Description

Technical Field

[0001] The utility model belongs to the technical field of cylinders, and in particular relates to a cylinder buffer device with adjustable buffer pressure. Background Art

[0002] The buffer cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in it. As a type of cylinder, it is mainly composed of a cylinder body, a piston rod, a piston, a buffer plunger, a throttle valve, a one-way valve, an inlet and outlet hole, and an end cover. There are two types of buffer cylinders: non-adjustable buffer cylinders and adjustable buffer cylinders. The former is equipped with a buffer device to slow down the piston when it approaches the end of the stroke to prevent impact, and the buffer effect cannot be adjusted; while the deceleration rate and buffer effect of the latter buffer device can be adjusted. The adjustable buffer cylinder consists of a cylinder body, a piston, and a piston rod. A controllable buffer device is installed inside it to slow down the movement speed of the piston. When the cylinder is working, compressed air enters the cylinder body through the cylinder's air inlet to push the piston outward.

[0003] However, there is friction when the piston rod of the adjustable buffer cylinder reciprocates with the cylinder body. In actual use, lubricating oil is used to improve the operating effect of the piston rod. The operation of manually applying lubricating oil regularly is cumbersome, and the oiling operation is not timely enough to ensure the smooth use of the piston rod. In addition, excessive manual oiling will cause oil dripping during the telescopic movement of the piston rod, and dust accumulates on the surface of the piston rod, which is not easy to clean and will affect the oiling maintenance work.

[0004] Therefore, a cylinder buffer device with adjustable buffer pressure is needed to solve the problem in the prior art that the operation of manually applying lubricating oil regularly is cumbersome and the oiling operation is not timely enough to ensure the smooth use of the piston rod.
