Description
Technical field
The invention belongs to soldering tech field, and in particular to the fixture of control fuel manifold pricker post welding distortion.
Background technology
Fuel manifold is the important component of engine, and the fuel oil of engine need of work will be conveyed by manifold,
So part carries out it is particularly important that components welding technique.24 spout single-pieces need to be attached by part with oil pipe by soldering,
The technical problems such as parts warranties fuel flow, the fuel distribution uniformity and atomization quality after soldering.The component weldering of fuel manifold
Connect and share 96 weld seams；There is the control requirement of position degree and nozzle plane degree equidimension after welding, size is very in brazing process
It is difficult to guarantee.
Structural analysis is carried out for part, total pipe part is by the spout 24 with gas hood, major and minor each 24 of oil-way pipe
It is composed by vacuum brazing, technological requirement part ensures 24 relatively independent band gas hood spout ends after carrying out vacuum brazing
Fit Plane degree≤the 0.3mm in face.
Vacuum brazing is natively completed under the condition of high temperature (1050 DEG C~1065 DEG C), and material is deposited in itself at high operating temperatures
In thermal expansion, effective positioning of part can not be carried out at high temperature, so the flatness of part can not almost ensure after welding.
To sum up, the flatness for welding rear jet end face cannot meet design requirement, therefore, it is necessary to design a kind of fixture, both
Execute-in-place and size Control can be facilitated to can guarantee that size of the weldquality of part, component etc. again.
The content of the invention
The technical problem to be solved in the present invention is：It is proposed a kind of fuel manifold soldering fixture, overcome soldering rear jet end
The irregular tilt problem in face, so as to reach the design requirement of flatness≤0.3mm, reduces subsequent correction difficulty, shortens correction work
When, improve production efficiency.
Technical scheme is as follows：
A kind of fuel manifold soldering fixture, including circular ring shape matrix, are equidistantly provided with circular ring shape matrix excircle
Observation panel；
Multigroup compressing unit being spacedly distributed is provided with circular ring shape matrix upper surface, the compressing unit includes and spiral shell
The briquetting of male screw connection, and the fulcrum bearing below briquetting；
The stud is perpendicular to circular ring shape matrix upper surface；
Locking nut is provided with above the briquetting and in stud end.
The length of the briquetting is more than or equal to stud to the distance of fulcrum bearing.
The briquetting is strip, and bottom surface is a plane, and one end of briquetting is provided with connecting screw hole, the area of section of briquetting by
Screw hole end gradually increases to free end.
The fulcrum bearing is annular element, and graphite bushing is provided with inner ring.
One end of the invention by supporting seat supports spout, and briquetting compresses the other end face of spout, utilizes screw thread essence
The height of multiple briquetting seal faces is really controlled, so as to control the flatness of multiple spout welding rear end faces, vents face is solved and inclines
The problem of oblique, reduce subsequent correction difficulty, reduces correction man-hour, improves efficiency.Meanwhile briquetting uses variable cross-section form, by spiral shell
Nose end gradually increases to free end area, i.e., smaller with the briquetting section at Stud connection end, and away from stud end section area compared with
Greatly, the purpose is to increase the dead weight of that section of briquetting contacted with vents face so that even if stud bending at high temperature,
Briquetting free end (that section contacted with vents face) remains to keep pushing down vents face substantially, avoids vents face from departing from
Over-tilting (during the weld contraction being connected with oil pipe, vents face can rotate inclination) occurs for the seal face of briquetting, another
Aspect, adds graphite bushing in fulcrum bearing, avoid spout weld after due to metallic element evaporation under high vacuum and and fulcrum bearing
The situation of bonding occurs, and avoids and scraps problem caused by it cannot normally take out spout.

Embodiment
Technical scheme is further described below in conjunction with the accompanying drawings, but claimed scope is not limited to institute
State.
As shown in Figure 3, it is necessary to by 24 spouts 9 with gas hood and major and minor 8 soldering connection of oil-way pipe, and after ensuring soldering
Flatness≤0.3mm of 24 spouts 9.
As depicted in figs. 1 and 2, fuel manifold soldering fixture, including circular ring shape matrix 1, on 1 excircle of circular ring shape matrix
24 observation panels 2 (i.e. by after excircle decile, in Along ent location arrangements observation panel 2) are equidistantly provided with, observation panel 2 is one
Run through the notch of matrix 1 along 1 axis direction of matrix, be provided with fulcrum bearing 3 on 1 upper surface of matrix between notch, fulcrum bearing 3 is used
In one end of support spout 9, fulcrum bearing 3 on the line in 1 center of circle of matrix and on 1 upper surface of matrix with setting one perpendicular to base
The stud 6 of 1 upper surface of body, strip briquetting 5 is threaded with stud 6, the section of briquetting 5 is from nearly 6 end of stud to away from spiral shell
