Description
Technical field
It the utility model is related to pressure vessel manufacturing field, more particularly to a kind of support of large diameter thin wall grooves with seal heads inwall
Frock.
Background technology
At present, end socket is part important in pressure vessel, is generally required after the completion of envelope compacting and its end groove is carried out
Processing.For large diameter thin wall end socket, because wall thickness is smaller, port stiffness is poor after the completion of end socket compacting, in transport process
Processing request can not be reached by being easy to occur the port i.e. port ovality of deformation, even if ovality controls within the specific limits, be added
Man-hour also results in deformation due to cutting force.
Conventional method is typically by including end socket inwall installs cross or rice font support frame additional and is welded to connect
The mode of wall prevents from deforming, and still, this method does not have preferable supporting role for large diameter thin wall end socket yet, and control is difficult
Degree is big and also not high to the control accuracy of ovality, also needs to use a large amount of tubing during use, assembles complex and high cost.
Utility model content
Technical problem to be solved in the utility model be to provide it is a kind of it is easily controllable, control accuracy is high and simple in construction
Large diameter thin wall grooves with seal heads inwall supporting tool.
To solve the above problems, a kind of large diameter thin wall grooves with seal heads inwall supporting tool described in the utility model, bag
Include：Circular support mechanism positioned at center, be laid in the circular support mechanism edge slideway and can on the slideway from
By the expansion link slided, fixed between the two by fixed component；End of the expansion link away from the circular support mechanism
Provided with the internal thread passage being used cooperatively with jackscrew external screw thread, in use, the jackscrew is screwed in into the internal thread passage, make it
Head is stretched out to support grooves with seal heads inwall.
Preferably, the circular support mechanism can include several supports of both interior annular, outer support ring and connection
Bar, the uniform slideway in the outer support ring.
Preferably, the circular support mechanism can also be plectane.
Preferably, the fixed component can be steady pin, be laid with several pin-and-holes, institute on the expansion link vertically
State slideway and be provided with a pin-and-hole, realized fix through respective pin-and-hole by the steady pin between the two.
Preferably, the slideway can be groove-like slideway, and the expansion link slides in the groove of the slideway.
The utility model has advantages below compared with prior art：
1st, the slideway and expansion link being used in conjunction with each other are provided with the utility model, expansion link can be on slideway slidably
And the position being adapted with end socket internal diameter is fixed on, meanwhile, telescopic rod end is provided with the jackscrew of support grooves with seal heads inwall, is pushing up
, can be by turn jackscrew come the accurate ovality for controlling groove while silk support.It can be seen that the utility model is simple in construction, behaviour
Facilitate, easily controllable and control accuracy is high, effectively overcome large diameter thin wall end socket port poor rigidity, it is yielding the defects of,
Improve end socket machining accuracy and then improve product quality.
2nd, the support for adjusting whole supporting tool in the utility model by effective bearing length of adjustable telescopic rod is straight
Footpath, therefore the utility model can adapt to the end socket of different diameter specifications, it is versatile.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of expansion link 5 and jackscrew 6 in Fig. 1.
In figure：1-interior annular, 2-outer support ring, 3-support bar, 4-slideway, 5-expansion link, 6-jackscrew, Gu 7-
Rationed marketing, 8-end socket.
Embodiment
As shown in Figure 1 and 2, a kind of large diameter thin wall grooves with seal heads inwall supporting tool, the supporting tool include：In being located at
The circular support mechanism of the heart, it is laid in eight slideways 4 at the circular support mechanism edge and is used in combination with slideway 4
Expansion link 5, slideway direction is consistent with circular support mechanism radial direction, and expansion link 5 can be on slideway 4 along the free skating of slideway direction
It is dynamic, it can be fixed between the two by fixed component when needing；In end of the expansion link 5 away from circular support mechanism
It is used cooperatively provided with the external screw thread on internal thread passage, with jackscrew 6, in use, jackscrew 6 is screwed in into internal thread passage, makes its head
Portion is stretched out from internal thread passage to support the groove inwall of end socket 8.
Wherein, circular support mechanism includes several support bars 3 of both interior annular 1, outer support ring 2 and connection, slideway 4
It is located in outer support ring 2.Certainly, slideway 4 is as set to provide place and with one from the effect of circular support mechanism
Fixed enabling capabilities, it can also be plectane, and slideway 4 is located at plectane edge.
Further, slideway 4 is groove-like slideway, and expansion link 5 slides in the groove of slideway 4；Slideway 4 and expansion link 5
Between fixed by steady pin 7, specifically, be laid with several pin-and-holes on expansion link 5 vertically, slideway 4 is provided with a pin
Hole, between the two by steady pin 7 through respective pin-and-hole realize fix, it is, of course, understood that in outer support ring 2 with cunning
Also there is pin-and-hole the pin-and-hole corresponding position of road 4.It is only for example this area skill with the fit system of sliding way 4 and expansion link 5
Art personnel can also be implemented using other expansion fit modes.
During making, the several support bars and slideway 4 of both interior annular 1, outer support ring 2, connection are welded to form fixed part
Point, expansion link 5 is threadedly coupled into movable part with jackscrew 6, and the external diameter of expansion link 5 is smaller 1-2mm than the internal diameter of slideway 4, so as to expansion link 5
It can be moved freely in slideway 4.In actual applications, the quantity of slideway 4 set in circular support mechanism can be by art technology
Personnel carry out being adapted setting according to the actual requirements, meanwhile, or the expansion link 5 of the configuration different length of slideway 4, to adapt to more
The end socket 8 of major diameter scope.
In use, be effective bearing length according to the length of the size adjustable telescopic rod 5 of end socket 8 stretching circular support mechanism,
So that the place diameter of a circle of jackscrew 6 is more smaller than the port inner diameter of end socket 8 on expansion link 5, the position of expansion link 5 is fixed with steady pin 7；Will
Supporting tool is put to the port of end socket 8, its head is stretched out internal thread passage to support end socket 8 using spanner turn jackscrew 6
Groove inwall, while measure turn jackscrew 6 after the actual ovality in the port of end socket 8 and adjust the ovality of end socket 8 and reach processing request.
During retaining wall on slope, jackscrew 6 plays effective supporting role to the port of end socket 8, and it is firm largely to add the port of end socket 8
Property, prevent the deformation in process.
