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 [0001] The invention relates to a hydraulic cylinder, in particular to a hydraulic cylinder with buffer function. Background technique [0002] In the hydraulic system, the hydraulic cylinder is often used to drive the mechanism with a certain quality. When the hydraulic cylinder moves to the end of the stroke, it has a large kinetic energy. If the deceleration is not performed, the hydraulic cylinder piston and the cylinder head will have a mechanical collision, resulting in impact and noise. destructive. In order to alleviate and prevent this hazard from happening, it is necessary to set up a buffer device in the cylinder body. However, the existing hydraulic cylinders with buffer devices not only have complex structures and high manufacturing costs, but also require high assembly accuracy. Contents of the invention [0003] The object of the present invention is to solve the problems of the existing buffer hydraulic cylinder with complex structure and ...
