APPARATUS FOR THREE-DIMENSIONAL ORIENTATION OF ARTICLES Russian patent published in 2002 - IPC

FIELD: machine engineering, possibly three-dimensional orientation of objects, for example of adjustment table for precision working of parts in metal cutting machine tools. SUBSTANCE: apparatus includes elastically joined one with another basic member 1 and member 2 to be oriented. Central assembly and controlled peripheral supporting units 3,4 having spherical supporting members 5 are arranged between members 1 and 2. Apparatus also includes means for fixing three- dimensional position of member 2. Centers of spherical supporting members 5 of each supporting unit 3,4 are arranged in apexes of triangle, mainly right triangle. Each peripheral supporting unit 4 is in the form of two hemispheres 14,15. Adjusting wedge-profile member 16 is mounted with possibility of motion between spherical surfaces of said hemispheres. Hemisphere 14 is rigidly secured to basic member 1; hemisphere 15 is kinematically joined with member 1 through spring-loaded lever 17. Means for fixing three-dimensional position of member 2 are in the form at least of three fixing units 6 arranged along periphery of apparatus. EFFECT: improved reliability of rigid fixation of article. 2 cl, 2 dwg
