1、河南机电高等专科学校毕业设计说明书摘要根据加工的为法兰盘类零件的螺孔的设计要求，特设计此固定式四轴头架，用于零件中大批量生产。 设计主要包括传动系统图的绘制，多轴头架上齿轮几何尺寸计算、绘制多轴头总图、轴承寿命的计算，确定四轴头架的工艺主参数，进行四轴头架的总体设计。改装后的四轴钻床，可以同时完成四个孔的钻、扩、铰等工序。可以起到提高生产效率、降低成本、提高孔系加工精度等作用。此外该装置具有结构简单、操作方便、应用范围广等特点，值得推广。关键词：立式 钻床 四轴头 可调 齿轮河南机电高等专科学校毕业设计说明书Abstract The
2、design of multiple spindles heads for drilling machine whose drills spindles are adjustable or fixed are introduced . The adjustable spindles of the multiple spindles heads are located evenly in the circuit and can be adjusted synchronism on the diameter’s direction to meet
3、 the small scale production needs of the screw hole manufacture for flange plate parts.And the fixed multiple spindles heads is design for the big scale production needs of the screw hole manufacture for parts,it can’t be used to manufacture another farts, because it’s spin
4、dle distance is designed for the only part. The design of multiple spindles heads include three parts : the total design, the transfer system design , and the constructive design . Because of the un-development in our manufacture industry ,most company’s plant lack of the
5、machine to drill multiple holes at the same time ,a waste of funding on the manufacturing facilities which will be laid after the parts are produced . so the economic multiple spindles heads enable the normal company to drill the multiple holes in a fast way .And same com
6、pany gained the economic performance by the way of reequips the.It’fact that the reequipped drilling machine can satisfy the process precision requirement .so the design is feasible. Based on the design of the multiple spindles heads , we can also design the others to the
