[0032] Working process and principle:

[0033] When using the equipment in this scheme, the bearings 9 are loaded in batches through the loading channel 58, and then the hollow tube 10 is manually inserted into the hollow tube fixing fixture 4. The hollow tube 10 is fixed in the hollow tube fixing fixture 4 under the action of the magnetic suction member 22, and the iron core 8 is placed on the iron core positioning fixture 2. The equipment is started, and the bearing feeding sensor 18 detects whether there is a bearing 9 on the receiving platform 52. If not, the feeding vibration plate 51 is used for loading. After the bearing feeding sensor 18 detects the receiving platform, the bearing 9 is loaded. When there is a bearing 9 on the material table 52, the vibrating plate stops working. Then, the cutting cylinder 62 drives the receiving table 52 to move, and the receiving table 52 itself blocks the discharge port of the feeding vibrating plate 51.

Then, the core fixing cylinder 14 presses against the core 8, and the press 71 rises. At this time, the assembled core 8, hollow tube 10, and bearing 9 will remain in the core positioning tool 2. The core fixing cylinder 14 is reset to take out the assembled product. Of course, the step of the core fixing cylinder 14 pressing against the core 8 can also be performed when the core 8 is placed in the core positioning tool 2.
