Abstract
The invention relates to a hydraulic cylinder with a throttling buffer mechanism. The hydraulic cylinder comprises a cylinder body (1). One side of the cylinder body is provided with an oil filler (1a). A piston rod (5) is arranged in an inner cavity of the cylinder body. The piston rod is provided with a piston (2) in sliding fit with the inner cavity of the cylinder body. Two ends of the cylinder body are provided with end covers (3). The hydraulic cylinder is characterized in that the end cover at one end of the cylinder body is provided with a buffer hole group (4), and the axis of each buffer hole is parallel to the axis of the end cover; one end of the piston rod is provided with a buffer post group (5a), and the buffer posts (5a) are in sliding fit with the corresponding buffer holes (4). The hydraulic cylinder has the advantages that the structure is simple, buffer effect is good, assemblers can assemble more efficiently, and manufacture cost is low.
Description
Technical field
The present invention relates to a kind of oil hydraulic cylinder, particularly relate to a kind of oil hydraulic cylinder with pooling feature.
Background technique
The normal mechanism that uses Driven by Hydraulic Cylinder to have certain mass in hydraulic system, when hydraulic cylinder has larger kinetic energy during to stroke end, slows down and processes as do not done, and mechanical collision will occur for hydraulic cylinder piston and cylinder cap, and generation impact, noise, have destructiveness.For relaxing and preventing that this harm from occurring, and need establish damping device in cylinder body.And the existing oil hydraulic cylinder with damping device not only complex structure, manufacture cost are high, but also need higher assembly precision.
Summary of the invention
The object of the invention is to solve the problem of existing buffering hydraulic cylinder complex structure, assembly precision that needs are higher, and a kind of oil hydraulic cylinder with throttling buffering mechanism is provided.
The object of the invention is to be achieved by the following technical programs:
A kind of oil hydraulic cylinder with throttling buffering mechanism, comprise cylinder body, cylinder body one side is provided with oil hole, in inner chamber of cylinder block, be provided with piston rod, piston rod is provided with the piston being slidably matched with inner chamber of cylinder block, and cylinder body two ends are respectively equipped with end cap, the cylinder cap that it is characterized in that cylinder body one end is provided with pool of buffer hole, each cushion hole axially all with being axially parallel to each other of end cap, described piston rod one end is provided with pool of buffer post, each bumper post is slidably matched with corresponding cushion hole respectively.
The degree of depth of described cushion hole is greater than the height of bumper post, to avoid bumper post damage.
On the basis of technique scheme, can also there is following further technological scheme.
On the cylinder cap of described cylinder body one end, be also provided with one group of flow nipple, in each flow nipple, be equipped with throttle orifice, throttle orifice one end is communicated with by return port with corresponding cushion hole.
Described each bumper post one end is equipped with L-type through hole, and the axis of L-type through hole one end is parallel to the axis of bumper post, and the axis of its other end is perpendicular to the axis of bumper post.
By the bumper post being slidably matched with cushion hole, cushion hole is blocked and progressively compress the hydraulic oil in it, to increase gradually the hydraulic oil pressure in cushion hole, meanwhile, being extruded the active force of stressed hydraulic oil reaction on cushion hole and bumper post also strengthens gradually, and then slow down the movement velocity of piston rod and piston, reduce the impact force of piston to end cap.
Beneficial effect of the present invention is simple in structure, good buffer effect, and when having improved the efficiency of assembly crewman's assembly manipulation, also there is advantage cheap for manufacturing cost.
Below just accompanying drawings and embodiment the present invention is further described.
