A mold for splicing annular magnetic tiles and a splicing method

Abstract

The invention discloses a mold and a splicing method for splicing annular magnetic tiles, comprising an outer hoop ring, a through hole is formed on the side of the outer hoop ring; an inner core column is arranged concentrically with the outer hoop ring , the inner stem includes a first cylinder and a second cylinder coaxially arranged, the first cylinder is located on the upper side of the second cylinder, and the outer diameter of the second cylinder is smaller than the The first cylinder, the lower end of the second cylinder is located in the outer hoop, the second cylinder cooperates with the outer hoop to form an annular accommodation chamber to accommodate a plurality of magnetic tiles, the guide groove It is located on the side of the first column to guide the magnetic tile into the annular accommodation cavity; the wrench is the same as to spread the adjacent magnetic tiles, and the end of the wrench enters the annular accommodation cavity through the through hole, and the wrench The width is greater than the width of the magnetic tile. It can complete the circular splicing of magnetic tiles, and has compact structure, low cost and high assembly precision.

Description

technical field [0001] The invention relates to the technical field of radial permanent magnet installation, in particular to a mold for splicing annular magnetic tiles and a splicing method. Background technique [0002] In the process of manufacturing and assembling linear oscillating compressors, installation problems of radially magnetized permanent magnets are often encountered. Now there are two common installation methods. One is the integral annular permanent magnet that is directly installed after central radiation magnetization. , this method is easy to assemble, but the radiation magnetization technology content is high, the cost of the magnetization mold is high, and the magnetization intensity is difficult to make the permanent magnet reach its own magnetic saturation strength; the other is after the radial parallel magnetization of the arc magnetic tile Use the corresponding molds for splicing and installation, and finally form a circular structure and the radi...

Problems solved by technology

[0002] In the process of manufacturing and assembling linear oscillating compressors, installation problems of radially magnetized permanent magnets are often encountered. Now there are two common installation methods. One is the integral annular permanent magnet that is directly installed after central radiation magnetization. , this method is easy to assemble, but the radiation magnetization technology content is high, the cost of the magnetization mold is high, and the magnetization intensity is difficult to make the permanent magnet reach its own magnetic saturation strength; the other is after the radial parallel magnetization of the arc magnetic tile Use the corresponding molds for splicing and installation, and finally form a circular structure and the radial magnetic field is approximately regarded as a circular radial shape. This method is less difficult to magnetize, and the permanent magnet magnetic tile is easy to reach magnetic saturation, so the surface magnetism is larger, which is conducive to improving compression. The power density of the compressor is the method widely used in the manufacture and assembly of compressor permanent magnets

However, after the magnetic tiles are magnetized, there is an attractive or repulsive force between them, which brings great difficulties to the splicing and assembly. In actual operation, it is easy to cause the magnetic steel to be scrapped, and the corresponding control mold structure is complex and the manufacturing cost is high. In the laboratory In R&D and enterprise pre-research occasions, there is no effective measure to solve the above problems in small batch manufacturing
