[0072] like Figure 19-22 As shown, the rotating component 57 includes a rotating cylinder 2 571, a rotating cylinder mounting seat 572, a driving wheel 573, and a driven wheel 574. The rotating cylinder mounting seat 572 is arranged on the centering mounting plate 54, and a cavity for accommodating the driving wheel 573 is provided between the lower end thereof and the centering mounting plate 54. The rotating cylinder 2 571 is fixed above the rotating cylinder mounting seat 572, and a driving wheel 573 is provided on its output shaft. The driving wheel 573 and the driven wheel 574 are connected through an annular synchronous belt transmission, and the upper centering component 55 and the lower centering component 56 are connected to the driven wheel.

[0073] like Figure 19-22As shown, the upper centering component 55 includes an upper rotating sleeve 551, an upper positioning slider 552, and an upper inductive sensor 553. The upper inductive sensor 553 is inserted in the middle of the top of the upper rotating sleeve 551. The upper end of the upper rotating sleeve 551 is provided with a U-shaped groove centered on the upper inductive sensor 553. The upper positioning slider 552 is a U-shaped block, which is inserted in the U-shaped groove of the upper rotating sleeve 551 and is slidably connected to the sliding part in the middle of the U-shaped groove. The upper positioning slider 552 is inserted in the U-shaped groove in the same direction from the bottom of the upper rotating sleeve 551. Positioning parts one cooperating with the motor are provided on both sides of the top of the upper positioning slider 552. The positioning part one is a roller 554. A connecting block 555 is inserted at the lower end of the upper rotating sleeve 551, and the upper rotating sleeve 551 is fixedly connected to the connecting block 555 through an indexing pin. The connecting block 555 is connected to the driven wheel 574, so that when the driven wheel rotates, the upper rotating sleeve 551 and the upper positioning slider 552 rotate synchronously.

[0074] In the above structure, if Figure 21-22 As shown, a buffer spring 1 556 elastically connected to the sliding part is provided at the bottom of the upper inductive sensor 553, a buffer spring 2 557 is provided between the U-shaped interior of the upper positioning slider 552 and the bottom surface of the sliding part, and a buffer spring 3 558 is provided between the bottom of the upper positioning slider 552 and the connecting block 555. By providing the above-mentioned multiple buffer springs, when the upper positioning slider 552 and the upper inductive sensor 553 are connected to the motor, the impact can be reduced, the damage to the equipment can be reduced, and the working stability can be improved.

[0075] like Figure 18-22As shown, the lower centering component 56 includes a lower rotating sleeve 561, a lower positioning slide block 562, and a connecting shaft 563. A lower sensing sensor 564 elastically connected to the lower rotating sleeve 561 is provided in the middle of the bottom of the lower rotating sleeve 561. The lower positioning slide block 562 is also a U-shaped block, which is inserted in the U-shaped groove at the lower end of the lower rotating sleeve 561 and is slidably connected to the lower rotating sleeve 561. A connecting shaft 563 is inserted at the upper end of the lower rotating sleeve 561 and is fixedly connected to the connecting shaft 563 through a dividing pin. The upper end of the connecting shaft 563 is inserted in the bearing sleeve of the centering mounting plate 54 and is rotatably connected to the centering mounting plate 54. The top of the connecting shaft 563 is connected to the driven wheel 574. Similarly, when the driven wheel 574 rotates, the lower rotating sleeve 561 and the lower positioning slide block 562 rotate synchronously; positioning parts 2 cooperating with the transmission integrated component are provided on both sides of the bottom of the lower positioning slide block 562, and the positioning part 2 is a contoured plug rod 5621 integrally formed with the lower positioning slide block 562. In addition, a buffer spring 4 565 is provided between the top of the lower positioning slider 562 and the connecting shaft 563, which can also reduce the impact. In this embodiment, the positioning groove 1 on the motor is matched with the positioning part 1, and the positioning groove 2 on the transmission integrated component is matched with the positioning part 2. The positioning boss arranged at intervals with the positioning groove 2 and the positioning groove 1 form a matching positioning connection structure. When centering, the centering mechanism 5 moves to the top of the tooling 1 8 of the press-fitting station, the lower centering component 56 descends close to the transmission integrated component, and the clamping claw 3 652 on the press-fitting mechanism 6 clamps the motor and descends close to the upper centering component 55. The rotating component 57 drives the upper centering component 55 and the lower centering component 56 to rotate synchronously until the positioning part 1 and the positioning part 2 match the corresponding positioning grooves, the positioning part 1 and the positioning part 2 are inserted into the corresponding positioning grooves, the upper inductive sensor 553 and the lower inductive sensor 564 are triggered, and the rotating component 57 stops, thereby realizing the centering of the motor and the transmission integrated component. It should be noted that when the upper centering component 55 is connected to the motor, the motor will rotate with the upper centering component 55 until it is aligned with the transmission integrated component; similarly, when the lower centering component 56 is connected to the transmission integrated component, the transmission component in the transmission integrated component will rotate with the lower centering component 56 until it is aligned with the motor. In summary, it can be seen that the motor and the transmission integrated component can be accurately aligned, which provides convenience for the subsequent press assembly.

[0076] like Figure 23-25As shown, the pressing mechanism 6 includes a servo press 61, a pressing plate 62, a pressure plate 63, and a guide rod 64. The pressing plate 62 is fixed on the frame 9, and the servo press 61 is fixed on the pressing plate 62. A pressure plate 63 is provided at its output end. Two guide rods 64 symmetrically arranged on both sides of the servo press 61 are also inserted on the pressing plate 62. The lower end of the guide rod 64 is connected to the pressure plate 63. A clamping assembly 65 for clamping the motor is provided below the pressure plate 63. The clamping assembly 65 includes a clamping cylinder 3 651, and the output end of the clamping cylinder 3 651 is provided with two clamping jaws 3 652 arranged opposite to each other.

The clamping portion extends along the axial direction of the motor, and includes an upper clamping portion 6522, a lower clamping portion 6523, and a groove located between the upper clamping portion 6522 and the lower clamping portion 6523. The clamping direction of the clamping jaw 3 652 is perpendicular to that of the clamping jaw 2 45, so as to ensure that the clamping jaw 3 652 and the clamping jaw 2 45 can clamp at the same time without affecting each other. When the transplanting mechanism 4 moves to the press-fitting station, the clamping jaw 3 652 and the clamping jaw 2 45 are exchanged, and the motor is transferred from the clamping jaw 2 45 to the clamping jaw 3 652.

[0077] like Figure 24-25 As shown, the clamping assembly 65 also includes a limit cylinder 653 and a limit block 654. The limit cylinder 653 is installed on the cylinder body of the clamping jaw cylinder 3 651, and its output end is provided with a limit rod 655. The limit rod 655 is inserted in the slide 656 and is slidably connected with the slide 656. The limit block 654 is arranged on one side of the upper end of the connecting portion 6521 of the clamping jaw 3 652. When pressing, the limit rod 655 extends out of the slide 656 through the limit cylinder 653 to block the limit block 654, limiting the opening stroke of the clamping jaw cylinder 3 651, so that the clamping jaw 3 652 can clamp the motor with a gap during pressing, and the clamping gap of the clamping jaw 3 is not greater than 2mm. When the positioning portion 1 of the upper positioning slide block 552 is inserted into the positioning groove of the motor, the motor will rotate from the driven wheel 574 at any time, and this gap can leave space for the motor to rotate, which can avoid damage to the equipment and products.

[0078] like Figure 24-25As shown, the clamping jaw 3 652 is also provided with a magnetic suction component, which includes a needle-type cylinder 657 and an electromagnet 658. The lower end of the clamping part is provided with an opening, which divides the lower clamping part 6523 into two. The side wing boss of the mounting screw is located between the openings. The needle-type cylinder 657 is arranged at the top of the opening, and an electromagnet 658 is arranged at its output end. The electromagnet 658 is movably connected with the screw inserted in the side wing boss, and a detection sensor is arranged on the outer side of the lower clamping part 6523 to detect whether the screw is adsorbed, and to detect the position of the screw. During press-fitting or centering, the needle-type cylinder 657 drives the electromagnet 658 to descend to adsorb the screw in the mounting hole, and then rises to separate the screw from the motor, so as to avoid the collision of the lower end of the screw with the transmission integrated component or equipment during press-fitting, or even knocking the screw off, thereby improving the safety of operation. After the press-fitting is completed, the screw is placed in the mounting hole of the motor.
