[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-5 As shown, an assembly centering device includes a centering mounting plate 1, an upper centering component 2 disposed above the centering mounting plate 1, and a lower centering component 3 disposed below the centering mounting plate 1. The upper centering component 2 is used to detect the position of the positioning motor, and the lower centering component 3 is used to detect the positioning transmission integrated component. The centering mounting plate 1 is also provided with a rotating component 4 that drives the upper centering component 2 and the lower centering component 3 to rotate synchronously.

[0028] In the above structure, such as Figure 2-5 As shown, the rotating assembly 4 includes a rotating cylinder 41, a rotating cylinder mounting base 42, a driving wheel 43, and a driven wheel 44. The rotating cylinder mounting base 42 is disposed on the centering mounting plate 1, and a cavity for accommodating the driving wheel 43 is provided between its lower end and the middle mounting plate 1. The rotating cylinder 41 is fixed above the rotating cylinder mounting base 42, and the driving wheel 43 is disposed on its output shaft. The driving wheel 43 and the driven wheel 44 are connected by a ring synchronous belt drive. The upper centering assembly 2 and the lower centering assembly 3 are connected to the driven wheel 44.

[0029] Among them, such as Figure 2-5 As shown, the upper centering component 2 includes an upper rotating sleeve 21, an upper positioning slider 22, and an upper sensing sensor 23. The upper sensing sensor 23 is inserted into the middle of the top of the upper rotating sleeve 21. The upper end of the upper rotating sleeve 21 has a U-shaped groove centered on the upper sensing sensor 23. The upper positioning slider 22 is a U-shaped block, inserted into the U-shaped groove of the upper rotating sleeve 21 and slidably connected to the sliding part in the middle of the U-shaped groove. The upper positioning slider 22 is inserted into the U-shaped groove from the bottom of the upper rotating sleeve 21 in the same direction. The top two sides of the upper positioning slider 22 have a positioning part that cooperates with the motor. The positioning part is a roller 24. The lower end of the upper rotating sleeve 21 has a connecting block 25 inserted, and the upper rotating sleeve 21 is fixedly connected to the connecting block 25 through an indexing pin. The connecting block 25 is connected to the driven wheel 44, so that when the driven wheel 44 rotates, the upper rotating sleeve 21 and the upper positioning slider 22 rotate synchronously.

[0030] In the above structure, such as Figure 4-5 As shown, the bottom of the upper sensing sensor 23 is provided with a buffer spring 26 that is elastically connected to the sliding part; the U-shaped interior of the upper positioning slider 22 is provided with a buffer spring 27 between it and the bottom surface of the sliding part; and the bottom of the upper positioning slider 22 is provided with a buffer spring 28 between it and the connecting block 25. By setting up these multiple buffer springs, the impact can be reduced when the upper positioning slider 22 and the upper sensing sensor 23 are connected to the motor, thus reducing damage to the equipment and improving operational stability.

[0031] Among them, such as Figure 2-5As shown, the lower centering assembly 3 includes a lower rotating sleeve 31, a lower positioning slider 32, and a connecting shaft 33. The lower rotating sleeve 31 has a lower sensing sensor 34 elastically connected to it at the bottom center. The lower positioning slider 32 is also a U-shaped block, inserted into the U-shaped groove at the lower end of the lower rotating sleeve 31 and slidably connected to the lower rotating sleeve 31. The connecting shaft 33 is inserted into the upper end of the lower rotating sleeve 31 and fixedly connected to the connecting shaft 33 by an indexing pin. The upper end of the connecting shaft 33 is inserted into the bearing sleeve of the centering mounting plate 54 and rotatably connected to the centering mounting plate 54. The top of the connecting shaft 54 ​​is connected to the driven wheel 574. Similarly, when the driven wheel 574 rotates, the lower rotating sleeve 31 and the lower positioning slider 32 rotate synchronously. The lower positioning slider 32 has a second positioning part on both sides at the bottom that cooperates with the transmission integrated component. The second positioning part is a contoured insert 321 integrally formed with the lower positioning slider 32. In this embodiment, the positioning part one is the positioning groove one on the motor, and the positioning part two is the positioning groove two on the transmission integrated component. The positioning bosses that are spaced apart from the positioning groove two form a positioning connection structure that cooperates with the positioning groove one.

[0032] In addition, such as Figure 4-5 As shown, a buffer spring 35 is provided between the top of the lower positioning slider 32 and the connecting shaft 33, which can also reduce impact.

[0033] During alignment, the alignment mechanism 5 moves above the tooling 8 at the pressing station, and the lower alignment component 3 descends closer to the transmission integrated component. Simultaneously, the clamping component (not shown in the figure) moves to clamp the motor closer to the upper alignment component 2. The rotating component 4 drives the upper alignment component 2 and the lower alignment component 3 to rotate synchronously until the positioning part 1 and the positioning part 2 match the corresponding positioning slots. The positioning part 1 and the positioning part 2 are then inserted into the corresponding positioning slots. The rotation component 4 stops when both the upper sensing sensor 2 and the lower sensing sensor 3 are triggered, thus achieving alignment between the motor and the transmission integrated component. It should be noted that when the upper alignment component 2 is docked with the motor, the motor will rotate with the upper alignment component 2 until it is aligned with the transmission integrated component; similarly, when the lower alignment component 3 is docked with the transmission integrated component, the transmission component inside the transmission integrated component will rotate with the lower alignment component 3 until it is aligned with the motor. In summary, this utility model can automatically align the components, is simple and convenient to operate, and can ensure accurate alignment between the motor and the transmission integrated components, thus facilitating the subsequent assembly of the motor. It not only improves production efficiency but also avoids collision damage to the product.

[0034] Example 2

[0035] Based on the structure of Example 1, such as Figure 1As shown, to ensure the flexibility of the alignment device, the above-mentioned assembly alignment device also includes a linear module 5, an alignment moving seat 6, and a moving cylinder 7. The output end of the linear module 5 is equipped with the alignment moving seat 6, which can drive the alignment moving seat 6 to move along the X direction. The moving cylinder 7 is mounted on the alignment moving seat 6, and its output end is equipped with an alignment mounting plate 1, which can drive the alignment mounting plate 1 to move along the Y direction, i.e., the vertical direction. The alignment moving seat 6 is also equipped with a slide rail that is slidably connected to the alignment mounting plate 1. By driving the alignment mounting plate to move in the X and Y directions, it is easy to connect the upper and lower alignment components with the motor and transmission integration components.
