Description
Technical Field
[0001] The present invention relates to the technical field of air bucket welding, and specifically relates to an air bucket welding device. Background Art
[0002] An air bucket welding device is a device used to assist in welding the lid and the body of an air bucket. First, the body and the lid of the bucket are respectively placed between two driving rollers and two driven rollers, and the welding surfaces of the lid and the body are docked. Then, the motor drives the rotation of the rotating shaft, and the rotating shaft drives the two driving rollers thereon to rotate. Through the friction between the driving rollers and the body and the lid of the bucket, the two driving rollers respectively drive the body and the lid of the bucket to rotate synchronously. During the welding process, there is no need for manual rotation of the body and the lid by workers, and the body and the lid can maintain good consistency during the rotation process. Only one welder is required to complete the welding of the lid and the body of the air bucket.
[0003] During the actual welding process of an air bucket, since the end face of the lid is usually arc-shaped, the contact area between it and the driving rollers and the driven rollers is small, resulting in a small support point for the lid by the driving rollers and the driven rollers during rotation. The lid is prone to angular deviation during rotation, and there is no external force to ensure that the welding surfaces of the body and the lid always remain aligned. When the lid deviates, it is very likely to drive the body to displace, and the welding surfaces of the lid and the body cannot be aligned, affecting the welding accuracy and the dimensional accuracy of the finished product. The already welded parts may also deform with the deviation of the lid. For this reason, we propose an air bucket welding device. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] 1. The present invention utilizes the gravity of the barrel cover to deform the elastic band. The two fixed rings will abut against the lower end of the barrel cover, and the two annular plates will abut against the arc surface of the barrel cover. According to the different arcs of the barrel cover, the annular plates will be pushed by the arc surface of the barrel cover. After the elastic band deforms, it can closely adhere to the arc surface of the barrel cover, providing sufficient support for the barrel cover. When the rotating shaft rotates, it will drive the fixed ring to rotate. Through the limitation of the sliding ring by the limiting strip, the sliding ring will rotate synchronously with the fixed ring, and the elastic band will also rotate synchronously. The barrel cover is driven to rotate through the friction between the elastic band and the barrel cover, and the stability of the barrel cover during rotation is improved through the support of the fixed ring and the sliding ring for the barrel cover;
[0018] 2. The present invention utilizes the elastic force of the telescopic rod to make the rotating plate push the barrel body towards the barrel cover. Since the limiting ball provides stable support for the barrel cover, the barrel cover and the barrel body will always remain in close contact, improving the stability of the connection between the barrel cover and the barrel body during welding. When the barrel body rotates, since the fixed rod is always located at the middle position between the sliding part and the rotating shaft, the central axes of the fixed plate, the pushing plate, and the rotating plate will always be consistent with the central axis of the barrel body. The barrel body and the rotating plate will not undergo relative sliding during rotation, improving the stability of the barrel body during rotation. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0028] 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.
[0029] Please refer to Figure 1-8, the present invention provides a technical solution: an air barrel welding device, including a footrest 1, two supports 3 are fixedly installed on the footrest 1, a rotating shaft 4 is rotatably installed between the two supports 3, and a motor 2 for driving the rotating shaft 4 is fixedly installed on the footrest 1. Two guiding bars 9 are fixedly installed on the footrest 1, a sliding member 10 is slidably installed on each guiding bar 9, a connecting rod 11 is fixedly connected between the two sliding members 10, an adjusting rod 12 is rotatably installed on the connecting rod 11, a threaded bar 13 is fixedly installed at the end of the adjusting rod 12, and a limiting seat 14 matching with the threaded bar 13 is fixedly installed on the footrest 1. According to the diameter of the air barrel to be welded, the distance between the sliding member 10 and the rotating shaft is adjusted. Rotate the adjusting rod 12. Through the cooperation of the threaded bar 13 at its end with the limiting seat 14 and the limitation of the guiding bar 9 on the sliding member 10, the adjusting rod 12 drives the connecting rod 11 and the two sliding members 10 to slide synchronously along the guiding bar 9, and due to the self-locking property of the thread, prevent the sliding member 10 from sliding during welding. A roller 15 is rotatably installed on each sliding member 10, and roller wheels 16 for limiting the barrel body are fixedly installed on the rotating shaft 4 and one of the roller shafts 15. Fixed rings 17 are fixedly installed on the other roller shaft 15 and the rotating shaft 4. A first spring 20 is fixedly installed on one side of each fixed ring 17, and a sliding ring 18 is fixedly installed at one end of each first spring 20. Each sliding ring 18 is sleeved on the corresponding rotating shaft 4 and roller shaft 15, and a number of limiting bars 22 for enabling the sliding ring 18 and the fixed ring 17 to rotate synchronously are fixedly installed on the rotating shaft 4 and the corresponding roller shaft 15. An annular plate 19 is fixedly installed on the outer wall of each sliding ring 18, and an elastic band 21 is fixedly connected between the outer wall of each annular plate 19 and the outer wall of the fixed ring 17. Each elastic band 21 is annularly arranged. Place the barrel body between the two roller wheels 16, place the barrel lid on the two elastic bands 21. The gravity of the barrel lid will cause the elastic band 21 to deform, and the two fixed rings 17 will press against the lower end of the barrel lid. At the same time, the two annular plates 19 will press against the arc surface of the barrel lid. And according to the different arcs of the barrel lid, the annular plate 19 will be pushed by the arc surface of the barrel lid, and the first spring 20 will be stretched. After the elastic band 21 deforms, it can closely adhere to the arc surface of the barrel lid and provide sufficient support for the barrel lid. After the motor 2 is started, it will drive the rotating shaft 4 to rotate. The rotating shaft 4 will drive the roller wheel 16 thereon to rotate. Through the friction between the roller wheel 16 and the barrel body, the barrel body will be driven to rotate, and the roller wheel 16 and the roller shaft 15 on the corresponding sliding member 10 will be driven to rotate. At the same time, the rotating shaft 4 will also drive the fixed ring 17 thereon to rotate. Through the limitation of the limiting bar 22 on the sliding ring 18, the sliding ring 18 and the fixed ring 17 will be driven to rotate synchronously, and the elastic band 21 will also rotate synchronously. Through the friction between the elastic band 21 and the barrel lid, the barrel lid will be driven to rotate, and through the support of the fixed ring 17 and the sliding ring 18 for the barrel lid, the stability of the barrel lid during rotation is improved.
[0030] Two slide rails 23 are fixedly installed on the footrest 1. A slider 24 is slidably installed in each slide rail 23. Each slider 24 is fixedly installed on the corresponding sliding member 10. A positioning block 26 is also slidably installed in each slide rail 23. A second spring 25 is fixedly connected between each positioning block 26 and the corresponding slider 24. A second spring 25 is also fixedly connected between each positioning block 26 and the inner wall of the corresponding slide rail 23. Ball bearings 41 are arranged on both sides of each slider 24 and both sides of each positioning block 26. Chute grooves 42 cooperating with the ball bearings 41 are arranged on the inner walls on both sides of each slide rail 23. When the adjusting rod 12 drives the two sliding members 10 to slide, the sliding members 10 will also drive the sliders 24 to slide synchronously in the slide rails 23. Since the second springs 25 are installed on both sides of the positioning block 26, the second springs 25 on both sides will always be in the same compressed or stretched state. When the slider 24 slides, the elastic forces of the second springs 25 on both sides will push the positioning block 26 to move, so that the positioning block 26 is always in the middle position between the slider 24 and the corresponding inner wall of the slide rail 23. And through the cooperation of the ball bearings 41 and the chute grooves 42, the friction between the slider 24 and the positioning block 26 during the sliding process can be reduced, and the accuracy of the sliding position of the positioning block 26 can be improved. A device box 27 is fixedly installed at the upper end of each positioning block 26. A screw rod 30 is rotatably installed in each device box 27. A limiting ring 28 matching the thread is slidably installed in each device box 27. A fixing rod 29 is fixedly installed on each limiting ring 28. A limiting groove 31 for guiding the fixing rod 29 is arranged on each device box 27. When the positioning block 26 moves, it will drive the device box 27 to move synchronously. When the screw rod 30 is rotated, through the cooperation of the limiting ring 28 and the screw rod 30, and the guiding of the limiting groove 31 to the fixing rod 29, it will control the fixing rod 29 to drive the limiting ring 28 to slide in the device box 27. Arc-shaped plates 32 and fixing plates 35 are respectively fixedly installed at the upper ends of the two fixing rods 29. A plurality of sleeves 33 are fixedly installed in the concave surface of the arc-shaped plate 32. The sleeves 33 are arranged in a circular pattern. And a limiting ball 34 for limiting the bucket lid is rotatably installed at one end of each sleeve 33. By adjusting the position of the fixing rod 29, the arc-shaped plate 32 can be driven to move. The limiting ball 34 can contact the end of the bucket lid and provide support. And since the positioning block 26 is always located in the middle position between the sliding member 10 and the rotating shaft 4, the fixing rod 29 is also always located in the middle position between the sliding member 10 and the rotating shaft 4. The center line of the arc-shaped plate 32 will always be consistent with the center line of the bucket lid. Since the sleeves 33 and the limiting balls 34 are arranged in a circular pattern, the limiting balls 34 will be distributed in a circular pattern with the center line of the bucket lid as the axis. The support points at the end of the bucket lid are also distributed in a circular pattern, improving the stability of the support for the bucket lid. When the bucket lid rotates, the limiting balls 34 will also rotate correspondingly, reducing the resistance during the rotation of the bucket lid. A plurality of telescopic rods 36 are fixedly installed on one side of the fixing plate 35. The telescopic rods 36 are arranged in a circular pattern. And a push plate 37 is fixedly installed at the end of the telescopic rods 36. A bearing 38 is fixedly installed at the center of the push plate 37.A fixed shaft 39 is fixedly installed on the inner wall of the bearing 38. One end of the fixed shaft 39 is fixedly installed with a rotating plate 40 for limiting the barrel body. By adjusting the position of the fixed rod 29, the fixed plate 35 can also be driven to move, so that the fixed plate 35 drives the push plate 37 and the rotating plate 40 to move towards the end of the barrel body, and the telescopic rod 36 is compressed. The elastic force of the telescopic rod 36 causes the rotating plate 40 to push the barrel body towards the barrel cover. Since the limiting ball 34 provides stable support for the barrel cover, the barrel cover and the barrel body will always remain in close contact, improving the stability of the connection between the barrel cover and the barrel body during welding. When the barrel body rotates, since the rotating plate 40 is in close contact with the end of the barrel body, the rotating plate 40 will drive the fixed shaft 39 to rotate synchronously. The bearing 38 can reduce the friction when the rotating plate 40 rotates. And since the fixed rod 29 is always located at the middle position between the sliding member 10 and the rotating shaft 4, the central axes of the fixed plate 35, the push plate 37 and the rotating plate 40 will always be consistent with the central axis of the barrel body. There will be no relative sliding between the barrel body and the rotating plate 40 during the rotation process, improving the stability of the barrel body during the rotation process.,
[0031] A rotating rod 5 is rotatably installed between two supports 3. Two cleaning rollers 8 for cleaning the barrel cover and the barrel body are fixedly installed on the rotating rod 5. The rotation direction of the cleaning roller 8 is the same as the rotation directions of the barrel cover and the barrel body. A first gear 6 is fixedly installed on the rotating shaft 4. A second gear 7 meshing with the first gear 6 is fixedly installed on the rotating rod 5. The diameter of the second gear 7 is smaller than that of the first gear 6. When the rotating shaft 4 rotates, it will drive the first gear 6 to rotate forward. Through the meshing of the first gear 6 and the second gear 7, the second gear 7, the rotating rod 5 and the cleaning roller 8 will be driven to rotate in the reverse direction. Since the rotating shaft 4 drives the elastic belt 21 and the roller 16 to rotate forward, the barrel body and the barrel cover will rotate in the reverse direction. The rotation direction of the cleaning roller 8 is the same as that of the barrel body and the barrel cover, which can effectively clean the surfaces of the barrel body and the barrel cover. And since the diameter of the second gear 7 is smaller than that of the first gear 6, the rotation speed of the cleaning roller 8 will be faster than that of the barrel body and the barrel cover, improving the cleaning efficiency. Sufficient frictional force can be generated between the barrel body and the elastic belt 21 and between the roller 16 and the barrel cover, reducing the situation of the barrel body and the barrel cover slipping and improving the rotation consistency of the barrel body and the barrel cover.
[0032] Specifically, first, adjust the distance between the sliding member 10 and the rotating shaft according to the diameter of the welded air barrel. Rotate the adjusting rod 12. Through the cooperation of the threaded strip 13 at its end with the limiting seat 14 and the limitation of the guiding strip 9 on the sliding member 10, the adjusting rod 12 drives the connecting rod 11 and the two sliding members 10 to slide synchronously along the guiding strip 9. And due to the self-locking property of the thread, prevent the sliding member 10 from sliding during welding. Then, place the barrel body between the two rollers 16, and place the barrel cover on the two elastic bands 21. The gravity of the barrel cover will cause the elastic bands 21 to deform, and the two fixing rings 17 will press against the lower end of the barrel cover. At the same time, the two annular plates 19 will press against the arc surface of the barrel cover. And according to the different arcs of the barrel cover, the annular plate 19 will be pushed by the arc surface of the barrel cover, and the first spring 20 will be stretched. After the elastic band 21 deforms, it can closely adhere to the arc surface of the barrel cover, providing sufficient support for the barrel cover. After the motor 2 starts, it will drive the rotating shaft 4 to rotate. The rotating shaft 4 will drive the upper roller 16 on it to rotate. Through the friction between the roller 16 and the barrel body, the barrel body will be driven to rotate, and drive the roller 16 and the roller shaft 15 on the corresponding sliding member 10 to rotate. At the same time, the rotating shaft 4 will also drive the fixing ring 17 on it to rotate. Through the limitation of the limiting strip 22 on the sliding ring 18, the sliding ring 18 and the fixing ring 17 will be driven to rotate synchronously. The elastic band 21 will also rotate synchronously. Through the friction between the elastic band 21 and the barrel cover, the barrel cover will be driven to rotate. And through the support of the fixing ring 17 and the sliding ring 18 for the barrel cover, the stability of the barrel cover during rotation is improved. When the adjusting rod 12 drives the two sliding members 10 to slide, the sliding member 10 will also drive the slider 24 to slide synchronously in the slide rail 23. Since the second springs 25 are installed on both sides of the positioning block 26, the two second springs 25 on both sides will always be in the same compressed or stretched state. When the slider 24 slides, the elastic forces of the two second springs 25 on both sides will push the positioning block 26 to move, so that the positioning block 26 is always in the middle position between the slider 24 and the corresponding inner wall of the slide rail 23. And through the cooperation of the ball 41 and the chute 42, the friction between the slider 24 and the positioning block 26 during sliding can be reduced, improving the accuracy of the sliding position of the positioning block 26. When the positioning block 26 moves, it will drive the device box 27 to move synchronously. When rotating the screw 30, through the cooperation of the limiting ring 28 and the screw 30 and the guiding of the limiting groove 31 on the fixed rod 29, the fixed rod 29 will be controlled to drive the limiting ring 28 to slide in the device box 27. By adjusting the position of the fixed rod 29, the arc-shaped plate 32 can be driven to move. The limiting ball 34 can contact the end of the barrel cover and provide support. And since the positioning block 26 is always located in the middle position between the sliding member 10 and the rotating shaft 4, and the fixed rod 29 is also always located in the middle position between the sliding member 10 and the rotating shaft 4, the center line of the arc-shaped plate 32 will always be consistent with the center line of the barrel cover. Since the sleeves 33 and the limiting balls 34 are arranged in a circular pattern, the limiting balls 34 will be distributed in a circular pattern with the center line of the barrel cover as the axis. The support points at the end of the barrel cover are also distributed in a circular pattern, improving the stability of the support for the barrel cover. When the barrel cover rotates,The limiting ball 34 will also rotate correspondingly, reducing the resistance during the rotation of the barrel cover. By adjusting the position of the fixed rod 29, the fixed plate 35 can also be driven to move, causing the fixed plate 35 to drive the push plate 37 and the rotating plate 40 to move towards the end of the barrel body, and compressing the telescopic rod 36. The elastic force of the telescopic rod 36 causes the rotating plate 40 to push the barrel body towards the barrel cover. Since the limiting ball 34 provides stable support for the barrel cover, the barrel cover and the barrel body will always remain in close contact, improving the stability of the connection between the barrel cover and the barrel body during welding. When the barrel body rotates, since the rotating plate 40 is in close contact with the end of the barrel body, the rotating plate 40 will drive the fixed shaft 39 to rotate synchronously. The bearing 38 can reduce the friction during the rotation of the rotating plate 40. And since the fixed rod 29 is always located at the middle position between the sliding member 10 and the rotating shaft 4, the central axes of the fixed plate 35, the push plate 37, and the rotating plate 40 will always be aligned with the central axis of the barrel body. There will be no relative sliding between the barrel body and the rotating plate 40 during the rotation process, improving the stability during the rotation of the barrel body. When the rotating shaft 4 rotates, it will drive the first gear 6 to rotate forward. Through the meshing of the first gear 6 and the second gear 7, the second gear 7, the rotating rod 5, and the cleaning roller 8 will be driven to rotate in the reverse direction. Since the rotating shaft 4 drives the elastic belt 21 and the roller 16 to rotate forward, the barrel body and the barrel cover will rotate in the reverse direction. The cleaning roller 8 rotates in the same direction as the barrel body and the barrel cover, which can effectively clean the surfaces of the barrel body and the barrel cover. And since the diameter of the second gear 7 is smaller than that of the first gear 6, the rotating speed of the cleaning roller 8 will be faster than that of the barrel body and the barrel cover, improving the cleaning efficiency. Sufficient friction is generated between the barrel body and the elastic belt 21 and between the roller 16 and the barrel cover, reducing the slipping of the barrel body and the barrel cover and improving the consistency of the rotation of the barrel body and the barrel cover.
