Abstract

The invention relates to a stroke-adjustable air cylinder. The stroke-adjustable air cylinder comprises a support, an air cylinder arranged on the support and a hydraulic cylinder arranged on the support; the air cylinder comprises a cylinder body arranged on the support, a first piston movably arranged in the cylinder body and a piston rod in linkage with the first piston, one end of the piston rod extends out of the cylinder body, a second piston is movably arranged at the position, corresponding to the first piston, of the piston rod, and an oil injection adjusting cavity is formed between the first piston and the second piston; and an oil guide pipe is arranged between the cylinder body and the hydraulic cylinder, a spiral oil guide pipe communicating between the oil guide pipe and the second piston is arranged in the cylinder body, and the second piston is provided with an oil injection hole communicating between the spiral oil guide pipe and the oil injection adjusting cavity. The stroke-adjustable air cylinder has the advantages of being simple in structure, stable and reliable in performance, convenient to assemble and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of cylinders, in particular to a cylinder with adjustable stroke. Background technique [0002] The cylinder is a pneumatic actuator, which uses compressed air as power, and the drive mechanism performs linear, oscillating and rotating motions. The cylinder is composed of a cylinder barrel, an end cover, a piston, a piston rod and a seal. The movement of the piston of the existing cylinder is full stroke, the stroke of the piston and the piston rod cannot be adjusted, the stroke of the cylinder is uncontrollable, and its applicable occasions are very limited. Therefore, it is very necessary to design a cylinder with adjustable stroke. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide an adjustable stroke cylinder with simple structure, stable and reliable performance, convenient assembly and convenient operation. [0004] In or...
