DEVICE MEASURING THICKNESS AND THICKNESS DIFFERENCE OF HOLLOW CYLINDRICAL PART Russian patent published in 2004 - IPC

FIELD: measurement technology. SUBSTANCE: device includes base carrying column and bracket. Control bell-crank is installed in bracket. Axially movable disc interacting with bell-crank is put on column. Conical recesses are made over circumference of movable disc. Immobile disc with six grooves arranged over circumference and clamp are anchored on upper part of column. Each groove houses pair of measuring bell-cranks mounted for turn in groove around common axis. In this case one measuring bell-crank is mounted for turn around another measuring bell-crank and is spring-loaded. Measuring tips are put on ends of measuring bell-cranks in each pair and their other ends are positioned in conical recesses. Each pair of bell-cranks is provided with reading unit which case is made fast to non-rotary bell- cranks and its measuring bar contacts rotary bell-crank. EFFECT: expanded technological potential and enhanced operational characteristics of device. 2 dwg
