Technical field
The present invention relates to a kind of attaching/detaching apparatus used in narrow cylinder barrel long, belong to Automatic manual transmission technical field of tools.
Background technology
Pressurized strut is a kind of hydraulic pressure that the hydraulic energy of input is changed into mechanical energy, straight reciprocating motion or oscillating motion is done
Device.It is substantially made up of cylinder and cover, piston and piston rod, sealing device, buffer unit and exhaust apparatus.Pressurized strut
Use is quite varied on board the aircraft, and during undercarriage control, the effect of bumper and absorbing shock is realized in pressurized strut, it is ensured that motion is flat
Surely.
The endoporus of the pressurized strut cylinder of undercarriage have 1 meter it is deep, and be blind hole, the openend of blind hole sets cover, in blind hole
End cylinder bottom surface on be provided with a small through hole.Piston is located at the bottom of blind hole, cannot be completed using general utility tool
Dismounting, can only first be tapped at the small through hole of end, allow piston to loosen by vibration, be torn open with general utility tool by force again afterwards
Unload.This dismounting mode easily damages the aluminum piston of thin-walled and start barrel is scratched, and inefficiency.
The content of the invention
It is an object of the invention to provide the piston attaching/detaching apparatus in a kind of pressurized strut, conveniently piston can be torn open
Under, protect start barrel not to be scratched, piston is not damaged by, and improves operating efficiency.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of piston attaching/detaching apparatus in pressurized strut, it includes pulling claw, interior trombone slide, outer branch pipe, positioning sleeve and swivel nut, described
Outer branch pipe is a hollow straight tube, and interior trombone slide is coaxially installed in outer branch pipe, and one end end of interior trombone slide is set in convenient promotion draws
The handwheel of pipe axial movement, the other end of interior trombone slide is coaxially extended a mandrel, and the pulling claw is by suit at outer branch pipe end
In the end of outer branch pipe, branch pipe is multiple claws of axle center circumference uniform distribution setting, claw beyond pulling claw includes for the support connection in portion
One end be hinged on support, the other end of claw gathers setting in the extension spring of extended state by one to center, and outer branch pipe is remote
The positioning sleeve being equipped with pressurized strut is provided with from the other end of pulling claw, swivel nut is sleeved on the outer branch pipe on the outside of positioning sleeve.
Piston attaching/detaching apparatus in above-mentioned pressurized strut, the support casing is located at outer branch pipe mounted in the end of outer branch pipe, support
The one end in outside sets pulling claw；The other end of support sets the positioning disk for being set with outer branch pipe and matching with pressurized strut inwall,
The periphery of positioning disk sets the cushion rubber of the frictional force of contact surface between increase positioning disk and pressurized strut.
Piston attaching/detaching apparatus in above-mentioned pressurized strut, the mandrel stretches out setting away from the end of one end of interior trombone slide

With the homonymy of swivel nut 15.
The outer branch pipe 11 is a hollow straight tube, and support 7, the support is fixedly installed in the end of one end of outer branch pipe 11
7 is the sleeve of a convex shape, and the traverse of support 7 is coaxial with outer branch pipe 11 equipped, i.e. the top of the convex shape of sleeve and outer branch pipe 11
It is fixedly linked, the bottom connect setting pulling claw 3 of convex shape.Rubber cushion 4 is fixedly installed in the bottom of convex shape, in making for attaching/detaching apparatus
Rubber cushion 4 and the side end face directly contact of piston 19, prevent from colliding with during.Pulling claw 3 uses bakelite material in the present embodiment, keeps away
Exempt to damage piston.The pulling claw 3 includes multiple claws, and the quantity of claw can set six, institute with unrestricted choice in the present embodiment
It is axle center circumference uniform distribution around setting to have branch pipe 11 beyond claw, and it is convex that one end of each claw is hinged on support 7 by a pin 5
The bottom of font, the equal vertical axis of the other end of claw installs extension spring 2 in through-holes through a through hole is set, and extension spring 2 is in stretching
State, causes that all claws are gathered to center by the restoring force of extension spring 2, mandrel 1 is centered around interior.In the convex shape of support 7
Top side be fixedly installed center band through hole disc structure positioning disk 9, the positioning disk 9 by through hole be set with fix
Set on outer branch pipe 11, the periphery of positioning disk 9 is engaged with the inwall of pressurized strut 18.Set in the outlet of positioning disk 9
There is cushion rubber 8, the frictional force for increasing contact surface between positioning disk 9 and pressurized strut 18.
The end of the other end of outer branch pipe 11 is fixedly installed swivel nut 15, and swivel nut 15 is connected through a screw thread suit in outer branch pipe 11
On.The outer wall of swivel nut 15 is fixedly installed hand 14, facilitates spinning in and out swivel nut 15.Swivel nut 15 is set near the inner side of pressurized strut 18
Positioning sleeve 12, the suit of the positioning sleeve 12 is fixed on outer branch pipe 11, and positioning sleeve 12 is equipped with the opening of pressurized strut 18, this implementation
The mode of threaded connection is taken to be coordinated in example, for ensureing attaching/detaching apparatus in use and pressurized strut 18 and piston 19
Keep concentric, prevent from colliding with, convenient use.The outside of positioning sleeve 12 abuts against with the inner side of swivel nut 15, in swivel nut 15
Side sets the thrust bearing 13 being equipped with outer branch pipe 11, thrust bearing 13 and the outside phase apical grafting of positioning sleeve 12, lightens one's labor strong
Degree.
Interior trombone slide 10 is coaxially installed in outer branch pipe 11, and interior trombone slide 10 sets handwheel with one end end of the homonymy of swivel nut 15
17, rotation hand wheel 17 promotes interior trombone slide 10 to move axially.Nut is set on interior trombone slide 10 between handwheel 17 and swivel nut 15
16, nut 16 is engaged with swivel nut 15, and nut 16 is fixedly linked with swivel nut 15 in use, prevents swivel nut 15 and positioning sleeve
12 loosen.
