Flexible automatic assembling mechanism and method for automobile driving motor

Abstract

The invention discloses a flexible automatic assembling mechanism and method for an automobile driving motor. The assembling mechanism comprises a stator positioning tool used for placing a stator assembly, a rotor positioning tool used for placing a rotor assembly, a tool moving mechanism used for moving the stator positioning tool and the rotor positioning tool to an assembling station, and an assembling motor mechanism. The assembling motor mechanism comprises a pressing plate, a stator moving mechanism used for driving the pressing plate to reciprocate in the axial direction of an assembling motor and a guide rod, the pressing plate is arranged at the top of the assembling station, a stator clamping mechanism used for clamping and fixing a stator assembling part is arranged on the bottom face of the pressing plate, and the guide rod penetrates through the pressing plate in a sliding mode and can stretch out and draw back to adjust the length. When the stator and the rotor are assembled, the guide rod is extended to be coaxially fixed with the rotating shaft of the rotor assembly, so that the rotating shaft is kept not to shake, movement of the pressing plate and the stator assembly can be guided, adsorption scraping in the stator and rotor assembling process is effectively avoided, and the assembling quality is improved.

Description

technical field [0001] The invention relates to the technical field of motor assembly, in particular to a flexible automatic assembly mechanism and method for an automobile drive motor. Background technique [0002] At present, the single-motor stator and rotor assembly method is as follows: first, the rear end cover rotary chamber in the stator and end cover assembly is used as the center positioning, and then it is axially fixed, and then the rotor is clamped by three claws and the top form. The stator and rotor are assembled by moving the rotor up and down. This assembly method can only be fixed at one end of the rotor shaft. Because the permanent magnet of the stator has strong magnetism, it will cause the stator and rotor to absorb and scratch, and the rotor shaft head bears the leverage force, which cannot be achieved. Guarantee the quality of motor assembly. [0003] In addition, the current mainstream two-in-one drive motor is usually combined with the rotor and the...

[0002] At present, the single-motor stator and rotor assembly method is as follows: first, the rear end cover rotary chamber in the stator and end cover assembly is used as the center positioning, and then it is axially fixed, and then the rotor is clamped by three claws and the top form. The stator and rotor are assembled by moving the rotor up and down. This assembly method can only be fixed at one end of the rotor shaft. Because the permanent magnet of the stator has strong magnetism, it will cause the stator and rotor to absorb and scratch, and the rotor shaft head bears the leverage force, which cannot be achieved. Guarantee the quality of motor assembly

[0003] In addition, the current mainstream two-in-one drive motor is usually combined with the rotor and the reducer, using the suspension hole of the reducer for profiling positioning and axial support, and designing a positioning hole and a clamping boss on the outer circle of the stator assembly. The mechanism clamps the outer circle of the stator assembly, drives the stator assembly to move up and down, and realizes the combination of the stator and the rotor. During the assembly process of this type of assembly, the rotating shaft of the rotor assembly is not fixed, and there is also the risk of the stator and rotor attracting and scratching each other. , and the outer circle of the stator assembly must have a clamping and positioning boss, the assembly quality cannot be guaranteed and the flexibility of the equipment is low
