Description
Technical field
The present invention relates to technical field of hydraulic oil cylinder, be specifically related to a kind of Novel hydraulic cylinder.
Background technology
Hydraulic system is the important component part of industrial automation, occupies very important status in electromechanical integration,
Pivotal role is played in terms of the dynaflow of industrial automation.Hydraulic jack is to be converted to by hydraulic energy in hydraulic system
Mechanical energy, it is achieved the actuator of straight reciprocating motion.
Hydraulic jack often occurs that the abrasion of cylinder body, piston, piston rod scratches, seals original paper damage inefficacy in the industrial production
Etc. situation, causing oil cylinder to reveal and lost efficacy, service life is short, cost is high, and the rear-bank rotor housing that lost efficacy, piston, piston rod are substantially without repairing
Multiple being worth, matrix can not reuse, service life is short,.Utilize it addition, cylinder body generally requires professional with piston when assembling
Special tooling assembles, and often occurs being difficult to pack into or damage the situations such as sealing original paper.
Hydraulic jack the most all uses conventional hermetic element (O and Y-shaped ring etc.) to be designed, cylinder body, piston (bar),
Cylinder cap easily produces abrasion, scratches, and potted component easily damages and lost efficacy, and often results in seal failure and oil cylinder matrix damages,
Cause hydraulic system fault occurred frequently, have a strong impact on normal production operation.It is thus desirable to the internal structure of oil cylinder is carried out new setting
Meter, to reduce the abrasion of piston rod, to improve the service life of hydraulic cylinder, meets higher use requirement.
Summary of the invention
Present invention solves the technical problem that to be to provide a kind of functional reliability height, length in service life, recycling rate of waterused high
Novel hydraulic cylinder.
The present invention solves above-mentioned technical problem and be the technical scheme is that
A kind of Novel hydraulic cylinder, including cylinder body, piston, also includes piston gland and piston rod gland, described piston pressure
Cover and be connected by screw II with between piston, be connected by screw I between described piston rod gland with oil cylinder cylinder cap, can pass through
Adjust screw II and screw I regulates cylinder efficient pressure, after exceeding the time limit to use, oil cylinder cylinder cap pressure can be adjusted by screw II and I
It is continuing with；Twice piston combination seal, described cylinder block it is provided with between described piston gland and piston and cylinder body
And it is provided with two piston rod combination seals between piston rod and piston rod gland.Cylinder structure design uniqueness, makes each
The installation of sealing member, change more convenient, and automatically compensate after abrasion can be realized, reduce the friction system between each element
Number, is provided with support guide ring I, is provided with guide ring II between described oil cylinder cylinder cap and piston rod between described piston and cylinder body, protect
Having demonstrate,proved centering, anti-bias load lotus ability is obviously enhanced, and effectively prevent abrasion and scratches.
Further, in such scheme, described piston sealing member is piston combination seal, two seals part it
Between be provided with spacer, spacer is provided with support guide ring I.
Further, in such scheme, described piston rod sealing member is piston rod combination seal, twice piston
It is provided with spacer ring between bar sealing member.This sealing has compensation automatically after good seal performance, abrasion, high abrasion, the high life, low
Friction, corrosion-resistant, high temperature resistant and low temperature, leak free feature, be highly suitable for hydraulic packing, can meet more stringent making
Use environment.
Further, in such scheme, described piston rod gland is provided with axle dust ring.
Further, in such scheme, described cylinder body end face is provided with axial right-angle array and seals and O RunddichtringO.
Further, described axial right-angle array seals (1) is axial right angle sliding ring assembled seal.
Compared with prior art, beneficial effects of the present invention is embodied in:
First, service life is apparently higher than domestic like product.The cylinder seal original paper of present invention design can realize abrasion
Rear compensation automatically, eliminates the phenomenons such as conventional oil cylinder friction factor is big, easy to wear, potted component easily overturns, plastic cement extrusion and makes
By defects such as temperature range are little；Cylinder body and piston rod use chromium plating to process technique, significantly enhance matrix abrasion resistance properties.Piston
The axle dust ring arranged on bar gland not only can effectively prevent outside iron filings, sand grains etc. to sealing the damage of original paper, and from
Body can individually bear the seal pressure of 20Mpa, makes oil cylinder significantly extend service life；The axial right angle group that cylinder body end face is arranged
Close and seal and O RunddichtringO forms double-layer seal, make oil cylinder be arranged on lathe matrix to seal relatively reliable, the time is longer, solve
The technical problem that like product seal face of having determined easily is revealed.Domestic like product service life when lathe running at full capacity
Generally 3 months, and the oil cylinder of present invention design reaches 1 year minimum service life, greatly reduces hydraulic system maintenance time
Number, improves equipment operation efficiency, reduces production cost and puts into.
Second, seal pressure is high, sealing scalable.The cylinder efficient pressure of domestic like product design only up to reach
To 35MPA, the cylinder efficient pressure of the present invention then can carry out appointing by adjusting screw II and screw I between 0～70MPA
Meaning regulation, can adjust cylinder seal pressure by screw after exceeding the time limit to use and be continuing with；Use pressure limit higher than conventional oil
Cylinder, can meet more working condition simultaneously, and this is not available for domestic like product.
3rd, reasonable in design, install, change conveniently.Domestic like product typically requires and is used specially by professional
Carry out installing, changing with instrument, and easily cause sealing ring to damage, and the oil cylinder of present invention design uses unique open type knot
Structure design, make sealing ring installation, change more convenient, it is not necessary to specific purpose tool, general maintainer can complete.
4th, oil cylinder matrix is the most easy to wear, scuffing, is truly realized matrix and reuses.The oil cylinder of present invention design
Body coordinates with the employing wide arc gap that coordinates of piston rod with piston, cylinder body, seals the structure shape with support guide in conjunction with bilayer combination
Formula makes the centering of oil cylinder, anti-bias load lotus ability be obviously enhanced, and efficiently solves the technical barrier of like product matrix easy damaged,
Sealing excellent realization of matrix after original paper reaches service life to reuse, greatly reduce cost, this is domestic similar product
Performance not available for product.
5th, more stringent use environment can be met.Use temperature the highest under conventional oil cylinder kinestate is general
Being 60～80 DEG C, Efficient lathe oepration at full load oil temperature the most all can be maintained at about 50～60 DEG C, therefore the making of like product
Can have a greatly reduced quality with the life-span, hence it is evident that reduce, and the oil cylinder of present invention design uses temperature to be-55 DEG C～250 DEG C, meets extremely low
Use requirement at temperature and worst hot case, hence it is evident that be better than domestic like product.
