FIELD: measurement technology.
SUBSTANCE: invention relates to measurement technology, in particular to devices for measuring the width and the position of grooves at details, primarily for measuring parameters of hinge fork groove. The device comprises an inclined body, a set-up prism and a basic prism installed in a common bisector plane, a rod with a measuring probe installed on the inclined body in such a way that it is capable of forward motion along the longitudinal axis thereof and of reciprocating and reciprocating rotational movements around said axis. A measuring unit is installed on the inclined body arranged in such a way that it is capable of interacting with its measuring cap with the rod. The rod is installed in such a way that it is capable of touching the lateral spherical surface of the measuring probe with the lateral surfaces of the groove in their endpoints in the direction of the groove length and centering a basic prism along the working surfaces.
EFFECT: technical result consists in increasing the accuracy of measurement.
