Abstract
A precise process method of external surface of micro flanged bearing made of non-permeability magnetic material includes five procedures of making magnet conducting slice, mounting, conducting magnet, positioning and processing. An electromagnet hollow clip is used for mounting the magnet conducting slice (3), a small shaft (1) and the external ring of flanged bearing (2), and the two position norms respectively are: the end face of the magnet conducting slice and the small outside diameter of the external ring of non magnet conducting flanged bearing. When in mounting of the magnet conducting slice, the small shaft and the external ring of flanged bearing, the end face of the magnet conducting slice and the norm end face of the external ring of non magnet conducting flanged bearing have to be cleaned up to ensure the parallel of the two end faces. When the process is completed, the magnet conducting slice and the external ring of the non magnet conducting flanged ring are dismantled, and then the next parts are mounted, therefore, the process method of external ring of the non magnet conducting flanged ring becomes the process method of ferrule of normal flanged bearing.

In order to realize the foregoing invention purpose, the present invention has adopted following technical scheme:
The precision machining method of described non-magnetic conduct material minitype flange bearing outer surface comprises magnetic conduction sheet → assembling → magnetic conduction → location → processing, and its each operation is as follows:
1), magnetic conduction sheet: magnetic conduction sheet guarantees wearability through Quenching Treatment, and the flange outside diameter of its outside dimension and processed flanged bearing outer ring is measure-alike, and two end faces are parallel to each other poor≤1 μ m to guarantee and the perpendicularity of the little external diameter bus in flanged bearing outer ring; The magnetic conduction sheet width is in 2～3mm scope, and internal diameter is processed into internal thread, the internal diameter of the diameter of thread≤processed flanged bearing outer ring;
2), assembling: little axle has been fixed the magnetic conduction effect to magnetic conduction sheet by flanged bearing outer ring internal diameter and at its large end face; Little axle is partly formed by three, its optical axis external diameter and flanged bearing outer ring internal diameter cunning are joined, clearance control is in 0.01mm, length is less than 0.03～0.1mm of flanged bearing outer ring developed width, thread spindle diameter and magnetic conduction sheet internal thread connect, the 0.2mm～0.3mm of the non-magnetic conduction flanged bearing outer ring external diameter of the big end of little axle external diameter＜processed;
3), magnetic conduction: the magnetic conduction effect is played by bonding magnetic conduction sheet in the flanged bearing outer ring;
4), the location: adopt electric magnetic no-core clamp to process, the end face of two locating surface first electric magnetic no-core clamp molds on lathe, another is two supporting fulcrums of electric magnetic no-core clamp;
5), processing: two location benchmark after magnetic conduction sheet, little axle and the assembling of flanged bearing lasso are respectively: the end face of magnetic conduction sheet is one of them location benchmark, and another location benchmark is the little external diameter of flanged bearing outer ring.
Owing to adopted technical scheme as mentioned above, the present invention to have following positive superiority:
1, the part of this method design only has two parts, and one is magnetic conduction sheet, and another is a thread spindle, and part is simple in structure, so simple in structure;
2, this method is owing to adopt electric magnetic no-core clamp that the little external diameter of non-magnet material flanged bearing is processed, and processing performance is good;
