The invention relates to a nut riveting head. The nut riveting head is characterized by comprising a limiting sleeve and a riveting body which is arranged inside the limiting sleeve in a sliding mode. A limiting strip-shaped through hole is transversely formed in the limiting sleeve, the lower end of the limiting sleeve is provided with a cup joint port with the diameter consistent with the diameter of the inscribed circle of the cross section of a nut, a connecting through hole is transversely formed in the riveting body, the limiting strip-shaped through hole is communicated with the connecting through hole, a hinge pin penetrating through the limiting sleeve and the riveting body is arranged inside the connecting through hole, the upper end of the riveting body is provided with a connecting structure connected with a riveting machine, the lower end of the riveting body is provided with a riveting plane formed by connecting a horizontal section and an inclined section, and the riveting plane is in an arc-shaped protruding shape. The nut riveting head is simple in structure and good in riveting effect.
Description
technical field [0001] The invention relates to the technical field of automobile assembly riveting, in particular to a nut riveting head. Background technique [0002] In the automobile assembly process, hundreds of parts are involved, and nuts are one of the most used parts in the assembly process as fasteners. According to the characteristics and requirements of automobile assembly, automobiles are usually assembled with nuts Tighten it with a larger torque, and riveting the nut, that is, riveting the flange of the nut into the shaft end groove of the shaft that matches the nut, so as to prevent the nut from loosening. At present, this process is mainly performed manually by knocking and riveting or using a riveting machine. Manual riveting is labor-intensive and low in efficiency. However, due to the complex and unreasonable structure of the riveting head of the riveting press, the riveting effect is poor. , so the nut riveting head is also a direction of research in ri...
