FIELD: mechanical engineering, may be used in copying-milling machines and measurement instruments. SUBSTANCE: copying apparatus has measurement rod positioned for resilient motion in axial and radial directions, radial flexible suspension of quasi-cylindrical form having basic, intermediate and resiliently movable parts interconnected through tie-rods. Points of connection of tie-rods to basic and resiliently movable parts of suspension are positioned in plane perpendicular to measurement rod axis. Intermediate part of suspension is offset relative to above mentioned plane along rod axis and is connected with resiliently movable and basic parts through tie-rods. Tie-rods have similar spatial flexible pivot joints located at joining points and are oriented along measurement rod axis. Tie-rod joining points in each joining plane are equally spaced along circle with center extending through axis of measurement rod, when latter is in the initial position. Tie-rods interconnecting intermediate and resiliently movable parts of suspension are alternating along circle with tie-rods interconnecting intermediate and basic parts of suspension. Radius of circle defined by flexible pivot and intermediate part joining points and of similar circle defined by flexible pivot, basic and resiliently movable parts jointing points, are unlike. Radial resilient suspension is made one-piece. EFFECT: increased efficiency, wider operational capabilities and enhanced reliability in operation. 3 cl, 10 dwg |
