摘要
专用夹具在现在的机械加工过程中发挥着重要的作用，实现了加工件的定位和夹紧。本次设计研究的对象是CA10B解放牌汽车后钢板弹簧吊耳。主要研究的内容包括零件的加工工艺设计及铣侧面专用夹具的设计。
CA10B解放牌汽车是典型的汽车之一，后钢板弹簧吊耳为弹簧及主要零部件的定位和工作提供支撑，为汽车的正常工作护航。在对加工工艺设计之前，首先完成了零件作用及零件图的分析，确定了零件的生产类型，制造方式及加工余量，绘制毛坯图。设计加工工艺路线，计算工序卡中涉及到的切削用量等。最后，完善了工艺卡及工序卡。
本次加工的零件设计的内容为：确定零件的定位方案（满足6点定位原理）；选择夹紧装置还有夹紧元件；对夹具体进行了设计和确定；为保证零件的加工精度，设计了对刀装置（对刀块）；对零件在装夹过程中的夹紧力和切削力进行计算等等。最后，完成专用夹具的夹具装配图还有所有非标准的零件图。

Abstract
The special fixture plays an important role in the present machining process,which realizes the positioning and clamping of theworkpiece. The research object of this design is CA10B Jiefang car rear leaf spring lifting lug. The main research contents include the design of machining process and the design of special fixture for milling side.
CA10B Jiefang car is one of the typical cars. The rear leaf spring lifting lug provides support for the positioning andworking of the spring and main parts, and escorts the normalwork of the car. Before the design of processing technology, the function of parts and the analysis of part drawing are completed. The production type, manufacturing mode and machining allowance of parts are determined, and the blank drawing is drawn. Design the processing route, calculate the cutting parameters involved in the process card. Finally, the process card and process card are improved.
The design contents of the parts are: determine the positioning scheme of the parts(meet the 6-point positioning principle); select the clamping device and clamping element; design and determine the clamp; design the tool setting device(tool block) to ensure the machining accuracy of the parts; calculate the clamping force and cutting force in the clamping process of the parts. Finally, complete the fixture assembly drawing of special fixture and all non-standard part drawing.
Keywords: CA10B Jiefang car; rear leaf spring lifting lug; processing technology; side milling
