Description

Multifunctional gripper mechanism for uranium hexafluoride transport container full-automatic welding production line Technical Field The utility model belongs to the technical field of nuclear fuel processing equipment, and particularly relates to a multifunctional gripper mechanism for a full-automatic welding production line of uranium hexafluoride transport containers. Background Uranium is a rare radioactive element in nature, and the isotopic abundance of uranium-235 in natural ores is only about 0.7%. In order to meet the nuclear power demand, uranium-235 abundance needs to be improved through a uranium enrichment process (such as a gas diffusion process, a centrifugal process or a laser process), while uranium hexafluoride (UF 6) is used as a key medium in the uranium enrichment process, and the manufacturing quality of a transport container directly influences the production safety of nuclear fuel. The conventional uranium hexafluoride transport container manufacturing process has the following drawbacks: 1. the manual dependency is high, the domestic uranium enrichment factory generally adopts a manual operation crane to grasp, carry and assemble container parts, the efficiency is low, and the parts are easy to damage due to operation errors; 2. The welding quality is unstable, the manual welding rod arc welding process is greatly influenced by the technical level of personnel, the consistency of welding seams is poor, and the risks of defects such as air holes, unfused fusion and the like exist. Disclosure of utility model In view of the above, the utility model aims to provide a multifunctional gripper mechanism for a full-automatic welding production line of uranium hexafluoride transport containers, which solves the problems of high manual dependency and unstable welding quality in the manufacturing process of the traditional uranium hexafluoride transport containers by adopting a structure of a central positioning ring and a connecting rod and arranging a clamping cylinder around a jaw. The utility model provides a multifunctional gripper mechanism for a uranium hexafluoride transport container full-automatic welding production line, the multifunctional gripper mechanism for the full-automatic welding production line of the uranium hexafluoride transport container comprises a jaw base, a plurality of connecting rods, a center positioning ring, a plurality of clamping cylinders, a plurality of sliding seats and a plurality of jaws.
