The utility model relates to auxiliary welding equipment field, specifically a kind of steel pipe flange welding special fixture.
Background technology
Welding is the important connected mode of one linked together by two or more hardwares, and at machinery, boats and ships, aviation, chemical industry, the field such as vehicle and pipeline has a wide range of applications.Steel pipe and flange welding are wherein important parts.
Steel pipe, together with flange welding, not only will meet the requirement of pressure and intensity, but also requires attractive in appearance.Once steel pipe flange center line not conllinear (not meeting axiality), steel pipe center line and flange face out of plumb (not meeting perpendicularity), interface is not concordant, not only affect aesthetics, also likely increase the difficulty that follow-up weldment is installed, even likely cause flange connections to leak gas or leakage, thus cause security incident.Under a lot of condition, by the restriction of execution conditions, centerline collineation (meeting axiality), steel pipe center line vertical with flange face (meeting perpendicularity), interface is concordant waits requirement to be difficult to reach.
In actual production operation process, by means of the experience of master worker, first spot welding, then correct with instruments such as angle squares, repeated multiple times, until it is vertical with flange face to meet steel pipe center line, steel pipe flange centerline collineation, interface is concordant.Such operation process, operating efficiency is low, and welding progress is comparatively slow, and the labour intensity of master worker is comparatively large, wastes man-hour, has a strong impact on the progress of welding, quality and aesthetics.
Summary of the invention
It is simple that the purpose of this utility model is to provide a kind of structure, practical and convenient steel pipe flange welding special fixture, mainly solves steel pipe center line and flange face not easily vertical, steel pipe center line and flange center's line not easily conllinear, interface not easily inferior problem of concordant and inefficiency.
The technical scheme in the invention for solving the technical problem is: described a kind of steel pipe flange welding special fixture, this fixture comprises base, support, leading screw, handle, upper locating piece and lower locating piece, upper locating piece and lower locating piece are V-type, its angle is 120 degree, upper locating piece and lower locating piece is positioned opposite and lower locating piece is fixed on base, upper locating piece to comprise on flange locating piece on locating piece and steel pipe, lower locating piece to comprise under flange locating piece under locating piece and steel pipe, on steel pipe, locating piece is designed with and picks up the ears and fit with rack inner wall, on flange, under locating piece and flange, one end of locating piece is all designed with block, in clamping process, under flange one end face and flange, the block of locating piece is fitted, sidepiece and the bottom design of support have reinforcement, prevent the clamping force because applying excessive, cause deformation of timbering, affect the precision of positioning and clamping, base is mainly used in this special fixture being fixed on workbench or other places, in fixture, the length of three rhizoid thick sticks is different, turn handle, leading screw rotates, in control, locating piece moves up and down, thus complete the positioning and clamping treating welded still pipe and flange.
The beneficial effects of the utility model are: the utility model convenient and swiftly can treat welded still pipe flange positioning and clamping, effectively realize steel pipe center line vertical with flange face, steel pipe flange centerline collineation, interface is concordant waits welding requirements, also regulate the gap between steel pipe and flange-interface very easily, improve the quality of welding, saved a large amount of man-hour, improve operating efficiency, alleviate the labour intensity of master worker; This special fixture is simple and compact for structure, uses simple, applied range, easy to carry, economical and practical.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, exemplary embodiment wherein and illustrate and be only used for explaining the utility model, but not as to restriction of the present utility model.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, a kind of steel pipe flange welding special fixture, its structure comprises base 1, support 4, leading screw 10, handle 9, upper locating piece and lower locating piece, upper locating piece and lower locating piece are V-type, its angle is 120 degree, upper locating piece and lower locating piece is positioned opposite and lower locating piece is fixed on base 1, upper locating piece to comprise on flange locating piece 5 on locating piece 8 and steel pipe, lower locating piece to comprise under flange locating piece 2 under locating piece 7 and steel pipe, on steel pipe, locating piece 5 is designed with and picks up the ears and fit with support 4 inwall, on flange, under locating piece 8 and flange, one end of locating piece 7 is all designed with block, in clamping process, under flange 6 one end face and flange, the block of locating piece 7 is fitted, sidepiece and the bottom design of support 4 have reinforcement, prevent the clamping force because applying excessive, support 4 is caused to be out of shape, affect the precision of positioning and clamping, base 1 is mainly used in this special fixture being fixed on workbench or other places, in fixture, the length of three rhizoid thick sticks 10 is different, turn handle 9, leading screw 10 rotates, locating piece in control (on steel pipe on locating piece 5 and flange locating piece 8) moves up and down, thus complete the positioning and clamping treating welded still pipe 3 and flange 6.
When the utility model uses, rotary handle 9, leading screw 10 rotates, by on locating piece on steel pipe 5 and flange, locating piece 8 moves on to correct position, then steel pipe 3 to be put under steel pipe on locating piece 2, flange 6 to be put under flange on locating piece 7, an end face of flange 6 will be fitted with the block of locating piece under flange 7, then gap between steel pipe 3 and flange 6 interface is adjusted, after adjustment, rotary handle 9, leading screw 10 rotates, on steel pipe upper piece 5 and flange, locating piece 8 all moves down, until clamping steel pipe 3 and flange 6, then spot welding; Loosen handle 9, steel pipe 3 and flange 6 are revolved turnback, again adjust clamping, again spot welding, complete a postwelding, off-take point is soldered connect after steel pipe 3 and flange 6, again weld, until complete weld job.
By above-described embodiment, it is vertical with flange face that the use of this special fixture reaches steel pipe center line effectively, steel pipe flange centerline collineation, and interface is concordant waits welding requirements, and economical and practical, efficiency is higher, improves the quality of welding, alleviates the labour intensity of workman.
The foregoing is only embodiment of the present utility model, is not the restriction to the utility model the scope of the claims.Everyly utilize the equivalent structure or equivalent transformation that the utility model is made a summary, description and accompanying drawing content are done, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
