The jockey of a kind of plasma cutting-torch and cable
Technical field
The present invention relates to a kind of plasma cutter, particularly the jockey of a kind of plasma cutting-torch and cable.
Background technology
Plasma cutting be with air by hf electric arc " decompositions " or ionization, become basic atomic particle, thereby the generation plasma utilizes in cutting the formed high temperature of nozzle compression arc, the high speed plasma jet of small-bore to do thermal source and carries out fusion cutting.Cutting torch is the vitals of plasma cutting machine, is also easy wearing detail simultaneously.In prior art, plasma cutting-torch generally is connected with high voltage source by cable.And plasma cutting-torch generally is connected by resistance welded with cable, and welding quality is subject to process conditions and practical operation impact, produce rosin joint, failure welding or use for a long time the cutting torch body of post plasma cutting torch and cable to produce loose contact, make plasma cutting-torch unstable properties, useful life shorten; In addition, plasma cutting-torch is easily worn part, need the frequent parts that plasma cutting-torch disassembled to change loss in actual the use, because cable and plasma cutting-torch weld together, cable often also needs to replace or damage because repeatedly dismantling, and trouble, cable waste, cost raise to cause easily worn part to change comparatively.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide the jockey of a kind of plasma cutting-torch and cable, its stable connection, plasma cutting-torch are changed convenient, long service life.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The jockey of a kind of plasma cutting-torch and cable, it is characterized in that: comprise connector, center pillar, described connector has the first end that removably connects mutually with plasma cutting-torch and the second end that is fixedly installed on cable end piece, described center pillar can be slidably arranged on plasma cutting-torch vertically, and the first end of described connector is set on described center pillar.The second end of described connector is provided with one for the inner chamber that holds cable end piece, and described cable end piece is fixedly installed in the inner chamber of described the second end.
Preferably, also be provided with on described center pillar for the spring leaf with described connector chucking.
Preferably, the second end of described connector also offers draw-in groove, and card is provided with a fixture that prevents the cable axial motion in described draw-in groove.
Geng preferably, described fixture is jump ring.
The present invention adopts above structure, has following advantage:
1, due to the setting that socket-connects of plasma cutting-torch and cable, plasma cutting-torch firmly is connected with cable, and electric conductivity is good, loose contact, long service life can not occur;
2, in the time of need to changing plasma cutting-torch, only need connector is extracted it to be removed from cable from center pillar carry out dismounting and change, replacing is convenient and cable is reusable, saves cable material.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be those skilled in the art will recognize that, protection scope of the present invention is made more explicit defining.
The jockey of a kind of plasma cutting-torch and cable, comprise connector 2, center pillar 14, described connector 2 has the first end 21 that removably connects mutually with plasma cutting-torch 1 and the second end 22 that is fixedly installed on cable 3 ends, described center pillar 14 can be slidably arranged on plasma cutting-torch 1 vertically, and the first end 21 of described connector 2 is set on described center pillar 14.Also be provided with on described center pillar 14 for the spring leaf 15 with described connector 2 chuckings.
The second end 22 of described connector 2 is provided with one for the inner chamber that holds cable end piece, the end of cable 3 stretches in the inner chamber of the second end 22 of connector 2, then the equipment of withholding pipe fitting by buckle machine etc. compresses the second end 22 of connector 2, and it is withheld securely on cable 3 ends.
The second end 22 of described connector 2 also offers draw-in groove 23, and the interior card of described draw-in groove 23 is provided with a jump ring 4 that prevents the cable axial motion.
One end of described center pillar 4 and the first end of connector 2, the other end stretch into electrode 11 places in plasma cutting-torch 1.After the plasma cutting-torch ventilation, air-flow enters the inner chamber of plasma cutting-torch 1 by air inlet pipe 12, air-flow produces propulsive thrust after passing through the spiral vortex ring 13 that is positioned at plasma cutting-torch 1 sidewall, center pillar 4 under the repulsion of air-flow along the axial direction of plasma cutting-torch 1 dorsad electrode 11 slide, make between center pillar 4 and electrode 11 to have had the air gap, can produce plasma arc cutting.
Above-described embodiment for explanation technical conceive of the present invention and characteristics, is only a kind of preferred embodiment, and its purpose is to allow person skilled in the art scholar can understand content of the present invention and implement according to this, can not limit protection scope of the present invention with this.The equivalence that all Spirit Essences according to the present invention are done changes or modifies, within all should being encompassed in protection scope of the present invention.
