Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a partition welding device and its operating method specifically for circular cylinders. Background Technology

[0002] The structure of adding baffles inside a circular cylinder is frequently seen in mechanical manufacturing. Examples include LNG cylinders, chemical pipelines, and road roller drums in construction machinery. Currently, to ensure the stability of the connection between the baffle and the cylinder, operators need to control a welding device to enter the cylinder and weld the cylinder and baffle together. However, this method presents the following operational problems: 1. Existing welding equipment has a relatively simple structure and function. It cannot achieve synchronous welding on both sides of the partition during welding, resulting in low overall welding efficiency and failing to meet the production needs of enterprises. Examples include: CN202610089114.0, which describes an automatic partition welding machine, and CN201510185883.2, which describes a partition welding device. 2. Currently, when the partitions are inserted into the cylinder, they are mostly placed manually with the assistance of a robotic arm. This method not only increases the overall mechanical structure of the welding equipment, but also takes a long time to install the partitions, affecting subsequent welding operations. 3. The existing welding equipment has a fixed structure, which cannot be adjusted to suit the welding gun and the welded cylinder according to the welding needs during the welding process, resulting in low overall welding flexibility and wasting manpower and resources.

[0003] In summary, existing welding equipment can no longer meet the welding needs of adding baffles inside the cylinder. It is extremely urgent to design and provide a dedicated baffle welding equipment and its operation method for circular cylinders. Summary of the Invention

[0018] Specific Implementation Example 1: As per the appendix to the instruction manual Figure 1 Instruction manual attached Figure 2As shown, existing welding devices for partition 3 and cylinder 4 have a relatively simple structure and function, making it impossible to simultaneously weld both sides of partition 3 during welding, resulting in low overall welding efficiency. Furthermore, the existing partition 3 takes a long time to install into the cylinder 4, affecting subsequent welding operations. Therefore, this invention provides a dedicated partition welding device for circular cylinders. It mainly includes a welding operation mechanism 1 for performing welding operations and a welding auxiliary mechanism 2 for adjusting the rotation and displacement angle of the cylinder 4. The welding operation mechanism 1 includes a vertical frame 11, a lifting and adjusting part 12, a working swing arm 13, a partition feeding component 14, a first welding torch assembly 15, and a second welding torch assembly 16. During installation, the bottom of the vertical frame 11 is installed... On the working ground, the vertical frame 11 is an overall vertical frame structure. A lifting adjustment part 12 is installed at the upper part of the vertical frame 11. The lifting adjustment part 12 is used to drive the working swing arm 13 to achieve lifting adjustment. The lifting adjustment part 12 adopts a structure of servo motor driving lead screw and threaded slider. A lifting seat is installed on the threaded slider. The working swing arm 13 and a telescopic drive part for driving the working swing arm 13 to extend and retract are installed on the lifting adjustment part 12 (lifting seat). The telescopic drive part (the telescopic drive part adopts the form of motor + gear + meshing rack, the meshing rack is installed on the working swing arm 13, and the motor + gear is installed on the lifting seat) is installed on the lifting adjustment part 12 (lifting seat). The working swing arm 13 is installed on the telescopic drive part, and the telescopic drive part can drive the working swing arm 13 to achieve extension and retraction. A partition feeding component 14 is installed on the working swing arm 13 for feeding the partition 3 into a preset position inside the cylinder 4. The partition feeding component 14 can be moved and adjusted on the working swing arm 13. At the same time, the first welding gun assembly 15 and the second welding gun assembly 16 work together to perform double-sided welding on the partition 3. The first welding gun assembly 15 is installed at the front end of the working swing arm 13, and the second welding gun assembly 16 is located on the lower side of the working swing arm 13. The second welding gun assembly 16 can be displaced and adjusted relative to the working swing arm 13. The welding auxiliary mechanism 2 includes an angle adjustment component 21 and a rotation component 22; the bottom of the angle adjustment component 21 is installed on the working ground, and the angle adjustment component 21 is used to drive the rotation component 22 to achieve angle adjustment, and the rotation component 22 is installed on the angle adjustment component 21 to provide rotational support for the cylinder 4.

[0019] As per the instruction manual Figure 3As shown, the partition feeding component 14, used to feed the partition 3 into a preset position inside the cylinder 4, includes a mounting side plate 141, a side plate drive motor 142, a side plate slider 143, and a partition support assembly 144. The side plate drive motor 142 primarily provides working power for the movement of the mounting side plate 141 and the partition support assembly 144. During installation, the side plate drive motor 142 is mounted on one end of the mounting side plate 141. A side plate slider 143, which mates with the side plate slide rail, is mounted on the inner side of the mounting side plate 141. Simultaneously, a working swing arm 13 is mounted on... It is equipped with a side plate slide rail and a side plate rack; during installation, the side plate slider 143 is slidably engaged on the side plate slide rail; a side plate gear is installed at the power output end of the side plate drive motor 142, and the side plate gear meshes with the side plate rack on the working swing arm 13. During operation, the side plate drive motor 142 drives the side plate gear to rotate, and the side plate gear meshes with the side plate rack to realize the automatic displacement adjustment of the mounting side plate 141, the partition support assembly 144 and the partition 3 thereon. The partition support assembly 144 is installed on the mounting side plate 141 for bearing and positioning the partition 3.

[0020] As per the instruction manual Figure 4 As shown, the partition support assembly 144 for displacing and supporting the partition 3 includes a side frame 441, an upper connecting rod 442, a lower connecting rod 443, an upper connecting frame 444, a lower connecting frame 445, and a partition positioning part 446. The side frame 441 is used to adapt to the adjustment and installation of the partition positioning part 446. During installation, the side frame 441 is installed at the ends of the upper connecting rod 442 and the lower connecting rod 443. The mounting side plate 141 is connected to the upper connecting rod 442 and the lower connecting rod 443 respectively via the upper connecting frame 444 and the lower connecting frame 445. (It should be noted that, to facilitate the installation and disassembly of the partition support assembly 144 and the mounting side plate 141, sliding holes are machined on the upper connecting frame 444 and the lower connecting frame 445. Threaded holes are machined radially within the sliding holes, and locking screws are installed in the threaded through holes.) 4. The lower connecting frame 445 is installed in conjunction with the upper connecting rod 442 and the lower connecting rod 443 through sliding holes. At the same time, pin columns are installed on the upper connecting frame 444 and the lower connecting frame 445. The mounting side plate 141 is machined with pin holes adapted to the installation of the pin columns. During use, the installer only needs to adjust the upper connecting frame 444 and the lower connecting frame 445 on the upper connecting rod 442 and the lower connecting rod 443 so that the upper connecting frame 444 and the lower connecting frame 445 can be separated and contacted through the pin columns and pin holes to realize the installation and disassembly between the partition support assembly 144 and the mounting side plate 141. This is very convenient for replacing the partition support assembly 144, so as to ensure that the mounting side plate 141 can meet the assembly of partition support assemblies 144 of different sizes and models. The partition positioning part 446 is movably and adjustablely installed on the side frame 441 to support and position the partition 3.

During installation, the movable adjustment block 461 is mounted on the side frame 441 and can be adjusted up and down on the side frame 441. After adjustment, it is locked to the side frame 441 by bolts. The inner end of the positioning support pin 462 is vertically fixedly mounted on the movable adjustment block 461. At the same time, a process through hole is machined on the partition 3. The partition 3 is installed on the positioning support pin 462 through the process through hole to realize the support of the positioning support pin 462 on the partition 3.

[0022] It should be further noted that, in order to ensure stable contact between the partition plate 3 and the positioning support pin 462, the positioning support pin 462 in this invention can adopt a conical structure as a whole. At the same time, an inner conical surface adapted to the conical structure on the positioning support pin 462 is machined in the process through hole. The partition plate 3 can fit against the outer conical surface of the positioning support pin 462 through the inner conical surface of the process through hole (at the same time, in order to ensure a stable fit between the partition plate 3 and the positioning support pin 462, the outer conical surface of the positioning support pin 462 can be magnetized and stably fitted with the partition plate 3 by magnetic adsorption). This achieves a stable fit between the partition plate 3 and the positioning support pin 462, ensuring the stability of the partition plate 3 when it enters the cylinder 4.

The push motor 651 is installed at the end of the guide housing 653 to drive the push screw 652 to rotate in both directions. A guide groove is machined inside the guide housing 653 to accommodate the sliding installation of the moving block 654. The moving block 654 is slidably installed in the guide groove, and a threaded through hole is opened in the center of the moving block 654. The moving block 654 is installed on the push screw 652 through the threaded through hole and threadedly engages with the push screw 652. The outer side of the moving block 654 is connected to the adjustment frame 164 and drives the adjustment frame 164 to move and adjust.

[0026] As per the instruction manual Figure 9As shown, the welding auxiliary mechanism 2 for driving the cylinder 4 to rotate and adjust its angle includes an angle adjustment component 21 and a rotation component 22; wherein, the angle adjustment component 21 is used to drive the rotation component 22 to achieve multi-directional angle adjustment; the rotation component 22 is used to provide rotational support for the cylinder 4; the angle adjustment component 21 includes a bearing frame 211, an angle adjustment drive 212, a fan-shaped adjustment assembly 213, and a rotation drive assembly 214; wherein, the angle adjustment drive 212 is mounted on the bearing frame 211 to drive the fan-shaped adjustment assembly 213 to achieve tilt angle adjustment, and the fan-shaped adjustment assembly 213 is mounted on the bearing frame 211 on both sides by a rotatable shaft support, and the fan-shaped adjustment... The integrated component 213 adopts a sector-shaped toothed plate structure. The angle adjustment drive 212 engages with the sector-shaped toothed plate in the sector-shaped adjustment component 213 through a motor and meshing gears. This drives the entire sector-shaped adjustment component 213 to adjust the tilt angle when the cylinder 4 needs to be tilted. At the same time, a rotary drive component 214 is installed on the sector-shaped adjustment component 213. The rotary drive component 214 adopts a structure of a motor and a small gear meshing with a large gear ring to drive the rotating component 22 to adjust the rotation angle. During installation, the rotating component 22 is connected to the large gear ring in the rotary drive component 214 by bolts. The angle adjustment drive 212 and the sector-shaped adjustment component 213 are in contact through tooth meshing.

[0027] As per the instruction manual Figure 10 As shown, the rotating component 22 used for rotating support and anti-fall limiting of the cylinder 4 includes a docking frame 221, a first rotating assembly 222, a second rotating assembly 223, and a side-stop limiting component 224; wherein, the docking frame 221 is used to install and support the first rotating assembly 222, the second rotating assembly 223, and the side-stop limiting component 224. The docking frame 221 is connected to the rotating drive assembly 214 by bolts. The first rotating assembly 222 and the second rotating assembly 223 are installed on the upper part of the docking frame 221. The first rotary group 222 and the second rotary group 223 work together to provide rotary support for the cylinder 4 during the welding process. It should be noted that the first rotary group 222 and the second rotary group 223 have the same structure and both adopt the common roller type rotary support method. At the same time, side stop limiting components 224 are installed on both sides of the docking frame 221. The side stop limiting components 224 are used to limit the contact of the cylinder 4 at the edge to prevent the cylinder 4 from slipping off the first rotary group 222 and the second rotary group 223 when tilted.

[0028] The specific operation process of the partition welding equipment for circular cylindrical bodies of the present invention is as follows: Step 1: First, the cylinder 4 to be welded can be hoisted onto the rotating component 22 in the welding auxiliary mechanism 2 using external mechanical hoisting equipment, ensuring that the outer circle of the cylinder 4 is fully in contact with the rotating wheels on the first rotating group 222 and the second rotating group 223 in the rotating component 22; Step 2: The rotation of the control angle adjustment component 21 drives the assembly 214 to work, and the rotation of the assembly 214 drives the rotary component 22 to achieve the rotation angle adjustment. Under the synergistic effect of the above adjustment, the cylinder 4 on the rotary component 22 is adjusted to the welding position. Step 3: Install the partition 3 on the partition feeding component 14. Specifically, process through holes are machined on the partition 3, and the partition 3 can be installed on the positioning support pin 462 on the partition positioning part 446 through the process through holes, so as to realize the support of the positioning support pin 462 on the partition 3. Step 4: Control the lifting adjustment part 12 in the welding operation mechanism 1 to work. The lifting adjustment part 12 drives the working swing arm 13 to adjust its height. When the height of the working swing arm 13 is adjusted to the correct position (it is necessary to ensure that the height of the working swing arm 13 is parallel and compatible with the center of the cylinder 4), control the telescopic drive part installed on the lifting adjustment part 12 (lifting seat) to work. The telescopic drive part adopts the form of motor + gear + meshing rack. The meshing rack is installed on the working swing arm 13, and the motor + gear is installed on the lifting seat. The telescopic drive part drives the working swing arm 13 to achieve telescopic movement. Step 5: Control the side plate drive motor 142 on the partition feeding component 14 to work. The side plate drive motor 142 drives the side plate gear to rotate clockwise. The side plate gear meshes with the side plate rack, thereby driving the mounting side plate 141, the partition support assembly 144 and the partition 3 on it to move into the inner cavity of the cylinder 4. After moving into place, the side plate drive motor 142 stops working. Step Six: At this time, the welding gun head in the first welding gun execution part 154 of the first welding gun assembly 15 is located at the outer edge of the partition 3. Then, the welding gun displacement adjustment part 165 in the second welding gun assembly 16 is controlled to work, the push motor 651 is started, the push screw 652 rotates and drives the moving block 654 to move the adjustment frame 164, the second welding gun frame 161, the second welding gun seat 162 and the second welding gun execution part 163 to the inner edge of the partition 3 in the inner cavity of the cylinder 4. When the welding gun head in the second welding gun execution part 163 is located at the inner edge of the partition 3, the push motor 651 stops working. At this time, the welding gun head in the first welding gun execution part 154 and the welding gun head in the second welding gun execution part 163 are respectively located at the inner and outer edges of the partition 3. Step 7: At this time, the welding gun head in the first welding gun execution unit 154 and the welding gun head in the second welding gun execution unit 163 can be controlled to work simultaneously to perform the first spot welding on the parts that contact the sides of the partition plate 3 with the inner wall of the cylinder 4. At this time, the position between the partition plate 3 and the inner wall of the cylinder 4 is determined. Subsequently, in order to avoid interference from the partition plate feeding component 14 when the cylinder 4 rotates, the operator can control the side plate drive motor 142 in the partition plate feeding component 14 to work. The side plate drive motor 142 drives the side plate gear to rotate counterclockwise. The side plate gear meshes with the side plate rack, thereby driving the mounting side plate 141 and the partition plate bearing assembly 144 to retract. The partition plate positioning part 446 and the positioning support pin 462 on the partition plate bearing assembly 144 disengage from the process through hole on the partition plate 3. At this time, the partition plate feeding component 14 retracts to the initial position, eliminating the rotational interference of the partition plate 3. Step 8: At this time, the rotating component 22 in the welding auxiliary mechanism 2 can be controlled to work. The first rotating group 222 and the second rotating group 223 in the rotating component 22 work together to rotate the cylinder 4. When the cylinder 4 rotates, it rotates together with the partition 3. At the same time, the welding gun head in the first welding gun execution part 154 and the welding gun head in the second welding gun execution part 163 on both sides of the partition 3 work simultaneously to perform synchronous welding operations on both sides of the partition 3.

[0029] Specific Embodiment 2: To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below in conjunction with another embodiment. This embodiment is mainly applicable to parts with added stiffening plate structures inside the cylinder 4 (see appendix to the specification). Figure 13 The welding of partition 3 inside is as per the instruction manual. Figure 12As shown, in this embodiment, partition positioning cylinder assemblies 145 are provided at the four corners of the partition support assembly 144. These assemblies 145 can be used to limit the partition 3, preventing it from slipping off the partition support assembly 144 during movement. The partition positioning cylinder assembly 145 adopts a rotary cylinder + stop block structure. The rotary cylinder can drive the stop block to limit the partition 3 during movement. Simultaneously, the partition positioning cylinder assembly 145 needs to release the limitation on the partition 3 after the initial spot welding between the bottom of the partition 3 and the inner stiffening plate of the cylinder 4. The specific operation process is as follows: the welding gun head in the first welding gun execution unit 154 and the welding gun head in the second welding gun execution unit 163 can be controlled to work simultaneously to perform the initial spot welding on the parts of the partition 3 that contact the inner stiffening plate of the cylinder 4. At this time, the position between the partition 3 and the inner stiffening plate of the cylinder 4 is determined. Subsequently, the partition... The rotary cylinder in the plate positioning cylinder assembly 145 drives the stop block to release the limiting interference on the partition 3. Then, the operator can control the side plate drive motor 142 in the partition feeding component 14 to work. The side plate drive motor 142 drives the side plate gear to rotate counterclockwise. The side plate gear meshes with the side plate rack, thereby driving the mounting side plate 141 and the partition support assembly 144 to retract. The partition positioning part 446 and the positioning support pin 462 on the partition support assembly 144 disengage from the process through hole on the partition 3. At this time, the partition feeding component 14 retracts to the initial position, releasing the rotational interference on the partition 3. The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed.
