Description
技术领域
本发明涉及排屑方便的深孔加工方法。
背景技术
在构架加工中经常有长径比超过1∶5甚至达到1∶10的深孔。这些深孔的直径小,一般在20MM左右。如各种城轨车的单元制动孔。目前的深孔加工,采用G83式的深孔循环,现场加工中,到了深孔加工工序,钻头缠屑、挤屑、折断事故时有发生。加工上述深孔一度成为工艺人员头疼的问题,操作者只能在加工过程中停台进行手动定期排屑,这种辅助时间严重影响加工效率。
发明内容
本发明所要解决的技术问题是提供一种钻深可变式断排屑深孔循环,解决深孔内部的挤屑问题,延长钻头的使用寿命,提高加工效率。
为解决上述技术问题,本发明提供一种钻深可变式断排屑深孔加工方法,其特征在于包括下列步骤:
步骤102:指定深孔钻削变量,对深孔钻削涉及的变量进行赋值,赋值正确,进入步骤103,赋值不正确,则进入报警步骤104,重新赋值;
步骤103:钻第一孔深;
步骤105:判断钻深坐标是否大于钻深终点坐标,大于则进入步骤106,小于则进入步骤109,完成最后钻深,步骤110结束;
步骤106:判断钻深是否大于定义的断屑深度,大于则进入步骤107,断屑加工;小于则进入步骤111;
步骤111:加工至本次钻深,并返回安全位置进行排屑;
步骤112:判断本次钻孔深度是否大于最小钻深,大于则进入步骤113;小于则进入步骤114指定为最小钻深,进入步骤108;
步骤113:按照指定钻深比例进行递减,进入步骤108;
步骤108:计算下一次钻深坐标,返回步骤105进行判断。
本加工方法在深孔钻削时,将深孔钻削深度分为若干段,每一段均将断屑及排屑动作结合起来,在一定的钻深范围内采用断屑,超出这个范围进行排屑,从而保持铁屑始终顺畅排出,提高效率,又保证钻削的安全。
附图说明
附图是本发明的流程图。
具体实施方式
参照附图,步骤102,对深孔钻削涉及的变量进行赋值,包括安全高度、进给速度、第一次钻深、钻削起始位置、钻削终点位置、钻深递减比例、最小钻深,按照指定的第一钻深进行钻孔。指定钻深递减比例的意义是:由于随着孔深的增加,断屑情况会越来越差,适当缩短钻深,有利于排屑的顺畅。指定最小钻深的意义是:当钻深缩短到一定值时,与断屑长度相近,此时再缩短钻深已无意义,故需指定最小钻深值,当达到此值时,就用恒定的钻深进行钻削加工。
步骤106,判断此次钻深是否大于定义的断屑深度,大于则进行断屑动作,小于则钻至此次钻深位置之后返回安全位置进行排屑。
步骤112,判断本次钻孔深度是否大于最小钻深,大于则按照指定钻深比例进行递减,小于则指定为最小钻深。
步骤108,定义下一次钻深坐标。
步骤105,判断此次钻深坐标是否大于钻削终点坐标,大于则转向步骤106进行判断,并钻孔;小于则钻至深孔钻终点坐标,完成整个深孔钻过程。
