Description
Technical field
The present invention relates to assembling test technical field, more particularly to during a kind of whole welding type hydraulic actuator assembling test
Fixture before weldering used in Fluid Resistance Test.
Background technology
Hydraulic actuator is one of significant components in nozzle of aircraft engine tail, its function be stretched by piston, contract come
Control the expansion of nozzle, receive, adjust the thrust of engine to a certain extent.Such as figure one is certain h type engine h hydraulic actuation barrel structure
Schematic diagram, design document requirement carries out Fluid Resistance Test with fuel oil RP-3 to the E chambers runner of pressurized strut, as outlet pressure PGo out=
(0.883~1.08) MPa, pressure difference is Δ P=(0.206~0.265) MPa, when piston is in stretching state, pressurized strut E chamber streams
Amount is not less than 500ml/s.
At present, the Fluid Resistance Test in industry for whole welding type pressurized strut carries out after welding fabrication, i.e.,
Component without Fluid Resistance Test, but uses this Technological Experiment Scheme before welding fabrication, the E chamber flows after components welding
It is less than 500ml/s always, is unsatisfactory for design document requirement.Since component belongs to whole welding type structure, stream of the postwelding to component
Amount performance can not be adjusted, therefore the concession processing that can only go through the formalities of the overproof component of flow uses, and overproof more scraps.It is comprehensive
On, existing assembling test scheme cannot meet whole welding type pressurized strut Fluid Resistance Test requirement.
The content of the invention
The technical problem to be solved in the present invention is：Fluid is carried out before a kind of weldering for whole welding type hydraulic actuator is provided
The fixture of resistance test, is conveniently adjusted each position physical dimension of start barrel part, with ensure the flow before components welding be in by
Control state, so as to ensure the flow performance after components welding.
To solve the above problems, a kind of fixture of Fluid Resistance Test before whole welding type hydraulic actuator weldering need to be provided,
To implement E chamber Fluid Resistance Tests, by finely tuning finishing part region of interest physical dimension (such as double oil-way pipes during experiment
The size of the crescent of holder assembly, throttling nozzle aperture, bushing, piston etc.), make the physical dimension matching of the part of influence flow, really
Flow is not less than 530ml/s before protecting welding, and then ensures that the flow of part postwelding meets the requirement not less than 500ml/s.
Technical scheme is as follows：
Fluid Resistance Test fixture before a kind of weldering of whole welding type hydraulic actuator, including be coaxially set and respectively with a left side
The left bolt and right bolt that fixed seat and right fixed seat are threadedly coupled, positioning seat is provided between left fixed seat and right fixed seat,
Positioning seat upper end is connected with fuel inlet fitting, and through hole is provided with positioning seat.
The left fixed seat and right fixed seat are a pair of parallel and with screw hole tablet.
The positioning seat is one piece of L shaped plate parallel with left fixed seat and right fixed seat.
The right fixed seat can be moved along right bolt axis direction.
The left fixed seat and right fixed seat are connected with tailstock system, and tailstock system includes a tabular upper surface, upper end
There is a pair of parallel sliding slot in right bolt axis direction on face, have a sliding block above sliding slot, the side of sliding block is provided with a notch.
The through hole is square hole.
The realization principle of the present invention is as follows：
1) design first and make Fluid Resistance Test fixture before a set of weldering, welding flow test fixture is by tailstock system
(i.e. clamp body), positioning seat, left and right fixed seat, left and right bolt, fuel inlet fitting composition；
2) by the fixture of design, set at piston rod place to be welded with double oil circuit tube sockets, piston cavity and conduit close
Sealing, applies opposite active force by left and right bolt, completes parts fixation positioning, while by opposite active force, make close
Sealing deformation reaches sealing function, it is ensured that passage forms and external leakage does not occur；
With existing Fluid Resistance Test Technical comparing, its advantage is mainly reflected in：
1) Fluid Resistance Test is carried out to component before welding using the fixture, by finely tuning finishing part during experiment
Region of interest physical dimension (replaces different component combination forms), makes the physical dimension matching of the part of influence flow, really
Flow is not less than 530ml/s before protecting welding, and then ensures that the flow of part postwelding meets the requirement not less than 500ml/s；
2) the flow debugging technique before whole welding type pressurized strut welding is broken through, further gropes E chamber runner streams for the later stage
Amount debugging, the geometrical factor for finding influence flow and its matching create condition.
