MEASURING HEAD FOR PNEUMATIC MICROMETER HAVING OPENING/SHUTTING DEVICE OF BLAST AIR |
摘要 |
PURPOSE: A measuring head of a pneumatic micrometer having an opening/shutting device for blast air is provided to block blast air by arranging the opening/shutting device to the measuring head and to inject air only to measure inside and outside diameters. CONSTITUTION: A measuring head of a pneumatic micrometer having an opening/shutting device(15a) includes a body(5) injecting air to an inner peripheral surface of a tubular part and the opening/shutting device installed to the body to block blast air. The body has an air passage(3) injecting air toward a radial direction to measure a bore of the tubular part and an air supply hole to supply outer air. The opening/shutting device opens and shuts the air supply hole to pass or block air of the air passage. Therefore, a measuring portion measures pneumatic pressure of blast air in the tubular part and the bore is calculated.
