Analysis of Machining Process of the Hydraulic Cylinder Block with Interference Press Fitting

Abstract

Because the inner hole of the cylinder is matched with the piston, and frequent relative motion is need, so the quality of its processing has great influence on the stability and reliability of the hydraulic cylinder. In this paper the overall process on processing technology of hydraulic cylinder block for pressing fit parts is designed, and its important implementation processes were analyzed, the clamping method and the fixture of inner hole machining are designed. These processes and measures are of significance to the processing of similar products.
