Lateral force resistant oil cylinder

Abstract

The invention relates to a lateral force resistant oil cylinder, and relates to the technical field of mechanical engineering. The lateral force resistant oil cylinder comprises an outer sleeve, a piston assembly and a locking mechanism, the piston assembly is connected in the outer sleeve, and a first oil cavity and a second oil cavity are formed in the piston assembly; the locking mechanism comprises an inner sleeve and a spring bolt, the piston assembly is sleeved with the inner sleeve, one end of the inner sleeve is arranged on the piston assembly in a sliding mode, and a first oil cavity is formed between the inner sleeve and the piston assembly; one end of the spring bolt is connected with the other end of the inner sleeve, a second channel is formed between the spring bolt and the piston assembly, and the other end of the spring bolt is a bearing surface for bearing lateral force; the oil cylinder has an extending state and a retracting state, when the oil cylinder is in the extending state, pressure oil is injected into the second oil cavity and is introduced into the second channel, and the spring bolt is pushed by the pressure oil to move in the direction away from the piston assembly; and in the retraction state, pressure oil is injected into the first oil cavity and is introduced into the first channel, and the inner sleeve is pushed by the pressure oil to drive the spring bolt to move in the direction close to the piston assembly.

Description

technical field [0001] The present application relates to the technical field of mechanical engineering, in particular to an oil cylinder resistant to lateral force. Background technique [0002] At present, the piston and the piston rod of the oil cylinder reciprocate at high speed together, and at the same time, they must bear a large lateral force, which makes the friction between the piston, the piston rod and the cylinder wall and the sealing structure of the oil cylinder intensify, and the external leakage of the hydraulic system increases, resulting in the piston and The radial deformation of the piston rod will affect the service life of the oil cylinder. [0003] In the related technology, measures such as strengthening the sealing of the piston and the guide sleeve, and increasing the wall thickness of the cylinder barrel are used to make the oil cylinder with a common structure have a certain ability to resist lateral force, but it can only resist small lateral fo...

AI Technical Summary

Problems solved by technology

[0004] The embodiment of the present application provides an oil cylinder resistant to lateral force to solve the problem of relying on measures such as strengthening the seal of the piston and guide sleeve and increasing the wall thickness of the cylinder barrel in the related art to make the oil cylinder of ordinary structure have a certain ability to resist lateral force. But it can only resist small lateral force, and has a problem with relatively large limitations
