[0033] A shaft support feeding assembly, which carries the components of the upper stage process to the processing surface;

[0034] An iron core shaft pressing assembly 5, which includes a pressing frame 501, a pressing base 502, an inner center support 503, a movable pressing plate 504, a top pressing shaft 506 and a pressing cylinder 505;

[0035] The pressing frame 501 is arranged on the machining surface, the pressing base 502 is arranged at the center of the bottom of the pressing frame 501, the inner center support 503 is arranged at the inner two sides of the pressing frame 501, the pressing cylinder 505 is arranged on the pressing frame 501 and the output end is connected with the movable pressing plate 504 through the top surface of the pressing frame 501, the top pressing shaft 506 is arranged on the movable pressing plate 504 and is correspondingly arranged on one side of the pressing base 502, and the movable pressing plate 504 is driven by the pressing cylinder 505 to ascend and descend on the inner center support 503.

[0036] In the embodiment, the core carrying assembly and the core detection assembly are the same device, which is a mechanical hand 1.

[0037] The double claws are arranged on the clamping jaw 2 of the mechanical hand 1, and the double claws are used for grabbing the core and the shaft support respectively.

[0038] The CCD camera detection 3 is used for detecting whether the core and the shaft support are good products.

[0039] The machining surface is provided with a reserved waiting position 4 for the good products detected by the CCD camera detection 3.

[0040] The core shaft support detection assembly further comprises a dynamic balance test piece 6 and a shaft jump test piece 7.

[0041] The balance test piece 6 and the shaft jump test piece 7 are arranged on the machining surface, the balance test piece 6 is used for testing the core and the shaft support assembly, and the shaft jump test piece 7 is directly used for detecting the shaft support.

[0042] Specifically,

[0043] Firstly, the double claws of the manipulator 1 grab the iron core and the shaft support from the previous device and place them on the left side of the extension position of the processing surface, and then the CCD camera detects 3. If the iron core and the shaft support are both good products processed by the previous device, the manipulator 1 continues to grab the iron core and the shaft support to perform the next process. Then, the manipulator 1 places the shaft support into the shaft jump test piece 7 to perform the shaft jump test, and determines whether the radial jump and the end face jump of the shaft support appear deformation errors. At the same time of the shaft jump test, the iron core is placed on the press-fit base 502. If the shaft support after the shaft jump test is a good product, the manipulator 1 grabs and places the shaft support on the press-fit base 502, that is, the iron core has been placed on the shell and is inserted into the shaft support for assembly. At this time, the output end of the press-fit cylinder 505 drives the movable pressing plate 504 to move downward on the inner center support 503. The top pressing shaft 506 on the movable pressing plate 504 is aligned with the shaft support and gradually presses the shaft support into the shell, thereby completing the press-fit process. The assembly after the press-fit of the iron core and the shaft support is a rotor. At this time, the manipulator 1 grabs the press-fit rotor and places it in the balance test piece 6 for dynamic balance test. The dynamic balance test is used to test whether the centrifugal force balance of the rotor is qualified when the rotor rotates at high speed. After the detection is completed, the workpiece is placed in the next process.
