Spraying tooling of motor vehicle wheel hub

Spraying tooling of a motor vehicle wheel hub, the spraying tooling comprising an assembly line, a plurality of wheel hub bases each capable of moving on the assembly line, a plurality of driving mechanisms each capable of driving one of the plurality of wheel hub bases to rotate at a preset position on the assembly line, a plurality of triggering components each capable of triggering one of the plurality of driving mechanisms to operate, a plurality of maintaining components each capable of maintaining a preset time for one of the plurality of triggering components, and a controller;

• wherein each of the plurality of wheel hub bases comprises a sliding seat capable of moving on the assembly line and a tray capable of rotating along with rotation of a respective one of the plurality of driving mechanisms, and the tray is rotatably mounted on the sliding seat;
• and each of the plurality of driving mechanisms and each of the plurality of triggering components are electrically connected to the controller,
• wherein a bottom of the tray comprises a rotating shaft, an end of the rotating shaft is fixed to the bottom of the tray, another end of the rotating shaft is rotatably mounted to the sliding seat, and the sliding seat comprises a rolling bearing matched with the rotating shaft;
• and the tray is rotatably mounted to the sliding seat through the rotating shaft;
• the assembly line comprises a guide rail, a conveying belt and a first motor, the guide rail is fixed to ground, and the conveying belt moves relative to the guide rail under driving of the first motor;
• and the sliding seat moves on a surface of the guide rail under driving of the conveying belt;
• each of the plurality of driving mechanisms comprises a second motor fixed to a side of the guide rail and a first gear mounted to an output shaft of the second motor, a second gear matched with the first gear is arranged on the rotating shaft in a sleeve manner, and the second gear is fixed to the rotating shaft;
• and the second motor operates when a respective one of the plurality of triggering components is triggered;
• and
