数控磨床垂直进给机构、磨头及部分控制电路设计 摘要 CNC grinding machine vertical feed body, cement and some control circuit design Abstract: With the development of grinding technology, machine tool grinding machine is also in possession of a fairly large proportion. Grinding technology and the grinder in the machine manufacturing industry occupies a very important position. Grinding technology has developed rapidly in machining plays a very important role. This article from the Introduction, design, design of vertical feed mechanism, grinding head design, part of the design of electrical control, summarize and thank several parts. CNC grinding machine accuracy and the scope of processing embodied in the mechanical part of the accurate calculation of the structure and optimize the design; control system of automated and efficient system in the NC part of the rationalization of design and the flexible application of single-chip microcomputer. Introduction of the CNC grinder part of the role and status of introduced on the development of a grinder and background, but also introduced the status of grinding technology at home and abroad. The overall design has done a brief introduction, the main feed of the vertical design of institutions and cement a detailed description of some of the electrical control circuit design to the study. Finally, to sum up the design to make a review and manufacturing of CNC machine to make Outlook. Key words: surface grinder,vertical feed body, grinding head, NC 目录 磨床相对于车床、铣床等采用数控系统较晚，是因为它对数控系统的特殊要求。近十几年来，借助CNC技术，磨床上砂轮的连续修整，自动补偿，自动交换砂轮，多工作台，自动传送和装夹工件等操作功能得以实现，数控技术在上逐步普及。型号 转速 电机参数 润滑 方式 冷却方式 轴承 尺寸φA x L 轴端尺寸 功率 (KW) 电压(V) 电流(A) 频率(Hz) 扭距 (Nm) φ B φ C M L1 L2 4SG42 42000 5 350 11 700 1.1 油雾 水 7005CETAP 4 x2 7003CETAP 4 x2 120x237 23 14 14x1.5 22 20 在硬件上，以高性能的16位单片机80C196KC为核心，具体电路设计时应遵循以下主要原则：①必须使硬件电路标准化，并尽可能采用通用的系统结构总线，提高灵活性，以便在需要扩充时，只要增加插件板就能实现。②系统中接口采用可编程器件，简化电路，提高通用性，且各相关器件尽量做到性能匹配。③设计时，由于在系统调试中不易修改硬件结构，应考虑留有充分余量，并进行必要的可靠性设计[15]。 4.
