Abstract
The utility model relates to a hydraulic cylinder with a buffering mechanism. The hydraulic cylinder comprises a cylinder body (1), an oiling hole (1a) is formed in one side of the cylinder body, end covers (3) are arranged at the two ends of the cylinder body respectively, a piston rod (5) is arranged in an inner cavity of the cylinder body, and the piston rod is provided with a piston (2) in sliding fit with the inner cavity of the cylinder body. The hydraulic cylinder is characterized in that a set of buffering holes (5a) is formed in one end of the piston rod, the buffering holes and the piston rod are parallel in the axial direction, and a set of buffering columns (4) is arranged on the end cover at one end of the cylinder body and are in sliding fit with the corresponding buffering holes (5a). The hydraulic cylinder has the advantages that the structure is simple, buffering effect is good, assembly operation efficiency of assembly staff is improved, and the manufacturing cost is low.
Description
Technical field
The utility model relates to a kind of oil hydraulic cylinder, particularly relates 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 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 problem that the purpose of this utility model is to solve existing buffering hydraulic cylinder complex structure, needs higher assembly precision, and a kind of oil hydraulic cylinder with damping mechanism is provided.
The purpose of this utility model is to be achieved by the following technical programs:
A kind of oil hydraulic cylinder with damping mechanism, comprise cylinder body, cylinder body one side is provided with oil hole, cylinder body two ends are respectively equipped with end cap, are provided with piston rod in inner chamber of cylinder block, and piston rod is provided with the piston being slidably matched with inner chamber of cylinder block, it is characterized in that the piston rod one end in inner chamber of cylinder block is provided with pool of buffer hole, axially being parallel to each other of the axial and piston rod of cushion hole, the end cap of cylinder body one end is provided with pool of buffer post, and each bumper post is slidably matched with corresponding cushion hole respectively.
On the basis of technique scheme, can also there is following further technological scheme.
Described piston rod one end is also provided with one group of flow nipple, in each flow nipple, is equipped with throttle orifice, and 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.
The degree of depth of described cushion hole is greater than the height of bumper post, to avoid bumper post damage.
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.
The beneficial effects of the utility model are simple in structure, good buffer effect, and in having improved the efficiency of assembly crewman's assembly manipulation, also there is advantage cheap for manufacturing cost.
Just accompanying drawings and embodiment further illustrate the utility model below.
