一种高精度滚齿浮动夹具
:本技术涉及夹具领域,更具体的说是涉及一种高精度滚齿浮动夹具。
技术介绍
:目前滚齿产品精度要求普遍都很高,加工过程难度较大。外齿滚齿精度要求达到5~6级水平,并且加工过程容易变形,对于夹具设计尤其面临严峻考验,现有的滚齿夹具为螺母压紧式结构,在滚齿过程中,我们发现现有夹具存在如下缺陷:由于现有夹具采用轴套类的定位方式,定位精度不高,容易出现偏心的情况;螺母压紧式结构需要采用扳手拧紧或松开螺母,费时费力,装夹效率低。为确保工件轴心线与机床分度轴和尾架顶尖轴心线一致。确保批量加工中每个工件加工精度达到5级(GB10095-2001),有必要设计一种高精度滚齿浮动夹具。
技术实现思路
:本技术的目的是针对现有技术的不足之处,提供一种高精度滚齿浮动夹具,确保工件轴心线与机床分度轴和尾架顶尖轴心线一致,同时采用高压清洁气体从夹具内部向外冲洗,确保心轴整个型腔清洁。本技术的技术解决措施如下:一种高精度滚齿浮动夹具,包括浮动夹头体、轴套、心轴和顶尖,所述轴套安装在浮动夹头体内左部,心轴安装在浮动夹头体内右部,且轴套卡接在心轴上;所述轴套左部中心装设有空心拉杆, ...
