一种汽车轮毂铸件同轴度检具
本专利技术涉及汽车零部件检测
,特别是一种汽车轮毂铸件同轴度检具。
技术介绍
汽车轮毂铸件的轴承孔同轴度是轮毂加工的一个重要指标,它与汽车的行驶系统有着密切的联系,所以轴承孔同轴度的检测显得尤为重要;目前,生产厂家对轮毂两轴承同轴位的同轴度检测一般采用三坐标系统来检测,其检测成本高、检测周期长且检测效率低,并且只能采取抽样检测的形式,不能在线检测,进而不能有效控制所有轮毂同轴度的合格率。
技术实现思路
本专利技术的目的在于克服现有技术的不足,提供一种汽车轮毂铸件同轴度检具。为实现上述目的,本专利技术采用了以下技术方案:一种汽车轮毂铸件同轴度检具,包括:底座,所述底座上固定有内涨器,所述内涨器呈圆盘状,内涨器的中心设有竖直通孔,内涨器的内部沿径向设有至少三个水平通孔,所述水平通孔与竖直通孔连通;任意所述的水平通孔内均安置有与水平通孔间隙配合的滑柱,所述滑柱的外端设有凹槽一,滑柱的内端为锥面,所述竖直通孔内安置有与竖直通孔间隙配合的滑球,所述滑球与各滑柱的锥面接触;所述内涨器的周圈设有与各所述的凹槽一在同一水平面上的凹槽二,各所述的凹槽一 ...
