Piping truss is structural member important in the spaceflight delivering tool of part, carries the load of all engines and body
Lotus, the reliability of piping truss directly determine the reliability of carrier rocket, and piping truss workmanship is the most key is
Erection welding technology, but since truss weld seam concentrates on the design feature of piping, the A LOCAL STRESS-STRAIN in welding process,
Not only directly welded seam area is had an impact, is also easy to produce crackle, it will also be to the accuracy guarantee and dimensionally stable of truss morpheme size
Property has an impact, it is difficult to control, at the same time accessory size is big, complicated, its welding quality is made to propose higher want
It asks.
Utility model content
The utility model for the above-mentioned prior art the problem of, a kind of piping truss welding is provided and heat treatment is fixed
Position device, completes the welding of piping truss high quality, avoids cracking, ensure the dimensional accuracy and dimensionally stable of truss
Property.
The technical solution of the utility model is as follows：
Piping truss welding and heat treatment positioning device, including mounting base, supporting beam, girder, supporting beam fixed link and
Supporting beam is arranged in the top of mounting base fixed link, mounting base, and girder is arranged between mounting base and supporting beam, supporting beam
Supporting beam fixed link is installed respectively between both ends and mounting base, mounting base fixed link is set between mounting base and girder；
Orthogonal X-axis limited block, Y-axis limited block and bottom plate Z axis limited block is arranged in the end of the mounting base.
The mounting base is cruciform shape, and mounting base is equipped with limiting slot.
The limiting slot is symmetrically arranged triangle limiting slot.
There are limit gap, the bottom plate Z between the X-axis limited block, Y-axis limited block and bottom plate Z axis limited block
The lower section of axis limited block is equipped with cushion block.
It is separately installed with supporting beam Z axis limited block above the both ends of the supporting beam.
The both ends of the girder connect bolt by girder and are fixed with mounting base and supporting beam, and the supporting beam is solid
Fixed pole, mounting base fixed link are used and are welded and fixed.
The good effect of the utility model is as follows：
（1）Using the present apparatus carry out piping truss structure welding, can ensure piping truss structure dimensional accuracy and
Dimensional stability.

It is positioned in use, the plate parts in piping truss structure are put on mounting base and supporting beam, places and complete
After assemble each tubular structural member, using bottom plate Z axis limited block, supporting beam Z axis limited block, cushion block, bolt I, bolt II by plate
Class part is fixed, to which the assembly of entire piping truss is completed.
Positioning welding is carried out first, using symmetrical localization method, is managed for every and is only welded one end, after the completion of tack welding, symmetrically
Implement welding, the other side retains telescopic free end, and release stress to be cooled welds the one end that do not weld, welding with after deformation
After the completion, it is Reducing distortion, eliminates stress, welding stress is carried out in 8h and eliminates heat treatment, whole process is in positioning device
Upper progress.After the completion of heat treatment, piping truss is dismantled, completes welding.
It, can be by mounting base, supporting beam in order to adapt to the welding and heat treatment of different size piping truss structures
Different locating slots is processed to adapt to the welding of more different size piping truss mechanisms.
The utility model is described in detail above in association with attached drawing embodiment, those skilled in the art can root
Many variations example is made to the utility model according to above description.Thus, certain details in embodiment should not be constituted to this practicality
Novel restriction, the utility model will be using the ranges that the appended claims define as the scope of protection of the utility model.
