The invention provides a wide-range rolling and posture adjusting device for a rocket section. The wide-range rolling and posture adjusting device for the rocket section comprises a foundation and rolling and posture adjusting devices located on the two sides of the foundation. Each rolling and posture adjusting device comprises an X-axis guide rail, a Y-axis guide rail, a Z-axis lifting device and a rolling pair. Each rolling pair comprises a U-shaped supporting base and a roller. By the adoption of the wide-range rolling and posture adjusting device for the rocket section, six-space-freedom-degree adjustment of the rocket section can be achieved, and 360-degree rolling of the rocket section can also be achieved; the overall length of the wide-range rolling posture adjusting device corresponds to the rocket section, and when the rocket section is placed, the requirement that a supporting point corresponds to the position, allowing supporting to be conducted, of a rocket body can be met without adjusting the position of the supporting point; according to the driving mode of wide-range rolling, active drive and following are combined, so that control difficulty is lowered, and the situation of inharmonious linkage is avoided; wide-range rolling and posture adjustment of rocket sections within a certain diameter specification range can be conducted through the wide-range rolling and posture adjusting device; the structure is simple and operation is easy.
