在对星齿轮进行检测时，一般会采用触控笔和夹具进行配合，对齿轮的径向跳动、公法线长度变动、公法线长度平均偏差、齿厚误差等参数进行测量，例如申请号为DE102007015947A1且专利名称为用于测量空间物体的合适方法和装置，能够对夹具上的物体进行轮廓的测量。
但是该装置在对结构较小的星齿轮进行检测时，星齿轮的一端上会安装定位模具为星齿轮提供标准尺寸；由于星齿轮的内壁处设置有供轴和滚珠等结构进行安装的安装槽，若需要对安装槽进行检测，则需要拆卸已经夹持定位以后星齿轮上的定位模具，一般采用人工的方式将定位模具取出，若定位模具的取出与星齿轮之间出现碰撞，可能会影响星齿轮到装夹精度，会影响星齿轮的检测精度；同时，采用人工方式对定位模具取出时，取出效率较低，还会影响对星齿轮的检测效率。

步骤1：准备星齿轮成品直线度检测设备和若干待测星齿轮，控制调平单元对定位夹具进行调平，定位夹具的上端面与水平面平行；
步骤2：将限位垫安装到待测星齿轮的一端上，凸台的侧壁与待测星齿轮的内壁相抵；然后将限位垫和待测星齿轮放置到定位夹具上，定位夹具夹紧限位垫；控制主动齿轮正向转动，主动齿轮与盘状齿啮合且带动固定杆下移，定位模具、固定轴和延伸管同步下移，定位模具、固定轴和延伸管探入到星齿轮内对星齿轮进行限位，且激光发射器发出的激光被激光接收器准确接收，待测星齿轮定位完成；
步骤3：通过信息显示输入终端处控制探针下移，探针对定位模具的外壁进行定位，对待测星齿轮的准确尺寸进行测定；然后探针继续下移，对待测星齿轮齿顶、齿根、分度圆和径向跳动进行测量；
步骤4：主动齿轮反向转动，主动齿轮与盘状齿啮合且带动固定杆上移，定位模具、 固定轴和延伸管同步上移，定位模具、固定轴和延伸管与待测星齿轮脱离，探针移动至待测星齿轮的内壁处，对待测星齿轮内壁上的安装槽的竖直度进行测量；
步骤5：测量完成后，拆卸下完成测量的待测星齿轮，待测星齿轮与定位模具、固定轴和延伸管脱离即可。
通过上述设置，步骤1能够对定位夹具进行调平，为后续待测星齿轮的精准安装提供条件；步骤2中，定位模具、固定轴和延伸管在主动齿轮和固定杆的控制下下移，且激光接收器的信号能够被实时监测，便于控制定位模具、固定轴和延伸管与定位夹具之间的配合稳定，待测星齿轮定位完成；步骤3和步骤4，能够依次完成对待测星齿轮的外壁参数和内壁安装槽处的参数进行快速且精准的检测；同时也便于根据待测星齿轮的尺寸调节，定位模具、固定轴和延伸管的整体长度，便于对不同规格的待测星齿轮进行检测，提高对待测星齿轮检测的适应性；同时在主动齿轮、盘形齿和固定杆的配合下，定位模具、固定轴和延伸管的上下移动不会出现晃动，能够让定位模具、固定轴和延伸管与待测星齿轮稳定分离，避免对待测星齿轮移动后对内壁的安装槽检测产生影响。

当在采用星齿轮成品直线度检测设备对待测星齿轮80进行时，采用以下检测方法，具体包括以下步骤：
步骤1：准备星齿轮成品直线度检测设备和若干待测星齿轮80，根据信息显示输入终端70显示的定位夹具20水平度进行查看，根据调平单元201的实时反馈，处理器将相应平整度信息传递至信息显示输入终端70处，此时控制调平单元201对定位夹具20进行调平，使得定位夹具20的上端面与水平面平行；
步骤2：将限位垫301安装到待测星齿轮80的一端上，凸台302的侧壁与待测星齿轮80的内壁相抵，让待测星齿轮80的端面保持平整状态；然后将限位垫301和待测星齿轮80放置到定位夹具20上，定位夹具20夹紧限位垫301，使得待测星齿轮80保持平整的 夹持状态；然后电动机601带动主动齿轮602正向转动，主动齿轮602与盘状齿603啮合且带动固定杆501下移，定位模具401、固定轴402和延伸管405同步下移，定位模具401、固定轴402和延伸管405探入到星齿轮80内对星齿轮80进行限位，凸缘403与待测星齿轮80的安装槽801处相抵，且激光发射器702发出的激光被激光接收器703准确接收，激光接收器703的接收信号被处理器传递至信息显示输入终端70上，可得知定位模具401、固定轴402和延伸管405的定位准确，让待测星齿轮80定位完成；在此过程中，可控制固定轴402和延伸管405上第一螺纹406和第二螺纹407的啮合长度，进而控制延伸管405位于环状槽404外的长度，便于定位模具401、固定轴402和延伸管405对不同长度规格的待测星齿轮80进行限位；
