[0032] The positioning mechanism includes a support seat 13, a telescopic assembly, three slide grooves 14, three sliders 15 and three positioning plates 16. The support seat 13 is fixedly mounted on the top of the turntable 12. The three slide grooves 14 are equidistantly arranged on the surface of the support seat 13. Each slider 15 is slidably arranged inside a slide groove 14. Each positioning plate 16 is fixedly mounted on the top of a slider 15. The telescopic assembly is located between the support seat 13 and the three sliders 15.

[0033] The telescopic assembly can drive the three sliders 15 to slide inside the three slide grooves 14, and then drive the positioning plate 16 to move, and adjust the position of the positioning plate 16 so that the three positioning plates 16 can contact the inner wall of the wheel hub and tightly fix the wheel hub, ensuring that the wheel hub can be stably placed for easy spraying;

[0034] The spraying mechanism includes a spray head 27, a swing assembly and a transmission assembly. A mounting frame 25 is fixedly mounted on the top of the workbench 11, a rotating rod 26 is rotatably arranged on the mounting frame 25, the spray head 27 is fixedly mounted on one end of the rotating rod 26, the swing assembly is located at the end of the rotating rod 26 away from the spray head 27, and the transmission assembly is located between the swing assembly and the driving assembly;

[0035] The swing assembly can drive the spray head 27 to swing, and combined with the driving assembly, the paint can be sprayed on the surface of the wheel hub, so as to achieve uniform spraying on the surface of the wheel hub and avoid dead angles of spraying.

[0036] like Figure 1-Figure 6 As shown, the driving assembly includes a second motor 22, a second spur gear 21 and a first spur gear 20, the second spur gear 21 and the turntable 12 are coaxially arranged, the second spur gear 21 is located below the workbench 11, the first spur gear 20 is rotatably arranged at the bottom end of the workbench 11, the first spur gear 20 and the second spur gear 21 are meshed, the second motor 22 is fixedly installed on the top of the workbench 11, and the output end of the second motor 22 is fixedly connected to the first spur gear 20;

[0037] When the wheel hub needs to be rotated, the wheel hub is first positioned at the top of the support seat 13, and then the second motor 22 is controlled to work. The second motor 22 can drive the first spur gear 20 to rotate. Since the first spur gear 20 and the second spur gear 21 are meshed, when the first spur gear 20 rotates, it can drive the second spur gear 21 to rotate, and then drive the turntable 12 to rotate, so that the wheel hub located above the support seat 13 can be rotated, which is convenient for spraying different positions of the wheel hub.

[0038] like Figure 1-Figure 6 As shown, the swing assembly includes a swing rod 29, an insertion rod 31, a strip groove 30 and a rotating rod 32. A vertical plate 36 is fixedly installed on the top of the workbench 11. One end of the rotating rod 26 away from the nozzle 27 is rotatably set on the vertical plate 36. The swing rod 29 is fixedly installed at the end of the rotating rod 26. The strip groove 30 is opened on the surface of the swing rod 29. One end of the insertion rod 31 is inserted into the inside of the strip groove 30. The other end of the insertion rod 31 is fixedly connected to one end of the rotating rod 32. The other end of the rotating rod 32 is rotatably set on the vertical plate 36.

[0039] When the driving assembly is working, the transmission assembly can drive the rotating rod 32 to rotate, and when the rotating rod 32 rotates, it can drive the insertion rod 31 to rotate. Since the insertion rod 31 is inserted into the inside of the strip groove 30, when the rotating rod 32 rotates, it can drive the swing rod 29 to swing around the axis of the rotating rod 26. When the rotating rod 26 swings, it can drive the spray head 27 to swing. Combined with the driving assembly, the paint can be sprayed on the surface of the wheel hub, so as to achieve uniform spraying on the surface of the wheel hub and avoid dead angles in spraying.

[0040] like Figure 1-Figure 6 As shown, the transmission assembly includes a driving wheel 33, a driven wheel 34, a transmission belt 35, a first bevel gear 23 and a second bevel gear 24, the first bevel gear 23 and the second spur gear 21 are coaxially arranged, the second bevel gear 24 is rotatably arranged at the bottom end of the workbench 11, the first bevel gear 23 and the second bevel gear 24 are meshed, the driving wheel 33 is located on one side of the second bevel gear 24 and is coaxially arranged with the second bevel gear 24, the driven wheel 34 is coaxially arranged with the end of the rotating rod 32, and the transmission belt 35 is sleeved on the driving wheel 33 and the driven wheel 34;

[0041] When the second spur gear 21 rotates, it can drive the first bevel gear 23 to rotate. Since the first bevel gear 23 and the second bevel gear 24 are meshed with each other, when the first bevel gear 23 rotates, it can drive the second bevel gear 24 to rotate. When the second bevel gear 24 rotates, it can drive the driving wheel 33 to rotate synchronously. Under the action of the transmission belt 35, it can drive the driven wheel 34 to rotate, thereby realizing the operation of the swing assembly.

[0042] By setting up a transmission component, the turntable 12 can drive the wheel hub to rotate while driving the nozzle 27 to swing continuously, thereby achieving a linkage effect between the rotating mechanism and the spraying mechanism, which is beneficial to reducing the number of driving sources used in this equipment, reducing power consumption, and thus helping to reduce costs.

[0043] like Figure 1-Figure 6 As shown, the telescopic assembly includes a first motor 19, a disc 18 and three hinged rods 17. The disc 18 is rotatably arranged at the bottom end of the support seat 13. The first motor 19 is installed at the top end of the rotating disk 12. The output end of the first motor 19 is fixedly connected to the disc 18. The bottom end of each slider 15 is hinged to one end of a hinged rod 17, and the other end of each hinged rod 17 is hinged to the surface of the support seat 13.

[0044] When the wheel hub needs to be fixed, the first motor 19 is controlled to work, and the first motor 19 can drive the disc 18 to rotate. When the disc 18 rotates, it can drive the slider 15 to slide inside the slide groove 14 under the action of the hinge rod 17, and then drive the positioning plate 16 to move, so that the three positioning plates 16 can contact the inner wall of the wheel hub and fix the wheel hub tightly, ensuring that the wheel hub can be stably placed to facilitate the spraying work.

[0045] like Figure 1-Figure 6 As shown, the top end of the nozzle 27 is connected to a hose 28, and the other end of the hose 28 is connected to a conveying device for conveying paint. The conveying device can convey the paint to the nozzle 27, and the nozzle 27 is used to spray the paint on the surface of the wheel hub. At the same time, the setting of the hose 28 is conducive to the swinging operation of the nozzle 27.
