The hydraulic piston rod is a connecting component that supports the work of the piston. Most of them are used in the cylinder and cylinder movement executing parts, and are a moving part with frequent movement and high technical requirements. In order to effectively ensure the coaxiality tolerance of the parts and the mutual positional accuracy of each part, all the machining processes can be positioned with two center holes, and the bucket elevator conforms to the principle of standardization.
In order to ensure the machining accuracy, the hydraulic piston rod should separate the roughing and finishing vehicles when turning the piston rod. Moreover, the coarse and fine cars are always used with the tool holder to reduce the deformation of the workpiece during machining, and the center frame should be remembered when machining the threads at both ends. The center hole should be repaired during processing to ensure the cleanness of the center hole and the tightness between the center hole and the tip, and to ensure good lubrication.
When the hydraulic piston rod is used for guiding assembly, it should be positioned with its outer sealing surface. If the length of the positioning surface is smaller than the matching length of the thread, the thread should first enter the fitting during assembly and then enter the fitting from the positioning surface.
Hydraulic piston rod plating
It refers to the chrome plating on the surface of the worn piston rod. The advantage is that the maintenance technology is simple, the cost is low, the production efficiency is high, the surface finish is good, and it is suitable for batch processing. The surface of the piston rod is subjected to wear-resistance and corrosion-resistant re-manufacturing treatment using a laser. The advantages are high deposition efficiency, smooth surface and long service life of the workpiece.www.xhychromerod.com
