Problems solved by technology
At present, for the assembly of permanent magnet motor rotors, the prior art usually uses specific assembly machine tools. Although these machine tools in the prior art can fix the rotor to achieve stable assembly of the rotor and the stator, these machine tools are large in size and inconvenient to move. The equipment investment is high, and the assembly degree of the rotor and the stator needs to be manually observed during installation, which is inconvenient to operate

The present invention relates to the field of motor part assembling, especially to permanent magnet motor rotor assembling tool. The permanent magnet motor rotor assembling tool comprises an upper housing fixedly connected with a stator, the bottom portion of the upper housing is provided with an opening, the lower portion of the stator is provided with a screw rod rotationally connected with thebottom end of the upper housing, the diameter of one end of the screw rod is larger than that of the other end of the screw rod, the screw rod is in threaded connection with a fixed pedestal, the fixed pedestal is fixedly connected with a fixed mechanism configured to fix a rotor to be assembled, the fixed pedestal is internally provided with an inner diameter regulation mechanism, and the inner wall of the upper housing is fixedly connected with a drive stop module configured to drive the inner diameter regulation mechanism. The screw rod is moved to drive the rotor to move being gradually close to the stator so as to avoid the problem that generation of collision of the rotor and the stator or absorption of the rotor at the bottom portion of the stator under the magnetic adsorption effect of the magnetic steel at the surface of the rotor when the rotor is directly assembled to influence assembling.
Description
technical field [0001] The invention relates to the field of motor parts assembly, in particular to permanent magnet motor rotor assembly tooling. Background technique [0002] At present, with the rapid development of the automobile industry and the depletion of global oil resources, electric vehicles have become popular among the public in recent years. With its advantages and characteristics, permanent magnet motors have gradually become the drive system of electric vehicles, and have also developed rapidly in recent years. [0003] Permanent magnet motors are also called permanent magnet synchronous motors. Generally, permanent magnet structures (usually referred to as magnetic steel) are used on the rotor of the motor. Due to the existence of magnetic steel, there is a large magnetic pull between the rotor and the stator, which will make the rotor in assembly. During the process, the rotor and the stator collide with each other under the action of magnetic pull or are ...
