Hydraulic oil cylinder capable of effectively preventing fatigue fracture

Abstract

The invention discloses a hydraulic oil cylinder capable of effectively preventing fatigue fracture. The hydraulic oil cylinder comprises a left end cover, a hydraulic oil cylinder body and a right end cover, the hydraulic oil cylinder body is fixedly installed in the middle of the inner side of the left end cover, the right end of the hydraulic oil cylinder body is fixedly installed on the left side of the right end cover, and the right end of a movable column is installed on the right end cover; the movable column and a movable rod are connected through a built-in spring, an adjusting arc-shaped plate is installed at the right end of a connecting cover, a lateral rod is fixedly installed on the inner side of the adjusting arc-shaped plate, the outer end of a clamping column is fixedly installed on the inner side of the connecting cover, and the clamping column and a roller rod are connected through a reset spring. According to the hydraulic oil cylinder capable of effectively preventing fatigue fracture, a good damping protection effect can be achieved, the possibility of fatigue fracture caused by too large loading force of the hydraulic oil cylinder is reduced, meanwhile, a certain dustproof protection effect can be achieved, and dust is prevented from entering the interior of the hydraulic oil cylinder.

Description

technical field [0001] The invention relates to the related technical field of hydraulic cylinders, in particular to a hydraulic cylinder which can effectively prevent fatigue fracture. Background technique [0002] With the development of society, the machinery industry is also making continuous progress. Hydraulic cylinders are commonly used components in the machinery industry. Common structural forms can be divided into several categories such as piston type, plunger type, telescopic type and swing type. Hydraulic cylinders It is the actuator in the hydraulic transmission system, and the hydraulic energy can be effectively converted into mechanical energy through the hydraulic cylinder. [0003] However, the existing hydraulic cylinders have the following problems: [0004] 1. The existing hydraulic cylinder itself is inconvenient to play a good shock-absorbing and protective effect when it is in use, so that when the piston rod of the hydraulic cylinder is reciprocatin...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a hydraulic cylinder that can effectively prevent fatigue fracture, to solve the problem that the existing hydraulic cylinder itself is not convenient to play a good shock absorption and protection function in use in the above background technology, which leads to the failure of the hydraulic cylinder when it is used. When the piston rod is reciprocating, it often suffers from fatigue fracture due to its own excessive load force. It is not convenient to play a certain role in dust protection during the working process. Afterwards, it is easy to cause dust to enter the interior, which reduces the practicality of the hydraulic cylinder itself.
