[0002] In the stator resistance welding production process, four stations are often required to sequentially complete the processes of material feeding, hook welding, automatic feeding of round needles, pressing and fitting, and round needle welding. Each positioning fixture is evenly distributed and fixed on the table. After each station is completed, a lifting, clamping, and rotating robot or similar structure is needed to realize the product transfer. During product transfer, the robot must clamp the product, lift it, and then rotate it 90 degrees to complete the station transfer. This process is relatively time-consuming, slows down the production pace, and requires high precision, making the equipment prone to failure. Summary of the Invention

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] In the technical solution of this utility model, Figure 1 , Figure 2 , Figure 3 , Figure 4 This is a structural diagram illustrating the specific structure of an indexing system with a workstation rotation function according to this utility model. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model includes: an indexing plate 1, an indexing drive device 17, a rotating platform 3, a rotating drive device 4, and a positioning fixture 5.

[0021] The drive shaft of the indexing drive device 17 is fixed to the center of the indexing disk 1. Multiple rotating platforms 3 are arranged on the rotating platforms 3 and are equally spaced around the circumference of the indexing disk 1. Each rotating platform 3 is provided with a positioning fixture 5. The drive interface of each rotating platform 3 is connected to a rotating drive device 4. Each rotating drive device 4 is fixed to the lower surface of the indexing disk 1. Each rotating drive device 4 is connected to one end of the conductive slip ring 7 through a protection switch 14. The other end of the conductive slip ring 7 is connected to a power supply.

[0022] In one embodiment of this utility model, the utility model further includes multiple through-beam detection modules 15. These through-beam detection modules 15 are installed at various workstations and spaced apart from the indexing plate 1. The height of each through-beam detection module 15 corresponds to the height of the positioning fixture 5. Each through-beam detection module 15 is used to detect whether the positioning fixture 5 has a stator workpiece installed. Specifically, the through-beam detection device can employ through-beam detection sensors, which are mounted next to the indexing plate via brackets. One through-beam detection sensor is provided at each workstation, and the through-beam detection sensor detects whether the stator workpiece on the positioning fixture is properly installed.

[0023] In one embodiment of this utility model, the utility model further includes multiple positioning detection modules 12. The positioning detection modules 12 are installed at various workstations and spaced apart from the indexing plate 1. The height of each positioning detection module 12 corresponds to the height of the rotary drive device 4. Each positioning detection module is used to determine the distance between itself and the rotary drive device 4. Specifically, the positioning detection module 12 can be a proximity switch, which is mounted next to the indexing plate via a bracket. Each workstation has a corresponding proximity switch. When the rotary drive device reaches the proximity switch under the influence of the indexing plate, the proximity switch detects that the rotary drive device has reached its position.

[0024] In one embodiment of this utility model, the utility model further includes multiple pushing cylinders 2, which are installed at various workstations and spaced apart from the indexing plate 1. The height of the pushing cylinders 2 corresponds to the height of the positioning fixture 5, and the pushing cylinders 2 are used to open / close the positioning fixture 5. The positioning fixture 5 utilizes a mechanical spring for self-locking and reset, and is released by the cylinder pushing lever. The cylinders do not need to be fixed to the disc, thus solving the problem of cylinder air pipe layout. When the pushing cylinders 2 are extended, they open the positioning fixture to allow the stator workpiece to be placed into it. When the pushing cylinders 2 are retracted, the positioning fixture automatically closes to clamp the stator workpiece. It should be noted that the positioning fixture is a conventional technique in the art, and therefore will not be described in detail here.

[0025] In one embodiment of this utility model, the utility model further includes a controller, which is communicatively connected to the indexing drive device 17 and the rotary drive device 4, respectively. The controller is used to control the start and stop of the indexing drive device 17 and the rotary drive device 4. Specifically, the controller is connected to the position detection module 12 and the through-beam detection module 15, and controls the indexing drive device 17 and the rotary drive device 4 through the signals from the position detection module 12 and the through-beam detection module 15. The controller can be a PLC controller. The controller communicates with the rotary drive device 4 through the conductive slip ring 7, which effectively prevents the communication lines from becoming tangled.

[0026] In one embodiment of this utility model, the indexing drive device 17 includes a drive motor and a divider. The output shaft of the drive motor is connected to the drive shaft of the divider, and the connecting flange of the divider is connected to the indexing plate 1. The rotary drive device 4 is a servo motor, specifically a servo drive integrated machine.

[0027] The working principle of this utility model is as follows: The indexing plate 1 is fixed on the 5-division divider, which is fixed on the pad. When the push cylinder 2 extends, the positioning fixture is released, allowing the product to be placed on the positioning fixture. After the through-beam detection module 15 detects that the product is in place, the push structure 2 retracts, and the positioning fixture clamps the product. The servo drive motor starts, driving the positioning fixture 5 to rotate at the required angle. The 5-division divider drives the indexing plate to rotate. The indexing plate is made of aluminum alloy with a natural anodized finish and a machining accuracy of ±0.01mm. The divider positioning accuracy is ±0.01mm, ensuring the repeatability of the five positioning fixtures 5.

[0028] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
