The distance between the motor housings 4 is always kept relatively stable, and the time and amount of paint mist received by each part of the motor housing 4 during the painting process are more uniform, so that the coating thickness on the surface of the motor housing 4 is uniform, effectively avoiding problems such as too thick or too thin paint layer, sagging, color spots, etc. caused by distance changes or unstable rotation speed, thereby improving the quality and aesthetics of the painting; the paint mist can be sprayed on the motor housing 4 more accurately, reducing the diffusion and splashing of the paint mist in the air, improving the utilization rate of the paint, reducing material costs, and reducing pollution to the working environment; a group of reducers 57 simultaneously controls the movement of two components, which is convenient for realizing the automation of the entire painting process, and there is no need to manually operate the lifting and lowering of the paint spray gun 69 and the rotation of the motor housing 4. , reducing manual intervention, reducing labor intensity, and improving production efficiency; the driving part can accurately adjust the lifting speed of the paint spray gun 69 and the rotation speed of the motor housing 4 according to the shape, size and painting process requirements of the motor housing 4, so that the two can achieve the best matching state, and on the premise of ensuring the quality of painting, the painting time of a single motor housing 4 can be shortened to the maximum extent, thereby improving production efficiency; a set of driving parts is used to realize the movement of the motor housing 4 and the paint spray gun 69, which reduces the number of parts of the equipment, simplifies the overall structure of the equipment, and reduces the manufacturing and procurement costs of the equipment compared to using two sets of independent driving systems; the simplification of the equipment structure means that fewer parts need to be maintained and maintained, reducing the complexity and workload of maintenance work;At the same time, due to the reduction in the number of driving parts, the probability of failure is relatively reduced.
