Abstract

涉及到夹具的薄壁小齿轮加工夹具,其外部为圆形,上面有一凹槽,内部有与薄壁小齿轮的齿数及薄壁小齿轮的齿轮轮廓相匹配的内孔。本实用新型能保证加工后的薄壁小齿轮与加工前的薄壁小齿轮参数相同,及齿轮节圆与加工面同轴度,并能杜绝齿顶夹伤、内孔变形、公法线变化等。

Description

薄壁小齿轮加工夹具
技术领域
[0001] 本实用新型涉及到夹具。
背景技术
[0002] 薄壁小齿轮进行机械加工过程中,除了加工齿轮轮廓外,还要对其他部位进行加工,在对其他部位进行加工时,如果装夹齿轮的齿顶,夹紧油压大则夹伤齿顶,夹紧油压小则打滑。如果采用普通节圆夹具夹三段齿根,容易使齿轮公法线变化,造成质量事故。
发明内容
[0003] 本实用新型的目的在于提供:薄壁小齿轮加工夹具,它是一种与薄壁小齿轮相匹配的齿轮轮廓节圆夹具。
[0004] 本实用新型的技术方案为:
[0005] 本实用新型的外部为圆形,上面有一个凹槽,内部为与薄壁小齿轮齿数及薄壁小齿轮的齿轮轮廓相匹配的内孔。
[0006] 本实用新型的优点如下:
[0007] 1、本实用新型能杜绝薄壁小齿轮的齿顶夹伤、内孔变形、公法线变化、齿面损伤等;
[0008] 2、本实用新型可保证加工后薄壁小齿轮的齿轮参数与加工前薄壁小齿轮的参数相同,并保证齿轮节圆与加工面的同轴度。
附图说明
[0009] 图1为本实用新型结构示意图;
[0010] 图2为图1的剖视图;
[0011] 图3为图1装夹图。
具体实施方式
[0012] 参见附图实施例,对本实用新型作进一步说明。
[0013] 图1-2中:夹具3的外部为圆形,上面有一凹槽6,内部有与薄壁小齿轮4的齿数及薄壁小齿轮4的齿轮轮廓相匹配的内孔5。
[0014]图3中:将一套9个夹具3用橡皮筋在凹槽6内圈好,再将夹具3夹住薄壁小齿轮4,再用弹簧夹头夹住夹具3,最后用机床的卡盘I装夹弹簧夹头2,即可对薄壁小齿轮4的其他部位进行加工。
