阀体的加工工艺及铣67上端面夹具设计
摘要
本设计主要内容包括阀体的加工工艺及铣夹具设计。在设计过程中完成了零件图、毛坯图、夹具装配图和夹具体等所有非标零件图的绘制及说明书的编写。
本次设计的零件—阀体是汽车上重要的零件之一。该零件的作用能够控制流体实现不同方向、不同压力、不同流量的转换。通过对零件图的分析，该零件圆柱孔、螺纹孔比较多，孔与孔之前的公差、位置要求比较高。通过对零件毛坯、生产类型、工艺路线及切削用量的确定。完成阀体全部加工需经过铣削、车削以及钻削加工。
本次铣夹具针对零件图仰视图67上端面设计了一套铣床专用夹具，采用支承板、定位座、定位块来满足定位要求，又通过夹紧装置保证加工过程中不会产生较大误差。其中间过程对夹紧装置进行了受力分析，保证了夹紧的可靠性。

ABSTRACT
The main contents of this design include thevalve body processing technology and milling fixture design. In the design process to complete the parts drawings, rough drawings, fixture assembly drawings and clamps and all non-standard parts of the drawing and description of the preparation.
The design of the parts- thevalve body is one of the important parts of the car. The role of the part can control the fluid to achieve different directions, different pressures, different flow conversion. Through the analysis of the parts map, the parts cylindrical holes, threaded holes more holes and holes before the tolerances, the location of relatively high. Through the rough parts, production types, process routes and cutting the amount of determination. Complete thevalve body to be processed through milling, turning and drilling.
The milling fixture for the bottomview of the parts drawings 67 designed a set of milling machine dedicated fixture, using the support plate, positioning seat, positioning block to meet the positioning requirements, but also through the clamping device to ensure that the processwill not have a greater error. The middle process of the clamping device for the force analysis to ensure the reliability of the clamping.
