摘要
机床端面驱动卡盘顶紧力过大会加重机床负荷以及工件弯曲变形,顶紧力过小工件容易脱落,顶紧力分析对端面驱动卡盘安全使用有着现实的意义。以自行设计的一种端面驱动卡盘为例,对所需顶紧力进行分析计算;通过对只计驱动销摩擦力、考虑驱动销微量嵌入工件以及机床振动所需顶紧力计算,得出不同工况下所需顶紧力的计算公式,并对不同工况下顶紧力公式进行实验验证,指导实际生产。
Since excessive tightening force of end drive chuck aggravates the load of machine tool and bending deformation of workpiece,while insufficient tightening force causes the workpiece easily to fall off,the calculation of the tightening force plays a significant role in safe use of the end drive chuck.With a self-designed end drive chuck as the example,analysis and calculation on top tightening force are carried out by sole caculation of driving pin friction force,and in considerations of micro embedding and machine tool vibration.The calculation formula required by tightening force under different working conditions are gained,which are verified by experiments to guide actual production.
