Description
Technical field
The invention belongs to the technical fields of Automatic manual transmission manufacture, and in particular to a kind of omnipotent extracting tool of small impingement torsion
And application method.
Background technique
During aircraft assembling manufacturing, it is related to hundreds of thousands of a screws, bolt needs to carry out assembly or disassembly, by institute
Screw and bolt be all to carry out assembly or disassembly using pneumtic impact wrench, sometimes due to the tension on screw, add aircraft
It carries out after flying for a long time, the screwing force of part screw or bolt increases, and therefore, when needing to remove somewhere screw, makes
It is sometimes difficult to remove on screw, bolt with common wind plate machine, and because part screw belongs to counter-sunk screw, except through head of a nail institute band
A word or the cross edge of a knife can be removed, it is desirable to certain a part for clamping screw is removed, and is practically impossible to.At present
Conventional method is first to use common pneumtic impact wrench, be adjusted to large impact, the low gear of large torque is dismantled, if still
It cannot be removed, hammer must be used to carry out beaing the screw that cannot be removed, then reuse wind plate machine and dismantled, if
If still not all right.Pressure wrench must be used at this time, first find a leverage points on periphery, then pushing down by force again cannot remove
Screw, then dismantled.But suitable lever cannot be found by being limited sometimes by the shape of skin-surface and the withdrawal space
Point, therefore must bore by the head of a nail using drill bit, then plate nut is bored again, rivets a new supporting plate spiral shell again
Mother, has reached matching requirements, but practical when boring the head of a nail, invisible in this way to work as since the drill bit for needing hand to turn is coaxial with screw
In increase very big difficulty, therefore it is extremely difficult to operate.

Be the mode being spirally connected, and presently, there are related tool be all integral type, as long as round stopper 6 is once breakage, entire work
Tool will just be scrapped, on the contrary, round stopper 6 need to only be changed new accessory i.e. by the omnipotent extracting tool of small impingement torsion of the invention
Can, the service life of the tool is not only extended, but also also a save cost.
(3) due to the quick-release coupling of the internal diameter rotator 2 of the omnipotent extracting tool of small impingement torsion of the invention, pass through ten thousand
Can crossover sub 1 can be attached with the cutter head of the working methods such as a word of any model, cross, set copper sleeve, therefore can
By solve the problems, such as it is any in the form of union piece be difficult to dismantle.
(4) since the omnipotent extracting tool of small impingement torsion of the invention is the strong impact force that will act at round stopper 6,
It is converted into strong impact force and large torque power is exported, which is the power of moment, the constant impingement power and torsion phase with pneumtic impact wrench
Than not only the size of power increased, but also the impact force of moment and torsion can damage to avoid the edge of a knife of screw or bolt.
(5) it due to the versatility of the omnipotent extracting tool structure of small impingement torsion of the invention, can not only be widely applied
Field is assembled to aircraft manufacturing, also can be generalized to the other machineries assembling manufacturing such as civilian, ship, high-speed rail, space flight field.
