Abstract
A test probe positioning machine includes first and second stepper motors connected to spaced first and second vertical pivot pins extending from a support. A flat slide surface is disposed on the support adjacent and perpendicular to the vertical pivot pins. First and second elongated threaded shafts driven by the stepper motors engage first and second threaded nut blocks. The nut blocks are pivotally connected together by a vertical pivot pin and are supported upon a low friction foot element which slides along the slide surface. An insulating probe support is connected to one of the nut blocks and can be raised or lowered by a solenoid in response to a control signal received from a control system. The control system converts triangular coordinates to pulse signals which control the stepper motors to position the probe support.
