Zusammenfassung:The invention discloses an aero-engine blade intake and exhaust edge thickness measuring device which comprises a support. The mobile measuring plate is in sliding connection with the bracket; a digital display meter is arranged on the movable measuring plate; the distance limiting plate is detachably connected with the bracket, and an arc for positioning the blade is formed on the distance limiting plate; the measuring pin is used for placing and measuring an air inlet edge or an air outlet edge of the blade; the positioning mechanism comprises a first positioning pin which is arranged on the bracket and is positioned below the distance limiting plate, and a second positioning pin which is arranged on the movable measuring plate and is arranged on the same straight line with the first positioning pin; the point where the second positioning pin slides to be in contact with the first positioning pin is the zero point of the measuring device; the circle center corresponding to the arc coincides with the zero po
