Processing pla n formulation The division working procedure needs to consider to the production scale, the processing precision, uses the engine bed the character istic, the static load situation and so on. The division working procedure ma y have two kind of trends: The working procedure centralism and the working procedure are dispersible. The working procedure centralism disperses has its strong point respectively, in genera l, by enhances the productivity in the mass production prima rily, must widely use the multi knives, the single axle and multiple spind le is automa tic or the semia utoma tic engine bed, multiple spind le pla nertype milling machine, aggregate machinetool and so on, therefore adopts the working procedure centralism to be possible to obtain the prominent effect. In this design bearing seat drill hole aggregate machinetool very great degree causes various working procedures to concentrate as far as possible, the displa y aggregate machinetool mer it, at the same time causes each kind of error to reduce to the threshold. Because in this design processes in the ponents 10 holes the partial holes are away from too near, is not advantageous for the processing, therefore separates is two locations pletes, then carries on the ponents position transformation. Below the ma in location selects the pla n after the analysis: 1) loads and unloads, cla mps。 Cutter bar guida nce partial tolera nces: ~ 。 由于此設(shè)計(jì)中所加工的零件10個(gè)孔中部分孔距離太近，不便于加工，所以分開(kāi)為兩 個(gè)工位完成，然后進(jìn)行零件位置轉(zhuǎn)換。= 3）.選用電機(jī) 由于此機(jī)床在驅(qū)動(dòng)方面沒(méi)有特殊的要求，選用普通也是最可靠的Y系列電機(jī)，它是封 閉自扇冷式鼠籠型三相異步電動(dòng)機(jī)，取代J02系列的更新?lián)Q代產(chǎn)品。利用球頭螺栓使壓板緊壓住工件體。其配方為：油膏2%～5%，粗加工取低值，精加工取高值。選擇合適的電機(jī)和動(dòng)力頭，選擇恰當(dāng)?shù)那邢饔?量和切削速度。因而選擇冷卻液時(shí)，應(yīng)根據(jù)組合機(jī)床完成工藝 、 加工方法、刀具材料以及被加工零件的材料來(lái)決定。夾緊力作用點(diǎn)數(shù)目應(yīng)使工件在整個(gè)接觸面上受力均勻，接觸 8徐州 工 程 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (論文 )變形小。 每一種規(guī)格的動(dòng)力頭都有一定的功率范圍，根據(jù)所計(jì)算出的切削功率及進(jìn)給功率之需 要，并適當(dāng)提高切削用量的可能性，選用相應(yīng)規(guī)格的動(dòng)力頭，公式如下：N動(dòng)(N切+N進(jìn))/hkW。 劃分工序要考慮到生產(chǎn)的規(guī)模、加工的精度、所用機(jī)床的特點(diǎn)、機(jī)床負(fù)荷情況等。 Rotationa l speed 350r/Min.
