Embodiment Construction

[0024] The specific steps of a positioning assembly method for eliminating magnetic force are:

[0025] The first step is to build the degaussing device

[0026] Degaussing device, including: push-in assembly Ⅰ2, push-in assembly Ⅱ3, sleeve Ⅰ4, sleeve Ⅱ5, pillar Ⅰ12, pillar Ⅱ13, gasket, lead screw 11, bottom plate 1, front baffle 14, stator rotation assembly, magnetic force assembly , slip ring 9, tailgate 15 and guide rail 6.

[0027] The guide rail 6 is threaded with the base plate 1, the front baffle 14 is threaded with the base plate 1, and the rear baffle 15 is threaded with the guide rail 6. The front baffle 14 is fixed with the push-in assembly I2 by screws, and the rear baffle 15 is fixed with the push-in assembly II3 by screws. Leading screw 11 is connected with tailgate 15 bearings. A cylinder with roundness and circular run-out tolerance of 0.02 mm passes through the center holes of push-in assembly I2 and push-in assembly II3 in sequence. The sleeve I4 passes t...

Abstract

The present invention discloses a positioning assembling method for elimination of a magnetic field force. A degaussing system is established, a degaussing device is installed and adjusted, a magneticforce module (8) and a stator rotation module (7) are installed and adjusted, a slip ring (9) is installed, and the magnetic force module (8) and the stator rotation module (7) are adjusted to complete high-precision positioning assembling of parts with magnetic field forces. The positioning assembling method is simple in implementation, can ensure stable relative motion of a stator and a rotor of a disc-type motor, can satisfy assembling precision requirements and can greatly reduce a rejection rate of magnetic sheets in an assembling process.

Description

technical field [0001] The invention relates to a positioning assembly method, in particular to a positioning assembly method for eliminating magnetic force. Background technique [0002] The disc permanent magnet synchronous motor is a new type of structure and high performance servo motor developed in recent years. This kind of motor has also been developed in my country in recent years. It has a short axial dimension, light weight, small size and compact structure; the most notable features of this motor are , The moment of inertia of the rotor is small, the electromechanical time constant is small, the peak torque and stall torque are high, the torque-to-weight ratio is large, the low-speed operation is stable, and it has superior dynamic performance. Research on the assembly of components with magnetic force plays an important role in the performance of the disc permanent magnet synchronous motor. [0003] At present, for the assembly of components with magnetic force, ...
