[0001] This utility model relates to the technical field of automated equipment for spraying the surface of drive shafts, specifically an automated equipment for spraying the surface of drive shafts. Background Technology

[0002] The driveshaft is a crucial component in an automotive transmission system, and the quality of its surface coating directly affects the quality and lifespan of the driveshaft assembly. Substandard coatings can cause corrosion on the driveshaft surface, affecting its appearance and, more seriously, reducing its lifespan and performance.

[0003] In existing drive shaft surface spraying processes, the drive shaft is usually conveyed by a feeding line before spraying. However, the feeding line typically requires a hanging device to fix the drive shaft before conveying it into the spraying chamber. This requires manual connection of the drive shaft to the hanging device for conveying. During the conveying process, the drive shaft will sway due to the hanging device, which may cause collisions and injuries to personnel if they get close. In addition, manual hanging is inefficient. Therefore, we propose an automated equipment device for drive shaft surface spraying to solve the above-mentioned problems. Utility Model Content

[0008] As a preferred embodiment of this utility model, the top of the movable plate is provided with multiple sets of cylindrical buffers, and an arc-shaped receiving plate is provided above the cylindrical buffers.

[0009] As a preferred technical solution of this utility model, a shell is provided at the center of the spraying chamber, and a third cylinder is provided inside the shell. The output end of the third cylinder is connected to the bottom of the third top plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When using the automated equipment for spraying the surface of drive shafts, multiple drive shafts are placed above the guide rack. After the drive shaft rolls to one side, it contacts the first guide plate. At this time, the first cylinder drives the moving plate to move, causing the first top plate and the second top plate to move upward. The first top plate pushes a single drive shaft upward and then rolls it to one side in conjunction with the first guide plate. Since the second top plate is also lifted at the same time, it blocks the drive shaft. When the first top plate and the second top plate are lowered, the drive shaft enters the placement slot above the support base. Repeating the above operation to push a new drive shaft upward, the second top plate lifts the drive shaft in the placement slot and it enters the guide rack. Since the guide rack is slightly tilted, the drive shaft slowly rolls to one side and enters the spraying chamber to complete the spraying. This reduces manual operation for conveying the drive shaft and improves efficiency. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-6This utility model provides a technical solution: an automated equipment for spraying the surface of a drive shaft, comprising a guide frame 1, a conveyor frame 2, and a spraying chamber 3. The guide frame 1 and the conveyor frame 2 are connected by a support frame 4. The conveyor frame 2 is inclined to one side of the spraying chamber 3, and the spraying chamber 3 is located on the right side of the conveyor frame 2. A heating air box 31 is provided at the bottom of the spraying chamber 3, and the heating air box 31 is connected to the interior of the spraying chamber 3 through an air inlet pipe 30. Two sets of fixed seats 13 are provided inside the spraying chamber 3. Two sets of second cylinders 14 are provided on both sides inside the two sets of fixed seats 13. The output end of the second cylinder 14 is connected to a mounting plate 32, and the mounting plate 32 is slidably connected to the fixed seat 13. Multiple sets of cylindrical buffers 15 are provided at the top of the mounting plate 32, and an arc-shaped receiving plate 16 is provided above the cylindrical buffers 15. The spraying chamber 3... The interior is equipped with a housing 17 at its center, and a third cylinder 18 is located inside the housing 17. The output end of the third cylinder 18 is connected to the bottom of the third top plate 19. Two sets of rotating shafts 20 are rotatably provided on both sides of the spray chamber 3. Drive gears 21 are installed on both sets of rotating shafts 20 and mesh with each other. A transmission wheel 22 is installed at the front end of the rotating shaft 20. A drive groove 23 is provided inside the spray chamber 3. A lead screw 24 is located at the center of the drive groove 23 and is rotatably connected to the spray chamber 3. A slider 25 is slidably provided inside the drive groove 23 and is threadedly connected to the lead screw 24. A nozzle 26 is located at the front end of the slider 25 and is connected to an external material supply system. An assembly plate 27 is provided inside the spray chamber 3, and an inclined second guide plate 28 is located at the top of the assembly plate 27.

[0023] In use, multiple drive shafts are placed above the guide frame 1. As the guide frame 1 tilts to one side, the drive shafts will roll to one side. After the drive shafts roll to one side, they come into contact with the first guide plate 29. At this time, the first cylinder 5 drives the moving plate 6 to move, so that the moving plate 6 drives the first top plate 7 above to slide in the first moving groove 8 inside the guide frame 1. At the same time, the connecting rod 9 on the right side of the moving plate 6 drives the second top plate 10 to slide in the second moving groove 11 inside the support frame 4. At this time, the first top plate 7 pushes one drive shaft upward and then rolls to one side in conjunction with the first guide plate 29. As the second top plate 10 is also pushed up, it blocks the drive shaft. When the first top plate 7 and the second top plate 10 move downward, the drive shaft enters the placement groove 12 above the support frame 4. Repeat the above operation to push the new drive shaft upward. At this time, the second top plate 10 pushes the drive shaft in the placement groove 12 and then enters the conveyor frame 2. As the conveyor frame 2 is slightly tilted, the drive shaft slowly rolls to one side.

[0024] The guide frame 1 has a support frame 4 on the right side, and two sets of first cylinders 5 on the top left side of the support frame 4. The output end of the first cylinder 5 is connected to a moving plate 6. The top of the moving plate 6 is a first top plate 7. The left side of the guide frame 1 has a first moving groove 8 for moving the first top plate 7. The two ends of the right side of the moving plate 6 have connecting rods 9. The top of each of the two sets of connecting rods 9 is a second top plate 10. The support frame 4 has a second moving groove 11 for moving the second top plate 10. The left side wall of the support frame 4 has a first guide plate 29. The top of the support frame 4 has a placement groove 12.

[0025] The material falls onto the curved receiving plate 16 to catch the drive shaft. Because the surface of the curved receiving plate 16 has an anti-slip layer, it prevents excessive rolling of the drive shaft. Simultaneously, the cylindrical buffer 15 cushions the impact of the drive shaft falling onto the curved receiving plate 16, preventing excessive impact force. The cylindrical buffer 15 is a common small buffer found on the market. At this point, the second cylinder 14 drives the mounting plate 32 to descend, simultaneously lowering the drive shaft above the curved receiving plate 16 into the spray booth 3. After the drive shaft is positioned between the two sets of transmission wheels 22 on both sides, the surface of the drive shaft is sprayed through the spray nozzle 26. Simultaneously, during the spraying process, the motor drives a single rotating shaft 20 to rotate, and the drive gear 21 above the rotating shaft 20 rotates synchronously. The drive gears 21 on both sides synchronously drive the rotating shafts 20 on both sides to rotate, and the rotating shafts 20 drive the transmission wheels 22 to rotate. This rotation of the drive shaft through the transmission wheels 22 facilitates spraying different positions on the surface of the drive shaft by the spray nozzle 26. During spraying, the motor drives the lead screw 24 to rotate. Rotation of the lead screw 24 causes the slider 25 to slide inside the drive groove 23, which in turn moves the front spray nozzle 26, facilitating spraying at different positions on the drive shaft surface. Simultaneously, during spraying, the heating air box 30 draws in filtered external air via a fan, heats it, and then introduces it into the spray chamber 3 through the air inlet duct 30. This raises the temperature inside the spray chamber 3, improving the curing efficiency of the sprayed material. The fan inside the heating air box 30 has a low power, keeping the airflow into the air inlet duct 30 low, so as not to affect the spraying effect of the spray nozzle 26. To improve curing, after the spraying is completed, the third cylinder 18 inside the housing 17 drives the third top plate 19 to move. Since the third top plate 19 is tilted, the drive shaft is lifted by the third top plate 19 and rolled to one side before entering the second guide plate 28 and rolling out of the spraying chamber 3. Since the raw material sprayed on the surface has been pre-cured during the spraying process, it can prevent the raw material from falling off during the rolling process above the second guide plate 28. At the same time, the tilt angle of the second guide plate 28 is small, which can prevent the coating from peeling off due to the excessive rolling speed of the drive shaft.

[0026] Working Principle: When using the automated equipment for spraying the surface of drive shafts, multiple drive shafts are placed above the guide frame 1. Because the guide frame 1 tilts to one side, the drive shafts roll to that side. After rolling to one side, the drive shaft contacts the first guide plate 29. At this time, the first cylinder 5 drives the moving plate 6 to move, causing the moving plate 6 to slide the first top plate 7 inside the first moving groove 8 of the guide frame 1. Simultaneously, the connecting rod 9 on the right side of the moving plate 6 drives the second top plate 10 to slide in the second moving groove 11 inside the support frame 4. At this time, the first top plate 7 pushes one drive shaft upwards and, together with the first guide plate 29, rolls it to one side. Because the second top plate 10 also pushes it up, it blocks the drive shaft. When the first top plate 7 and the second top plate 29 are in motion... After the top plate 10 moves downward, the drive shaft enters the placement slot 12 above the support frame 4. Repeating the above operation to push the new drive shaft upward, the second top plate 10 lifts the drive shaft from the placement slot 12 and places it into the conveyor frame 2. Due to the slight tilt of the conveyor frame 2, the drive shaft slowly rolls to one side and falls onto the arc-shaped receiving plate 16 to receive it. The arc-shaped receiving plate 16 has an anti-slip layer to prevent excessive rolling of the drive shaft. Simultaneously, the cylindrical buffer 15 cushions the arc-shaped receiving plate 16 as the drive shaft falls, preventing excessive impact from the drive shaft. The cylindrical buffer 15 is a common small buffer found on the market. At this time, the second cylinder 14 drives the mounting plate 32 to descend. After the drive shaft above the arc-shaped receiving plate 16 descends and enters the spraying chamber 3, it is positioned between the two sets of drive wheels 22 on both sides. The spray nozzle 26 then sprays the surface of the drive shaft. Simultaneously, during spraying, the motor drives a single rotating shaft 20 to rotate, and the drive gear 21 above the rotating shaft 20 rotates synchronously. The drive gears 21 on both sides synchronously drive the rotating shafts 20 on both sides to rotate, and the rotating shafts 20 drive the drive wheels 22 to rotate. This rotation of the drive shaft, via the drive wheels 22, facilitates spraying different positions on the drive shaft surface by the spray nozzle 26. During spraying, the motor drives the lead screw 24 to rotate. The lead screw 24 drives the slider 25 to slide inside the drive groove 23, which in turn moves the front spray nozzle 26, facilitating... Spraying is performed on different positions on the surface of the drive shaft. Simultaneously, during spraying, the heating air box 30 draws in filtered external air via a fan, heats it, and then introduces it into the spraying chamber 3 through the air inlet duct 30. This raises the temperature inside the spraying chamber 3, improving the curing efficiency of the sprayed material. The fan inside the heating air box 30 has a low power, keeping the airflow into the air inlet duct 30 low, which does not affect the spraying effect of the nozzle 26 while improving curing. After spraying, the third cylinder 18 inside the housing 17 moves the third top plate 19. Due to the inclined design of the third top plate 19, the drive shaft is lifted by the third top plate 19 and rolled to one side, entering above the second guide plate 28 and then rolling out of the spraying chamber 3. Since the sprayed material has already undergone preliminary curing during the spraying process...This design prevents raw materials from falling off during rolling above the second guide plate 28. Furthermore, the smaller inclination angle of the second guide plate 28 prevents the coating from peeling off due to excessive rolling speed of the drive shaft, thus completing a series of tasks.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
