DEVICE FOR MEASURING DISTANCE BETWEEN HOLE CENTRELINES IN CASE WORKS

摘要

FIELD: measuring instruments.;SUBSTANCE: device for measuring the distance between hole centrelines of case works includes a housing, prisms, one of which being fixedly attached to the housing and another is mounted to one of the ends of a swing arm, fixing members and indicating instruments. The device is provided with two additional prisms, one of which being fixedly mounted at the opposite side of the housing asymmetrically towards the fixed prism with respect to the horizontal centreline and another - at the free end of the swing arm and it is disposed in the same plane as the fixed prism.;EFFECT: extending functional capabilities of the device, enabling to measure two different distances between hole centrelines by means of one measuring instrument.;5 dwg
