[0002] The motor core is an important component of the motor and is usually made of stacked silicon steel sheets. The main function of the core is to provide a magnetic circuit to help transfer and convert electromagnetic energy. The core material has a high magnetic permeability and can effectively reduce magnetic flux loss and improve efficiency when the motor is working.

[0003] In the process of machining the motor core, the core material needs to be precisely cut. Laser cutting is usually used, especially when high precision and complex shapes are required. Laser cutting can provide higher cutting accuracy and ensure the accuracy of the core size after cutting. For motor cores that require complex geometric shapes or high-precision holes, laser cutting can ensure the consistency between the design drawings and the actual processed shapes. Especially in some special-purpose motors (such as high-frequency motors, precision motors, etc.), laser cutting is required to process delicate structures.

[0004] In the prior art, the rotor ventilation slot plate inside the electronic core is mainly placed on a flat table during processing, and the edge of the rotor ventilation slot plate blank is clamped by a clamping device, and then the rotor ventilation slot plate blank is laser processed. However, most of the clamping devices use two cylinders to push and clamp, which makes it only suitable for cutting some thicker plates.

[0042] The working principle of the present invention is as follows: when the staff uses the device to perform laser cutting on the rotor ventilation slot plate blank, the staff places the rotor ventilation slot plate blank on the upper end of the placement seat 35, and then starts the drive motor 10 to drive the drive shaft 11 to rotate clockwise. The outer wall of the drive shaft 11 is threadedly connected with the inner wall of the movable cylinder 13, and the movable cylinder 13 moves downward, thereby driving the connecting rod 14 and the toothed plate 15 to move downward.

The second transmission gear 20 and the first transmission gear 17 rotate, thereby driving the second transmission shaft 19 and one end of the first transmission shaft 16 to rotate. Due to the setting of the one-way bearing at the center end of the second transmission shaft 19, the other end of the second transmission shaft 19 does not rotate. When one end of the first transmission shaft 16 rotates, the other end of the first transmission shaft 16 rotates, thereby driving the first transmission bevel gear 18 to rotate, and the first transmission bevel gear 18 is meshed and connected with the input bevel gear 18. The input bevel gear 18 rotates, thereby driving the first input shaft 23 to rotate, and the first input shaft 23 transmits kinetic energy to the first speed change gear box 22. After the first speed change gear box 22 increases the speed, it drives the first output shaft 25 to rotate.

The outer wall of the first movable shaft 27 is threadedly connected to the inner wall of the connecting plate 28, and the connecting plate 28 moves downward, thereby driving the movable plate 29 to move downward. However, before the movable plate 29 is initially moved, the staff did not install the multiple sets of movable rods 30 to the bottom end of the movable plate 29, so the displacement of the movable plate 29 did not affect the rotor ventilation slot plate blank; When the driving shaft 11 rotates, it drives the driving bevel gear 12 to rotate, and the driving bevel gear 12 is meshed and connected with the multiple sets of limit bevel gears 5, so the multiple sets of limit bevel gears 5 rotate, thereby driving the multiple sets of limit cylinders 5 to rotate, and the inner walls of the multiple sets of limit cylinders 5 are respectively threadedly connected with the outer walls of the multiple sets of telescopic columns 6, so the multiple sets of telescopic columns 6 are respectively displaced toward the four ends of the inner wall of the rotor ventilation slot plate blank, thereby driving the multiple sets of limit heads 7 to displace, so that the four ends of the inner wall of the rotor ventilation slot plate blank are respectively engaged with the multiple sets of limit slots 9, and the multiple sets of limit heads 7 limit and fix the rotor ventilation slot plate blank, turn off the driving motor 10, and start the laser emitting device 46 to cut one end of the rotor ventilation slot plate blank. At the same time, the staff installs the multiple sets of movable rods 30 to the bottom end of the movable plate 29; When one end of the rotor ventilation slot plate blank is cut, and the staff needs to adjust the cut end of the rotor ventilation slot plate blank, the drive motor 10 is started to drive the drive shaft 11 to rotate counterclockwise, thereby driving the multiple groups of limit heads 7 to move into the multiple groups of reserved slots 3, and releasing the limit fixation of the rotor ventilation slot plate blank; When the driving shaft 11 rotates, the movable cylinder 13 drives the tooth plate 15 to move upward, and the tooth plate 15 is meshed and connected with the first transmission gear 17 and the second transmission gear 20 respectively, and the first transmission gear 17 and the second transmission gear 20 rotate, and the one-way bearing is set at the center end of the first transmission shaft 16, and the other end of the first transmission shaft 16 does not rotate; When the second transmission gear 20 rotates, the second transmission shaft 19 is driven to rotate, thereby driving the second transmission bevel gear 21 to rotate, the second transmission bevel gear 21 is meshed and connected with the linkage bevel gear 32, the linkage bevel gear 32 rotates, driving the linkage shaft 31 to rotate, the linkage shaft 31 is connected with the second movable shaft 33 through a synchronous belt, the second movable shaft 33 rotates, driving the movable gear 34 to rotate, the movable gear 34 is meshed and connected with the first gear ring 36, the first gear ring 36 rotates, driving the placement seat 35 to rotate, thereby driving the rotor ventilation slot plate blank to be adjusted; When the placement seat 35 rotates, the multiple sets of input gears 43 are driven to move, and the multiple sets of input gears 43 are respectively meshed and connected with the second gear ring 44. The multiple sets of input gears 43 rotate, driving the multiple sets of second input shafts 42 to rotate. The multiple sets of second input shafts 42 transmit kinetic energy to the multiple sets of second speed change gear boxes 39 respectively. After the multiple sets of second speed change gear boxes 39 increase the speed, they drive the multiple sets of second output shafts 40 to rotate, thereby driving the multiple sets of fans 41 to rotate, so that airflow is generated inside the fixed pipe 37, and the airflow is discharged from the bottom ends of the multiple sets of fixed pipes 37 to the outer end of the placement seat 35, so that the multiple sets of suction cups 38 generate negative pressure, and the multiple sets of suction cups 38 adsorb the rotor ventilation slot plate blank to assist in fixing the rotor ventilation slot plate blank to prevent the rotor ventilation slot plate blank from being offset as the placement seat 35 moves; After the placement seat 35 drives the rotor ventilation slot plate blank to move, the driving motor 10 drives the driving shaft 11 to rotate clockwise, and the multiple sets of limit heads 7 limit and fix the rotor ventilation slot plate blank again. At the same time, the movable plate 29 drives the multiple sets of movable rods 30 to move downward, and the multiple sets of movable rods 30 separate the residual waste after cutting from the rotor ventilation slot plate blank, and the waste falls into the guide seat 47, and the guide seat 47 conducts the waste to the collection box 48 for collection.
