PAGE  -  PAGE 10 - 掘进机箱体加工工艺及组合机床设计 摘 要 掘进机箱体是掘进机的重要零件。箱体的结构形式虽然多种多样，但仍有共同的特点:形状复杂、壁薄且不均匀，内部呈腔形，加工部位多，加工难度大，既有精度要求较高的孔系和平面，也有许多精度要求较低的紧固孔。因此，一般中型机床制造厂用于箱体类零件的机械加工劳动量约占整个产品加工量的15%~20%。这次的设计内容就是掘进机箱体的加工及组合机床的设计。根据.零件的技术要求编排出科学实用、方便、经济、合埋的加工上艺，并从中选扫两道上序进行夹具和组合机床的设计，总的来说就是编排一套科学、方便、经济、合理的加上方案，加工出高质量的掘进机箱体，并使其加上成本尽可能降到最低。 关键词：掘进机、箱体、孔系、组合机床、夹具。 全套图纸，加153893706Abstract Roadheader cabinet is the important se se body parts of roadheader . Enclosure structure form although varied, but still have common characteristics: complex shape, wall thin and uneven, internal cavity shape, the machining parts is more difficult, processing, have higher accuracy of the hole, and many peace surface accuracy requirements of lower tighten holes. Therefore, general medium machine tool factory for cabinet parts machining amount of whole product manufactured accounts for 15% to 20%. This design content is roadheader box processing and combination machine tools design. According to the technical requirements. Parts arrangement at a scientific and practical, convenience, economy, and buried on the processing technique, and choose Saul sequence of two way fixture and combination machine tools design, overall is arranged a set of scientific and convenient, economical and reasonable plus scheme, processing a high quality roadheader cabinet, and make it possible to a minimum. Add cost Keywords: roadheader, body, holes are, the combination machine tools and fixtures. 目 录 摘要 ··················································Ⅰ Abstract·····························································································Ⅱ 绪论··································································································· 3 一、零件分析及设计任务书 ··························································· 1 1.1掘进机箱体的工艺分析······························································· 1 1.2掘进机箱体零件的工艺要求及工艺分析··········································1 1.2.1掘进机箱体的技术要求·······························
