1) placing the bottom plate of the motor workpiece downwards onto the pushing platform 22 through a robot or a manipulator, and controlling the lifter 232 to lift to align the center of the motor workpiece with the center height of the chuck body 121; 2) the transverse pushing mechanism 24 drives the movable bottom plate 233 to move horizontally in the direction close to the clamping mechanism 12, so as to push the motor workpiece into the clamping jaw of the clamping mechanism 12; 3) when the position sensor detects that the motor workpiece is pushed to the right position, the longitudinal pushing mechanism 15 drives the clamping driving motor 141 to move downwards, the locking gear ring 123 is driven to rotate reversely by the meshing of the second transmission gear 142 and the locking gear ring 123, so that the clamping jaws 122 of the clamping mechanism 12 are outwards opened, expanded and clamped in the inner hole of the motor workpiece, the motor workpiece is clamped, and after the motor workpiece is clamped, the longitudinal pushing mechanism 15 drives the clamping driving motor 141 to move upwards, so that the second transmission gear 142 is separated from the locking gear ring 123; 4) then the rotary driving mechanism 13 controls the clamping mechanism 12 to drive the motor workpiece to rotate 180 degrees, so that the bottom plate of the motor workpiece is placed upwards; 5) then the longitudinal pushing mechanism 15 drives the clamping driving motor 141 to move downwards again, so that the second transmission gear 142 is meshed with the locking gear ring 123, then the magnet lifting appliance is adopted to suck the bottom plate of the workpiece, at the moment, the locking gear ring 123 is driven to rotate positively, so that the clamping mechanism 12 releases the motor workpiece; 6) hoisting the motor workpiece to a leveling machine to level a base plate of the motor workpiece; 7) the positioner 100 and the workpiece pusher 200 are reset to start the next operation cycle.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
