Abstract

A multi-bearing loading platform applied to a cylindrical workpiece flaw detection machine comprises: a transfer module for driving a chassis to move between a loading and unloading station and a flaw detection station; the overturning platform is arranged on the bottom frame and connected with the bottom frame through an overturning mechanism, and the overturning mechanism is configured to control the overturning platform to be switched between the horizontal state and the inclined state; and the bearing driving module is arranged on the overturning platform and is used for supporting and positioning the to-be-detected workpiece and driving the to-be-detected workpiece to rotate around the axis of the to-be-detected workpiece. According to the multi-bearing loading platform applied to the cylindrical workpiece flaw detection machine, the overturning mechanism is arranged between the overturning platform and the bottom frame, so that the overturning platform can be switched between a horizontal state and an inclined state, and therefore, when a cylindrical workpiece is in an inclined state, residual magnetic suspension in a groove-shaped structure on the peripheral surface of the cylindrical workpiece can be poured out, and the magnetic suspension can be prevented from falling off. Therefore, the problem that the detection structure is affected due to the fact that the magnetic suspension covers the groove-shaped structure is avoided.
