Description

Technical Field

[0001] This utility model relates to the field of motor housing processing technology, and in particular to a painting device for processing motor housings. Background Technology

[0002] In the field of motor manufacturing, it is often necessary to paint the motor housing to effectively enhance the overall corrosion resistance of the motor, which requires the use of appropriate painting equipment.

[0003] In the painting of motor housings, traditional fixed spray guns struggle to adapt to the complex heat dissipation fin structure on the housing surface, easily creating spray dead zones in the gaps between the fins, resulting in uneven paint film. Simultaneously, open-air spraying operations cause severe paint mist diffusion, polluting the working environment and endangering the health of operators. While existing equipment attempts to improve coverage through multi-angle nozzle layouts, it still lacks an effective dynamic spraying mechanism for the narrow areas between the fins, easily leading to incomplete painting of the motor housing. Therefore, we propose a painting device for processing motor housings. Utility Model Content

[0012] This utility model provides a painting device for processing motor housings. It has the following beneficial effects:

[0013] This painting device for processing motor housings drives the spraying frame to reciprocate axially along the support platform via a movable seat. This allows the atomizing nozzle on the fixed extension rod to cover the length of the heat dissipation fins on the motor housing, and to spray the area between the two heat dissipation fins more comprehensively. When the servo motor of the swing component drives the rotating column to continuously move the movable extension rod, it causes the atomizing nozzle at its end to periodically deflect and swing. This allows the painting trajectory on the upper part of the motor housing to have both axial scanning and radial expansion capabilities, resulting in more comprehensive painting of the outer wall of the motor housing.

[0022] 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.

[0023] like Figure 1-5As shown, a painting device for processing motor housings includes a support platform 3, a movable seat 4 slidably mounted on the upper surface of the support platform 3, a processing table 2 arranged on the outer side of the support platform 3, a suspension guide rail 6 arranged above the processing table 2, multiple lifting rings 10 slidably mounted on the suspension guide rail 6, hooks 11 arranged at the lower end of the lifting rings 10, and the lifting rings 10 suspend the motor housing 12 through the hooks 11. A painting frame 8 is fixedly connected to the outer wall of the movable seat 4, multiple fixed extension rods 9 are fixedly mounted on the inner wall of the painting frame 8, two symmetrically arranged movable extension rods 14 are movably mounted on the top inner wall of the painting frame 8, and swing components are installed on the inner wall of the painting frame 8 at positions corresponding to the movable extension rods 14, and the movable extension rods 14 are movably connected to the painting frame 8 through the swing components. Atomizing nozzles 13 are fixedly installed at the ends of rod 9 and the two movable extension rods 14. By driving the lifting ring 10 to slide along the suspension guide rail 6, the motor housing to be painted can be moved sequentially into the interior of the protective shell 1 for processing. The upper end of the spray frame 8 has a notch for use with the suspension guide rail 6. When the lifting ring 10 slides along the suspension guide rail 6, the hoisted motor housing 12 can be moved into the interior of the spray frame 8 through the hook 11. The interior of the spray frame 8 is equipped with multiple atomizing nozzles 13 distributed around the motor housing 12. The atomizing nozzles 13 can spray the atomized paint onto the outer wall of the motor housing 12. The multiple atomizing nozzles 13 distributed around the motor housing 12 can spray the outer wall of the motor housing 12 more comprehensively. When the outer wall is painted, the movable seat 4 reciprocates on the upper surface of the support platform 3, thereby driving the spraying frame 8 to reciprocate along the length of the heat dissipation fins on the outer wall of the motor housing 12. During the back-and-forth sliding process, the spraying frame 8 can spray the area between the two heat dissipation fins more comprehensively.

[0024] like Figure 5 As shown, the swing assembly includes a connecting seat 16 fixedly installed on the inner wall of the top of the spray frame 8. The upper end of the movable extension rod 14 is rotatably connected to the connecting seat 16. A rotating column 15 is rotatably connected to the outer wall of the connecting seat 16 at a position corresponding to the rotation axis of the movable extension rod 14. A protrusion 17 is fixedly installed on the outer wall of the rotating column 15. A rotating disk 19 is rotatably installed on the upper half of the outer wall of the spray frame 8 at a position corresponding to the rotating column 15. A lever 18 that cooperates with the protrusion 17 is fixedly installed on the outer wall of the rotating disk 19. When the rotating disk... When the rotating disk 19 rotates once, the protrusion 17 can be moved by the toggle block 18 fixedly installed on its outer wall. The rotating disk 19 continues to rotate until the toggle block 18 separates from the protrusion 17. When the protrusion 17 loses external pressure, the movable extension rod 14 can swing back to its original position under the action of gravity. Under the combined action of the toggle block 18 and gravity, the movable extension rod 14 remains in a swinging state, thereby expanding the painting range of the atomizing nozzle 13 located at the end of the movable extension rod 14, so that the upper outer wall of the motor housing 12 is painted more comprehensively.

[0025] like Figure 5 As shown, a fixed frame is also fixedly installed on the outer wall of the spraying frame 8. A servo motor 20 is fixedly installed on the fixed frame. The output end of the servo motor 20 is fixedly connected to the center position of the rotating disk 19. The rotating disk 19 is rotated by the servo motor 20, and the movable extension rod 14 can swing by the continuous rotation of the rotating disk 19.

[0026] like Figure 3 As shown, a protective shell 1 is fixedly installed on the upper surface of the processing table 2 outside the spraying frame 8, and an auxiliary rail 7 is fixedly installed on the lower end of the inner wall of the protective shell 1. The protective shell 1 can prevent the paint after atomization during the painting process from spreading in the working area, and the auxiliary rail 7 can support the lower end of the spraying frame 8 away from the movable seat 4.

[0027] like Figure 2 As shown, multiple rollers are rotatably connected to the upper surface of the auxiliary track 7, and the bottom surface of the spray frame 8 contacts the outer wall of the multiple rollers; the multiple rollers can convert the sliding friction between the bottom surface of the spray frame 8 and the upper surface of the auxiliary track 7 into rolling friction, thereby reducing the resistance when the spray frame 8 slides on the upper surface of the auxiliary track 7, making the spray frame 8 slide more smoothly along the upper surface of the auxiliary track 7.

[0028] like Figure 3 As shown, a storage box 5 is fixedly installed on the upper surface of the movable seat 4. A conveying pipe is fixedly connected to the storage box 5, and the other end of the conveying pipe is connected to multiple atomizing nozzles 13. The conveying pipe is flexible and can convey the paint stored in the storage box 5 to multiple atomizing nozzles 13. The paint is then sprayed onto the outer wall of the motor housing 12 through the atomizing nozzles 13.

[0029] like Figure 2 As shown, an electric slide rail is fixedly installed on the upper surface of the support platform 3, and an electric slide table is slidably connected on the electric slide rail. The movable seat 4 is fixedly installed on the upper surface of the electric slide table. The electric slide table is driven by electricity to reciprocate along the electric slide rail, thereby driving the movable seat 4 to reciprocate on the upper surface of the support platform 3.

[0030] The working principle of this utility model is as follows: During use, by driving the lifting ring 10 to slide along the suspension guide rail 6, the motor housing to be painted can be moved sequentially into the protective shell 1 for processing. The notch at the upper end of the spray frame 8 cooperates with the suspension guide rail 6. When the lifting ring 10 slides along the suspension guide rail 6, the hoisted motor housing 12 can be moved into the spray frame 8 via the hook 11. The spray frame 8 is equipped with multiple atomizing nozzles 13 distributed around the motor housing 12. The storage box 5 stores paint, and the paint inside the storage box 5 is conveyed to the multiple atomizing nozzles 13 through a delivery pipe. The paint is then applied to the motor housing 12... When painting the outer wall, the electric slide table slides along the electric slide rail set on the upper surface of the support platform 3. The electric slide table can drive the movable seat 4 to reciprocate, which in turn drives the spraying frame 8 to reciprocate along the length direction of the heat dissipation fins set on the outer wall of the motor housing 12. During the back-and-forth sliding process, the spraying frame 8 can spray the area between the two heat dissipation fins more comprehensively. At the same time, the two sets of swing components set on the top of the spraying frame 8 can drive the two movable extension rods 14 to swing. During the swinging process, the movable extension rods 14 can expand the space at the end of the movable extension rods 14. The spraying range of the atomizing nozzle 13 is such that the atomizing nozzle 13 located at the end of the movable extension rod 14 can spray the upper outer wall of the motor housing 12 more comprehensively. After the painting process, the motor housing 12 can be moved along the suspension guide rail 6 under the action of the lifting ring 10 to the outside of the protective housing 1 and enter the next processing step. The sliding of 10 on 6 in this device is an existing mature technology, which will not be described in detail here. The cooperation between the electric slide rail and the electric slide table in this device, as well as the process of the lifting ring 10 sliding along the suspension guide rail 6, are all controlled by the PLC controller.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
