The course of work of the invention is：
During present invention work, workman or machine first install solder in the first adapter to be welded of reservoir 105, followed by high pressure
Air cleaning reservoir 105, then docks the first of reservoir 105 the adapter adapter to be welded with the second of compressor 104 to be welded
Together, then place them in feeding frock elevator delivery feeding frock out, conveyed by streamline.The pressure
Contracting machine 104 is lain in a horizontal plane on the inner support seat 62 of feeding frock, and reservoir 105 is located at the top of compressor 104.When feeding work
When dress is transported to the intersection of the import of flowing water main line 101 and flowing water branch line 102, feeding frock pushes the push-in jacking of mechanism 15
By feeding frock jacking, feeding frock is pushed into push-in branch line 12 to cylinder 152 by the push-in cylinder again, and feeding frock slides into the
During one pushing block 123, the second auxiliary push-in cylinder 122 extends the first pushing block 123, and the first pushing block 123 is located at the rear of feeding frock,
Then the first auxiliary push-in cylinder 121 drives the second auxiliary push-in cylinder 122 to slide, and the first pushing block 123 promotes feeding frock
To in inflated with nitrogen equipment 7.
Then inflated with nitrogen jacking cylinder 761 is by jacking inflated with nitrogen jacking seat 762, so as to by feeding frock, compressor, storage
Liquid device lifting.Meanwhile, inflated with nitrogen lift cylinder 75 falls nitrogen filling component 77 and the circumferentially positioned component 73 of reservoir.Then,
Nitrogen filling cylinder 771 drives filler line 772 to stretch out forward, and filler line 772 is docking together with a conduit of reservoir.Simultaneously
Compressor shaft also drives centralized positioning pipe 722 to be moved along to positioning cylinder 721, and centralized positioning pipe 722 positions compressor
Center.Followed by, the jig arm cylinder 731 drives left jig arm 732 and the clamping of right jig arm 733 so as to correct reservoir and compression
The position of machine.Then, swing arm gas bar 745 drives swing arm 743 to rotate to the rear of compressor, and rear push cylinder 741 drives first to slide
The slid inward of block 742, compressor and reservoir are clamped before and after swing arm and centralized positioning pipe, make its immovable.After compression, then open
Begin to be filled with nitrogen to reservoir（The speed of inflated with nitrogen is 200-1000ML/S）.Nitrogen can prevent metal oxygen in the case where high temperature is welded
Change.Inflated with nitrogen jacking cylinder 761 drives inflated with nitrogen jacking seat 762 to decline, and feeding frock is placed on welding branch line 13, then by
Welding branch line 13 is conveyed to high frequency brazing machine 4.
The middle jacking cylinder 64 of high frequency brazing machine 4 will weld the jacking of feeding frock 6 on branch line 13, while first is drop-down
The cylinder rod of the drop-down cylinder 65 of cylinder 66 and second pulls downward on drag hook, and drag hook 68 is hooked together with coupler body 69, so as to pull down in lower
Support base 62, so that inner support seat 62 departs from compressor 104, the level of compressor 104 is seated in four bullets of outer support seat 61
Property support ball on, compressor 104 can freely be rotated and moved horizontally on outer support base 61, so as to circumferentially positioned compressor 104.
Then the drive installation seat 30 of soldering lift cylinder 46 is moved down, until the welding arc frame of two welding bars 21,22
29 height is concordant with the welding position of first, second adapter to be welded 108,107.
Then, the clamping jaw cylinder 433 of the circumferentially positioned mechanism 43 of reservoir drives left positioning clamping jaw 432, right positioning clamping jaw 431
Opposite rotation is closed up, and left positioning clamping jaw 432, right positioning clamping jaw 431 or so promote the position of correction reservoir 105, make it with pressure
The central axis alignment of contracting machine 104, the first adapter to be welded 108 of reservoir 105 and the second adapter to be welded 107 of compressor 104
Alignment, so as to realize circumferentially positioned reservoir 105.
Then, the jaw cylinder 31 of the circumferentially positioned mechanism 3 of compressor drives left correction arm 32, the right correction slide in opposition of arm 33
And clamping, left correction arm 32, right correction arm 33 correct, position the second adapter to be welded 107 of compressor 104, make itself and reservoir
105 the first adapter to be welded 108 is alignd, so as to realize circumferentially positioned compressor 104, so as to ensure that compressor with reservoir
Adapter to be welded keeps aliging with the center of high frequency brazing coil, it is ensured that welding quality and welding effect, it is to avoid welded pipe occurs
The weld defects such as weldering leakage, burn-through,
Then, drive cylinder drives respective sliding panel slide in opposition, and the front and back end of two welding bars 21,22 closes up, and welds arc
Frame 29 closes up into the high frequency brazing coil 200 of a closure, and the first nitrogen protective housing 28, the second nitrogen protective housing 27 are closed up and enclosed
Box body, two conducting blocks 211 is protected to be connected on copper bar 71 into nitrogen, it is ensured that to be in close contact.Then, high frequency brazing coil 200 is opened
Beginning energization work, heats solder（The weld interval of high frequency brazing machine is 6-8 seconds, and electric current is 60-77A, and frequency is 198-
208KHZ）, nitrogen supply (NS) device also simultaneously toward being filled with nitrogen in nitrogen protecting box body,（Nitrogen supply (NS) device fills to welding position
The speed of nitrogen is 200-1000ML/S）, the welding position for making it be melted in first, second adapter to be welded 108,107, high frequency pricker
When bonding wire circle 200 works, in nitrogen supply (NS) equipment output nitrogen to nitrogen protecting box, nitrogen rises and is protected from oxidation.Weldering
Connect after finishing, all of mechanism is returned to original position, now the adapter to be welded of first, second between compressor 104 and reservoir 105
108th, 107 welding are completed.
After the completion of welding, middle jacking cylinder 64 drops on welding branch line 13 feeding frock, continues by welding branch line
13 are transported to forward release branch line 14, then by aiding in
When feeding frock slides into the second pushing block 143, the second auxiliary releases cylinder 142 and extends the second pushing block 143, the second pushing block
143 drive the second auxiliary release cylinder 142 to slide positioned at the rears of feeding frock, then the first auxiliary push-in cylinder 121, and second
Pushing block 143 releases on flowing water main line feeding frock.
Flowing water main line continues to convey feeding frock, and feeding frock is given the positioning compression device 9, positioning pressure by flowing water main line
Tight device 9 corrects the position of compressor 104 and reservoir 105 and reservoir 105 is pressed on reservoir support 106.It is fixed
After position hold-down gear has compressed reservoir, argon arc welding machine 8 is initially powered up welding again（The welding current 250-270A of argon arc welding machine,
Weld interval 2-3 seconds）, reservoir 105 is welded on reservoir support 106.So far, it is of the invention completed compressor with
All welding sequences of reservoir.Then, the compressor and reservoir in feeding frock are born away by workman, vacant send
Material frock continues to be conveyed to lift after feeding frock by flowing water main line, and feeding frock is dropped to and sent by lift after feeding frock
The material frock line of return, feeding frock is sent back to before feeding frock lift 17 by the feeding frock line of return, is lifted before feeding frock
Feeding frock is lifted to flowing water main line front end by machine 17 again, so as to realize the recycling of feeding frock.
