Description

齿轮孔整形推刀
技术领域
本实用新型涉及一种刀具,特别是指一种齿轮孔整形推刀。 
背景技术
油泵齿轮孔由于精度要求较高而形状结构也较为特殊,毛培采用粉末冶金成型,在压制后烧结时难免产生变形,因此成型后该孔往往达不到使用的精度要求,采用传统的加工成本较为高昂。 
实用新型内容
一、要解决的技术问题 
本实用新型的目的是针对现有技术所存在的上述问题,特提供一种齿轮孔整形推刀,有效的解决了,齿轮孔加工难度大,加工不便,加工成本较为高昂的缺陷。 
二、技术方案 
为解决上述技术问题,本实用新型提供一种齿轮孔整形推刀,包括有刀具体;上述刀具体中部设置有若干刀片,上述刀具体一端为锥面结构,其与水平轴向的夹角为0.5°,上述刀具体上下两端开有凹槽。 
作为优化,上述刀片之间的间距为6mm。 
三、本实用新型的有益效果 
本实用新型的齿轮孔整形推刀结构简单,加工精度稳定,加工简便效率高, 刀具体一端的锥面结构具有良好的导向性。 
附图说明
图1为本实用新型的齿轮孔整形推刀的结构图。 
图2为本实用新型的齿轮孔整形推刀的截面图。 
图中,1为刀具体,2为刀片,3为凹槽。 
具体实施方式
下面结合附图对本实用新型的齿轮孔整形推刀作进一步说明: 
实施例:如图1至2所示,本实用新型的齿轮孔整形推刀包括有刀具体1;上述刀具体1中部设置有若干刀片2,上述刀具体1一端为锥面结构,其与水平轴向的夹角为0.5°,上述刀具体1上下两端开有凹槽3。 
上述刀片2之间的间距为6mm。 
本实用新型的齿轮孔整形推刀对齿轮孔进行加工时靠挤压和刮削完成加工,避免了由于加工余量不均造成的二次误差。 
本实用新型的齿轮孔整形推刀结构简单,加工精度稳定,加工简便效率高,刀具体一端的锥面结构具有良好的导向性。 
以上所述仅是本实用新型的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本实用新型技术原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本实用新型的保护范围。
