Description

Technical Field

[0001] This utility model relates to the field of copper tube processing technology, and in particular to a 360-degree automatic copper tube feeding and welding device. Background Technology

[0002] In the field of copper tube processing, welding the ends of copper tubes is a common process. In particular, some applications require 360° circumferential spot welding of the copper tube ends to ensure weld sealing and structural strength. Currently, most copper tube welding equipment lacks a stable 360° rotation drive structure and often relies on manual rotation of the copper tube to adjust the welding position. This not only makes it difficult to ensure the coaxiality and stability of the copper tube during rotation, resulting in uneven weld point distribution, large fluctuations in welding quality, and a significant increase in manual labor intensity, but also leads to low efficiency. On the other hand, the few pieces of equipment with rotation function have poor coordination between the rotation mechanism and the spot welding gun. During rotation, copper tube displacement and jamming are prone to occur, making it impossible to accurately connect the spot welding station. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model proposes an automatic copper tube feeding and 360-degree welding device.

[0004] This utility model proposes an automatic copper tube feeding and 360-degree welding device, including a cabinet. A gantry and a fine-tuning platform are mounted on the top of the cabinet. A spot welding gun is mounted on the top of the fine-tuning platform. A rotary drive module is mounted on the top of both the cabinet and the gantry. The rotary drive module includes a first lifting drive cylinder mounted on the top of the gantry and a bracket mounted on the top of the cabinet. A lifting seat is mounted on the drive end of the first lifting drive cylinder, and a rotary drive cylinder is mounted on the bottom end of the lifting seat. A pressure roller is mounted on the drive end of the rotary drive cylinder. Support rollers are symmetrically rotated and connected to the top of the bracket. Copper tubes are placed between the support rollers. After the pressure rollers descend to their positions, their edges align with the edges of the support rollers. Relying on the friction between the support rollers and the copper tubes, the copper tubes are rotated 360° to perform spot welding at multiple locations on the ends of the copper tubes.

[0005] Furthermore, a second lifting cylinder is installed on the side of the lifting seat, and a protective cover is installed on the telescopic end of the second lifting cylinder. An opening is opened at the bottom of the protective cover to avoid the spot welding gun head after the protective cover is lowered into place.

[0006] Furthermore, a feeding module is installed at the top of the equipment cabinet to sequentially transport several copper pipes between the idler rollers.

[0007] Furthermore, the feeding module includes a horizontal drive cylinder installed at the top of the equipment cabinet. The telescopic end of the horizontal drive cylinder is connected to a vertical drive cylinder via a base plate. The telescopic end of the vertical drive cylinder is connected to a beam frame plate. Both ends of the beam frame plate are connected to feeding plates.

[0008] Furthermore, the feeding module also includes several support plates installed on the top of the equipment cabinet, each support plate having a receiving plate installed on its top, and the receiving plates being located between the feeding plates.

[0009] Furthermore, each feeding plate and receiving plate has several grooves at equal intervals at its top to accommodate copper tubes, and the grooves on the feeding plate and the receiving plate are on the same straight line.

[0010] The beneficial effects of this utility model are as follows: A rotary drive module, installed together on the top of the equipment cabinet and the gantry frame, uses a first lifting drive cylinder to lower the pressure roller and bring it into contact with the support roller. The rotary drive cylinder then drives the pressure roller to rotate, and the friction between the support roller and the copper tube causes the copper tube to rotate stably 360° without manual adjustment. Simultaneously, the precise adjustment of the spot welding gun position using a fine-tuning platform ensures a good match between the rotating mechanism and the spot welding gun, effectively preventing displacement and jamming during copper tube rotation. This guarantees the coaxiality and stability of the copper tube rotation, ensuring uniform distribution of weld points and stable welding quality. It reduces manual labor intensity and improves welding efficiency, meeting the requirements for 360° circumferential spot welding of the copper tube ends. Attached Figure Description

[0013] Reference Figure 1-5 This utility model proposes an automatic copper tube feeding 360-degree welding equipment, including an equipment cabinet 1. A gantry frame 2 and a fine-tuning platform 3 are installed on the top of the equipment cabinet 1. A spot welding gun 4 is installed on the top of the fine-tuning platform 3. The fine-tuning platform 3 can make fine adjustments to the spatial position of the LP-180 model spot welding gun 4 through manual or automatic adjustment, including fine-tuning of displacement in the front-back, left-right and up-down directions. This ensures that the spot welding gun head of the spot welding gun 4 can be accurately aligned with the end of the copper tube 7 to be welded, meeting the requirements of different specifications of copper tubes 7 or different welding processes for the position of the weld point. It should be noted that the specific structure and working principle of the fine-tuning platform 3 and the spot welding gun 4 are technical contents well known to those skilled in the art, and will not be described in detail here. The top of the equipment cabinet 1 and the gantry 2 are jointly equipped with a rotary drive module 6. The rotary drive module 6 consists of a first lifting drive cylinder 61, a bracket 62, a lifting seat 63, a rotary drive cylinder 64, a pressure roller 65, and a support roller 66. The first lifting drive cylinder 61 is fixedly installed on the top of the gantry 2, with its drive end pointing vertically downward and connected to the lifting seat 63, which can drive the lifting seat 63 to move up and down. The bracket 62 is fixedly installed on the top of the equipment cabinet 1, located at the corresponding work position of the spot welding gun 4. The top of the bracket 62 is symmetrically connected to two support rollers 66 through bearings. The two support rollers 66 form a support space for placing the copper pipe 7. When the copper pipe 7 is placed on the support roller 66, it can move synchronously with the rotation of the support roller 66. The bottom of the lifting seat 63 is equipped with a rotary drive cylinder 64. The drive end of 64 is connected to the pressure roller 65, which can drive the pressure roller 65 to rotate around its own axis. When the copper tube 7 needs to be welded, the first lifting drive cylinder 61 first drives the lifting seat 63 to move downward, which drives the pressure roller 65 to descend synchronously until the pressure roller 65 is in place. At this time, the edge of the pressure roller 65 is in close contact with the edge of the support roller 66. At the same time, the pressure roller 65 generates a certain clamping force on the copper tube 7, so that the copper tube 7 is stably clamped between the pressure roller 65 and the support roller 66. Then, the rotation drive cylinder 64 drives the pressure roller 65 to rotate. The pressure roller 65 drives the support roller 66 to rotate through the friction between the pressure roller 65 and the support roller 66. The support roller 66 then drives the copper tube 7 to rotate 360 ​​degrees around its own axis through the friction between the support roller 66 and the copper tube 7. During this process, the spot welding gun 4 can perform continuous spot welding on multiple circumferential positions at the end of the copper tube 7 to ensure the uniformity and integrity of the welding. To improve the safety of the welding process and avoid safety hazards caused by welding sparks, a second lifting cylinder 67 is installed on the side of the lifting base 63. The telescopic end of the second lifting cylinder 67 is vertically downward and connected to the protective cover 68. The protective cover 68 is made of high-temperature resistant and anti-spark metal material. Its bottom end has an opening 69 that is compatible with the spot welding gun head of the spot welding gun 4. When the equipment enters the welding operation state, the second lifting cylinder 67 drives the protective cover 68 to move downward until the protective cover 68 is lowered into place. At this time, the protective cover 68 covers the welding area of ​​the copper tube 7, and only avoids the spot welding gun head of the spot welding gun 4 through the opening 69 at the bottom end, so that the spot welding gun head can normally contact the welding part. At the same time, it effectively blocks the welding sparks from splashing to the surrounding area, ensuring the safety of the operators around the equipment and preventing other parts from being damaged by sparks. A feeding module 5 is also installed at the top of the equipment cabinet 1 to automatically feed copper pipes 7. It sequentially and orderly conveys several copper pipes 7 to be welded to the welding station between the rollers 66, replacing manual feeding and improving the automation level and production efficiency of the equipment. The feeding module 5 consists of a horizontal drive cylinder 51, a support plate 52, a vertical drive cylinder 53, a beam frame plate 54, a feeding plate 55, and a receiving plate 56. The horizontal drive cylinder 51 is fixedly installed at the top of the equipment cabinet 1, and its telescopic end is connected to the vertical drive cylinder 53 through a base plate, which can drive the vertical drive cylinder 53 to move laterally along the length of the equipment cabinet 1. The telescopic end of the vertical drive cylinder 53 is connected to the beam frame plate 54, which can drive the beam frame plate 54 to move vertically up and down. Each end of the beam frame plate 54 is connected to a feeding plate 55. The material plates 55 are symmetrically distributed. At the same time, several spaced support plates 52 are installed at the top of the equipment cabinet 1. Each support plate 52 is fixedly installed with a receiving plate 56 at its top. The receiving plates 56 are located between two feeding plates 55, forming a cooperative feeding structure. To ensure the stability of the copper tube 7 during the conveying process, several semi-circular grooves 57 are equally spaced along the length direction at the top of each feeding plate 55 and receiving plate 56. The diameter of the grooves 57 is adapted to the outer diameter of the copper tube 7 to be conveyed, and is used to accommodate and limit the copper tube 7 to prevent the copper tube 7 from rolling off during the conveying process. In addition, the grooves 57 on the feeding plate 55 and the grooves 57 on the receiving plate 56 are aligned in a straight line on the same horizontal plane to ensure that the copper tube 7 can be smoothly transferred between the feeding plate 55 and the receiving plate 56. The specific feeding process of the feeding module 5 is as follows: In the initial state, the feeding plate 55 is located below the receiving plate 56. The operator or the upstream feeding mechanism first places several copper pipes 7 into the grooves 57 of the receiving plate 56 to complete the material preparation. When the welding station between the rollers 66 needs to be fed, the vertical drive cylinder 53 first drives the beam frame plate 54 to move upward, driving the feeding plate 55 to rise synchronously. During the rising process of the feeding plate 55, the groove 57 at its top gradually lifts the copper pipes 7 in the grooves 57 of the receiving plate 56 until the copper pipes 7 are completely separated from the receiving plate 56 and stably supported in the grooves 57 of the feeding plate 55. Then the horizontal drive cylinder 51 drives the vertical drive cylinder 53, the beam frame plate 54 and the feeding plate 55 to rise. The feeding plate 55 moves laterally towards the welding station where the idler roller 66 is located. When the feeding plate 55 moves above the idler roller 66 and the groove 57 on the feeding plate 55 is aligned with the support space between the idler roller 66, the lateral drive cylinder 51 stops. Then, the vertical drive cylinder 53 drives the beam frame plate 54 and the feeding plate 55 to move downward, and the copper tube 7 on the feeding plate 55 descends accordingly until the copper tube 7 is placed stably between the idler rollers 66, completing one automatic feeding cycle. Finally, the vertical drive cylinder 53 drives the feeding plate 55 to rise and reset, and the lateral drive cylinder 51 drives the feeding plate 55 to move laterally back to the initial preparation position, ready for the next feeding operation, thereby realizing the continuous automatic feeding of the copper tube 7.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
