The invention discloses a magnetizing device, which comprises a magnetizing coil frame, a magnetizing coil and an external connecting terminal, wherein the magnetizing coil is wound on the magnetizing coil frame tightly; the external connecting terminal is in phase electrical connection with the magnetizing coil; the magnetizing coil comprises a first coil and a second coil of the same radius andnumber of windings; the space between the first coil and the second coil is equal to the radius of the first coil; the direction of electrified current is the same as that of the second coil; two ends of the first coil and the second coil and the magnetizing area between the two ends generate uniform magnetic fields; the magnetizing coil frame is provided with a hollow cavity; the inside of the cavity is provided with a magnetizing fixture; and the magnetizing fixture fixes a magnetized object at the geometric center position of the first coil and the second coil. Compared with the existing magnetizing device, the magnetizing device can greatly improve the magnetizing drift angle of the magnetized object, thereby satisfying the magnetizing requirement of precision magnetism components with strict requirement on the magnetizing drift angle.
Description
technical field [0001] The invention relates to a magnetizing device, in particular to a magnetizing device which requires a magnetized body to have a higher magnetization deflection angle. Background technique [0002] The traditional magnet magnetization device uses the magnetic field generated by a single hollow solenoid coil for magnetization. This magnetization method can meet most of the industrial needs. When using the magnetizing device to magnetize the object to be magnetized, the magnetized direction of the object to be magnetized will not be completely consistent with the direction required to be magnetized by the object to be magnetized. There is an angle between the two, which is generally called the magnetization declination. Due to the limitations of the hollow solenoid coil itself, the traditional magnetizing device made of a single hollow solenoid coil cannot guarantee a uniform magnetic field in the magnetizing area, which is an important factor that causes...
