摘     要
 此次设计是对ZLY630外链板的加工工艺和夹具设计，其零件为锻件，具有体积中等，零件结构简单的特点，由于面比孔易加工，在制定工艺规程时，就先加工面，再以面为基准来加工其它，其中各工序夹具都采用专用夹具，特别的对于加工圆弧的工序中，选一面两销的定位方式，并以操作简单的手动夹紧方式夹紧，其机构设计简单，方便且能满足要求。机械加工工艺是规定产品或零件机械加工工艺过程和操作方法。生产规模的大小、工艺水平的高低以及解决各种工艺问题的方法和手段都要通过机械加工工艺来体现。而机床夹具是在机床上用以装夹工件的一种装置，其作用是使工件相对于机床或刀具有个正确的位置，并在加工过程中保持这个位置不变。它们的研究对机械工业有着很重要的意义。

The processing craft and the jig design of ZLY630 outer chain plate
Abstract
    This design is the processing craft and the jig design of the ZLY630 outside chain plate, its components are the forging, it has the medium volume and simple structure components,Because the surface is easier than the hole to process, so when formulating the technological process, processing surface firstly，then processes other take the surface as the datum,In which various working procedures jig all uses the unit clamp, specially such as processing the arc, chooses locate mode of one surface two melt and the simple manual clamp way to clamp, its organization design is simple, convenience and also can satisfy the request. The machining process prescribes the machining process and operating methods of products and the components. The size of the production, the level of process and the methods and means to solve various process problems should be reflected by the machining process. The machine tool's fixture is a device to clamp workpiece in the machine, its function is to make the workpiece which relative to the machine or aword have a corret position, and keep this in the machining process. Their study has a very important significance for the mechanical industry.
