双减速器消隙方法的精度分析与实验
|
摘要
对我国多主轴数控机床的使用现状进行了简介,分析出大批高效加工零件对多主轴机床的需求。受限于传统消隙方法,多主轴转台消隙装置仅作为中间级,无法提供功率输出,难以满足转台规模扩大后对紧凑性、传递效率、响应速度的需求。对此问题,提出了一种"双减速器消隙"的新型消隙方法。通过对这一消隙方法的理论精度分析与试验,证明此消隙方法能够达到(5～10)角秒的定位精度,传动效率、响应速度等指标均好于双蜗杆和双齿轮消隙方法,对小尺寸多主轴转台的研制具有一定的参考价值。
It introduces the current status of multi spindle CNC machine tools in China. The demand of multi spindle machines for high volume and high efficiency machining parts is analyzed,and then the rectangular array synchronous rotary table is distinguished from the conventional linear array multi spindle rotary table. The necessity and difficulty of development of rectangular array rotary table are analyzed. Aiming at the anti-gap of rectangular array rotary table with multi-spindle output,a method of "Double Reducer Anti-gap"is proposed. Through the theoretical accuracy analysis and test of this anti-gap method,the feasibility is analyzed. The results of the analysis has advantages for the development of small-size multi-spindle turntable reference value.
