processing method of oblique multi pole radial magnetic fixture

by AOMag | post a comment

The magnetic poles of the conventional magnetic material are parallel to the axial direction, as disclosed before, a method in which the wire can be reliably fixed The magnetic jigs are arranged parallel to each other. There has not been a magnetizing fixture capable of magnetizing the cylindrical permanent magnet to the outer circumference or the inner circumference. The main reason is that the traditional clamping body is a solid material of the whole block, and the cylindrical permanent magnet of the oblique multi-pole radial magnetic clamping fixture hole should be a spiral, in a cylinder with a mechanical processing method is very Difficult to process a spiral wire hole, it is difficult to produce oblique magnetized multi-pole radial magnetic fixture.

It is an object of the present invention to provide a magnetizing jig and a method of machining a cylindrical permanent magnet in a diametrically magnetized magnetic pole to fill a void. The technical proposal of the invention is that the oblique multi-pole radial magnetic clamping fixture is realized by radial stacking of 10-500 layers of cylindrical or cylindrical solid sheet material into a cylindrical clamp body or a cylindrical clamp body 4-36 helical wire holes passing through the solid sheet material of each layer are radially evenly distributed in the outer circumference of the cylindrical clamp body or the inner circumference of the cylindrical clamp body, and the spiral wire hole is facing The cylindrical permanent magnet is provided with an opening, a helical wire hole and an oblique distribution at an opening of 2 to 60 degrees, and a magnetizing wire is wound in the spiral wire hole. The number of layers of the solid sheet material is different depending on the different heights of the cylindrical permanent magnets to be magnetized. The solid sheet material is silicon steel, pure iron, bakelite or plastic, and has a thickness of 0.1 mm lmm. The cylindrical clamp body has a cylindrical diameter slightly smaller than the inner diameter of the cylindrical permanent magnet. The cylindrical clamp body has an inner circle diameter slightly larger than the outer diameter of the cylindrical permanent magnet. The shape of the spiral wire hole is circular, square, trapezoidal or other geometrical. The method comprises the following steps of: (1) selecting 10-500 cylindrical or cylindrical solid sheet material of the same size and thickness of 0.1mm lmm; (2) in the above- (3) according to the final required oblique angle divided by the total number of openings in the same direction as the outer circumference of the solid sheet material or the inner and outer circumferences, (4) the solid sheet is superimposed up and down, and the solid sheet of each of the following is opposed to the solid sheet immediately adjacent thereto, and the solid sheet is made on the basis of the center of the solid sheet, and the solid sheet (5) winding the magnetizing wire in the helical wire hole. (5) The spiral wire is wound in the helical wire hole. The invention realizes the radial magnetization of the oblique multi-magnetic pole to the outer circumference or the inner circumference of the cylindrical permanent magnet; and the processing is simple, the manufacturing is easy, the cost is low, and the wire hole has high precision.
