Linear type three-coordinate coversion machine for testing satellite quality characteristics

The utility model provides a linear type three-coordinate conversion machine for testing satellite quality characteristics, principally including a platform assembly and a sliding table assembly, wherein the platform assembly principally includes straight-line guides, a ball screw assembly, a buttjunction disk, a body and a drive motor; the sliding table assembly principally includes a support, a rotating platform, a tilting platform, a tilting mechanism, a rotating mechanism and a booster spring. Compared with the existing arc type three-coordinate conversion machine, the utility model has better universality.
