Technical field
The utility model is related to technical field of hydraulic oil cylinder, especially a kind of piston hydraulic cylinder.
Background technology
Hydraulic cylinder be hydraulic energy is changed into mechanical energy, the hydraulic pressure that does straight reciprocating motion (or oscillating motion) performs member
Part.Its simple in construction, reliable operation.Realized with it during reciprocating motion, deceleration device can be removed from, and without drive gap,
Stable movement, therefore be used widely in various mechanical hydraulic systems.The coefficient of friction of existing piston hydraulic cylinder
Height, lubricant effect is poor, easily causes the serious wear of piston and cylinder body, it is necessary to often change, while being installed on existing piston rod
Typically all threadedly fix, but when piston carry out demolition and replacement, make when the piston of its end head is being fixed
It is inconvenient into dismounting, waste time and energy, reduce operating efficiency.
Utility model content
The technical problems to be solved in the utility model is：Deficiency in the prior art is overcome there is provided a kind of high lubricating effect,
Coefficient of friction is reduced, good seal performance is convenient, fast when changing, dismantle and repairing, and improves the double-piston hydraulic of operating efficiency
Cylinder.
The utility model solves the technical scheme that its technical problem used：A kind of piston hydraulic cylinder, with cylinder body,
The gland coordinated with the cylinder body and piston rod, left piston and right piston in the inner chamber of cylinder block, it is described
The outer surface left and right ends of cylinder body are equipped with oil inlet pipe, and upper cover of piston rod is provided with left piston, and its right-hand member is fixed by fixing device
There is right piston, the outer surface of the left piston is provided with some round section joint rings, and the inner surface of left piston is provided with " u "-shaped circle, described
The both ends of the outer surface of right piston are provided with " u "-shaped sealing ring；
The fixing device includes opens up fluted on shaft block ring and card key, the piston rod at right piston,
Card key for fixing right piston is installed, card key is provided with shaft block ring in groove.
Further, described left piston is made of ductile cast iron material, and right piston is made of 45 steel.
Further, polytetrafluoroethylene (PTFE) new material wearing layer is coated with the outer surface of the right piston.
Further, there are carbide layers by supersonic spray coating on the outer surface of described piston rod.
The beneficial effects of the utility model are：It is of the present utility model simple in construction, easy to use, high lubricating effect, reduction
Coefficient of friction, good seal performance, and meanwhile it is convenient, fast when changing, dismantle and repairing, operating efficiency is improved, time saving and energy saving, warp
Ji property is good, and service life is long.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
1. left piston in figure, 2. right pistons, 3. piston rods, 4. glands, 5. " u "-shaped circles, 6. " u "-shaped sealing rings, 7. " O " shapes
Circle, 8. cylinder bodies, 9. oil inlet pipes, 10. shaft block rings, 11. card keys, 12. grooves.
Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of piston hydraulic cylinder as shown in Figure 1, the gland 4 coordinated with cylinder body 8, with the cylinder body 8 and installation
