数控转台锁紧机构的设计与计算

Design and Calculation of Locking Mechanism of NC Rotary Table

数控转台能够为机床提供回转坐标,增加加工维度,是一种重要的功能部件。从分度转台定位和连续转台定位两方面对数控转台锁紧机构进行设计和计算。对于分度转台定位,进行了齿盘强度校核。对于连续转台定位,设计了摩擦片式夹紧机构和环抱式夹紧机构。

The NC rotary table can provide rotary coordinate for the machine tool and increase the processing dimensionality,and it is an important functional component.The locking mechanism of NC rotary table was designed and calculated from two aspects i.e.indexing positioning and continuous positioning.For indexing positioning of the rotary table,the strength of the fluted disc was checked.For continuous positioning of the rotary table,a friction disc clamping mechanism and an embracing clamping system were designed.
