【文章內(nèi)容簡介】 improve the process adjustability, Flexible manufacturing systems and into. 7 The aggregate machinetool is take the general part as a foundation, matches by presses the work piece specific shape and the processing technological design specialpurpose part and the jig, the position semiautomatic or the automatic special purpose machine. The aggregate machinetool selects the method which generally multiple spindle, the multiknives, the multiworking procedures, many or the multilocations simultaneously process, production efficiency ratio general engine bed high several times to several dozens times. Because the general part already the standardization and the serration, might according to need to dispose nimbly, could reduce the design and the manufacturing cycle. The multiaxleboxes are aggregate machinetool39。s core parts. It selects the mon parts, carries on the design according to the specialpurpose request, in the aggregate machinetool design39。s process, is one of work load big parts. It is acts according to the work piece processing hole quantity which and the position the working procedure chart and the processing schematic drawing determined, the cutting specifications and the main axle type design transmission various main axles movement power unit. Its power from the general power box, installs together with the power box in to feed sliding table, may plete drills, twists and so on working processes. This topic designed has used in the top head hole processing the drill hole aggregate machinetool. According to the top head hole ponents size which must process carries on the aggregate machinetool general multiaxleboxes the design, draws up the multiaxlebox primitive basis chart, the definite main axle and the gear modulus, determined the transmission system, calculates the main axle and drive shaft39。s coordinate. Through the above design, realized a top head onesided six processing to plete, has achieved the design requirements well。 To meet the bination of CNC machine tools of development, it is a ponent of the NC machine tool NC module. Portfolio machine is modular bination of CNC machine tools brought about by the inevitable result is the bination of CNC machine tools necessary foundation, NC module so greatly enriched the portfolio of generic pieces of machine tools, it will cause bination of General Machine Type of a fundamental change. NC modules, according to their coordinates NC (axis) of mainly single coordinates, dual coordinates and coordinates. Its spindle number, single and multiaxis module, there are single and multiaxis 8 posite processing module. NC module development, there are mainly two kinds of ways: First, the existing the aggregate machinetool tools should be relatively mon items, the NC General of the design. At present there is also domestic NC is developing onedimensional slider, NC twodimensional (Cross) Waterloo Taiwan, the NC rotary table, all this is the way the NC is based on the characteristics of the development of NC The unique the aggregate machinetool tool parts, such as automatic replacement of multiaxis spindle box, the NC rotary knife, NC for the manipulator, NC for me, such as mechanical hand. The past 10 years, machine tools and automatic line group in the highly efficient, high productivity, flexibility and the use of parallel (synchronous) works develop more reasonable and more savings in the programmed has made a lot of progress. In particular the automobile industry, in order to improve the performance of motor vehicles, precision machining of ponents made a number of new demands, so the machine performance requirements are also higher. In recent years, with numer
