[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The following gives specific embodiments.

[0026] Please refer to Figure 1 - Figure 5 , the present invention provides a spraying device for a motor housing, including a box body 1 and a storage bin 2. A first bearing 11 is fixedly connected to an inner wall of one side of the box body 1, and a transmission rod 12 is fixedly connected to the inside of the first bearing 11. Two limiting plates 20 are fixedly connected to an outer wall of one end of the transmission rod 12, and a movable block 16 is arranged on one side of each limiting plate 20. The inner wall of each movable block 16 is slidably connected to the outer wall of the transmission rod 12, and a plurality of connecting rods 17 are rotatably connected to the outer wall of each movable block 16, and the plurality of connecting rods 17 are arranged in an array. And the plurality of connecting rods 17 are symmetrically arranged on the outside of the transmission rod 12 through the two movable blocks 16, and a positioning block 18 is rotatably connected to the middle of every two connecting rods 17; two second motors 13 are fixedly connected to one side of the middle of the box body 1, and a driven wheel 14 is fixedly connected to one end of an output shaft of one second motor 13. A transmission belt 15 is rotatably connected to the outer wall of the driven wheel 14, the other end of the transmission belt 15 is rotatably connected to the inner wall of another driven wheel 14, and the inner wall of the other driven wheel 14 is fixedly connected to the outer wall of one end of the transmission rod 12. A pump 3 is fixedly connected to the top of the storage bin 2, and a feeding pipe 4 is fixedly connected to one end of the pump 3. The other end of the feeding pipe 4 is fixedly connected to a connecting block 5, and a nozzle 6 is fixedly connected to the bottom of the connecting block 5. The nozzle 6 is arranged above the transmission rod 12 through the connecting block 5.

[0027] During operation, by sleeving the motor housing outside the transmission rod 12, the movement of the movable block 16 can be used to push one end of multiple connecting rods 17 to expand outward. Furthermore, the positioning block 18 can be pushed into contact with the inner wall of the motor housing, and the motor housing can be fixed outside the transmission rod 12. Then, the pump 3 is started, and the pump 3 is used to extract the paint inside the storage tank 2. Then, the paint is guided to the connecting block 5 through the feed pipe 4 and sprayed on the surface of the motor housing through the spray head 6. Then, a second motor 13 is started, and the output shaft of the second motor 13 is used to drive the driven wheel 14 to rotate. Furthermore, the drive belt 15 is driven to rotate, and another driven wheel 14 is driven to rotate synchronously by the drive belt 15, so that the transmission rod 12 rotates inside one end of the box body 1, and then the spraying position of the motor housing is adjusted. The first bearing 11 can not only improve the rotation efficiency of the transmission rod 12, but also improve the stability of the transmission rod 12. By adopting the above method, the cooperation of the movable block 16, the connecting rod 17 and the positioning block 18 is used to make the outer wall of the positioning block 18 fit with the inner wall of the motor housing, and then the motor housing is clamped and fixed to prevent missed spraying when spraying the surface of the motor housing. Moreover, the rotation of the transmission rod 12 drives the motor housing to rotate, which can reduce the time consumed for spraying the motor housing and improve the spraying efficiency of the motor housing.

[0028] Furthermore, as Figure 3 shown, a chute 7 is opened at the top of the box body 1, and two first motors 8 are fixedly connected to the inner wall of one end at the top of the box body 1. One end of the output shaft of each first motor 8 is fixedly connected with a first threaded rod 9, and both ends of the first threaded rod 9 are rotatably connected to the inner walls on both sides of the chute 7. The outer wall of each first threaded rod 9 is threadedly connected with a slider 10, and each slider 10 is slidably connected to the inner wall of the chute 7 through the first threaded rod 9. And one side of each slider 10 is fixedly connected with the connecting block 5, and the connecting block 5 is slidably connected to the inner wall of the chute 7 through the two sliders 10.

[0029] During operation, by starting the two first motors 8, the output shafts of the first motors 8 are used to drive the first threaded rods 9 to rotate simultaneously. And the rotation of the first threaded rods 9 can drive the sliders 10 to slide on the inner walls at both ends of the chute 7. Then, by the fixed connection between the sliders 10 and the connecting block 5, the connecting block 5 can be driven to slide on the inner wall of the chute 7, driving the spray head 6 to move horizontally on the top of the motor housing, and the spraying position of the motor housing can be quickly adjusted to meet the spraying requirements of motor housings of different sizes.

[0030] Furthermore, as Figure 4 and Figure 5As shown in the figure, a through groove 21 is formed inside the transmission rod 12, and a second threaded rod 22 is rotatably connected inside the through groove 21. A limiting block 19 is rotatably connected to the middle of the second threaded rod 22, and the outer wall of the limiting block 19 is fixedly connected to the inner wall of the transmission rod 12. One end of the second threaded rod 22 is fixedly connected to one end of the output shaft of a second motor 13. Connecting plates 23 are threadedly connected to both ends of the through groove 21, and the outer wall of each connecting plate 23 is slidably connected to the inner wall of the through groove 21 via the second threaded rod 22. A second bearing 24 is fixedly connected to the outside of each connecting plate 23, and each second bearing 24 is slidably connected to the outer wall of the transmission rod 12 via the connecting plate 23. The outer wall of each second bearing 24 is fixedly connected to the inner wall of one end of the movable block 16.

[0031] During operation, by starting another second motor 13, the output shaft of the second motor 13 is used to drive the second threaded rod 22 to rotate on the inner wall of the through groove 21, so that the two connecting plates 23 can slide on the inner wall of the through groove 21. The limiting block 19 is used to prevent the two connecting plates 23 from colliding during movement. By virtue of the fixed connection between the outside of the connecting plate 23 and the second bearing 24, and then by virtue of the fixed connection between the outer wall of the second bearing 24 and the movable block 16, the connecting plate 23 can drive the movable block 16 and the second bearing 24 to slide on the outer wall of the transmission rod 12 when moving. By the movement of the two movable blocks 16, multiple connecting rods 17 can be pushed to expand outwards, so that the positioning block 18 contacts the inside of the motor housing. And as the distance between the two movable blocks 16 is adjusted, the fixing requirements of motor housings of different sizes can be met, the practicability and use efficiency of the device can be improved, and thus the spraying efficiency of the motor housing can be improved.

[0032] Working principle: By sleeving the motor housing on the outside of the transmission rod (12), the movement of the movable block (16) can be used to push one end of multiple connecting rods (17) to expand outward, and then the positioning block (18) can be pushed into contact with the inner wall of the motor housing, so that the motor housing can be fixed on the outside of the transmission rod (12).

Then start a second motor (13), use the output shaft of the second motor (13) to drive the driven wheel (14) to rotate, and then drive the transmission belt (15) to rotate, and then use the transmission belt (15) to drive another driven wheel (14) to rotate synchronously, so that the transmission rod (12) rotates inside one end of the box body (1), and then adjust the spraying position of the motor housing. The first bearing (11) can not only improve the transmission efficiency of the transmission rod (12), but also improve the stability of the transmission rod (12). By adopting the above method, the cooperation of the movable block (16), the connecting rod (17) and the positioning block (18) is used to make the outer wall of the positioning block (18) fit with the inner wall of the motor housing, so as to clamp and fix the motor housing and prevent missed spraying when spraying the surface of the motor housing. And the rotation of the transmission rod (12) drives the rotation of the motor housing, which can reduce the time consumed for spraying the motor housing and improve the spraying efficiency of the motor housing.
