2633 法蘭零件落料沖孔復(fù)合模具設(shè)計(jì),法蘭,零件,沖孔,復(fù)合,模具設(shè)計(jì) 摘 要隨著生產(chǎn)力水平的發(fā)展，數(shù)控技術(shù)越來越廣泛的應(yīng)用于各個(gè)領(lǐng)域。數(shù)控機(jī)車是數(shù)控技術(shù)最普遍的應(yīng)用。而數(shù)控回轉(zhuǎn)工作臺(tái)是一種可以實(shí)現(xiàn)圓周進(jìn)給和分度運(yùn)動(dòng)的工作臺(tái)，它常被使用于臥式的鏜床和加工中心上，可提高加工效率，完成更多的工藝，它主要由原動(dòng)力、齒輪傳動(dòng)、蝸桿傳動(dòng)、工作臺(tái)等部分組成，并可進(jìn)行間隙消除和蝸輪加緊，是一種很實(shí)用的加工工具。本課題主要介紹了它的原理和機(jī)械結(jié)構(gòu)的設(shè)計(jì)。本課題主要介紹了它的原理和機(jī)械結(jié)構(gòu)的設(shè)計(jì)，并對(duì)以上部分運(yùn)用AtuoCAD做圖,最后是對(duì)數(shù)控回轉(zhuǎn)工作臺(tái)提出的一點(diǎn)建議。 關(guān)鍵詞：數(shù)控回轉(zhuǎn)工作臺(tái) 齒輪傳動(dòng) 蝸桿傳動(dòng) 間隙消除 蝸輪加緊 AbstractAlong with the development of productivity, the numerical control technology is widely used in various fields. CNC locomotive is the most common numerical control technology application. CNC rotary worktable and can realize the circle is a kind of degree movement and went to the bench, it is often used in the horizontal boring and milling center, can improve the efficiency of the machining process, complete more, it mainly consists of impulsion, gear, worm transmission, workbench components, and can eliminate gear up, and the gap is a very practical machining tools. This subject mainly introduces its principle and mechanical structure design. This subject mainly introduces its principle and mechanical structure design, and to make more use AutoCAD, CNC rotary worktable is finally proposed some Suggestions.Keyword：Numerical control rotary table； Gear drive；Worm drive；Gap elimination； The worm gear steps up. 目 錄引 言
