Abstract

The invention discloses a 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, a welding gun shaft assembly and a fixed sleeve fixed on the gun shell are arranged in the cavity, an electrification coil is arranged in the fixed sleeve, the front end of the welding gun shaft assembly is provided with an electric conduction chuck, the rear end of the welding gun shaft assembly is detachably connected to the fixed sleeve through an armature, the welding gun shaft assembly is coaxially sleeved with a shaft sleeve, the outer edge of the shaft sleeve is provided with a positioning rod extending outwards, the gun shell is provided with a hole clamped with the positioning rod, the armature isin a cross shape, and the fixed sleeve is provided with a cross hole matched with the armature. The welding gun disclosed by the invention has a compact structure, and the welding operation is easy. The stud welding height can be easily adjusted. The axis of an electric conduction shaft is accurately positioned so as to ensure a stud to be perpendicular to a welding plate.

Description

technical field [0001] The invention relates to a 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 welding pool on the workpiece to form a welded joint. . According to the d...
