Abstract

The invention relates to a heavy water reactor component end plate detection tool comprising a base reference plate, support pins and positioning pins. Two symmetric groups of pin holes are distributed on the base reference plate and each group includes three pin holes which are arranged at equal intervals of 120 degrees. Support pins are installed in one group of pin holes and are used for accurately supporting the end plate and reducing wear of the base reference plate by the end plate. The positioning pins are installed in the other group of pin holes and are used for positioning the end plate. The base reference plate is made of a material with good light transmittance. The both sides of the detection tool are provided with three thread positioning holes for mounting an image detectorfor detecting the size of the end plate in order to ensure that the consistency that the detection tool install or uninstall the end plate multiple times. The heavy water reactor component end plate detection tool can achieve the following effects of 1) stably clamping twenty heavy water end plates to achieve rapid batch size detection; 2) positioning the part arc of the end plate and achieving accurate clamping position and good consistency.

Description

technical field [0001] The invention belongs to the field of detecting the size of end plates of nuclear power fuel components, and in particular relates to a tool for detecting the end plates of heavy water reactor components. Background technique [0002] The end plates of nuclear fuel assemblies for heavy water reactors are plate-shaped structures punched by stamping dies. Dimensional measurement and detection efficiency are low, which cannot meet the detection in the production process. Before the design of this inspection tool, the end plate inspection required operators to operate continuously. Using this tool, combined with a fully automatic imager, can realize the automatic inspection of 20 end plates, which greatly saves labor and inspection time. Contents of the invention [0003] The purpose of the present invention is: through the research and invention of the heavy water reactor fuel assembly end plate imaging instrument detection tool, the assembly end plate...
