镗床主轴零件图A2
摘要
本次设计的主要内容是镗床主轴的加工工艺及夹具设计。通过对任务书的解读，内容有加工工艺规程，专用夹具两部分。在掌握零件作用以及对其进行分析的基础上，完成了这两部分的设计内容。
在进行设计之前，对机床专用夹具部分的内容进行了了解和掌握。对零件镗床主轴的零件图进行了分析，知晓该镗床主轴的作用是传递相关的运动和动力，因为零件在工作中承受的载荷不是很大，工作相对平稳，其材料是常见45钢，并经正火处理。编写了加工工艺路线，填写过程卡还有工序卡，对其中相应切削数据进行计算。完成了零件毛坯图的绘制，坯料用圆钢。
本次设计的专用夹具是为加工宽8，长22槽而进行的。采用立式铣床进行加工。在明确定位原理的基础上，完成零件定位方案的设计；选择了定位元件；完成夹紧方案的设计；选择了夹紧元件、对刀块、铣削力等。

Abstract
The main content of this design is the processing technology and fixture design of the spindle of the boring machine. Through the reading of the task book, the content has processing technology regulations, special fixture two parts. The design content of the two parts is completed on the basis of the analysis of the role of the parts and the analysis of them.
Before the design is carried out, the content of the special fixture part of the machine tool is understood and mastered. The part diagram of the spindle of the boring machine is analyzed. It is known that the spindle function of the boring machine is to transmit related motion and power, because the load that the part bears in thework is notvery large, and thework is relatively stable. The material is common 45 steel and normalizing. The processing route iswritten, the filling process card and the process card are filled in, and the corresponding cutting data are calculated. The drawing of the blank drawing of the parts is completed, and the billet is made of round steel.
The special fixture designed in this design is made for 8wide and 22 grooves. Thevertical milling machine is used for machining. On the basis of clear positioning principle, the design of parts location plan is completed, the positioning elements are selected, the clamping scheme is designed, and the clamping elements, cutter block and milling force are selected.
Keywords: boring machine; spindle; processing technology; fixture design
