内 容 摘 要
组合机床通常是指以通用件为基础，再依据具体工件的特定形状、特定的加工工艺要求，配以专用的夹具和主轴箱，组成的自动或者半自动专用机床。组合机床的使用越来越系列化、标准化，特别是通用件和专用件构成的多轴、多刀、多面及多工位一同加工的效率非常高的专机，它的产出率与通用型相比已有较大的提高，可完成钻、镗、铰、铣削等加工。组合机床现已发展为一类专用的、高效的自动化技术装备。在其构成中，通用件和标准件占到70-80%左右,它们都是系列化的,因而在大批量生产的机械工业部门，大量选用的设备是组合机床。其余20-30%的专用件是由被加工零件的形状,轮廓尺寸,工艺和工序等情况来决定的。
由于组合机床的设计过程是相当复杂的，因而在设计过程中要查阅相当多的机械方面的资料，但是又要考虑在加工过程尽量使加工简单，又不能影响加工的质量要求，而且应使各个工序能够集中，展现组合机床的独特优势。与此同时，要使加工过程中的各种误差减小到尽可能小的程度。
关 键 词
组合机床；多轴箱；夹具；误差

Abstract
Aggregate machine-tool usually refers to an automatic or semi-automatic special purpose machine composed by which is based on general part and equipped with special-purpose fixture and spindle box in accordance with the special shape of the specific spindle box and specific manufacturing requirement.The use of the aggregate machine-tool is more and more serialization and standardization,especially the specific machine tools with multi-axis,multi-knife,multi-working procedure,multi- surface and multi-station processing,which are composed by the common parts and a small number of special components.Its productivity improved significantly compared with common machine and it can be used
for
drilling,boring,
reaming,tapping,turning
and
milling
machine.Currently aggregate machine-tool has been developed into a kind of specialized and efficient automation equipment.The general parts and standard parts of the aggregate machine-tool accounted for 70-80%.These parts are serialized, so the aggregate machine-tool is widely used in the mass production machinery industrial sector.The
remaining 20-30% of the special parts is decided by the shape, dimensions,technology and processes of the processed parts.
Due to the complex design process of the aggregate machine-tool,we should refer to quite a number of mechanical information in the design process.but also should consider to make the process as simple as possible , and should not affect the quality of the processing requirements. And try to centralize each process and giving full play to the unique advantages of aggregate machine-tool. At the same time, we should ensure that all kinds of errors in the process should be reduced to the degree as little as possible.
Key Words
Aggregate machine-tool; Multi-spindle box; Fixture; Error
