Hydraulic oil cylinder assembly

Abstract

The invention relates to the technical field of hydraulic oil cylinder application, in particular to a hydraulic oil cylinder assembly. The hydraulic oil cylinder assembly comprises a pipe body, a piston rod, a first connecting pipe, a first cushion, communicating pipes, joints, a piston, a first sealing ring, a second sealing ring, a fixing rod, a first nut, a fixing block, limiting rods, a second cushion, an end cover, a sealing gasket, a third sealing ring, a limiting plate, a dustproof pad, a fixing plate, screw rods, a second nut and a second connecting pipe. The hydraulic oil cylinder assembly is simple in structure and convenient to operate, the buffering capacity is effectively increased during movement of the piston through the design of the cushions, the problem that the piston is damaged due to collision with the pipe body when the piston moves rapidly is avoided, and long-time use of the hydraulic oil cylinder is facilitated; and through the design of the limiting plate, the dustproof pad can be limited and mounted conveniently, dust protection of the connecting position of the piston rod and the end cover is facilitated, dust entering is effectively avoided, and meanwhile fixing of the dustproof pad is facilitated.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil cylinder applications, in particular to a hydraulic oil cylinder assembly. Background technique [0002] Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion or swinging motion. It has a simple structure and reliable operation. When it is used to realize reciprocating motion, the reduction device can be omitted, and there is no transmission gap. It is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; , buffer device and exhaust device. Buffers and exhausts are application specific, other devices are essential. [0003] The current hydraulic cylinder is a hydraulic component that uses the pressurization of hydraulic oil to realize the movement of the...

AI Technical Summary

Problems solved by technology

[0003] The current hydraulic cylinder is a hydraulic component that uses the pressurization of hydraulic oil to realize the movement of the piston rod. However, for the hydraulic cylinder assembly, the collision between the piston and the pipe body may occur due to the excessive speed of the hydraulic cylinder during movement. The problem of piston damage is not conducive to the long-term use of the hydraulic cylinder; and the end cover of the hydraulic cylinder is not conducive to installation. The connection between the end cover and the piston rod may easily contaminate the hydraulic oil due to the entry of dust, which reduces the hydraulic cylinder. The service life is long, and it is not conducive to the installation of the dust pad during installation, causing inconvenience in operation
