Shape inspection unit

Abstract

Abstract PURPOSE: To enable to measure the surface shae of measured object having complicated shape with large size, accurately and automatically, by moving the detector along the ideal surface without error and detecting the deviation between the measured surface actual and the ideal surface. CONSTITUTION: After the measured object is correctly set under the shape inspection unit, the pulse motors 5, 5, 17, 17 and the pulse motor built in the carriage 10 are coupled with the desired numetrical control unit and they are operated with the NC program preset. If no error is present to the fitted position of inspected object and shape, the NC program performs that the output of the differential transformer 26 is perfectly in agreement with the reference value and the tip of the contact 22 of the contact detector 11 scans the entire inspected object surface 33 while following the desired path, and the output of the differential transformer 26 is fully recorded correctly and automatically every end of each step of the movement of the contact 22 in numerical control.
