[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Reference Figures 1-4The painting machine shown is suitable for use with rims of different sizes. It includes a worktable 1, a placement tray 17 mounted on the top of the worktable 1 via a rotating mechanism, an mounting plate 5 mounted on the top of the worktable 1 via a telescopic mechanism, a U-shaped plate 13 mounted on the side of the mounting plate 5 via a moving mechanism, an upper spray head 7 mounted on the U-shaped plate 13 via an adjusting mechanism, a threaded moving mechanism mounted on the U-shaped plate 13, and two side spray heads 18 mounted on the threaded moving mechanism. The upper spray head 7 is located between the two side spray heads 18, and the upper spray head 7 and the two side spray heads 18 are all positioned corresponding to the placement tray 17. The upper spray head 7 and the two side spray heads 18 in this application can be connected to a paint supply pump via a hose, and the paint supply pump is connected to a paint storage tank. The paint is delivered by the paint supply pump. This application does not have a sliding mechanism, which is prior art and will not be described in detail here.
[0022] With the above structure: In use, the wheel hub is placed at the top center of the placement plate 17. Depending on the size of the wheel hub, the position of the upper spray head 7 is adjusted by the adjustment mechanism, and the distance between the two side spray heads 18 is adjusted by the threaded moving mechanism, so as to meet the needs of wheel hubs of different sizes. Finally, the two side spray heads 18 and the upper spray head 7 are aligned with the wheel hub by the adjustment mechanism and the telescopic mechanism. By starting the rotation mechanism, the placement plate 17 can be rotated, thereby making the wheel hub rotate to achieve painting.
[0023] like Figure 3 As shown, the rotating mechanism includes a motor 15 fixedly mounted on the bottom of the worktable 1. A rotating shaft 16 is fixedly mounted on the output shaft of the motor 15. The top end of the rotating shaft 16 passes through the top of the worktable 1 and is fixedly connected to the center of the bottom of the placement tray 17. By starting the motor 15, the rotating shaft 16 can be rotated, and the rotation of the rotating shaft 16 causes the hub to rotate.
[0024] like Figure 1 and Figure 2 As shown, the telescopic mechanism includes two movable shafts 3 fixedly mounted on the top of the workbench 1. Movable plates 4 are slidably sleeved on the two movable shafts 3. The bottom of a mounting plate 5 is fixedly mounted on the top of the movable plates 4. A telescopic hydraulic cylinder 2 is fixedly mounted on the top of the workbench 1, and the movable end of the telescopic hydraulic cylinder 2 is fixedly connected to the bottom of the movable plates 4. Activating the telescopic hydraulic cylinder 2 causes the two side nozzles 18 and the upper nozzle 7 to descend, thus aligning with the inner and outer rings and the top of the hub.
[0025] like Figure 2 and Figure 4As shown, the moving mechanism includes a threaded sleeve 12 fixedly installed on the side of the U-shaped plate 13. A rotating hole is provided on the side of the mounting plate 5, and a first rotating rod 9 is rotatably installed within the rotating hole. Both ends of the first rotating rod 9 extend outside the rotating hole. A first external thread 8 is provided on the first rotating rod 9, and the first external thread 8 is threaded into the threaded sleeve 12. A first knob 10 is fixedly installed at the end of the first rotating rod 9 away from the threaded sleeve 12. A guide rod 24 is fixedly installed on the side of the U-shaped plate 13, and a guide hole is provided on the side of the mounting plate 5. The guide rod 24 is slidably installed within the guide hole. Rotating the first knob 10 causes the first rotating rod 9 to rotate. The rotation of the first rotating rod 9 drives the threaded sleeve 12 to move via the first external thread 8. The movement of the threaded sleeve 12 drives the U-shaped plate 13 to move, thereby aligning the two side nozzles 18 and the upper nozzle 7 with the hub.
[0026] like Figure 2 and Figure 4 As shown, the threaded moving mechanism includes a movable hole opened on the inner wall of the U-shaped plate 13 away from the guide rod 24. A second rotating rod 21 is rotatably installed in the movable hole. Both ends of the second rotating rod 21 extend outside the movable hole. One end of the second rotating rod 21 is rotatably installed on the inner wall of the U-shaped plate 13, and the other end of the second rotating rod 21 is fixedly installed with a second knob 20. Two oppositely arranged second external threads 22 are opened on the second rotating rod 21. Z-shaped plates 19 are threadedly sleeved on the two second external threads 22. The bottom ends of the two Z-shaped plates 19 are respectively fixedly installed on the top of the two side nozzles 18. Positioning rods 23 are fixedly installed on the inner walls of both sides of the U-shaped plate 13. The two Z-shaped plates 19 are slidably sleeved on the positioning rods 23. By rotating the second knob 20, the second rotating rod 21 is driven to rotate. The rotation of the second rotating rod 21 drives the two Z-shaped plates 19 to move away from each other through the two second external threads 22, thereby adjusting the position of the two side nozzles 18 so that the distance between the two side nozzles 18 is equal to the distance between the outer ring and the inner ring of the hub.
[0027] like Figure 2 As shown, the adjustment mechanism includes two adjustment holes on the inner wall of the top side of the U-shaped plate 13. A sliding frame 14 is slidably installed in both adjustment holes. The upper spray head 7 is fixedly installed on the bottom of the sliding frame 14. Threaded holes are provided on the inner walls of the two adjustment holes, and bolts 6 are threaded into each threaded hole. The ends of the two bolts 6 that are close to each other abut against the two sides of the sliding frame 14. Loosening the two bolts 6 and then moving the sliding frame 14 adjusts the position of the upper spray head 7. After adjusting to the appropriate position, tightening the two bolts 6 fixes the position of the upper spray head 7, thus accommodating the painting of wheel hubs of different thicknesses.
[0028] like Figure 2 and Figure 4As shown, both the second rotating rod 21 and the first rotating rod 9 are provided with a third external thread, and a nut 11 is threaded onto each of the two third external threads. The sides of the two nuts 11 abut against the sides of the mounting plate 5 and the U-shaped plate 13, respectively. The two nuts 11 can be used to fix the second rotating rod 21 and the first rotating rod 9 when they stop rotating.
[0029] Working principle:
[0030] When in use, place the hub at the top center of the placement plate 17. During placement, an alignment device can be used for calibration. The alignment device can be two telescopic cylinders and two arc plates. The moving ends of the two telescopic cylinders are connected to the arc plates, so that the hub can be positioned in the middle. During installation, the two telescopic cylinders are set perpendicular to the U-shaped plate 13 to achieve alignment. Then, depending on the size of the hub, first turn a nut 11 to separate it from the side of the U-shaped plate 13. Then, turn the second knob 20 to drive the second rotating rod 21 to rotate. The rotation of the second rotating rod 21 drives the two Z-shaped plates 19 to move away from each other through the two second external threads 22, thereby adjusting the position of the two side nozzles 18 so that the distance between the two side nozzles 18 is equal to the distance between the outer and inner rings of the hub. Then, turn the nut 11 in the opposite direction to fix the position of the second rotating rod 21.
[0031] Continue to loosen the two bolts 6, and then move the sliding frame 14 to adjust the position of the upper nozzle 7. After adjusting to the appropriate position, tighten the two bolts 6 to fix the position of the upper nozzle 7. Then rotate the other nut 11 to separate it from the side of the mounting plate 5. By rotating the first knob 10, the first rotating rod 9 can be rotated. The rotation of the first rotating rod 9 drives the threaded sleeve 12 to move through the first external thread 8. The movement of the threaded sleeve 12 drives the U-shaped plate 13 to move, so that the two side nozzles 18 and the upper nozzle 7 correspond to the hub.
[0032] Finally, the telescopic hydraulic cylinder 2 is activated, causing the two side nozzles 18 and the upper nozzle 7 to descend and align with the inner and outer rings and the top of the wheel hub. By starting the motor 15, the rotating shaft 16 can be rotated, which in turn causes the wheel hub to rotate, thus enabling the painting process.
[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
