Abstract

The invention discloses a hydraulic buffer device, and belongs to the technical field of hydraulic transmission. The hydraulic buffer device comprises a main block body and a buffer assembly, a hydraulic channel and a control channel are formed in the main block body, the two ends of the hydraulic channel penetrate through the main block body, and the control channel communicates with the hydraulic channel. The buffer assembly comprises a connecting block, a piston, a piston rod and an elastic piece, the connecting block is located on the main block body, a buffer cavity is formed in one sideof the connecting block and communicates with the control channel, the piston coaxially sleeves the first end of the piston rod, and the hydraulic channel communicates with a hydraulic cavity througha first flow channel. The outer circumferential wall of the second end of the piston rod is in sliding fit with the inner circumferential wall of the control channel to control the opening degree of the hydraulic channel, and the elastic piece is located in an elastic cavity. The hydraulic buffer device can prevent hydraulic pressure from generating instantaneous impact on execution elements, so that the service life of the execution elements is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of hydraulic transmission, and more specifically relates to a hydraulic buffer device. Background technique

[0002] Hydraulic transmission refers to a transmission method that uses liquid as the working medium for energy transmission and control, specifically the use of liquid pressure for energy conversion. The use of hydraulic transmission technology in machinery can effectively simplify the structure of the machinery, reduce the weight of the machinery, reduce material consumption, reduce manufacturing costs, reduce labor intensity, and improve work efficiency and reliability.

[0003] Nowadays, hydraulic transmission technology is widely used in various mechanical products, but in the process of high-pressure liquid transmitting energy to the actuator, it will cause a large instantaneous impact on the actuator, which will not only bring greater noise, but also affect the service life of actuators.
