APPARATUS TO MEASURE RECTILINEARITY OF CYLINDRICAL HOLE AXIS

摘要

FIELD: measuring equipment, apparatus is used to measure rectilinearity (bending) of cylindrical hole axis of small diameter long pipes. SUBSTANCE: apparatus provides accuracy of cylindrical holes axes rectilinearity measurement due to the fact, that rectilinearity of measured hole own axis is defined. For the purpose body of apparatus is combined of two spring-loaded in respect to each other self-centering parts. In the case one part of body has flat flange and another one has contacting flange mushroom-shaped piece mounted with capability of interaction with inductive converter. Apparatus has telescopic handle to provide capability to measure rectilinearity of long cylindrical holes axis. EFFECT: apparatus provides accuracy of cylindrical holes axes rectilinearity measurements. 3 cl, 2 dwg
