Description

A kind of gas shielded automatic welding machine welding gun

Technical field:

The utility model relates to a kind of annex of welding equipment, particularly a kind of gas shielded automatic welding machine welding gun.

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 one, install and use inconvenience, the nozzle throat area of this type of welding gun generally all is circular in addition, is not easy the weld seam of small space is implemented welding automatically.

The utility model content:

The technical problems to be solved in the utility model: provide a kind of easy to install, be connected and can implement a kind of gas shielded automatic welding machine welding gun of welding automatically with automatic welder(welding machine), to overcome the prior art above shortcomings the weld seam of small space.

The technical scheme that solves the problems of the technologies described above is: a kind of gas shielded automatic welding machine welding gun; comprise the welding gun seat; one flat arc duct is arranged at the top of welding gun seat; it is rifle head nozzle that the front end in arc duct stretches out the gun platform body part; the rear end in arc duct and gun platform rear portion have into that the convex in fiber tube hole is connected; described go out that fiber tube is vertically fixed in the middle part in arc duct and the circular arc duct is divided into about the escape pipe of two back-end closures; the front end that goes out fiber tube is connected with ignition tip; going out the fiber tube tail end is communicated with the fiber tube hole of advancing of convex; advance the interface of the other end for being connected in fiber tube hole with the wire feed conduit; have on the welding gun seat in a while and the arc duct about two escape pipes communicate; or two be not communicated with mutually and respectively with the arc duct in about two air admission holes that escape pipe communicates, air admission hole has the interface that is connected with snorkel.

The further technical scheme that the utility model a kind of is used for the welding gun that the gas-shield automatic welding tipping puts is: there is the closing in towards ignition tip on the rifle head nozzle both sides that the gun platform body is stretched out in described arc duct, and the tapering towards ignition tip is promptly arranged; Described welding gun seat is provided with cable connection point.

Owing to adopted technique scheme, a kind of gas shielded automatic welding machine welding gun of the utility model has following beneficial effect:

1, because the rifle head nozzle of a kind of gas shielded automatic welding machine welding gun of the utility model is pancake; and there is the tapering towards ignition tip at rifle head nozzle place; make the gas of sending towards welding wire; not only help welding fusing point and form good gas shield district; and make nozzle become littler; this welding gun has a fixed connecting base in addition, can be fixed on easily on the automatic soldering device weld seam of small space is implemented welding automatically.

2, since a kind of gas shielded automatic welding machine of the utility model go out fiber tube and escape pipe all is positioned at the welding gun seat and the welding gun seat becomes one, it is simple in structure, compact, low cost of manufacture is not fragile, economical and practical.

Be described further below in conjunction with the technical characterictic of drawings and Examples a kind of gas shielded automatic welding machine welding gun of the utility model.

The specific embodiment:

Embodiment one: a kind of gas shielded automatic welding machine welding gun; comprise welding gun seat 1; one flat arc duct 11 is arranged at the top of welding gun seat; it is rifle head nozzle 12 that the front end in arc duct stretches out the gun platform body part; the rear end in arc duct and gun platform rear portion have into that the convex 7 in fiber tube hole 5 is connected, described go out that fiber tube 2 is vertically fixed in the middle part in arc duct and the circular arc duct is divided into about the escape pipe 3 of two back-end closures ₁With 3 ₂, the front end that goes out fiber tube 2 is connected with ignition tip 10, goes out the fiber tube tail end and is communicated with the fiber tube hole 5 of advancing of convex, and the other end that enters the fiber tube hole has internal thread with the interface that the wire feed conduit is connected, and welding gun seat both sides have two mutual disconnected
