行星内圆磨床技术改造/TECHNOLOGY REBUILDIGN OF THE PLANET INNER—ROUND GRINDER
Through the technology rebuilding of the planet inner—round grinder, the thesis suggest a method to rebuild the old machine tool by connecting Programmable Logic Controllers with the Variable Voltage Variable Frequency.
As a problem backdrop of the technology rebuilding of the planet inner—round grinder, it adopts the overall logic control of the Programmable Logic Controllers replacing the quondam system, which is against the disadvantages, for instance, the quondam electric control of the grinders adopted the logic control of relays, as well as the high frequency of troubles, the low level of automatism, a poor accuracy, and so on. To meet the needs of the technology and operation of the planet inner—round grinder, it adopts a way to connect the artificial function with the auto one. Also, it adopts variable frequency control function, in case of improving the accuracy of the planet inner—round grinder.
The technology rebuilding improves the accuracy of the planet inner—round grinder and the level of automation. Accordingly, the productivity is improved and the manufacture accuracy is ensured. What’s more, the application of PLC has decreased the frequency of troubles of the machine tool, increased the pliability of the machine tool, as well as decreased the maintenance fare so that a great deal of fund has been saved for the company.
