【正文】 nary engine bed unsuitable multi varieties, the small volume production request, the numerical control engine bed synthesized the numerical control technology, the micro electron technology, the automatic detection technology and so on the advanced technology, most is suitable processes the small batch, the high accuracy, the shape is plex, the production cycle requests the short ponents. When change processing object only needs to trade the ponents processing procedure, does not need to make any adjustment to the engine bed, therefore can satisfy the product frequent change well the processing request. If engine bed equipment pletely renewal, not only fund investment is too big, the cost is too high, moreover the original equipment will leave unused creates the enormous waste. Therefore the most economical means are carry on the ordinary engine bed the numerical control transformation. Use the numerical control transformation technology, not only was allowed to cause the transformation of the engine bed to meet the technological development needs, enhanced the productivity and the product precision,increased the equipment adaptiveness and the shape processing scope, but also was allowed to make up orders the new numerical control engine bed delivery cycle long insufficiency. Therefore uses this method to the middle and small enterprises is the extremely good choice. CA 6140 is the conventional lathe that has the good performance, the advanced structure, and the operation of it is very the uses of it in our country machine manufacture profession are extremely wide. The design takes it is the example, mainly introduces the plan of its numerical control transformation , as well as the spot shaping of the transformation and the design calculation.【Keywords】: CA6140laths , the numerical control transformation, design目錄前 言 1一 CA6140臥式車床的簡介 31．機(jī)床的特點(diǎn)與用途 32. 機(jī)床的主要結(jié)構(gòu) 33．傳動系統(tǒng)的分析 4二 總體改造方案 7三 進(jìn)給系統(tǒng)的主要設(shè)計(jì)計(jì)算 10 102．步進(jìn)電機(jī)的匹配選擇 123．滾珠絲杠的校核 12四 刀架的選型 14結(jié)束語 16參考文獻(xiàn) 17謝辭 18前 言機(jī)械制造業(yè)在國民經(jīng)濟(jì)中具有十分重要的地位和作用。采用數(shù)控改造技術(shù)，不但可以使改造后的機(jī)床滿足了技術(shù)發(fā)展的需要，提高了生產(chǎn)率和產(chǎn)品精度，增大了設(shè)備適應(yīng)能力和型面加工范圍，還可以彌補(bǔ)定購新的數(shù)控機(jī)床交貨周期長的不足。而普通機(jī)床已不適應(yīng)多品種、小批量生產(chǎn)要求，數(shù)控機(jī)床則綜合了數(shù)控技術(shù)、微電子技術(shù)、自動檢測技術(shù)等先進(jìn)技術(shù)，最適宜加工小批量、高精度、形狀復(fù)雜、生產(chǎn)周期要求短的零件。當(dāng)變更加工對象時(shí)只需要換零件加工程序，無需對機(jī)床作任何調(diào)整，因此能很好地滿足產(chǎn)品頻繁變化的加工要求。所以采用此方法對中、小型企業(yè)來說是十分理想的選擇。機(jī)械制造業(yè)提供的裝備水平對國民經(jīng)濟(jì)各部門的技術(shù)進(jìn)步有著很大的和直接的影響。
