In addition, in this special plane included in the overall design of the electrical part of the schematic diagram. In ordinary machine tool, the majority is controlled by the relay contactor to achieve its. Electric control circuit is made up of all kinds of contacts of contactor, relay, button, trip switches and other electrical components of control circuit. Electrical control circuit function is the realization of the electric drive system starting, reverse, braking and speed control, the performance of This design mainly through the analysis of the hydraulic drive system, the design of machine tool electrical wiring diagram, then realize the machine tools of various actions. Through the motor model and related data, refer to the relevant manuals, conform to the requirements of the components. To map the electrical schematic diagram.

Throughout the design process need to complete a series of hard work. Designers should first set up the correct design ideas, to master advanced knowledge of science and technology and scientific dialectical way of thinking. At the same time, must adhere to integrate theory with practice, and continuously review and design experience in practice, to the relevant science and technology workers and is engaged in the production practice of the workers in the field of study, development and innovation, in order to better finish the mechanical design tasks.

附件第一章液压仿形车床的发展概况和应用

1.1 液压仿形的发展概况

液压传动和气压传动统称为流体传动，是据17世纪帕斯卡提出的液体静压力传动原理发展起来的一门新兴技术，是工农业生产中应用广泛的一门技术。现今，流体传动技术水平的高低已经成为一个国家工业发展水平的重要标志之一。

法国的J.贝松于1578年首次用仿形法加工木制装饰品和螺纹。此后机械仿形机床随之出现，至19世纪得到推广；20世纪初出现了带电气机械随动系统的仿形机床；1923年开始生产电接触仿形铣床；30年代，瑞士、德国和美国等相继生产了液压仿形装置，此装置后来又得到不断改进。为了提高小批量工件的生产率，40年代末，带有液压仿形装置的车床得到推广；到50年代,液压仿形机床增加很快。然而70年代以后,由于电子技术和数字控制机床发展较快，仿形机床逐步减少。
