Ultra-large-diameter tube section shell and cross beam high-precision sleeving tool

Abstract

The invention relates to the technical field of part assembling, and particularly discloses an ultra-large-diameter tube section shell and cross beam high-precision sleeving tool. The ultra-large-diameter tube section shell and cross beam high-precision sleeving tool is matched with a riveting fixture to assemble a tube section shell and a cross beam of a first-stage post transition section of a heavy-lift carrier rocket, and comprises guiding cones arranged on a lower end frame of the tube section shell, guiding vertical columns arranged on the riveting fixture, guiding sliding rails arrangedon the guiding vertical columns and guiding seats capable of sliding along the guiding sliding rails. According to the ultra-large-diameter tube section shell and cross beam high-precision sleeving tool, high-precision sleeving of the tube section shell and the cross beam can be achieved, shell deformation is reduced, screw connection of the tube section shell and the cross beam is prepared, theform and position sizes after assembling is completed are guaranteed, and the problems that sleeving cannot be conducted, and the tube section shell is damaged are avoided.

Description

technical field [0001] The invention belongs to the technical field of component assembly, and in particular relates to a high-precision set tool for a super-large-diameter cylinder section shell and a well-shaped beam. Background technique [0002] The heavy-duty launch vehicle - the Long March 9 launch vehicle was first proposed in 2012 to meet the needs of my country's future moon landing, Mars sample return and exoplanet exploration missions. At present, the heavy-duty launch vehicle has completed in-depth demonstration and is expected to make its first flight within 15 years . The diameter of the Long March 9 rocket is nearly 10 meters, and the total length of the rocket is nearly 100 meters. Its carrying capacity is more than five times that of existing rockets. The transition section after the first stage is an important load-bearing section of the rocket. The casing of the shell section riveted by the skin frame truss structure and the well-shaped beam welded by stee...

AI Technical Summary

Problems solved by technology

However, if the well-shaped beam is assembled with the casing after the assembly of the casing of the barrel section is completed, due to the large diameter of the two, the fittings are not synchronized, and it is easy to cause the problem that the fitting cannot be installed and the casing of the barrel section will be damaged.
