Description
Technical field
This utility model belongs to oil cylinder apparatus technical field, particularly relates to amplitude oil cylinder in one.
Background technology
State's inner cylinder dress valve is all first to weld a valve seat on cylinder body at present, then valve is arranged on valve seat to realize turnover oil and hydraulic control；Mesohigh cylinder tube material typically uses No. 45 seamless pipes, higher running into rated operating pressure, when cylinder barrel wall thickness is inadequate, to thicken cylinder barrel wall thickness as main path, but also results in oil cylinder own wt simultaneously and lays particular stress on, and cost is increased.When in use, piston rod is cylinder interior activity when, and piston rod has part when passing in and out cylinder body, has exposed parts for current oil cylinder, and after using for a long time, the exposed parts of piston rod can have damage in atmosphere owing to exposing.After the long-time use of oil cylinder, each junction of oil cylinder can be worn and torn more serious, thus has a strong impact on the use time of oil cylinder.And, current oil cylinder piston rod during using can be deviate from from cylinder interior, or in use piston rod and the interphase interaction of inner sleeve stoping piston rod to be deviate from cylinder body, after using a period of time, make inner sleeve unstable with the connection of cylinder body, thus piston rod can be made to deviate from cylinder body, affect the use time.
Utility model content
The purpose of this utility model is to solve techniques discussed above problem; there is provided one to make piston rod expose extending area to be effectively protected; improve the presentation quality of oil cylinder; improve the wearability of cylinder bearing; also make bearing pin effectively be lubricated and protect simultaneously; extending the life-span of bearing pin, improve work efficiency, reduce production cost, the upper amplitude oil cylinder that can well prevent piston rod from deviating from from cylinder interior, its technical scheme is as follows:
Upper amplitude oil cylinder, including cylinder body and piston rod, it is characterised in that one end of described cylinder body is connected with cylinder head by bearing pin, it is provided with piston rod in described cylinder body, one end of piston rod is connected with head by bearing pin, and the other end of piston rod is arranged in cylinder body, and this end is provided with saddle, described saddle can slide in cylinder body along inboard wall of cylinder block under the drive of piston rod, one end of saddle is provided with plush copper, and when plush copper contacts with cylinder head, plush copper forms oil-feed groove with inboard wall of cylinder block；The top of described cylinder body is provided with oil pipe, and described oil pipe offers oil filler point, and oil filler point one end of oil pipe is communicated with cylinder interior space by oil-feed groove, is provided with check valve between described oil pipe and cylinder body；It is provided with sliding outer cover at the other end of described cylinder body, described sliding outer cover is fixedly installed on the exposed parts of piston rod, described sliding outer cover is connected with retractable dustproof set, one end of retractable dustproof set is fixedly installed on sliding outer cover, the other end of retractable dustproof set is fixed on the outer wall of cylinder body, along with stretching out of piston rod, retractable dustproof set can be stretched and be stretched for closing and expose the piston rod portion outside cylinder body, a ring-shaped clip locking groove it is provided with on the outer wall of described sliding outer cover, described ring-shaped clip locking groove is possible to prevent piston rod to come off from cylinder interior.
Optimal way, described head and the junction of piston rod are provided with fibre bush；Junction between described cylinder head and cylinder body is provided with fibre bush.
Optimal way, one end of described cylinder body is provided with oil outlet.
Optimal way, between described saddle and inboard wall of cylinder block, place is provided with fibre bush.
The upper amplitude oil cylinder that this utility model provides, when in use, oil-feed groove facilitates the oil in oil pipe to enter into cylinder interior.And saddle can play the effect of sealing so that piston rod can be promoted after cylinder interior oil-feed to move.The Main Function of retractable dustproof set is the presentation quality both having improved oil cylinder, also makes piston rod expose extending area simultaneously and is effectively protected.Sliding outer cover and ring-shaped clip locking groove are mainly used for the stop to piston rod and use; can well prevent piston rod from deviating from from cylinder interior; move it is also possible that piston rod need not carry out clashing into laggard whereabouts with the inner sleeve of cylinder body, piston rod and cylinder body can well be protected, extend its use time.
The further head of this utility model and cylinder head are worn pin shaft hole position and are installed fibre bush, improve the wearability of cylinder bearing, also make bearing pin effectively be lubricated and protect simultaneously, extend the life-span of bearing pin.
Between the further saddle of this utility model and inboard wall of cylinder block, place is provided with fibre bush.So that saddle can be better contact with inboard wall of cylinder block so that the sealing property between saddle and inboard wall of cylinder block is the best.The wearability of saddle can be improved, extend the use time.
This utility model is further provided with oil outlet.So that when saddle slide past oil outlet after, oil can made to flow out cylinder body from oil outlet to cylinder interior oiling, thus piston rod can carry out stop, prevents too much oiling from making piston rod deviate from cylinder body.
This utility model uses the welding of integrated balanced valve, it is not necessary to valve seat and valve partial installation, improves work efficiency, reduces production cost.
The beneficial effects of the utility model are: improve the presentation quality of oil cylinder; improve the wearability of cylinder bearing; also make bearing pin effectively be lubricated and protect simultaneously, extend the life-span of bearing pin, improve work efficiency, reduction production cost, can well prevent piston rod from deviating from from cylinder interior.
