Embodiment Construction
[0029] The method of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0030] A method for preparing a permanent magnet assembly, comprising the steps of:
[0031] a. Take the guide plate 1 with a hole and the guide rod 2 with a nut at one end (such as figure 1 , 2 shown), the holes on the guide plate 1 are arranged in rows (the number of holes is determined by the specific assembly requirements), and the guide rod 2 penetrates into the holes;
[0032] b. Insert the first permanent magnet 3 into each guide rod 2 to form the first group of permanent magnets, absorb the first group of permanent magnets to the guide plate 1, and the adjacent permanent magnets 3 are mutually adsorbed or contact each other together (as in image 3 shown);
[0033] c. Insert the second permanent magnet, the third permanent magnet, ... etc. on each guide rod 2 in turn to form the second set of permanent magnets, the third set of permanent mag...

The invention relates to the technical field of permanent-magnets, in particular to a method for preparing a permanent-magnet assembly, and solves the problems that the conventional method for assembling permanent-magnets with different magnetic field directions into a permanent-magnet assembly manually has potential safety hazard and low efficiency. The method for preparing the permanent-magnet assembly comprises the following steps that: a, a guide plate (1) with holes and guide rods (2) of which one ends are provided with screw caps are taken, holes in the guide rod (1) are arranged in rows, and the guide rods (2) are penetrated into the holes; and b, a first permanent-magnet is penetrated into each guide rod to form a first group of permanent-magnet, the first group of the permanent-magnet is attracted to the guide plate, and the adjacent permanent-magnets are attracted or contacted with each other. The method is reasonable in design; and the permanent-magnet assembly is prepared by the method, a series of tools such as the guide plate, the guide rods, a two-way position adjusting clamp, a shaping tool and the like are used instead of hand-operated assembly, so that the production efficiency of the permanent-magnet assembly is improved.
Description
technical field [0001] The invention relates to the technical field of permanent magnets, in particular to a method for preparing a permanent magnet assembly. Background technique [0002] The technical development of permanent magnets is changing with each passing day, and the requirements for the size and uniformity of the surface magnetic field strength are getting higher and higher. The existing single permanent magnet materials cannot meet the requirements in many aspects, so by combining multiple magnetic blocks together The way (permanent magnet assembly) makes the magnetic field lines between the magnets accumulate, so as to realize the requirements for the magnetic field, but this brings a series of assembly problems. [0003] At present, the assembly method of permanent magnet assemblies for assembling magnetic levitation train tracks, large-area uniform magnetic field devices, etc. is usually to manually assemble multiple permanent magnet blocks together, which ha...
