The invention discloses a welding gun system adapting to a multi-diameter hollow stud and a welding method of the welding gun system. The welding gun system comprises a stepping motor unit, an electromagnetic arc stud welding gun, a gas claw unit, a radial symmetric magnetic field unit, a connection cover and three link mechanisms, wherein the electromagnetic arc stud welding gun comprises an electromagnetic coil, a movable iron core and a coil spring type automatic arc stud welding gun lifting structure; the electromagnetic coil is arranged on the movable iron core in a sleeving manner; the top of the movable iron core is connected with the stepping motor unit, and the bottom of the movable iron core is connected with the coil spring type automatic arc stud welding gun lifting structure; the gas claw unit is fixedly connected with the bottom of the coil spring type automatic arc stud welding gun lifting structure; the connection cover is arranged on the outer wall of the coil spring type automatic arc stud welding gun lifting structure in a sleeving manner; and the radial symmetric magnetic field unit is arranged below the gas claw unit and connected with the connection cover through the three uniformly distributed link mechanisms. The welding gun system provided by the invention solves the problem that a conventional welding gun system cannot realize automatic welding of a variable-diameter hollow stud, and can weld not only the variable-diameter hollow stud but also a solid stud.
Description
technical field [0001] The invention belongs to welding equipment, in particular to a welding torch system and a welding method for multi-diameter hollow studs. Background technique [0002] In modern industrial production, with the increase of labor costs and higher requirements for welding quality, in order to adapt to the changes in the intelligent welding environment of robots, the original manual stud welding gun must be improved. How to automatically clamp studs, How to control the lifting height of studs during welding, how to deal with hollow studs, etc., have become the key technologies of robotic stud welding. [0003] The welding of hollow studs is different from that of solid studs. Arcs cannot be generated by tip vaporization for welding. Only a radially symmetrical magnetic field is designed. In the magnetic field, arc electrons rotate under the action of Lorentz force. During the rotation, The arc will move along the hollow stud and the surface of the workpie...
