Device for detecting oil hole continuity of rocker shaft of automobile engine

The invention provides a device for detecting the oil hole continuity of a rocker shaft of an automobile engine with the following structures. The device comprises a holder, a material tank arranged on the holder, a material rotating mechanism and a detection mechanism. The material rotating mechanism is used for feeding steel balls into a rocker shaft workpiece. The detection mechanism is used for detecting the speed of the steel balls sliding out of the rocker shaft workpiece. The steel balls in the material tank enter a feeding pipe under the action of gravity. When a driving motor drives amaterial rotating shaft to rotate to the opening end of a containing cavity and to align with the feeding inlet, the steel balls roll into the containing cavity, and the material rotating shaft continues to rotate; when the opening end of the containing cavity aligns with a material conveying inlet, the steel balls in the containing cavity enter the rocker shaft under the action of gravity, and rolls out from a detection
