Abstract

The invention provides a quick-response pneumatic hydraulic cylinder which comprises an upper cover, a cylinder barrel and a lower cover, and the upper cover, the cylinder barrel and the lower cover are sequentially connected. The quick-response pneumatic hydraulic cylinder further comprises a first sealing assembly which comprises two first guiding rings, a plurality of second guiding rings, a step seal and an AQ seal. The two first guiding rings are arranged at the two ends of the outer wall of a piston correspondingly, the second guiding rings are arranged between the two first guiding rings, the AQ seal is arranged between the first guiding ring close to the upper cover and the corresponding second guiding ring, and the step seal is arranged between the first guiding ring away from the upper cover and the corresponding second guiding ring. According to the quick-response pneumatic hydraulic cylinder provided by the invention, movement flexibility and stability of the piston and a piston rod can be improved, abrasion resistance is good, mutual seepage of internal hydraulic oil and internal high-pressure gas is prevented, and the overall service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of gas-liquid cylinders, in particular to a quick-response gas-liquid cylinder. Background technique [0002] Both chambers of the existing common hydraulic cylinder use hydraulic oil, which cannot be adapted to occasions requiring quick response due to the limitation of the transmission characteristics of the liquid. Two different transmission media are used for hydraulic cylinders, and such hydraulic cylinders are called gas-hydraulic cylinders. The rod chamber of the air-hydraulic cylinder is connected to a high-pressure air source, and the rapid expansion of the gas is used to drive the piston to move at high speed. The rodless chamber of the air-hydraulic cylinder uses hydraulic oil. [0003] The main sealing areas in the gas-hydraulic cylinder are the seal between the ceramic piston rod and the cylinder head, and the seal between the piston and the inner surface of the cylinder barrel. Since the work...
