环槽铆接工艺有其独特的优越性，在机械结构中得到了应用，环槽铆接的结构如图正所示。铆钉A和铆套B为铆接的基本元件，铆钉由两部分组成，带钉帽的称之为上部段，余者称为下部段，又称工艺柄。上、下两段间有供断裂用的缩颈，在上部段上刻有环状沟槽。铆套B的内、外表面均为光 Ring groove riveting process has its unique advantages, has been applied in the mechanical structure, ring groove riveting structure shown in Figure. Rivet A and Rivet B are the basic components of riveting. The rivets are made up of two parts. The upper part is called the upper part with the nail cap and the lower part is called the lower part. Between the upper and lower sections there is a necking for fracture, engraved with an annular groove in the upper section. Rivet B inner and outer surfaces are light
