Spiral spline gauge for isolator assembly

The utility model relates to the field of mechanical manufacturing, and discloses a spiral spline gauge for an isolator assembly, which comprises a gauge body, the gauge body comprises a spline shaft at the front end and an operating handle, and a first external spline and a second external spline are arranged on the spline shaft at intervals. The utility model has the following advantages and effects: the gauge body is provided with the two spiral external splines which are arranged at intervals and are in one-to-one correspondence, so that the shape and the depth of the internal spline in the isolator assembly can be judged, the manufacturing result can be detected, and the detection accuracy can be improved. And each isolator assembly can be ensured to be used normally, and products which are unqualified after leaving a factory are avoided. 本实用新型涉及机械制造领域，公开了一种用于单向器总成的螺旋花键量规，包括量规本体，所述量规本体包括前端的花键轴和操作把手，所述花键轴上间隔设置有第一外花键和第二外花键，所述第一外花键和第二外花键上的花键为螺旋形且相互一一对应，本实用新型具有以下优点和效果：通过在量规本体上设置两个相间隔且一一对应的螺旋外花键，能够判断单向器总成中内花键
