FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring techniques, in particular to devices for measuring the width and deviation from the symmetry of the groove made at the end of the bushing. Device for measuring the parameters of the groove on the end of the sleeve contains a body with two locating dowels and a reference assembly fixed to the body with a measuring rod. Device is further provided with a reference assembly fixed in the housing, in addition, the adjusting pins are designed and arranged to be touchable with the bore of the bushing. Counting units are placed on opposite sides of the plane passing through the longitudinal axes of the locating dowels and with the possibility of touching their measuring rods with the side surface of the groove to be measured at the points on the ends of the given surface.
EFFECT: increased productivity and accuracy of measurement.
