2、cturing industry adapts changes unceasingly, uses the pool of labor power effectively, and has the competitive power in global scales market. Key word: aggregate machine-toolThe aggregate machine-tool is based on general parts, according to the specific shape and work piece machining process of the
3、special components and fixture design, semi-automatic or automatic special machine. Editor this segment The aggregate machine-tool machining The aggregate machine-tool usually adopts the multiracial, knife, more processes, and multi-faceted or multistage and processing, production efficiency than ge
4、neral machine high several times or more. Due to the standardization and serialization general parts have, can according to need flexible configuration, can shorten the cycle of design and manufacture. Therefore, the combination machine has the advantages of low cost and high efficiency, in large, l
5、arge production is widely used, and the automatic production line can be used to composition. The aggregate machine-tool for processing general box or special shape of parts. Processing, work piece rotate, generally by the tool and work piece rotate movement and tools for the relative motion, to rea
6、lize in drilling, reaming, economic hole, reaming, boring, cutting and milling, and the processing thread and fiber-end surface etc. Some combination machine adopts clamping work piece machining head to rotate, feeding movement by the tool for, also can achieve some ax symmetrical parts (such as the
7、 flywheel, automobile rear half axle, etc.) of the circle and the process.Combination machine parts classificationGeneral parts according to the function can be divided into power components and parts, transmission parts, supporting the control and auxiliary parts. Power components are provided for
8、The aggregate machine-tool in the movement and moving parts. Main motivation, cutting head and dynamic slide.Supporting components are installed power to slide into to institutions, cutting head or fixture, have side base, base, support, adjustable bracket, column and column base, etc.Transmission p
9、arts is used to transport or spindle box to the processing of the main parts, workstation dividing rotating table, the annular dividing rotating table, drum and to-and-fro moving workbench, etc.Control components are used to control the machine parts, automatic working cycle is hydraulic pressure st
10、ation and electrical cabinets and control console, etc. Auxiliary parts are lubrication device and cooling device and scraps discharge device etc.The development of modular machine toolIn order to make the aggregate machine-tool in small batch production, often applied to the structure, the applicat
11、ion of group technology and craft of similar parts in a centralized modular machine tool, in order to improve the machining efficiency. This machine has two kinds of common, spindle box The aggregate machine-tool and turn tower The aggregate machine-tool.The aggregate machine-tool of future developm
12、ent will be more adopts stepless motor and transmission of ball screw, etc, to simplify structure and shorten the production beat, Using digital control system and spindle box, jig automatic replacement system, in order to improve the process adjustability, Flexible manufacturing systems and into.Th
13、e aggregate machine-tool is take the general part as a foundation, matches by presses the work piece specific shape and the processing technological design special-purpose part and the jig, the composition semiautomatic or the automatic special purpose machine. The aggregate machine-tool selects the
14、 method which generally multiple spindle, the multi-knives, the multi-working procedures, many or the multi-locations simultaneously process, production efficiency ratio general engine bed high several times to several dozens times. Because the general part already the standardization and the serrat
15、ion, might according to need to dispose nimbly, could reduce the design and the manufacturing cycle. The multi-axle-boxes are aggregate machine-tools core parts. It selects the common parts, carries on the design according to the special-purpose request, in the aggregate machine-tool designs 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
