Description

Technical Field

[0001] This utility model relates to the field of magnetization clamp technology, specifically to a neodymium iron boron magnet rapid magnetization clamp. Background Technology

[0002] Neodymium iron boron magnets, as the third generation of rare earth permanent magnet materials, have their core magnetic energy source in the anisotropic crystal structure formed during the sintering process. This structure gives the magnetic domains inside the magnet a highly ordered arrangement in a specific direction, but their magnetic potential can only be activated through a magnetization process. In industrial production, the magnet blank is initially oriented by a strong magnetic field during the pressing and forming stage, so that the easy magnetization axis of the magnetic powder particles is aligned along the preset direction. This step determines the final magnetization direction of the magnet.

[0003] Traditional magnetizing clamps often fail to achieve omnidirectional stable fixation of neodymium iron boron magnets. Some clamps use simple mechanical buckles or clamping methods in one direction. These methods are not only not secure enough, but also difficult to adapt to neodymium iron boron magnets of different shapes and sizes, resulting in poor stability and easy movement of the magnets. Utility Model Content

[0004] The purpose of this invention is to provide a rapid magnetization fixture for neodymium iron boron magnets to address the shortcomings of existing technologies and solve the problems mentioned in the background art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A rapid magnetization fixture for neodymium iron boron magnets includes a positioning disk. A bearing is fixedly mounted on the inner wall of the positioning disk. A rotating ring is mounted on the inner ring of the bearing. A hollow positioning ring is fixedly mounted on the inner wall of the rotating ring. Positioning sleeves are fixedly mounted at equal intervals through an opening on the inner wall of the hollow positioning ring. A piston plate is slidably connected to the inner wall of the positioning sleeve. A positioning rod is fixedly mounted on the outer wall of one end of the piston plate. A pressing disk is fixedly mounted on the outer wall of the other end of the positioning rod.

[0007] As a preferred embodiment of a rapid magnetization fixture for neodymium iron boron magnets, a rubber pad is glued to one side of the outer wall of the extrusion disc.

[0008] As a preferred embodiment of a rapid magnetization fixture for neodymium iron boron magnets, the top outer wall of the hollow positioning ring is fitted with a vertically upward-pointing air tube through an opening, and an air tube connector is fixedly provided at one end of the top of the air tube.

[0009] As a preferred embodiment of a rapid magnetization fixture for neodymium iron boron magnets, the bottom outer wall of the positioning disk has a first positioning hole with annular and equidistant openings, and the top outer wall of the rotating ring has two second positioning holes. A positioning rod is inserted into the inner wall of the second positioning hole, and the bottom end of the positioning rod is adapted to the inner wall contour of the first positioning hole.

[0010] As a preferred embodiment of a rapid magnetization fixture for neodymium iron boron magnets, the bottom outer wall of the positioning disk is fixed with equally spaced support legs.

[0011] As a preferred embodiment of a rapid magnetization fixture for neodymium iron boron magnets, a pressure sensor is installed on the top outer wall of the hollow positioning ring, and the detection end of the pressure sensor is located inside the hollow positioning ring.

[0012] The beneficial effects of this utility model are:

[0013] This invention utilizes gas filling to cause the piston plate to slide within the positioning sleeve, which in turn moves the positioning rod and the extrusion disc toward the neodymium iron boron magnet. The rubber pad on the extrusion disc contacts the magnet, and multiple extrusion discs simultaneously extrude and fix the neodymium iron boron magnet from different directions, forming a comprehensive and stable fixing system. This system can fix neodymium iron boron magnets of different sizes, greatly improving the stability of the magnets during the magnetization process and effectively preventing the magnets from moving during magnetization.

[0025] Example 1:

[0026] like Figures 1 to 4As shown, this embodiment provides a rapid magnetization fixture for neodymium iron boron magnets, including a positioning disk 1. A bearing 2 is fixedly installed on the inner wall of the positioning disk 1. A rotating ring 3 is disposed on the inner ring of the bearing 2, so that the rotating ring 3 can rotate around the bearing 2 within the positioning disk 1. A hollow positioning ring 4 is fixedly installed on the inner wall of the rotating ring 3. Positioning sleeves 5 are fixedly installed on the inner wall of the hollow positioning ring 4 through openings at equal intervals. A piston plate 6 is slidably connected to the inner wall of the positioning sleeve 5. A positioning rod 7 is fixedly installed on the outer wall of one end of the piston plate 6. A compression plate 8 is fixedly installed on the outer wall of the other end of the positioning rod 7. To increase the buffering and protection effect during compression, a rubber pad 9 is glued to one side of the outer wall of the compression plate 8.

[0027] Example 2:

[0028] Based on Embodiment 1, in this embodiment, an upwardly extending inflation pipe 10 is installed on the top outer wall of the hollow positioning ring 4 through an opening, and an inflation pipe connector 11 is fixedly installed at one end of the top of the inflation pipe 10 for connecting an external inflation device to inflate the hollow positioning ring 4.

[0029] A first positioning hole 12 is made in a ring-shaped pattern on the bottom outer wall of the positioning disk 1. Two second positioning holes are made on the top outer wall of the rotating ring 3. The positioning rod 13 is inserted into the second positioning hole, and the bottom end of the positioning rod 13 is adapted to the inner wall contour of the first positioning hole 12. When the rotating ring 3 rotates to the appropriate position, the positioning rod 13 is inserted into the corresponding first positioning hole 12, thereby fixing the rotating ring 3.

[0030] Example 3:

[0031] Based on Embodiment 1, this embodiment has equidistantly distributed support legs 14 fixedly installed on the bottom outer wall of the positioning disk 1, which facilitates the placement of this utility model in a designated position. A pressure sensor 15 is installed on the top outer wall of the hollow positioning ring 4, and the detection end of the pressure sensor 15 is located inside the hollow positioning ring 4 to detect the pressure inside the hollow positioning ring 4, so as to understand the squeezing effect of the extrusion disk 8 on the magnet.

[0032] The working principle and usage process of this utility model:

[0033] Refer to the instruction manual appendix Figure 1-4When using the clamp of this utility model, the neodymium iron boron magnet to be magnetized is first placed in the center of the positioning plate 1. The hollow positioning ring 4 is connected to the air pump through the air inflator 11. The air pump inputs gas into the hollow positioning ring 4. As the gas continues to enter, the pressure inside the hollow positioning ring 4 gradually increases, pushing the piston plate 6 to slide in the positioning sleeve 5, which in turn drives the positioning rod 7 and the extrusion plate 8 to move towards the neodymium iron boron magnet. The rubber pad 9 on the extrusion plate 8 contacts the magnet. At the same time, the pressure sensor 15 monitors the pressure inside the hollow positioning ring 4 in real time. The operator can adjust the air volume according to the pressure value to control the extrusion plate 8 to apply appropriate pressure to the neodymium iron boron magnet. By using multiple extrusion plates 8 to extrude and fix the neodymium iron boron magnet from multiple directions, the stability of the neodymium iron boron magnet magnetization process is greatly improved, and the movement of the neodymium iron boron magnet during the magnetization process is avoided.

[0034] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
