Abstract

The 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.

Description

technical field [0001] The invention relates to mechanical processing equipment in the technical field of mechanical engineering, in particular to a constant-pressure, fixed-quantity, full-closed-loop servo hydraulic double-feed mechanism of a numerically controlled vertical cylinder liner honing machine. Background technique [0002] The automobile manufacturing industry is the fastest growing and most promising manufacturing industry in my country at present. The cylinder liner is the heart part of the internal combustion engine. Its inner hole roundness, cylindricity, generatri , not only affect the assembly performance of the engine, but also affect the initial run-in of the engine, the lubrication and air tightness of the friction pair between the piston ring and the cylinder wall; the air leakage, compression ratio, power, fuel consumption, and engine oil consumption of the engine , exhaust smoke, environmental performance, etc. have a great impact. The last process of ...
