Description

Technical Field

[0001] This application relates to the technical field of permanent magnet processing, and in particular to a fixture for processing neodymium iron boron magnets. Background Technology

[0002] Neodymium iron boron (NdFeB) is a high-performance magnetic material widely used in electronics, new energy, and other fields. Its processing precision and quality directly affect product performance. During NdFeB processing, the stability and flexibility of the fixtures are crucial. They must ensure precise positioning of the material during cutting, grinding, and other processing steps to avoid processing errors caused by displacement, while also being adaptable to NdFeB materials of different specifications and shapes.

[0003] Regarding the aforementioned related technologies, the inventors believe that existing NdFeB processing fixtures have many shortcomings. Some fixtures have simple structures, making it difficult to achieve stable clamping of NdFeB materials from all directions, resulting in easy loosening of the materials during processing. Other fixtures are inconvenient to adjust, unable to quickly adapt to NdFeB materials of different sizes, and have a low degree of automation, increasing manual operation costs and labor intensity, affecting processing efficiency and quality. Therefore, there is an urgent need for a new type of NdFeB processing fixture to solve these problems. Thus, to solve the above problems, this application provides a NdFeB processing fixture. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a fixture for processing neodymium iron boron.

[0005] This application provides a fixed fixture for processing neodymium iron boron, including a base, a clamping assembly, and a driving assembly. An electric telescopic rod is fixedly connected to the surface of the base, and a horizontal plate is fixedly connected to the output end of the electric telescopic rod. Two fixed plates are symmetrically fixedly connected to the surface of the horizontal plate. A rotating shaft is rotatably connected to the opposite side of the two fixed plates through a bearing, and a U-shaped plate is fixedly connected to the opposite side of the two rotating shafts.

[0006] Preferably, the clamping assembly includes a screw rotatably connected to the top wall of the C-shaped plate, the bottom end of the screw extending into the interior of the C-shaped plate and rotatably connected to a pressure plate.

[0007] Preferably, one end of one of the rotating shafts, away from the C-shaped plate, extends to the other side of the fixed plate and is fixedly connected to a driven gear. The drive assembly includes a servo motor fixedly connected to the outer wall of the fixed plate. The output end of the servo motor is fixedly connected to a half gear, and the outside of the half gear meshes with the driven gear.

[0008] Preferably, a limiting block is fixedly connected to the rear side wall of the horizontal plate, a limiting rod is slidably connected inside the limiting block, and the bottom end of the limiting rod is fixedly connected to the surface of the base.

[0009] Preferably, the rear sidewall of the pressure plate is in close contact with the inner wall of the web of the U-shaped plate.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. Automated adjustment and precise positioning: This fixture uses an electric telescopic rod on the base surface to raise and lower the horizontal plate, which can be flexibly adjusted according to the height requirements of the NdFeB material to achieve rapid positioning; the servo motor drives the half gear and driven gear to mesh, driving the rotating shaft and the shaped plate to rotate, which can automatically realize the flipping operation of the NdFeB material, reduce manual operation, and improve processing efficiency and accuracy.

[0012] 2. Multi-directional stable clamping: The screw in the clamping assembly cooperates with the pressure plate. By rotating the screw, the pressure plate can be moved downward to vertically press and fix the NdFeB material. At the same time, the rear side wall of the pressure plate is tightly fitted with the inner wall of the web of the C-shaped plate, which restricts the horizontal movement of the pressure plate. This achieves multi-directional stable clamping of the NdFeB material, ensuring that the material will not be displaced during processing and guaranteeing processing quality.

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] Example 1:

[0020] A fixture for processing neodymium iron boron, as shown in the reference. Figure 1 - Figure 4The device includes a base 1, a clamping assembly, and a drive assembly. An electric telescopic rod 2 is fixedly connected to the surface of the base 1. A horizontal plate 3 is fixedly connected to the output end of the electric telescopic rod 2. Two fixed plates 4 are symmetrically fixedly connected to the surface of the horizontal plate 3. A rotating shaft 5 is rotatably connected to the opposite side of the two fixed plates 4 through a bearing. A U-shaped plate 6 is fixedly connected to the opposite side of the two rotating shafts 5.

[0021] Specifically, base 1 serves as the fundamental support component of the entire fixture, providing a stable mounting surface for subsequent components. The electric telescopic rod 2 is fixed to the surface of base 1. When the fixture position needs to be adjusted according to the height of the NdFeB material, the power to the electric telescopic rod 2 is turned on. Its internal motor drives the lead screw to rotate, and through the lead screw and nut transmission mechanism, the motor's rotational motion is converted into the linear extension and retraction motion of the telescopic rod. Since the horizontal plate 3 is fixedly connected to the output end of the electric telescopic rod 2, the horizontal plate 3 will rise and fall vertically synchronously with the telescopic rod, achieving rapid and precise adjustment of the overall height of the fixture. This ensures it can accommodate NdFeB materials of different thicknesses, achieving rapid positioning.

[0022] Reference Figure 1 and Figure 4 The clamping assembly includes a screw 7 rotatably connected to the top wall of the C-shaped plate 6. The bottom end of the screw 7 extends into the interior of the C-shaped plate 6 and is rotatably connected to a pressure plate 8. The rear side wall of the pressure plate 8 is tightly fitted to the inner wall of the web of the C-shaped plate 6.

[0023] Specifically, in the clamping assembly, a screw 7 rotatably connects to the top wall of the C-shaped plate 6, forming a threaded engagement with the top wall of the C-shaped plate 6. When an operator uses a wrench or other tools to rotate the screw 7, based on the principle of thread transmission, the screw 7 will move up and down axially. The pressure plate 8, rotatably connected to the bottom end of the screw 7, gradually approaches and presses against the neodymium iron boron material placed inside the C-shaped plate 6 as the screw 7 moves downward, achieving a firm vertical clamping and fixation of the neodymium iron boron material. It is worth mentioning that the rear side wall of the pressure plate 8 is tightly fitted to the inner wall of the web of the C-shaped plate 6. This fitting design forms a horizontal constraint on the pressure plate 8. During the clamping of the neodymium iron boron material, even when subjected to external forces from different directions, the tightly fitted structure can limit the horizontal movement of the pressure plate 8, preventing the pressure plate 8 from shifting or shaking. The combination of vertical clamping and horizontal restriction achieves multi-directional stable clamping of NdFeB materials, ensuring that the materials remain stable during processing such as cutting and grinding, and that the processing quality is not affected by displacement.

[0024] Reference Figure 1 and Figure 4One of the rotating shafts 5 extends from the end away from the shaped plate 6 to the other side of the fixed plate 4 and is fixedly connected to the driven gear 9. The drive assembly includes a servo motor 10 fixedly connected to the outer wall of the fixed plate 4. The output end of the servo motor 10 is fixedly connected to a half gear 11, and the outside of the half gear 11 meshes with the driven gear 9.

[0025] Specifically, in the drive assembly, the servo motor 10 on the outer wall of the fixed plate 4 serves as the power source. Its precise speed and direction control capabilities are crucial for achieving automated adjustment. After the servo motor 10 starts, its output drives the half gear 11 to perform circular motion. Since the half gear 11 only has teeth on a portion of its circumference and its diameter is equal to that of the driven gear 9, when the half gear 11 rotates, its teeth periodically mesh with the driven gear 9. During the meshing phase, the half gear 11 transmits power to the driven gear 9 through its teeth, causing the driven gear 9 to rotate; during the non-meshing phase, the driven gear 9 remains stationary. Through the precise control of the rotation angle and time by the servo motor 10, the driven gear 9 can drive the rotating shaft 5 to rotate by a specific angle, thereby enabling the C-shaped plate 6 to achieve precise angle adjustment and complete the automatic flipping or angle adjustment operation of the NdFeB material. This intermittent meshing transmission method not only meets the diverse requirements of different processing techniques for material angles but also avoids the over-adjustment problem that may result from continuous rotation, ensuring processing accuracy and stability.

[0026] Reference Figure 2 and Figure 3 A limiting block 12 is fixedly connected to the rear side wall of the horizontal plate 3, and a limiting rod 13 is slidably connected inside the limiting block 12. The bottom end of the limiting rod 13 is fixedly connected to the surface of the base 1.

[0027] Specifically, the limiting block 12 fixed to the rear side wall of the horizontal plate 3 and the limiting rod 13 fixed to the surface of the base 1 constitute a limiting structure. The limiting block 12 has a sliding channel inside that matches the shape and size of the limiting rod 13. When the electric telescopic rod 2 drives the horizontal plate 3 to move vertically up and down, the limiting block 12 slides along the limiting rod 13 within the sliding channel. The limiting rod 13 provides precise guidance for the sliding of the limiting block 12, restricting the horizontal plate 3's freedom in the horizontal direction, allowing it to move only in the vertical direction.

[0028] The implementation principle of the fixed fixture for NdFeB processing in this embodiment is as follows: The fixed fixture for NdFeB processing uses base 1 as a stable support foundation, providing a bearing platform for the entire fixture system. The electric telescopic rod 2 and the servo motor 10 are both electrically connected to an external power source via a switch. When it is necessary to adjust the height of the fixture to adapt to NdFeB materials of different thicknesses, the electric telescopic rod 2 plays a key role. The electric telescopic rod is preferably of type LX600. When the electric telescopic rod 2 is started by the switch, its internal motor drives the lead screw to rotate. With the help of the lead screw and nut transmission mechanism, the rotational motion is converted into linear telescopic motion, thereby driving the horizontal plate 3, which is fixedly connected to the output end, to rise and fall vertically. At the same time, the limiting block 12 on the rear side wall of the horizontal plate 3 slides along the limiting rod 13 on the base 1 to ensure accurate and stable lifting and achieve rapid positioning. In terms of angle adjustment, the servo motor 10 on the outer side wall of the fixed plate 4 serves as the power source. The servo motor 3 is preferably of type HBS57. When the servo motor 10 is started by the switch, it drives the half gear 11 to rotate. Half gear 11 intermittently meshes with driven gear 9 fixed at one end of rotating shaft 5. Because their diameters are equal, during the meshing phase, driven gear 9 is driven to rotate, thereby rotating rotating shaft 5 and the connected C-shaped plate 6, realizing automatic flipping or angle adjustment of NdFeB material to meet diverse processing needs. For fixing NdFeB material, screw 7 in clamping assembly is threaded with the top wall of C-shaped plate 6. When the operator rotates screw 7, screw 7 drives pressure plate 8 to move axially, pressing the material placed in C-shaped plate 6. At the same time, the rear side wall of pressure plate 8 is tightly fitted with the inner wall of the web of C-shaped plate 6, restricting the horizontal displacement of pressure plate 8, realizing multi-directional stable clamping from vertical and horizontal directions, ensuring that the material does not shift during processing, and ensuring processing accuracy and quality. The external thread opening angle of screw 7 is 20 degrees, and the thread self-locking condition must meet the following formula calculation: self-locking condition = friction coefficient × tan (helix angle) ≥ 1.
