Abstract

本实用新型公开了这样一种缩口式铣刀,为解决已有硬质合金铣刀存在的连接件与刀杆连接处易断裂的问题,本实用新型采取所述刀杆(1)通过呈曲面状的连接件(2)与所述刀头(3)连接或采取所述刀杆(1)一端设置成呈大小头圆台状,圆台小端通过呈曲面状的连接件(2)与所述刀头(3)连接。从而具有连接件与刀杆连接处不易断裂的优点。

Description

缩口式铣刀
技术领域
本实用新型涉及一种金属切削工具,尤其是涉及一种由刀杆和刀头组成的缩口式铣刀。 
背景技术
目前,市场上公开了这样一种铣刀,其结构特点是:由刀杆和刀头组成,刀头包括多条切削刃,在刀头一端和外表面上设置有多条切削刃,在刀头另一端通过呈大小头圆台状的连接件连接有刀杆,刀头通过连接件与刀杆连接成一个整体,在切削刃之间还设置有容屑沟槽。但,由于连接件与刀杆连接处应力较集中,易导致该处断裂,影响加工质量和生产效率。 
发明内容
本实用新型的目的是提供一种不易断裂,能提高加工质量和生产效率的缩口式铣刀。 
为达到上述目的,本实用新型缩口式铣刀,由刀杆和刀头组成,刀头包括多条切削刃,在刀头一端和外表面上设置有多条切削刃,在刀头另一端通过连接件连接有刀杆,刀头通过连接件与刀杆连接成一个整体,在切削刃之间还设置有容屑沟槽,所述刀杆通过呈曲面状的连接件与所述刀头连接。 
本实用新型缩口式铣刀还可以通过下述方案实现,所述刀杆一端设置成呈大小头圆台状,圆台小端通过呈曲面状的连接件与所述刀头连接。 
采用这种结构后,由于将刀杆通过呈曲面状的连接件与所述刀头连接,或将刀杆一端设置成呈大小头圆台状,圆台小端通过曲面与所述刀头连接,从而有效减少了应力集中,进一步提高了刀具的使用寿命,确保了加工质量和生产 效率。 
附图说明
下面结合附图和实施例对本实用新型作进一步的详细说明。 
图1是本实用新型缩口式铣刀的主剖视示意图。 
图2是本实用新型缩口式铣刀另一种实施方式的主剖视示意图。 
图中:1.刀杆  2.连接件  3.刀头。 
具体实施方式
图1所示本实用新型缩口式铣刀,由刀杆1和刀头3组成,刀头3包括多条切削刃,在刀头3一端和外表面上设置有多条切削刃,在刀头3另一端通过连接件2连接有刀杆1,刀头3通过连接件2与刀杆1连接成一个整体,在切削刃之间还设置有容屑沟槽,所述刀杆1通过呈曲面状的连接件2与所述刀头3连接;图2所示是本实用新型缩口式铣刀另一种实施方式,所述刀杆1一端设置成呈大小头圆台状,圆台小端通过呈曲面状的连接件2与所述刀头3连接。
