A hydraulic cylinder with cushioning performance

Abstract

The invention discloses a hydraulic oil cylinder with cushioning performance, and relates to the technical field of hydraulic oil cylinders, including a cylinder body, a piston chamber, an oil chamber, an oil guiding mechanism and a dust storage box. Cavity, and the inside of the right side of the cylinder is provided with a piston cavity, wherein the left side of the piston cavity is equipped with an oil guide mechanism, the end of the oil guide mechanism communicates with the oil cavity, and a piston rod is arranged inside the piston cavity. The right end of the piston rod protrudes from the side wall of the cylinder, and a slide plate is set on the right side of the fixed block of the oil guide mechanism. When the piston rod retracts, the end of the piston rod hits the slide plate, and the slide plate squeezes inward. Press connecting rod 1 and connecting rod 2, so stretching spring 1 and stretching spring 2 generate elastic restoring force to buffer the impact force, and the right side of the piston chamber is provided with buffer spring 1, when the piston rod stretches out, the piston passes through The slip ring squeezes the buffer spring one to the right to buffer the piston rod, and the buffer performance of the hydraulic cylinder is better.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a hydraulic cylinder with 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 essential...

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
