Description
Technical field
The present invention relates to hydraulic cylinder field, deoil the hydraulic cylinder of outer abrasion more specifically to a kind of tilting.
Background technique
Hydraulic cylinder is the hydraulic actuator that hydraulic energy is changed into mechanical energy, does straight reciprocating motion.With knot
The characteristics of structure is simple, reliable operation.Deceleration device when realizing reciprocating motion, can be removed from hydraulic cylinder, and be not driven
Gap, movement is steady, therefore being used widely in the hydraulic system of various machinery.Hydraulic cylinder power output and piston have
The pressure difference for imitating area and its both sides is directly proportional；Hydraulic cylinder is substantially by cylinder barrel and cylinder cap, piston, piston rod and sealing device group
At.
Hydraulic cylinder oil leak longest as be in oil caused by abrasion and the outer abrasion of oil.Impurity in oil is embodied in tripartite
Face, first: can all have metal impurities in hydraulic station in fluid pressure line after the installation is completed for the first time, be had to before booting at this time clear
Reason finishes, and gives pipeline pressure test.Second: the permanent work of control valve, metal tubes, metal component on hydraulic in high pressure oil
Under, some component outer walls can be peeled off, and be acted on sealing ring into hydraulic oil.Third: due to tank cover or air
The headkerchief of filter is fitted without, and indoor impurity dust is caused to enter fuel tank.
Oily outer abrasion refers to the abrasion sealing ring of the metal impurities on piston rod.
The more severe workshop of some working environments has a large amount of impurity adherency on the piston rod, when such piston rod is shunk,
Impurity and sealing ring friction, some are even ground away piston rod, and more serious influence is caused.So outside sealing ring at piston rod
Face can add one group of dustband, although dustband can play a certain protective role, protective effect is not strong, ineffective.
Summary of the invention
1. technical problems to be solved
Aiming at the problems existing in the prior art, it deoils the hydraulic oil of outer abrasion the purpose of the present invention is to provide a kind of tilting
Cylinder, it adds self-cleaning rotating cylinder in the output end of cylinder body of hydraulic oil cylinder, and skewed cleaning brush is clear in the contraction process of piston rod
The impurity of clean piston rod surface adherency, and the inclined direction of skewed cleaning brush and the shrinkage direction of piston rod are on the contrary, reinforce
Cleaning dynamics；When piston rod extends, skewed cleaning brush bristle is pressed downward by piston rod, and the impurity adhered on bristle is transferred to
From storage villus, curly can firmly cling impurity from storage villus, prevent impurity is counter from adhering to piston rod surface, keep piston
The cleannes on bar surface reduce the outer abrasion of oil, improve hydraulic cylinder job stability.
2. technical solution
To solve the above problems, the present invention adopts the following technical scheme that.
A kind of tilting deoils the hydraulic cylinder of outer abrasion, and the cylinder body of hydraulic oil cylinder of piston rod is connected with including output end,

Further, the horizontal tilt degree of the cleaning brush is 55 ° -60 °, and suitable inclination angle can further strengthen cleaning
Dynamics, when tilt angle is too small, the gap between adjacent bristle is also too small accordingly, is adhered to biggish miscellaneous on piston rod surface
Matter is not easily accessible between bristle, that is, is not easy to be cleaned out, cleaning effect is bad；When tilt angle is excessive, bristle is in piston rod
The dynamics on cleaning piston bar surface is bad in contraction process, and cleaning effect is equally bad.
Further, the cleaning brush is uniformly connected with multiple from storage villus close to the side of cylinder body of hydraulic oil cylinder, and from
Storage villus is curly, the impurity of cleaning brush cleaning piston bar surface adhesion in the contraction process of piston rod, piston rod surface
The impurity of adherency is transferred to side of the cleaning brush far from cylinder body of hydraulic oil cylinder；When piston rod extends, piston rod will be skewed clear
Clean brush bristle is pressed downward, and the impurity adhered on bristle is transferred to from storage villus, and curly can be by impurity firmly from storage villus
It clings, prevents impurity is counter from adhering to piston rod surface.
Further, the diameter from storage villus is the one third of cleaning brush diameter, from storage villus reasonable size
Design guarantees that cleaning brush when cleaning piston bar surface, will not be prevented in piston rod contraction process from villus is stored up with plunger rod contacts
It is only sticky to be adhered on piston rod from storage villus, cause unnecessary oil is outer to wear.
Further, described to be made from storage villus using the compound of natural gum and glycerol resin, and natural tree
The ratio of glue and glycerol resin is 1-1.5:2-3, guarantees firmly glue impurity from the storage good adhesiveness of villus itself
Firmly, cleaning effect is more preferably.
Further, the self-cleaning rotating cylinder is made using rigidifying glass, and the cleaning brush is made of transparent plastic
Form, it is described from storage villus be pure white, using rigidifying glass production made of self-cleaning rotating cylinder and using transparent plastic production and
At cleaning brush can keep good transparency, convenient for operator from inside the self-cleaning rotating cylinder of external observation impurity adhere to shape
State, it is lily from storage villus equally facilitate operator from external observation from store up villus on impurity coherent condition.
Further, using the connection type of clamping between the self-cleaning rotating cylinder and fixed ring, when being adhered on cleaning brush
When more impurity, operator can remove self-cleaning rotating cylinder, replace cleaning brush, guarantee the cleaning piston that cleaning brush can be continual and steady
The impurity of bar surface adhesion keeps the cleannes of piston rod surface, reduces the outer abrasion of oil, improves hydraulic cylinder job stability.
Further, the cylinder body of hydraulic oil cylinder surface is coated with advanced corrosion-inhibiting coating, and advanced corrosion-inhibiting coating can protect liquid
