Flexible assembling device suitable for welding and assembling of spliced welding type pipelines

Abstract

The invention relates to a flexible assembling device suitable for welding and assembling of spliced welding type pipelines and relates to the field of flexible guide pipe welding and assembling. Theflexible assembling device comprises a fence, six flexible supporting device combined parts, three x-axis direction guide rails and a base. The base is a platform which is horizontally placed. The fence is fixedly installed at the position of the side edge of the upper surface of the base in a surrounding manner. The three x-axis direction guide rails are evenly distributed on the upper surface ofthe base in the x direction. The six flexible supporting device combined parts are placed in parallel along the y axis, and the six flexible supporting device combined parts are arranged at the center position of the upper surface of the base. All the six flexible supporting device combined parts are arranged at the top ends of the three x-axis direction guide rails in a sleeving manner. The sixflexible supporting device combined parts can slide along the x-axis direction guide rails. By means of the flexible assembling device, the requirements for welding and assembling guide pipes with different specifications in different space walking directions are achieved, and accurate manufacturing and efficient manufacturing of spliced welding type guide pipes are achieved.

Description

technical field [0001] The invention belongs to the field of flexible conduit welding assembly, and relates to a flexible assembly device suitable for tailor-welded pipeline welding assembly. Background technique [0002] In launch vehicles and strategic and tactical weapons, according to the traditional pipeline product manufacturing mode, for non-sampling pipeline products that can be produced according to the theoretical dimensions of the drawings, special welding tools are usually used for production. For tailor-welded pipeline products with complex spatial structure, it is mainly tailor-welded from different components such as half-pipes, compensators, joints, flanges, straight pipe sections or reducing cones. In order to ensure the welding quality and reliability of pipeline products, each component of the conduit needs to be filed before welding to ensure a good butt joint at the butt joints and avoid excessive welding deformation or welding residual stress.

Problems solved by technology

[0003] Special welding fixtures limit the flexibility of adjustment: according to the function, structural characteristics and usage methods of special welding fixtures, different conduits require different special welding fixtures

Since the fixed special welding tooling limits the flexibility of adjustment, once the design and manufacture of the tooling is completed, it cannot be adjusted. Therefore, if the direction and length of the catheter product are adjusted, the special welding tooling needs to be reworked

[0004] The design and manufacture cycle of special assembly and welding equipment limits the rapid response: the special assembly and welding equipment has a long continuous cycle from design to manufacture

Once the catheter structure is adjusted, the rework or redesign of the special welding tooling cannot meet the needs of quick response of the catheter manufacturing

For the development model, this disadvantage is particularly prominent, which greatly restricts the rapid design, manufacture, verification and adjustment of pipeline products, and seriously affects the progress of model development

[0005] The change of the conduit structure will cause a serious waste of resources: if there is a change in the size and shape of the conduit, the original special welding tool cannot meet the requirements of the conduit assembly, which will lead to the scrapping of the original special welding tool, which will definitely cause a huge waste of resources

[0006] The application of special assembly and welding equipment brings great challenges to production management: with the increasing number of liquid launch vehicle models, the number of special assembly and welding equipment used for the production of tailor-welded conduit products is also increasing. It also brings great difficulties to production management
