TLDR: In this article, a servo-hydraulic double-feeding mechanism for a numerical control vertical cylinder sleeve honing machine is presented, which includes an inner push rod and an outer push rod positioned at the middle part of a hollow stroke main shaft.

Abstract: The present invention discloses a servo-hydraulic double-feeding mechanism for a numerical control vertical cylinder sleeve honing machine, which comprises an inner push rod and an outer push rod positioned at the middle part of a hollow stroke main shaft, wherein the inner push rod is positioned in the outer push rod; the outer push rod is driven by a servo feeding closed-loop control mechanism to move up and down; the inner push rod is driven by a hydraulic feeding closed-loop control mechanism to move up and down; and a programmable digital control system is connected with sensors in the a servo feeding closed-loop control mechanism and the hydraulic feeding closed-loop control mechanism to realize straight line-driven closed-loop feedback and hydraulically-driven closed-loop feedback, and is arranged outside an integrated safety protector of a machine tool. The servo-hydraulic double-feeding mechanism has the advantages of simple structure, rational layout, excellent working stability and reliability, high machining precision, a visual operating interface and the capacity of realizing the high-quality machining of a flat reticulate pattern for a cylinder (sleeve) internal hole of an internal combustion engine.
