被动轴的加工工艺及夹具设计
摘要
设计内容被动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，钻床专用夹具两部分。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。对零件被动轴的零件图进行了分析，知晓该被动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40Cr。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钻90°交角Ф6.5通孔而设计的。采用Z3040摇臂钻床进行加工。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。还对钻套、钻削力等进行选择与计算。

ABSTRACT
Design the processing technology and fixture design of the passive axis. Through the interpretation of the task book, the contents include two parts processing technology, special fixture for drilling machine. On the basis of mastering the function of parts and analyzing them, the design contents of the two parts are completed.
Prior to the design, the contents of the special fixture part of the machine toolwere understood and mastered. The part drawing of the passive shaft is analyzed. It is known that the function of the passive axis is to transmit the related motion and power, because the load that the part bears in thework is notvery large, thework is relatively stable, and the material is the common 40Cr. The processing routewas compiled, the process card and the process cardwere filled out, and the corresponding cutting datawere calculated. The blank drawing of parts is completed, and the blank is made of round steel.
The special fixture designed is designed to drill 6.5 degrees through 90 angles. The Z3040 rocker drilling machine is used for processing. On the basis of clear positioning principle, the design of part positioning scheme is completed; the positioning element is selected; the clamping scheme design is completed; and the clamping element is selected. The drill sleeve and drilling force are also selected and calculated.
Keywords passive shaft, processing technology, drilling 90 degree angle, 6.5 hole, clamp, Z3040
