随着我国工业生产的迅速发展,组合机床、专用机床以及由各种机床组成的自动线等的使用日趋普遍,自动化程度不断提高,从而其电气控制系统越来越复杂。诚然,对于动作简单的机床,无须对其电气原理图加以说明。但是,由于制造、操作和维修上的要求,许多动作复杂的机床,尤其是自动线,其电气原理图的说明是必不可少的。目前的电气原理图说明文字过多,不够简要明了。我们在生产实践中使用了一种电气原理图说明的简明表示方法,下面作一简单介绍。
With the rapid development of industrial production in our country, the use of combination machine tools, special machine tools and automatic lines made up of various machine tools is becoming more and more widespread, and the degree of automation is continuously increasing. As a result, the electrical control system becomes more and more complicated. Admittedly, there is no need to explain the electrical schematic for a simple machine. However, due to the requirements of manufacture, operation and maintenance, the description of the electrical schematic is indispensable for many complicated machine tools, especially for automatic lines. The current schematic diagram shows too much text, not concise enough. We used in the production of a schematic diagram of the electrical schematic that concise method, the following a brief introduction.
