1、 理工类本科毕业论文 论论 文文 题题 目目 箱体箱体零件的加工工艺规程及其夹具设计零件的加工工艺规程及其夹具设计 专专 业业 班班 级级 学学 号号 学学 生生 指 导 教 师指 导 教 师 日日 期期 2019 摘摘 要要 制造工艺是制造技术的灵魂、核心和关键，是生产中最活跃的因素。其过程是采用金属切削刀 具或磨具及其他加工方法来加工工件，使工件达到所要求的形状、尺寸、表面粗糙度和力学物理性 能，从而生产出合格零件。夹具的使用可以有效的保证加工质量，提高生产效率，降低生产成本， 扩大机床的工艺范围，减轻工人劳动强度，保证安全生产等。考虑到机械加工工艺安排及夹具的使 用在箱体的生产中直接影响
2、到其加工质量和生产效率等，所以研究箱体的机械加工工艺及夹具设计 的课题有着十分重要的意义。 当代机械制造业主要采用单件生产、多品种/小批量和重复大批量生产等多种方式。多样化经营 模式、工艺复杂，所需设备和工装繁多。目前采用 CAPP 编制工艺很普遍，成组工序允许采用同一设 备和工艺装置，以及相同或相近的机床调整方式来加工全组零件。成组技术亦可应用于零件加工的 全工艺过程。采用先进的机床和刀具，工序集中，使加工高效、简洁、可靠，简化生产计划和生产 组织工作。夹具最早出现在 18 世纪后期，随着科学技术的不断进步，夹具已从一种辅助工具发展为 门类齐全的工艺装备。近年来，数控机床、加工中心、成组技术
3、、柔性制造系统等新加工技术的应 用，对机床夹具提出了很多新的要求。 Manufacturing process is the soul, core and key of manufacturing technology. It is the most active factor in production. The process is to use metal cutting tools or abrasives and other processing methods to process the workpiece, so that the workpiece to achieve th
4、e required shape, size, surface roughness and mechanical and physical properties, so as to produce qualified parts. The use of fixture can effectively ensure the quality of processing, improve production efficiency, reduce production costs, expand the scope of machine tools, reduce labor intensity,

Taking into account the arrangements for the use of mechanical processing technology and fixture in the pump body production directly affects the machining quality and production efficiency, has a very important significance of mechanical processing technology and fi
6、xture design task so the study on pump body. The modern machine manufacturing industry mainly adopts many ways, such as single production, multi species / small batch and repeated mass production. Diversified business model, complex process, equipment and tooling required. At present, it is very common to use CAPP to make the whole set of parts. The group process allows the same equipment and
