УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ДВУГРАННОГО УГЛА

摘要

FIELD: measurement technology. ^ SUBSTANCE: device has movable re-arranging rods, which are mounted inside case and brought into contact with sides of angle. The rods are made in form of two curved straight prismatic plates having rectangular cross-section and connected to each other by means of telescopic joint. There is longitudinal slot in embracing plate. Embraced plate enters the slot for reciprocal motion and location of plates relatively each other. Side faces of embraced plate are provided with angular scales to read angle out. Angle is marked by surface of edge part, which embraces plates when there is the contact of four long ribs of edge parts of both plates with surfaces of sides of two-sided angle. ^ EFFECT: improved precision of measurement; simplified design. ^ 2 dwg
