Specific embodiment
As represented in figures 1 through 14, the thin-walled pressure vessel includes upper shell ring 1 and lower shell ring 2 to the present invention, and the upper shell ring is equipped with
Certain hyte 3, the lower shell ring are equipped with a pair of of positioning group 3 and a bushing 4,
The positioning group includes a pair of of expansion tube 31（That is packing）, a pair of of expansion tube 31 is setting up and down and passes through bolt 32
Connection, the center line of a pair of of expansion tube is located along the same line, and the expansion tube has opening 310, in semiclosed looping tube,
The section of the tube body is in long lumbar hole shape（It is rectangle among i.e., both ends are arc）, the tube body is equipped with tracheae 33；Tube body is
Hermetically sealed part by carrying out being filled and deflated by action to tube body, realizes tubular form variation；During inflation, opening is caused to become larger.
A pair of of positioning group 3 is setting up and down, and the bushing 4 is connected in the expansion tube of a pair of of positioning group, and the bushing is in ring
Several welding holes 5 are equipped with upwards, and the welding hole 5 is located between a pair of of positioning group 3, by setting welding hole, it is made to correspond to weldering
Seam convenient for getting out of the way, realizes spot welding action.
The tracheae is equipped with ball valve 34, convenient for control gas action.
310 stagger setting of opening of a pair of of expansion tube 31 in the positioning group, a pair of expansion tube opening intersect, and pass through overlapping
It sets so that positioning group forms complete annular brace area.
The positioning group being located above in a pair of of positioning group is stretched out on the top of the bushing, and the top of the bushing is equipped with one
Outer flange 6 is enclosed, outer flange is set, plays guiding role so that upper shell ring is reliably located in bushing, realizes that upper and lower shell ring is automatic
Group pair.
In a pair of of positioning group on the lower shell ring, L-shaped block 7 is laid with positioned at the bottom of the expansion tube of bottom,
The block is used to support bushing；Block is set, plays secure support bushing.
In a pair of of positioning group on the lower shell ring, lug 8 is respectively equipped on the expansion tube of the top and bottom,
The lug is equipped with connecting hole；Lug is set, convenient for slinging a pair of of positioning group, in lower shell ring location and installation so that a pair of
Spacing is equipped between positioning group, convenient for vacating welding hole site.
The bushing 4 is circular or a pair of of semi-annular shape, convenient for making choice setting according to need of work.
As shown in figs. 7-14, a kind of processing method of thin-walled pressure vessel flexibility full circle welding tooling, comprises the following steps：
1）, upper shell ring location and installation, first a pair of of expansion tube in positioning group 3 is inflated, shell ring is inserted in and adjusts position；
Then gas is discharged；（Expansion pipe diameter becomes smaller, and so since the rigidity of cylinder is much smaller than expansion loop, cylinder becomes round）
2）, lower shell ring location and installation, first the expansion tube in a pair of of positioning group 3 is inflated, is inserted in lower shell ring；Gas is released again
It puts；During release, bushing is put into so that bushing is located between expansion tube and lower shell ring；
3）, the positioning of upper and lower shell ring, upper shell ring is placed in the bushing of lower shell ring, end contact shape between upper and lower shell ring
Into weld seam 10 (as needing the position while welding welded)；
4）, upper and lower shell ring spot welding, a pair of of positioning group on lower shell ring is moved up so that several welding holes correspond to weld seam, lead to
It crosses welding hole and spot welding is carried out to weld seam, form shell ring body；
5）, displacement, a pair of of positioning group is moved down, gets out of the way weld seam（First the expansion tube in a pair of of positioning group is inflated, is made
Expansion tube is obtained to become larger, it is reliable to shift；Gas is discharged again, gets out of the way weld seam, convenient for subsequent operation）；
6）, welding, shell ring body is placed on rolling wheel support 9, weld seam is welded, can automatic welding；
7）, complete.
Expansion tube in the present invention is circular open part, is hermetically sealed part；The ratios such as expansion tube are made by internal pressure
Example becomes larger, and need to ensure that variation carries out in elastic range；After internal pressure discharges, flexible deformation disappears, and expansion tube reduces,
It is close to shell ring simultaneously（I.e. upper and lower shell ring）On.In rigidity, shell ring is much smaller than expansion tube, and the circularity of such shell ring follows this
Frock（That is positioning group）And become round.
