Compared with the prior art, the welding gun can freely swing within a narrow gap, so that a welding bead with a concave curved surface can be welded; and a tungsten electrode clamp is omitted, so that the tungsten electrode can be conveniently changed, the tungsten electrode can be dismounted only by unscrewing an external positioning screw, and the concentricity between the tungsten electrode and the nozzle is free from bias.
Description
Technical field
The utility model relates to electric welding equipment, specifically refers to a kind of argon-arc welding gun structure.
Background technology
The argon arc welding technology is on the basis of the principle of common electrical arc-welding; utilize argon gas to the protection of metal wlding; make wlding be melted into the liquid bath that forms at welded base material by high electric current; make welded metal and wlding reach a kind of solder technology of metallurgical binding; owing in the high-temperature fusion welding, constantly serve argon gas; wlding can not be contacted with airborne oxygen, thereby prevented the oxidation of wlding, therefore can soldering copper, the non-ferrous metals such as aluminium, steel alloy.
The argon arc welding that we often say generally refers to argon tungsten-arc welding, with the non-melt pole inert gas-shielded arc welding of tungsten electrode as the arc burning electrode.Argon-arc welding gun generally includes the parts such as rifle body, nozzle, tungsten electrode folder and tungsten electrode, and it is upper and pass described nozzle and expose that described tungsten electrode is clamped in the tungsten electrode folder, and described nozzle connects described tungsten electrode folder.Tungsten electrode is positioned at the center of nozzle, during arc burning, need all the time argon gas protecting around it, but it is again wearing detail, need to adjust and changes, so general argon-arc welding gun presss from both sides all being furnished with tungsten electrode, and fixedly tungsten electrode is convenient in the position of leaving suitable length.So, certainly will cause the length of tungsten electrode axis direction to increase.Present argon-arc welding gun of the prior art is used for the Narrow sloping-glot welding bead that weld width only has 18-20mm, and mouth is oversize, puts to good use not open when swinging in groove; Affected by angle, under the obstruction of nozzle, the tungsten electrode head can not be near the both sides mother metals, so that electric arc can't melt the both sides mother metal.If use the straight handle of small dimension instead, slightly bending usefulness, effect are also undesirable, still can not reach to melt the needed angle of mother metal fully, and the argon-arc welding gun of small dimension are through can't stand the welding of long-time large electric current.Importantly, adopt existing argon-arc welding gun can't in narrow gap, weld out the welding bead with recessed curved surface.
Summary of the invention
Technical problem to be solved in the utility model be the present situation for prior art provide a kind of current capacity large, be adapted at the argon-arc welding gun header structure that welding in the narrow space has lower concave curved surface welding bead.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this argon-arc welding gun structure, comprise the rifle body that is connected with handle, nozzle, with conducting element and the tungsten electrode of argon gas from rifle body water conservancy diversion to nozzle, wherein, described conducting element connects described rifle body and nozzle, and described nozzle cage is located at outside the described baffle; The axis that it is characterized in that described baffle becomes 20-30 ° of angle with the axis of described rifle body; Described nozzle cage is located at outside the described baffle and with baffle and removably connects; Described rifle body is provided with mounting groove; One end of described tungsten electrode is contained in the described mounting groove, and the other end of tungsten electrode passes described baffle and nozzle exposes.
Better, the axis of described baffle becomes 25 ° of angles with the axis of described rifle body.
Described baffle is threaded with described rifle body.
For making things convenient for the replacing of tungsten electrode, also be provided with screw on the described rifle body, screw passes this screw described tungsten electrode of conflicting.
The inner ring set of described nozzle is on described baffle, and the distance between the inner termination of described tungsten electrode external end head and described nozzle is 25-30mm.This structure can be adapted at using in the narrow gap better.
Described nozzle is threaded with described baffle.
Compared with prior art, argon-arc welding gun provided by the utility model stretches in the narrow gap with 45° angle, the angle of tungsten electrode and weld seam is 65 °-75 °, can centered by rifle body axis, freely swing back and forth, jet hole only has tens millimeters radius from the axis, the mobile radius of the electric arc that tungsten electrode produces is greater than the radius of nozzle, and the coverage of electric arc surpasses it self required locus of action, so just realized the demand of arc-melting both sides mother metal in narrow space fully; Simultaneously, because the motion track of electric arc is arc, the speed of its swing, track and both sides dead time can arbitrarily arrange by the welding gun controller, weld the welding bead that comes and become concave shape thereby make, and welding bead surface smoothing, decorative pattern are consistent, attractive in appearance.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model embodiment decomposition texture.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this argon-arc welding gun header structure comprises:
Rifle body 1, the employing hexagonal brass rod is made, the 25mm hexagonal is stayed at two ends, the remainder car becomes the cylinder of φ 15mm, the termination 12 that is connected with baffle 2 is processed into main body 11 parts and is become 25 ° of inclinations, be drilled with the screw thread mounting groove 13 of M10 on the termination 12 along axis direction, centered by mounting groove 13, the hexagonal re-surface of termination 12 become suitable circle.Also be provided with the screw 14 that connects with mounting groove 13 on the perisporium of termination 12.The specification of screw is φ 3mm in the present embodiment.
