TH53915A - Device and method for measuring hole contours - Google Patents

Abstract

DC60 (27/02/45) In 10 measuring instrument, arm 36 is lowered to insert a measuring sphere 30 into hole 22A in workpiece 22, and then the measuring sphere 30 is lowered in Direction of hole depth 22A.In this way, the back pressure of the compressed air is detected. At various locations by air / electricity conversion units, 18 measured values are compared with Main reference value by regulator 20 to convert the measured value into hole inner diameter 22A. In this way, the shape of the holes can be measured.
