Description

Attemperator pipeline welding positioning tool

Technical field

The utility model relates to solder technology, particularly relates to the technology of a kind of attemperator pipeline welding positioning tool.

Background technology

Attemperator pipeline is primarily of sparge pipe, and 2 root beads are connected on the circular arc bend pipe on sparge pipe, and the pipe fitting that 6 root beads are connected on bend pipe is formed.Require during welding that 2 bend pipes are on same circular arc week, existing welding method first sparge pipe and 2 circular arc bend pipes is put to take setting-out on jig, weld one by one again, and then all the other 6 pipe fittings are welded on 2 bend pipes one by one, the pendulum of this welding method to sparge pipe and bend pipe is taken calibration and is required very high, easily there is position deviation in platform setting-out, and be also easily subjected to displacement between pipe fitting in welding process, after easily causing welding, 2 bend pipes are not on same circular arc week, and its weld job qualification rate is relatively low.

Utility model content

For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of attemperator pipeline welding positioning tool that can improve weld job qualification rate.

In order to solve the problems of the technologies described above, a kind of attemperator pipeline welding positioning tool provided by the utility model, it is characterized in that: comprise locating rack, described locating rack offers six strip locating holes be parallel to each other, each locating hole is laid along a circumference interval, is all equipped with the locating piece that an energy slides along locating hole in each locating hole;

Described locating piece is the stairstepping cylinder of undergauge step by step from the bottom to top, and each locating piece is all configured with an alignment pin, and the axle center of locating piece offers the cylindrical body pin bore that can pass for the pin rod of alignment pin, and the aperture of this pin-and-hole is less than the pin cap external diameter of alignment pin.

The attemperator pipeline welding positioning tool that the utility model provides, utilize manufactured pipe connector on bend pipe, two bend pipes are located by the cooperation of locating rack, locating piece and alignment pin, make two bend pipes can be on same circumference, and also can not be subjected to displacement between pipe fitting in welding process, the weld job qualification rate of attemperator pipeline can be improved.

Detailed description of the invention

Illustrate below in conjunction with accompanying drawing and be described in further detail embodiment of the present utility model, but the present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar change thereof, all should list protection domain of the present utility model in.

As Figure 1-Figure 2, a kind of attemperator pipeline welding positioning tool that the utility model embodiment provides, it is characterized in that: comprise locating rack 1, described locating rack 1 offers six strip locating holes 2 be parallel to each other, each locating hole 2 is laid along a circumference interval, is all equipped with the locating piece 3 that an energy slides along locating hole in each locating hole 2;

Described locating piece 3 is stairstepping cylinders of undergauge step by step from the bottom to top, each locating piece 3 is all configured with an alignment pin 4, the axle center of locating piece 3 offers the cylindrical body pin bore 31 that can pass for the pin rod of alignment pin, and the aperture of this pin-and-hole 31 is less than the pin cap external diameter of alignment pin.

The utility model embodiment is applicable to attemperator pipeline weld job, and its using method is as follows:

As Figure 3-Figure 4, attemperator pipeline comprises sparge pipe 8, and 2 circular arc bend pipes 9 be welded on sparge pipe 8,6 pipe fittings be welded on two bend pipes 9, sparge pipe 8 wherein offers two bent pipe interface, 2 all single-ended sealings of bend pipe 9, and 3 pipe connectors are respectively offered on 2 bend pipes 9;

First according to finished article design size before welding, pin-and-hole locating piece 3 in six locating holes on locating rack 1 being adjusted to each locating piece axle center is on same circumference, again the non-sealing end of 2 bend pipes 9 is inserted sparge pipe from two bent pipe interface of sparge pipe 8 respectively, and 6 pipe connectors on 2 bend pipes 9 are aimed at one by one with the axle center pin-and-hole of six locating pieces 3, with alignment pin, 2 bend pipes 9 and each locating piece 3 are sold fixed again, thus by the locking position of 2 bend pipes 9 with sparge pipe 8, 6 pipe connectors now on 2 bend pipes are on same circumference, now can implement to weld with the joint portion of 2 bend pipes to sparge pipe, again each alignment pin is extracted after welding, and take off locating rack, again other pipe fitting is welded to one by one on 2 bend pipes, attemperator pipeline weld job can be completed, thus obtain the attemperator pipeline finished product shown in Fig. 4, by the location of positioning tool, 2 bend pipes can be made to be on same circumference, the attemperator pipeline qualification rate of thus welding out can significantly improve, and stairstepping locating piece can adapt to the pipe connector of different bore on various bend pipe.
