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 clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Refer to Fig. 1 and Fig. 2, Fig. 1 is the main structure diagram of high energy beam spray gun provided in an embodiment of the present invention, Fig. 2
For the partial enlargement structural representation inside nozzle 11 provided in an embodiment of the present invention.
The embodiment provides a kind of high energy beam spray gun, including linear stepping motor 1 and hafnium filament in communication
Cutting ferrule 2, linear stepping motor 1 are connected with the internal connection pipe sleeve 6 for being provided with breather pipe 7, and breather pipe 7 is similar to air with outside
The equipment of compressor is connected to be passed through compressed air, in addition to the nozzle 11 positioned at connection pipe sleeve 6 one end, nozzle 11 are provided with
Through hole, the inside of nozzle 11, which is provided with, to be used to accommodate detachable electrode and the accommodating chamber connected with breather pipe 7, and detachable electrode includes can
The more than one electrode slice 10 compressed by compressed air and the taper hole clamping set 12 with the elastic connection of electrode slice 10, can preferably be adopted
Both it is easy to processing and installation with each electrode slice 10, two electrode slices 10 up and down, and can enough plays very stable clamping effect,
The electrode slice 10 of other certain numbers is also possible, but the intermediate demand of multiple electrodes piece 10 reserves the logical of the motion of hafnium filament 8
Road.
During the high energy beam spray gun provided using above-described embodiment, compressed air is passed through in breather pipe 7, compressed air, which enters, to be held
Chamber of receiving compresses electrode slice 10, and compressed air promotes taper hole clamping set 12 and the clamping of electrode slice 10, passes through the pressure of electrode slice 10
Clamp force and the clamping force collective effect of taper hole clamping set 12 hold hafnium filament 8 tightly so that the front end of hafnium filament 8 and the front end of electrode slice 10
Concordantly, good starting the arc effect can be played after switching on power.After the front end of hafnium filament 8 consumes, spray gun is stopped not
Be passed through compressed air again, hafnium filament 8 no longer held tightly and can by linear stepping motor 1 by hafnium filament 8 push forward accordingly away from
From this distance can accurately be controlled by external control system.Using said structure design it is possible to prevente effectively from hafnium filament 8 supplements not
11 flimsy phenomenon of motor and nozzle caused by time, and there is good starting the arc effect, while can be compared to existing
The spray gun longer time continuous work (theoretical up to 30 days even longer time), reduce needs frequently manual maintenance
Cost.
In order to optimize above-described embodiment cathetus stepper motor 1 and couple the connection effect of pipe sleeve 6, linear stepping motor 1
It is fixedly connected with connection pipe sleeve 6 by more adapter flanges 3, the outside of more adapter flanges 3 is provided with the tracheae connected with breather pipe 7 and connect
First 4.Linear stepping motor 1 is fixedly connected with connection pipe sleeve 6 by using more adapter flanges 3 so that the connection of the two
It is more stable, and taking and using for spray gun is facilitated, while additionally provide gas-tpe fitting 4 and be connected to the high energy beam spray gun
Link position.The equipment that gas-tpe fitting 4 can provide compressed air with outside connects, and ensure that the compressed air of the high energy beam spray gun
Offer and avoid gas and leak easily.
In an alternative embodiment of the invention, breather pipe 7 is specially circulating line, and its inner ring inner containment has positioned at hafnium filament
Back-moving spring 5 between cutting ferrule 2 and nozzle 11.By setting back-moving spring 5, on the one hand allow hafnium filament 8 preferably along straight
Line advances, and ensure that linear stepping motor 1 can be pushed hafnium filament 8 forward along straight line with more stable, on the other hand can also help
Hafnium filament 8 resets in time, in order to follow-up further push operation.It is noted that back-moving spring 5 is to be sheathed on hafnium filament 8
Outer, the external diameter of hafnium filament 8 and the internal diameter of back-moving spring 5 can be preferably roughly the same, and hafnium filament cutting ferrule 2 and hafnium filament 8 need into
The position for entering nozzle 11 is generally on straight line.
In order to optimize the using effect of nozzle 11 in above-described embodiment, nozzle 11 and the dismountable fixed company of connection pipe sleeve 6
Connect.Although high energy beam spray gun provided by the invention substantially prolongs the service life of electrode and nozzle 11, electrode and spray
Mouth 11 still be able to can not be finally continuing with due to excessive consume, therefore preferred nozzle 11 and connection pipe sleeve 6 are dismountable
It is fixedly connected, can be changed in time when the internal structure of nozzle 11 or nozzle 11 is damaged.Meanwhile dismountable nozzle 11 is also
The filling of hafnium filament 8 is facilitated, when the hafnium filament 8 in high energy beam spray gun runs out of, then can very easily pull down nozzle 11
Reload new hafnium filament 8.
In order to further optimize the using effect of nozzle 11 in above-described embodiment, high energy beam spray gun also includes being installed on receiving
Ring of eddy 9 in chamber.By install ring of eddy 9 can compressed air flow direction change, there is more preferable thrust and punching
Brushing force, and make it that the electric arc of row can also be more high-quality.
In an alternative embodiment of the invention, when electrode slice 10 is not passed through compressed air in breather pipe 7 and accommodating chamber
Inwall snug fit.Preferred electrode piece 10 and the inwall of accommodating chamber are adjacent to, and ensure that electrode slice 10 can be comprehensive when not being compacted
The thrust by compressed air, without because Partial shrinkage air led by the gap leakage of electrode slice 10 and nozzle 11
Cause is difficult to hafnium filament 8 and preferably holds effect tightly.
In order to optimize the connection effect of electrode slice 10 and taper hole clamping set 12 in above-described embodiment, electrode slice 10 and taper hole card
Tight set 12 is connected by retaining spring 13.Using part of the retaining spring 13 as elastic connection, one side accurate positioning and its
Profile is adapted to the column type profile of high energy beam spray gun global design, and another elastic force for facilitating it to provide is moderate and cost is relatively low,
Respective standard part can also be changed after damage in time.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.
