Abstract
The utility model discloses a kind of detachable lid sealing process unit, including technique screw rod and wing nut, wing nut and packing ring are linked on technique screw rod, and technique screw rod lower part, which is arranged to set up separately in the middle part of thread segment one, is equipped with thread segment two, and wing nut bottom is provided with taper platform.The detachable lid sealing process unit can avoid sealant from flowing into or be brought into airtight plate nut, ensure installation screw not bursting rubber seal cover easily, the life-span of airtight plate nut is set to increase significantly, simultaneously, the taper platform of wing nut lower end is drawn nest with covering and matched, the sealing installation of installation screw can be simulated, and prevents covering from drawing nest and being damaged.
Description
Technical field
The utility model belongs to airplane hatch cover assembling processing technique field, and in particular to a kind of detachable lid sealing recruitment
Process and equipment.
Background technology
The use of integral tank is on board the aircraft becoming for future development with the development of Aeronautics and Astronautics field science and technology
Gesture., it is necessary to consider integral tank is safeguarded and checked in aircraft flight in fuselage integral tank design process, therefore,
The construction of integral tank usually requires to be equipped with detachable lid.And the sealing of integral tank annoyings researchers invariably,
If design, selection, technique, inspection are incorrect, it will cause seepage consequence, the sealing assembling of particularly detachable lid.Can
Dismantle in lid sealing assembling process, the less sealant of viscosity can be brought into airtight plate nut by screw, to be sealed dose
After vulcanization, tightened repeatedly by screw or fuel oil is flowed into airtight plate nut after being swelled, its rubber seal cover will be by
Bursting, so as to cause fuel tank seepage, so as to a major hidden danger as aircraft integral tank seepage.
In existing technology, to avoid containing in airtight plate nut sealant, most technology considers can be in mouth
Before sealant being smeared on frame, with hairbrush toward interleaving agent (ointment etc.) is applied in airtight plate nut, after then waiting sealant vulcanization,
The sealant in airtight plate nut is ticked using crochet hook, although although making to incite somebody to action to a certain extent in this way
Most of sealant, which is ticked, to be come, but relatively complicated, and be very dependent on worker handicraft and work attainment, it is necessary to spend big
The time of amount, eventually reduce the production efficiency of company.
Utility model content
Existing sealant is overcome to be brought into airtight plate nut to solve the above problems, the utility model provides one kind
In technical problem, ensure the detachable lid sealing process unit of airtight plate nut sealing property.
A kind of detachable lid sealing process unit, including technique screw rod and wing nut, wing nut and packing ring set
Close on technique screw rod, technique screw rod lower part, which is arranged to set up separately in the middle part of thread segment one, is equipped with thread segment two, wing nut bottom
It is provided with taper platform.
Further, the technique screw tip of the detachable lid sealing process unit be positive square head or positive six square toes with
Wrench socket matches.
Further, the detachable lid sealing is 30CrMnSiA, σ b=with the technique screw tip material of process unit
1175 ± 100MPa, wing nut material are Q235.
Had the beneficial effect that by what the technological means the utility model obtained, process unit energy is used in the detachable lid sealing
Enough avoid sealant from flowing into or be brought into airtight plate nut, ensure installation screw not bursting rubber seal cover easily, make gas
The life-span of close plate nut increases significantly, meanwhile, taper platform and the covering of wing nut lower end are drawn nest and matched, and can simulate installation
The sealing installation of screw, and prevent covering from drawing nest and being damaged.

Embodiment
A kind of detachable lid sealing process unit, including technique screw rod 1 and wing nut 2, the fit of wing nut 2
On technique screw rod 1, the lower part of technique screw rod 1, which is arranged to set up separately in the middle part of thread segment 1, is equipped with thread segment 23, under wing nut 2
Portion is provided with taper platform 5.
Tighten or untie for convenience, it is easy to operation, improve applicability.The technique of the detachable lid sealing process unit
The top of screw rod 1 matches for positive square head or positive six square toes with wrench socket.
For enhancing structure intensity, increase the service life.The top of technique screw rod 1 of the detachable lid sealing process unit
Material is 30CrMnSiA, and σ b=1175 ± 100MPa, the material of wing nut 2 is Q235.
In use, purpose made technology screw rod 1 is screwed into the internal thread of the airtight plate nut of aircraft, non-sulphur on mouthful frame is avoided
The sealant of change is brought into the airtight plate nut of aircraft, meanwhile, bondline thickness is controlled by special wing nut 2 is twisted, is treated close
After sealing agent vulcanization, purpose made technology screw is removed, and installation screw is installed.
The scope of protection of the utility model is not limited only to the technical scheme disclosed in specific embodiment part, all to use work
The scheme that skill screw (screw rod, wing nut) carries out removable seal assembling each falls within the scope of protection of the utility model.
