【正文】 軸向調(diào)節(jié)機(jī)構(gòu)、鎖緊機(jī)構(gòu)等）所有零件的設(shè)計(jì)。 本次設(shè)計(jì)的題目是銑削組合機(jī)床及主軸組件。摘 要 組合機(jī)床，是由大量的通用部件和少量專用部件組成的工序集中的高效率機(jī)床。其特點(diǎn)有：結(jié)構(gòu)緊湊、工作質(zhì)量可靠、設(shè)計(jì)和制造周期短、投資少、經(jīng)濟(jì)效果好、生產(chǎn)率高等。首先針對(duì)所要加工的零件入手，對(duì)機(jī)床進(jìn)行總體方案設(shè)計(jì)，進(jìn)而確定機(jī)床的總體布局，隨后，對(duì)主軸組件進(jìn)行設(shè)計(jì)。 設(shè)計(jì)機(jī)械加工工藝規(guī)程遵循如下原則： 1） 保證零件圖樣上所有技術(shù)要求的實(shí)現(xiàn)。 3） 在滿足技術(shù)要求和生產(chǎn)綱領(lǐng)要求的前提下，要求工藝成本最低，低耗節(jié)能。維護(hù)環(huán)境衛(wèi)生。 關(guān)鍵詞 ： 組合機(jī)床，主軸組件，主軸，軸承，軸向調(diào)節(jié)機(jī)構(gòu) Abstract Modular Machine, by the large number of mon parts and a small number of specialized ponents of the process focused efficient machine. Its features include pact, reliable quality, design and manufacturing cycle shorter, less investment and economic effects, and higher productivity. The design is the subject of bined milling machine spindle ponents. First of all, for the processing of parts to start with a general program of machine design, machine tool and then determine the overall layout, then the design of the main ponents. Components in the design of the spindle to spindle for clues, to meet the stiffness and precision required to plete the other (such as bearings, axial adjustment agencies, locking, etc.) the design of all parts. Design mechanical processing order to follow the following principles 1) To ensure that all parts drawings on the realization of the technical requirements. 2) Program must be able to meet production requirements. 3) To meet the technical requirements and requirements of the production program, under the premise of the minimum requirements of cost, low energy. 4) Minimize the labor intensity of workers, protection of production safety. This product is based on user requirements and design, the user discussion after passing the production, hope the guide, identified.
