Description
Technical field
The utility model relates to steel-pipe welding technical field, especially a kind of steel-pipe welding positioner.
Background technology
Steel pipe is applied in the building such as pipeline, bridge, and the welding quality of steel pipe is the essential condition used.Welded still pipe also claims welded tube, is after cans, to weld with steel plate or steel band the steel pipe made.Develop and weld the progress with inspection technology rapidly along with quality strip steel rolling production, weldquality improves constantly, and the description of welded still pipe is increasing, and instead of seamless steel pipe in increasing field.Welded still pipe is lower than seamless steel pipe cost, production efficiency is high.
Welded still pipe production technology is simple, and production efficiency is high, and description is many, and equipment investment is few, but common intensity is lower than seamless steel pipe.Welded still pipe is when producing, and misalignment happens occasionally, and its influence factor is a lot.In production practices, often because misalignment is overproof, steel pipe is demoted.Therefore, steel pipe misalignment is avoided to be necessary.Due to the restriction by construction site condition, steel pipe aligning is difficult to alignment, is difficult to ensure Pipe Welding Quality, can not ensure that interface surface is concordant, steel pipe center line alignment lamp, affect construction speed.
Utility model content
The utility model object is to provide a kind of steel-pipe welding positioner, and two steel pipes are kept in the same horizontal line, and the mouth of pipe is alignd, and two steel pipe interface surfaces are concordant, and steel pipe center line aligns, and ensure steel pipe seam quality, accelerating construction progress.
To achieve these goals, the technical solution of the utility model is: a kind of steel-pipe welding positioner, comprise the first positioner and the second positioner, described first positioner comprises two symmetrical clamping plate I connected, arc convex I is had in the middle of clamping plate I, described second positioner comprises two symmetrical clamping plate II connected, arc convex II is had in the middle of clamping plate II, described clamping plate I front end is provided with draw-in groove and opening I, clamping plate I both sides are provided with screw hole I, described clamping plate II front end is provided with fixture block and opening II, and clamping plate II both sides are provided with screw hole II.
Described draw-in groove and fixture block match, and described opening I and opening II matches.
Described clamping plate I both sides have three screw hole I respectively, and two clamping plate I are threaded, and described clamping plate II both sides have three screw hole II respectively, and two clamping plate II are threaded.
The internal diameter of arc convex I is identical with the internal diameter of arc convex II.
With clamping plate I, a steel pipe is fixed, with clamping plate II, another root steel pipe is fixed, the fixture block of clamping plate II front end is positioned in the draw-in groove of clamping plate I front end, opening II is corresponding with opening I together, the junction of two steel pipes is positioned over opening II and opening I, and the mode of workmen's welding by two fastener for connection together.After fixing, take off the first positioner and the second positioner, the position of also not welding is welded together, thus two steel pipes are kept in the same horizontal line, the mouth of pipe is alignd, and two steel pipe interface surfaces are concordant, and steel pipe center line aligns, ensure steel pipe seam quality, accelerating construction progress.

Fig. 2 is the overall structure schematic diagram of clamping plate I;
Fig. 3 is the overall structure schematic diagram of clamping plate II.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, a kind of steel-pipe welding positioner, comprise the first positioner and the second positioner, described first positioner comprises two symmetrical clamping plate I1 connected, arc convex I is had in the middle of clamping plate I1, described second positioner comprises two symmetrical clamping plate II2 connected, arc convex II is had in the middle of clamping plate II2, described clamping plate I1 front end is provided with draw-in groove 3 and opening I4, clamping plate I1 both sides are provided with screw hole I 5, described clamping plate II2 front end is provided with fixture block 6 and opening II7, and clamping plate II2 both sides are provided with screw hole II 8.When needs by two steel-pipe weldings together time, with the first positioner, a steel pipe is fixed, with the second positioner, another root steel pipe is fixed, first positioner and the second positioner can be connected with each other, thus two steel pipes are kept in the same horizontal line, and the mouth of pipe is alignd, two steel pipe interface surfaces are concordant, steel pipe center line aligns, and ensures steel pipe seam quality, accelerating construction progress.
Described draw-in groove 3 matches with fixture block 6, and described opening I4 and opening II7 matches.When connecting the first positioner and the second positioner, fixture block 6 is put into draw-in groove 3, and guarantee that two steel pipes are on same level line, opening I4 aligns with opening II7, the junction of two steel pipes is positioned over opening I4 and opening II7 by workmen, by welding by two fastener for connection together.
Described clamping plate I1 both sides have three screw hole I, 5, two clamping plate I1 to be threaded respectively, and described clamping plate II2 both sides have three screw hole II, 8, two clamping plate II2 to be threaded respectively.The internal diameter of arc convex I is identical with the internal diameter of arc convex II.Ensure that two steel pipes can be on same level line, be convenient to two steel pipe nozzle alignment, steel pipe center line aligns.Be threaded and can ensure that the first positioner and the second positioner fix steel pipe respectively.
During use, with clamping plate I1, a steel pipe is fixed, with clamping plate II2, another root steel pipe is fixed, the fixture block 6 of clamping plate II2 front end is positioned in the draw-in groove 3 of clamping plate I1 front end, opening II7 is corresponding with opening I4 together, the junction of two steel pipes is positioned over opening II7 and opening I4, and the mode of workmen's welding by two fastener for connection together.After fixing, take off the first positioner and the second positioner, the position of also not welding is welded together.
