Thereafter, the PLC issues a command to slide the lift cylinder mounting base plate 22 along the second slide 42 (i.e., in the X-axis direction) to a slide end near the second tip 44, thereby making room for the rotor to enter the multi-piece assembly. The rotor is fed into the assembling device manually by a worker or by a robot, namely, the center of the rotor is aligned with the first center 43 for positioning and clamping, the PLC then controls the second sliding table 42 to move along the first sliding table 41 to enable the second center 44 to be close to the first center 43 to realize stable clamping on the rotor (the hand of the worker or the robot can leave the rotor after stable clamping), then the PLC controls the lifting cylinder mounting base plate 22 to slide along the second sliding table 42 towards the direction close to the first center 43 to complete assembling of the stator and the rotor (the sliding distance of the lifting cylinder mounting base plate on the second sliding table is calculated by the PLC), of course, in the assembling process of the stator and the rotor, the pressure sensor 5 can monitor the pressure change in the assembling process in real time, the lifting cylinder 21 can make adaptive adjustment on the height of the center of the stator according to the pressure signal provided by the pressure sensor 5 under the control of the PLC, to ensure the smooth assembly process. After the stator and the rotor are assembled together, the PLC controls the second sliding table 42 to slide along the first sliding table 41 in the direction away from the first center 43, so that the assembled motor is separated from the clamping limitation of the first center 43, then the PLC controls the lifting cylinder mounting base plate 22 to slide along the second sliding table 42 in the direction away from the second center 44, the sliding distance is not large, only the rotor is separated from the clamping limitation of the second center 44, then the PLC controls the lifting cylinder 21 to reset to enable the working platform 23 to descend to the original horizontal conveying height, and finally the motor and the tooling plate 11 are removed from the working platform manually by a worker or by a robot, so that the whole assembling process of the motor stator and the rotor is completed.
This equipment automatic control nature that attaches together is strong, can carry out the line operation with the equipment transfer chain of motor, consider that this equipment that attaches together needs the stator that adapts to different styles or model motors to attach together, consequently this attach together equipment setting attach together highly generally higher, the actuating mechanism that Z moved is done as the stator to the high module that lifts of stator, then just in time with motor equipment transfer chain height when its work platform is in not by the lifting state to accept the frock board smoothly and get into the equipment that attaches together.
This attach together equipment has the function of flexible closed-loop control and gentle and agreeable assembly concurrently, through putting fixedly rotor central point, attach together the model of motor as required, the center of equipment automatic adjustment stator to coaxial with the rotor, reach the self-adaptation purpose that the motor of different models and style attached together (attaching together of compatible many money city rail/mark motor), the signal feedback that combines pressure sensor simultaneously in time makes the adjustment to work platform's height, make attaching together of stator and rotor go on accurately smoothly, effectively improve motor assembly quality.
