Background technology
Hydraulic cylinder is that hydraulic energy is changed into mechanical energy, does straight reciprocating motion（Or pendulum motion）Hydraulic pressure execute member
Part, its simple in structure, reliable operation are widely used, and existing this hydraulic cylinder is in use, when the fortune that piston rod is driven
When the quality of dynamic component is larger, movement velocity is higher, when piston collides with cylinder cap, larger impact and noise are will produce,
Thus control accuracy can be influenced, can even be caused the accident when serious.For this purpose, it is proposed that a kind of buffering hydraulic cylinder.
Utility model content
The main purpose of the utility model is to provide a kind of buffering hydraulic cylinders, in use, utilizing piston rod band piston
It is moved back and forth in the movable chamber of cylinder body setting, realization converts hydraulic energy to mechanical energy, by being set respectively in the both sides of piston
No.1 buffer board and No. two vibration damper plates are set, piston is can avoid and directly collides with front/rear cover, disappeared using the damping spring of setting
Except the active force of shock, stability is improved, the problems in background technology can be effectively solved.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of buffering hydraulic cylinder, including protecgulum, cylinder body and rear cover, the cylinder body side are equipped with protecgulum, and the cylinder body is another
Side is equipped with rear cover, and the cylinder interior is equipped with movable chamber, and the movable chamber is internally provided with piston, and the piston side is equipped with No.1
Buffer board, the piston and No.1 buffer board are fixedly connected by No.1 damping spring, and the piston other side is fixedly connected with work
Stopper rod, the one end of the piston rod far from piston run through protecgulum and extend to the outside of protecgulum, and the piston rod is movably installed with
No. two vibration damper plates, No. two vibration damper plates are fixedly connected with piston by No. two damping springs.
Further, the protecgulum, which is located at the top of movable chamber side, is connected with oil inlet pipe.
Further, the rear cover, which is located at the top of movable chamber side, is connected with oil exit pipe.
Compared with prior art, the utility model has the advantages that：It is set in cylinder body using piston rod band piston
It is moved back and forth in the movable chamber set, realization converts hydraulic energy to mechanical energy, slow by the way that No.1 is respectively set in the both sides of piston
Punching and No. two vibration damper plates can avoid piston and directly collide with front/rear cover, and shock is eliminated using the damping spring of setting
Active force, the utility model is reasonable for structure and safe and reliable, can effectively eliminate the noise generated when work and impact force, improves
The stability and control accuracy of device.
