Abstract
The invention relates to a hydraulic cylinder with a buffering function. The hydraulic cylinder with the buffering function comprises a cylinder body, and both ends of the cylinder body are provided with a cylinder cover and a cylinder bottom respectively in a sealed mode; the inside of the cylinder cover is coaxially and slidingly provided with a piston rod in a penetrating mode, and one end of the piston rod is fixedly provided with a piston; both end walls of the cylinder body are provided with an oil inlet and an oil outlet respectively. The hydraulic cylinder with the buffering function is characterized in that one end portion of the piston, which corresponds to the cylinder bottom, is fixedly provided with an elastic member. The hydraulic cylinder effectively buffer the impact force of the piston onto the cylinder bottom through an elastic rubber cushion fixedly mounted on the end surface of the piston, and meanwhile, is simple in structure and low in cost. The hydraulic cylinder with the buffering function is simple in structure, easy to implement and scientific and reasonable in design, and can achieve good buffering effects without increasing existing costs.
Description
Technical field
The invention belongs to oil hydraulic cylinder technical field, specifically, is a kind of oil hydraulic cylinder with pooling feature.
Background technique
In engineering machinery transmission, oil hydraulic cylinder plays a part very large as the actuator of action.In a part of situation, what oil hydraulic cylinder rose is buffer function.Such as in pipelining, workpiece transfers to from a upper station mechanism that next station needs a buffering, especially fast in speed, weight is large, comes impact force successful, stable action that buffer device advances effective with oil cylinder.The oil cylinder of current hydraulic damping circuit can not keep condensing after returning, and has the trend of play forward, or complex structure is not easy to control.
Traditional buffer structure generally adopts one-way valve, and cushioning effect is better, but cost is high.
By retrieval, find following patent publication us related with the present patent application, publication number is CN201636127U, the document discloses a kind of buffering structure of hydraulic cylinder, comprise piston rod, suit piston on the piston rod, the cylinder bottom with oil transportation hole being positioned at the cylinder body outside piston and being connected with cylinder body, it is characterized in that: described cylinder bottom and cylinder body connecting end are provided with valve block locknut, buffering valve block is provided with between valve block locknut and cylinder bottom, valve block locknut and buffering valve block are equipped with center hole, and the center line of center hole overlaps with the center line in oil transportation hole.
By contrast, above-mentioned patent publication us and present patent application have relatively big difference in technological scheme.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the oil hydraulic cylinder with pooling feature that a kind of structure is simple, good buffer effect, cost are low is provided.
Technical solution of the present invention is achieved in that
A kind of oil hydraulic cylinder with pooling feature, comprise cylinder body, cylinder body two ends are sealed and installed with cylinder cap and cylinder bottom respectively, in cylinder cap, coaxial slip installs a piston rod, one end of this piston rod is fixed with piston, cylinder body end walls is separately installed with filler opening and oil outlet, it is characterized in that: the pistons end at the bottom of described respective cylinder is fixedly mounted with an elastomer.
And described elasticity rubber position one resilient rubbber cushion, its thickness is 3-5 millimeter.
And the interior edge face of described cylinder bottom is fixedly mounted with a resilient rubbber cushion, its thickness is 3-5 millimeter.
And the outer rim interval of described piston is shaped with the annular groove that three are placed O RunddichtringO, and electroplate a layers of copper in the outer rim of piston, the thickness of this layers of copper is 0.3mm.
And, the sealing configuration of described cylinder cap and cylinder body is: described cylinder cap is a cylindrical sleeve body structure, and be coaxially arranged in cylinder body, this cylinder cap one end and cylinder body are coaxially installed with seal ring, between this cylindrical sleeve and piston rod, co-axial seal installs a seal ring, and this cylinder cap outboard end and piston rod coaxially install a dust-proof cushion.
Advantage of the present invention and good effect are:
This oil hydraulic cylinder, by being fixedly mounted with one deck resilient rubbber cushion at the end face of piston, effectively can collide the impact force of cylinder bottom by damper piston, and structure is simple, with low cost.The present invention is simple for structure, and design science is reasonable, under increase has the prerequisite of ready-made, has good cushioning effect.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present invention.
Embodiment
