FIELD: instrumentation.
SUBSTANCE: device contains inclined casing with two centring pins, rod installed in the inclined casing with possibility of progressive and reciprocal-turning movements around its longitudinal axis, measuring rod, rigidly secured on the rod, setting prism with work surfaces secured on the inclined casing and located by its bisector plane at right angle to the line connecting centres of the cross-sections of the centring pins, and equally spaced from the said centres, and reference assembly installed on the inclined casing with possibility of interaction by its measuring tip and rod. At that the setting prism is made and installed with possibility of its centring as per the work surfaces of the side spherical surface of the measuring probe. Rod is located with possibility of progressive movement in the direction parallel to line connecting centres of the cross-sections of the centring pins, and touch of the said surface of the measuring probe with side surface of the slot in their extreme points in the direction of the slot depth.
EFFECT: increased accuracy and possibility of parameters measuring of the slot not aligned with the part hole.
