Description
Technical field
This utility model relates to hydraulic cylinder technical field, is specially a kind of hydraulic cylinder preventing clogging up device.
Background technology
Hydraulic energy is changed into mechanical energy, does the liquid of straight reciprocating motion (or oscillating motion) by hydraulic cylinder
Pressure executive component.Its simple in construction, reliable operation.When realizing moving back and forth with it, deceleration can be removed from
Device, and there is no drive gap, stable movement, therefore obtain wide in the hydraulic system of various machineries
General application.The pressure reduction on hydraulic cylinder power output and piston effective area and both sides thereof is directly proportional；Hydraulic cylinder is substantially
It is made up of with exhaust apparatus cylinder barrel and cylinder cap, piston and piston rod, sealing device, buffer unit.Buffering
Device and exhaust apparatus are depending on concrete application scenario, and other devices are the most essential.Cylinder barrel is as hydraulic pressure
The critical piece of the products such as cylinder, mining single prop, hydraulic support, gun tube, the quality of its crudy
Directly affect the life and reliability of whole product.Cylinder barrel processing request is high, its inside surface roughness requirement
For Ra0.4～0.8µ；M, requires strict to axiality, wearability.The basic feature of cylinder barrel is deep
Hole machined, processing staff is perplexed in its processing always.Oil cylinder is the main parts of engineering machinery, and traditional adds
Work method is: broaching cylinder body right boring cylinder body grinding cylinder body.Employing rolling depression method is: broaching cylinder
Body right boring cylinder body rolling cylinder body, operation is 3 parts, but time upper contrast: grinding cylinder body 1
Rice is general the time of 1-2 days, and rolling cylinder body 1 meter is probably the time of 10-30 minute.Put into and contrast:
Grinding machine or hone machine (several ten thousand is millions of), rolling depression cutter (1000 more than ten thousand).After rolling, hole surface
Roughness is by Ra3.2～6.3µ before building rolling；M is reduced to Ra0.4～0.8µ；M, the surface in hole
Hardness improves about 30%, and cylinder barrel inner surface fatigue strength improves 25%.If oil cylinder only considers cylinder barrel service life
Impact, improves 2～3 times, and boring rolling technology relatively grinding process efficiency improves about 3 times.Data above
Illustrating, rolling technology is efficient, can be greatly improved the surface quality of cylinder barrel.Piston is in hydraulic cylinder
Motion there will be inevitably abrasion repeatedly, and these can quilt due to the produced tiny iron filings of abrasion
It is sent in outlet line, the obstruction of flowline can be caused so that hydraulic mechanism is short of power the most in the past,
Affect usefulness.

RunddichtringO, and dirt-proof boot contacts with cylinder interior surface with O RunddichtringO, described dirt-proof boot surface sets
Having sealing gasket, and sealing gasket upper surface contacts with inner chamber of cylinder block surface, described O RunddichtringO is positioned at dust-proof
On the right side of set, described piston rod top is provided with piston, and described piston face is provided with wear ring, and wear-resisting
Ring upper surface contacts with inner chamber of cylinder block surface, and described cylinder surface has oil-out, bottom described oil-out
Being provided with filtering grid plate, described filtering grid plate top is provided with floating seal, in described oil-out two
Sidewall is respectively equipped with projection.
Preferably, described sealing gasket is Y shape sealing gasket.
Preferably, described piston high-frequency welding is on the top of piston rod.
Preferably, the aperture of described filtering grid plate is 0.02 millimeter.
Compared with prior art, the beneficial effects of the utility model are: this hydraulic cylinder preventing clogging up device is being lived
Plug surface is mounted with wear ring, can reduce the impurity such as the iron filings that produce due to friction to greatest extent,
At oil-out, arrange filtering grid plate can effectively the impurity such as iron filings be filtered, prevent it from blocking
Outlet line, affects the usefulness of hydraulic mechanism.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is A portion schematic enlarged-scale view.
In figure: 1 cylinder body, 2 piston rods, 3 sealing gaskets, 4 dirt-proof boots, 5O shape sealing ring, 6 pistons,
7 wear rings, 8 oil-outs, 9 filtering grid plates, 10 floating seals, 11 projections.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Referring to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of hydraulic cylinder preventing clogging up device,
Including cylinder body 1, cylinder body 1 is internal is provided with piston rod 2, and it is close that piston rod 2 surface is provided with dirt-proof boot 4 and O type
Seal 5, and dirt-proof boot 4 contacts with cylinder body 1 interior surface with O RunddichtringO 5, dirt-proof boot 4 surface sets
Having sealing gasket 3, and sealing gasket 3 upper surface contacts with cylinder body 1 surface of internal cavity, O RunddichtringO 5 is positioned at anti-
On the right side of dirt set 4, piston rod 2 top is provided with piston 6, and piston 6 surface is provided with wear ring 7, and resistance to
Bull ring 7 upper surface contacts with cylinder body 1 surface of internal cavity, and cylinder body 1 surface has oil-out 8, oil-out 8 end
Portion is provided with filtering grid plate 9, and filtering grid plate 9 top is provided with floating seal 10, oil-out 8 liang
Medial wall is respectively equipped with projection 11.Sealing gasket 3 is Y shape sealing gasket.Piston 6 high-frequency welding is at piston rod
The top of 2.The aperture of filtering grid plate 9 is 0.02 millimeter.
Operation principle: done inside cylinder body 1 by hydraulic drive piston rod 2 and piston 6 and to move in circles
Linear motion, dust-proof cushion 4, the use of sealing ring 3 and O RunddichtringO can reduce outside to greatest extent
Impurity enters the inside of cylinder body 1, ensures the working environment of hydraulic mechanism, wear-resisting in piston 6 surface configuration
The impurity such as the iron filings that ring 7 can reduce piston 6 and cylinder body 1 internal friction as far as possible and produce, piston 6
Due to the effect of pressure during promoting forward so that floating seal 10 moves up, will filter
