Stepper motor is a pulse signal will be transferred into the angular displacement of the electromechanical DAC device. Its working principle is: each to a pulse will be generated in the stator circuit in a certain space rotating magnetic field。關(guān)鍵詞：XY數(shù)控工作臺(tái)；設(shè)計(jì)任務(wù)；機(jī)械傳動(dòng)部件；控制系統(tǒng)CNC XY table designAbstractThe design is in the NC machine tool works on top of design a simple, economical CNC xy table. XY table CNC electromechanical system design is an openloop control system, its structure is simple, convenient and can guarantee to achieve a certain degree of accuracy. Reduce costs, is a putercontrolled technology, the simplest applications. It is full advantage of the crisis in software and hardware capabilities in order to achieve the control of machine tools。其工作原理是：每給一個(gè)脈沖便在定子電路中產(chǎn)生一定的空間旋轉(zhuǎn)磁場；由于步進(jìn)電機(jī)通的是三相交流電，所以輸入的脈沖數(shù)目及時(shí)間間隔不同，轉(zhuǎn)子的旋轉(zhuǎn)快慢及旋轉(zhuǎn)時(shí)間的長短也是不同的。本設(shè)計(jì)的經(jīng)濟(jì)型數(shù)控工作臺(tái)精度并不高，采用開環(huán)系統(tǒng)；機(jī)械傳動(dòng)部分采用步進(jìn)電機(jī)直接連接滾珠絲杠，從而驅(qū)動(dòng)工作臺(tái)進(jìn)給。設(shè)計(jì)任務(wù)是完全圍繞數(shù)控機(jī)床工作原理而展開的，本設(shè)計(jì)充分體現(xiàn)了數(shù)控機(jī)床機(jī)械設(shè)備部分與電氣設(shè)備部分的緊密結(jié)合。降低成本,是微機(jī)控制技術(shù)的最簡單的應(yīng)用。茂名職業(yè)技術(shù)學(xué)院 畢 業(yè) 設(shè) 計(jì)茂名職業(yè)技術(shù)學(xué)院2011年12月21日數(shù)控銑床XY工作臺(tái)設(shè)計(jì)【摘要】本設(shè)計(jì)是在數(shù)控機(jī)床工作原理之上設(shè)計(jì)一臺(tái)簡單的、經(jīng)濟(jì)型的xy數(shù)控銑床工作臺(tái)。XY數(shù)控工作臺(tái)的機(jī)電系統(tǒng)設(shè)計(jì)是一個(gè)開環(huán)控制系統(tǒng),其結(jié)構(gòu)簡單，實(shí)現(xiàn)方便而且能夠保證一定的精度。它充分的利用了微機(jī)的軟件與硬件功能以實(shí)現(xiàn)對(duì)機(jī)床的控制,使機(jī)床的加工范圍擴(kuò)大,精度和可靠性進(jìn)一步得到提高。XY數(shù)控工作臺(tái)設(shè)計(jì)包括總體方案的設(shè)計(jì)、步進(jìn)電機(jī)的選用、傳動(dòng)裝置的設(shè)計(jì)、電氣控制部分的設(shè)計(jì)和相關(guān)軟件的設(shè)計(jì)。步進(jìn)電機(jī)是一個(gè)將脈沖信號(hào)轉(zhuǎn)移成角位移的機(jī)電式數(shù)模轉(zhuǎn)換器裝置。由于旋轉(zhuǎn)磁場對(duì)放入其中的通電導(dǎo)體即轉(zhuǎn)子切割磁力線時(shí)具有力的作用，從實(shí)現(xiàn)了旋轉(zhuǎn)磁場的轉(zhuǎn)動(dòng)迫使轉(zhuǎn)子作相應(yīng)的轉(zhuǎn)動(dòng)，所以轉(zhuǎn)子才可以實(shí)現(xiàn)轉(zhuǎn)子帶動(dòng)絲杠作相應(yīng)的運(yùn)動(dòng)。 to expand the scope of processing machines, precision and reliability, and further enhanced. Design task is pletely around theNC machine tool works and carried out,this design fully reflects the CNC machine tools and electrical equipment, machinery and equipment part of the close bination of parts. CNC XY table design includes the overall program design, selection of stepper motors, gear design, electrical control part of the design and related software design. The design of the economy is not highprecision CNC table, using openloop system。 due to pass the threephase stepper motors AC Therefore, the number of input pulses and the time interval is different from the rotation of the rotor rotation
