动平衡减振切割机结构设计

Structure Design of Damping Incision Machine in the Condition of Dynamic Balance

针对切割机在工作过程中出现的机身颤振所引起的切割定位跑偏问题,对其结构进行二次设计,解决整机在工作状态下的定位精度问题。利用动平衡原理,采用对称结构的双刀片立式机身结构,抵消由动力源传递给单一切割片所引起的不平衡力,使机身在工作状态下达到一定程度的动平衡。此外选用磁性底座对金属切削材料实现磁吸附式的定位切割,达到吸振减振、提高定位精度的目的。

For the problem of orientation precision off tracking of incision machine caused by its vibration in the condition of work state, the structure is redesigned for improving the cutting precision. Dynamic balance principle and symmetry configuration are applied for eliminating imbalance and achieving dynamic on the sense. In order to improve orientation precision, magnefic base is used for absorbing metal cutting material.
