Then, the push rods of the two grabbing cylinders 691 are retracted, so that the two clamping plates 693 are positioned on the upper outer side wall of the hub 100 and are clamped below the radial annular part formed on the upper outer side wall of the hub 100.

[0067] Then, the push rod of the main pushing oil cylinder 34 is retracted, the hub 100 is lifted, and the top surface of the grabbing lifting block 69 is pressed against the bottom surface of the lower fixing plate 68. At the same time, the top surface of the elastic protective layer 2 of the electromagnet block 1 is pressed against the top surface of the corresponding mounting concave hole. The process is that the push rod of the main pushing oil cylinder 34 is retracted for 2 seconds, and then the control host control middle electromagnet block 35 is closed, and the electromagnet block 1 is opened. At this time, the electromagnet block 1 adsorbs and fixes the grabbing lifting block 69;

[0068] Then, the moving block 65 is moved left or right through the operation of the servo motor 64, so that the sensing end of the corresponding second proximity switch 9 is close to the top end of the sensing column 7 and senses, indicating that it is moved to the position. At this time, the push rod of the corresponding lifting oil cylinder 51 pushes to lift the receiving plate 52, so that the middle part of the hub 100 is inserted into the center positioning column 53, and the outer part of the side supporting block 54 is lowered with the hub 100, thereby being retracted into the corresponding insertion slot 531. Until the bottom surface of the hub 100 is pressed against the top surface of the receiving plate 52. At this time, the outer end surface of all the side supporting blocks 54 abuts against the inner side wall of the middle part through hole of the hub 100, achieving placement.

[0069] Then, the push rod of the two grabbing oil cylinders 691 pushes, so that the two clamping plates 693 are away from each other, thereby achieving separation from the hub 100, and the placement is completed.

[0070] Then, the push rod of the lifting oil cylinder 51 is retracted, and when it is retracted, the receiving plate 52 is lowered, so that it is pressed against the top surface of the horizontal bending part 561 of the inner end, so that the return 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 part 561 of the outer end of the turnover rod 56, indicating that it is moved to the position. At this time, the moving block 65 is moved to the middle part through the operation of the servo motor 64, until the sensing column 7 is sensed by the sensing end of the first proximity switch 8, indicating that it is moved to the position.

[0071] At this time, it is indicated that the hub 100 has been placed and completed, and the robot can be used to grab the hub 100 and place it into the subsequent spinning equipment for spinning casting, which is very convenient.

[0072] The embodiment has two receiving frames 50, which can correspond to two robots, and can realize grabbing of the two robots, so that two spinning devices can be matched.

[0073] Finally, it should be noted that the above embodiments are only more representative examples of the present application. Obviously, the present application is not limited to the above embodiments, and there can be many variations. Any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments shall be considered as falling within the protection scope of the present application.
