MEASURING DEVICE FOR DIMENSION OF PLURAL POINTS FROM STANDARD SURFACE

摘要

PURPOSE:To simultaneously measure plural points and to remove measurement errors due to the distortion of a standard surface by fitting plural measuring machines to a movable plate of which intermediate part is formed to be a thin part to measure the dimensions of these plural points from the standard surface. CONSTITUTION:An intermediate part of a movable plate 11 on which differential transformers 27 are mounted so as to be opposed to plural measuring points is formed in thin wall 11d. Standard legs 17 and an intermediate leg 18 which are formed so as to be butted against journal bearing faces F, i.e. a standard surface, are projected from both the ends of the movable plate 11 and the under surface of the thin-walled part 11d respectively and the movable plate 11 is lowered by the load of a main weight 21 and light weights 22 to measure the height of a work W.
