Abstract

An optimization method for a servo valve core working edge small burr online removal process system comprises the steps: (1) performing grinding simulation on the end face of a valve core by finite element software, measuring the height and width of generated burrs, and carrying out optimization on actual processing parameters; (2) carrying out a grinding experiment on the end face of the valve core, measuring the height and width of the generated burrs, and comparing with simulation results to obtain a relevant change rule between the sizes of the burrs and the actual processing parameters; (3) carrying out a working edge small burr removal experiment by using a turning way, and measuring the turning force in the process; (4) constructing an optimized process system and specific process parameters thereof according to the sizes of the burrs obtained in the steps (1) and (2) and the turning force in the step (4); (5) carrying out working edge small burr online removal on the optimized process system. By adopting the optimization method, the burr online removal process system is optimized, the production efficiency is improved, the part scrap rate is reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to the construction of a processing system for a servo valve, in particular to an optimization method for an online removal process system of tiny burrs on the working side of a valve core of a servo valve, and belongs to the technical field of mechanical manufacturing. Background technique [0002] The spool is the central shaft part of the core component of the power amplifier stage of the servo valve, the pair of spool valves, and the axial matching accuracy between its working side and the throttling window of the valve sleeve directly determines the working performance of the servo valve. During the production process, the final processing process of the working side adopts the grinding method of precision grinding machines, and tiny burrs will be generated during the processing process, which has an important impact on the performance of the pairing movement flexibility and the amount of superposition. [0003] At present, r...
