The spray assembly 8 is connected to the hydraulic control box 7 and the paint box 4 and sprays the sheet metal part 1. The spraying assembly 8 includes a connecting plate 81, a balancing frame 83, a material dividing assembly 84, a detector 85, a hydraulic pressure device 86 and an adjustment assembly 87. The upper end of the connecting plate 81 is fixedly connected to the adapter plate 6, and the lower end of the connecting plate 81 is connected to the balancing frame 83 via a through shaft. A plurality of material dividing assemblies 84 are evenly distributed on the lower end of the balancing frame 83, each of the material dividing assemblies 84 is connected to the balancing frame 83 via a hydraulic pressure device 86, and each of the material dividing assemblies 84 is correspondingly installed with an adjustment assembly 87, and the detector 85 is placed below the material dividing assembly 84 in the middle.

[0016] It should be explained that the surface of the sheet metal part 1 is usually curved with arcs and grooves, with bends at different joints and different curvatures on different surfaces. It is usually necessary to form a uniform coverage surface through reciprocating spraying. However, the thickness of the track surface after single spraying or reciprocating spraying is difficult to control during the whole process, and the surface quality of the finished product cannot be guaranteed. The present invention performs spraying by cooperating with a spray assembly 8 and mechanical arm assemblies such as a turntable 21, an adjusting arm 3, an extension shaft 5 and an adapter plate 6. The paint box 4 supplies paint to the spray assembly 8. The spray assembly 8 adjusts and controls different material distribution assemblies 84 to work independently to adjust the thickness and uniformity of a single spraying. The transmission path composed of a hydraulic control box 7, a hydraulic machine 86 and an adjusting assembly 87 adjusts the material distribution assembly 84 to control the spraying angle to ensure the vertical relationship between the spraying direction and the spraying surface on the spraying path. In addition, the spray thickness during the spraying process is detected by a detector 85.

[0017] As a preferred embodiment, the spraying assembly 8 further includes a transmission tube bundle 88 and a positioning pin 82, wherein the transmission tube bundle 88 is used to connect the paint box 4 and the material distribution assembly 84, and the positioning pin 82 is used to calibrate the connection between the connecting plate 81 and the adapter plate 6.

[0018] As a preferred embodiment, a plurality of supply pumps are provided in the paint box 4 , which are independently connected to supply different material distribution components 84 .

Taking the two spray discs 843 in a single material distribution assembly 84 as an example, when it is necessary to increase the thickness of a single spray, the spray disc 843 can be deflected and adjusted to form an inclined angle relative to the outlet, so that the spray coverage of the spray disc 843 overlaps; When the single spraying width needs to be increased, the spraying disc 843 can be deflected and adjusted to form an angle where the outlets are tilted opposite to each other, so that the spraying coverage of the spraying disc 843 is spliced ​​to increase the coverage range.
