【正文】 er these circulation also needs other parts, like moves the work table, coordina te movement and so on rotary table as well as drum wheel. Various powers part keeps off the iron with the aid of the procedure control, carries on the work according to the stipulation order. The operating cycle must as far as possible be simple moreover controls the part to be supposed to be few, otherwise the engine bed production cost enlarges, the security performa nce also can reduce. This aggregate machinetool suits in the mass production uses, the production efficiency enhances greatly. In order to reduce the cost, should select the pound cutting tool, achieves a time of forming as far as possible, reduces the attire to cla mp the number of times. Chooses the appropriate electrical machiner y and the power head, chooses the appropriate cutting specifications and the cutting speed. 5 徐州 工 程 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (論文 )附錄 2中文譯文立式軸承座鉆孔組合機(jī)床設(shè)計(jì) 作者：Cnsaw 1分工序、定工位 此次設(shè)計(jì)的立式軸承座鉆孔組合機(jī)床，其所加工的零件在汽車中應(yīng)用十分廣泛，應(yīng)該 屬于大批量生產(chǎn)項(xiàng)目，所以在設(shè)計(jì)時應(yīng)注意到盡量使加工簡單，但又不影響加工質(zhì)量。 N cuts is the cutting power, selects the cutting specifications according to various cutting tools, center has extracted by 2 徐州 工 程 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (論文 )the aggregate machinetool cutting force and the power formula。 S= ( ~ ) mm/R。 3) drills 3 holes is f14, drills 2 threads bottom holes f14, Kong Haowei 8, 9。 6) attacks the silk. 2 pound cutting tools cutting specificationses putation specifications character istic The aggregate machinetool norma l work and reasonably selects the cutting specifications, namely the determination reasonable cutting speed and the work enters to the quantity has the very big relations. The cutting specifications elects the inappropriateness, can cause the aggregate machinetool to reduce stops the loss, enhances the production efficiency, lengthens the cutting tool life, improves the processing quality. a set of design 1徐州 工 程 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (論文 )3. Is processed 7 holes dia meters is , the processing hole dia meter with leads a set of length, leads the set of inside dia meter size, about the deviation as well as the hole spool thread idea l position displacement relations, like table 1 shows. 4. May know 1 ~ 7 holes by table 1, as well as 8 ~ 10 holes and the bottom hole dia meters are mm, it needs leads a set of length for (32 ~ 40) mm, the inside dia meter size deviation is + ~ +, hole spool thread idea l disa lignment for ( ~ ) mm. 5. Hole processing cutting specifications putation A Processes this casting HB=204 with the highspeed steel drill bit (to drill 1 ~ 7 holes, II location。 Reamer cutter bar and guida nce partial nomina l dia meter d+。= the electrical machiner y As a result of this engine bed in the actuation aspect not specia l request, selects ordinary also is the most reliable Y series electrical machinery, it is the seal from fan Leng Shishu the cage threephase asynchronous motor, substitutes for the J02 series the renewa l product. The le ft half branch needs the power is , looks up Y series threephase asynchronous motor table, selects the Y123S24 model the electrical machinery, the rated power is , selects this model electrical machiner y quite to be appropriate. The right half branch needs the power is , looks up Y series threephase asynchronous motor table, selects the Y112M26 model the electrical machinery, the rated power is , selects this model electrical machiner y quite to be appropriate. 4 jigs designs 1.

According to the work piece different working condition, ma y differently have each kind to insta ll the method: A) adjusts the peaceful process。 工序的集中分散各有其長處，一般說來， 在大批量生產(chǎn)中以提高生產(chǎn)率為主，需廣泛采用多刀、單軸與多軸自動或半自動機(jī)床，多 軸龍門銑床、組合機(jī)床等，故采取工序集中可以獲得突出的效果。5）.孔加工切削用量計(jì)算=204(鉆1～7號孔，Ⅱ工位；鉆8～10號孔，Ⅲ工位)； 鉆頭直徑：；切削用量：v=(10～18)m/min，s=，轉(zhuǎn)速350r/min。2）.機(jī)床實(shí)際功率 此立式組合機(jī)床左右分兩個電機(jī)帶動兩個多軸箱進(jìn)行加工。如果采用一定的約束措施，消除物體的6個自由度，則物體被完全 定位。 如果利用半圓形定位， 最后決定利用定位套筒定位。故綜合考慮 選用攻絲裝置攻絲。在大量生 產(chǎn)中有時為了減少加工中的鐵粉飛揚(yáng)，也增加冷卻系統(tǒng)，以改善操作條件。國外資料推薦按加工直徑選擇，每把刀具的冷卻液流量，值見
