摘     要
 此次設(shè)計(jì)是對(duì)ZLY630外鏈板的加工工藝和夾具設(shè)計(jì)，其零件為鍛件，具有體積中等，零件結(jié)構(gòu)簡(jiǎn)單的特點(diǎn)，由于面比孔易加工，在制定工藝規(guī)程時(shí)，就先加工面，再以面為基準(zhǔn)來(lái)加工其它，其中各工序夾具都采用專(zhuān)用夾具，特別的對(duì)于加工圓弧的工序中，選一面兩銷(xiāo)的定位方式，并以操作簡(jiǎn)單的手動(dòng)夾緊方式夾緊，其機(jī)構(gòu)設(shè)計(jì)簡(jiǎn)單，方便且能滿足要求。機(jī)械加工工藝是規(guī)定產(chǎn)品或零件機(jī)械加工工藝過(guò)程和操作方法。生產(chǎn)規(guī)模的大小、工藝水平的高低以及解決各種工藝問(wèn)題的方法和手段都要通過(guò)機(jī)械加工工藝來(lái)體現(xiàn)。而機(jī)床夾具是在機(jī)床上用以裝夾工件的一種裝置，其作用是使工件相對(duì)于機(jī)床或刀具有個(gè)正確的位置，并在加工過(guò)程中保持這個(gè)位置不變。它們的研究對(duì)機(jī)械工業(yè)有著很重要的意義。

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.
