Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinders, in particular to a high wear-resistant component for a hydraulic cylinder. Background Art

[0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines. 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. The buffer device and the exhaust device depend on the specific application occasions, and other devices are indispensable. The existing patent, patent announcement number CN114909360A, is a wear-resistant piston rod assembly for a hydraulic cylinder, a cylinder body, a piston rod is movably connected in the cylinder body, and an end plate is fixedly installed at one end of the piston rod away from the cylinder body; a cylinder body fixing seat is fixedly installed on the cylinder body, an end plate fixing seat is fixedly installed on the end plate, a guide rod is fixedly installed on the end plate fixing seat, and the guide rod passes through the cylinder body fixing seat; a dust cover is fixedly connected to one end of the cylinder body adjacent to the end plate, and the dust cover is set on the outside of the piston rod, and the dust cover is slidably connected to the guide rod; a pneumatic buffer device, and a pneumatic buffer device is connected to the dust cover. The present invention solves the problem of easy wear of the hydraulic cylinder piston rod by adding a dust cover and a pneumatic buffer device to the hydraulic cylinder piston rod, so that the surface of the piston rod cannot be contaminated with dust particles, thereby solving the problem of easy wear of the hydraulic cylinder piston rod.

[0003] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, it is necessary to perform a cleaning and limiting operation on it, so that in the subsequent use process, it is necessary to perform a buffering and positioning operation on it. If it is inconvenient to perform a limit adjustment operation on it, it will affect the convenience of using the component later. Therefore, we propose a high-wear-resistant component for a hydraulic cylinder to solve the above-mentioned problems. Utility Model Content
