[0002] A linear motor, also known as a linear motor, a linear motor, etc., includes three parts: a stator, a mover, and a support wheel for linear motion. It is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism.

[0003] In a split assembled mover iron core of an iron core linear motor mentioned in an existing Chinese patent publication (authorization publication number: CN213937714U), by using the split assembled mover iron core of the iron core linear motor designed above, when in use, a plurality of second iron cores are all installed in the U-shaped groove of the first iron core, and a plurality of coils are respectively installed on the plurality of second iron cores, realizing the separated setting of the mover of the iron core linear motor, which is convenient for disassembly; at the same time, the coils are automatically wound by a winding machine, effectively improving the winding full slot rate and increasing the motor performance.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following further describes the present utility model in detail with reference to the attached Figures 1-4 drawings.

[0029] An embodiment of the present utility model discloses a split moving iron core structure.

[0030] Referring to Figure 1 and Figure 2, A split moving iron core structure, including iron core one 1, inside which several iron cores two 2 are slidably arranged at equal intervals. Several fitting grooves 3 are arranged at equal intervals on the inner side of iron core one 1. A fitting block 4 is fixedly connected to the bottom of iron core two 2. The fitting block 4 is adapted to the fitting groove 3 and is slidably arranged with the fitting groove 3. A coil 6 is sleeved outside iron core two 2. A top plate 5 is fixedly connected to the top of iron core two 2. Clamping mechanisms are arranged on both sides of the top of iron core one 1.

[0031] During installation, first sleeve the coil 6 outside the iron core two 2. The top plate 5 can reduce the risk of the coil 6 moving upward and falling off. Then place the iron core one 1 inside the iron core two 2 and slide it. Through the sliding connection between the fitting block and the fitting groove 3, the iron core two 2 is installed in the appropriate position. At the same time, through the limit of the fitting block and the fitting groove 3, the risk of the fitting two shifting is reduced. The iron core two 2 can be quickly fixed through the clamping mechanism, thereby improving the stability of the iron core two 2.

[0032] Refer to Figure 3 and Figure 4 , The clamping mechanism includes fixing blocks 7 fixedly connected to both sides of the top of iron core one 1. A clamping seat 8 is fixedly connected to the top of the two fixing blocks 7. A vertical plate 9 is fixedly connected to the top of the top plate 5. A moving block 10 is fixedly connected to the side of the vertical plate 9 close to the clamping seat 8. A clamping groove 11 is opened inside the clamping seat 8. The moving block 10 is slidably arranged with the clamping groove 11. A contact block one 12 is fixedly connected to the end of the moving block 10 close to the clamping seat 8. A contact block two 13 is slidably arranged inside the clamping groove 11. The contact block one 12 abuts against the contact block two 13.

[0033] Among them, the contact surface between the contact block one 12 and the contact block two 13 is set as an inclined surface, and the contact surfaces of the contact block one 12 and the contact block two 13 are adapted to each other.

[0034] In addition, a connecting block 14 is fixedly connected to one side of the contact block two 13. A spring 16 is fixedly connected to the bottom of the connecting block 14. The bottom end of the spring 16 is fixedly connected to the inner wall of the clamping groove 11.

[0035] And, the side of the connecting block 14 away from the contact block two 13 penetrates through the clamping seat 8. A connecting groove 15 is opened on the outside of the clamping seat 8. The connecting block 14 is slidably arranged with the connecting groove 15. A bottom block 17 is fixedly connected to the outside of the clamping groove 11. A guiding column 18 is fixedly connected to the top of the bottom block 17. The top end of the guiding column 18 penetrates through the connecting block 14. The connecting block 14 is slidably connected to the guiding column 18.

[0036] In addition, a driving block 19 is fixedly connected to the top of the connecting block 14. A button 20 is fixedly connected to the top of the driving block 19.

[0037] When installing the second iron core 2, the second iron core 2 drives the vertical plate 9 to move. The movement of the vertical plate 9 drives the moving block 10 to move. The movement of the moving block 10 drives the first abutting block 12 to move, so that the moving block 10 and the first abutting block 12 enter the inside of the engaging groove 11. When the first abutting block 12 enters the inside of the engaging groove 11, it will abut against the second abutting block 13. Since the contact surface between the first abutting block 12 and the second abutting block 13 is set as an inclined surface, the second abutting block 13 moves downward. The downward movement of the second abutting block 13 compresses the spring 16, causing the spring 16 to generate elastic potential energy. When the first abutting block 12 moves away from the second abutting block 13, the elastic potential energy of the spring 16 is released, so that the first abutting block 12 limits and fixes the second abutting block 13, thereby fixing the second top iron core 2, effectively reducing the movement of the second iron core 2 during operation, keeping the second iron core 2 in a stable position, improving the running stability of the motor, and improving the motion accuracy of the linear motor;

[0038] When the second abutting block 13 moves downward, the connecting block 14 of the second abutting block 13 moves. Since the connecting block 14 is slidably connected to the guide post 18, the guide post 18 provides an additional support point for the second abutting block 13, enabling the connecting block 14 to maintain a correct movement trajectory when moving;

[0039] When the second iron core 2 needs to be removed, the staff presses the button 20 to make the driving block 19 move downward. The downward movement of the driving block 19 drives the connecting block 14 downward, thereby releasing the limit on the first abutting block 12, facilitating the removal of the first iron core 1 for maintenance and replacement.

[0040] Working principle: A coil 6 is sleeved outside the second iron core 2. The top plate 5 can reduce the risk of the coil 6 moving upward and falling off. Then, the first iron core 1 is placed inside the second iron core 2 and slides. Since the fitting block is slidably connected to the fitting groove 3, the second iron core 2 is installed in a suitable position. At the same time, due to the limitation of the fitting block and the fitting groove 3, the risk of the second fitting moving out of position is reduced. The downward movement of the second abutting block 13 compresses the spring 16, causing the spring 16 to generate elastic potential energy. When the first abutting block 12 moves away from the second abutting block 13, the elastic potential energy of the spring 16 is released, so that the first abutting block 12 limits and fixes the second abutting block 13, thereby fixing the second top iron core 2. The guide post 18 provides an additional support point for the second abutting block 13, enabling the connecting block 14 to move smoothly.
