【正文】 te 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(shí)應(yīng)注意到盡量使加工簡(jiǎn)單，但又不影響加工質(zhì)量。Enable the cla mp using the ball head bolt tightly to suppress the work piece body. Like chart 3 shows, in under this cla mp function, along X rotation of axis X2, as well as and degree of freedom is all limited along Z rotation of axis Z2 along Z the axis direction Z1. Therefore in under this set of jig function, degree of freedom and so on X1, Y1, Z1, X1, Y1 is eliminated pletely, but under cla mp pressure function, between ponents and cutting tool formidable friction force, as well as in the processing process midd le axle directive force mutual counterbala nce, is also eliminated in the Z degree of freedom. When carries on to IV location, when processing crosswise hole, X1, Y1, the Z1 degree of freedom was eliminated, X2, the Y2 direction degree of freedom was also eliminated, in Z2 direction, because the cla mp function caused the work piece also to eliminate at the Z2 direction degree of freedom. 5 attacks the silk insta llment Attacks the system thread when the aggregate machinetool, according to is processed the ponents processing spot the distributed situation and the technologica l requirement and so on, monly used attacks the silk method to have 3 kinds: Uses attacks the silk power taper tap silk, uses attacks the silk insta llment to attack the silk and to use the activity to attack the silk template to attack the silk. In this design, the right half part pletes V, VI location processing. Electrica l machiner y only then power, therefore the synthesis considera tion selects attacks the silk insta llment to attack the silk. When puts in order the Taiwan engine bed or the engine bed some pletely uses in pleting at the same time attacks the silk working procedure, widely uses has attacked the silk insta llment. Attacks the silk insta llment by to attack the silk headstock and to attack the silk to depend on the die head to be posed, because the profile nut and the profile pole are after rubs truncates and matches grinds, its pitch request with must process the spiral hole the pitch to ma inta in the certain relations, and is equipped with the pitch error to pensate the organization. Therefore uses attacks the silk insta llment to carry on attacks the silk to be possible to achieve the high precision. 6 aggregate machinetools cooling system The engine bed refrigera nt besides gets up the cooling effect to the cutting tool and the work piece, but also can form the lubr ication thin film in the meta l surface, gets up to the lubr ication. In some refrigera nts includes the sodium carbonate, the sodium nitrite and so on guards against rust the med icina l preparation, they form the porodine adsorption membrane or the oxide pound thin film in the meta l surface, also can cause the meta l to exempt the function which corrodes. Thus time choice refriger ant, should plete the craft, the processing method, the cutting tool materia l as well as is processed the ponents according to the aggregate machinetool the 4 徐州 工 程 學(xué) 院 畢 業(yè) 設(shè) 計(jì) (論文 )materia l to decide. Casts the iron stock when the processing, because cast irons itself includes the graphite to be able own lubr ication, all does not add the refrigera nt genera lly. In mass productions sometimes in order to reduce in the processing the powdered iron to fly upwards, also increases the cooling system, by improves the operating condition. Sometimes ma y use the soda water, 5% emulsion, its emulsifier principal constituent ma y be oxidizes the grease or the sulfurized oil. Its formula is: The grease 2% ~ 5%, the rough machining takes the low value, the precision work takes the high value。 B) jig peaceful process. basic loca lization principle analyzes here to discuss in 6 loca lizations, 6 degrees of freedom eliminations, in order to discovers the appropriate loca lization to cla mp the pla n. An object ma y have 6 independent movements in the space, namely along X, Y, the
