Description

Technical Field

[0001] This utility model relates to neodymium iron boron magnet technology, and more particularly to a neodymium iron boron magnet positioning fixture. Background Technology

[0002] Neodymium iron boron (NdFeB) magnets are tetragonal crystals formed from neodymium, iron, and boron. They are the second strongest permanent magnets currently known, after holmium magnets at absolute zero, and are the most commonly used rare-earth magnets, widely applied in various electrical products. However, current auxiliary positioning fixtures lack versatility, requiring different fixtures for different processing devices, thus increasing production costs. Furthermore, existing auxiliary positioning fixtures are complex in structure, expensive to manufacture, and cannot be reused multiple times. Therefore, improvements are needed to design a positioning fixture for NdFeB magnets that meets current application requirements. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model proposes a neodymium iron boron magnet positioning fixture.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A neodymium iron boron magnet positioning fixture, comprising:

[0006] The positioning base has symmetrical baffles and symmetrically arranged positioning components, the positioning components being arranged perpendicular to the baffles.

The lower end of the positioning component is hinged to the hinge seats via a hinge rod. An elastic element is provided between the pressure-applying component and the positioning base.

[0008] The positioning component has a guide end at its upper end, and the pressure-applying component has a guide groove in the middle that cooperates with the guide end.

[0009] In this neodymium iron boron magnet positioning fixture of the present invention, the driving component is an electromagnetic component, the pressure-applying component is made of magnetic metal material, and the driving component attracts the pressure-applying component after being energized.

[0010] In this neodymium iron boron magnet positioning fixture of the present invention, the lower end of the pressure-applying member is provided with a first extension end and a second extension end, a guide groove is formed between the first extension end and the second extension end, a guide opening is formed at the guide groove, and the guide end enters the guide groove through the guide opening.

[0011] In this neodymium iron boron magnet positioning fixture of the present invention, a first protrusion is provided on the first extension end.

[0012] In this neodymium iron boron magnet positioning fixture of the present invention, the positioning member is provided with a relief groove that cooperates with the first protrusion, and a guide slope is provided in the relief groove.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1 to 5As shown, this new type of neodymium iron boron magnet positioning fixture includes a positioning base 1. The positioning base 1 has symmetrical baffles 2 and symmetrically arranged positioning components 3. The positioning components 3 cooperate with the baffles 2 to position the neodymium iron boron magnet 4 in the center. The positioning components 3 are perpendicular to the baffles 2. Of course, according to actual needs, the baffles 2 can be replaced with the positioning components 3, thereby enabling the fourth positioning component 3 to position the neodymium iron boron magnet 4.

[0023] The positioning assembly 3 includes a mounting base 5, a driving component 6, a pressure applying component 7, and a positioning component 8. The mounting base 5 is mounted on the positioning base 1, and the driving component 6 is mounted on the mounting base 5. The driving component 6 has a recessed groove 9, and the mounting base 5 has a protrusion 10 that mates with the recessed groove 9, facilitating the up-and-down movement of the pressure applying component 7, which then resets under the elastic force of the elastic component 11. The lower end of the pressure applying component 7 has a positioning post 71 for positioning the elastic component 11.

[0024] The driving component 6 is an electromagnetic component, and the pressure-applying component 7 is made of a magnetic metal material. When the driving component 6 is energized, it attracts the pressure-applying component 7. The pressure-applying component 7 is provided with a second protrusion 12, and the driving component 6 attracts the second protrusion 12. A moving area 13 for the second protrusion 12 is formed between the driving component 6 and the second protrusion 12.

[0025] The positioning seat 1 is provided with symmetrical hinge seats 14, and the lower end of the positioning member 8 is hinged to the hinge seat 14 through the hinge rod 15. An elastic member 11, which is a spring, is provided between the pressure member 7 and the positioning seat 1.

[0026] The positioning member 8 has a guide end 16 at its upper end, and the pressure member 7 has a guide groove 17 in the middle that mates with the guide end 16. The pressure member 7 has a first extension end 18 and a second extension end 19 at its lower end, and the guide groove 17 is formed between the first extension end 18 and the second extension end 19. A guide opening 20 is formed at the guide groove 17, and the guide end 16 enters the guide groove 17 through the guide opening 20.

[0027] The first extension end 18 is provided with a first protrusion 21, and a first arc 22 is provided on the first protrusion 21. The second extension end 19 is provided with a second arc 23. The first arc 22 contacts the guide slope 24, and the second arc 23 cooperates with the guide arc surface 25, so that the guide end 16 can enter the guide groove 17.

[0028] The positioning member 8 is provided with a relief groove 26 that mates with the first protrusion 21, and a guide slope 24 is provided in the relief groove 26. The positioning member 8 is also provided with a positioning protrusion 27, which facilitates limiting the position of the neodymium iron boron magnet 4, and can also clamp the narrower neodymium iron boron magnet 4.

[0029] An extension portion 28 is provided on the guide end 16, which contacts the second extension end 19. The guide end 16 is also provided with a guide arc surface 25. The extension portion 28 can prevent the guide end 16 from detaching from the guide port 20.

[0030] When the driving component 6 is powered on, it will attract the pressure component 7, so that the guide end 16 enters the guide groove 17 under the guidance of the guide port 20, so that the upper end of the positioning component 8 is in an inclined state, which makes it easier to put the neodymium iron boron magnet 4 into the positioning seat 1, and limit it through the cooperation of the baffle 2 and the positioning component 3.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
