Wire feeding mechanism of laser welding rotary table

The utility model discloses a wire feeding mechanism of a laser welding rotary table. The wire feeding mechanism comprises a box body and a welding wire pretreatment mechanism installed on the side wall of the box body. Wherein a wire feeding assembly is mounted in an inner cavity of the box body; the welding wire pretreatment mechanism comprises a welding wire surface residue cleaning assembly and a welding wire surface deburring assembly fixed to the side wall of the bottom of an inner cavity of the metal box. On the basis of an existing welding wire feeding structure, the welding wire surface residue cleaning assembly and the welding wire surface deburring assembly are additionally arranged, a welding wire is pretreated before being fed and corrected, and the belt wheel rotates to drive the metal strips on the side wall of the inner cavity of the inner ring to rotate; therefore, the surface of the welding wire penetrating through the inner ring is polished, and the purpose of removing burrs on the surface
