Description

Be used for the welding gun that the gas-shield automatic welding tipping is put

Technical field:

The utility model relates to a kind of annex of welding equipment, and particularly a kind of gas-shield automatic welding that is used for is hinged with the welding gun of putting.

Background technology:

CO ₂Gas shielded arc welding is owing to simple to operate, the good machine industry that is widely used in of appearance of weld; the mode one of welding is manual operations; the 2nd, adopt automatic soldering device; but the welding gun of automatic soldering device use all is the welding gun of manual welding mostly at present; promptly the manual welding gun of band handle is directly installed on the automatic soldering device and uses; the problem one that exists is to install and use inconvenience; the nozzle throat area of this type of welding gun generally all is circular in addition, is not easy to put in the small space butt welded seam and implements welding automatically (referring to Fig. 6～Fig. 7).

The utility model content:

The technical problems to be solved in the utility model: provide a kind of easy to install, can to the weld seam of small space implement welding, be used for the welding gun that the gas-shield automatic welding tipping is put, to overcome the prior art above shortcomings.

The technical scheme that solves the problems of the technologies described above is: a kind of gas-shield automatic welding that is used for is hinged with the welding gun of putting; comprise welding gun seat, escape pipe and go out fiber tube; the top of described welding gun seat is an arc supporting face; there is the convex of a band pore at arc supporting face rear portion; described escape pipe and wire vent tube side-by-side are fixed on the arc supporting face; the front end that goes out fiber tube connects ignition tip; going out the fiber tube tail end is communicated with the pore of convex; the other end of convex pore is the interface that is connected with the wire feed conduit, and the tail end of escape pipe is communicated with total pipe joint of supplying gas.

Further technical scheme of the present utility model is: described escape pipe is 1, and the front end of escape pipe has a radian that bends towards ignition tip, and the tail end of escape pipe is communicated with total pipe joint of supplying gas.

Further technical scheme of the present utility model can also be: described escape pipe is two, two escape pipes be positioned at fiber tube about, be fixed on the arc supporting face side by side, the front end of two escape pipes has a radian that bends towards ignition tip respectively, tail end or be communicated with or close up the back with two total pipe joints of supplying gas respectively and be communicated with total pipe joint of supplying gas.

Owing to adopt technique scheme, the welding gun that the gas-shield automatic welding tipping puts that is used for of the utility model has following beneficial effect:

1, since the welding gun of the utility model go out fiber tube and escape pipe is installed on the same arc supporting face side by side; the nozzle that the ignition tip of welding gun and the mouth of pipe of giving vent to anger are constituted is pancake; about the front end of two escape pipes bend towards ignition tip; not only help welding fusing point and form good gas shield district; and make nozzle become littler, use this welding gun to be installed on the automatic soldering device and can implement welding automatically the weld seam of small space.

2, since the welding gun of the utility model go out fiber tube and escape pipe has a fixed connecting base, conveniently be fixed on the rotary welding device, the weld seam of small space is implemented welding automatically.

3, simple in structure, the low cost of manufacture of the utility model welding gun: economical and practical.

Below in conjunction with drawings and Examples the technical characterictic that the utility model a kind of is used for the welding gun that the gas-shield automatic welding tipping puts is described further.
