FIELD: the invention refers to measuring technique namely to special indicative devices for measuring inner dimensions of complex cavities profiles of different articles. ^ SUBSTANCE: the indicative device includes a measuring appliance with an indicator of clockwork type 2, fulfilled in the shape of an immovable body 3 and a spring-loaded pivot rod pivotally fastened on an axle 4. On the immovable body 3 there is a support 7, a stop end-face 8 and a limiting element providing measuring in a strictly definite plane. At that the end of the immovable body is fulfilled in the shape of a sphere, and the end of the pivot rod - in the shape of a direct edge under an angle of 950 relatively to the measuring plane. At that the dimension between the sphere of the body 3 and the edge of the pivot rod equals 2,0 mm. ^ EFFECT: provides measuring of complex cavities profiles in strictly prescribed cross sections to an approximation of 0,005 mm. ^ 4 dwg |
