【摘要】：隨著中國制造在世界上的地位不斷深入和穩(wěn)固,大量的機(jī)械加工和產(chǎn)品制造在全國各個(gè)不同的地區(qū)完成。目前除了國有大型企業(yè)外,出現(xiàn)了許多外包型小微企業(yè),他們是大中型加工企業(yè)生產(chǎn)鏈中,利潤最低、耗費(fèi)勞動(dòng)力最多的相關(guān)工序主要解決完成的組成部分。在這些小微企業(yè)中,大量的人力在完成鉆孔、攻絲、去毛刺等鉗工工序內(nèi)容。隨著先進(jìn)制造工藝的出現(xiàn),加工制造利潤的降低,傳統(tǒng)加工制造的小微企業(yè)已經(jīng)很難生存,故本論文針對(duì)當(dāng)前現(xiàn)狀,為小微企業(yè)設(shè)計(jì)一種低成本的加工設(shè)備——經(jīng)濟(jì)型鉆孔攻絲機(jī)的控制系統(tǒng)。本論文以鉆孔、攻絲類手動(dòng)操作設(shè)備為對(duì)象進(jìn)行設(shè)計(jì)和改造,提出面向鉆孔、攻絲機(jī)的運(yùn)動(dòng)控制系統(tǒng)。本文對(duì)基于單片機(jī)、ARM、PC以及PLC等運(yùn)動(dòng)控制系統(tǒng)的研究,最終以基于PLC為載體的運(yùn)動(dòng)控制系統(tǒng)進(jìn)行設(shè)計(jì),對(duì)面向鉆孔攻絲的運(yùn)動(dòng)控制系統(tǒng)進(jìn)行了系統(tǒng)的研究和設(shè)計(jì)。首先本文在文獻(xiàn)閱讀階段查閱了國內(nèi)外相關(guān)技術(shù)的研究狀況,發(fā)現(xiàn)在各行業(yè)中都有關(guān)于運(yùn)動(dòng)控制的技術(shù)描述,但是沒有專門針對(duì)鉆孔攻絲機(jī)進(jìn)行運(yùn)動(dòng)控制的解決方案。其次通過對(duì)現(xiàn)有技術(shù)的研究,在本論文中比選了基于單片機(jī)、ARM、PC等相關(guān)技術(shù)的解決方案。通過對(duì)穩(wěn)定性,開發(fā)成本,開發(fā)難度等因素對(duì)比講述該系統(tǒng)的設(shè)計(jì)過程。闡述了伺服電機(jī)的選型,通過對(duì)被控對(duì)象初步的設(shè)想和計(jì)算,對(duì)控制系統(tǒng)的參數(shù)進(jìn)行了設(shè)計(jì),并選定了伺服系統(tǒng)和伺服電機(jī)。最后通過了硬件系統(tǒng)的確定,設(shè)計(jì)了運(yùn)動(dòng)控制系統(tǒng)的電氣控制系統(tǒng)。以PLC為控制系統(tǒng)核心的設(shè)計(jì)方法,簡化了一般輔助控制電路的線路,使控制系統(tǒng)實(shí)現(xiàn)了模塊化。在完成以上基礎(chǔ)工作后,設(shè)計(jì)了基于PLC的運(yùn)動(dòng)控制系統(tǒng)軟件和對(duì)應(yīng)的人機(jī)界面,使被控對(duì)象圖形化操作,完成了運(yùn)動(dòng)控制系統(tǒng)的需求。通過以上的研究過程,設(shè)計(jì)了鉆孔攻絲機(jī)的運(yùn)動(dòng)功能模塊和操作圖形模塊,并結(jié)合控制軟件形成了一個(gè)完整的PLC運(yùn)動(dòng)控制系統(tǒng)。
[Abstract]:As the status of Chinese manufacture in the world is deepening and steady, a large number of mechanical processing and product manufacturing in different regions of the country completed.At present, there are many outsourced small and micro enterprises in addition to large state-owned enterprises. They are the components of the production chain of large and medium-sized processing enterprises, which have the lowest profit and consume the most labor force.In these micro-enterprises, a lot of manpower in drilling, tapping, deburring and other fitter procedures.With the appearance of advanced manufacturing technology and the decrease of manufacturing profit, it is difficult for small and micro enterprises to survive, so this paper aims at the current situation.The control system of economical drilling and tapping machine is designed for small and micro enterprises.In this paper, the drilling and tapping manual operation equipment is designed and reformed, and the motion control system for drilling and tapping machine is put forward.In this paper, the motion control system based on single chip microcomputer and PLC is studied. Finally, the motion control system based on PLC is designed, and the motion control system for drilling tapping is studied and designed systematically.First of all, in the literature reading stage, this paper looked up the research status of related technology at home and abroad, found that there is a technical description of motion control in every industry, but there is no specific solution for motion control of drill tapping machine.Secondly, through the research of the existing technology, this paper compares the solutions based on SCM / ARMPC and other related technologies.The design process of the system is described by comparing the stability, development cost, development difficulty and other factors.This paper expounds the selection of servo motor, designs the parameters of the control system through the preliminary assumption and calculation of the controlled object, and selects the servo system and servo motor.Finally, the electrical control system of motion control system is designed through the determination of hardware system.The design method of PLC as the core of the control system simplifies the circuit of the general auxiliary control circuit and makes the control system modularized.After completing the above basic work, the software of motion control system based on PLC and the corresponding man-machine interface are designed, which make the controlled object operate graphically and fulfill the requirement of the motion control system.Through the above research process, the motion function module and the operation graph module of the drill tapping machine are designed, and a complete PLC motion control system is formed by combining with the control software.
