形状特殊的零件加工偏心孔的装夹方法

Clamping Method for Machining Eccentric Hole of Special Shape Part

介绍了一种特殊的零件在立车加工内孔五个偏心圆时,因偏心圆与中心圆圆心相差100~144 mm,也就是说装夹零件时卡盘爪已经夹不到基本圆中心上,因零件的几何形状限制,装夹部位高度只有35 mm,给找正带来很大困难和较大的安全隐患。经过钻心研制,打破了常规的装夹方法,自制副卡盘来装夹零件,找正时挪动副卡盘,即可保证装夹的稳定性,又提高了装夹精度,找正方便快捷。

Introducing a kind of special parts in vertical lathe machining inner hole five eccentric circle, due to the eccentric circle and the center park center have a difference of 100 - 144 mm. That is to say when the clamping parts jaw chuck have clip can not base circle center, due to the restrictions of the geometry of parts, the clamping part height only 35mm, to find is bringing great difficulty and greater security risks, after the discrepancies in the actual development, breaking the conventional clamping method, homemade vice chuck to clamp parts, find is when the mobile Deputy chuck, can guarantee the clamping stability, but also improve the clamping precision, find it convenient.
