[0038] The working principle of this utility model is as follows: During use, the upper and lower bearing hoppers are fed. The upper servo motor drives the upper push plate to move, and the upper open placement slot moves to below the upper bearing hopper. The upper bearing in the upper bearing hopper falls naturally into the placement slot by gravity. The lower servo motor drives the lower push plate to move, and the lower open placement slot moves to the feeding port of the lower bearing hopper. Then, the lower bearing feeding cylinder drives the feeding push block to push the lower bearing into the lower open placement slot. Then, driven by the two servo motors, the two push plates carry the two bearings through the bearing through holes to the designated position. Finally, the upper servo cylinder drives the upper push rod to move downward. Insert the upper bearing, then move the upper bearing upwards to adsorb onto the upper bearing adsorption sleeve. The lower servo cylinder drives the lower push rod upwards to insert the lower bearing, then moves the lower bearing downwards to adsorb onto the lower bearing positioning core. After both bearings are adsorbed, the two push plates move back to their original positions. Then, place the flywheel to be processed on the positioning flange. Then, drive the upper and lower push rods with the upper and lower servo cylinders respectively, moving the flywheel up and down to press the two bearings into the designated positions on the flywheel. During this process, the degree of pressing can be reflected by the stroke of the servo cylinder and the feedback value of the pressure sensor. After pressing is completed, the push rod retracts, and then the flywheel is removed.
