文档介绍：摘要
本文是立式钻床用多轴头架设计,多轴头架各轴在圆周方向均布,固定式多轴头是根据一个典型法兰盘类零件而设计的,用于零件中大批量生产要求。
多轴头架的设计参数来源于一般的加工工艺条件,以适应更广阔的加工范围。针对工厂里多孔钻削时,孔径一般较小,多在20mm左右,而且大部分是箱体、法兰盘等,箱体、法兰盘多为铸造件,材料是铸铁,也有个别的被加工零件的材料是低碳钢。根据这些工件的切削条件,可以确定多轴头架的工艺主参数。
可以看出,改装后的多轴钻床,可以同时完成多个孔的钻、扩、铰等工序。工艺范围可以满足一般加工情况的孔类钻削要求。可调多轴头架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。参照该调节原理可进行其他任意孔系加工装置的设计,还可以用于攻丝、扩、锪孔等加工装置。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。

Abstract
The 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 the small scale production needs of the screw hole manufacture for flange plate the fixed multiple spindles heads is design for the big scale production needs of the screw hole manufacture for flange plate parts,it can’t be used to manufacture another farts, because it’s spindle distance is designed for the only part.
Because of the un-development in our manufacture industry ,pany’s plant lack of the machine to drill multiple holes at the same time , and it’s 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 pany to drill the multiple holes in a fast way .And pany gained the economic performance by the way of reequips the machine tools. It’s the fact that the reequipped drilling machine can satisfy the process precision requirement .so the design is feasible.
Key words:drilling machine adjustable multiple spindles heads
