Surface dust-free coating production line for auto parts

Abstract

The invention relates to a surface dust-free coating production line for auto parts. The surface dust-free coating production line for auto parts comprises a portal frame, a driving electric slide block, an inner diameter clamp, an externally connected ring, connecting frames and equally spaced spray heads. The driving electric slide block is mounted at the upper end of the portal frame, the externally connected ring is mounted at the lower end of the driving electric slide block, the lower end of the externally connected ring is connected to the portal frame in a sliding fit manner, the connecting frames are uniformly arranged on the inner wall of the externally connected ring along the circumferential direction, the equally spaced spray heads are uniformly arranged on the inner end surface of each connecting frame, the inner diameter clamp is mounted at the left end of the portal frame, and the inner diameter clamp is located in the externally connected ring. The surface dust-free coating production line can solve the problems that the thicknesses of coating liquids in parts of an exhaust tube are different as the coating distances from existing spray heads to the parts of the exhaust tube are different as the bore diameters of the parts of the exhaust tube are different, and the existing spray heads are likely to spray the coating liquids to the inner wall of the exhaust tube as the orifice of part of the exhaust tube is of an inclined structure and the like.

Description

technical field [0001] The invention relates to the field of coating of auto parts, in particular to a dust-free coating production line for the surface of auto parts. Background technique [0002] Auto parts are the units that constitute the overall processing of auto parts and the products that serve the processing of auto parts. Among them, the exhaust pipe is a kind of auto parts, and the surface of the exhaust pipe needs to be coated to prevent rust. During the painting operation, the existing spray head usually sprays the rotating exhaust pipe, but the following problems are often encountered in the painting operation: [0003] 1. Due to the different apertures of the various parts of the exhaust pipe, the spraying distances of the existing nozzles to the various parts of the exhaust pipe are different, which makes the spraying range of the existing nozzles different, resulting in different thicknesses of the coating liquid for each part of the exhaust pipe, and the co...

AI Technical Summary

Problems solved by technology

[0006] The present invention can solve the problem of different spraying distances between the existing nozzles and different parts of the exhaust pipe due to the different apertures of the various parts of the exhaust pipe during the existing painting operation, resulting in different spraying ranges of the existing nozzles, resulting in various parts of the exhaust pipe. The thickness of the coating liquid is different, and it may cause an over-spray situation during painting. Since the nozzle of some exhaust pipes is an inclined structure, when spraying the nozzle, the existing nozzle is easy to spray the coating liquid to the exhaust pipe. problems on the inner wall of the
