Description
Technical field
The present invention relates to oil cylinder and manufacture field, be specifically related to a kind of single-acting spring oil cylinder.
Background technique
Along with the development of Chinese Industrialization process, the development of large-scale assembling manufacturing industry, oil cylinder, as the executive component of power, all plays an important role in all trades and professions, and its feature is exactly: steadily, the advantage such as High power output.Oil cylinder kind general on market is a lot, but in engineering machinery, needs the oil cylinder of a lot of specific function, such as, in the mechanism of chain tensioner and wire rope tensioner, Structure of need relative compact, single-acting spring oil cylinder, but the existence of the not this oil cylinder in market.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of structure simple, easy to use, the feature of the compact High power output single-acting cylinder of existing structure, has also possessed and has stretched out and the single-acting spring oil cylinder of retraction function.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of single-acting spring oil cylinder, main body comprises cylinder barrel and piston rod, piston rod is arranged in cylinder barrel, arranges hydraulic fluid port bottom cylinder barrel, and cylinder barrel top arranges end cover, it is characterized in that: described piston rod is set to hollow shape, and the left side top of piston rod arranges the cushion block of an insertion piston rod, is provided with an extension spring in described piston rod, bottom described cylinder barrel, be provided with a fixing bail, described extension spring one end is connected on cushion block, and the other end is fixed on fixing bail.
One end that described cushion block is positioned at piston rod is provided with inner sleeve, for locating extension spring, more stable.
Be provided with O type circle between described cushion block and piston rod, ensure that and stablize firm performance between cushion block and piston rod.
One end that described extension spring is connected with cushion block is set to taper, and the linkage section of extension spring and fixing bail is set to hook-shaped, is conducive to the fixing of extension spring like this, ensure that rear firm stable installed by extension spring.
Be provided with wear ring between described end cap and piston rod, ensure that cylinder block strength, simultaneously more stable.
The present invention is in use: butter enters in chamber by hydraulic fluid port, make cushion block, piston rod, piston together to left movement under pressure effect, one end because of extension spring is fixed on fixing bail, the other end is fixed on cushion block, therefore at this moment extension spring is stretched, until cushion block encounters the stroke being pushed away object or reach oil cylinder, namely complete one way.When butter stops supply, when namely cavity pressure disappears, cushion block, piston rod, piston can move right under the pulling force of extension spring, until reset, at this moment completes backhaul.
The invention has the beneficial effects as follows: the present invention is novel in design, structure is simple, and oil cylinder is that hydraulic pressure stretches out extension spring retraction, has the compact High power output of mechanism, be mainly used in the position of narrow space, and need the occasion of the large ouput force of single-acting, not only facilitate and use in the confined space, there is single-acting cylinder and the feature of extension spring retraction, make simple, easy to use, market value is high, is convenient to utilization and extention.
Accompanying drawing explanation
Fig. 1 is the retracted mode figure of single-acting spring oil cylinder of the present invention;
Fig. 2 be single-acting spring oil cylinder of the present invention stretch out phase diagram.
Embodiment
