[0020] Example 1

[0021] like Figures 1-4 As shown in the figure, the punching device for DC motor production proposed in this embodiment includes a support plate 1, a turntable 2, a soundproof cover 5, an upper baffle 6, a drilling mechanism, and a driving device.

[0022] The support plate 1 has two first circular holes 101, and a circular grid 20 is provided inside one of the first circular holes 101. A waste box 19 is detachably installed at the bottom of the support plate 1, and the waste box 19 is located directly below the circular grid 20. A support column 7 is provided at the center of the support plate 1, and the support column 7 is movable through the turntable 2. A support frame 3 is provided at the bottom of the support plate 1. Furthermore, a PLC controller 9 is installed on the support frame 3, and the PLC controller 9 supports the automatic control of the device during operation.

[0023] The turntable 2 has multiple second circular holes 201 arranged in a ring array along its upper edge. There are at least three second circular holes 201. This arrangement ensures that the device has at least three independent feeding, processing, and unloading stations. Multiple limit blocks 18 are installed on the inner side of each of the multiple second circular holes 201. The turntable 2 is rotatably mounted on the support plate 1. A power assembly for driving the turntable 2 to rotate is installed on the support column 7. The power assembly includes a servo motor 15, a gear 16, and a gear ring 17. The servo motor 15 is mounted on the support column 7, and the gear 16 is mounted on the output shaft of the servo motor 15. A rotating tube 14 is provided at the center of the turntable 2. The gear ring 17 is mounted on the outer periphery of the rotating tube 14 and meshes with the gear 16. Starting the servo motor 15 can drive the gear 16 to rotate. The rotation of the gear 16 drives the gear ring 17 to rotate, and the rotation of the gear ring 17 drives the rotating tube 14 and the turntable 2 to rotate.

[0024] The soundproof cover 5 has openings at both the top and bottom. The soundproof cover 5 is located above the turntable 2. A mounting plate 8 connects the soundproof cover 5 and the support column 7. The soundproof cover 5 passes through the mounting plate 8. The upper baffle 6 is located on the mounting plate 8 and covers the soundproof cover 5. The diameter of the upper baffle 6 is larger than the inner diameter of the soundproof cover 5. This arrangement allows the upper baffle 6 to completely cover the upper opening of the soundproof cover 5 when it moves horizontally.

[0025] The drilling mechanism is mounted on the upper baffle 6. The drilling mechanism includes a first servo cylinder 10, a motor mounting bracket 21, a drive motor 22, and a drill bit 23. The motor mounting bracket 21 is located inside the soundproof enclosure 5. The first servo cylinder 10 is mounted on the upper baffle 6, and its output shaft is connected to the motor mounting bracket 21. The drill bit 23 is rotatably mounted on the motor mounting bracket 21. The drive motor 22 is mounted on the motor mounting bracket 21, and its output shaft is connected to the drill bit 23. The drive motor 22 can drive the drill bit 23 to rotate to achieve drilling. Cylinder 10 can adjust the lifting height of drill bit 23, making the drilling depth adjustable; the drive device is mounted on mounting plate 8 to drive the upper baffle 6 to move horizontally. The drive device includes a second servo cylinder 11 and a third servo cylinder 12. A slide plate 13 is slidably mounted on mounting plate 8. The second servo cylinder 11 is mounted on slide plate 13 and its output shaft is connected to the upper baffle 6. The third servo cylinder 12 is mounted on mounting plate 8 and its output shaft is connected to slide plate 13. The extension and retraction direction of the third servo cylinder 12 is perpendicular to the extension and retraction direction of the second servo cylinder 11.

[0026] The working principle of this technical solution is as follows:

[0027] The DC motor rear end cover to be processed is placed inside the second circular hole 201 adjacent to the feeding area, and multiple limiting blocks 18 are used to limit the rear end cover. The power component drives the turntable 2 to rotate intermittently, and the single rotation angle of the turntable 2 is 360 / N, where N is the number of second circular holes 201. After the second circular hole 201 containing the rear end cover moves to the inside of the soundproof cover 5, the rear end cover is drilled by the drilling mechanism. Furthermore, the drive device can drive the upper baffle 6 to move horizontally, and the upper baffle 6 then drives the punching mechanism to move, thereby adjusting the drilling. Position; During this process, the soundproof cover 5, the upper baffle 6, and the waste box 19 together form a relatively sealed space, which can prevent the processing debris from splashing outwards and greatly reduce the noise generated during operation. The processing debris falls into the inside of the waste box 19 through the holes of the circular grille 20. When the turntable 2 rotates again, the turntable 2 can scrape the remaining debris on the circular grille 20 back into the inside of the waste box 19, preventing debris accumulation. It should be noted that the waste box 19 and the support plate 1 are connected by screws or threads. If a threaded connection is used, refer to Figure 4 As shown, an internal threaded ring is installed at the bottom of the support plate 1, and a thread that matches the internal threaded ring is provided on the outer periphery of the waste box 19.

[0028] After processing is completed, the turntable 2 continues to rotate. At this time, the processed workpiece moves to the unloading area. The second circular hole 201 is aligned with the first circular hole 101. Under the action of gravity, the workpiece is discharged through the first circular hole 101, realizing the function of automatic unloading.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, the punching device for DC motor production proposed in this embodiment, compared with the first embodiment, also includes a belt conveyor 4. The belt conveyor 4 is located below the first circular hole 101 on one side, which is located on the side away from the circular grid 20. The workpiece falling through the first circular hole 101 can fall onto the belt conveyor 4 and be transported to the next work station, thus realizing the purpose of automatic transfer.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
