Description
Technical field
The utility model relates to a kind of supplemental support frock for cylindrical shell butt welding.
Background technology
The butt welding of two cylindrical shells is a kind of more common welding processing means, in some field, the morpheme such as axiality, cylindricity parameter to postwelding two cylindrical shells has very high requirement, therefore, in welding process, maximum difficult point is how to control the circularity of unfitness of butt joint between two cylindrical shells, cylindrical shell butt end and how reduces impact that welding slag, welding deformation bring etc.And traditional butt weld technologies for steel, the mode that generally adopts side weld edge fit to proofread and correct, this just has very high requirement to workman's weld horizontal, and welding efficiency is low simultaneously, has increased workman's labour intensity.
Utility model content
The purpose of this utility model is to provide a kind of two cylindrical shell axialities of butt welding, supplemental support frock of cylindricity of guaranteeing, the low problem of butt weld technologies for steel welding efficiency of proofreading and correct in order to solve existing employing side weld edge fit.
The utility model adopts following technical scheme: a kind of supplemental support frock for cylindrical shell butt welding, comprise by two sections of above arc packings and enclose and form, radially distending is to hold out against the annular brace circle of inwall at two cylindrical shell docking location places simultaneously, the inner side of bracing ring is provided with bracing ring is applied to the radially force application apparatus of jacking force, force application apparatus comprises the Connection Block that is positioned at bracing ring center position, Connection Block is provided with along Connection Block circumferentially uniform, what expandable moved determines push rod, each end of determining push rod is respectively equipped with and circumferentially extends along Connection Block, for strutting the arc fagging of bracing ring.
On the outer peripheral face of described bracing ring, there is annular groove indent, that circumferentially extend along it, the weld seam that this annular groove produces in order to dodge two cylindrical shell butt welding.
The joint of adjacent two described packings is docking together by the adaptive convex-concave portion coordinating of pegging graft of coincideing respectively.
Described Connection Block is provided with along circumferentially uniform working cylinder of Connection Block, describedly determines the piston rod that push rod is working cylinder.
Described each working cylinder is arranged on Connection Block by the mount pad setting firmly on Connection Block, and each mount pad has the locating hole coordinating with the cylinder body location grafting of corresponding working cylinder.
Described packing is copper packing.
Adopt the supplemental support frock of said structure, because bracing ring is annular, therein under the force application apparatus effect of side, each arc fagging to bracing ring apply from inside to outside, along its circumferential equally distributed radial thrust, make bracing ring can radially prop up expansion, and hold out against the inner side at two cylindrical shell docking location places, play like this effect that two cylindrical shells are aligned, can meet the Geometrical Tolerance Principle such as axiality, cylindricity of two cylindrical shells, also just need in the time welding, not proofread and correct, improve welding efficiency, reduced workman's labour intensity.

The specific embodiment
The embodiment of the supplemental support frock for cylindrical shell butt welding of the present utility model: as shown in Fig. 1-7, comprise annular brace circle 3 and force application apparatus, bracing ring 3 is enclosed and is formed by the first packing 6 and the second packing 7, two packings are arc packing, force application apparatus is arranged on the inner side of bracing ring 3, its effect is exactly to provide uniformly radially jacking force for bracing ring 3, under the effect of force application apparatus, when bracing ring 3 is subject to from inside to outside, during along its circumferential equally distributed radially jacking force, just can radial dilatation also be pressed in two cylindrical shell docking location places in identical top, play like this effect that two cylindrical shells are aligned, can meet the axiality of two cylindrical shells, the Geometrical Tolerance Principle such as cylindricity.Described force application apparatus mainly comprises Connection Block 2, hydraulic cylinder 5 and arc fagging 4, wherein Connection Block 2 is arranged on bracing ring 3 center positions, it is shaped as square cartridge structure, on four side wall surfaces of Connection Block 2, be installed with a mount pad 1 by screw respectively, mount pad 1 has the locating hole 11 inserting for the cylinder body location of hydraulic cylinder, hydraulic cylinder 5 has four, and positioning and plug-in mounting is on four mount pads 1 respectively for four hydraulic cylinders 5, and each hydraulic cylinder 5 is along the periphery that is circumferentially evenly distributed on Connection Block 2 of Connection Block; Fagging 4 has four, and the inner concave centre position place of fagging 4 has and the piston rod of hydraulic cylinder 5 jack coordinating of pegging graft, and such four faggings 4 are inserted into respectively the piston-rod end of four hydraulic cylinders 5.
When application, whole frock is positioned at cylindrical shell inner side, guarantee in Connection Block 2 and the coaxial situation of cylindrical shell, utilize the piston rod of four hydraulic cylinders 5 to stretch out simultaneously, drive four faggings 4 towards moving towards bracing ring 3 simultaneously, thereby bracing ring 3 is radially propped up until bracing ring 3 holds out against the inwall of two cylindrical shells simultaneously, just can be carried out afterwards weld job, the piston rod of hydraulic cylinder 5 is to determine push rod along Connection Block 2 is radially telescopic.
As further optimization, on the outer peripheral face of bracing ring 3, there is annular groove 31 indent, that circumferentially extend along it, the docking location of annular groove 31 corresponding two cylindrical shells, can dodge like this weld seam that two cylindrical shell butt welding produce, avoid bracing ring and cylindrical shell to bond together, and the width of groove 31 is to design for the width requirement of weld seam.
As further optimization, two end positions of the first packing 6 have respectively a breach that runs through its outside, have formed respectively like this first protuberance 62 and the first recess 61 arranged from inside to outside at the both ends of the first packing; Two end positions of the second packing 7 have respectively a breach that runs through its inner side, the second recess 72 and the second protuberance 71 arranged have from inside to outside been formed respectively like this in the end of the second packing, two packings rely on corresponding grafting protruding, recess to coordinate and are docking together, this Split type structure of bracing ring 3, is conducive to the dismounting of postwelding.
As further optimization, first, second packing is red copper packing, for the cylindrical shell that adopts ferrous material, because packing is different from the material of cylindrical shell, is also just not easy the two to weld together.
When above-described embodiment is specifically installed, first two cylindrical shells wanting butt welding are fixed on rotatable positioning clamping fixture, then above-mentioned frock is put into the inner side at two cylindrical shell docking location places and fixes, start four hydraulic cylinders 5 simultaneously, four faggings 4 are moved towards bracing ring 3, four faggings 4 apply jacking force to bracing ring 3 simultaneously, until can start welding after each packing distending the common internal face that compresses two cylindrical shells, and as requested wanting the cylindrical shell weldering of butt welding till full one week.
In above-described embodiment, hydraulic cylinder is as the working cylinder of force application apparatus, and in other embodiments, working cylinder can be also cylinder or some push rod, certainly, in other embodiments, also working cylinder can be changed into screw-nut body, determines the leading screw that push rod is this mechanism.
