Description
Technical field
A kind of Clamp for welding is the utility model is related to, particularly a kind of fixation being used for when the curved surfaces such as cylinder, spherical shell weld
Adjust fixture.
Background technology
Storage tank is widely used in fields such as oil, chemical industry, national defence, traffic, is played an important role in the national economic development.
, it is necessary to be welded to shell plates in storage tank installation process.When welding girth joint, upper and lower two layers of shell plates needs to be grouped.
The group of two neighboring housing is an important factor for influenceing final storage tank installation quality on quality.When housing lifts by self gravitation and
The influence of operation is lifted, housing has certain deformation.In addition, welding process, shell plates is because of the influence of weld seam, shell plates girth
Can contraction distortion.Therefore, be ensure welding quality it is necessary to fixation, adjustment adjacent two layers housing radian, ensure Cylinder assembly quality
With prevent welding after deform.
In the prior art, the most frequently used method of adjustment is to wallboard in group（Two layers of adjacent housing）Outside welding baffle comes
Fixed wallboard, inner side welding angle bar.After spot welding is fixed during group pair, squeezed on the inside of wallboard using wedge inside angle bar, make wallboard slope
Mouth alignment.By that analogy, after one week whole centering of wallboard, group terminates to process., must be clear in groove before baffle plate and angle bar spot welding
Except splashing, foul, grease etc., preparation time length.All baffle plates will finally be carried out with angle bar weld in this method
Cut off and polish.In addition, spot welding a certain degree of can destroy quality of parent material quality, point postwelding need to carry out the fettlers such as polishing that derust
Make, consume artificial amount greatly, tedious process.For the housing that material is stainless steel, need to carry out coloring treatment after polishing, ensure welding
Burnishing part flawless or other defect.For requiring strict material, still need to carry out flaw detection operation, to ensure housing quality.It is right
In steel alloy such as 16Mn, 15CrMo of special substance etc., welding process is also easy to produce crackle, also needs to carry out hot place after the completion of welding
Reason.Therefore, conventional method is artificial, material and other fees expenditure are larger.
CN204818568U discloses a kind of spherical shell plate weld group to fixture, including two locating dowels, locating wedge and connection
Beam, the tie-beam are provided with two through holes, and the both sides of two through holes are respectively provided with two blocks.In use, first by the first positioning
Post and the second locating dowel are respectively welded in two Spherical Tank Shell Plates to be welded, then by two through holes of tie-beam be respectively fitted over two it is fixed
On the post of position, alignment pin is inserted into positioning hole, is fixedly connected with beam.Then locating wedge is inserted between suitable locating dowel and block,
The distance between welding edge is adjusted using the mode of hammer locating wedge.Locating dowel in this method is welded in Spherical Tank Shell Plates
, therefore, after spherical shell welding completion, the welding position of bumping post and Spherical Tank Shell Plates needs to be cut off and polished, and is unfavorable for containment vessel
Sheet material matter.In addition, before housing plate weld, stress concentration is easily caused using the method beaten manually is hammered, it is unfavorable that coverboard is produced
Influence.
In order to reduce auxiliary crator, CN103722341A discloses a kind of cylinder butt joint auxiliary device, including two annulus,
Square steel and threaded rod with silk hole, two annulus are sleeved on group on the outside of cylinder, square steel is welded between two annulus, threaded rod
Cooperated with silk hole and quantity is equal, and silk hole is towards the center of circle.The device is adjusted according to group to the surplus of the unfitness of butt joint of cylinder
Threaded rod is saved, reaches cylinder and docks the effect of minimum unfitness of butt joint, and avoids generation of the group to crator on cylinder, and then is avoided
The processes such as subsequent polishing, repairing, be advantageous to save the artificial and time.But the device be enclosed on group to cylinder outside when, it is necessary to extra
Tool support so that it is parallel with cylinder section or girth joint.Therefore, extra support and levelling step are needed using the device
Suddenly.In addition, the diameter of the device is at least greater than diameter of the group to cylinder, therefore, transports, deposit and be not convenient.
The content of the invention
The problem of existing for prior art, the utility model provide a kind of curved surface and are welded and fixed adjustment fixture, including
