Detailed implementation manners

[0022] The following will further describe the present application in detail with reference to the Figures 1-5 accompanying drawings.

[0023] An embodiment of the present application discloses a spraying mechanism for metal parts. Refer to Figures 1-5 , a spraying mechanism for metal parts, including a spraying box 1 and a paint spraying tray 5 rotatably connected to the inner wall of the top of the spraying box 1 through a connecting seat 4. A plurality of spray heads 6 for spraying paint are arranged on the outer wall of the bottom of the paint spraying tray 5. An external gear ring 7 is fixedly connected to the outer wall of the paint spraying tray 5. A connecting pipe 8 is installed on the outer wall of the top of the spraying box 1. The connecting pipe 8 is communicated with the paint spraying tray 5. A shaft seat 9 is fixedly connected to the inner wall of the bottom of the spraying box 1. A turntable 10 is rotatably connected to the inner wall of the shaft seat 9. A gear disk 11 is fixedly connected to the outer wall of the top of the turntable 10. A guide rail frame 12 is fixedly connected to the outer wall of the top of the gear disk 11. Two relatively moving clamping blocks 13 are slidably connected to the outer wall of the top of the guide rail frame 12. A bracket 18 is fixedly connected to the outer wall of the guide rail frame 12. A placing table 19 is fixedly connected to the outer wall of the middle section of the top of the bracket 18. A clamping mechanism is installed on the outer wall of the guide rail frame 12. A driving assembly for driving the paint spraying tray 5 and the gear disk 11 to rotate in opposite directions is installed on the inner wall of the spraying box 1;

[0024] The driving assembly includes two connecting shafts 20 rotatably connected to the inner walls of the upper and lower sides of the spraying box 1. Driven gears 21 are fixedly connected to the outer walls of the two connecting shafts 20. The two driven gears 21 are respectively engaged with the gear disk 11 and the external gear ring 7. The opposite ends of the two connecting shafts 20 are fixedly connected with first bevel gears 22. A stepping motor 23 is fixedly installed on one inner wall of the spraying box 1. A second bevel gear 24 is fixedly connected to the output end of the stepping motor 23. The two first bevel gears 22 are symmetrically engaged with the second bevel gear 24.

[0025] The clamping mechanism includes a rotating shaft 14 rotatably connected to the inner wall of the middle section of the guide rail frame 12. A driving gear 15 is fixedly connected to the top end of the rotating shaft 14. Rack bars 16 are fixedly connected to the outer walls of the opposite sides of the two clamping blocks 13. The two rack bars 16 are both engaged with the driving gear 15.

[0026] A servo motor 17 is fixedly installed on the bottom outer wall of the turntable 10. The bottom end of the servo motor 17 passes through and extends out of the spraying box 1. The output shaft of the servo motor 17 penetrates the turntable 10 and the gear disk 11 and is fixedly connected to the bottom end of the rotating shaft 14.

[0027] A plurality of spray nozzles 6 are evenly distributed in a circumferential array at equal intervals on the bottom outer wall of the paint spraying disk 5, and the plurality of spray nozzles 6 are communicated with the paint spraying disk 5.

[0028] A box door 2 is hinged on the front outer wall of the spraying box 1. The box door 2 is closed to seal the inside of the spraying box 1, ensuring that the paint mist generated during painting will not disperse outside the spraying box 1 and pollute the environment.

[0029] A plurality of support legs 3 are fixedly connected to the bottom outer wall of the spraying box 1, and the plurality of support legs 3 are evenly distributed at the four corner edge positions of the spraying box 1.

[0030] The implementation principle of a metal part spraying mechanism according to an embodiment of the present application is as follows: during use, the box door 2 is opened, the metal part is placed on the placing table 19, and through the clamping mechanism, the servo motor 17 is started. The output shaft of the servo motor 17 drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the driving gear 15 to rotate. When the driving gear 15 rotates, it will drive the two racks 16 engaged with it to move relatively. As Figure 4 shown, when the two racks 16 move relatively, they drive the two clamping blocks 13 to slide relatively on the outer wall of the guide rail frame 12, thereby clamping and fixing the metal part placed on the placing table 19;

[0031] After the fixing is completed, the box door 2 is closed, the connecting pipe 8 is externally connected to external paint, and the external paint is conveyed into the paint spraying disk 5 through the connecting pipe 8 and atomized by the plurality of spray nozzles 6 and sprayed onto the surface of the metal part. At this time, through the driving assembly, the stepping motor 23 is started. The output shaft of the stepping motor 23 drives the second bevel gear 24 to rotate. As Figure 3 shown, since the two first bevel gears 22 are engaged with the second bevel gear 24 in an up-and-down opposite manner, the second bevel gear 24 drives the two first bevel gears 22 to rotate synchronously and reversely. The first bevel gear 22 drives the two driven gears 21 to rotate synchronously and reversely through the connecting shaft 20. At this time, the two driven gears 21 respectively drive the outer gear rings 7 and the gear disk 11 engaged with them to rotate in opposite directions. The gear disk 11 drives the placing table 19 to rotate through the guide rail frame 12 and the support 18. The placing table 19 drives the metal part to rotate, while the outer gear ring 7 drives the paint spraying disk 5 to rotate reversely inside the connecting seat 4, so that while the metal part is rotating and being painted, the plurality of spray nozzles 6 can rotate reversely around the metal part to spray paint, thereby effectively improving the uniformity of the paint spraying and ensuring the paint spraying quality;

[0032] It should be noted that after the spraying is completed, the surfaces of the outer wall of the metal part in contact with the two clamping blocks 13 are not sprayed. At this time, the clamping mechanism is used to drive the two clamping blocks 13 away from the outer wall of the metal part, and then the driving component is used to drive the part to rotate and the multiple nozzles 6 to rotate in the opposite direction for spraying, so that the outer wall of the part can be sprayed comprehensively.
