The invention relates to an accurate positioning method for permanent magnet spindle processing. A permanent magnet rotor comprises a permanent magnet spindle, a permanent magnet and an iron core, the permanent magnet and the iron core are sleeved on the permanent magnet spindle together, a magnetic field shielding device comprises a magnetic field shielding layer, a shielding layer protection cover and an end cap, a threaded rod is used to pass through a silicon steel sheet layer and the end cap, two ends of the threaded rod are screwed up by clamp nuts, and accordingly, the magnetic field shielding device is integrated via fastening; the radial direction of the end cap is provided with an adjusting hole with inner threads, an adjusting bolt with outer threads passes through the adjusting hole, the magnetic field shielding device is fixed on the permanent magnet rotor, the position and angle of an axis of the magnetic field shielding device are adjusted by the adjusting bolt so as to lead the axes of the magnetic field shielding device and the permanent magnet rotor to be in a same straight line. The accurate positioning method can guarantee the magnetic field shielding device and the permanent magnet rotor to be coaxial, and realizes the accurate positioning of the magnetic field shielding device when a permanent magnet spindle is processed.
Description
technical field [0001] The invention relates to a precise positioning of a magnetic field shielding device during machining of a permanent magnet shaft, in particular to a method and a device capable of adjusting the position of the axis of the magnetic field shielding device during machining of a permanent magnet shaft. Background technique [0002] When the machine tool processes the permanent magnet shaft, in order to prevent the magnetic field generated by the permanent magnet rotor from generating magnetic force on the machine tool and affecting the machining accuracy of the machine tool, it is necessary to put a magnetic field shielding device on the periphery of the permanent magnet rotor to shield the magnetic field generated by the permanent magnet rotor. Thereby avoiding the unfavorable factors caused by the magnetic field generated by the permanent magnet rotor to the machine tool and the three-dimensional coordinate loss measurement. However, when the magnetic fi...
