Reliance 57C410D控制擴充模塊現(xiàn)貨

數控機床由輸入、輸出裝置、數控裝置、可編程控制器、伺服系統(tǒng)、檢測反饋裝置和機床主機等組成。
輸入裝置可將不同加工信息傳遞于計算機。在數控機床產生的初期，輸入裝置為穿孔紙帶，現(xiàn)已趨于淘汰;目前，使用鍵盤、磁盤等，大大方便了信息輸入工作。輸出指輸出內部工作參數(含機床正常、理想工作狀態(tài)下的原始參數，故障診斷參數等)，一般在機床剛工作狀態(tài)需輸出這些參數作記錄保存，待工作一段時間后，再將輸出與原始資料作比較、對照，可幫助判斷機床工作是否維持正常。數控裝置是數控機床的核心與主導，完成所有加工數據的處理、計算工作，終實現(xiàn)數控機床各功能的指揮工作。它包含微計算機的電路，各種接口電路、CRT顯示器等硬件及相應的軟件。可編程控制器對主軸單元實現(xiàn)控制，將程序中的轉速指令進行處理而控制主軸轉速;管理刀庫，進行自動刀具交換、選刀方式、刀具累計使用次數、刀具剩余壽命及刀具刃磨次數等管理;控制主軸正反轉和停止、準停、切削液開關、卡盤夾緊松開、機械手取送刀等動作;還對機床外部開關(行程開關、壓力開關、溫控開關等)進行控制;對輸出信號(刀庫、機械手、回轉工作臺等)進行控制。檢測反饋裝置由檢測元件和相應的電路組成，主要是檢測速度和位移，并將信息反饋于數控裝置，實現(xiàn)閉環(huán)控制以保證數控機床加工精度。
數控加工的準備過程較復雜，內容多，含對零件的結構認識、工藝分析、工藝方案的制訂、加工程序編制、選用工裝及使用方法等。機床的調整主要包括刀具命名、調入刀庫、工件安裝、對刀、測量刀位、機床各部位狀態(tài)等多項工作內容。程序調試主要是對程序本身的邏輯問題及其設計合理性進行檢查和調整。試切加工則是對零件加工設計方案進行動態(tài)下的考察，而整個過程均需在前一步實現(xiàn)后的結果評價后再作后一步工作。試切成功后方可對零件進行正式加工，并對加工后的零件進行結果檢測。前三步工作均為待機時間，為提高工作效率，希望待機時間越短越好，越有利于機床合理使用。該項指標直接影響對機床利用率的評價(即機床實動率)。
三、機床數控系統(tǒng)需要解決的幾個問題
機床是由機械和電氣兩部分組成，在設計總體方案時應從機電兩方面來考慮機床各種功能的實施 The motors control the nozzles to swing back and forth. Therefore, the whole etching part is composed of 12 motors. Because the motor keeps swinging back and forth, it is called swing motor here.
1.2 introduction to swing motor movement according to the process requirements, the motor must operate according to a certain trajectory, and different motor operation trajectories are different. Due to the high requirements for the running curve, the B & R PCC and acopos servo controller are selected for the control of the swing motor. On the upper computer, the staff gives 16 points on a track, as shown in Fig. 2, where the horizontal axis is the position and the vertical axis is the speed. Each of the 12 Motors has a set curve. In addition to completing the logic control of starting, stopping and running of the motor, the main function of PCC is to control the motor to move according to a certain trajectory, so that the trajectory passes through the set 16 points at the same time, and ensure the smooth operation of the motor. Due to the requirement of fast response and high control accuracy, the swing part uses synchronous servo motor for motion control. Before using the PLC of Toshiba company, there was a problem of uneven swing, so the high-performance controller PCC developed by B & R was used. PCC uses embedded operating system in the controller, and the device layer network uses real-time Ethernet, which can achieve very high real-time control requirements. The swing part adopts B & R 2005. The 2005 Series CPU is the fourth generation control system SG4 of B & R, and the Intel processor is adopted, including power module, CPU module and digital input / output module. A power link network adapter is inserted into the PCI bus slot of the CPU. If Powerlink is used in series, at most 10 servo controllers can be connected in series. The system uses power link if786 and one hub to divide 12 motors into two series branches for real-time control.
