Description

A kind of oil cylinder
Technical field
The utility model is related to a kind of oil cylinder.
Background technology
Oil cylinder is that hydraulic energy is changed into mechanical energy, straight reciprocating motion is done(Or oscillating motion)Hydraulic pressure perform unit Part.Its simple structure, reliable operation.When being realized moving back and forth with it, deceleration device can be removed from, and without drive gap, Stable movement, therefore be used widely in the hydraulic system of various machineries.Oil cylinder power output and piston effective area and its The pressure difference on both sides is directly proportional;Oil cylinder is substantially by cylinder barrel and cylinder cap, piston and piston rod, sealing device, buffer unit and exhaust Device is constituted.Buffer unit is with exhaust apparatus depending on concrete application occasion, and other devices are then essential.According to conventional oil cylinder Structure type, three types can be classified as:The structure type of the oil cylinder of environmental sanitation refuse vehicle is varied, its sorting technique Have various:Can be divided into straight reciprocating motion formula and gyroscopic pendulum dynamic formula by motion mode;Can be divided into list by by action of hydraulic force situation Action type, double-acting type;Telescopic, the pinion and-rack etc. that can be divided into piston type, plunger type, multi-stage expansion by structure type;Press Installation form can be divided into pull bar, earrings, footing, hinge etc.;Pressing force grade can be divided into 16Mpa, 25Mpa, 31.5Mpa etc..
Existing oil cylinder haves the shortcomings that power output is low.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of power output oil cylinder high.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that:
A kind of oil cylinder, includes outer cylinder body, and the outer cylinder body is internally provided with inner cylinder body, piston rod and piston, described outer Fairlead and flange are provided between cylinder body and inner cylinder body, outlet and oil circuit are provided with the piston rod, on the piston rod Piston is provided with, described piston one end is piston rod installation end, and the other end is bolster installation end, and the piston rod installation end sets Steady nail is equipped with, the bolster installation end is disposed with the small bellmouth and annular groove of outer imperial palace, institute by end to middle part State outer surface of piston and be provided with oil sealing mounting groove and piston seal groove.
Preferably, the piston seal groove is provided with twice, the oil sealing mounting groove be located at twice piston seal groove it Between, further increase the sealing property of piston.
Preferably, the steady nail is provided with more than one.
Preferably, the rounded shape of outlet is set.
Preferably, width of the width of the piston seal groove more than oil sealing mounting groove.
During work, after pressure fluid enters into oil cylinder through cylinder upper end oil inlet, pressure fluid is by the oil in piston rod Road and an outlet point two-way respectively enter outer cylinder body and inner cylinder body, piston is moved downward or is loaded, the pressure fluid of inner cylinder body or Gas is discharged from oil circuit.
The beneficial effects of the utility model are:The oil cylinder increased effectively by being provided with inner cylinder body, piston rod and piston Work area, improves power output, has the advantages that small volume and is easy to processing and manufacturing;By being provided with piston, the piston is set Bellmouth, this allows that bolster is gradually tucked into piston along the guiding of bellmouth, and be finally stuck on annular groove, Accordingly even when piston has certain deformation also not interfere with installation, operating efficiency is improve;The surface of piston sets piston seal Groove, improves the sealing property of piston;In piston rod installation end, steady nail can be set, so can be by stablizing pin come steady Gu the connection between piston and piston rod so that both connection precision are higher.Additionally, piston seal groove is provided with twice, enter One step improves the sealing property of piston.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings, wherein:
Fig. 1 is a kind of structural representation of oil cylinder of the utility model.
