Description

Technical Field

[0001] This utility model relates to the field of punching technology, and in particular to a punching device for rotor laminations. Background Technology

[0002] Rotor laminations are the core components that make up the rotor core of an electric motor. They are usually made of silicon steel sheets and their design directly affects the electromagnetic performance, mechanical strength and efficiency of the motor. Punching is a key process in its manufacturing, and its main purposes include forming magnetic circuit channels, fixing permanent magnets, reducing weight and optimizing heat dissipation.

[0003] Patent CN212019107U discloses a rotor lamination punching device. It includes a stamping bracket bolted to one side of the top of a base, a hydraulic press slidably connected to one side of the stamping bracket, a stamping rod base bolted to one side of the hydraulic press, a stamping rod inserted into one side of the stamping rod base, a lamination cutter bolted to the top of one side of the stamping rod, and a punching cutter bolted to the top of the stamping rod. When using this patent for punching, the rotor is fixed to the stamping base by passing it through it. The hydraulic press is activated, driving the stamping rod downwards, thus enabling the punching cutter and lamination cutter to work simultaneously. However, this existing patent still has some shortcomings in practical use. Because the existing patent only relies on the stamping base to fix the rotor, and the center opening of different rotor models is not consistent, there will be a large gap between the rotor and the stamping base. During stamping, the rotor's position is easily offset, resulting in eccentric punching and affecting the punching quality.

[0004] Therefore, there is a need to provide a punching device for rotor laminations with an automatic fixing function. Utility Model Content

[0005] To overcome the shortcomings of existing patents that rely solely on a stamping base to fix the rotor, and where the center opening of different rotor models is inconsistent, resulting in a large gap between the rotor and the stamping base, which can easily cause the rotor to shift during stamping, leading to eccentric punching and affecting the punching quality, this utility model provides a punching device for rotor laminations with an automatic fixing function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a punching device for rotor laminations, comprising a processing base, a cylinder, a punching assembly, a worktable, a placement base, and a servo motor. The processing base is equipped with a cylinder, and the punching assembly is mounted on the cylinder's extension rod. The processing base is equipped with a worktable, and a servo motor is installed within the worktable. A placement base is mounted on the output shaft of the servo motor. The device also includes an electric guide rail, an electric slider, a mounting rod, and a positioning plate. The processing base is equipped with an electric guide rail, and an electric slider is mounted on the electric guide rail. The electric slider slides on the electric guide rail, and a mounting rod is mounted on the electric slider. A positioning plate is fixedly connected to the mounting rod.

[0007] Furthermore, it is particularly preferred that the device also includes a fixed frame, a guide rod, a screw, a dual-axis motor, a sliding plate, and a fixed seat. The fixed frame is fixedly connected inside the worktable, the guide rod is fixedly connected to the fixed frame, the dual-axis motor is mounted on the fixed frame, and a screw is mounted on each of the two output shafts of the dual-axis motor. The screw rotates on the fixed frame, and a sliding plate is threaded onto the screw. The sliding plate slides on the guide rod, and a fixed seat is mounted on the output shaft of the motor.

[0008] In addition, it is particularly preferred that the device also includes a material drop seat and a guide seat, with the material drop seat fixedly connected to the worktable and the guide seat fixedly connected to the material drop seat.

[0009] Furthermore, it is particularly preferred that the machining base also includes a limiting frame, which is fixedly connected to and connected to the machining base.

[0010] In addition, it is particularly preferred that a soft pad is included, with the soft pad embedded in the positioning plate.

[0011] Furthermore, it is particularly preferred that the material dropper be trapezoidal.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By activating the electric guide rail, the electric slider is driven to move along the electric guide rail. While the electric slider moves, it drives the mounting rod and positioning plate to move, so that the positioning plate is inserted into the central groove of the placement seat. This allows the placement seat and positioning plate to automatically fix the rotor, thereby preventing the rotor from moving during punching and ensuring punching accuracy and quality.

[0013] 2. By starting the dual-axis motor, the two output shafts of the dual-axis motor drive the screws on both sides to rotate synchronously. The screws drive the sliding plates on themselves to slide inward along the guide rod, so that the sliding plates are inserted into the socket of the fixed seat. This locks the angle of the output shaft of the servo motor, thereby preventing the placement seat from rotating and ensuring the punching quality.

[0014] 3. The waste material after stamping falls into the trapezoidal material feeding seat through the stamping hole and is automatically discharged by the inclined surface, which can avoid the accumulation of waste material. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] Example 1: A punching device for rotor laminations, see reference. Figures 1-8As shown, the assembly includes a machining base 1, a cylinder 2, a punching assembly 3, a worktable 4, a placement base 5, and a servo motor 6. The machining base 1 has punching holes. The cylinder 2 is bolted to the top of the machining base 1. The punching assembly 3 is mounted on the telescopic rod of the cylinder 2. The punching assembly 3 consists of a punch, a fixing plate, and guide rods. The punch is mounted on the telescopic rod of the cylinder 2, and a fixing plate is fixedly connected to the outside of the punch. Two guide rods are fixedly connected to the fixing plate and slide on the machining base 1. The worktable 4 is mounted on the left side of the machining base 1. The bottom of the worktable 4 is bolted to the bottom. The machine tool has a servo motor 6, and a mounting base 5 is installed on the output shaft of the servo motor 6. The mounting base 5 is located above the worktable 4. The rotor is clamped on the ring of the mounting base 5. The machine tool also includes an electric guide rail 7, an electric slider 8, a mounting rod 9, and a positioning plate 10. The electric guide rail 7 is bolted to the upper left side of the machining base 1. The electric slider 8 is mounted on the electric guide rail 7 and slides on the electric guide rail 7. The mounting rod 9 is mounted on the electric slider 8. The positioning plate 10 is welded to the bottom of the mounting rod 9. When the positioning plate 10 moves downward, it is clamped into the central groove of the mounting base 5.

[0026] See Figure 1 and Figure 4 As shown, it also includes a soft pad 11, which is embedded in the positioning plate 10 and contacts the rotor.

[0027] When using this device, first, the rotor is secured to the placement seat 5. Then, by activating the electric guide rail 7, the electric slider 8 is driven to move along the electric guide rail 7. Simultaneously, the electric slider 8 moves the mounting rod 9 and the positioning plate 10, causing the positioning plate 10 to engage in the central groove of the placement seat 5. This automatically secures the rotor to the placement seat 5 and the positioning plate 10, preventing the rotor from shifting during punching and ensuring punching accuracy and quality. The soft pad 11 contacts the rotor, reducing impact and vibration and protecting the rotor surface. After securing, the cylinder 2 is activated. The extension of the telescopic rod 2 causes the punching assembly 3 to move downward, so that the punch on the punching assembly 3 punches the rotor. The waste material after punching is discharged from the punching hole on the processing seat 1. When it is necessary to adjust the rotor angle, the electric slider 8 is controlled to move in the opposite direction along the electric guide rail 7, so that the mounting rod 9 and the positioning plate 10 are reset. Then the servo motor 6 is started. The output shaft of the servo motor 6 drives the placement seat 5 and the rotor on it to rotate, thereby adjusting the rotor angle. After adjusting to the appropriate angle, the electric slider 8 is operated again to fix the rotor with the positioning plate 10, and then the subsequent punching operation can be performed.

[0028] Example 2: Based on Example 1, refer to Figure 6 and Figure 7As shown, it also includes a fixed frame 12, a guide rod 13, a screw 14, a dual-axis motor 15, a sliding plate 16, and a fixed seat 17. The fixed frame 12 is installed inside the worktable 4 by welding. The guide rod 13 is fixedly connected to the right side of the fixed frame 12. The dual-axis motor 15 is installed on the left side of the fixed frame 12 by bolts. Screws 14 are installed on both output shafts of the dual-axis motor 15. The screws 14 rotate on the fixed frame 12. The sliding plate 16 is threaded on the screw 14. The sliding plate 16 slides on the guide rod 13. The fixed seat 17 is installed on the output shaft of the servo motor 6. Multiple insertion holes are evenly spaced on the fixed seat 17. When the sliding plate 16 moves inward, it can be inserted into the insertion holes of the fixed seat 17.

[0029] While adjusting the rotor angle, the output shaft of the servo motor 6 drives the fixed base 17 to rotate. After rotating to the specified angle, the dual-axis motor 15 is started. The two output shafts of the dual-axis motor 15 drive the screws 14 on both sides to rotate synchronously. The screws 14 drive the sliding plate 16 on itself to slide inward along the guide rod 13, so that the sliding plate 16 is inserted into the insertion hole of the fixed base 17. This locks the angle of the output shaft of the servo motor 6, thereby preventing the placement seat 5 from rotating and ensuring the punching quality. When it is necessary to adjust the angle of the placement seat 5 again, the output shaft of the dual-axis motor 15 is reversed, so that the screws 14 drive the sliding plate 16 to move outward and disengage from the fixed base 17.

[0030] See Figure 1 and Figure 8 As shown, it also includes a material drop seat 18 and a guide seat 19. The material drop seat 18 is fixedly connected to the right side of the worktable 4, and the guide seat 19 is fixedly connected to the material drop seat 18.

[0031] See Figure 1 and Figure 8 As shown, the material discharge seat 18 is trapezoidal to facilitate the discharge of waste materials.

[0032] See Figure 1 and Figure 8 As shown, it also includes a limiting frame 20, which is fixedly connected to and connected to the processing seat 1. The limiting frame 20 is located above the unloading seat 18.

[0033] When the waste material falls through the punching hole of the processing seat 1, the punched waste material falls into the trapezoidal discharge seat 18 through the punching hole and is automatically discharged by the inclined surface. The guide seat 19 limits the flow of the waste material to avoid accumulation. The limit frame 20 restricts the direction of the waste material splashing to ensure that it falls accurately into the discharge seat 18.

[0034] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
