Description

Technical Field

[0001] This utility model relates to the field of magnetic steel assembly technology, and in particular to a magnetic steel assembly structure. Background Technology

[0002] Due to their stable magnetic field characteristics, magnets are widely used in motors, sensors, magnetic drive equipment and other fields. In most scenarios, the requirements of equipment for magnetic field strength, distribution pattern or overall size cannot be met by a single magnet. Therefore, multiple magnets need to be assembled into a combined structure according to specific rules.

[0003] When installing magnets, manual installation is generally used. It requires people to hold the magnets and install them one by one into the magnet slots of the rotor core. When the magnets reach a certain size, it is impossible to install them accurately and safely by hand. The labor intensity of the assembly workers is high. In addition, because the magnets are large in size and have a strong magnetic force, they are easy to break during assembly.

[0004] The existing patent (publication number: CN215528821U) discloses a magnet installation tool. The magnet installation tool provided by this utility model can install the magnet in the magnet slot simply by moving the telescopic drive component. It has a simple structure and is easy to use. It can accurately, safely and efficiently install the magnet into place.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the rotors proposed in these patents are not convenient for limiting the movement of magnets during the insertion and assembly process. As the number of magnets increases, the magnets tend to repel each other due to magnetic force, which can cause the rotor to rotate just as the magnets are about to be inserted into the rotor, making it inconvenient to insert the magnets into the rotor for assembly.

[0006] Therefore, a magnetic steel assembly structure is proposed. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a magnet assembly structure, including a base plate, a rotor body disposed on the top of the base plate, a first fixing cone fixedly connected to the top of the base plate, a second fixing cone disposed on the top of the first fixing cone, an assembly mechanism and a rotating mechanism disposed on the top of the base plate, a support plate disposed on the right side of the top of the base plate, and a magnet body disposed on the left side of the support plate;

[0009] The assembly mechanism includes a lead screw, a fixed plate, a support plate, two clamping plates, an electric telescopic rod, and a sliding sleeve. The lead screw is threaded into the inside of the fixed plate. The right side of the fixed plate is fixedly connected to the left side of the support plate. The right side of the support plate is fixedly connected to the left side of the sliding sleeve. The sliding sleeve is slidably fitted onto the surface of the support plate. The top of the left clamping plate is fixedly connected to the bottom of the support plate. The surface of the right clamping plate is fixedly connected to the left side of the telescopic end of the electric telescopic rod. The right side of the electric telescopic rod is fixedly connected to the left side of the sliding sleeve.

[0010] Preferably, the rotating mechanism includes a limiting screw, a T-shaped slider, and a sliding clip. The inner wall of the sliding clip is in movable contact with the surface of the base plate. The bottom of the T-shaped slider is fixedly connected to the top of the sliding clip. The limiting screw is threaded inside the sliding clip, and the left side of the limiting screw is in close contact with the surface of the base plate.

[0011] Preferably, the top and bottom of the base plate are provided with annular grooves, and the sliding card is slidably connected to the inner wall of the annular groove.

[0012] Preferably, a T-shaped groove is provided at the bottom of the support plate, the T-shaped slider is slidably connected inside the T-shaped groove, and a pull ring is fixedly connected to the right side of the support plate.

[0013] Preferably, a limiting block is fixedly connected to the front side of the support plate, and a locking screw is provided on the top of the limiting block. The bottom of the locking screw passes through the limiting block and is in close contact with the top of the T-shaped slider. The surface of the locking screw is connected to the internal thread of the limiting block.

[0014] Preferably, a limiting rod is fixedly connected to the top of the first fixed cone, the rotor body is movably sleeved on the surface of the limiting rod, the inner wall of the rotor body is in contact with the surface of the first fixed cone, the second fixed cone is threadedly sleeved on the surface of the limiting rod, the surface of the second fixed cone is in contact with the inner wall of the rotor body, and a screw block is fixedly connected to the top of the second fixed cone, the number of screw blocks is several and they are evenly distributed on the top of the second fixed cone.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application sets up an assembly mechanism, which uses a screw, a fixed plate, a support plate, a clamping plate, an electric telescopic rod, and a sliding sleeve to work together. The electric telescopic rod drives the clamping plate to clamp the magnet body. After the limit screw and locking screw are tightened, the support plate is stabilized and limited by friction. The screw moves down and pushes the support plate to make the sliding sleeve slide down, inserting the magnet body into the rotor assembly slot. Then the clamping plate is removed, and the remaining shorter magnet body is slowly hammered into the assembly slot using external tools to complete the assembly, ensuring that the magnet body is installed accurately and stably.

[0019] 2. This application incorporates a rotating mechanism consisting of a limiting screw, a T-shaped slider, and a sliding catch. The sliding catch rotates along the annular groove to adjust the position of the magnet body around the rotor body, and is locked in place by the limiting screw. The T-shaped slider slides in the T-shaped groove to adjust the position of the support plate to accommodate rotor bodies of different diameters, and is reinforced by the locking screw. The rotor body is stably clamped by the first and second fixed cones, and the limiting screw and locking screw stably limit the position of the support plate, ensuring the stability of the rotor body and the magnet body. This prevents the magnetic forces between the magnet bodies from repelling each other during assembly, which could cause the rotor body to rotate and affect insertion. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] A magnet assembly structure includes a base plate 1, a rotor body 2 is provided on the top of the base plate 1, a first fixed cone 10 is fixedly connected to the top of the base plate 1, a second fixed cone 11 is provided on the top of the first fixed cone 10, an assembly mechanism 6 and a rotating mechanism 8 are respectively provided on the top of the base plate 1, a support plate 7 is provided on the right side of the top of the base plate 1, and a magnet body 18 is provided on the left side of the support plate 7.

[0031] The assembly mechanism 6 includes a lead screw 601, a fixed plate 602, a support plate 603, two clamping plates 604, an electric telescopic rod 605, and a sliding sleeve 606. The lead screw 601 is threaded into the inside of the fixed plate 602. The right side of the fixed plate 602 is fixedly connected to the left side of the support plate 7. The right side of the support plate 603 is fixedly connected to the left side of the sliding sleeve 606. The sliding sleeve 606 is slidably fitted onto the surface of the support plate 7. The top of the left clamping plate 604 is fixedly connected to the bottom of the support plate 603. The surface of the right clamping plate 604 is fixedly connected to the left side of the telescopic end of the electric telescopic rod 605. The right side of the electric telescopic rod 605 is fixedly connected to the left side of the sliding sleeve 606.

[0032] In this embodiment: the rotor body 2 is fitted onto the limiting rod 4, so that its inner wall contacts the first fixed cone 10. Then, the second fixed cone 11 is threaded onto the limiting rod 4. The second fixed cone 11 is rotated by the screw block 12 or the insertion hole 13, which, together with the first fixed cone 10, clamps and fixes the rotor body 2, ensuring that it is perpendicular to the base plate 1 and coaxial with the limiting rod 4. The support leg 9 stably supports the base plate 1. Then, the magnet body 18 is placed between the two clamping plates 604. The external controller controls the extension of the electric telescopic rod 605, so that the two clamping plates 604 clamp the magnet body 18. The support plate 603 and the sliding sleeve 606 ensure stable clamping. When adjusting the position, the pull ring 15 is held to pull the sliding card 803 to rotate in the annular groove 5. After it is in place, the limiting screw 801 is tightened to fix it. The support plate is adjusted by sliding the T-shaped slider 802 in the T-shaped sliding groove 14. Position 7 is adapted to rotor bodies 2 of different diameters. After adjustment, tighten the locking screw 17 to fix it. After aligning with the assembly slot 3, use an electric wrench to turn the lead screw 601, causing it to move down and push the support plate 603, which in turn drives the sliding sleeve 606 to slide down, inserting the magnet body 18 into the assembly slot 3. Then, retract the electric telescopic rod 605 to remove the clamping plate 604. Use an external tool to knock in the remaining shorter part of the magnet body 18 to complete the assembly. During the process, both the rotor body 2 and the magnet body 18 are fixed, which facilitates insertion and assembly. This solves the problem in the existing patent that it is inconvenient to limit the rotor during the insertion and assembly of the magnet. As the number of magnets installed increases, the magnets are prone to mutual repulsion due to magnetic force, which can cause the rotor to rotate when the magnet is about to be inserted into the rotor, making it inconvenient to insert the magnet into the rotor for assembly.

[0033] Specifically, such as Figure 2 and Figure 4 As shown, the rotating mechanism 8 includes a limiting screw 801, a T-shaped slider 802, and a sliding clip 803. The inner wall of the sliding clip 803 is in movable contact with the surface of the base plate 1. The bottom of the T-shaped slider 802 is fixedly connected to the top of the sliding clip 803. The limiting screw 801 is threadedly connected inside the sliding clip 803. The left side of the limiting screw 801 is in close contact with the surface of the base plate 1.

[0034] Specifically, such as Figure 2 and Figure 4 As shown, the top and bottom of the base plate 1 are provided with annular grooves 5, and the sliding card 803 is slidably connected to the inner wall of the annular groove 5.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, a T-shaped groove 14 is provided at the bottom of the support plate 7, and a T-shaped slider 802 is slidably connected inside the T-shaped groove 14. A pull ring 15 is fixedly connected to the right side of the support plate 7.

[0036] Specifically, such as Figure 1 , Figure 4 and Figure 5As shown, a limiting block 16 is fixedly connected to the front side of the support plate 7. A locking screw 17 is provided on the top of the limiting block 16. The bottom of the locking screw 17 passes through the limiting block 16 and is in close contact with the top of the T-shaped slider 802. The surface of the locking screw 17 is connected to the internal thread of the limiting block 16.

[0037] In this embodiment: the rotating mechanism 8 cooperates with the annular groove 5 through the sliding card 803 to realize the flexible rotation of the magnet body 18 around the rotor body 2. The limit screw 801 can quickly fix the position. The T-shaped slider 802 cooperates with the T-shaped slide groove 14 to facilitate the adjustment of the radial position of the support plate 7 to adapt to rotor bodies 2 of different diameters. The locking screw 17 enhances the stability of the support plate 7. The pull ring 15 facilitates operation and improves the overall assembly flexibility and applicability.

[0038] Specifically, such as Figure 1 , Figure 2 and Figure 7 As shown, the top of the first fixed cone 10 is fixedly connected to a limiting rod 4, the rotor body 2 is movably sleeved on the surface of the limiting rod 4, the inner wall of the rotor body 2 is in contact with the surface of the first fixed cone 10, the second fixed cone 11 is threadedly sleeved on the surface of the limiting rod 4, the surface of the second fixed cone 11 is in contact with the inner wall of the rotor body 2, and a screw block 12 is fixedly connected to the top of the second fixed cone 11. The number of screw blocks 12 is several and they are evenly distributed on the top of the second fixed cone 11.

[0039] Specifically, such as Figure 2 As shown, the second fixed cone 11 has several insertion holes 13 inside, which are evenly distributed inside the second fixed cone 11.

[0040] Specifically, such as Figure 3 , Figure 6 and Figure 7 As shown, the rotor body 2 has several assembly slots 3 inside, and the bottom of the base plate 1 is fixedly connected with four support legs 9, which are symmetrically distributed at the bottom of the base plate 1. The bottom of the lead screw 601 is in contact with the top of the support plate 603.

[0041] In this embodiment: the first fixed cone 10 and the second fixed cone 11, together with the limiting rod 4, quickly position and firmly clamp the rotor body 2, ensuring its verticality and coaxiality. The screw block 12 and the insertion hole 13 facilitate labor-saving operation. The assembly groove 3 provides an installation position for the magnet. The support leg 9 ensures the overall stability. The lead screw 601 and the support plate 603 cooperate to realize the precise insertion of the magnet body 18, improving the assembly efficiency and accuracy.

[0042] Working principle: First, the rotor body 2 is movably fitted onto the surface of the limiting rod 4, so that its inner wall contacts the surface of the first fixed cone 10. Then, the second fixed cone 11 is threaded onto the surface of the limiting rod 4. By turning the screw block 12 or by inserting an external tool into the insertion hole 13, the second fixed cone 11 is rotated so that its surface contacts the inner wall of the rotor body 2. This, together with the first fixed cone 10, clamps and fixes the rotor body 2, ensuring that the rotor body 2 is perpendicular to the base plate 1 and coaxial with the limiting rod 4. The support leg 9 provides stable support for the base plate 1. Next, the magnet body 18 is moved to the side between the two clamping plates 604. The extension end of the electric telescopic rod 605 is extended by the external controller, driving the right clamping plate 604 to move to the left, and... The left clamping plate 604 tightly clamps the magnet body 18. The top of the left clamping plate 604 is fixedly connected to the bottom of the support plate 603, and the right side of the support plate 603 is fixedly connected to the left side of the sliding sleeve 606. The sliding sleeve 606 is slidably sleeved on the surface of the support plate 7 to ensure clamping stability. When the position of the magnet body 18 needs to be adjusted, since the sliding clip 803 is slidably connected to the inner wall of the annular groove 5 opened at the top and bottom of the base plate 1, the sliding clip 803 can be pulled by holding the pull ring 15 to make the magnet body 18 rotate around the rotor body 2 to any position. After rotating to the position, tighten the limiting screw 801 so that its left side is in close contact with the surface of the base plate 1. The sliding clip 803 is limited and fixed by friction. At the same time, the T-shaped slider 802 is slidably connected to the support plate 7. Inside the T-shaped groove 14 at the bottom of plate 7, the position of support plate 7 can be adjusted by sliding the T-shaped slider 802 to accommodate different sizes of rotor body 2 and magnet body 18. After adjustment, tighten the locking screw 17 that passes through the limiting block 16 and is in close contact with the top of the T-shaped slider 802. The friction between the locking screw 17 and the T-shaped slider 802 limits the position of support plate 7. When the magnet body 18 is rotated to align with the assembly groove 3 inside the rotor body 2, use an external electric wrench to rotate the screw 601 threaded inside the fixing plate 602. The right side of the fixing plate 602 is fixedly connected to the left side of support plate 7. The screw 601 moves down and pushes the support plate 603 downward, causing the sliding sleeve 606 to slide downward along the surface of support plate 7, thereby clamping the magnet body 18. The magnet body 18 is inserted into the assembly slot 3. Then, the exposed parts of the magnet are processed, and the electric telescopic rod 605 is retracted to remove the clamping plate 604. Using an external tool, the remaining shorter part of the magnet body 18 is slowly tapped into the assembly slot 3 to complete the assembly. Because both the rotor body 2 and the magnet body 18 are fixed during the assembly process, it is easy to insert and assemble the magnet body 18 with the rotor body 2. This solves the problem in existing patents where it is inconvenient to limit the movement of the rotor during magnet insertion and assembly, and as the number of magnets increases, the magnets tend to repel each other due to magnetic force, causing the rotor to rotate just before the magnet is inserted, making it inconvenient to insert the magnet into the rotor for assembly. It should be noted that...The rotor body 2, the magnet body 18, and the electric telescopic rod 605 are all existing, published, and mature technologies. The electric telescopic rod 605 is powered by an external power source; its basic mechanism will not be elaborated here. Furthermore, any content not described in detail in this specification is prior art known to those skilled in the art.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
