Description
Technical Field
The invention relates to the field of nuclear fuel element manufacturing, in particular to a nuclear fuel assembly spacer grid inspection gauge.
Background
The grid cells in the nuclear fuel assembly belong to a square thin-wall tubular structure, four planes and four arc surfaces are symmetrically processed on a thin wall surface, a thin-wall round tube is extruded and molded by a mold, the precision requirement is high, the requirement of large-scale production needs to be met, and no process equipment for punching and processing the grid cell tubes of the positioning grid frame and no punching method are established at present. The special punching die is designed and the punching method is established based on the reasons to solve the problem.
Disclosure of Invention
The invention aims to: in order to meet the requirements of the technical conditions of grid inspection, enhance the control capability of the production process of the grid, and improve the inspection efficiency and the production efficiency, a set of special gauges suitable for the inspection of the spacer grids needs to be manufactured so as to meet the requirements of the test and the production of the subsequent grids.
The technical scheme of the invention is as follows: the utility model provides a nuclear fuel assembly spacer grid inspection gauge, includes the installation base, and the installation base is connected with measuring the bottom plate, and the installation base bottom is placed in the workstation top, measures the bottom plate and is connected with measuring the frame, measures the frame and is connected with measuring the frame.
The mounting base is connected with the measuring bottom plate through bolts.
The measuring bottom plate is connected with the measuring frame through bolts.
The measuring bottom plate is taken out independently for replacement after being used for a long time.
The measuring frame is connected with the measuring upper frame through bolts.
The invention has the following remarkable effects: by using the manufactured special inspection gauge, the grid inspection capability is improved, the process inspection level is improved, and the quality of a final product is ensured. The manufacturing of the special check gauge for the grillwork is completed, the check project and the technical requirements of the grillwork are formulated, a complete grillwork check method is established, the manufacturing capability of the fuel assembly spacer grillwork is further improved, and the technical guarantee is provided for the future production and manufacturing of the grillwork.
