Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
First embodiment:
As Figure 1-3, a kind of weld jig being applicable to long pipe flange, including the pipe box fixture 1 for fixed clamp pipeline to be welded 10, for fixing flange clamp 2 and the mandrel 4 of flange 20 to be welded.
Flange clamp 2 is one-body molded with pipe box fixture 1 or flange clamp 2 is welded on one end of pipe box fixture 1.nullPipe box fixture 1 and flange clamp 2 are cut at diameter for band pipe flange，Pipe box fixture 1 is diametrically to be divided into the first semicanal and the tubular structure of the second semicanal，The diameter of this tubular structure is slightly larger than the diameter of pipeline 10 to be welded，First semicanal and the second semicanal are linked together by ferrum ear 3，Ferrum ear 3 is arranged on the first semicanal and the second semicanal joint，2 through holes it are equipped with on ferrum ear 3，It is bolted through hole the first semicanal and the second semicanal to be fixed together，Flange clamp 2 is the flange arrangement of diametrically dimidiation，Flange clamp 2 is provided with the flange positioner for fixing flange 20 to be welded，Flange positioner is several installing holes or pilot pin arranged along flange clamp 2 even circumferential，If installing hole，It is bolted installing hole to be linked together with flange clamp 2 by flange 20 to be welded，If pilot pin，Directly pilot pin penetrates the installing hole on flange 20 to be welded.
nullAfter flange clamp 2 and pipe box fixture 1 are set on pipeline 10 to be welded，It is bolted ferrum ear 3 to be gripped by pipeline 10 to be welded，It is internal that mandrel 4 is set in pipeline 10 to be welded，One end of mandrel 4 is connected with rotary shifter，The other end is fixed together by one end of locating shim 5 and bolt 6 with pipeline 10 to be welded，The other end of pipeline 10 to be welded is supported in the frame of rotary shifter，The length of mandrel 4 can regulate，To adapt to the pipeline of different length，The diameter of locating shim 5 is more than the internal diameter of pipeline 10 to be welded and less than its external diameter，The end of mandrel 4 is provided with screwed hole，By bolt 6, locating shim 5 is compressed the end of pipeline 10 to be welded，Pipeline 10 to be welded can rotate with mandrel 4，The pipe box fixture 1 that pipeline 10 to be welded passes through clamping rotates together with driving flange clamp 2 to be welded with flange clamp 2，And keep relative position to fix.
