A locking cylinder structure with end-of-stroke cushioning

Abstract

The invention discloses a locking oil cylinder structure buffered at the stroke end, which comprises a hydraulic cylinder body. A squeeze chamber is provided inside the working cylinder body of the hydraulic cylinder body. A back pressure chamber is provided on one side of the working cylinder body. The extruding rod is inserted into the chamber, and the inner wall of the extruding chamber is fixedly equipped with a deceleration mechanism. A set of protection mechanisms are installed on both sides of the top of the working cylinder. A cleaning mechanism is provided on the side of the working cylinder outside the extruding rod. A buffer mechanism is provided on the inner wall of the ballast chamber. The present invention uses oil to flow out from the extrusion groove to reduce the speed of the extrusion rod, reduces the impact force of the extrusion rod, and avoids damage to the cutter; uses the cleaning ring knife to clean the waste on the extrusion rod, and uses The sponge snare scrapes the dust on the surface of the extrusion rod to prevent dust from accumulating on the sealing sleeve, making the device less susceptible to dust intrusion.

Description

technical field [0001] The invention relates to the technical field of oil cylinders, in particular to a locking oil cylinder structure with stroke end buffering. Background technique [0002] Hydraulic control is a control method that uses pressured liquid as a control signal transmission. The control system composed of hydraulic technology is called hydraulic control system. Modern processing and production are gradually approaching full mechanization, so hydraulic technology is inseparable. For example, the existing servo tool post generally chooses the oil cylinder to lock, but the oil cylinder used by the servo tool post currently has a large locking force, and the impact when locking is also large, which is easy to cause damage to the blade. The oil method will lead to a significant reduction in the locking speed of the cylinder, which seriously affects the tool change speed of the servo tool post. Therefore, it is necessary to design a locking cylinder structure with ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a locking cylinder structure with buffering at the end of the stroke to solve the problem that the current cylinder used in the servo tool holder proposed in the above background technology has a large locking force and a large impact when locking, which may easily cause the blade to break. damage, and the slow oil feeding method will lead to a significant reduction in the locking speed of the oil cylinder, which seriously affects the problem of the tool change speed of the servo tool post
