Abstract

本实用新型公开了一种排除丝锥断茬的有槽钻头。所述的钻头前段为直锥形并设置有槽。钻头上的槽宽度与断茬腹部厚度相当,将钻头装在钻床或镗床上,槽口放置在断茬腹部上后,反转钻头,即可将断茬取出。使用本架构的钻头能够在不破坏工件的情况下快捷方便的去除断茬。

Description

排除丝锥断茬的有槽钻头
技术领域
本实用新型涉及一种钻头,尤其是一种排除丝锥断茬的有槽钻头。 
背景技术
机械加工领域,经常需要对工件进行攻丝。对于有气孔或者粘度较大的金属工件攻丝时,往往产生丝攻折断的情况。出现丝攻折断的情况是件非常麻烦的事情。对于价值较低的工件,往往弃之不用。对于价值较高的工件,只有采取扩孔的办法取出断茬,这样既麻烦也破坏了工件的完整性。 
实用新型内容
本实用新型的目的是解决在不破坏工件的情况下快捷方便的去除断茬。 
本实用新型采用的技术方案是:将一个直经略小于断茬的钻头按后角磨成直锥,钻头上有一个宽度与断茬腹部厚度相当的槽,将钻头装在钻床或镗床上,槽口放置在断茬腹部上后,反转钻头,即可将断茬取出。 
本实用新型采用的有益效果是:使用本架构的钻头能够在不破坏工件的情况下快捷方便的去除断茬。 
附图说明
图1为本实用新型示意图。 
图中所示:1,钻头 2,槽 
具体实施方式
下面结合图1,对本实用新型做进一步的说明。 
如图1所示,一种排除丝锥断茬的有槽钻头,所述的钻头前段为直锥形并设置有槽2。钻头上的槽宽度与断茬腹部厚度相当,将钻头装在钻床或镗床上,槽口放置在断茬腹部上后,反转钻头,即可将断茬取出。使用本架构的钻头能够在不破坏工件的情况下快捷方便的去除断茬。
