Describe the invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of swivel joint apparatus for welding and positioning, as shown in Figures 1 to 4, including set in equipment end 1 equipment end otic placode 2,
And corresponding device end otic placode 2 is arranged on the cutting member end otic placode 4 on cutting member 3, the equipment end otic placode 4 and cutting member end ear
Plate 4 is connected by bolt 5, is provided with and is sleeved on above-mentioned bolt 5, for keeping determining for two otic placode relative positions between two otic placodes
Position set 6；The equipment end 1 is fixed with the location-plate 7 for forming positioning relation with cutting member 3.
It is pointed out that being accurately positioned in order to ensure positioning sleeve, the two sides that positioning sleeve contacts with otic placode are preferably adopted
With finishing processing mode, the two depth of parallelism preferably ensures within 0.05mm.
Specifically, the said equipment end otic placode 2 is uniformly arranged centered on the axis of cutting member 3, per adjacent two equipment ends otic placode 2
Between be equipped with a location-plate 7.
Generally, the said equipment end otic placode 4 is uniformly arranged 4-6 centered on the axis of cutting member 3.
Above-mentioned location-plate 7 is overall to be of an L-shaped structure, and its short side is the connecting portion 8 being connected with equipment end, and long side is to extend cutting
The extension 9 of part side, the positioning boss 10 that certain interval is left with cutting member surface is provided with extension end.In actual behaviour
During work, the positioning boss lower surface of extension end (i.e. free end) can also be bonded with cutting member surface, realize positioning,
Keep equipment end to be fixed with cutting member end relative position, sealing surface reparation completion, again during welding equipment end, ensure that between the two
Relative position.
The above-mentioned middle part of positioning sleeve 6 is along the circumferential direction provided with arcuation groove 11, during cut-space is carried out, arcuation groove
11 are avoided that positioning sleeve is interfered with cutting equipment, ensure that cutting is smoothed out.
Wherein, under state to be cut, plane where each equipment end otic placode is in same plane, each cutting member end
Plane where otic placode is in same plane.It may insure that positioning sleeve is general, also, sealing surface reparation is completed, welding equipment again
During end, cutting member end otic placode and equipment end otic placode are respectively held against using positioning sleeve both sides, keeps the gap of each group of otic placode to consolidate
Fixed, and keep otic placode to be parallel to each other, also just from basic assurance, equipment end is fixed with cutting member end relative position, welds completion
Afterwards, accuracy is high, is not in deviation.
A kind of method that swivel joint welding positioning is carried out using said apparatus is provided below,
Comprise the following steps：
1. draw line of cut along former position while welding；
2. several cutting member ends otic placode 4 is welded and fixed on cutting member 3, each cutting member end otic placode 4 using the axis of cutting member 3 as
Center is uniformly arranged；Equipment end otic placode 2 is welded and fixed in the corresponding cutting member end otic placode 4 of equipment end 1；
3. every group of above-mentioned otic placode is fastened with bolt 5, and be set with positioning sleeve 6, the both ends of positioning sleeve 6 are supported respectively on bolt
Firmly cutting member end otic placode 2 and equipment end otic placode 4；
4. setting a location-plate 7 between per adjacent two equipment ends otic placode, the location-plate 7 is provided with leaves one with cutting member surface
The positioning boss 10 of fixed gap；
5. cut along line of cut section gap；
6. corresponding to each positioning sleeve 6, mark is all made with cutting member end, equipment end and the positioning sleeve sheet, is measured
Positioning convex and the gap on cutting member surface on each location-plate, and record respectively；
7. along cutting wire cutting remainder, equipment end and cutting member end are cut off；Specifically, can be first by line of cut
Some sections are divided into, and makes mark, 5. step is that the region for being first is cut and cut through to mark, 7. step cuts even number
Region, make all connections of cutting seam, equipment end is all cut off with cutting member, demounting bolt, is removed cutting member and is carried out sealing surface dimension
Repair；Why step 5. in directly the cutting of equipment end and cutting member is not separated, be in order to following steps 8. in measure
Go out cutting zone, equipment end and the gap at cutting member end, when being welded again in favor of the later stage, the accurate adjustment of position；
8. sealing surface repair after, according to step 6. in respective markers, equipment end otic placode and cutting member end otic placode are aligned,
By the gap adjusting device end and cutting member end on positioning convex on each location-plate of record and cutting member surface, until with before cut-out
After gap is identical, bolt two otic placodes of fastening for being set with positioning sleeve are re-used, positioning sleeve is maintained two otic placode gaps peace
Row degree；
9. the region of diagonal welding step 7. middle cut-out, after weld bond completely cooling, remove bolt, excision location-plate and each
Otic placode, polishing weld bond.Before equipment end welding is repositioned, weld bond 12 will be processed in equipment end and corresponding cutting member,
Weld bond gap is typically in 2mm.
Wherein, above-mentioned bolt is fastened with torque spanner, Tightening moment 80N*m, the too small then positioning sleeve of Tightening moment can not be tight
Otic placode is pasted, Tightening moment is excessive, then otic placode may be caused to deform.
Wherein, with positioning convex on clearance gauge measurement and positioning plate and cutting member surface gap.Body end is welded in be measured with clearance gauge
Each location-plate and cutting body space, reply original interstice, you can realize axiality before cutting body and cutting after welding before welding
Control.
The invention is simple in construction, reasonable in design, and every group of positioning otic placode is welded in weld seam both sides respectively when cutting body is cut,
After weld bond all cut-out, demounting bolt, cutting body can depart from body, carry out Repair gene, and the dynamic face component after processing is used
Bolt is clamped in body end row welding again, and cutting body resets with the depth of parallelism before cutting and controlled when realizing welding.Equipment after welding
Relative size full recovery to full size, the equipment after maintenance fullys meet factory calibration.
The preferred embodiment of the invention is the foregoing is only, is not intended to limit the invention creation, it is all at this
Within the spirit and principle of innovation and creation, any modification, equivalent substitution and improvements made etc., the invention should be included in
Protection domain within.
