FIELD: machine building.SUBSTANCE: clamping device is intended for coaxial clamping of tool holder in rotating around axis (3) of rotation spindle of balancing machine. Connecting shaft (8) in receiving hole rests only in discrete support positions (11-15), which in radial direction have intervals and are in three spaced from each other, crossing axis (3) of rotation planes (E1, E2, E3) of grip. Four fixed discrete support positions (11-14) are arranged in pairs in first (E1) and second (E2) grip planes and together form fixed support in first radial direction. In located between first and second planes grip clamp of third grip plane (E3) fifth discrete support position (15) is formed, which provides support in second radial direction opposite to first radial direction.EFFECT: precise centering and clamping of tool holder in receiving hole of spindle.14 cl, 5 dwg |
