Simple structure, resistance to corrosion and high temperature resistance can be good, and the cylinder inner wall is all through finish grinding, and is smooth bright damp, sealing washer durable, small, installation space is little, and clearance fit is accurate, and the wearing and tearing of reduction dust ring, the ageing pretightning force that leads to reduce to extension hydro -cylinder life improves the reliability of hydro -cylinder action.
Description
Technical field
The utility model relates to a kind of mini mesolow oil cylinder.
Background technique
The history that the manual excavator of First comes out existing more than 130 year so far, period experienced by by steam driven bucket revolving shovel to electric drive and internal combustion engine drive revolving shovel, the progressively evolution of applying the fully automatic hydraulic excavator of mechanical-electrical-hydraulic integration technology.Oil cylinder and oil hydraulic cylinder, oil hydraulic cylinder is the straight line moving type executive component that the pressure reduction on ouput force and piston effective area and both sides thereof is directly proportional.Be widely used in mold center, frock clamping, mineral products are metallurgical, machine-building, petrochemical industry, quay transportation, and water power is built, light industry manufacture, papermaking printing, the liquid gas pressure transmission fields such as space flight and aviation,
Current most of oil cylinder is all that employing lip dust ring is outwardly to prevent entering of environmental contaminants, because dust ring has a pretightening force to piston rod surface, when piston rod rollback, the moisture film of pretightening force to piston rod of dust ring has one to scrape crowded power, dirt is scraped off from piston rod, because the pretightening force of dust ring is produced by dust ring resiliently deformable, so the pretightening force of dust ring is very little, when dust ring wearing and tearing, aging cause pretightening force to reduce or the movement velocity of piston rod is too fast time, at this moment piston rod every action capital is brought little water into and is entered hydraulic system, frequent movement accumulation will cause a large amount of dust to enter hydraulic system, cause the rotten of hydraulic oil, cylinder piston rod at work simultaneously, directly be fixedly connected with the mechanical part that will drive by piston rod, both are often through being threaded, but, in transport, in operating process, easily cause the colliding with of piston rod, damage, affect the reliability of cylinder action.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of anticorrosive property and resistance to high temperature good, inner wall of cylinder all through fine grinding, smooth glossy mini mesolow oil cylinder.
The utility model solves the technological scheme that its technical problem adopts: a kind of mini mesolow oil cylinder, there is cylinder barrel, the two ends of described cylinder barrel are provided with protecgulum and bonnet, piston rod is provided with in cylinder barrel, one end of piston rod is provided with piston, the other end of piston rod is provided with outside thread, protecgulum and piston rod joint are provided with axle oil and seal, axle seal ring and holding without glossy live axle, piston and cylinder barrel joint are provided with piston ring and wear ring, piston is fixed on the piston rod by SPRING WASHERS and nut, cylinder barrel offers hydraulic fluid port, the two ends of described protecgulum and the joint of cylinder barrel are equipped with " O " type ring.
Further, described piston rod and piston joint are provided with "O"-ring.
Further, the outer surface of described cylinder barrel is provided with chromium coating, and cylinder barrel adopts stainless steel material to make.
The beneficial effects of the utility model are: the utility model structure is simple, anticorrosive property and resistance to high temperature good, inner wall of cylinder is all through fine grinding, and smooth glossy, seal ring is durable in use, volume is little, installing space is little, and Spielpassung is accurate, reduces dust ring wearing and tearing, the aging pretightening force caused reduces, thus extend oil cylinder working life, improve the reliability of cylinder action.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. cylinder barrels, 2. protecgulum, 3. bonnet, 4. piston rod, 5. piston in figure, 6. axle oil envelope, 7. axle seal ring, 8. holds without glossy live axle, 9. piston ring, 10. wear ring, 11. SPRING WASHERS, 12. nuts, 13. hydraulic fluid ports, 14. outside threads, 15. "O"-rings, 16. chromium coatings, 17. " O " type ring.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
The mini mesolow oil cylinder of one as shown in Figure 1, there is cylinder barrel 1, the two ends of described cylinder barrel 1 are provided with protecgulum 2 and bonnet 3, piston rod 4 is provided with in cylinder barrel 1, one end of piston rod 4 is provided with piston 5, the other end of piston rod 4 is provided with outside thread 14, protecgulum 2 and piston rod 4 joint are provided with axle oil and seal 6, axle seal ring 7 and hold 8 without glossy live axle, piston 5 and cylinder barrel 1 joint are provided with piston ring 9 and wear ring 10, piston 5 is fixed on piston rod 4 by SPRING WASHERS 11 and nut 12, cylinder barrel 1 offers hydraulic fluid port 13, described protecgulum 2 is equipped with " O " type ring 17 with the two ends of the joint of cylinder barrel 1, piston rod 4 and piston 5 joint are provided with "O"-ring 15, the outer surface of cylinder barrel 1 is provided with chromium coating 16, cylinder barrel 1 adopts stainless steel material to make.
The two ends of concrete described cylinder barrel 1 are provided with protecgulum 2 and bonnet 3, piston 5 and cylinder barrel 1 joint are provided with piston ring 9 and wear ring 10, piston 5 is fixed on piston rod 4 by SPRING WASHERS 11 and nut 12, , so that dismounting is overhauled, because piston 5 and cylinder barrel 1 have certain interval, adopt wear ring 10 centering pilot supported by nylon, the endoporus of piston rod 3 and piston 4 is sealed by "O"-ring, longer protecgulum 2 can ensure that piston rod 4 does not depart from center, guide sleeve 6 external diameter is sealed by two " O " type ring 17, more effectively preventing oil from leaking outside brings in cylinder with dust, structure is simple, anticorrosive property and resistance to high temperature good, inner wall of cylinder is all through fine grinding, smooth glossy, seal ring is durable in use, volume is little, installing space is little, Spielpassung is accurate, thus extend oil cylinder working life.
