Brief description of the drawings
Fig. 1：Structural representation of the present utility model.
Embodiment
Specifically describe a kind of buffer type hydraulic oil cylinder with reference to embodiments, with reference to shown in Fig. 1, including cylinder tube 6 and
The piston 2 being arranged in cylinder tube cavity, the front end of piston 2 are connected with a cylinder rod 3, the distal end extension of the cylinder rod 3
Go out cylinder tube to be connected with oil cylinder head 4, buffering cone 5 is provided with the cylinder rod 3.51 diameters of the buffering cone distal end are less than
The buffering cone diameter of near-end 52.
Have the function that buffering to preferably coordinate with the buffering cone 5, the cylinder tube front end is and the oil cylinder
The cushion chamber 7 of cylinder cavity UNICOM, the internal diameter of cushion chamber 7 are less than the cylinder tube cavity inside diameter.The buffering cone near-end 52 is straight
Footpath is suitable with the internal diameter of cushion chamber 7.The distance of buffer bar 31 is provided between the buffering cone 5 and the piston 2.And the buffering
The length of bar 31 is more than the length of the cushion chamber 7.For buffering cone 5 in motion, buffering cone near-end 52 reaches cylinder tube distalmost end
When, due to the presence of buffer bar 31 so that piston can't directly be collided with cylinder tube, so as to avoid destruction sexual behavior
Therefore generation.
Oil inlet 12 and oil-out 11 are provided with the cylinder tube, the oil inlet 12 is arranged on the oil cylinder head of cylinder tube
End 1, the oil-out 11 are arranged on the oil cylinder tail end of cylinder tube, and with the oil cylinder barrel chamber UNICOM.In order to preferably to hydraulic pressure
Oil cylinder carries out the control in speed and direction, and a controlling organization, one end of the controlling organization are also associated with the hydraulic jack
It is connected with cushion chamber, the other end is connected with cylinder tube cavity.What the controlling organization included being arranged in parallel is used for control direction
Check valve 9 and the choke valve 8 for controlling flow.Specifically, the oil inlet 14 of the controlling organization is connected with cushion chamber, control
The oil return opening 13 of mechanism is connected with cylinder tube cavity, and the oil return opening 13 of the controlling organization and the oil-out on the cylinder tube
11 is coaxial.
Operation principle of the present utility model under set forth below：
Pressure oil is entered by oil inlet 12, promotes piston 2 to move, the pressure oil in cylinder tube is by oil-out 11 with entering
