文档介绍：三孔双向卧式组合镗床夹具设计
摘 要
双向卧式组合镗床设计主要包括卧式单工位双面组合镗床传动系统图的设计和多轴箱设计、夹具、刀具导向装置的设计和夹紧装置的选择。卧式单工位双面组合镗床传动系统图的设计和多轴箱设计、夹具、刀具导向装置的设计和夹紧装置的选择是组合机床的主要组成部分，是保证加工精度的关键部件。它和机床的其它部分有着及其密切的联系。因此，要求组合机床必须具有良好的刚性和足够的夹紧力，以保证在整个加工过程中工件不产生位移。同时，满足工件加工的各项技术要求，要保证工件不允许的变形，提高生产率和降低生产成本，工艺性和实用性要好。
由加工零件的工艺条件为粗镗，因此采用两面同时镗削，不仅加工方便，而且生产效率较高，因此采用双面卧式组合镗床进行加工是合理的。
根据加工零件的加工特点，选择一面两孔作为定位基准，限制工件在加工时的六个自由度。为了确保定位精度和稳定性，采用底平面定位。定位销采用手动回转机构定位销，用支承板定位系统，它用油缸经过推杆和一系列杠杆实现定位销的插入和拔出。

ABSTRACT
CK-?Numerically-controlled machine tool headstock horizontal type two-sided combination boring lathes and jig design
ABSTRACT
The bidirectional horizontal-type combination boring lathe design mainly includes the horizontal-type single location two-sided combination boring lathe kinematic scheme the design and the multi-axle-box design, the jig, the cutting tool guide design and the clamp choice. The horizontal-type single location two-sided combination boring lathe kinematic scheme's design and the multi-axle-box design, the jig, the cutting tool guide's design and clamp's choice is aggregate machine-tool's key component, is guarantees the working accuracy the key component. It and engine bed's other parts has and the close relation. Therefore, the request aggregate machine-tool must have the good rigidity and the enough clamping force, guaranteed that the work piece does not have the displacement in the entire processing process. At the same time, satisfies the work piece processing each specification, must guarantee the work piece does not permit the distortion, raises the productivity and reduces the production cost. The technology capability and the usability is friends with. by the processing components' technological conditions is the thick boring, therefore uses at the same time both sides boring, not only processes conveniently, moreover the production efficiency i
