【摘要】：電液伺服系統(tǒng)具有較高的響應(yīng)頻率、較高的功率重量比和扭矩慣量比，在國防中的航行控制領(lǐng)域應(yīng)用廣泛。電液伺服閥是決定電液伺服系統(tǒng)性能的關(guān)鍵元件，由于其精度要求高，制造難度較大，目前只能進行批量批次生產(chǎn)，而制約電液伺服閥批量生產(chǎn)的瓶頸是滑閥配磨工藝�；y配磨效率和質(zhì)量強烈依賴操作人員的技術(shù)水平和經(jīng)驗。配磨工藝過程人為因素影響明顯。 本文通過對配磨工藝過程的深入研究，通過對比現(xiàn)有提高工藝水平的技術(shù)，分析各種技術(shù)的優(yōu)缺點，，提出解決配磨工藝瓶頸的自動配磨技術(shù)，該技術(shù)可以在配磨工藝過程中盡可能的減小人為因素影響。 為驗證該技術(shù)的可行性，本文應(yīng)用該技術(shù)理念設(shè)計了相關(guān)的設(shè)備，創(chuàng)新性的研制了帶有在線磨削量檢測功能的滑動尾座，并使用了壓電陶瓷驅(qū)動的微進給頂尖實現(xiàn)精密進給。該設(shè)備使用單片機做為自動控制的核心，具有磨削量在線測量、數(shù)據(jù)自動處理、狀態(tài)自動判斷、電控微進給等功能。 根據(jù)實際生產(chǎn)環(huán)境的實驗驗證，采用自動配磨技術(shù)而研制的設(shè)備能夠有效的提高配磨精度和效率，為解決閥芯配磨工藝瓶頸，實現(xiàn)電液電液伺服閥批量生產(chǎn)打下了基礎(chǔ)。
[Abstract]:The electro-hydraulic servo system has high response frequency, high power to weight ratio and torque inertia ratio, so it is widely used in the field of navigation control in national defense. Electro-hydraulic servo valve is the key component to determine the performance of electro-hydraulic servo system. Because of its high precision and high manufacturing difficulty, the batch production can only be carried out at present, but the bottleneck of mass production of electro-hydraulic servo valve is the sliding valve matching grinding process. The efficiency and quality of sliding valve grinding strongly depend on the technical level and experience of the operator. The effect of artificial factors in the process of matching mill is obvious. This paper analyzes the advantages and disadvantages of various technologies by comparing the existing techniques to improve the technological level, and puts forward an automatic matching technology to solve the bottleneck of the matching mill process. This technology can reduce the influence of artificial factors as much as possible in the process of matching mill. In order to verify the feasibility of the technology, the related equipment is designed with the concept of this technology, and the sliding tail seat with on-line grinding measurement function is developed, and the micro feed center driven by piezoelectric ceramics is used to realize precision feed. The equipment uses single chip microcomputer as the core of automatic control, and has the functions of on-line measurement of grinding quantity, automatic processing of data, automatic state judgment, electronic control micro-feed and so on. According to the experimental verification of the actual production environment, the equipment developed by adopting the automatic matching grinding technology can effectively improve the precision and efficiency of the matching mill, which lays the foundation for solving the bottleneck of valve core matching grinding process and realizing the batch production of electro-hydraulic servo valve.
