Split arcing type stud welding gun

Abstract

The invention discloses a split arcing type stud welding gun, which comprises a gun shell and an end cover group arranged on the gun shell, wherein a cavity is formed in the gun shell and the end cover group, an electric conduction shaft, a connecting body, an insulation sleeve, a male connection sleeve and a female connection sleeve are arranged in the cavity, the front end of the electric conduction shaft is provided with an electric conduction chuck, the female connection sleeve is fixed on the gun shell, an electrification coil is arranged in the female connection sleeve, the electric conduction shaft, the connecting body, the insulation sleeve, the male connection sleeve and the female connection sleeve are in split structures, the rear end of the electric conduction shaft, the connecting body, the insulation sleeve and the front end of the male connection sleeve are sequentially connected, the rear end of the male connection sleeve is provided with a magnetic armature, and the armature is inserted in the female connection sleeve in a relatively sliding mode. The split arcing type stud welding gun disclosed by the invention has a compact structure, and the welding operation is easy; the stud welding height can be simply adjusted; the axis of the electric conduction shaft is accurately positioned, and a stud is ensured to be perpendicular to a welding plate; the adsorptionand separation processes of the male connection sleeve and the female connection sleeve are quick and stable, the electric conduction shaft jumps slightly, and the welding quality is stable.

Description

technical field [0001] The invention relates to a drawn arc stud welding torch, in particular to a split drawn arc stud welding torch. Background technique [0002] Arc stud welding (stud welding) is a method of contacting one end of the stud with the surface of the plate (or pipe), energizing the arc, and after the contact surface is melted, a certain pressure is applied to the stud to complete the welding. Cylindrical head welding studs for arc stud welding are suitable for high-rise steel structure buildings, industrial plant buildings, roads, railways, bridges, towers, automobiles, energy, transportation facilities, airports, stations, power stations, pipe supports, hoisting machinery and Other steel structures, etc. [0003] The basic principle of arc stud welding is to ignite the arc between the stud to be welded and the workpiece. When the stud and the workpiece are heated to a suitable temperature, under the action of external force, the stud is sent into the weldin...
