Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more specifically to a side welding device for a dryer filter. Background Technology

[0002] As a key component in the refrigeration system field, most dryer filters only have an inlet and an outlet at both ends for refrigerant to pass through. However, some dryer filters have a small tube on the side for connecting to pressure monitoring equipment or as a cleaning tube for the dryer filter. The small tube is usually connected to the cylinder by welding, and the quality of the side welding directly affects the sealing performance and service life.

[0003] Traditional welding methods rely on manual operation. During manual welding, the positioning of the cylinder and pipe fittings depends on experience, which can easily lead to welding misalignment, resulting in uneven weld strength or defects such as porosity and slag inclusions. Although some welding processes use tooling to clamp the two pipe fittings for welding, the tooling needs to be manually rotated or welded around it during the welding process. Furthermore, the installation and removal of pipe fittings before and after welding are relatively troublesome, the entire welding process is time-consuming, has a low degree of automation, and limits production efficiency. Summary of the Invention

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] Figures 1 to 10 The image shows an embodiment of the present invention.

[0030] Example:

[0031] A side welding device for a dryer filter includes a base 1. A rotating disk 2 driven by a first motor is provided on the upper side of the base 1. A first clamping part 3 and a second clamping part 4 are arranged opposite each other on the upper side of the rotating disk 2. A first positioning hole 5 penetrating both sides is provided in the first clamping part 3. A second positioning hole 6 aligned with the first positioning hole 5 is provided in the second positioning hole 6. A fixing component for fixing a main pipe component 80 is provided in the second positioning hole 6. A first feeding part 7 for conveying the main pipe component 80 toward the first positioning hole 5 is provided on the side of the base 1. A second feeding part 8 for conveying a side pipe component 81 is provided above the base 1 at a position corresponding to the first clamping part 3 and the second clamping part 4. A first correcting component for correcting the position of the main pipe component 80 is provided in the first clamping part 3. A second correcting component for correcting the position of the side pipe component 81 is provided at the lower end of the second feeding part 8. A welding machine assembly 9 for welding the main pipe component 80 and the side pipe component 81 is provided on the side of the base 1. In this invention, during welding, the main pipe component 80 is fed towards the first clamping part 3 via the first feeding part 7, and the side pipe component 81 is fed towards the second clamping part 4 via the second feeding part 8. After feeding, the first straightening component of the first clamping part 3 corrects the posture of the main pipe component 80, aligning the welding joint on the main pipe component 80 with the side pipe component 81. Similarly, the second straightening component at the lower end of the second feeding part 8 corrects the posture of the side pipe component 81, aligning the welding joint of the side pipe component 81 with the welding joint of the main pipe component 80 for splicing. After splicing, a welding machine assembly welds the spliced ​​joint. During welding, the rotating disk 2 drives the main pipe component 80 and the side pipe component 81 to rotate, enabling the welding machine assembly to uniformly and completely weld the joint, ensuring welding quality. This application enables automated welding, guaranteeing both welding efficiency and quality each time, thus solving the problems of low automation and limited production efficiency in existing manual welding methods.

[0032] The first clamping part 3 is mounted on the upper side of the rotating disk 2 via the first adjusting block 10. The top of the first adjusting block 10 is equipped with a first guide rail 11, and a first slider 12 is slidably arranged on the first guide rail 11. The first clamping part 3 is mounted on the upper side of the first slider 12, and the first slider 12 is driven by the first electric push rod 13. The second clamping part 4 is mounted on the upper side of the rotating disk 2 via the second adjusting block 14. The top of the second adjusting block 14 is equipped with a second guide rail 15, and a second slider 16 is slidably arranged on the second guide rail 15. The second clamping part 4 is mounted on the upper side of the second slider 16, and the second slider 16 is driven by the second electric push rod 17. With the aid of the first adjusting block 10 and the second adjusting block 14, when the main pipe component 80 is conveyed by the first feeding section 7, the first motor adjusts the rotating disk 2 to align the first clamping part 3 with the first feeding section 7, and the first electric push rod 13 drives the first clamping part 3 to move closer to and fit against the first feeding section 7, so that the main pipe component 80 in the first feeding section 7 can enter the first clamping part 3. When the main pipe component 80 enters the first clamping part 3, it is corrected by the first straightening component, and the first electric push rod 13 moves the first clamping part 3 closer to the first feeding section 7. The second clamping part 4 moves toward the second clamping part 4, and at the same time, the second electric push rod 17 drives the second clamping part 4 to move toward the first clamping part 3, so that the second clamping part 4 is close to the first clamping part 3. After the first straightening component completes the correction, the main pipe part 80 is fixed by the fixing component of the second clamping part 4. After the main pipe part 80 is fixed by the second clamping part 4, the second electric push rod 17 drives the second clamping part 4 to move in the opposite direction, so that the welding joint of the main pipe part 80 is placed at the axis of the rotating disk 2 and aligned with the side pipe part 81, so as to facilitate subsequent welding.

[0033] The first correction assembly includes a first positioning tube 18, a first drive wheel 19, a mounting plate 20, a second motor 21, a pin tube 22, a positioning pin 23, a first electric telescopic rod 24, and a second electric telescopic rod 25. The first positioning tube 18 is disposed within the first clamping part 3, and a first positioning hole 5 is placed within the first positioning tube 18. A correction cavity 26 is disposed within the first clamping part 3. A first connecting hole 27 communicating with the correction cavity 26 is disposed on the side of the first positioning tube 18. A third guide rail 28 aligned with the first connecting hole 27 is disposed within the correction cavity 26. A third slider 29 is slidably disposed on the third guide rail 28. The mounting plate 20 is disposed above the third slider 29. The second motor 21 is mounted on the upper side of the mounting plate 20. A first gear 30 is mounted on the output shaft of the second motor 21, located on the side of the second motor 21 facing the pin tube 22. A first rotating shaft 31 parallel to the pin tube 22 is provided. A second gear and a first drive wheel 19 are sleeved on the first rotating shaft 31. The first gear 30 and the second gear are meshed and connected. A first electric telescopic rod 24 is installed on the side of the mounting plate 20 away from the pin tube 22. A mounting hole 32 is provided on the side of the mounting plate 20 away from the pin tube 22. The output shaft of the first electric telescopic rod 24 abuts against the bottom of the mounting hole 32 through a first spring 33. A second through hole 34 communicating with the pin tube 22 is provided on the upper side of the first clamping part 3. The pin tube 22 is vertically installed in the second through hole 34. The second electric telescopic rod 25 is vertically installed in the upper part of the pin tube 22. The output shaft of the second electric telescopic rod 25 is connected to the upper end of the positioning pin 23 through the second spring 35. The lower end of the positioning pin 23 is hemispherical. During correction, the second electric push rod 17 drives the positioning pin 23 to conform to the outer wall of the main pipe component 80 through the second through hole 34. Then, the first electric push rod 13 drives the mounting plate 20 to move towards the main pipe component 80, causing the first drive wheel 19 to conform to the outer wall of the main pipe component 80. The second motor 21 drives the first drive wheel 19 and the main pipe component 80 to rotate. When the weld joint on the main pipe component 80 moves to align with the positioning pin 23, the lower end of the positioning pin 23 will insert into the weld joint, keeping the weld joint facing upwards in the correct posture. The first spring 33 provides sufficient pressure between the first drive wheel 19 and the surface of the main pipe component 80 to drive the main pipe component 80 to rotate. However, when the positioning pin 23 is inserted into the weld joint, the first drive wheel 19 cannot drive the main pipe component 80 to rotate. By setting the second spring 35, the positioning pin 23 can always conform to the surface of the main pipe component 80, and when the weld joint is aligned with the positioning pin 23, the positioning pin 23 can quickly enter the weld joint. By setting the second electric telescopic rod 25, after the main component 80 is positioned, the main component 80 can be fixed by the second clamping part 4, and then the positioning pin 23 can be separated from the main component 80 by the second electric telescopic rod 25, which facilitates the subsequent welding work.

[0034] The fixing assembly includes a second positioning tube 36, a third electric telescopic rod 37, and a fixing block 38. The second positioning tube 36 is aligned with the first positioning tube 18. The second clamping part 4 is provided with mounting grooves 39 on both sides of the second positioning tube 36. The openings of the two mounting grooves 39 are connected to the second positioning tube 36 through a third through hole 40. The two mounting grooves 39 are each provided with a third electric telescopic rod 37, and the two third electric telescopic rods 37 are arranged opposite each other. The output ends of the two third electric telescopic rods 37 are each provided with a fixing block 38. The fixing block 38 is recessed on the side facing the second positioning tube 36 with a control groove 41. A pressure sensor 42 is installed at the bottom of the control groove 41. A clamping block 43 is slidably arranged in the control groove 41. One end of the clamping block 43 is placed outside the control groove 41, and the other end is connected to the pressure sensor 42 through a third spring 44. After the main component 80 is corrected by the first straightening component, the end of the main component 80 is moved into the second positioning tube 36 by moving the second clamping part 4. Then, the two clamping blocks 43 are moved toward the main component 80 by the two third electric telescopic rods 37 to clamp the main component 80. With the help of the third spring 44 and the pressure sensor 42, the clamping force of the two clamping blocks 43 on the main component 80 can be controlled to avoid damage to the main component 80, while ensuring that the main component 80 will not move during the welding process.

[0035] Each of the two clamping blocks 43 has an arc-shaped plate 45 on one side opposite to the other, and each of the two arc-shaped plates 45 has an adhesive layer on one side opposite to the other. By setting the arc-shaped plate 45 and the adhesive layer, the contact area and friction coefficient with the main pipe component 80 can be increased, thereby facilitating better fixation of the main pipe component 80.

[0036] A ninth electric telescopic rod 70 is installed at the end of the second positioning tube 36 away from the first positioning tube 18. The output shaft of the ninth electric telescopic rod 70 is located inside the second positioning tube 36 and is connected to the second pusher block 71. After welding is completed, the first clamping part 3 and the second clamping part 4 move away from each other, the fixing assembly releases the main component 80, and the welded filter is pushed out and falls down by the ninth electric telescopic rod 70. A guide rod can be set between the first adjusting block 10 and the second adjusting block 14 to guide the fallen filter into the collection frame.

[0037] The second correction assembly includes a fourth electric telescopic rod 46 and a vertically arranged third positioning tube 47. The fourth electric telescopic rod 46 is mounted on the second feeding section 8, and its output shaft is connected to the third positioning tube 47 via a mounting bracket 48. The upper end of the pin tube 22 is aligned with the discharge port 49 of the second feeding section 8. A bearing 50 is arranged around the third positioning tube 47, and the inner ring of the bearing 50 is fixed to the outer wall of the third positioning tube 47. An external gear ring 51 is sleeved on the outer wall. A fourth motor 52 is mounted on the third positioning tube 47 above the bearing 50. The output shaft of the fourth motor 52 faces downward and is connected to a third gear 53. The third gear 53 and the external gear ring 51 are meshed and connected. A fifth electric telescopic rod 55 is installed on the upper part of the third positioning tube 47. The lower end of the output shaft of the fifth electric telescopic rod 55 is positioned below the third positioning tube 47. A sixth electric telescopic rod 64 is installed at the lower end of the fifth electric telescopic rod 55. The output end of the sixth electric telescopic rod 64 faces the third positioning tube 47 and is connected to a centering rod 56. A movable groove 72 is recessed above the bearing 50 on the inner wall of the third positioning tube 47. A fixed plate 73 is installed in the movable groove 72. A movable hole communicating with the outer wall of the third positioning tube 47 is provided at the bottom of the movable groove 72. A tenth electric telescopic rod 74 is installed on the outer wall of the third positioning tube 47. The output shaft of the tenth electric telescopic rod 74 passes through the movable hole into the movable groove 72 and is connected to the fixed plate 73. To ensure a tighter weld between the main pipe component 80 and the side pipe component 81, the weld joint of the side pipe component 81 is machined with a certain arc, concave in the middle and convex on both sides, thus better fitting the weld joint of the main pipe component 80. Therefore, during the splicing process of the side pipe component 81, the weld joint of the side pipe component 81 needs to be adjusted to ensure good alignment with the weld joint of the main pipe component 80. During the correction process, when the side pipe component 81 enters the third positioning tube 47, the fifth electric telescopic rod 55 drives the sixth electric telescopic rod 64 to move down to below the third positioning tube 47, and the sixth electric telescopic rod 64 moves the alignment rod 56 to below the third positioning tube 47. Then, the second feeding part 8 conveys the side pipe component 81 into the third positioning tube 47. After the lower end of the side pipe component 81 contacts the alignment rod 56, the fourth motor 52 drives the external gear ring 51 to rotate. During the rotation of the external gear ring 51, the alignment rod 56 will... As they rotate together, when the adjusting rod 56 engages with the lower recessed part of the side tube 81, it will cause the side tube 81 to rotate as well, thereby adjusting the side tube 81 to the correct posture. After the side tube 81 is adjusted, the fixing plate 73 is brought into contact with the surface of the side tube 81 by the sixth electric telescopic rod 64, so that the side tube 81 is fixed in the third positioning tube 47. At the same time, the adjusting rod 56 is retracted by the sixth electric telescopic rod 64, and the sixth electric telescopic rod 64 is moved upward by the fifth electric telescopic rod 55. This can avoid affecting the welding.

[0038] The first feeding section 7 is provided with a through-hole 57 and a first feeding chute 58 connected to the first feeding hole 57. A seventh electric telescopic rod 68 is provided on the side of the first feeding section 7 away from the base 1. The output shaft of the seventh electric telescopic rod 68 is located inside the first feeding hole 57 and is connected to a first pusher block 60. When the first feeding section 7 conveys the main pipe component 80, the main pipe components 80 arranged on the first feeding chute 58 slide into the first feeding hole 57, and the seventh electric telescopic rod 68 drives the first pusher block 60 to push the main pipe component 80 into the first positioning tube 18, facilitating subsequent correction by the first correction component. After the seventh electric telescopic rod 68 shortens and resets, the next main pipe component 80 automatically slides into the first feeding hole 57 via the first feeding chute 58.

[0039] The second feeding section 8 is provided with a feeding chamber 61. One end of the feeding chamber 61 is connected to the discharge port 49 through a sliding hole 62. The upper end of the sliding hole 62, near the middle of the feeding chamber 61, gradually slopes downward from the upper end to the lower end. The upper end of the sliding hole 62 is wider than the lower end. The lower side of the second feeding section 8 is provided with a pushing hole 63 that is connected to the lower side of the feeding chamber 61 away from the sliding hole 62. The lower side of the second feeding section 8 is vertically installed with an eighth electric telescopic rod 69 at the position of the pushing hole 63. The output shaft of the eighth electric telescopic rod 69 is placed in the pushing hole 63. The second feeding section 8 is provided with a second feeding chute 65 that is connected to the feeding chamber 61. By setting the second feeding chute 65, the side tube 81 can be automatically slid into the feeding chamber 61. The width of the feeding chamber 61 matches the outer diameter of the side tube 81. When the side tube 81 needs to be conveyed, the side tube 81 is lifted away from the sliding hole 62 by the eighth electric telescopic rod 69. During the lifting process, the side tube 81 is placed in the sliding hole 62 and enters the sliding hole 62. As the eighth electric telescopic rod 69 extends, the side tube 81 will gradually enter the sliding hole 62 and then enter the third positioning tube 47 through the discharge port 49.

[0040] The second feeding unit 8 is mounted on top of the base 1 via a support frame 66, and the welding machine assembly 9 is mounted on the side of the base 1 via a robotic arm 67. By setting the first support frame 66, the second feeding unit 8 can be fixed in a suitable position.
