1、ZS175柴油机机体三面钻削组合机床总体及夹具设计摘要：柴油机机体是大批量生产的零件，为了提高加工精度和生产效率，需要设计一种组合机床来改善柴油机机体的加工情况。本课题设计了一台用于ZS175柴油机机体三面钻孔的组合机床。全文共有两部分，组合机床的总体设计和夹具设计。首先是总体设计，采用单工位三面钻孔组合机床，其中有加工对象工艺性的分析，机床总体布局的确定，定位基准的选择，滑台型式的选择，切削用量和刀具的选择，机床的总体设计。其次是夹具设计，通过对被加工零件的全面分析，在夹具设计过程中，采用后面、左面、下面三面定位,左面和后面用定位销定位，下面用定
2、位条定位。上面用液压缸夹紧,右面用液压缸辅助夹紧；夹具体为框架式结构，有良好的刚性，使夹具能长期保持可靠的精度和稳定性。该组合机床不仅能保证加工精度，还能提高加工效率。整个机床布局合理，夹紧可靠，精度较高，使用操作方便，提高了工作效率，达到了设计要求。关键词：组合机床；夹具；钻削本设计来自：完美毕业设计网http://www.bysj520.com登陆网站联系客服远程截图或者远程控观看完整全套论文图纸设计客服QQ：8191040TheGeneralandJigDesignofTheModularMachineToolforthethree-side
