第9章 装 配 图
9.3 装配图中尺寸标注、零件编号及明细栏的填写
9.3.1 尺寸标注
装配图不同于零件图，不直接用于制造零件，因此不必标注
全部零件的所有尺寸， 只需标注下面几种尺寸即可。 1．特征尺寸
特征尺寸是表示装配体特征或规格的尺寸。如图9-3中的尺寸
按不剖绘制。
(2) 相邻两零件接触在一起(即基本尺寸相同)，规定只画一 条轮廓线。相邻两零件不接触，无论间隙多小，均应留有间隙。
第9章 装 配 图 (3) 对于两相邻零件，当其剖切后，剖面线符号应有所区 别。若两相邻零件为金属材料，则应改变剖面线的方向和间隔 加以区别。 (4) 同一零件在装配图的不同视图中，其剖面线的方向和 间隔应完全一致。当零件厚度较薄时，其剖面线允许涂黑。 图9-2所示的示例综合体现了装配图上的规定画法。
零件图已在第7章作过介绍，本章介绍装配图，第三类图
将在第10章中介绍。
第9章 装 配 图
9.1 装配图的作用和内容
表达整件或部件的图样称为装配图。装配图反映设计者 的意图，表达装配体的工作原理、性能要求、零件之间的装 配关系和零件的主要结构形状，以及在装配、检验、安装时 所需要的尺寸数据和技术要求。在进行设计、装配、调试、
(3) 部件：由材料、零件等以可拆卸或不可拆卸连接所组
成的产品，是在装配比较复杂的产品时必须经过的中间阶段， 如电路板。
(4) 零件何一个电气设备的生产过程必须是：先
制造出零件，然后把零件装配成部件，再把部件和零件装配成 整件，最后根据要求把整件配套成设备。 电气设备既包含机械部分，又包含电气部分，这两部分既 相互独立，又有内在联系。例如，当我们拆开一台计算机主机 机箱时，可以看到机箱内固定着硬盘、光驱、软驱、开关电源 和主板，主板上插接着若干块电路板，电路板上有许多集成电 路、分立元件(电阻、电容等)和接插件，这些属于电气部分，

电气简图的分类
2020/2/8
❖从电气简图图样绘制方法的角度上看，电 气简图有两大类：
▪ 一类是以封闭几何线框为主要符号的电气图； ▪ 另一类则是采用各种电气符号绘制的电气图。
▪ 项目代号中的端子代号标注在端子或端子位置 的旁边。
▪ 对于画有围框的功能单元和结构单元，其项目 代号标注在围框的上方或右方。
▪ 大多数情况，项目代号中的高层代号可以标注 在标题栏内或图纸的上方，简化符号旁项目代 号的标注。

1、建筑电气安装平面图中各电气设备图形符号与电路图 中的符号不尽相同。其图形符号只用来表示该电气设备平 面布置或规划，不用于概略图、电路图等功能图中。 在建筑电气安装平面图上，通常不标注项目代号，一般应 标注了设备的编号、型号、规格、安装和敷设方式等 在建筑电气平面图上需要画出某些建筑构件、构筑物、地 形地貌等图形和位置 。 在建筑平面图上，为突出电气布置，通常电气图线比建筑 图线的宽度大1～2个等级 6、建筑电气平面图是在建筑区域或建筑平面图的基础上 绘制出来的，其图上的位置、图线等应与建筑平面图协调 一致。

1、图样的名称和配置
一套完整的房屋建筑施工图包括总平面图、平面图、 立面图、剖面图和详图等。
房屋建筑图的图示特点
（1）、平面图：假想用一个水平面沿窗台之 上的位置把房屋切开，将上部分移走后向 下进行投影所得到的水平剖视图，称为平 面图。 （2）、立面图：在平行于建筑物立面的投影 面上所作的视图称为立面图。 （有三种命名方式） （3）、剖面图：将建筑物竖直剖切后，向投 影面作投射所得到的视图称为剖面图。

一、设备安装图的识读方法与步骤
右击“布局”标签，使用弹出的快捷菜单中的 命令，可以删除、新建、重命名、移动或复制 布局。
三、布局的页面设置
1. 命令激活方式
命令行：PAGESETUP 菜单栏：文件→页面设置管理器
2. 操作步骤
激活命令后，屏幕弹出 “页面设置管理器”对话框。 单击“页面设置管理器”对话框中的“修改”按钮， 打开 “页面设置”对话框。按照两个对话框的主要 功能进行设置
五、相对图纸空间比例缩放视图
如果布局图中使用了多个浮动视口时，就可以为这些 视口中的视图建立相同的缩放比例。
9.6.2 出图设备的配置管理
一、配置打印机
利用“绘图设备管理器”，在AutoCAD提供了出图设备驱 动程序中，配置绘图设备。 在创建布局时，需要指定绘图仪和设置（例如图纸尺寸和打 印方向），这些设置将保存在页面设置中，与不同的布局相 关联。

本章引言：
由于电气技术的广泛运用，各种电气工程越来越 多，电力安装图已成为电气工程图中的重要组成 部分。本章将介绍几种常用的建筑电力安装图、 设备安装图、电力线路安装图，从这几种图样中， 我们不难看到电气图与建筑图、机械图等交叉运 用的特点。

(4)详图：用较大比例详细表示建筑细部结构的图
样。详图可以用视图、剖面图、断面图等表示。
建筑制图的有关规定
2、比例：按下表选取
3、图线
4、尺寸
单位：标高以米为单位，其余以毫米为单位。 平面图中：第一道尺寸为房屋的总长和总宽；
第二道尺寸为墙、柱轴线间的尺寸；第三道 尺寸为门窗洞宽度和位置的尺寸。
方法：识读设备安装图的方法与识读机械图 类似
1、看标题栏，进行概括了解。 2、分析视图，了解表达方法及其作用。 3、分析安装设备的厂房。 4、分析各设备的安装位置及连通情况 5、进行总结，全面了解设备安装图。

四、使用布局视口
要在布局中显示和缩放模型空间的视图，需创 建布局视口。
在构造布局图时，可以将浮动视口视为图纸空间的图形对象，并 对其进行移动和调整。浮动视口可以相互重叠或分离。在图纸空间中 无法编辑模型空间中的对象，如果要编辑模型，必须激活浮动视口， 进入浮动模型空间。激活浮动视口的方法有多种，如可执行MSPACE命 令、单击状态栏上的“图纸”按钮或双击浮动视口区域中的任意位置。 删除、新建和调整浮动视口 相对图纸空间比例缩放视图 在浮动视口中旋转视图 创立特殊形状的浮动视口
9.1.2 建筑施工图的识图
阅读建筑施工图时应通过阅读首页图先对建筑 物有一个概况了解，再按目录顺序（按“建 施”、“结施”、“设施”的顺序）通读一遍， 初步认识该工程对象的建设地点、周围环境、 建筑物的大小及形状、结构型式和建筑关键部 位等。然后，负责不同专业（或工种）的技术 人员，根据不同要求，重点深入地看不同类别 的图纸。阅读时，应先整体后局部，先文字说 明后图样，先图形后尺寸等依次仔细阅读。
9.5.2 绘制建筑电气平面图实例
作图的基本思路：
首先绘制建筑物三定位轴线，确定建筑平面的大致 轮廓，然后绘制墙体、门、窗等，作出建筑物的平 面图，其次按位置布置法绘制各种电气符号，并连 线形成完整的图形。 作图步骤（略）

9.6 图形输出
9.6.1创建和管理布局
布局空间又称图纸空间，可以认为是建立与工 程图纸相对应的绘图空间，是由一张图纸构成 的平面，用来创建最终供打印机或绘图仪输出 图纸所用的平面图。
是表示设备系统的工作原理、空间关系或者元器件的连接关系，能够 反映设备系统全部状态的一种图样。系统图与平面图相结合能准确地 反映系统的全貌和工作原理。
