DETAILED DESCRIPTION

[0018] The following are examples and the attached Figure 1-2 , the technical solution of the present invention is further specifically described.

[0019] An automatic spraying device for wheel hub production, comprising a machine platform 1, wherein a paint spraying box 2 is arranged on the top of the machine platform 1, a circle of surrounding edges 3 is arranged on the top of the machine platform 1 in the paint spraying box 2, wherein a drying mechanism I4 is arranged in the surrounding edges 3, and a drying mechanism II5 is arranged on the inner wall of the paint spraying box 2 above the surrounding edges 3, and a paint spraying mechanism 6 is also arranged on the top of the paint spraying box 2 and located directly above the surrounding edges 3;

[0020] The drying mechanism 14 comprises an infrared paint-baking lamp 141 suspended above the surrounding edge 3, wherein a lampshade 42 driven by an electric push rod 43 is buckled on the infrared paint-baking lamp 141;

[0021] The drying mechanism II5 includes a circle of rectangular frame 51, wherein an infrared paint lamp II52 is arranged on the inner wall of the paint spray box 2 outside the rectangular frame 51, and a convex block 53 is arranged on the outer wall of the rectangular frame 51, and a screw rod 54 connected to a motor 55 is arranged on the convex block 53;

[0022] The paint spraying mechanism 6 includes a mounting plate 61 driven by a hydraulic rod 62, wherein two circles of paint spraying tubes 63 are coaxially arranged below the mounting plate 61, and the paint spraying tubes 63 are connected to the mounting plate 61 through vertical rods 64, and multiple groups of spray heads 65 are arranged at the bottom of the paint spraying tubes 63, wherein the spray heads 65 are inclined toward the position directly below between the two groups of paint spraying tubes 63.

[0023] like Figure 1 As shown, liquid outlet pipes 7 are provided on the workbench 1 inside and outside the surrounding edge 3 , wherein the liquid outlet pipes 7 are connected to a liquid collecting box 8 inside the workbench 1 .

[0024] In this embodiment, a liquid storage tank 9 is arranged above the paint spraying box 2, wherein the liquid storage tank 9 is connected to the paint spraying pipe 63 through a hose.

[0025] In this embodiment, a mounting seat 10 for fixing both ends of the screw rod 54 is arranged on the inner wall of the paint spray box 2, wherein a rolling bearing which is sleeved on the screw rod 54 is arranged on the mounting seat 10, and a screw hole which is screwed to the screw rod 54 is opened on the protrusion 53.

[0026] like Figure 1 As shown, the infrared paint baking lamp II52 is located on the inner wall of the paint spray box 2 between the upper and lower ends of the rectangular frame 51.

[0027] In this embodiment, the lampshade 42 is located directly below the opening of the inner circle paint spraying tube 63, wherein a base 11 for fixing the infrared paint baking lamp I41 is provided on the workbench 1, and the bottom end of the lampshade 42 is located on the top surface of the base 11.

[0028] like Figure 1 As shown: when in use, the wheel hub is placed on the top of the surrounding edge 3, and the surrounding edge 3 is abutted against the side wall of the wheel hub edge to fix it in the air, and then the hydraulic rod 62 drives the mounting plate 61 and the vertical rod 64 to drive the two sets of paint spraying pipes 63 to move downward, so that the two sets of paint spraying pipes 63 move up and down on the outside of the wheel hub and the inside of the opening. At this time, the paint liquid in the liquid storage tank 9 is injected into the paint spraying pipes 63 through the pump and the hose, and is sprayed out by a plurality of nozzles 65, so that the paint spraying work on the inner and outer walls of the wheel hub is realized simultaneously through the paint spraying pipes 63 and the nozzles 65 that move up and down;
