Abstract

PURPOSE: To measure three-dimensional forms such as the flow path of impeller at high precision and in a simple constitution, by moving a measuring arm and a recording arm in an identical three-dimensional motion using a parallelogram frame which is free to deform and turns.
CONSTITUTION: A bearing 3 to hold a measuring arm shaft 1 is supported on a support shaft 4 of an arm 8, and one end of the shaft 1 is linked to a lindage shaft 10 by way of a universal joint 6, while the other end is coupled with a probe 1a on the shaft 1. A recording arm 2 is supported and connected similarly. Thus is formed a parallelogram with a recorder 2a joined to the end of shaft 2 - probe 1a - shaft 4 - support shaft 5, and the recorder 2a - probe 1a - joints 6,7 - shafts 4,5 - joints 6,7 which is free to deform, moving about shafts 4,5. A rotatable fixed parallelogram frame 14, movable arms 11, 12, and shaft 8 are secured to posts 15, 16, so that the probe 1a and recorder 2a are engaged in identical three-dimensional motion through the parallelogram which is free to rotate, slide, and refract, thereby making it possible to measure three-dimensional forms in a simple constitution.
