[0002] The rotor usually includes a rotor shaft and an iron core. During the rotor assembly process, the rotor shaft needs to be assembled to the iron core, which generally includes the following steps: supplying the rotor shaft and assembling the iron core on the rotor shaft.

The outer sides of the guide blocks 28 are provided with adjustment blocks 58 that match the adjustment grooves 49. The adjustment blocks 58 can be slidably clamped in the adjustment grooves 49, so that the guide blocks 28 can be adjusted on the positioning plates 27. Height. After the height adjustment is completed, the adjustment block 58 is screwed on the positioning plate 27, so that the guide block 28 is fixedly installed on the inner side of the positioning plate 27. A guide groove 50 is provided on the inner side surface of the guide block 28, so that the guide grooves 50 of the two guide blocks 28 form a guide hole 57 that matches the rotor shaft when the guide grooves 50 are in the closed state. The guide hole 57 is coaxially arranged with the discharge port 6, and the rotor shaft is axially guided through the guide hole 57. The positioning plates 27 on both sides are provided with shaft sensors 53 for detecting whether the rotor shaft is in place.

[0066] Furthermore, integrally formed positioning blocks 51 are provided on both sides of the feeding rail 3 , and a track for conveying the iron core is formed between the positioning blocks 51 on both sides, and a rotor sensor for detecting whether the iron core is in place is provided on the feeding rail 3 , and the rotor sensor is fixedly installed on the outer side of the positioning block 51 .

[0067] During assembly, first, when the iron core on the feeding rail 3 is sent to the shaft input station and the rotor sensor detects that there is an iron core in the material track, the shaft pushing cylinder 8 is started, and the shaft pushing plate 9 is pushed out through the transmission shaft 35, so that the rotor shaft falling into the discharge trough 10 is pushed out from the discharge port 6 of the material frame 5 to the bottom of the top shaft device 11. At this time, the discharge trough 10 is located above the feed port 23 of the feeding channel 22. Then, the split shaft cylinder 12 on the top shaft device 11 is started, and the split shaft cylinder 12 presses the rotor shaft located in the discharge trough 10 through its split shaft 55 to push the rotor shaft out of the discharge trough 10, so that the rotor shaft falls to In the feed port 23 located below it, the rotor shaft enters the feeding channel 22 of the feeding device 15 from the feed port 23, and then the split-shaft cylinder 12 retracts. When the split-shaft cylinder 12 is reset, the push-shaft cylinder 8 pulls the push-shaft plate 9 back in the opposite direction, so that the discharge trough 10 on the push-shaft plate 9 moves again to the discharge port 6 of the material frame 5 to load the rotor shaft, thereby realizing automatic feeding. At the same time, the driving cylinder 25 is started, and the transmission block 37 drives the connecting plate 44 to make the first clamping block 42 and the second clamping block 43 close to each other in a closed state, so that the positioning plates 27 on both sides of the bottom of the shaft clamp 26 position and close the iron core in the track.

[0068] Next, after the rotor shaft falls from the feed port 23 into the feed channel 22, the rotor shaft is guided by the arc-shaped guide slide portion 21 on the slide plate 20, so that the rotor shaft slides obliquely toward the discharge port 6, and the assembly end of the rotor shaft first enters the vertical discharge track 41 at the discharge port 6. When the rotor shaft continues to slide down to the discharge port 6, the rotor shaft will automatically correct from the inclined state to the vertical state under the action of the vertical discharge track 41, waiting for the next step.

[0069] Then, the rotor shaft passes through the shaft sleeve 45 at the discharge port 6 under the action of gravity and falls into the clamping hole 48 in the center of the shaft clamp 26. Then, the pressing cylinder 13 on the top shaft device 11 is started, and the pressing shaft 56 of the pressing cylinder 13 extends into the feeding channel 22, and coaxially presses the rotor shaft toward the iron core, so that the rotor shaft passes through the clamping hole 48 of the shaft clamp 26 and the guide hole 57 in the guide block 28 in turn and is inserted into the middle hole of the iron core. After the shaft base is inserted, the pressing cylinder 13 retreats.

[0070] Finally, when the pressing cylinder 13 returns to its original position, the first clamping block 42 and the second clamping block 43 are opened under the drive of the driving cylinder 25, so that the positioning plates 27 on both sides of the bottom of the shaft clamp 26 open the iron core in the track, and the iron core after the shaft insertion is completed is sent to the next workstation through the feeding rail 3. Then, when the iron core is sent to the shaft entry station again and detected by the rotor sensor, the shaft clamp 26 is closed again, and the above steps are repeated to realize the automatic directional shaft insertion assembly process.

[0071] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Technical personnel in this industry can make some deformation and modifications under the inspiration of this technical solution. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
