摇臂的工艺分析及钻Φ12孔夹具设计
摘要
本次夹具设计的主要目的是在确保加工零件质量的基础上，能够见制造成本降到最低，生产的效率大幅度起升，最终，实现利益的最大化。这也是当下国内外加工工艺主要的发展方向。
通过对摇臂零件图还有其外形及内部构造的分析，接而对摇臂的加工工艺、加工装备，切削用量等等进行确定。摇臂是机器上一个重要的控制零件。该零件主要用于连接上下零部件，起到传递运动和动力的作用，受力不大。完成摇臂零件图还有毛坯图的绘制。
依据指导老师分配的任务，设计钻Φ12孔钻床专用夹具的设计。专用夹具的设计主要有3部分：定位方案及元件；夹紧方案及元件；夹具体及钻套等设计。经过分析，本次设计的工艺及专用夹具，能够满足生产的需要。

ABSTRACT
The main purpose of this fixture design is to ensure that the quality of processed parts, based on the see manufacturing costs can be reduced to a minimum, the efficiency of production rose dramatically, ultimately, to maximize the benefits. This is also the main development direction of the current domestic and international processing technology.
Through the parts of the rocker arm aswell as its shape and internal structure analysis, then the rocker processing technology, processing equipment, cutting and so on to determine. Rocker arm is an important control part on the machine. The parts are mainly used to connect the upper and lower parts, play a role in the transmission of movement and power, little stress. Completion of the rocker parts drawing and rough drawing.
According to the task assigned by the instructor, the design of drilling fixture forΦ12 hole drilling machine is designed. Special fixture design has 3 main parts positioning programs and components; clamping programs and components; clamps and drill and other design. After analysis, this design process and special fixtures, to meet the production needs.
