清华的GG,你翻译的不错,但我相信分会给我的,呵呵Frame Shaper, planer and the other with a vertical movements of the machine tool holder existed a turret knife problem. We demand strict accordance with the carrier transmission ratio decreased, but in fact Tool moment more often in decline for some distance, sometimes simply not screw rotation, vibration, tool carrier under Chong for some distance. . This turret suddenly the whereabouts of the phenomenon is most common "tool carrier knife." Tool cutter knife makes a sudden increase in the depth of cut, causing fracture tool The content is as follows, please press this form translation 4. prevented the tool rest falls the knife installment B665 , Dragon Gate digs the bed and other has the vertical fluctuation tool rest the engine bed to have a tool rest to fall the knife the question. We request the tool rest strictly to drop according to the velocity ratio, but the tool rest often dropped section of distances in fact in the flash, sometimes the lead screw simply has not rotated, because vibrates, under the tool rest flushes section of distances. This kind of tool rest sudden whereabouts phenomenon, is we common "the tool rest falls the knife". The tool rest fell the knife to cause the cutting tool suddenly to increase the depth of cut, created the cutting tool break, the work piece discards, even caused the accident. The reason of knife fallen is the lead screw nut transmission has gap. When the vertical tool rest drops,as the friction force hinders it's drop, which causes the lead helicoid come into contact with the under helicoid. Then the lead screw nut gap in under, and now the nut dose not entrsuat the lead screw as well as the entire tool rest, as a result of friction drag function it will not whereabouts. Because the tool rest gravity, the tool rest guide rail contact situation is dissimilar in the span, the friction drag is different, in addition engine bed vibration factor and so on , in some as soon as flickers asked, the tool rest has overcome the friction drag control, suddenly under flushes, until lead helicoid come into contact with the under helicoid,all parts of tool rest's weight will be entrusted by nut.. Chart 5 prevented the tool rest falls the knife installment 1 lead screws 2 nuts 3 bolts 4 springs 5 spring holders 6 turntables The common method to increase the friction force is tightening the clamping screw or adjusts the tight guide rail to fill hard the method, prevented the tool rest falls the knife, but it cannot permanently cure, and operate troublesomely, the engine bed attrition intensifies, specially the guide rail center-section uses comparatively much, it is easy to form a scoop channel to cause the gap to increase, and knife fallen phenomenon increase. Therefore, we can make some improvements to the B665 tool rest structure (like chart 5 to show), 1 turned on lathe the original tool rest lead screw, turned on lathe into the nut 2, installed spring holder 5 and the spring 4, dismantled turntable 6 and drills a screw thread, turned on lathe into the clamping screw to subscribe 3, 6 and the tool rest part installed the turntable the original position, rotated the nut 2, regulating spring 4 tension, caused the tension to be equal to or slightly to be bigger than the tool rest part the gross weight, fastened with the bolt. Thus causes lead screw 1 on throughout with the turntable 6 on under spiral appearance contact, the lead screw nut gap at under, not to be able to create the tool rest suddenly under to flush falls the knife phenomenon. This improvement measure after production practice proof, method , the effect is good. 5. conclusions Through the above analysis, some questions which exists to the B665 tool rest, proposed the concrete improvement measure, separately narrated on increased the fluid in B665 to move the type automatically to lift the knife installment, automatical uprightness turnover framework, as well as the improvement tool rest partial structure, prevented "the tool rest fell the knife" the phenomenon. Above method after production practice proof, method simple, safe reliable, the effect is good.

4. Tool knife to prevent device Frame Shaper, planer and the other with a vertical movements of the machine tool holder existed a turret knife problem. We demand strict accordance with the carrier transmission ratio decreased, but in fact Tool moment more often in decline for some distance, sometimes simply not screw rotation, vibration, tool carrier under Chong for some distance. . This turret suddenly the whereabouts of the phenomenon is most common "tool carrier knife." Tool cutter knife makes a sudden increase in the depth of cut, causing fracture tool and workpiece scrapped, and even caused the accident. Have a knife because of a screw-nut drive space. When the vertical turret decline, due to friction hinder its decline, the screw on helical screw nut under the physiognomy contact screw nut in the space below. Then screw nut did not try to jack up the entire turret components and the weight, the role without friction whereabouts. As the turret of gravity, the rail carrier of the contact is not the same length, ranging from friction, coupled with the machine vibration factors, in a twinkling asked turret overcome the frictional resistance of control, sudden impulse, the next until the screw and nut helical spiral on the surface contact, entrusted by the Nut live turret components of the weight. Figure 5 Prevention Tool knife devices A trace of a two-nut screw 4 3 1 5 1 1 Spring Spring Block 6 a turntable Commonly used methods of increasing friction, rotation set screws tightly or transfer tight track Cypriot iron approach to prevent turret knife, but it can not cure, and operational troubles, exacerbated machine wear, especially the middle guideway used more easily result in a groove so that gap increased knife on the increase. This can be right Cutter Shaper tool carrier for the local structure of the improvements (as illustrated in figure 5), a former turret rotating screw up, spin-Nut 2, spring loaded Block 5 and springs 4, 6 and turntable removed attacking a screw drill hole swirls into tight spiral set at 3, 6 turntable Tool components and put back into the original, two rotating nuts, adjusting the four elastic springs, elastic equal to or slightly larger than turret components, the overall weight, with solid screws tight. Thus the screw on a spiral surface always on the turntable within six under screw thread of contact with the outside, screw nut in the space below, the carrier will not cause a sudden drop under pressure from the knife phenomenon. The improvement measures proved by the production method is simple and effective. 5. Conclusion Through the above analysis, the right Frame Shaper tool holder of a number of issues, and put forward specific measures for improvement were described in the Frame Shaper increased hydraulic lift automatic knife, automatic vertical feed, as well as improved turret local structure to prevent "Tool knife" phenomenon. The above method proven by the production method is simple, safe, effective and reliable. 你看看吧！！ 肯定对 不是用软件翻译的 我是北大的 你呢？？ 英语系的

一般的情况下，英语老师都是从师范学校专门培训的，然后分配到各个学校补充教师队伍。像你这样，想自考英语专业的本科，以后当英语老师的可能性也存在的；关键是你先毕业，然后再去教育局咨询和报名。祝你梦想成真！
