Description
Technical field
The invention belongs to conduits to repair fixture manufacturing field, provide a kind of interior bulging formula conduit circularity finishing fixture.
Background technique
In aircraft processing and manufacturing assembly, aircraft conduit class part category and quantity are various, catheter shape, specification, material
Etc. different, every conduit needs the production by several process that could complete, and the manufacturing cycle is longer.Since conduit is curved
Conduit is damaged, is made in the processing and manufacturing such as welding, in process turnover, during aircraft maintenance and examine in circular flow by song
It happens occasionally, can not be repaired since recessed position is not at catheter end head, so that part report at the phenomenon that conduit local dent
It is useless, it causes to waste, the production cycle that processing of going into operation again again needs to grow very much again, influences manufacturing schedule and use.According to above-mentioned
Problem has invented interior bulging formula conduit finishing fixture, using interior bulging structure, repairs recess conduit, reduces waste product, save material,
Guarantee production.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of interior bulging formula conduit circularity finishing fixture, this is interior swollen
Form conduit circularity finishing fixture is applicable in aircraft Pneumatic Transmission, the impaired finishing of conduit circularity in hydraulic drive pipeline.
In order to achieve the above object, the technical solution of the present invention is as follows:
A kind of interior bulging formula conduit circularity finishing fixture, for modifying the conduit of impaired recess, the interior bulging formula conduit circle
Spending finishing fixture includes handle 1, sleeve 2, connecting shaft 3, universal joint 4, pin 5, push rod nut 6, hole retaining ring 7, six flap-type expansion sets
8, tapered sleeve 9, expanding ring 10, axis of cone screw rod 11.
Interior bulging formula conduit circularity finishing fixture left and right ends symmetrical configuration, the handle 1 of one end are connect with sleeve 2, set
Cylinder inner hole is connect with one end of connecting shaft 3；The other end of connecting shaft 3 is connect with 4 one end of universal joint, and the two is fixed by pin 5, and ten thousand
Xiang Jieke makes transmission direction turn an angle transmission；4 other end of universal joint connects push rod nut 6, and interior spiral shell is made in push rod nut 6
Line, internal screw thread and axis of cone screw rod 11 are cooperatively connected, and axis of cone screw rod 11 passes through tapered sleeve 9 and connect with push rod nut 6, and push rod nut 6 is logical
Via hole retaining ring 7 is fixed on tapered sleeve 9；Tapered sleeve 9, axis of cone screw rod 11 are installed along on six flap-type expansion sets 8, six flap-type expansion sets 8
Six flap-type of equal part is made, there are two expanding rings 10 for dress on six flap-type expansion sets, 8 outer diameter, six flap-type expansion sets 8 are formed a whole,
Reset response is played when reset；11 universal-joint 4 of axis of cone screw rod, it is fixed by pin 5.
Use process of the present invention are as follows: after connecting interior bulging formula conduit circularity finishing fixture, one end does not fill handle first
1, never mounting knob end, fixture is put into and is wanted in modified conduit, fits a handle on 1.Two people's operations at this time, a people hold
One end handle, a people rotate other end handle, and universal joint 4 drives push rod nut 6, and push rod nut 6 compresses tapered sleeve 9 and tenses cone
Axis screw rod 11, six flap-type expansion sets 8 diameter under the action of tapered sleeve 9 and the axis of cone 11 conical surface of screw rod increases outside bulging, recessed when being damaged
When sunken conduit reaches conduit diameter, handle 1 stops rotating, and after handle 1 is reversely rotated four or five circles, pulls out fixture,
Six flap-type expansion sets 8 reset under the action of expanding ring 10, pull out fixture.
The invention has the benefit that the present invention uses six flap-type expansion set structures, outside is equipped with expanding ring, and structure is tight
It gathers, bulging is withdrawn freely, inside has tapered sleeve, axis of cone screw rod and six flap-type inner conical drogues to cooperate, bulging power is big, not only using universal joint
Straight tube diameter can be repaired, it can also be to there is certain bending angle conduit diameter to modify.
Detailed description of the invention
Fig. 1 is interior bulging formula conduit circularity finishing fixture structural schematic diagram；
Fig. 2 is the cross-sectional view in the direction A-A in Fig. 1.
Specific embodiment
The present invention will the present invention will be further explained in conjunction with attached drawing and specific embodiment, embodiment and attached
Figure cannot be construed as the limitation to invention protection scope merely to further explanation technical solution of the present invention.
A kind of interior bulging formula conduit circularity finishing fixture, for modifying the conduit of impaired recess, the interior bulging formula conduit circle
Spending finishing fixture includes handle 1, sleeve 2, connecting shaft 3, universal joint 4, pin 5, push rod nut 6, hole retaining ring 7, six flap-type expansion sets
8, tapered sleeve 9, expanding ring 10, axis of cone screw rod 11.Handle 1 is connect with sleeve 2, and hub internal bore is connect with one end of connecting shaft 3；Even
