左箱體的加工質(zhì)量將直接影響機(jī)器的性能和使用壽命。本次設(shè)計(jì)旨在提高左箱體的加工效率，由此我們首先對(duì)左箱體的結(jié)構(gòu)特征和工藝進(jìn)行了仔細(xì)的分析，然后確定了一套合理的加工方案，加工方案要求簡(jiǎn)單，操作方便，并能保證零件的加工質(zhì)量。
夾具結(jié)構(gòu)設(shè)計(jì)在加深對(duì)課程基本理論的理解和加強(qiáng)對(duì)解決工程實(shí)際問(wèn)題能力的培養(yǎng)方面發(fā)揮著極其重要的作用。利用更好的夾具可以保證加工質(zhì)量，機(jī)床夾具的首要任務(wù)是保證加工精度，特別是保證被加工工件的加工面與定位面以及被加工表面相互之間的位置精度；提高生產(chǎn)率、降低成本，使用夾具后可以減少劃線、找正等輔助時(shí)間，且易于實(shí)現(xiàn)多工位加工。擴(kuò)大機(jī)床工藝范圍，在機(jī)床上使用夾具可使加工變得方便，并可擴(kuò)大機(jī)床工藝范圍。減輕工人勞動(dòng)強(qiáng)度，保證生產(chǎn)安全。為了讓夾具有更好的發(fā)展，加快用高新技術(shù)改造和提升夾具技術(shù)水平的步伐，創(chuàng)建夾具專(zhuān)業(yè)技術(shù)網(wǎng)站，充分利用現(xiàn)代信息和網(wǎng)絡(luò)技術(shù)，與時(shí)具進(jìn)地創(chuàng)新和發(fā)展夾具技術(shù)。
本次設(shè)計(jì)是制訂LH180MQ左箱體工序卡及銑鏜結(jié)合面夾具設(shè)計(jì)，設(shè)計(jì)正確的加工工藝路線。這次設(shè)計(jì)涉及到機(jī)床，機(jī)械加工工藝，工裝夾具等機(jī)制專(zhuān)業(yè)的幾乎所有的專(zhuān)業(yè)基礎(chǔ)知識(shí)。是一次全面地，系統(tǒng)地檢查自己在大學(xué)期間對(duì)專(zhuān)業(yè)知識(shí)學(xué)習(xí)的情況，在整個(gè)設(shè)計(jì)過(guò)程中做到嚴(yán)謹(jǐn)認(rèn)真，一絲不茍的精神，盡量使自己的設(shè)計(jì)達(dá)到理想的水平，通過(guò)獨(dú)立的查找資料，分析，計(jì)算完成方案設(shè)計(jì)，圖紙?jiān)O(shè)計(jì)和編寫(xiě)技術(shù)文件等，設(shè)計(jì)了這套比較完整的加工工藝路線，使自己對(duì)機(jī)制專(zhuān)業(yè)有了更深刻的認(rèn)識(shí)。

Title Make LH180MQ Left Box Process Card and
Milling Boring With Surface Fixture Design
Abstract
The processing quality left box will directly influence the machine performance and long service life. The design aims to improve the machining efficiency left box, we first left box structure characteristics and process the careful analysis, then determines a reasonable set of processing scheme, the processing plan requirement is simple, easy to operate, and can ensure the process quality of parts.
Structure design of fixture in the course of the basic theory of understanding and strengthening the ability to solve practical problems in cultivating play a very important role. Using better fixture can ensure the process quality and the machine tool's fixture priority is to ensure machining accuracy, especially that of the machining process and positioning surface and processed surface between the position precision, Improve productivity and reduce cost, use fixture after is crossed, can reduce the auxiliary time, and is easy to realize the multistage process. Expand machine technology, in machine can make use of jigs, and easy machining scope expanding machine craft. To reduce the labor intensity, ensure the safety in production. In order to make better development, clamp with high-tech transformation and accelerate the pace of ascension fixture technology level, professional technology to create fixture, make full use of modern information websites and network technology, with land development and innovation fixture technology.
This design is LH180MQ formulation process card and left box with surface milling and boring fixture design, design the correct processing route. This design involves machine, mechanical processing, jig professional mechanism of almost all the basic specialized knowledge. A comprehensive, systematic examination oneself in university period of professional knowledge, in the whole process of design, meticulous carefully accomplish precise of spirit, try to make yourself to achieve the desired level of design, through the analysis of the independent calculation, searching information, complete design, drawing design and technical documents written, design the comparatively complete processing route, make yourself to a more profound professional mechanism.
