Automatic rolling device for large-diameter long-section hollow cylinder

Abstract

The invention provides an automatic rolling device for a large-diameter long-section hollow cylinder, and belongs to the field of assembly equipment. The automatic rolling device comprises a rolling ring and at least two rolling frame vehicles, the rolling ring is fixedly arranged on the outer ring of a cylinder, the rolling frame vehicle comprises an arc-shaped supporting plate, a guide groove isformed in the upper end of the supporting plate, a rolling wheel rotationally connected with the guide groove is erected in the guide groove and drives the rolling ring to rotate along the axis of the rolling ring, the rolling ring is arranged in the guide groove and tangent to the rolling wheel, a plurality of positioning holes are formed in the rolling ring, a telescopic A-axis positioning mechanism is arranged outside the supporting plate, and the A-axis positioning mechanism extends into the positioning hole in an extending state. By the device, angle and axial positioning can be achieved, the rolling risk caused by eccentricity of rocket products and the difficulty of rolling ring installation caused by structural interference of the rocket products are overcome, the efficiency of carrier rocket general assembly is effectively improved, and the quality of carrier rocket assembly and the safety of workers in work are guaranteed.

Description

technical field [0001] The invention belongs to the field of assembly equipment and relates to the assembly process of large parts in the aerospace field, in particular to an automatic rolling device for a large-diameter long-section hollow cylinder. Background technique [0002] At present, the general assembly of my country's launch vehicles before leaving the factory adopts a single-section horizontal assembly, and then a horizontal combined docking form. The single section of the rocket is placed on the profiling bracket, and the operator carries out internal and external inspection of the rocket through the working ladder. Assembling, the shape of the rocket is relatively large, which belongs to the hollow cylinder structure with large diameter and long section. The maximum diameter of the active rocket is 3.35m, which can meet the assembly requirements through a simple working ladder. It can reach 30m, and the external assembly work of the launch vehicle can be satisfied...

AI Technical Summary

Problems solved by technology

However, it is difficult to operate the final assembly work inside the launch vehicle box and the shell section. The main reasons are: 1. The operating space inside the launch vehicle box and the shell section is narrow; 2. The product assembly is a high-altitude operation, and the accessibility is not enough. Existence, the current general assembly scheme is: operate by stepping on the relevant parts that can bear the force, or assemble the special working ladder in the box, not only there is a risk of damaging the product, but also the assembly of the special working ladder takes a long time and the work efficiency is low

[0003] At present, rolling assembly has been realized for shorter launch vehicle sections, but the current rolling assembly device is manually adjusted, and the rolling can only be oriented, not quantitative, and due to limited manpower, it cannot meet large diameter and super long sections. roll assembly requirements for
