Hydraulic oil cylinder with high buffering performance

Abstract

The invention discloses a hydraulic oil cylinder with high buffering performance, and relates to the technical field of hydraulic oil cylinders. The hydraulic oil cylinder comprises a cylinder body, a piston cavity, an oil cavity, an oil guide mechanism and a dust storage box, the oil cavity is formed in the left side of the cylinder body, the piston cavity is formed in the right side of the cylinder body, the oil guide mechanism is installed in the left side of the piston cavity, the end of the oil guide mechanism communicates with the oil cavity, meanwhile, a piston rod is arranged in the piston cavity, the right side end of the piston rod extends out of the side wall of the cylinder body, a sliding plate is arranged on the right side of a fixing block of the oil guide mechanism, and when the piston rod retracts, the end of the piston rod impacts the sliding plate, the sliding plate extrudes a first connecting rod and a second connecting rod inwards, therefore, a first extension spring and a second extension spring generate elastic restoring force to buffer the impact force, a first buffer spring is arranged on the right side of the piston cavity, when the piston rod stretches out, a piston extrudes the first buffer spring rightwards through a sliding ring, the piston rod is buffered, and the buffer performance of the hydraulic oil cylinder is better.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a hydraulic cylinder with high buffer performance. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion 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; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. Buffers and exhausts are application specific and others are esse...

Problems solved by technology

[0003] Due to the excessive force of the existing hydraulic cylinder during use, when the hydraulic cylinder moves to the stroke end at high speed, the two ends of the piston inside the hydraulic cylinder mechanically collide with the hydraulic cylinder, which not only affects the working performance of the mechanical equipment, but also causes Damage to the hydraulic cylinder and other components of the hydraulic system will reduce the service life of the hydraulic cylinder, resulting in the need to quickly replace the new hydraulic cylinder to work, increasing the cost of work
