When spraying, the paint spraying head rotates around the motor housing. When spraying, the distance between the paint spraying head and the workpiece should be kept at about 20 cm, because too close or too far a distance may cause uneven coating. However, when spraying around the housing, it is difficult to ensure that the axis of the housing coincides with the axis of rotation of the paint spraying head, resulting in uneven spraying on the outer shell. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Example 1: Refer to Figures 1-3, A spraying device for the surface of a motor housing, comprising a base 1. The base 1 is connected to a rotating disk 2 through a rotating mechanism. The rotating mechanism includes a motor 15, which is fixedly connected to the base 1. A rotating shaft 16 is fixedly connected to the output shaft of the motor 15, and the rotating shaft 16 is fixedly connected to the rotating disk 2. The motor 15 drives the rotating shaft 16 to rotate, thereby causing the rotating disk 2 to rotate.

[0019] A plurality of limiting sleeves 7 are fixedly connected to the rotating disk 2 at equal distances in the circumferential direction. Abutting blocks 5 can be inserted into the plurality of limiting sleeves 7. Articulated rods 6 are hinged to the plurality of abutting blocks 5. The plurality of articulated rods 6 are hinged to a moving ring. A hydraulic rod 3 is fixedly connected to the moving ring. The hydraulic rod 3 is fixedly connected to a column 4, and the column 4 is fixedly connected to the rotating disk 2. A painting mechanism is arranged on the rotating disk 2 through an adjusting mechanism. The housing is in a circular sleeve state. By sleeving the housing on the column 4, the hydraulic rod 3 expands and contracts, driving the moving ring to move, thereby adjusting the inclination angle of the articulated rod 6, and then driving the abutting block 5 to move, so that the abutting block 5 abuts against the inner wall of the housing, making the axis of the housing coincide with the axis of the rotating disk 2. Thus, when spraying, the distance between the paint spraying head and the outer wall of the housing is constant, ensuring the uniformity of spraying and thus ensuring the effect of paint spraying.

[0020] The painting mechanism includes a housing 9. A plurality of nozzles 8 are communicated with the housing 9. A connecting ear 20 is fixedly connected to the housing 9. A threaded column 12 is fixedly connected to the connecting ear 20. A threaded sleeve 11 is threadedly connected to the threaded column 12. The threaded sleeve 11 is rotatably connected to a connecting frame 14 through a bearing. The connecting frame 14 is fixedly connected to the base 1. The housing 9 is limited by a limiting mechanism. The housing 9 is connected to a liquid supply mechanism. By rotating the threaded sleeve 11, the position of the threaded column 12 in the threaded sleeve 11 is adjusted, thereby adjusting the distance between the nozzle 8 and the outer wall of the housing, so as to spray housings of different diameters and control the spraying distance at 20 cm.

[0021] The liquid supply mechanism includes a connecting pump 17, which is installed on the base 1. The connecting pump 17 is connected to the housing 9 through a connecting pipe 19. A placing cylinder 18 is placed on the base 1. The placing cylinder 18 is connected to the connecting pump 17 through a conduit. The connecting pump 17 is the power source for paint spraying.

[0022] The limiting mechanism includes a limiting rod 13, which is fixedly connected to the connecting ear 20. The limiting rod 13 penetrates through the connecting frame 14. The limiting rod 13 is used to play a limiting role to prevent the connecting ear 20 from rotating during adjustment.

[0023] When in use: By sleeving the casing on the column 4, the hydraulic rod 3 expands and contracts to drive the moving ring to move, thereby adjusting the inclination angle of the hinge rod 6, and then driving the abutting block 5 to move, so that the abutting block 5 abuts against the inner wall of the casing. By rotating the threaded sleeve 11, the position of the adjusting threaded column 12 in the threaded sleeve 11 is adjusted, thereby adjusting the distance between the nozzle 8 and the outer wall of the casing. Finally, the rotating disc 2 is started to rotate, and at the same time, the connecting pump 17 is opened to spray paint.

[0024] Embodiment 2: In Embodiment 1, since the lengths of casings of different sizes are different, the number of nozzles 8 opened cannot be adjusted. When spraying a shorter casing, it is easy to cause waste of paint. Refer to Figures 1-3 , as another preferred embodiment of the present invention, on the basis of Embodiment 1, a plurality of valves 10 are equidistantly arranged on the housing 9. Through the design of the valves 10, they can be switched on and off to control the number of nozzles 8 opened according to the length of the casing, thereby avoiding waste of paint.

[0025] Embodiment 3: Refer to Figures 1-3 , as another preferred embodiment of the present invention, on the basis of Embodiment 1, a U-shaped seat is rotatably connected to the rotating shaft 16 through a slewing bearing, and the U-shaped seat is fixedly connected to the base 1. By adopting the U-shaped seat and the slewing bearing, the bearing of the rotating disc 2 and the rotating shaft 16 is supported.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
