Description

Technical Field

[0001] This utility model relates to the field of magnetic ring magnetization technology, specifically a micro-motor magnetic ring magnetization device. Background Technology

[0002] Constant current magnetization of microelectromagnetic rings is a magnetization technique used to increase the magnetic strength of magnetic materials. It magnetizes the microelectromagnetic ring by using a constant current. Specifically, constant current magnetization is achieved by placing the microelectromagnetic ring in a constant direct current magnetic field. This current generates a constant magnetic field that magnetizes the microelectromagnetic ring and increases its magnetic strength.

[0003] According to application number CN202322199608.9, an automatic magnetizing device for a unipolar radiating magnetic ring belongs to the field of magnet magnetization technology. The automatic magnetizing device of this utility model includes a support frame, on which a rotating platform and a lifting assembly are mounted. The rotating platform drives the magnetic ring to rotate. The lifting assembly is equipped with an N-pole permanent magnet and an S-pole permanent magnet, with a gap between the two permanent magnets for the ring portion of the magnetic ring to pass through.

[0004] The magnetization device in the above case has low magnetization efficiency. After a magnetic ring is magnetized, it is removed from the clamp on the placement platform, and then the next magnetic ring is placed on the placement platform and clamped and fixed by the clamp. It is impossible to continuously magnetize the magnetic ring, which affects the work efficiency. Therefore, we provide a micro motor magnetic ring magnetization device. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A micro-motor magnetic ring magnetization device includes a base plate 1 and a rotatable annular plate 2 disposed above the base plate 1. Four placement plates 3 are disposed on the top of the annular plate 2, the bottom of the placement plates 3 is in contact with the top of the annular plate 2, a magnetic ring body 4 is disposed on the top of the placement plates 3, the bottom of the magnetic ring body 4 is in contact with the top of the placement plates 3, and two movable arc-shaped limiting blocks 5 are disposed on the top of the placement plates 3 and inside the magnetic ring body 4.

[0023] It also includes a servo motor 6, which is mounted on the top of the base plate 1. The top of the output shaft of the servo motor 6 is fixedly connected to the bottom of the annular plate 2. A slot 7 is provided on the top of the annular plate 2 at the position corresponding to the placement plate 3. A locking block 8 that matches the slot 7 is fixedly connected to the bottom of the placement plate 3. Both the slot 7 and the locking block 8 are square in shape. The bottom of the locking block 8 passes through the slot 7 and extends into it, contacting the inner wall of the slot 7. A fastening bolt 9 that is threadedly connected to the locking block 8 is provided on the bottom of the annular plate 2 at the position corresponding to the locking block 8.

[0024] Specifically, loosen the fastening bolt 9, and then pull the placement plate 3 upward. The placement plate 3 causes the locking block 8 and the locking groove 7 to separate, so that the placement plate 3 can be removed from the annular plate 2, making it convenient to maintain and repair the structure on the placement plate 3.

[0025] Two support plates 23 are fixedly connected to the top of the base plate 1. Steel balls 24 are rotatably connected in the grooves at the top of the support plates 23. The top of the steel balls 24 rolls in contact with the bottom of the annular plate 2. By setting the support plates 23 and steel balls 24, the stability of the rotational movement of the annular plate 2 is improved, and the steel balls 24 reduce the friction generated when they come into contact with the annular plate 2.

[0026] The top of the placement plate 3 has a fixing groove 10 that communicates with the magnetic ring body 4. Two fixing blocks 11 are fixedly connected to the bottom of the inner wall of the fixing groove 10. Fixing rods 12 are fixedly connected to the sides of the two fixing blocks 11 located on the same side but far apart from each other. One end of the fixing rod 12 near the inner wall of the fixing groove 10 is fixedly connected to the inner wall of the fixing groove 10. A moving block 13 is slidably connected to the surface of the fixing rod 12. The surface of the moving block 13 slides in contact with the inner wall of the fixing groove 10. A buffer spring 14 is sleeved on the surface of the fixing rod 12. An adjusting block 15 is fixedly connected to the top of 13. The top of the adjusting block 15 passes through the fixing groove 10 and the magnetic ring body 4 from bottom to top and extends into the interior of the magnetic ring body 4. The side of the adjusting block 15 near the arc-shaped limiting block 5 is fixedly connected to the arc-shaped limiting block 5 through the connecting block 16. Push blocks 17 are fixedly connected to the sides of the two moving blocks 13 on the same side and away from each other. The side of the push block 17 away from the moving block 13 passes through the fixing groove 10 and extends to its outside. A push plate 18 is fixedly connected to the side of the push block 17 away from the moving block 13.

[0027] As shown in the figure, the buffer spring 14 has the force to drive the moving block 13 and the arc-shaped limiting block 5 away from the fixed block 11, which improves the contact effect between the arc-shaped limiting block 5 and the inner wall of the magnetic ring body 4.

[0028] A support frame 19 is fixedly connected to the top left side of the base plate 1. An electric push rod 20 is fixedly connected to the support frame 19. A base 21 is fixedly connected to the bottom end of the electric push rod 20. A magnetizing component 22 is fixedly connected to the bottom of the base 21.

[0029] Furthermore, the magnetization assembly 22 includes a magnetic field coil 221 and a power supply 222. The power supply 222 is installed on top of the magnetic field coil 221. A controller is fixedly connected to the left side of the support frame 19. The servo motor 6, the electric push rod 20 and the magnetization assembly 22 are electrically connected to the controller.

[0030] The servo motor 6 drives the annular plate 2 to rotate, allowing multiple magnetic ring bodies 4 on the annular plate 2 to rotate. After the magnetic ring body 4 on the left is magnetized, the next magnetic ring body 4 can be quickly rotated to the underside of the magnetization component 22 for magnetization, improving magnetization efficiency. Through the cooperation of the arc-shaped limiting block 5, fixing groove 10, fixing block 11, fixing rod 12, moving block 13, buffer spring 14, adjusting block 15, connecting block 16, push block 17 and push plate 18, the magnetic ring body 4 placed on the placement plate 3 is conveniently limited and fixed, ensuring the stability of the magnetic ring body 4 during magnetization and improving practicality.

[0031] In use, the electric push rod 20 is activated, and the electric push rod 20 drives the magnetizing component 22 to move downward through the base 21, so that the magnetic field coil 221 completely covers the magnetic ring body 4 located on the left. Then, the voltage of the power supply 222 is adjusted according to the specifications of the magnetic ring body 4 and the magnetization requirements to generate an appropriate magnetic field strength, thereby magnetizing the magnetic ring body 4. Magnetic ring magnetization is a publicly available technology, so it will not be described in detail here.

[0032] After the magnetic ring body 4 on the left side is magnetized, the electric push rod 20 drives the magnetizing component 22 to move upward, and the servo motor 6 drives the ring plate 2 to rotate 90 degrees counterclockwise, so that the magnetic ring body 4 on the rear side moves to the downward position of the magnetizing component 22, and the electric push rod 20 drives the magnetizing component 22 to move downward to magnetize the magnetic ring body 4.

[0033] After magnetization, the magnetic ring body 4 moves to the front of the annular plate 2, pushing the two push plates 18 closer to each other. The push plates 18 drive the moving block 13 to move closer to the fixed block 11 through the push block 17. The moving block 13 squeezes the buffer spring 14 and moves. The moving block 13 drives the arc-shaped limiting block 5 away from the magnetic ring body 4 through the adjusting block 15 and the connecting block 16, so that the arc-shaped limiting block 5 and the inner wall of the magnetic ring body 4 are separated. Then, the magnetic ring body 4 after magnetization is pulled upward, so that the magnetic ring body 4 and the placement plate 3 are separated. Then, the magnetic ring body 4 to be magnetized is replaced. Then, the push plate 18 is released. Through the restoring force of the buffer spring 14, the buffer spring 14 drives the arc-shaped limiting block 5 away from the fixed block 11, so that the arc-shaped limiting block 5 is in close contact with the inner wall of the magnetic ring body 4, thus limiting and fixing the magnetic ring body 4.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
