Clamping and positioning device for self-piercing riveting of special-shaped section part

The invention discloses a clamping and positioning device for self-piercing riveting of a part with a special-shaped section. The clamping and positioning device for self-piercing riveting of the part with the special-shaped section comprises a base; the mounting plate is detachably connected to the base, and the mounting plate is provided with a profiling groove matched with the outer contour of a special-shaped section part; and the pressing mechanism is arranged on the base and used for pressing and fixing the special-shaped section part in the profiling groove. According to the self-piercing riveting, clamping and positioning device for the special-shaped section part, positioning and clamping of the special-shaped section part can be achieved, special-shaped section parts of other specifications can be rapidly matched with new-structure products by replacing the mounting plate, and universality is high. 本发明公开了一种用于异形截面零件自冲铆接夹持定位装置，该用于异形截面零件自冲铆接夹持定位装置包括：底座；安装板，可拆卸连接于所述底座，所述安装板设有与异形截面零件的外轮廓相适配的仿形槽；压紧机构，设于所述
