畢業(yè)設(shè)計(jì)說(shuō)明書(論文)中文摘要
機(jī)床尾座零件加工工藝及夾具設(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

Title :The design of the tailstock parts processing technology and fixture of machine tool
Abstract
Automobile gearbox cover parts processing and fixture design process design, including machining process design and fixture three. In process design should first of all parts for analysis, to understand part of the process to design blank structure, and choose the good parts machining datum, design the process routes of the parts; then the parts of each step in the process to the size calculation, the key is to determine the craft equipment and the cutting dosage of each working procedure design; then the special fixture, the fixture for the various components of the design, such as the connecting part positioning devices, clamping element, a guide element, fixture and machine tools and other components; positioning error calculated by the analysis of fixture, jig structure the rationality and the deficiency, pay attention to improving and will design in.
Keywords :process, process, cutting dosage, clamping, positioning
