Description

Technical Field

[0001] This utility model relates to the field of motor stator lamination stamping technology, specifically to a high-efficiency precision motor stator lamination stamping forming machine. Background Technology

[0002] Motor stator laminations are an important component of motor stators. They typically refer to the fan-shaped or other shaped metal sheets made of silicon steel that form the core of the motor stator. They have characteristics such as high magnetic permeability and low loss, making them an ideal material for manufacturing motor stator cores.

[0003] According to Chinese Patent Publication No. CN218693279U, "A Stamping Die for Producing Motor Stator Laminations," the main feature is a die consisting of a fixed base, a lower die, a clamping plate, a threaded rod, and a top plate. Rotating the threaded rod moves the clamping plate, facilitating the fixing of laminations of different sizes and minimizing movement during processing, thus improving the precision of the laminations. Furthermore, by incorporating limit blocks, limit grooves, and limit rods, the threaded rod is limited by inserting the limit rod into the limit blocks and limit grooves, further preventing movement during operation and enhancing the stability of the lamination processing.

[0004] To increase the stamping speed of motor stator laminations, batch stamping equipment is usually set up. However, after the motor stator laminations are stamped, they need to be manually removed. To reduce the risk of manual intervention, protective structures are set up to reduce the risk, which in turn reduces the efficiency of batch stamping.

[0005] Therefore, a high-efficiency and precision motor stator lamination stamping machine is proposed to solve the problem that manual handling of the stamped motor stator laminations is required during the batch stamping process, and that the use of a protective structure increases the stamping and handling time, thereby reducing the efficiency of batch stamping. Utility Model Content

[0006] The technical problem to be solved by this utility model is that manual handling of the stamped motor stator laminations is required during the batch stamping process, and the use of protective structures increases the stamping and handling time, reducing the efficiency of batch stamping. Therefore, a high-efficiency and precision motor stator lamination stamping forming machine is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: a high-efficiency precision motor stator lamination stamping and forming machine, including a fixed plate, a first motor, a first transmission mechanism, a fixed mold, a connecting plate, a first screw, and a moving mold. An extension plate is fixedly connected to one side of the fixed plate, a second motor is fixedly connected to one side of the extension plate, a second transmission mechanism is rotatably connected to the extension plate, a sliding groove is opened on the upper side of the extension plate, a third motor is fixedly connected to one side of the extension plate located in the sliding groove, a second screw is fixedly connected to the output end of the third motor, a moving plate is threadedly connected to the second screw, a third motor is fixedly connected to the moving plate, a rotating rod is fixedly connected to the output end of the third motor, a rotating plate is fixedly connected to the rotating rod, an air pump is fixedly connected to one side of the rotating plate, a contact plate is fixedly connected to the bottom side of the air pump on the rotating plate, a cavity is opened in the contact plate, a buffer pad is fixedly connected to the bottom end of the contact plate, and through holes are evenly opened on the bottom sides of the contact plate and the buffer pad, and the cavity communicates with the through holes.

By rotating the adjusting rod, the pressure roller can squeeze the motor stator laminations, thereby improving the flatness of the motor stator laminations.

[0009] As a preferred technical solution of this utility model, a distance sensor is uniformly fixedly connected to one side of the bottom end of the support plate. The distance sensor corresponds to the second transmission mechanism. By setting the distance sensor to monitor the distance between the motor stator lamination and the distance sensor, the position where the distance sensor protrudes too much can be detected, thereby improving the quality of the stamped motor stator lamination.

[0010] As a preferred technical solution of this utility model, the extension plate is fixedly connected to a pad in the second transmission mechanism. The pad corresponds to the position of the pressure roller. By setting the pad, the stability of the stator lamination of the roller press motor can be increased.

[0011] As a preferred technical solution of this utility model, an electric push rod is fixedly connected to one side of the extension plate, and a temporary limiting plate is fixedly connected to the output end of the electric push rod. The temporary limiting plate can be driven by the electric push rod to provide support for the rotating plate.

[0012] This invention has the following advantages: by setting an extension plate and a second transmission mechanism, and with the help of a rotatable rotating rod and rotating plate, the contact plate and buffer pad can be driven to adsorb the motor stator plates. Then, the motor stator plates are adsorbed and moved to the second transmission mechanism. The distance sensor and pressure roller can then roll the motor stator plates, which can improve the stamping quality of the motor stator plates, reduce the time increase caused by manual handling, and improve stamping efficiency.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figure 1-3 The high-efficiency precision motor stator lamination stamping machine shown includes a fixed plate 1, a first motor, a first transmission mechanism 2, a fixed die 3, a connecting plate 4, a first screw 5, and a moving die 6. The first transmission mechanism 2 can drive the motor stator lamination sheet to move. After stamping, the motor stator lamination sheet is in... Figure 1The first transmission mechanism 2 on the right side moves continuously. An extension plate 7 is fixedly connected to one side of the fixed plate 1, and a second motor is fixedly connected to one side of the extension plate 7. The second motor drives the second transmission mechanism 8 to rotate, which can cause the stamped motor stator laminations to move. The second transmission mechanism 8 is rotatably connected to the extension plate 7. A slide groove 9 is opened on the upper side of the extension plate 7. A third motor is fixedly connected to one side of the extension plate 7 at the slide groove 9. The third motor drives the second screw 10 to rotate, which can cause the moving plate 11 to move. It can cooperate with the rotation of the rotating rod 12 and the rotating plate 13 to form a mechanical action, thereby causing the contact plate 14 and the buffer pad 15 to move onto the fixed mold 3. The output end of the third motor is fixedly connected to the second screw 10. A movable plate 11 is threaded onto the second screw 10. A third motor is fixedly connected to the movable plate 11. A rotating rod 12 is fixedly connected to the output end of the third motor. A rotating plate 13 is fixedly connected to the rotating rod 12. An air pump is fixedly connected to one side of the rotating plate 13. A contact plate 14 is fixedly connected to the bottom side of the air pump. A cavity 20 is opened in the contact plate 14. The air pump draws air from the cavity 20 to form a negative pressure adsorption, which facilitates the adsorption of the motor stator plates. With the cooperation of the second screw 10 and the third motor, the motor stator plates are placed on the second transmission mechanism 8. A buffer pad 15 is fixedly connected to the bottom end of the contact plate 14. Through holes are evenly opened on the bottom sides of the contact plate 14 and the buffer pad 15. The cavity 20 communicates with the through holes.

[0019] Among them, a support plate 16 is fixedly connected to one side of the extension plate 7, and an adjusting rod 17 is threadedly connected to the support plate 16. A pressure frame 18 is rotatably connected to the bottom end of the adjusting rod 17. The pressure frame 18 contacts the extension plate 7, and a pressure roller 19 is rotatably connected inside the pressure frame 18. Rotating the adjusting rod 17 can cause the pressure frame 18 and the pressure roller 19 to press down, thereby improving the stamping quality of the motor stator by rolling the motor stator plates.

[0020] Among them, a distance sensor 22 is uniformly fixedly connected to one side of the bottom end of the support plate 16. The distance sensor 22 corresponds to the second transmission mechanism 8. By setting the distance sensor 22 to monitor the distance between the motor stator lamination and the distance sensor 22, the stamping quality of the motor stator lamination is screened.

[0021] The extension plate 7 is fixedly connected to the pad 21 inside the second transmission mechanism 8. The pad 21 corresponds to the position of the pressure roller 19. By setting the pad 21, reverse support can be provided to improve the quality of the motor stator laminations.

[0022] Among them, an electric push rod 23 is fixedly connected to one side of the extension plate 7, and a temporary limiting plate 24 is fixedly connected to the output end of the electric push rod 23. The extension of the electric push rod 23 causes the temporary limiting plate 24 to contact the rotating plate 13, thereby providing rotational support for the rotating plate 13.

[0023] Working principle: The motor stator sheet to be stamped moves on the first transmission mechanism 2, and then is stamped by the relative movement of the moving mold 6 and the fixed mold 3. When the stamping is completed, the second motor drives the second screw 10 to rotate, and causes the moving plate 11, rotating rod 12 and rotating plate 13 to move. Then the contact plate 14 and the buffer pad 15 contact the motor stator sheet on the fixed mold 3, and provide adsorption under the action of the air pump. At this time, the electric push rod 23 retracts and the temporary limiting plate 24 moves synchronously. Then the third motor drives the rotating rod 12, rotating plate 13 and contact plate 14 to rotate, thereby picking up the motor stator sheet and placing it on the second transmission mechanism 8 for movement. Then the adjusting rod 17 is rotated and drives the pressure frame 18 and pressure roller 19 to roll the stamped motor stator sheet. At the same time, the distance sensor 22 provides monitoring, which can inspect the stamped motor stator sheet, improve the stamping quality of the motor stator sheet and reduce the time for manual handling.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
