Abstract

The invention relates to a hydraulic actuating cylinder realizing buffering at the stroke initial end and relates to the technical field of fluid drive. According to the hydraulic actuating cylinder,a buffering function of the hydraulic actuating cylinder at the initial end of working stroke is realized by a constructed novel internal buffering structure, and the problem that buffering of the initial end of the actuating cylinder is difficult to realize by a traditional internal buffering structure can be solved; and compared with an external buffering mode of the actuating cylinder, the hydraulic actuating cylinder has the advantages of being simple in structure, convenient to mount and maintain, low in use cost and the like.

Description

technical field [0001] The invention relates to the technical field of fluid transmission, and relates to a reciprocating linear motion actuator in a hydraulic system, in particular to a hydraulic cylinder for buffering at the beginning of a stroke. Background technique [0002] The hydraulic actuator is an important reciprocating actuator in the hydraulic system, and its actuation performance has an important impact on the system. When the movement speed of the hydraulic actuator is fast or the load inertia is large, it is easy to produce an impact at the beginning or end of the working stroke of the actuator. Among them, the impact at the initial end of the working stroke mainly acts on the load through the piston rod of the actuator, causing the load to receive a large impact load instantaneously, resulting in vibration and noise, and even motion instability. The impact at the end of the working stroke is mainly caused by the rigid impact of the piston of the actuator on...
