Delivery system for a remote sensor.

摘要

A mechanical delivery and remote positioning system for remotely positioning an ultrasonic sensor in mating engagement with a workpiece component to be inspected has an elongated support which can be manipulated at a first end from a remote location. A second end has an arm for carrying the sensor. An actuator rod moves the arm between a first position parallel to and within a housing and a second position wherein that portion of the arm carrying the sensor extends laterally of the housing through the housing's opening. The sensor is permitted certain limited rotation about an axis perpendicular to the arm and limited rocking about a point on that axis thereby enabling the sensor to engage the workpiece component as a result of manipulation of the first end of the elongated support despite mispositioning of the second end of the support relative to the component.
