Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an external coil welding device that can be quickly positioned. Background Technology

[0002] An external coil is a type of pipe in which heating elements are wound around the outer wall of a container, indirectly heating the internal medium through the container wall. Its working principle is to transfer heat through the container wall, avoiding direct contact between the heating elements and the medium, thus reducing corrosion and scaling problems. An external coil typically consists of a coil, support frame, insulation layer, and outer shell. The coil is the core component of the external coil, and its material is usually stainless steel or aluminum because these materials are corrosion-resistant, high-temperature resistant, and rust-resistant. While the heating speed is slower, the external coil effectively avoids direct corrosion and scaling problems caused by the medium on the heating elements. External coils are widely used in applications with high requirements for water quality or the medium itself, such as reaction vessels in the pharmaceutical industry and fermentation tanks in the food industry.

[0003] Currently, traditional welding equipment used for external coil pipes typically guides and bends the pipe to be welded using a set of guide wheels. Then, workers attach the pipe to the outer wall of the container and weld it using a welding structure, while simultaneously rotating the container. However, this method makes the pipe prone to displacement, affecting the welding effect and precision, and consequently, the product quality. Traditional equipment also lacks a structure to assist in positioning the pipe during welding, making it inconvenient to use and relatively impractical. Utility Model Content

[0004] The purpose of this invention is to provide a fast-positioning external coil welding device to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapidly positioning external coil welding device, comprising a welding apparatus, two linear modules on one side of the welding apparatus, a base connected above the two linear modules, symmetrical adjustment grooves on the top of the base, and a lead screw rotatably mounted in the adjustment groove, with one end of the lead screw connected to a motor outside the base, and movably connected mounting brackets fitted symmetrically on the outer side of the lead screw, with rollers rotatably mounted on the upper end of the mounting brackets, a vertical pole on the side of the linear module away from the welding apparatus, and several guide positioning mechanisms arranged vertically on one side of the vertical pole, with guide components on the opposite outer sides of the two linear modules on the base side, each guide positioning mechanism including a telescopic rod, the telescopic rod being fixedly mounted on one side of the vertical pole, and a guide seat being fixedly connected to the telescopic end of the telescopic rod.

[0006] Furthermore, the guiding and positioning mechanism also includes a limiting plate, which is symmetrically arranged on one side of the guide seat. One end of the limiting plate is sleeved on the outside of the guide seat. Several guide wheels are rotatably embedded in the end of the guide seat away from the telescopic rod. Several guide wheels are rotatably embedded in the inner walls of the limiting plate. A cavity is opened inside one side of the guide seat, and a gear is rotatably installed in the cavity. A drive rod is symmetrically arranged on the outside of the gear, and several tooth grooves that mesh with the gear are opened on the side wall of the drive rod near the gear. Both sides of one end of the drive rod are connected to the limiting plate through fixing blocks. A telescopic rod is provided at one end of the guide seat, and the telescopic end of the telescopic rod is fixedly connected to one end of the drive rod on one side. The guiding and positioning mechanism is designed as follows: The telescopic rod can be adjusted to change its extension length, thereby adjusting the position of the guide seat for bending and guiding the pipe. The telescopic rod can also drive two limiting plates to clamp and limit the pipe, allowing for quick positioning, fixing, and guiding of the welded pipe. The uppermost guiding and positioning mechanism pushes the pipe tightly against the outer wall of the container, enabling welding. This design is convenient, facilitating pipe guidance and positioning, preventing displacement during welding that could affect welding accuracy and quality, and is adaptable to pipes of different diameters, making it more practical. The drive rod has an L-shaped structure, and both guide wheels one and two have rubber sleeves on their outer walls to protect the welded pipe from scratches.

[0007] Furthermore, the guide assembly includes two support plates. The lower end of each support plate is fixedly connected to the linear module. A guide roller 1 is rotatably installed between the two support plates. A guide roller 2 is located above the guide roller 1. A telescopic rod 3 is provided on the opposite outer side of each support plate. The telescopic end of the telescopic rod 3 is rotatably connected to one end of the guide roller 2. The guide assembly can be adapted to guide pipes of different diameters.

[0008] Furthermore, the upper and lower walls of the guide seat are provided with sliding grooves that communicate with the cavity, and the sliding grooves are adapted to the fixing blocks. The limiting plate has a U-shaped structure, and the two fixing blocks are respectively fixedly connected to the inner wall of the opening end of the fixing block to limit and guide the fixing block.

[0009] Furthermore, the lead screw is a bidirectional lead screw, and one or both sets of the two sets of rollers are connected to a servo motor, which can synchronously drive the two mounting brackets to move towards the opposite inner or outer side.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model, through a guiding and positioning mechanism, can adjust the position of several guide seats to match the curvature of the container to be welded, thereby guiding the pipe to be welded. At the same time, the telescopic rod drives the drive rod, which in turn drives the gear, thereby driving the two limiting plates to move inward relative to each other. The limiting plates clamp, limit, and guide the pipe, and the uppermost guiding and positioning mechanism pushes the pipe to fit against the outside of the container, thus enabling welding. This allows for quick positioning and guidance of the pipe, ensuring a tight fit with the container and preventing deviation that could affect welding accuracy. It can also be used with pipes of different specifications, making it widely applicable and more practical.

[0012] 2. The position of the mounting bracket can be adjusted to accommodate containers of different lengths, ensuring stable support. The guide component can guide the pipe and is compatible with pipes of different diameters. Attached Figure Description

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.

[0020] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution: a rapidly positioning external coil welding device, including a welding device 1. Two linear modules 2 are provided on one side of the welding device 1. In this example, the welding device 1 includes a structure for horizontal and vertical adjustment and is equipped with a robotic arm for orientation-based welding. The welding device 1 is existing technology and only requires a structure for adjusting its XYZ three-axis position in conjunction with the welding structure; therefore, it is not described in detail in this example. A base 3 is connected above the two linear modules 2. In this example, the linear modules 2 are existing technology, so they are not described in detail. The top of the base 3 is symmetrical. An adjustment groove is provided, and a lead screw 17 is rotatably installed in the adjustment groove. One end of the lead screw 17 is connected to a motor 18 outside the base 3. A movable mounting bracket 4 is fitted on the symmetrical position outside the lead screw 17, and a roller 5 is rotatably installed on the upper end of the mounting bracket 4. A vertical pole 6 is provided on the side of the linear module 2 away from the welding device 1. Several guide positioning mechanisms 7 are arranged vertically on one side of the vertical pole 6. Guide components are provided on the opposite outer side of the two linear modules 2 on the side of the base 3. The guide positioning mechanism 7 includes a telescopic rod 8, which is fixedly installed on one side of the vertical pole 6. A guide seat 9 is fixedly connected to the telescopic end of the telescopic rod 8. In this example, the guide positioning mechanism 7 also includes a limiting plate 10, which is symmetrically arranged on one side of the guide seat 9. One end of the limiting plate 10 is sleeved on the outside of the guide seat 9. Several guide wheels 11 are rotatably installed on the end of the guide seat 9 away from the telescopic rod 8. Several guide wheels 22 are rotatably installed on the opposite inner walls of the limiting plate 10. A cavity 23 is opened inside one side of the guide seat 9. A gear 13 is rotatably installed in the cavity 23. A drive rod 14 is symmetrically arranged on the outside of the gear 13. Several tooth grooves that mesh with the gear 13 are opened on the side wall of the drive rod 14 near the gear 13. Both sides of one end of the drive rod 14 are connected to the limiting plate 10 through fixing blocks 16. One end of the guide seat 9 is provided with a telescopic rod 11. 5. The telescopic end of the telescopic rod 15 is fixedly connected to one end of the drive rod 14 on one side. The guide positioning mechanism 7 allows adjustment of the telescopic length of the telescopic rod 8 to adjust the position of the guide seat 9, facilitating the bending and guiding of the pipe. The telescopic rod 15 can also drive the two limiting plates 10 to clamp and limit the pipe, enabling quick positioning, fixing, and guiding of the welded pipe. The uppermost guide positioning mechanism 7 pushes the pipe tightly against the outer wall of the container, allowing welding to be performed using the welding device 1. This is convenient to use, facilitates pipe guidance and positioning, avoids displacement during welding affecting welding accuracy and quality, and is adaptable to pipes of different diameters, making it more practical. In this example, the upper and lower walls of the guide seat 9 are provided with grooves 24 communicating with the chamber 23, and the grooves 24 are adapted to the fixing block 16. The limiting plate 10 has a U-shaped structure, and the two fixing blocks 16 are fixedly connected to the inner wall of the opening end of the fixing block 16 to limit and guide the fixing block 16.In this example, the drive rod 14 has an L-shaped structure, and the outer walls of both the first guide wheel 11 and the second guide wheel 12 are fitted with rubber sleeves to protect the welded pipe and prevent it from being scratched.

[0021] In this example, the guide assembly includes two support plates 19. The lower end of each support plate 19 is fixedly connected to the linear module 2. A guide roller 20 is rotatably mounted between the two support plates 19. A guide roller 21 is located above the guide roller 20. Telescopic rods 22 are provided on opposite outer sides of each support plate 19, and the telescopic ends of the telescopic rods 22 are rotatably connected to one end of the guide roller 21. This guide assembly can be adapted to guide pipes of different diameters. In this example, the lead screw 17 is a bidirectional lead screw. One or both sets of rollers 5 are connected to a servo motor. The servo motor can control the forward and reverse rotation of the rollers 5 and can control their speed, synchronously driving the two mounting brackets 4 to move towards the opposite inner or outer sides.

[0022] The working principle of this utility model is as follows: In use, the motor 18 drives the lead screw 17 to rotate, thereby adjusting the position of the mounting bracket 4 to fit the container for welding the coil. The container is then placed on the roller 5. The telescopic rod 22 then extends and retracts to adjust the vertical movement of the guide roller 21, changing the distance between guide roller 21 and guide roller 20 to fit the coil pipe to be welded, thus guiding the pipe. Several guide positioning mechanisms 7 are then adjusted as needed to adjust the position of several guide seats 9, allowing the pipe to pass between the two limiting plates 10. Simultaneously, the telescopic rod 15 is activated, pushing the connected drive rod 14. The teeth on the drive rod 14 drive the meshing gear 13 to rotate, thereby driving another drive rod 14, causing the two drive rods 14 to move synchronously towards each other. The inner side moves, causing the drive rod 14 to drive the fixed block 16, which in turn drives the connected limiting plate 10 to move synchronously until the limiting plate 10 clamps and positions the pipe. Multiple guide positioning mechanisms 7 push the pipe to different positions, allowing it to be guided, positioned, and bent to match the curvature of the container. The guide seat 9 in the uppermost guide positioning mechanism 7 pushes the pipe to fit tightly against the container wall. Then, the pipe can be welded to the container using the welding device 1. At the same time, the base 3 is moved by adjusting the linear module 2, so that the pipe of the coil is wrapped around the outside of the container. This device can quickly position and guide the pipe of the coil, assisting it to fit against the container for welding, avoiding deviation that affects welding accuracy or quality. It can also be used for welding pipes of different sizes of external coils, making it convenient to use and more practical.
