Abstract

The invention relates to a clamp for assembling an annular extruding permanent magnet magnetic system and an assembly method thereof. The clamp comprises an inner ring shaft of which two ends are respectively provided with external thread sections, a plurality of nylon sleeves of which the bore diameter is greater than the external diameter of the inner ring shaft, a nylon positioning sleeve which is matched with the external thread sections of the inner ring shaft and is machined with internal threads, a nylon limit sleeve which is matched with the external thread sections of the inner ring shaft and is machined with the internal threads and is provided with an external baffle ring at one end of the inner ring shaft, a non-magnetic conducting magnet steel protective cylinder and a non-magnetic conducting stainless steel pressing cylinder which is machined with a plurality of threaded holes around the circumference of the non-magnetic conducting stainless steel pressing cylinder, wherein puller bolts are arranged in the threaded holes; wall thicknesses of sleeve sections of the nylon sleeve, the nylon positioning sleeve and the nylon limit sleeve are greater than the height of assembled strip magnet steel; the inner diameter of the magnet steel protective cylinder is greater than outer diameters of the sleeve sections of the nylon sleeve, the nylon positioning sleeve and the nylon limit sleeve; and the inner diameter of the non-magnetic conducting stainless steel pressing cylinder is greater than the outer diameter of the magnet steel protective cylinder.

Description

technical field [0001] The present invention relates to the technical field of assembling the magnetic system of various permanent magnet magnetic separators, which is fan-shaped magnetic steel and spliced ​​along the ring direction, and specifically relates to a fixture for assembling a ring-shaped extruded permanent magnet magnetic system and its assembly method. Background technique [0002] At present, permanent magnet magnetic separation equipment at home and abroad has the advantages of simple structure, high efficiency, and low power consumption. Because of the optimized combination of permanent magnet magnetic system, it is highly efficient, economical, and energy-saving. favored by other industrial sectors. The magnetic system is the key component of the magnetic separator, and its magnetic performance directly affects the technical performance and separation effect of the magnetic separator. Therefore, the optimal design of the magnetic system is very important. ...
