Abstract
The invention discloses a device for identifying magnetizing directions of radial non-magnetizing cylindrical (circular) anisotropic magnets. The device comprises a main plate, wherein the main plate is made of non-magnetic material, the main plate is provided with a plurality of circular holes for placing the cylindrical (circular) magnets with the to-be-identified magnetizing direction, square holes for fixing the magnetized magnets are symmetrically arranged on both sides of the circular holes, the centers of the circular holes and the square holes are positioned on one straight line, the diameter of each circular hole is slightly greater than the outer diameter of each cylindrical (circular) magnet with the to-be-identified magnetizing direction, and then each cylindrical (circular) magnet with the to be identified magnetizing direction can freely rotate in the holes. When the device for identifying the magnetizing direction of the radial non-magnetizing cylindrical (circular) anisotropic magnets is used for identifying the magnetizing directions of the anisotropic magnets, the end surface of the magnet with the to be identified magnetizing direction can be free from a concave groove, so the processing technology is simplified, the identification of the magnetizing direction is accurate, the qualified rate of the identification of the magnet magnetizing is effectively improved, the production period is shortened, and the production cost is reduced.
Description
Technical field
The present invention relates to anisotropic radially magnetizing circular column (ring) class permanent magnet product direction of magnetization marking field not, be specifically related to a kind of radially identity device of magnetizing circular column (ring) the class anisotropy magnet direction of magnetization not.
Background technology
Aborning, in assembling process, can effectively identify the direction of magnetization in order to make radially not magnetizing circular column (ring) series products, guarantee correct assembling.A lot of motor producers will radial oriented permanent magnet end face center when design cylinder (ring) series products by direction of magnetization recessing, permanent magnet manufacturer employing square is cut rectangular bars, is ground with moulding and wear into cylinder with strong grinding machine again after slotting like this.This processing technology easily causes the product end surface unfilled corner to scrap, and the course of processing unavoidably causes groove direction and the actual direction of magnetization to depart from, and working (machining) efficiency is low, and scrappage is high, has increased production cost.
Summary of the invention
A kind of radially identity device of magnetizing circular column (ring) the class anisotropy magnet direction of magnetization not that the purpose of this invention is to provide a kind of direction of magnetization that can identify accurately, fast magnetizing circular column product not.
Radially magnetizing circular column (ring) class anisotropy magnet direction of magnetization identity device not of the present invention, comprise the mainboard of magnetic conductive material not, described mainboard is provided with several for the circular hole of cylinder (ring) the class magnet of placing the direction of magnetization to be identified, is provided with for the fixing square hole of charged magnet at the monosymmetric of described circular hole; The center of described circular hole and square hole is on same straight line; The aperture of described circular hole is slightly larger than the external diameter of cylinder (ring) the class magnet of the direction of magnetization to be identified, and cylinder (ring) the class magnet of the direction of magnetization to be identified can be rotated in circular hole freely.
Be respectively equipped with a blend stop at the two ends of described mainboard, described blend stop is provided with for the step of determining the marking-out rule position, and the step interface of described two steps at grade.
The spacing of the cross central line of described step interface and blend stop is suitable with the diameter of bow pen pen core.
Described mainboard is not magnetic conductive material of plastic plate or other.
Adopt of the present invention radially when the identity device of magnetizing circular column (ring) the class anisotropy magnet direction of magnetization is not carried out the sign of the anisotropy magnet direction of magnetization, no longer recessing of product end surface in the need sign direction of magnetization, simplified processing technology, direction of magnetization sign accurately, Effective Raise magnet magnetization sign qualification rate, shorten the production cycle, reduced production cost.
