A large-range roll attitude adjustment device for rocket sections

Abstract

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.

Description

technical field [0001] The invention belongs to the field of mechanical assembly, and in particular relates to a large-range roll attitude adjustment device for a rocket section. Background technique [0002] In the assembly of the launch vehicle, it is necessary to roll along the axis in a large range to realize the installation of parts on the section; in the assembly between sections, it is necessary to adjust the six degrees of freedom of the section, which is It is necessary to design special tooling to meet the work requirements. At present, the large-scale rolling and attitude adjustment of the launch vehicle requires the use of a rolling frame and an attitude-adjusting frame respectively, which leads to a large area of ​​the workshop occupied by the special frame, and the mutual hoisting of the rocket body needs to be carried out when changing positions, and the working process consumes a lot of energy. Time consuming. [0003] At present, the general assembly of a...

Problems solved by technology

The increase in product size increases the difficulty of visual adjustment and the synchronization of roll and position adjustment; the increase in product quality causes a certain gravity deformation of the rocket body section, increases the position deviation of the docking hole, and is difficult for manual Rolling and repositioning pose great difficulties

Therefore, as the diameter of the rocket increases, if manual docking is still used, it becomes more and more difficult to observe, move, roll, and adjust the attitude of various sections such as the rocket body tank and the inter-box section during the assembly process.
