Abstract

本实用新型针对现有技术中钻头因其钻销部位易耗尽,而其装卡部位不易损耗,却与钻削部位一起报废的不足,提供一种组合式钻头,包括卡装部分和钻削部分,所述的钻削部分由钻头柄部和钻头头部一体式连接组成,所述的装卡部分为固定套装在所述的钻头柄部的钻头套,所述的钻头套设置有连接螺纹,本实用新型的钻头,由于装卡部位和钻削部位分开设置,所以当钻削部位耗尽时,只需报废钻削部位,而装卡部位可重复使用。

Description

组合式钻头
技术领域
本实用新型涉及一种钻头。
背景技术
现有的钻头,其装卡部位和钻削部位为一体式的,当其钻削部位消耗尽时,其装卡部位仍然完好,却要与钻削部位一同报废,这样会造成原材料浪费。
发明内容
本实用新型的目的在于,针对现有技术中钻头因其钻销部位易耗尽,而其装卡部位不易损耗,却与钻削部位一起报废的不足,提供一种装卡部位可以重复使用的组合式钻头。
本实用新型的目的是通过下述技术方案完成的:
一种组合式钻头,包括卡装部分和钻削部分,所述的钻削部分由钻头柄部和钻头头部一体式连接组成,所述的装卡部分为固定套装在所述的钻头柄部的钻头套,所述的钻头套设置有连接螺纹;
沿所述的钻头柄的中心轴设置有通向钻头头部的注水孔。
本实用新型的组合式钻头,由于装卡部位和钻削部位分开设置,所以当钻削部位耗尽时,只需报废钻削部位,而装卡部位可重复使用。
附图说明
图1是本实用新型实施例钻头结构示意图。
附图标记说明:
1-装卡部分  2-注水孔   3-钻削部分  4-钻头头部  5-钻头柄部  6-钻头套   7-紧定螺钉  8-连接螺纹
具体实施方式
下面结合附图和具体实施方式对本实用新型作进一步说明:
如图1所示,本实用新型的组合式钻头,包括装卡部分1和钻削部分3,装卡部分1和钻削部分3固定连接。较好的,钻削部分由钻头头部4和钻头柄部5组成,装卡部分1为套装在钻头柄部5的钻头套6,钻头套6和钻头柄部5可以通过卡装或者紧定螺钉7固定连接。沿钻头柄部5的中心轴设置有注水孔2,通向钻头头部4。钻头套6设置有连接螺纹8,用来与钻机连接。

Claims (2)

1.一种组合式钻头,其特征在于:包括卡装部分(1)和钻削部分(3),所述的钻削部分(3)由钻头柄部(5)和钻头头部(4)一体式连接组成,所述的装卡部分为固定套装在所述的钻头柄部的钻头套(6),所述的钻头套设置有连接螺纹。
2.如权利要求1所述的组合式钻头,其特征在于:沿所述的钻头柄的中心轴设置有通向钻头头部的注水孔。
