[0002] 3m 3 The uranium hexafluoride container series products are one of the main nuclear storage and transportation containers used in the nuclear fuel industry. Its main structure is three flat steel rings assembled on the middle cylinder, and the two ends are assembled with the head skirt assembly respectively. After the cylinder is manually rounded, the roundness deviation value is large, which will affect the quality and efficiency of the assembly of the flat steel ring and the cylinder, and the assembly of the head skirt assembly and the cylinder. In the past, simple mechanical tooling (which cannot rotate) was used to make the cylinder round. The labor intensity of the workers was high. The roundness of the cylinder was corrected to a certain extent, but there was a situation where the roundness exceeded the standard. The roundness control of the cylinder port has a great influence on the misalignment of the subsequent two annular seams. Therefore, it is necessary to use a hydraulic tooling assembly to make the cylinder round. In order to improve the 3m 3 In order to improve the quality and efficiency of the assembly of the flat steel ring of the uranium hexafluoride container and the cylinder, and the assembly of the head skirt assembly and the cylinder, and reduce the labor intensity of workers, it is necessary to design and develop a hydraulic circular rotation mechanism for the container cylinder.
