Abstract
The utility model discloses a buffering oil cylinder which comprises a cylinder body, wherein a front end cover and a rear end cover are arranged at two ends of the cylinder body respectively to form a first sealing space, a piston rod is arranged in the cylinder body, one end of the piston rod is connected with a piston arranged in the cylinder body, the other end of the piston rod penetrates through the front end cover and stretches out of the cylinder body, and one end of the piston is provided with a buffering device. Through adjustment of the length of a spring, a buffering stroke of the piston is controlled, and the buffering speed of the oil cylinder is adjusted through a buffering needle. The requirement for matching accuracy of the piston and the cylinder covers is reduced through arrangement of the buffering device, too large suction force can not be generated when the oil cylinder stretches out, stretching-out speed is stable, and the requirement for machining accuracy of the piston and the cylinder covers is reduced, and production cost is lowered.
Description
Technical field
The utility model relates to the hydraulics field, particularly a kind of cushion cylinder.
Background technique
Oil cylinder is an 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.Its effect is can convert hydraulic pressure to mechanical energy.The input quantity of oil cylinder is the flow and the pressure of fluid, output be point-to-point speed and power.The piston of oil hydraulic cylinder can be converted to hydraulic pressure the mechanical energy of linear reciprocating motion by straight reciprocating motion.Oil cylinder is mainly used in needs the long-time place of supporting weight, and it can still can support weight when removing oil pressure, and safe and reliable.Can be used under water, multiple industry such as electric power, building, machine-building, mine, railroad bridge, shipbuilding.
The oil cylinder of existing structure, improve oil cylinder hydraulic can with the efficient of mechanical energy conversion, require piston in the contact rear end cover, piston rod and rear end cover to be connected quality of fit very accurate because degree of adaptability than higher, makes when piston rod contacts with rear end cover, can produce very big rigid impulse, produce very big suction when piston rod stretches out, cause reduce the working life of workpiece, kinetic friction also can damage seal ring or Sealing for a long time.In addition,, make when producing these accessories because the quality of fit of piston rod and end cap requires height, very high to the requirement on machining accuracy of piston and cylinder cap, improved cost of production.
The model utility content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of cushion cylinder, has avoided the rigid impulse between oil cylinder and the cylinder cap, has increased the working life of workpiece.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of cushion cylinder, comprise cylinder body, the cylinder body two ends are provided with front cover and rear end cover respectively to form first seal space, be provided with piston rod in the cylinder body, one end of the piston rod piston interior with being located at cylinder body is connected, the other end of piston rod passes described front cover and extends to outside the cylinder body, and described piston one end is provided with damping device.
As preferably, damping device described in the utility model comprises the elastic component stamping of easing up, the gentle stamping of described elastic component is enclosed within described piston rod one end successively, and piston-rod end is provided for limiting the jump ring of described buffering compressing tablet, and described buffering compressing tablet and described piston form second seal space.
As preferably, several are set on buffering compressing tablet described in the utility model are used for first oil circuit that second seal space is communicated with first seal space.
As preferably, the first oil circuit diameter described in the utility model is 2～3mm.
As preferably, rear end cover described in the utility model is provided for hydraulic oil and flows out the outer buffering pin of described cylinder body and somely be used for second oil circuit that first seal space is communicated with described buffering pin.
The beneficial effects of the utility model are, can come the cushion stroke of control piston by the length of Regulation spring, regulate the buffer speed of oil cylinder according to the buffering pin, the increase of damping device makes the quality of fit between piston and the cylinder cap is required to reduce, oil cylinder stretches out Shi Buhui and produces excessive suction, the speed of stretching out is steady, has reduced the requirement on machining accuracy of piston and cylinder cap, to reduce production costs.
