Abstract

The invention discloses a floating type piston rod air-liquid damping air cylinder which comprises a cover sleeve, a cylinder cover, a first cylinder body, a second cylinder body and a piston rod; the first cylinder body is internally provided with a first piston; the second cylinder body is internally provided with a second piston; a hydraulic oil chamber is formed between the first piston and the second piston; a hydraulic oil damping hole is formed between the first cylinder body and the second cylinder body; the first piston is internally provided with a cavity; the lower end of the first piston is connected with a screwed plug; and a bolt connected with the piston rod is arranged in the cavity in a floating manner. With the adoption of a floating type piston rod technology, the problem that the component processing and assembly cost is high under high precision condition is solved; with the adoption of an air-liquid matching mode which adopts compressed gas to provide a driving force and hydraulic oil to provide a damping force, gentle extension and contraction of the piston rod are ensured; and the floating type piston rod air-liquid damping air cylinder is safe and reliable to use.

Description

technical field [0001] The invention relates to the technical field of cylinders, in particular to a floating piston rod gas-liquid damping cylinder. Background technique [0002] The cylinder is a pneumatic actuator, which uses compressed gas to drive the piston to reciprocate in the cylinder, and then the piston drives the piston rod to drive the load to reciprocate. In some operating environments, the piston rod is required to keep running smoothly during the expansion and contraction process, and the existing cylinder is prone to disturbance to the expansion and contraction of the piston rod due to the pressure difference of the compressed air source, especially during the operation of the piston rod expansion and contraction process, if the cylinder The compressed gas in the body suddenly loses pressure, and the piston rod will quickly reset under the load. This situation is most likely to cause unexpected accidents. Another problem with the existing cylinder is the ass...
