【技术实现步骤摘要】
可调式内冷深孔镗排
本技术涉及机械加工
,尤其是一种可调式内冷深孔镗排。
技术介绍
机械加工中,对于工件上直径较大的孔一般采用镗削加工,如果孔长度又较长的话,镗削时需两头分别加工,加工过程中工件需经过掉头后两次装夹,这样对于孔的圆度、同轴度影响较大,镗孔效率也较低,可镗孔径受到局限。同时普通镗杆较细、刚性差且易变形,镗孔切削量小、速度慢,镗孔吃刀量较大时,刀具易受热磨损。
技术实现思路
本技术要解决的技术问题是:为了克服现有技术中之不足,本技术提供一种提高镗孔使用范围、一次性装夹即可完成工件深孔加工的可调式内冷深孔镗排。本技术解决其技术问题所采用的技术方案是:一种可调式内冷深孔镗排,具有中空的镗杆,所述的镗杆前端固定有端盖,端盖面上设有可沿镗杆径向移动调节的刀座,刀座上安装有可径向调节的车刀,镗杆后端设有使用时可在机床导轨移动的尾座,镗杆上套装有使用时由机床中心架支撑的定位套,镗杆后端面安装有可通入外界冷却水的水管接头,镗杆内水管接头连接的水管连通到车刀处。具体说,所述的刀座上开设有径向长孔,刀座通过刀座螺栓拧入端盖上的螺孔可调节地安装在端盖上;所述的车刀开设有径向长孔,车刀通过压刀螺栓拧入刀座上的螺孔可调节地安装在刀座上。进一步地,所述的尾座具有并排的两个支撑架,镗杆后端穿过所述支撑架,位于所述支撑架两侧分别安装有可满足不同直径镗杆使用的可调压盖。本技术的有益效果是:本技术采用可径向移动调节的刀座并同时采用可调节安装的车刀结构,扩大了可镗孔径范围,通过镗杆内 ...
