Mounting positioning type riveting-turning self-locking nut

A mounting positioning type riveting-turning self-locking nut is formed in an overall heading mode. The two sides of a nut head portion are riveting-turning positions, the oblique lower position of the nut head portion is a riveting-turning limiting position, the position under the nut head portion is a mounting position, and an outer convex position below the mounting position is a mounting limiting position. A closing-up position is arranged below the retraction portion of the mounting limiting position. A squeezing mode is used for tapping threads, the strength of the threads of a product is enhanced, the detachable times of the nut is increased, and an MoS2 dry-film lubricant coats an inner thread of the nut to prevent excessive-tight meshing. The mounting position and the riveting-turning positions are mainly used for tightly fastening a mounting plate and an insulation plate together in a riveting-turning squeezing mode through the nut before assembling, then the mounting plate is connected to a base body through the self-locking nut, and a self-locking mechanism on the nut replaces a spring gasket. In the mounting process, special process equipment and device are used for mounting the nut on the base body first, the nut and the base body are integrally connected, when a product is assembled, a bolt or a screw only needs to be screwed in the nut, and automation can be achieved.
