Problems solved by technology
[0003] The present invention can only be applied to the assembly and welding of one section of the cylinder body and the head in view of the prior art, and cannot realize the assembly between multiple cylinder sections, or the flexibility of the tooling is insufficient, and the active shape comparison and local positioning cannot be performed, and the assembly accuracy of the workpiece is very low. It largely depends on the manufacturing and installation positioning accuracy of the arc brace, lacks clamping devices, and is difficult to apply to the friction stir welding welding process with strict requirements on tooling and fixtures. A vertical assembly device for cylindrical components is proposed

A vertical assembling device for cylindrical components comprises a rack, a vertical lifting platform used for lifting the cylindrical components, a friction stir welding mechanism, an annular upper outer clamp, an annular lower outer clamp and a horizontal feeding mechanism, wherein the vertical lifting platform, the upper outer clamp and the lower outer clamp are vertically and glidingly arranged in the rack sequentially; the friction stir welding mechanism is glidingly arranged on the lower outer clamp and can circumferentially slide along the lower outer clamp, and the horizontal feeding mechanism is arranged below the lower outer clamp. With adoption of a vertical assembling and clamping welding mode, structure deformation caused by gravity of the cylindrical thin-walled components is effectively avoided, and error factors in the assembling process are reduced; flexible assembling and clamping of the thin-walled cylindrical components are realized by use of the circumferentially distributed clamps, the positioning accuracy is guaranteed, positioning errors for assembling and clamping are reduced, the device is high in automation degree, has concentrated stations and occupies a small area, the height in processes of loading, assembling and clamping, welding and discharging is controllable, and the assembling efficiency is improved.
Description
technical field [0001] The invention relates to a technology in the field of automatic assembly, in particular to a vertical assembly device for cylindrical components. Background technique [0002] The high-precision assembly of large cylindrical thin-walled components is a key technology in aerospace and other fields. Aerospace thin-walled cylindrical components such as rocket storage tanks are tailor-welded with aluminum alloy thin-walled components in the form of grids in order to reduce their own weight. The assembly of large cylindrical thin-walled components mainly adopts horizontal assembly. The internal support fixture overcomes the deformation of the cylinder due to its own weight. It will increase, the cylinder structure is more seriously deformed by its own weight, and the horizontal assembly is more difficult to control the deformation of the cylinder. At the same time, the force in each direction is uneven, resulting in a decrease in positioning accuracy. Co...
