1、连杆螺栓孔铰削专机总体及主轴箱设计摘要:本课题来自恒力集团，柴油机连杆是需要大量生产的零件。为了高速、高效的完成连杆螺栓孔铰削加工及保证相应的加工尺寸精度，本课题设计了一种专用于连杆螺栓孔铰削加工的组合机床。该机床设计的重点分总体设计和零部件设计两部分。总体设计包括对连杆进行工艺分析、确定专机的配置型式和工件定位、夹紧方案；对各种切削参数进行计算，从而确定动力箱电机功率以及完成“三图一卡”的设计。根据总体设计要求对主轴箱进行设计，主要包括绘制原始依据图、确定主轴和齿轮、完成动力计算、设计传动系统、绘制主轴箱装配图和零件补充加工图。该机床采用液压滑台

2、实现刀具进给，采用机械动力箱驱动各个主轴的旋转运动保证各个主轴的转向、转速等，借助导套引导刀具实现精度要求和稳定的铰削加工。本组合机床能满足加工要求，保证加工精度，机床运转平稳，工作可靠，结构简单，装卸方便，便于维修、调整。操作的简便，减轻了工人的劳动强度，提高了劳动生产率。关键词：组合机床；总体设计；铰孔；主轴箱设计本设计来自：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：8191040DesignofGeneralandHeadstockofModularMachi
