Test head vertical support system

摘要

A manipulator for translating a load along an axis of translation is provided. The manipulator comprises an outer column and a telescoping column positioned adjacent the outer column. The telescoping column is attached to the load and configured to translate the load along the axis of translation. At least one guiding member is mounted between the outer column and the telescoping column, wherein the guiding member is configured to guide the telescoping column as the telescoping column translates along the axis of translation.

1. A load positioning system for translating a load along an axis of translation, said load positioning system comprising:
a support for supporting said load; a fluidly operated piston configured to drive said support along said axis of translation; a regulator unit configured to control a pressure of a primary fluid delivered to said fluidly operated piston, said regulator unit receiving said primary fluid and a further fluid, wherein said regulator unit receives said primary fluid independently of said further fluid and said further fluid is excluded from said fluidly operated piston; and a control unit configured to control a pressure of said further fluid to said regulator unit, wherein increasing the pressure of said further fluid causes said pressure of said primary fluid to be increased and said support to move in a first direction, decreasing the pressure of said further fluid causes said pressure of said primary fluid to be decreased and said support to move in the opposite direction, and maintaining the pressure of said further fluid at a constant pressure substantially maintains the position or speed of said support along said axis of translation.
