As for the flange bottom plate 3 and the frame body 1, the fixed connection can be realized through the large ring body 32 and a plurality of second fasteners penetrating through the large ring body 32. Based on the structural characteristics of the flange bottom plate 3 and the assembling relationship of the small ring 31 between the frame body 1 and the guide rod body 2, the plurality of second fastening members can be distributed around the mounting hole in the frame body 1. Any one second fastener penetrates through the axial end face of the large ring body 32 and is locked in the frame body 1.

For the plurality of second fastening members annularly distributed around the mounting hole, in the guide bar of the steel plate magnetic centering device, the fixed base plate 4 may be disposed in an area surrounded by all the second fastening members, or the size of the area surrounded by all the second fastening members is larger than that of the fixed base plate 4, so that any one of the second fastening members penetrating into the large ring body 32 and the frame body 1 does not penetrate into the fixed base plate 4.

The guide bar of the steel plate magnetic centering device provided by the invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts.
