Robot wire filling friction stir welding and solid-phase material adding device

The invention discloses a robot wire filling friction stir welding and solid-phase material adding device which comprises a robot, a robot friction stir welding main shaft arranged on the robot, a main shaft control device, an industrial personal computer, a robot control device, a welding workbench and a push-pull wire feeder. The robot friction stir welding main shaft comprises a friction stir welding main shaft body, a reducing sleeve, a cutter handle, a locking fixing sleeve and stirring heads, and the stirring heads are divided into a wire filling welding stirring head and a wire filling additive stirring head. On the basis that a heavy-load robot drives a friction stir welding main shaft to do welding motion, a spiral milling cutter of a stirring head crushes and granulates wires fed by a push-pull wire feeder, and the wires are fed to a welding area and an additive area through a material guide thread of a stirring needle, so that robot wire filling friction stir welding and robot wire filling solid-ph
