At the same time, numerical control technique is related to the strategic importance of a country and it is one of the important foundation industries to reflect the overall national strength of a country, the level of which is the core signs of measuring the modernization of a countrys manufacturing. The realization of the processing of CNC machine tools and production processes has become the development direction of the manufacturing. Popularizing and using numerical control technology is a strategic task in our mechanical manufacturing industry. NC machine tools, which can produce parts with high repeated precision and manufacture complex shape parts with reliability, need no more time to prepare, have more flexibility to alteration of parts, and clamping apparatuses of NC machine tools are very simple. Consequently, NC machine tools will play an important position in mechanical manufacturing at now and a period of time in the future.The topic is the design of CK6163 vertical feed system. First of all, the solution of transmission will be determined according to the typical technological data and combined with the formulation parameters. Design the main structure of the transmission system, including choice the ball screw and design the structure of the slowdown box, so as to complete the design of mechanical structure of the whole system. Then, choice the stepping motor by calculating, drive the ball screw, which led campaign table. In order to complete the design of feeding system, design the control system of stepping motor based on AT89C51, so that the motor to achieve positive or negative rotating, rapid positive or negative rotating, ensure the control of the transmission system.Key words: CNC machine tools；ball screw；stepping motor；single-chip II目錄摘 要IAbstractII1 緒論11.1 數(shù)控機床的發(fā)展歷史與現(xiàn)狀1 1.2 發(fā)展數(shù)控機床的必要性21.3 數(shù)控機床的結構與特點21.4 數(shù)控機床的發(fā)展方向52 設計任務與方案確定72.1 設計任務72.2 設計技術參數(shù)72.3 總體方案的確定73 機械傳動設計計算83.1 計算內(nèi)容及步驟83.2 滾珠絲杠設計計算83.2.1 切削力的計算83.2.2 滾珠絲杠螺母副的計算和選型83.2.3 滾珠絲杠螺母副的驗算103.3 步進電機的計算與選型123.3.1 步進電機選型123.3.2 傳動比的確定133.3.3 轉動慣量的計算133.3.4 步進電機轉矩校核143.3.5 步進電機性能校核153.4 滾珠絲杠的預緊和消隙164 環(huán)保性與經(jīng)濟性分析174.1 經(jīng)濟性分析174.2 環(huán)保性分析17 結論19參考文獻20致 謝214
