Abstract

本实用新型公开了一种剃齿刀,尤其是一种圆盘形剃齿刀,它包括有剃齿刀本体、剃齿刀内孔、键槽。所述剃齿刀内孔中部开有消气槽。所述消气槽的直径比剃齿刀内孔直径大2mm至4mm。这样的结构设计极大地提高了剃齿刀内孔和端面与剃齿机心轴的配合和定位精度,提高了剃齿刀剃削齿轮精度。

Description

剃齿刀
技术领域
本实用新型涉及一种剃齿刀,尤其是一种圆盘形剃齿刀。
背景技术
现在标准剃齿刀(如国标GB/T 14333-93) ,其定位内孔为直通孔,在内孔加工过程中,内孔的两端不可避免地会出现喇叭口,而内孔的中间段凸出,当剃齿刀剃装在齿机心轴上时,很容易出现剃齿刀内孔轴线和剃齿机的心轴轴线交叉的现象,即剃齿刀端面与剃齿机心轴不垂直,因此直接影响剃齿的精度,尤其是孔长的径向剃齿刀影响更大。若采用高级机床或特殊方法来解决这个问题,会增加设备费用和生产成本。因此基于上述原因,需要对剃齿刀的自身结构进行改进,从而提高内孔的定位精度和齿轮剃削精度。
实用新型内容
本实用新型所要解决的技术问题在于克服上述问题,而提供一种具有良好的定位精度和齿轮剃削精度的圆盘形剃齿刀。
本实用新型的目的是通过下列技术方案来解决的:
一种剃齿刀,包括有剃齿刀本体、剃齿刀内孔、键槽,其特征在于:所述剃齿刀内孔中部开有消气槽。
所述消气槽的直径比剃齿刀内孔直径大2mm至4mm。
本实用新型的有益效果是:采用上述方案对剃齿刀进行改进,在内孔中部增加消气槽,将内孔的中凸部分去掉,极大地提高了剃齿刀内孔和端面与剃齿机心轴的配合和定位精度,提高了剃齿刀剃削齿轮精度。
附图说明
图1为本实用新型一个实施例的主视图。
图2为图1所示实施例的左视图。
具体实施方式
现结合附图对本实用新型作进一步的说明:
如图1所示,本实用新型为一种剃齿刀,它包括有剃齿刀本体1、剃齿刀内孔2、键槽4。剃齿刀本体1呈圆盘形,在圆盘形上,外面齿形为切削工作部分,齿形的两侧梳有小槽,形成刃口和容屑槽,齿根部有小孔5,方便齿形两侧梳小槽。中间是剃齿刀内孔2,剃齿刀内孔2中部开有消气槽3,剃齿刀内孔2边上设有鍵槽4。消气槽3的宽度C是根据剃齿刀的厚度B而定,剃齿刀厚度B越大,消气槽3的宽度C就越宽,消气槽3的直径φ1比剃齿刀内孔直径φ大2mm至4mm。
本实施例中,剃齿刀内孔直径φ为63.5mm,剃齿刀厚度B为25mm,消气槽直径φ1为66.5mm,消气槽宽度C为8mm。
本实用新型可在车加工时车出孔中部的消气槽,也可在孔精加工成型后,再磨出消气槽。

Claims (2)

1.一种剃齿刀,包括有剃齿刀本体、剃齿刀内孔、键槽,其特征在于:所述剃齿刀内孔中部开有消气槽。
2.按照权利要求1所述的,其特征在于:所述消气槽的直径比剃齿刀内孔直径大2mm至4mm。
