Description

Technical Field

[0001] The utility model relates to the field of engine nacelle cover processing, in particular to a spraying device for a special-shaped surface of an engine nacelle cover. Background Art

[0002] The nacelle cover is a component of wind power generation equipment. After the nacelle cover is processed, it is necessary to spray a logo on its surface. The logo is mainly located on its side. Since there are some curved parts on the side of the nacelle cover and the volume of the nacelle cover is large, it is more complicated to locate the spraying position of the nacelle cover.

[0003] Based on the above problems, the present invention designs a spraying device for the special-shaped surface of a cabin cover, which scans the outer surface of the sprayed logo, and can scan some characteristic parts that are convenient for positioning during the scanning process, and then form them in a computer, and then project a one-to-one logo onto the scanned and formed surface to generate a laser engraving route. Then, the logo position needs to be covered with adhesive tape for protection, and then engraving is performed. After the engraving is completed, the adhesive tape of the sprayed logo inside the engraving line is torn off, the sprayed area is polished, and finally, the logo is sprayed. In the above process, the scanning and imaging process of a larger cabin cover is relatively complicated and inefficient, which will affect the spraying efficiency. Based on this, the present invention designs a spraying device for the special-shaped surface of a cabin cover. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figure 1-4 As shown, a nacelle cover profiled surface spraying device comprises:

[0025] A spray box 1 is provided with a spray assembly in the spray box 1. The spray assembly can use a conventional spray pipe in the prior art. A box door 2 is provided and connected to one side of the spray box 1. A paint box 9 is connected to the top of the spray box 1. A feed pipe 10 is connected to the top of the paint box 9. The paint box 9 is connected to the spray assembly for replenishing paint.

[0026] A base plate 3, on which the spray box 1 is mounted, and in which a transport assembly 5 for transporting the nacelle cover 4 is arranged;

[0027] The scanning component 6 scans and images the nacelle 4 entering the spray box 1 so as to determine the curved surface contour of the nacelle 4. The scanning component 6 is connected to a swing component 7 which enables the scanning component 6 to swing in a vertical plane.

[0028] The transport component 5 includes several groups of pressure blocks 51, each group of two, and there are no less than two groups of pressure blocks 51. The several groups of pressure blocks 51 are matched and arranged at the bottom of the cabin cover 4. Each group of pressure blocks 51 is commonly connected to a conveyor belt 52 opened in a groove 8 in the bottom plate 3. The conveyor belt 52 adopts a steel belt structure and is respectively connected to conveying wheels 53 on both sides. One conveying wheel 53 is connected to a driving motor. The scanning component 6 includes a fixed cylinder 61 fixedly connected to the bottom plate 3. The top of the fixed cylinder 61 is connected to a mounting platform 62, and a scanning source 63 is arranged in the mounting platform 62.

[0029] The swing assembly 7 includes a toothed belt 71 arranged in the two conveyor belts 52, and the toothed belt 71 is located on the side of the conveyor belt 52 away from the groove 8. In this way, when the conveyor belt 52 drives the nacelle 4 to move, the rack will drive the meshing gear 72 to rotate, and the rotation center of the gear 72 is connected to a transmission shaft 73, the transmission shaft 73 is coaxially arranged with the fixed cylinder 61, and the fixed cylinder 61 is sleeved on the outside of the transmission shaft 73, the upper side part of the transmission shaft 73 passes through the mounting platform 62 and is connected to an incomplete bevel gear 74 on one side of the mounting platform 62, the number of teeth of the incomplete bevel gear 74 is half of the number of teeth of the complete bevel gear 74, and the incomplete bevel gear 74 is connected to the incomplete bevel gear 74. A transmission bevel gear 75 is meshed on both sides of the gear 74. Therefore, during the process of the complete bevel gear 74 rotating one circle, one transmission bevel gear 75 will be driven to rotate in each half cycle. In this way, during a complete rotation cycle, the rotating shaft 76 and the adjustment frame 77 connected by the two transmission bevel gears 75 drive the adjustment frame 77 to swing. The scanning source 63 is installed on the adjustment frame 77. The two end faces of the rotating shaft 76 are rotatably connected to the two side walls of the mounting platform 62. The scanning angle of the scanning source 63 is adjusted by the adjusting frame 77 and the rotating shaft 76 to improve the scanning effect of the scanning source 63 on the cabin cover 4.

[0030] When the present invention is in use, the cabin cover 4 is first placed in a plurality of pressure blocks 51 through the lifting structure to realize the positioning of the cabin cover 4, and then the cabin cover 4 is driven to move toward the spray box 1 through the conveyor belt 52 and the conveyor wheel 53 in the transport component. During the above movement, the toothed belt 71 located on the conveyor belt 52 simultaneously drives the gear 72 to rotate, so that the scanning source 63 in the scanning component 6 is in a swinging working state, which can better realize the scanning imaging function of the cabin cover 4, until the cabin cover 4 completely enters the spray box 1, the scanning work is completed, and the information obtained by the scanning component 6 is used to complete the adhesive tape coating work and laser engraving work on the outside of the cabin cover 4, so as to obtain a complete spraying area, and spraying is carried out through the spraying component. Finally, after the spraying work is completed, the cabin cover 4 is output through the transport component 5 and leaves the spray box 1. When the cabin cover 4 leaves, it will also drive the scanning component 6 to swing, so that the sprayed product can be inspected.
