筒类零件外圆磨削加工夹具
:本技术涉及液压油缸筒类零件在外圆加工,尤其是外圆磨削加工时工件的装夹定位夹具。
技术介绍
:液压油缸筒类零件(尤其是多级缸杆筒类零件)在外圆磨削加工过程中,要求要以内孔作为外圆加工的基准,其内孔和外圆的同轴度要求极高,而现有的装夹方式不能做到此要求,造成内孔与外圆不同心,影响产品性能。在常见的此类零件外圆加工过程中,所使用的是双顶尖支撑装夹的方式,缺点是:筒在经过内孔加工后,虽然采用双顶尖在筒口部对顶支撑,但是不能做到完全以内孔为加工基准,而且会受到端面垂直度和加工毛边的影响,如果端面垂直度不能保证或有毛边,就会造成装夹的零件不水平(内孔和外圆不同心)。
技术实现思路
:本技术目的在于克服上述缺点,提供筒类零件外圆磨削加工夹具,其完全以内孔作为装夹定位的夹具,保证加工时内孔和外圆的同轴度在要求范围内。为达成上述目的,本技术采用如下技术方案:筒类零件外圆磨削加工夹具,包括由内向外依次设置的涨芯,涨环体,弹性件,涨环支撑块,轴向固定件,顶尖组件;其中,涨芯带有一外斜面,与涨环体的内斜面配合,涨环体与涨环支撑块通过紧钉螺钉连接,涨环体与涨环支撑块之间设有弹性件,涨环支撑块与工件内孔接触,轴向固定件将涨芯及涨环体固定,顶尖组件与涨芯配合并带动所述涨芯,涨环体,弹性件,涨环支撑块,轴向固定件及待加工工件一体转动。进一步,轴向固定件包括垫块及螺钉,垫块和螺钉将涨芯、涨环体固定。进一步,所述的顶尖组件包括顶尖及拨杆,顶尖顶抵在涨芯中心,通过拨杆带动所述涨芯,涨环体,弹性件,涨环支撑块,轴向固定件及待加工工件一体转动。进一步,所述的弹性件为设置在涨 ...
