DEVICE MEASURING DIAMETERS Russian patent published in 2001 - IPC

FIELD: instrumentation. SUBSTANCE: device has body housing guide in the form of dove tail, separable clip embracing guide with use of groove having shape of dove tail, mounted to move along guide and fix on it, indicator 12 with measurement rod 26, lamellar frame with sides placed vertically and separable bracket 21 put on face side of frame. Sleeves 13 of indicator 12 are anchored in body. Measurement rod 26 of indicator 12 is coupled with its ends to face sides of frame. One of measurement lugs 10 is located in clip, other lug 25 is positioned in bracket 21. Axis of measurement rod 26 of indicator 12 and axes of measurement lugs 10 and 25 are parallel one to another and lie in longitudinal symmetry plane of frame. Frame is mobile with reference to body in direction of its longitudinal axis and moves with the aid of pins attached to body and longitudinal grooves interacting with them. Frame is spring-loaded in longitudinal direction relative to body to both sides with the help of two studs with springs positioned in symmetry with regard to axis of measurement rod 26 of indicator 12 in plane horizontal with it. Holes to accommodate pins are made in face sides of frame, face walls of body have threaded sockets for their installation on one or another side of body while measuring internal or external surfaces correspondingly. Device is fitted with separable bracket and clip carrying measurement jaws. EFFECT: expanded range of measured diameters, widened technological capabilities. 1 cl, 12 dwg
