[0027] Embodiment 1:

[0028] As Figures 1 to 8 shown, a spraying device for the processing surface of a three-lobe spring according to the present utility model includes a main chassis 1. A pair of left and right relative support rings 23 are fixedly connected to the inner side of the main chassis 1. The support rings 23 are fixed by the main chassis 1. The main shaft 21 is rotatably connected to the inner side of the support rings 23. The main shaft 21 is limited by the support rings 23. A power component is arranged at the front end of the main shaft 21. The same moving components are arranged at the top and front end of the main shaft 21. A limiting groove 22 is formed in the outer wall of the main shaft 21. A gear 41 is arranged at the front end of the front moving component. An air pump 42 is fixedly connected to the middle side of the front end of the gear 41. The air pump 42 is fixed by the gear 41. A limiting sleeve 43 is fixedly connected to the front end of the air pump 42. The limiting sleeve 43 is fixed by the air pump 42. An airbag 45 is fixedly connected to the inner side of the limiting sleeve 43. The airbag 45 is fixed by the limiting sleeve 43. The airbag 45 is communicated with the air pump 42 through an air delivery pipe 44. The air pump 42 uses the air delivery pipe 44 to deliver gas into the airbag 45. A uniformly distributed extrusion plate 46 is fixedly connected to the outer side of the airbag 45. The extrusion plate 46 is slidably connected to the limiting sleeve 43. The extrusion plate 46 is limited by the limiting sleeve 43. At the same time, the airbag 45 expands to push the extrusion plate 46 outward. A workpiece 5 is slidably connected to the outer side of the limiting sleeve 43. The inner side wall of the workpiece 5 is slidably connected to the extrusion plate 46. The extrusion plate 46 moves outward, so as to expand and tighten the inner side of the workpiece 5, thereby fixedly connecting the limiting sleeve 43 and the workpiece 5.

[0029] The power component includes a support plate 13. The support plate 13 is fixedly connected to the left bottom end of the main chassis 1. The support plate 13 is fixed by the main chassis 1. A motor 2 is fixedly connected to the top end of the support plate 13. The motor 2 is fixed by the support plate 13. The output end of the motor 2 is fixedly connected to the main shaft 21. The main shaft 21 is driven to rotate by the motor 2.

[0030] The moving component includes a limiting frame 3. The inner side wall of the support ring 23 is fixedly connected to the limiting frame 3, and the limiting frame 3 is fixed by the support ring 23. A chute 34 is provided in the middle of the inner side of the limiting frame 3. A slide bar 31 is fixedly connected to the inner side of the chute 34. The slide bar 31 is fixed in the chute 34. A limiting ball 33 is slidably connected to the outer side of the slide bar 31. The slide bar 31 limits the limiting ball 33. The limiting ball 33 is slidably connected to the limiting groove 22. The motor 2 drives the main shaft 21 and the limiting groove 22 to rotate simultaneously, so as to limit the limiting ball 33 through the limiting groove 22, thereby driving the limiting ball 33 to move left and right. The limiting ball 33 is slidably connected to the limiting frame 3, and the top of the limiting ball 33 is limited by the limiting frame 3. A spring 32 is fixedly connected to the outer end of the right side of the limiting ball 33, and the right side of the spring 32 is fixedly connected to the inner wall of the chute 34. The spring 32 connects the limiting ball 33 and the chute 34, so that when the limiting ball 33 moves to the straight part of the limiting groove 22 at the rightmost side, the spring 32 can push the limiting ball 33 to move to the leftmost side with the limiting frame 3 as the stress point, thus realizing the function of reciprocating operation.

[0031] At the rear side of the top of the top limiting frame 3, a paint box 25 is fixedly connected. The top limiting frame 3 fixes the paint box 25. At the top left side of the paint box 25, a blanking pipe 26 is fixedly connected. The paint box 25 fixes the blanking pipe 26. A sealing cover 27 is threadedly connected to the top of the blanking pipe 26. The sealing cover 27 seals the top of the blanking pipe 26. At the top side of the middle of the paint box 25, a connecting hose 28 is fixedly connected. At the bottom side of the front end of the connecting hose 28, a delivery pump 29 is fixedly connected. The connecting hose 28 connects the paint box 25 and the delivery pump 29. The delivery pump 29 is fixedly connected to the top limiting ball 33.

At the bottom side of the front end of the shunt pipe 24, an atomizing nozzle 210 is fixedly connected. The shunt pipe 24 connects the delivery pump 29 and the atomizing nozzle 210.

[0032] At the bottom side of the front of the front limiting frame 3, a rack 4 is fixedly connected. The rack 4 is meshed with a gear 41. The gear 41 is rotatably connected to the front limiting ball 33. The front limiting ball 33 drives the gear 41 to move left and right at the top of the rack 4, so as to rotate, thereby driving the front structure of the gear 41 and the workpiece 5 to rotate.

[0033] The inner side of the top of the main chassis 1 is rotatably connected to a cabinet door 11, and a handle 12 is fixedly connected to the front end of the cabinet door 11.

[0034] Working principle: When the spraying device for the processing surface of the three-lobe spring is operating, first, the workpiece 5 is sleeved outside the limit sleeve 43. Then, the air pump 42 uses the air delivery pipe 44 to deliver gas into the airbag 45, causing the airbag 45 to expand. At the same time, the airbag 45 squeezes the pressing plate 46, forcing the pressing plate 46 to move outward to tighten and fix the workpiece 5, completing the fixation of the inner side of the workpiece 5. After that, the motor 2 drives the main shaft 21 and the limit groove 22 to rotate synchronously. The limit ball 33 is limited by the limit groove 22 and the limit frame 3, so that the limit ball 33 moves left and right while the main shaft 21 rotates. The top limit ball 33 drives the delivery pump 29, the shunt pipe 24, and the atomizing nozzle 210 to move to the right. At the same time, the delivery pump 29 uses the connecting hose 28 to extract the paint inside the paint tank 25. The paint is shunted through the shunt pipe 24 and enters the atomizing nozzle 210 for atomized spraying. The front limit ball 33 drives the gear 41 to move on the top of the rack 4. The rack 4 limits the gear 41, so that the gear 41 rotates self - synchronously during the rightward movement. The self - rotation of the gear 41 drives the front air pump 42, other structures, and the workpiece 5 to rotate synchronously. Through cooperation with the top atomizing nozzle 210, the uniform spraying of the outer surface of the workpiece 5 is completed. After the spraying is finished, the workpiece 5 is removed by external equipment. The limit ball 33 continues to move to the right. When the limit ball 33 moves to the straight part of the limit groove 22 on the rightmost side, the spring 32 pushes the limit ball 33 to move to the leftmost side with the limit frame 3 as the stress point, thus realizing the function of reciprocating operation and continuing to spray the next workpiece 5.

Taking the perspective of the observer as the standard, the side of the device facing the observer is defined as the front, and the left side of the observer is defined as the left, and so on.
