Embodiment Construction
[0031] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0032] like figure 1 , figure 2 , image 3 , Figure 4 As shown, the assembly tooling of the deep-sea pressure-resistant structure of the present invention is a hollow spherical frame structure, and the hollow spherical frame structure is formed by splicing twelve regular pentagonal frames 1 and twenty regular hexagonal frames 2 with equal sides. , each regular hexagonal frame 2 is connected with three regular pentagonal frames 1 and three regular hexagonal frames 2 arranged at intervals; twelve regular pentagonal frames 1 and twenty regular hexagonal frames 2 is formed by splicing sixty joints 3 and ninety pipe fittings 4 . The joint 3 includes a spherical body 301 and three taps 302 arranged on the periphery of the spherical body 301. Among the three taps 302, the angles between two adjacent taps 302 are 120°, 120° and 108° respecti...

The invention discloses an assembly tool of a pressure resistant structure of a deep sea spherical shell and a forming method thereof, and belongs to the technical field of assembly and forming of large deep sea equipment. The assembly tool of the pressure resistant structure of the deep sea spherical shell is a hollow spherical frame structure; and the hollow spherical frame structure is spliced by sixty joints and ninety pipes according to the football structural rules, that is, each of regular hexagon frames is connected with three regular hexagon frames with the same edge lengths and three regular pentagon frames with the same edge lengths at the periphery. The forming method of the pressure resistant structure of the deep sea spherical shell finishes the assembly of the pressure resistant structure of the spherical shell through the spherical shell assembly process of assembly fixture-assembly spherical shell sectioning-welding forming; and the method can accurately and quickly perform the positioning assembly, is low in welding workload, and is convenient to maintain. A football sectioning type forming process is organically combined with a spherical frame assembly tool, so that the assembly operation is convenient, and the formed spherical shell is stable in structure; and the assembly tool can be recycled for assembling the spherical shell.
Description
technical field [0001] The invention relates to the technical field of assembly and molding, in particular to an assembly and molding technology of a spherical shell pressure-resistant structure, and in particular to an assembly tool and a method for assembly and molding of a deep-sea large-scale spherical shell pressure-resistant structure. Background technique [0002] The "deep-sea space station" currently under research is the development direction of large-scale deep-sea equipment in the future, and the spherical shell pressure-resistant structure is a key component of deep-sea equipment. The existing spherical shell pressure-resistant structure generally adopts the hemispherical forming process, that is, directly punches a hemisphere through a large-scale thick plate, and then welds the equatorial joints of the two hemispheres, but the forming scale of this forming process is small (diameter about 2m ~ 3m), It is difficult to reach the level of large-scale deep-sea sph...
