May see, the main neck or Lian Jing the turning working procedure all separates with the grinding working procedure, is often middle arrangement some different machined surfaces or the heterogeneity working procedure. After the rough machining can have the distortion.Thick, the precision work separates, and arranges the alignment working procedure behind the cutting force big working procedure, guarantees the processing precision. In order to reduce the distortion which the cutting force causes, guaranteed when precision work precision request, correct grinding various journals, uses the single grinding wheel in turn grinding generally. The journal processing requests high, the main neck and the neck uses continually processes many times. 2 Crank machining development direction Along with our country numerical control engine bed unceasing increase, the crank rough machining will be widespread uses in the numerical control lathe, the numerical control the milling machine, the numerical control vehicle broaching machine and so on the advanced equipment to the main journal, the connecting rod journal carries on the numerical control turning, in the milling, the vehicle - broaching nts 2 processing, by will effectively reduce the amount of deformity which the crank will process. The crank precision work will be widespread uses the CNC control the crankshaft grinding to carry on the correct grinding processing to its journal, this kind of grinder will provide grinding wheel automatic function requests and so on transient equilibrium installment, center rest automatic tracking unit, automatic survey, self-compensating system, grinding wheel automatic conditioning, permanent link speed, will guarantee the grinding quality the stability. In order to satisfy the processing request which the crank enhances day by day, set the very high request to the crankshaft grinding. The modern crankshaft grinding except must have the very high static state, the dynamic rigidity and outside the very high processing precision, but also requests to have the very high grinding efficiency and more flexibilities. In recent years, requested the crankshaft grinding to have the stable processing precision, for this, had stipulated to the crankshaft grinding process capability coefficient Cp1.67, this meant requested the crankshaft grinding the actual processing common difference to have the common difference which assigned compared to the crank small one half. Along with the modern actuation and the control technology, the survey control, CBN (cubic boron nitride) the grinding wheel and the advanced engine bed part application, for the crankshaft grinding high accuracy, the highly effective abrasive machining has created the condition. One kind calls it the connecting rod neck follow-up grinding craft. Has manifested these new technical synthesis application concrete achievement. This kind of follow-up grinding craft may obviously enhance the crank connecting rod neck the grinding efficiency, the processing precision and the processing flexibility. When carries on the follow-up grinding to the connecting rod neck, the crank take the main journal as the spool thread carries on revolving, and clamps the grinding all connecting rod neck in an attire. In the grinding process, the wheelhead realization reciprocation swing feed, tracks the biased rotation connecting rod neck to carry on the abrasive machining. Must realize the follow-up grinding, X axis besides must have the high dynamic performance, but also must have the enough tracking accuracy, guarantees the shape common difference which the connecting rod neck requests. The CBN grinding wheel nts 3 application realizes the connecting rod neck follow-up grinding important condition. Because the CBN grinding wheel resistance to wear is high, in the grinding process medium plain emery wheel diameter is nearly invariable, a conditioning may the grinding 600800 cranks. The CBN grinding wheel also may use the very high grinding speed, may use generally on the crankshaft grinding reaches as high as the 120140m/s grinding speed, the grinding efficiency is very high. 3 Connecting rod processing method The connecting rod decomposes (also called connecting rod breaks) the technical principle uses the material break theory, first artificial has the whole forging connecting rod semi finished materials big end of hole the fissure, forms the initial break source, then expands with the specific method control fissure, achieved the connecting rod The decomposition processing process enable the decomposition the connecting rod cap, the pole adjoining plane to have the complete meshing jig-saw patterned structure, guaranteed the adjoining plane precise docking, tallies, does not need to carry on the adjoining plane again the processing, simultaneously simplified the connecting rod bolt hole structural design and the whole processing craft, has the processing working procedure few, the economical precision work equipment, the nodal wood energy conservation, the product quality high, the production cost low status merit. Main body and the connecting rod cap separate goal. 4 Trend of development At present, the drop for and the die casting connecting rod host, the important status, are facing the powder to forge the steel connecting rod and a powder agglutination steel connecting rod forming craft challenge. Speaking of the domestic present situation, although the powder metallurgy forging industry had certain development, but must provide the mass and the high grade powder metallurgy forging is not mature. Moreover involves the equipment to renew, aspect expense questions and so on technical change, in next one, in long time, domestically produced connecting rod production also by drop forging craft primarily. The connecting rod is one of internal combustion engine main spare parts, its nts 4 reducing socket two sizes and the shape position errors have many requests, for example: Diameter, roundness, cylindricity, center distance, parallelism, hole and end surface verticality and so on. How does these erroneous project produce the scene in the workshop to examine, always is in the internal combustion engine profession a quite difficult question. In the connecting rod production, domestic mainly has following several examination method at present: With the spindle survey, namely puts on the spindle in connecting rod two, with the aid of in V shape block, plate, dial guage survey. Because the spindle needs to load and unload, therefore between the hole axis has the gap, the measuring accuracy is very low. 5 Crankshaft design requirements and working conditions Crankshaft is in constant cyclical changes in the gas pressure, reciprocating and rotating motion of the inertial force and the quality of their work under the joint action of the moment, so that both the torsion and bending the crankshaft, resulting in fatigue, stress state; internal imbalance of the engine crankshaft also withstand bending moment and shear force; not taken measures to make the crankshaft torsional vibration damping effect may also be a large amplitude torsional elastic torque. These loads are cross degeneration, may cause fatigue failure of the crankshaft. Practice shows that the bending has a decisive role in bending fatigue failure is the main failure modes. Therefore, the structural strength of the crankshaft bending fatigue strength is the focus, the crankshaft is designed to be committed to improving the fatigue strength of the crankshaft. Crankshaft complex shape, stress concentration is very serious, especially in the connecting rod journal and the crank arm of the fillet and lubricants at the stress concentration near the exit hole is particularly prominent. Common crankshaft fracture, fatigue crack begins with fillet and the hole place. Root bending fatigue cracks in the surface of the fillet from the journal at the development of the crank, the crank is basically broken into 450; torsion fatigue damage is usually bad from the machining start hole edge, about 450 cut into the crank pin. Therefore, in the design nts 5 of the crankshaft, pay special attention to finding ways to ease stress concentration, strengthen the stress concentration. Crankshaft journal at a very high ratio of pressure to a large relative velocity of sliding friction in the bearings in place. The bearings in the actual operation conditions changed conditions does not always guarantee a liquid friction, especially when the oil is not clean, the journal was a strong abrasive wear surface, making the actual life of the crankshaft greatly reduced. Therefore, the design, to wear to the friction surface, and the appropriate material-bearing Crank in the crankshaft is the central link, the stiffness is very important. If the crankshaft bending stiffness, then the possible occurrence of more severe bending, the piston rod and bearing deterioration in working conditions greatly affect the reliability of these parts work and durability, even the crankcase is too large and the local stress cracking. Crankshafts torsional stiffness is poor, the working speed range may be a strong torsional vibration. Ranging from noise, such as transmission gear on the crank to accelerate the wear; while in the crankshaft fracture. Therefore, the design should ensure-highest. As the crankshaft by the power complex, geometric cross-section shape is rather special, in the design, has yet to reflect the objective reality of a theoretical formula for Universal. Therefore, the current design of the crankshaft design relies mainly on experience. nts 1 曲轴加工的技术要求及发展方向 1 曲轴加工的技术要求 曲轴的技术要求是很高的,其机械加工工艺过程随生产纲领的不同和曲轴的复杂程度而有很大的区别,但一般均包括以下几个主要阶段:定位基准的加工;粗、精车和粗磨各主 轴 颈及其它外圆;车连 杆轴 颈;钻油孔;精磨各主 轴 颈及其他外圆;精磨连颈;大、小头及键槽加工;轴颈表面处理;动平衡 ;超精加工各轴颈。 可以看出,主 轴 颈或连 杆轴 颈的车削工序都与磨削工序分开,往往中间安排一些不同的加工面或不同性质的工序。粗加工后会发生变形,因此常把粗、精加工分开,并在切削力较大的工序后面安排校直工序,以保证加工精度。 为了减小切削力所引起的变形,保证精加工的精度要求,精磨各轴颈时,一般采用单砂轮依次磨削。 轴颈的加工要求高,主 轴 颈和连 杆轴 颈采用多次加工 。 2 曲轴机加工发展方向 随着我国数控机床的不断增加, 曲轴粗加工将广泛采用数控车床、数控内铣床、数控车拉床等先进设备对主轴颈、连杆轴颈进行数控车削、内铣削、车 -拉削加工,以有效减少曲轴加工的变形量。曲轴精加工将广泛采用 CNC 控制的曲轴磨床对其轴颈进行精磨加工,此种磨床将配备砂轮自动动平衡装置、中心架自动跟踪装置、自动测量、自动补偿装置、砂轮自动修整、恒线速度等功能要求,以保证磨削 质量的稳定。 为满足曲轴日益提高的加工要求,对曲轴磨床提出了很高的要求。现代曲轴磨床除了要有很高的静态、动态刚度和很高的加工精度外,还要求有很高的磨削效率和更多的柔性。近年来,更要求曲轴磨床具有稳定的加工精度,为此,对曲轴
