Abstract: A powder-enhanced friction stir rivet welding device includes a friction stir rivet welding spindle, a C-shaped frame and a tooling platform. The friction stir rivet welding spindle includes a rotating mechanism, a feed mechanism, a vibration-rotation mixing mechanism and a powder feeding mechanism. The friction stir rivet welding spindle is configured to realize rotation and feed movements of a rivet and feeding and mixing of a powder. The C-shaped frame is configured to fix the friction stir rivet welding spindle and the tooling platform. The tooling platform includes a force sensor, a sensor indenter, a tooling mould and a tooling platen. The tooling platform is configured to clamp a workpiece to be riveted and welded, and measure a rivet welding force of the friction stir rivet welding spindle in real time.
