钻夹体加工工艺及钻床夹具计论文.docxVIP

摘要钻夹体加工工艺及钻床夹具设计是包括零件加工的工艺设计，工序设计，以及专用夹具的设计三部分。在工艺设计中要首先对零件进行分析，了解零件的工艺在设计出毛坯的结构，并选择好零件的加工基准，设计出零件的工艺路线；接着对零件的各个工步的工序进行尺寸计算，关键是决定出各个工序的工艺装备及切削用量；然后进行专用夹具设计，选择设计出夹具的各个组成部件，如定位元件，夹紧元件，引导元件，夹具体与机床的连接部件以及其他部件；计算出夹具定位产生的定位的误差，分析夹具结构的合理性与不足之处，并在以后设计中进行改进。这次设计使我们能综合运用大学中学过的课程，如机械制图、理论力学、材料力学、机械设计技术基础、机械制造技术基础、机械制造工艺学中的基本理论，并结合生产实习中学到的实践知识，独立地分析和解决工艺设计问题，初步具备了设计一个中等复杂零件（杠杆）的工艺规程的能力和运用夹具设计的基本原理和方法。在完成夹具结构设计的同时，也是熟悉和运用有关机械夹具设计手册、图表、网络等技术资料及编写技术文件等基本技能的一次全面实践机会。关键词：工序；切削用量；夹紧；定位；定位误差AbstractThe drill clamp body processing technology and drilling fixture design process design, including machining process design and fixture design, the three part. In the process of design should first understand the analysis of parts, parts of the process in the design of blank structure, and choose the good components the processing datum, designs the process routes of the parts; then each labor step on the part of the process of size calculation, is the key to decide the craft equipment and the cutting of various process parameters; then for the design of special fixture, the fixture selection for the various components of the design, such as the positioning element, the clamping element, a guide element, clamp is connected with the machine specific components and other components; the calculated error produced by the positioning fixture, analysis the rationality and shortcoming of fixture structure is improved, and in later design.This design allows us to use the comprehensive high school through university courses, such as mechanical drawing, theoretical mechanics, materials, mechanical design technology infrastructure, machinery manufacturing technology, machinery manufacturing technology in the basic theory, combined with production practice learned practical knowledge, independent analysis and problem solving process design, initially with the basic principles and methods of the ability to design a moderately complex parts (leverage) process planning and use of fixture design.
