GAUGING AND CALIBRATION INSTRUMENT Russian patent published in 2008 - IPC G01L25/00 

FIELD: instrument engineering.

SUBSTANCE: invention is referred to torque moment definition and may be used for torque wrench manufacture, maintenance and definition of action range. Gauging and calibration instrument for torque wrenches contains hinges, dynamometer, cinematic elements, which are in rotary connection with instrument body. Supports, two position adjusters, tensioner and loader with displacement capability are mounted on instrument body. In addition, instrument body is supplemented with mutually perpendicular guides. Loader ensured with displacement capability is mounted onto longitudinal guides, whereas tensioner is positioned on the others guides in the middle part of instrument body. One end of tensioner is connected with functional system of dynamometer and the other is provided with rocker linking a couple of pins. Rocker is fixed orthogonally with cinematic elements in one plane. Cinematic elements are represented with a pair of L-shaped levers, which adjoining ends are provided with shaped opening. Openings interact with rocker. The other ends of levers are at the opposite ends of body in bearing supports having parallel axes orthogonal to dynamometer plane and connected with adjusters. Each adjuster is provided with seat and bushing, which can be joined in mutual quick-release faceted catching, for example, toothing. Besides, bushing has faceted opening fitting the size and shape of connected element of removable calibrated torque wrench. Shaped openings at adjoining ends of Ll-shaped levers are in the form of triangle directed to the other side from rocker.

EFFECT: improvement of accuracy and instrument compactness.
