Abstract

The invention relates to a hydraulic cylinder with a buffering mechanism. The hydraulic cylinder comprises a cylinder body (1), an oil injection hole (1a) is arranged on one side of the cylinder body, end caps (3) are arranged at two ends of the cylinder body respectively, a piston rod (5) is arranged in an inner cavity of the cylinder body, and a piston in slidably fit with the inner cavity of the cylinder body is arranged on the piston rod. The hydraulic cylinder is characterized in that a group of buffering holes (5a) are arranged at one end of the piston rod, axial direction of the buffering holes is parallel to that of the piston rod, a group of buffering columns (4) are arranged on the end cap at one end of the cylinder body, and each buffering column (4) is in slidable fit with the corresponding buffering hole (5a). The hydraulic cylinder has the advantages that the hydraulic cylinder is simple in structure, good in buffering effect and low in manufacturing cost, and assembling operation efficiency of assembling personnel is improved.

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 purpose of the present invention is to solve the problems of the existing buffer hydraulic cylinder with complicated structure...
