Servo wire feeding structure

The utility model discloses a servo wire feeding structure, relates to the technical field of welding robots, and aims to solve the problems that an existing wire feeding mechanism for a welding robot is unstable in wire feeding, relatively poor in wire feeding accuracy and uncontrollable in wire feeding speed, and the situation that a welding wire is inconvenient to position and prone to deviation during wire feeding. According to the technical scheme, the wire feeding device comprises a wire feeding box fixedly arranged on a welding robot, a welding gun is fixedly installed on the outer wall of the bottom of the wire feeding box, and a servo wire feeding mechanism and a positioning mechanism are sequentially arranged in the wire feeding box. The servo wire feeding mechanism is designed, the wire feeding speed can be flexibly controlled through control of a servo motor, the wire feeding accuracy is improved, and the wire feeding stability is guaranteed through meshing transmission of a worm and a worm wheel;
