Abstract

一种套孔钻刀具，包括套孔钻，其特征在于，套孔钻前端设置有左右对称的两个容积空间。本实用新型套孔钻刀具在实际使用中，证实有效地解决了大多套孔钻刀具所不能解决的取样不十分精准，屑不能顺畅排出，切削液和压力风无法到达刀头，切削温度无法排出的问题，得到了用户的好评，取得了良好的经济效益和社会效益。

Description

套孔钻刀具
技术领域
本实用新型涉及一种套孔钻刀具，属于机械领域。 
背景技术
对于现有技术，原专业厂商提供的套孔钻外径60毫米只能取120毫米深的试样，不能达到135毫米取样要求，而且取料后留在材料上的直径达60毫米。原因：（1）套孔钻设计上排屑槽及容积空间过小。（2）使用可转位刀片尺寸过大，切削力也增大，切削温度随之增大（3）切屑不能顺畅排出，切削液和压力风无法到达刀头，切削温度无法排出，并且切削温度大多集中在刀头上，造成刀体端头材料软化，无法深孔加工，给生产生活带来了极大的不便。 
发明内容
本实用新型的目的是提供水管，以克服现有技术的不足。
为了实现上述目的，本实用新型采用如下技术方案：
一种套孔钻刀具，包括套孔钻，其特征在于，套孔钻前端设置有左右对称的两个容积空间。 
优选地，套孔钻的两个侧面各设置有两个缺口，两个缺口之间设置一条槽且与前端容积空间联成一体，其目的是，增大容积空间，便于切削液和压力风进入，提高排屑能力和降低切削与孔壁的摩擦。
   本实用新型套孔钻刀具在实际使用中，证实有效地解决了大多套孔钻刀具所不能解决的取样不十分精准，屑不能顺畅排出，切削液和压力风无法到达刀头，切削温度无法排出的问题，得到了用户的好评，取得了良好的经济效益和社会效益。
附图说明
图1为本实用新型套孔钻刀具结构示意图；
图中标号：1-容积空间，2-缺口I，3-缺口II，4-槽。
具体实施方式
为了加深对本实用新型的理解，下面将结合实施例和附图对本实用新型作进一步详述，该实施例仅用于解释本实用新型，并不构成对本实用新型保护范围的限定。
一种套孔钻刀具，包括套孔钻，其特征在于，套孔钻前端设置有左右对称的两个容积空间1，套孔钻的两个侧面设置各设置有有缺口I2和缺口II3，缺口I2和缺口II3之间设置一条槽4且与前端容积空间1联成一体，增大容积空间，便于切削液和压力风进入，提高排屑能力和降低切削与孔壁的摩擦；选用尺寸较小的可转位刀片，减小切削力，并且所掏孔直径较小，有利于今后零部件加工余量的留取。

Claims (2)

1.一种套孔钻刀具，包括套孔钻，其特征在于，套孔钻前端设置有左右对称的两个容积空间。
2.如权利要求1所述的套孔钻刀具，其特征在于，套孔钻的两个侧面各设置有缺口I和缺口II，缺口I和缺口II之间设置一条槽且与前端容积空间联成一体。
