摘 要
本次設(shè)計(jì)內(nèi)容涉及了機(jī)械制造工藝及機(jī)床夾具設(shè)計(jì)、金屬切削機(jī)床、公差配合與測(cè)量等多方面的知識(shí)。
閥體加工工藝規(guī)程及其鉆孔的夾具設(shè)計(jì)是包括零件加工的工藝設(shè)計(jì)、工序設(shè)計(jì)以及專用夾具的設(shè)計(jì)三部分。在工藝設(shè)計(jì)中要首先對(duì)零件進(jìn)行分析，了解零件的工藝再設(shè)計(jì)出毛坯的結(jié)構(gòu)，并選擇好零件的加工基準(zhǔn)，設(shè)計(jì)出零件的工藝路線；接著對(duì)零件各個(gè)工步的工序進(jìn)行尺寸計(jì)算，關(guān)鍵是決定出各個(gè)工序的工藝裝備及切削用量；然后進(jìn)行專用夾具的設(shè)計(jì)，選擇設(shè)計(jì)出夾具的各個(gè)組成部件，如定位元件、夾緊元件、引導(dǎo)元件、夾具體與機(jī)床的連接部件以及其它部件；計(jì)算出夾具定位時(shí)產(chǎn)生的定位誤差，分析夾具結(jié)構(gòu)的合理性與不足之處，并在以后設(shè)計(jì)中注意改進(jìn)。

關(guān)鍵詞：工藝、工序、切削用量、夾緊、定位、誤差。


Abstract
This design content has involved the machine manufacture craft and the engine bed jig design, the metal-cutting machine tool, the common difference coordination and the survey and so on the various knowledge.
Body process planning and drilling fixture was designed to include part machining process design, process design, and dedicated fixture design of three parts. In process design, analysis of the part must first understand the parts of the process re-engineering the structure of a blank, and select a good part of the processing of the base to design parts process route; followed by the various working steps on the part of the procedures for the size of the calculation, the key is to determine the various stages of work out of process equipment and cutting consumption; then dedicated fixture design, selection of design out of all the component parts fixture, such as the positioning components, clamping components, guiding elements, the specific folder connection with the machine parts and other components; calculate the positioning fixture positioning error generated, analysis fixture structure is reasonable and deficiencies, and attention to improving the design in the future.

Keywords: The craft, the working procedure, the cutting specifications, clamp, the localization, the error
