Abstract
The invention discloses an argon-arc-welding welding gun which comprises a welding gun base body (1) and an argon nozzle (2) connected with the welding gun base body (1), wherein the argon nozzle (2) is located below the welding gun base body (1); the argon-arc-welding welding gun further comprises an electrode (3) which is fixedly connected inside the welding gun base body (1) and stretches out of the argon nozzle (2); the argon-arc-welding welding gun further comprises a transparent argon protective cover (3) which is connected to the welding gun base body (1); and the electrode (3) stretches out of the argon protective cover (3). The argon-arc-welding welding gun has a simple and reasonable structure and can effectively isolate air from a welding region, so that the welding quality is improved and the strong practical applicability is realized.
Description
Technical field
The invention belongs to the welder field, relate in particular to a kind of argon arc welding gun.
Background technology
Argon arc welding is called again the argon shield weldering.Be exactly to lead to argon fox protective gas around the arc welding, air insulated outside welding zone, is prevented the oxidation of welding zone; Because the argon arc welding arc stability, during welding moulding attractive in appearance, the non-welding surface slag is out of shape little weld seam fine and close, is widely used in during practice produces.Yet find in practice, the phenomenon of burning and crackle around the welding zone that traditional argon-arc welding gun welded, often can occur.Its reason is that the argon gas that welding gun ejects can not be effectively isolated outside with air, thereby has caused the oxidation of welding zone, has had a strong impact on the quality of welding.In order to improve welding quality, often can adopt the raising argon flow amount, play the purpose of air insulated outside welding zone.But this mode has caused the waste of argon gas, when argon flow amount is excessive, may make the argon shield air-flow form turbulent flow simultaneously, and air is involved in the protection zone, has reduced on the contrary the protection effect.
Summary of the invention
Purpose of the present invention is the shortcoming that overcomes prior art, provides under a kind of prerequisite not wasting argon gas, can effectively air effectively be isolated in the outer welding gun of welding zone.
For solving the problems of the technologies described above, technical scheme of the present invention is specific as follows:
A kind of argon arc welding gun comprises welding gun matrix and connected argon gas nozzle, and described argon gas nozzle is positioned at the below of welding gun matrix, also comprises an electrode, is fixedly connected on the welding gun matrix inner, and stretches out outside the argon gas nozzle;
It is characterized in that: also comprise a transparent argon protecting cover, be connected on the welding gun matrix;
Described electrode stretches out outside the argon protecting cover.
Further, adopt screw to be connected between described argon protecting cover and the weldering welding gun matrix, the overall structure of described argon protecting cover is cylinder-shaped, and described cylindrical shell is arc-shaped convex in the side in close its exit.
Further, adopt screw to be connected between described argon protecting cover and the welding gun matrix, the structure of described argon protecting cover is cone, less one open-ended of diameter, and the end face that diameter is larger seals and is connected with described welding gun matrix phase.
Further, described argon protecting cover bottom is connected with described welding gun matrix, and described screw is even circumferential and arranges on argon protecting cover cylinder body bottom plane.
Of the present invention simple and reasonable, can effectively air be completely cut off outside welding zone, thereby improve the quality of welding.
Description of drawings
Fig. 1 is the structural representation of the first embodiment of the present invention.
Fig. 2 is the structural representation of the second embodiment of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes welding gun matrix 1, with connected argon gas nozzle 2, one electrode 3 is fixedly connected on the inside of welding gun matrix 1 and stretches out outside the nozzle 2, also comprise a transparent argon protecting cover 4, described argon protecting cover 4 is whole cylindrical, but is arc-shaped convex 4a in the cylinder sides near its outlet; To guarantee that simultaneously electrode 3 heads will be exposed at outside the described cylinder protective cover 4; When argon gas sprays from nozzle 2; the argon protecting cover 4 that is arranged on nozzle 2 outsides can prevent effectively that argon gas is to diffusion all around; only be confined to the neighboring area in protective cover 4 exits; the protruding 4a of the circular arc in cylinder exit plays the argon gas that can make ejection and obtains good air-flow, thus better with air insulated outside welding zone.
As the second embodiment of the present invention; as shown in Figure 2; described argon protecting cover 4 is cone; the sealing of the larger end of diameter also is connected with the welding gun matrix phase, and the end that diameter is less opens wide, from the argon gas of nozzle ejection because the effect of the cone protective cover 4 of outside; can effectively gas be converged to the cone exit; form powerful argon stream in the exit, thereby air is completely cut off outside welding gun, improved welding quality.
Below only be two better embodiment of the present invention, do not limit to and the present invention.
