文档介绍：基于三维的柴油机气缸盖组合钻床总体及夹具设计
摘要:本设计课题来源于盐城市江淮动力集团。柴油机气缸盖是需要大量生产的零件,为了提高加工精度和生产效率,需要设计一种组合机床来改善柴油机气缸盖的加工情况。本组合机床是针对ZH1105柴油机气缸盖上面排气道面上2×M10—7H螺纹底孔,井气道上4×M10-7H螺纹底孔,G3/8"放置螺塞底孔同时加工的需要而设计的。该设计的内容包括总体设计和夹具设计两方面。在总体设计中分析了被加工零件的加工工艺性,选择了加工的定位基准及夹紧方案,合适的切削用量、刀具、及机床的配置型式,合适的结构方案等,同时完成了“三图一卡”的绘制。在夹具设计方面,采用了专用夹具,用符合六点定位原则的“一面两孔”定位方案消除工件的六个自由度,使工件获得稳定可靠的定位,并有同时加工零件两个表面的可能,能高度集中工序。夹紧装置则选用比较安全、可靠、方便的液压夹紧装置,使夹紧平稳可靠。本组合机床效率高,成本低,加工精度高,操作使用方便,减轻了工人的劳动强度,提高了劳动生产率,满足了设计需要。

Abstract: The design project is from Jiangdong Dynamic Group, Yancheng. Considering a large quantity of parts needed by diesels, a modular machine tool is designed to improve the accuracy and efficiency of diesel production. bination of machine tools against ZH1105 diesel engine exhaust, cylinder head above surface 2 × M10-7H thread bottom outlet, gas wells over the 4 × M10-7H thread bottom outlet, G3 / 8 "at the same time placing Bottom. The design is mainly focused on both the overall design and jig design. The overall design makes detailed analysis of processing techonology, choice of the positioning datum of processing, grip program, proper cutting parameters, cutting tools, the configuration types of machine tools, the proper construction program and so on. Meanwhile the drawing of “Three Charts and One Card”(automatic drawing process chart, size relation chart, machining schematic diagram and production calculating card)  pleted. As far as jigs are concered, a special fixture are employed with the aid of the three platforms positioning program according to the principle of six points positioning to eliminate the six degrees of freedom of workpiece for a stable and reliable positioning, and the synchronous processing of two surfaces of parts which can simplifying the process. The safer, more reliable and convient hydraulic grip devices are employed for a stable and reliable grip. The charateristics of effiecy
