotation. This allows an object integral to the shaft or mounted on the shaft to be translated and located along the major axis of the shaft without rotation of the object. In an alternate embodiment the present invention may be used to isolate vibration by inclusion of dampers in the hollow shaft. A third embodiment uses the basic design as a vibration isolation mechanism for buildings.
