hydraulic cylinder

Abstract

The invention discloses a hydraulic cylinder, which belongs to the field of mechanical hydraulics. It includes a cylinder body, a piston rod, a bottom cover, a snap ring, a collar and a first connector; the cylinder body is a ring structure with two ends open, the piston rod extends into the cylinder body from one end of the cylinder body, and the other end of the cylinder body A connecting plate is provided; the bottom cover includes a coaxial bottom plate and an annular baffle, the diameter of the bottom plate is equal to the outer diameter of the connecting plate, and the diameter of the annular baffle is equal to the inner diameter of the cylinder body; the first connecting piece is used to connect the bottom plate and the The connecting plate is fixedly connected; the inner diameter of the snap ring is smaller than the outer diameter of the cylinder body, and the inner wall of the snap ring is provided with an annular groove, the diameter of the annular groove is equal to the diameter of the bottom plate, and the axial length of the annular groove is equal to the distance between the bottom plate and the connecting plate The sum of the axial lengths; the collar is used to fit outside the first half ring and the second half ring. The hydraulic cylinder provided by the invention can conveniently and quickly overhaul the mechanical limiter of the piston rod, and can also clean the inside of the cylinder body more thoroughly.

Description

technical field [0001] The invention relates to the field of mechanical hydraulics, in particular to a hydraulic cylinder. Background technique [0002] The hydraulic cylinder belongs to the actuator of hydraulic equipment. It should not only consider the design of cylinder size (inner diameter and length) to meet the transmission force (torque) and piston stroke requirements, but also fully consider the mechanical limit requirements and maintenance convenience. Factors to meet the requirements of the ship. [0003] Present hydraulic cylinder, its cylinder body is the structure that one end is sealed, and one end is open, is provided with piston rod in the cylinder body, and piston rod can move along the axis of cylinder body. There is also a mechanical limit block at the sealing end of the cylinder body, which is used to limit the piston rod and prevent the piston rod from exceeding the limited stroke. When overhauling the mechanical limit block, the piston rod and the se...

AI Technical Summary

Problems solved by technology

[0005] For a hydraulic cylinder with a long axial length, the distance from the open end to the mechanical limit block is relatively long, which will make it difficult to disassemble the mechanical limit block

And when the system oil is polluted and the inside of the cylinder needs to be cleaned, it can only be cleaned from the open end of the cylinder. If the axial length of the cylinder is long, it will easily lead to incomplete cleaning of the inside of the cylinder.
