Abstract:
A test fixture for rapidly checking the measurements of identical parts at various selected points on a non-linear contour of the parts comprising:mounting means for releasably mounting parts securely in a predetermined position; a rail that extends past the selected points of the part, the rail being positioned adjacent the outer periphery of the part and having a non-linear contour that conforms generally with the non-linear contour of the part; sensor mounting means mounted on the rail for movement past said selected points of the part, the sensor mounting means comprising a car that rides on and is supported substantially exclusively by the rail, the car being supported on the rail such that the engagement between the car and the rail maintains the car continuously in alignment with the rail along the non-linear contour of the rail; and sensor means mounted on the sensor mounting means for detecting the position of the selected points on the part relative to the position of the sensor mounting means as the sensor mounting means moves along the rail.
