基于PLC的C650立式機床電氣系統(tǒng)的設計
摘 要
車床是廣泛應用的一種技術成熟的切削機床，C650車床是一種中型車床，可用于加工回轉(zhuǎn)直徑1020mm以內(nèi),長度3000mm以內(nèi)的工件。是車床中極具代表性的一種設備。
此次設計是對C650車床傳統(tǒng)電氣控制系統(tǒng)的改進設計和模擬，運用可編譯邏輯控制器實現(xiàn)各種控制、自鎖、聯(lián)鎖、報警功能，優(yōu)化控制系統(tǒng)的性能，提高穩(wěn)定性，降低故障率。
主電機的電氣設計是整個機床電氣設計的重點。主電機的主回路要求帶有正反轉(zhuǎn)、Y-Δ轉(zhuǎn)換、帶限流電阻電氣反接制動。系統(tǒng)要求設計欠壓飽和和過流保護。在模擬樣機中通過電位器經(jīng)AD擴展模塊模擬。
本次設計是一個完整的電氣控制系統(tǒng)，涵蓋了電機的計算、元件的選型、控制方案的設計、圖紙的繪制、電氣主回路的設計，配電系統(tǒng)接線、調(diào)試，是專業(yè)知識的一次總結和實踐。

Abstract
The lathe is one of the most widely used metal cutting lathe, C650 lathe is a medium-sized lathe, the diameter of workpiece up to 1020mm, length up to 3000mm. It is a kind of equipment which is widely used.
Lathe work when the most basic of two kinds of sports: Chuck axle drives the workpiece rotation, called main movement (cutting movement), second is slide carriage thimble drives the cutter to the linear motion, known as a feed movement. The two movements are carried out at the same time. In order to ensure the synchronization between the two, the two movements are driven by the same motor (the main motor), but have their own transmission. Through the respective transmission adjustment to adjust the different spindle speed and feed speed, you can process a variety of different needs of the workpiece.
Cooling pump is also an indispensable equipment of the machine tool. After starting the machine, cooling pump started running, the cooling liquid spray to work cutting noodles, to play to the role of cooling the workpiece, the cutter protection.
The design of the traditional C650 lathe electrical control system to improve the design and simulation, using compiled logic controller to achieve a variety of control, self-locking, interlocking, alarm function, the optimization of the performance of the control system, improve the stability, reduce the failure rate.
The electrical design of the main motor is the key point of the whole machine tool electrical design. The main circuit of the main motor is a kind of positive inversion and Y- delta conversion, with current limiting resistance of electric braking of complex loop.
This design is a complete electrical control system, covering motor calculation, component selection, control scheme design and drawings of the drawing, the main electrical circuit design, distribution system wiring and debugging, which is extensively involved in knowledge is a summary and practice of professional knowledge.
Key words: lathe; power distribution; Programmable Logic Controller;ladder diagram
