A kind of metal welding of workpiece surface and surface modification technology.Plasma arc is the machinery by torch neck
Compression and the high-performance electric arc of electromagnetic compression, there is the characteristics of current density is high, and energy is high, therefore have
The characteristics of speed of welding is fast, and welding material is wide, it can also be carried out very for the superalloy powder of some infusibilities
Good welding, has a wide range of applications in welding field.
The powder feeding structure of existing plasma arc powder surfacing rifle is mostly straight tube powder feeding, and powder feeding pipe is through welding gun
Upper lower gun body, powder feeding flexible pipe dock with powder feeding pipe on rifle top, cause powder feeding pipe to occupy space larger, make
Larger limitation suffered by use.Also a kind of powder feeding structure is that single powder feeding pipe plug flat enters lower gun body, with lower rifle
The powder feeding circuit UNICOM in internal portion, because powder feeding channel design is complicated inside gun body, easily there is showing for stifled powder
As.
Existing plasma arc powder surfacing rifle is mostly packaging simultaneously, and the volume of rifle is relatively thick, long
Easily occurs the shortcomings that electrical insulation properties decline, water, hermetic seal effect decline after time use, to understand
Certainly these problems, therefore, it is proposed that a kind of novel plasma pile of grounds welding gun.
The content of the invention

The inside for the lower gun body stated is provided with tungsten electrode and the poly- middle ring of tungsten electrode, and the inside of described lower gun body is provided with side by side
Powder feeding tube passage and protection gas passage, described powder feeding tube passage interpolation have powder feeding pipe, described powder feeding pipe
Lower gun body insertion torch neck is stretched out in lower end, and the side of the lower gun body is provided with ion tracheae and arc maintenance wiring
Pipe, the torch neck inside is provided with Water-cooling circulating passage and powder feeding hole, and lock is provided with the outside of torch neck
Tight ring.
Preferably, the powder feeding pipe side is provided with protection tracheae, and the protection tracheae is set respectively with powder feeding pipe
There are two, be distributed for axial symmetry.
Preferably, the top of the torch neck is provided with positioning step, and the positioning step stretches into for circle
Lower gun body.
Preferably, the lower gun body bottom is provided with gas shield cover.
Compared with prior art, the beneficial effects of the invention are as follows：The novel plasma pile of grounds welding gun, is adopted
With special die casting structure structure, gun body is reduced, adds electrical insulation properties and sealing property, together
When add positioning step, while nozzle axial direction concentricity is ensured, add the sealing of ion-gas,
Overall structure is simple, compact, is advantageous to promote the use of.
Brief description of the drawings
Fig. 1 is a kind of novel plasma pile of grounds welding gun structural representation of the present invention.
Fig. 2 is a kind of novel plasma pile of grounds welding gun side structure schematic diagram of the present invention.
In figure：1st, water circulation channel 2, torch neck 3, lower gun body 4, protection tracheae 5, give
The poly- middle ring 9 of tube cell 6, die cast 7, tungsten electrode 8, tungsten electrode, gas shield cover 10, locking
Ring 11, ion tracheae 12, arc maintenance wire barrel, 13 torch bodies, 14 positioning steps.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present invention, and
The embodiment being not all of.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing
Go out under the premise of creative work the every other embodiment obtained, belong to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention provides a kind of technical scheme：A kind of novel plasma pile of grounds welding gun,
Including torch body 13, the outside of the torch body 13 is provided with die cast 6, and bottom is provided with lower gun body
3, the inside of described lower gun body 3 is provided with tungsten electrode 7 and the poly- middle ring 8 of tungsten electrode, described lower gun body 3 it is interior
Portion is provided with powder feeding tube passage arranged side by side and protection gas passage, and described powder feeding tube passage interpolation has powder feeding pipe 5,
The described lower end of powder feeding pipe 5 stretches out lower gun body 3 and inserts torch neck 2, and the side of the lower gun body 3 is provided with
Ion tracheae 11 and arc maintenance wire barrel 12, the inside of torch neck 2 are provided with Water-cooling circulating passage 1 and sent
Powder hole, and the outside of torch neck 2 is provided with retaining ring 10.
