At this time, the push rod of the main pushing cylinder 34 pushes, so that the elastic anti-skid layer fixed on the bottom surface of the middle electromagnet block 35 is pressed against the top surface of the main adsorption block 6, and the middle electromagnet block 35 is turned on (when the push rod of the main pushing cylinder 34 pushes for 2 seconds, the middle electromagnet block 35 is turned on. At this time, the elastic anti-skid layer fixed on the bottom surface of the middle electromagnet block 35 is pressed against the top surface of the main adsorption block 6), which is adsorbed and fixed. At this time, all the electromagnet blocks 1 stop turning on, and then Afterwards, as the push rod of the main pushing cylinder 34 continues to push, the grabbing lifting block 69 continues to descend (the bottom end of the middle electromagnet block 35 is the adsorption end, and the magnetism of its side wall is weaker, and the push rod of the main pushing cylinder 34 has a large thrust, so the middle electromagnet block 35 can descend normally), all the way to the bottom, at which time the two clamping plates 693 are located on the left and right sides of the lower wheel hub 100, and then, the push rods of the two grabbing cylinders 691 retract, and the two clamping plates 693 are close to the wheel and clamp the wheel hub 100, which is located below the radial annular portion formed on the upper outer wall of the wheel hub 100;

[0067] Then, the push rod of the main push cylinder 34 retracts, lifting the wheel hub 100 until the top surface of the grabbing lifting block 69 is pressed against the bottom surface of the lower fixed plate 68. At the same time, the elastic protective layer 2 fixed on the top surface of the electromagnet block 1 is pressed against the top surface of the corresponding mounting recess. This process is the push rod of the main push cylinder 34 retracting for 2 seconds. Then, the control host controls the middle electromagnet block 35 to close and the electromagnet block 1 to open. At this time, the electromagnet block 1 adsorbs and fixes the grabbing lifting block 69.

[0068] Then, the servo motor 64 is operated to make the moving block 65 move to the left or right, so that the sensing end of the corresponding second proximity switch 9 is close to and sensed by the top of the sensing column 7, indicating that it has moved into position. At this time, the push rod of the corresponding lifting cylinder 51 pushes to lift the receiving plate 52, so that the middle part of the wheel hub 100 is inserted into the center positioning column 53, and the outer part of the side support block 54 is retracted into the corresponding slot 531 as the wheel hub 100 descends, until the bottom surface of the wheel hub 100 is pressed against the top surface of the receiving plate 52. At this time, the outer end surfaces of all the side support blocks 54 are close to the inner side wall of the middle through hole of the wheel hub 100, so as to achieve placement;

[0069] Then, the push rods of the two grabbing cylinders 691 push the two clamping plates 693 away from each other, thereby achieving separation from the wheel hub 100 and completing the placement.

[0070] Then, the push rod of the lifting cylinder 51 retracts, and when it retracts, the receiving plate 52 descends, so that it presses against the top surface of the corresponding horizontal bending portion 561 at the inner end, so that the reset spring 57 is compressed. At this time, the sensing end of the proximity switch 58 corresponds to and senses the end surface of the horizontal bending portion 561 at the outer end of the corresponding flip rod 56, indicating that it has moved into place. At this time, the servo motor 64 is operated to make the moving block 65 move toward the middle until the sensing column 7 is sensed by the sensing end of the first proximity switch 8, indicating that it has moved into place.

[0071] At this point, it indicates that the wheel hub 100 has been placed, and the wheel hub 100 can be grabbed by a robot and placed in a subsequent spinning device for spin casting, which is very convenient.

[0072] This embodiment has two material receiving racks 50, which can correspond to two robots and realize the grasping of the two robots, thereby cooperating with two spinning equipments.

[0073] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
