[0003] For a magnet whose outer ring is a semicircle in the magnetic field system, the outer ring loses its restrictive effect on the magnet, and the magnet not only has radial displacement but also circumferential and upward displacement during the assembly process, so if the existing assembly of the entire cylindrical magnetic field is used Systematic method to assemble the cascade magnetic field system, not only the assembly is difficult, the assembly safety factor is low, but the efficiency will be greatly reduced

Description
technical field [0001] The invention relates to a magnet technology, in particular to an assembly device and an assembly method of a cascade magnetic field system. Background technique [0002] The magnetic field system is one of the important systems and components in the magnetic refrigeration equipment. The performance of the magnetic field is directly related to the performance of the magnetic refrigerator. The performance of the magnetic field depends on two aspects, one is design and the other is assembly. Generally, the magnetic field system is composed of a yoke and multiple magnets, and the magnets are assembled in a certain order in the space formed by the yoke. At present, the magnetic field system commonly used in magnetic refrigerators is a cylindrical magnetic field. The assembly sequence follows Halbach's rotation theory, and a central core and multiple fan-shaped molds similar to the shape of the magnet are used for assembly. Since the outer ring of this ma...
