Abstract

The invention belongs to the technical field of nuclear fuel element machining electromechanical integration, in particular relates to a spot welding and brazing integrated device of a nuclear fuel element cladding pipe. The device comprises a brazing system, a spot welding system, a feed mechanism, a discharge mechanism, a loading robot and an unloading robot, wherein the spot welding system performs the spot welding of a support pad and an isolation block on the cladding pipe; two robots are symmetrically mounted on the central surface of the brazing system; the feed mechanism and the loading robot are arranged at the feed side of the brazing system; the discharge mechanism and the unloading robot are arranged at the discharge side of the brazing system; and in working, the spot welding system works firstly to prepare materials for the brazing system. Two ABB robots are used as intermediate links, and the spot welding and the brazing are integrated as a whole, so that the automatic sequence transfer after the spot welding and the automatic discharge after the brazing of the cladding pipe are realized, the research on the nuclear fuel element manufacturing aspect is enriched, and the foundation of developing the fuel element manufacturing develops to the direction of integration and full automatization and reducing the inference of manmade middle link factors as far as possible is laid.

Description

technical field [0001] The invention belongs to the technical field of electromechanical integration of nuclear fuel element processing, and in particular relates to an integrated device for point brazing of nuclear fuel element cladding tubes. Background technique [0002] In the production of heavy water reactor nuclear fuel elements, in the traditional technical scheme, the automatic spot welding machine for the support pad isolation block and the single tube brazing machine are required to operate separately. Among them, the automatic spot welding machine for the support pad isolation block is used for the spot welding positioning of the support pad and the isolation block and the zirconium tube, and the single tube brazing machine is used for the brazing of the semi-finished product after spot welding, so that the support pad isolation block and the zirconium tube form a firm connect. Among the existing technical solutions, the international advanced heavy water reacto...
