Ordinary vertical lathes can meet the cutting of ordinary end facial and outer circles, but it is not suitable for processing of curved parts. Processing curved parts must be designed and manufactured in accordance with the requirements of the parts, and then uses the workstar to process. Therefore, there is a high production cost. Poor adaptability, long processing cycle and other disadvantages. For the structural characteristics of the vertical lathe, through technical and economic analysis, the full digital DC speed regulation of the main machine transmission system of the machine tool, the left knife frame enters the CNC of the system to the system The content of the transformation and the design and commissioning of the CNC electrical control system has been implemented.
1. The full digital DC speed regulation of the main drive system adopts the British European 590 ~+full digital DC speed regulator. On the basis of retaining the original transmission mechanism, the original hydraulic speed transmission of the machine tool is transformed into a hydraulic level 4 -free speed regulation . The reconstruction content includes the choice of speed regulation scheme and motor, the adjustment of the main transmission drive route, and the design of the DC speed regulator control circuit, the PLC control program;
2. The CNC transformation of the left blade to the system uses the drip bead bar bar to replace the original sliding screw, and semi -closed -loop control. The transformation content includes the choice of the system control method of the servo in the system, and the system mechanical part of the system transformation scheme is determined. Parameter calculation and selection of vice and servo motors;
3. Sinumerik 802D CNC system effectively realizes the linkage control of the X -axis and Z axis of the left blade. The design content of the CNC electrical control system mainly includes the composition and connection of the CNC electrical control system, the design and debugging of the PLC program in the CNC system
