摘 要：數(shù)控鉆孔機(jī)控制系統(tǒng)是用在孔加工機(jī)床上，以可編程序控制器為主控制器，控制鉆頭相對(duì)于工件的定位，由一個(gè)定位點(diǎn)向另一個(gè)定位點(diǎn)的控制系統(tǒng)。該系統(tǒng)由可編程序控制器、步進(jìn)電機(jī)驅(qū)動(dòng)器、步進(jìn)電機(jī)、觸摸屏等構(gòu)成。PLC是專為工業(yè)環(huán)境設(shè)計(jì)的一種工業(yè)控制計(jì)算機(jī)，具有抗干擾能力強(qiáng)、可靠性極強(qiáng)、體積小、編程方便等特點(diǎn)。利用可編程序控制器脈沖輸出指令控制步進(jìn)電機(jī)的轉(zhuǎn)速、方向和移動(dòng)距離，從而實(shí)現(xiàn)精確定位。觸摸屏可用來顯示機(jī)器當(dāng)前運(yùn)行狀態(tài)，保存配方數(shù)據(jù)，還可以設(shè)置運(yùn)行參數(shù)。所設(shè)計(jì)的數(shù)控鉆孔機(jī)控制系統(tǒng)的具有自動(dòng)控制、手動(dòng)控制、運(yùn)行監(jiān)控、參數(shù)設(shè)置等功能。

Abstract：The control system of NC drilling machine which takes the PLC as the main controller is used in drilling machine. It controls the aiguille moving from one positioning to another positioning relative to the positioning of the workpiece. The system consists of PLC, stepper motor driver, stepper motor, HMI, and so on. PLC that designed for the industrial environment specifically is an industrial control computer. It has many advantages, for example, anti-interference capability, high reliability, small size and easy programming and so on. PLC used Pulse Output Function to control the stepper motor speed, direction and distance of movement, accordingly realizing the purpose of exact orientation. HMI can be used to indicate the system’s operating state, to preserv the Filing data, but also can be to set operating parameters. NC drilling machine control system which is designed has automatic control procedures, manual control, operational control, parameter setting, and other functions.
