一种用于球笼保持架加工的三爪夹具
本技术涉及夹具
,尤其涉及一种用于球笼保持架加工的三爪夹具。
技术介绍
球笼式等速万向节是汽车发动机上的重要传动部件之一,对于球笼保持架内、外球面尺寸,内、外球面中心偏置误差及形位公差精度要求非常高。由于球笼保持架壁较薄,加工中易变形,故其对夹具的要求也就非常高,如何设计出方便其安装,能快速实现精准定位,且保证夹紧后其受力均匀,是球笼保持架夹具的关键所在。
技术实现思路
针对现有技术中缺陷与不足的问题,本技术提出了一种用于球笼保持架加工的三爪夹具,通过向下拉伸支撑杆时,三爪板会受顶块挤压自动张开压紧工件,使球笼保持架受力均匀,且本技术对于球笼保持架的安装方便,定位快捷、精准。本技术解决其技术问题所采用的技术方案是:一种用于球笼保持架加工的三爪夹具,包括支撑杆、工件定位座、弹簧、顶块、爪板、爪板安装座和固定螺母,所述支撑杆套装在工件定位座内可上下滑动,弹簧、顶块和爪板安装座依次套装在支撑杆上,爪板安装座上方的支撑杆上安装有固定螺母,弹簧位于顶块和工件定位座之间,顶块与爪板安装座相连,爪板安装座内圆周均布有三片爪板,爪板通过销轴固定且可 ...
