[0026] The lifting driver in the detection structure 3 drives the support plate to descend, and at the same time drives the first diameter detection driver and the second diameter detection driver to descend, and the two first detection gauges and the two second detection gauges are respectively inserted into the two commutators, and the first diameter detection driver drives the two first detection gauges to open, and the two first detection gauges detect the inner hole of the commutator in the first diameter detection station in the X direction; the second diameter detection driver drives the two second detection gauges to open, and the two second detection gauges detect the inner hole of the commutator in the second diameter detection station in the Y direction; the lifting driver drives the support plate to rise, and at the same time drives the first diameter detection driver and the second The diameter detection driver rises, and the two first detection gauges and the two second detection gauges are separated from the two commutators respectively; the longitudinal driver drives the conveying plate to approach the commutator, so that the commutator is in the conveying hole of the conveying plate, and the transverse driver drives the carrier plate 8 to move transversely, so that the conveying plate on the carrier plate 8 moves transversely, and the commutator originally in the first diameter detection station is moved to the second diameter detection station, and the commutator originally in the second diameter detection station is moved to the rejection station; when a defective product is detected, the rejection driver extends the push block 5 by driving the push rod 4, and the defective commutator pushed out by the push block 5 falls from the blanking port into the blanking slide 9;
[0027] A collecting box 10 is arranged on the top of the mounting plate 1, and two limit blocks 11 are arranged on the top of the mounting plate 1, one end of the two limit blocks 11 is connected to a mounting seat 12, a bidirectional screw rod 13 is inserted through one end of the mounting seat 12, and the outer wall of the bidirectional screw rod 13 is threadedly connected to two threaded connecting blocks 14, the tops of the two threaded connecting blocks 14 are connected to L-shaped limit blocks 15, a guide rod 16 is arranged inside the mounting seat 12, and a fixing block 17 is fixedly connected to the outer wall of the collecting box 10, and a slot 18 is opened at the end of the fixing block 17.
[0028] Preferably: the two limit blocks 11 are symmetrically distributed on both sides of the collection box 10, one end of the bidirectional screw rod 13 forms a rotating connection structure with the mounting seat 12 through a bearing, an opening is provided at the top of the mounting seat 12, and one end of the L-shaped limit block 15 extends to the outside through the top opening of the mounting seat 12, and one end of the two threaded connection blocks 14 is sleeved on the outer wall of the guide rod 16.
[0029] When in use, the collection box 10 is placed between the two limit blocks 11 so that the fixed block 17 can be located directly above the mounting seat 12. At this time, the two threaded connection blocks 14 on the outer wall of the collection box 10 can be rotated to drive the L-shaped limit block 15 on the top to move toward each other. As the two L-shaped limit blocks 15 gradually approach each other, one end of the L-shaped limit block 15 will be inserted into the slot 18 at the end of the fixed block 17. At this point, the collection box 10 is fixedly installed below the blanking slide 9 for blanking collection.

[0033] Working principle: When using the commutator inner hole diameter detection mechanism for collecting defective products, the collection box 10 is placed between the two limit blocks 11 so that the fixed block 17 can be located directly above the mounting seat 12. At this time, by rotating the two-way screw 13, the two threaded connection blocks 14 on the outer wall can drive the L-shaped limit block 15 on the top to move toward each other. As the two L-shaped limit blocks 15 gradually approach each other, one end of the L-shaped limit block 15 will be inserted into the slot 1 at the end of the fixed block 17. 8, the collection box 10 is fixedly installed under the blanking chute 9. After that, the rejection driver extends the push block 5 by driving the push rod 4, and the defective commutator pushed out by the push block 5 falls from the blanking port into the blanking chute 9 and falls into the collection box 10 for collection. Through the setting of the buffer plate 19 and the spring 20, when the falling commutator contacts the buffer plate 19, the elastic structure between the buffer plate 19 and the inner wall of the collection box 10 is used to buffer it, thereby reducing the falling gravity to avoid its damage.
