轴的CADCAM课程设计

一．零件分析

零件图

1.1.工艺分析

该零件是减速器中的传动轴。

它属于台阶轴类零件，由圆柱面、轴肩、螺纹、退刀槽、砂轮越程槽和键槽等组成。

轴肩一般用来确定安装在轴上零件的轴向位置，各环槽的作用是使零件装配时有一个正确的位置，并使加工中磨削外圆时退刀方便；键槽用于安装键，以传递转矩。

（1）.毛坏确定

该轴长度154m，最大直径30mm，所以可选取直径35mm长度160mm的圆柱棒料作为毛坏。

材料选45号钢。

（2）.基准选择

毛坯外圆作粗基准，先加工一个端面，，车出一端外圆；然后用已加工过的外圆作基准，用三爪自定心卡盘装夹，车另一端面和外圆。

1.2.工艺路线确定

下料→粗车一端端面及外圆→粗车另一端端面及外圆、精车该端外圆、倒角、车槽→精车另一端外圆、倒角、车槽→铣键槽→磨外圆→去毛刺

二．CAD设计过程

2.1．三维建模

.首先绘制轮廓草图

.经过旋转

.经过倒角与圆角

.创建基准面1，绘制键槽草图

（5）.通过拉伸切除，可得键槽

（6）.同理，可得第二个键槽

2.2．绘制工程图

三.CAM设计过程

3.1.MasterCAM加工设置

3.1.1.车床加工

（1）粗加工一端

车端面参数

粗车外圆参数

毛坏设置与车外圆路径

仿真结果

（2）粗加工另一端

经素材翻转后，参数设置同上，可得另一端仿真结果

（3）精加工一端

该端精车、车槽参数设置

该端最后仿真结果

（4）精加工另一端

经翻转后，另一端精车，参数设置同上，车槽后最后仿真结果

3.1.2.铣床加工

首先将未铣键槽的轴选为工件材料，然后绘制键槽草图，接着刀具路径中选择铣键槽，通过设置相关参数，完成键槽加工。

刀具路径和最后仿真结果如下：
