Description

Technical Field

[0001] This utility model relates to welding auxiliary devices, specifically to the field of welding fixtures, and more specifically to a welding auxiliary device for automatic pipeline welding equipment. Background Technology

[0002] Prefabrication of pipelines in factories is the direction of industrial construction projects. Due to the superior construction environment in factories, the use of automated welding is also the first choice to improve the efficiency of pipeline prefabrication. Pipeline prefabrication mostly involves welding between straight pipe sections and pipe fittings. For straight pipe sections that are long and easy to clamp with automatic welding, automatic welding can be performed. However, for short straight pipe sections, automatic welding clamping devices cannot clamp them. Such welds can only be welded manually in daily construction and cannot be welded automatically. The auxiliary device of this invention can connect the pipe section to be processed to a straight pipe into a whole. By clamping and rotating the straight pipe, the weld on the pipe section to be processed can be automatically welded.

[0003] Secondly, automated welding fixtures are tools used to automate welding processes, typically in large-scale production lines or robotic welding systems. These fixtures are designed to hold and position workpieces to ensure accuracy and consistency during the welding process. They are usually designed to integrate seamlessly with welding robots or automated welding equipment, allowing for seamless integration with the entire production flow. They may employ various automation technologies, such as sensors, electric actuators, or pneumatic devices, to achieve automated clamping and positioning functions.

[0004] However, most auxiliary welding fixtures currently have the following problems:

[0005] For example, a pipe welding fixture with publication number CN202020714235.8, although convenient for limiting the welding of pipes, can only clamp and weld a single pipe at a time, and cannot simultaneously place and adjust multiple pipes for clamping, making it cumbersome to use and inconvenient to clamp and limit the placement of pipes according to the usage situation. At the same time, most existing automatic auxiliary welding fixtures are large in size, occupying a lot of space when not in use, and when the pipes to be welded are large, the equipment cannot be placed and clamped stably, affecting the processing efficiency and making it inconvenient to conveniently assemble and use the equipment.

[0006] Therefore, we have made improvements to this and proposed a welding auxiliary device for automatic pipeline welding equipment. Utility Model Content

[0007] The purpose of this utility model is to address the current problems of inconvenience in clamping and limiting the placement of pipes according to usage conditions, and inconvenience in conveniently assembling and using equipment.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] Automated auxiliary welding fixtures are used to improve the above-mentioned problems.

[0010] The application is as follows:

[0011] The device includes a mounting plate and a through hole. The mounting plate has a through hole and a mounting groove. The mounting groove has a splicing groove and a fixing box. A spring is fixedly connected to the fixing box. A limit plate is fixedly connected to the other end of the spring. A first locking block and a pull plate are fixedly connected to the limit plate. A second locking block is fixedly connected to the fixing box. A connecting screw is installed in the through hole. A limit nut is threaded onto the connecting screw. A support plate is fixedly connected to the connecting screw. A rotating component is rotatably connected to the support plate. A bidirectional threaded rod is threaded onto the rotating component. The bidirectional threaded rod is rotatably connected to the support plate. A moving block is threaded onto the bidirectional threaded rod. A push plate is rotatably connected to the moving block.

[0012] As a preferred technical solution of this application, the springs are symmetrically distributed on the left and right sides inside the fixed box, and the springs correspond one-to-one with the first locking blocks through the limiting plates.

[0013] As a preferred technical solution of this application, the side end face of the limiting plate is in contact with the inner side of the fixing box, and the first card block is fixedly connected to the center part of one side of the limiting plate.

[0014] As a preferred technical solution of this application, the second card blocks are equidistantly distributed on the fixed box, and the rotating component is fixedly connected to the center of one end of the bidirectional threaded rod.

[0015] As a preferred technical solution of this application, the moving blocks are symmetrically distributed on the left and right sides of the bidirectional threaded rod, and the moving blocks correspond one-to-one with the push plates.

[0016] As a preferred technical solution of this application, the other end of the push plate is rotatably connected to a clamping plate, and an anti-slip pad is fixedly connected to the clamping plate. The side end face of the moving block is in contact with the inner side face of the support plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. By using the support plate, when clamping and limiting multiple sections of the pipeline, the connecting screw on the support plate can be inserted into the through holes on both sides of the pipeline placed on the mounting plate. Then, the support plate is fixed and limited by the cooperation of the limiting nut and the connecting screw. By installing the support plate on multiple sections of the pipeline, multiple sections can be clamped. Rotating the rotating part on the support plate drives the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it can drive the moving blocks on both sides to move. When the moving blocks on both sides move inward at the same time, they can push the push plate to move the clamping plate. Under the clamping of the clamping plates on both sides of the pipeline, the pipeline can be clamped and limited, avoiding pipeline displacement during welding and affecting processing stability.

[0020] 2. With the installation plates in place, if the pipe to be welded is large and the usable area of ​​the installation plates needs to be increased, multiple installation plates can be placed and pressed together. The pull plates on both sides of the fixing box are then pressed together, and the pull plates drive the limiting plates to move. When the limiting plates move, they can retract the first locking block into the fixing box. At the same time, the limiting plates compress the spring. Then, the fixing box and the multiple second locking blocks installed are inserted into the splicing slot in the installation groove. Then, the pull plates on both sides are opened, and the limiting plates are driven by the spring to reset. At the same time, the limiting plates push out the first locking block and engage it in the installation plates on both sides, thus engaging and installing the placed installation plates, improving installation stability, and facilitating splicing according to the estimated usage conditions.

[0021] 3. The auxiliary device of the present invention can... Figure 7 The straight pipe section is connected to the pipe section to be processed into a whole.

[0022] 4. During welding, the automatic welding machine's clamping device clamps the straight pipe section and rotates it, while the welding torch... Figure 7 Welding is performed while keeping the indicated position fixed. After rotating one revolution, the welding of the entire circumferential weld is completed.

[0023] 5. When connecting, it is necessary to ensure that the straight pipe section is coaxial with the circumferential weld. This will ensure that the distance between the welding torch and the weld is stable during rotation, thereby ensuring the welding quality.

[0024] 6. The clamping device of this invention is easy to assemble and disassemble, and can be used for pipe sections of different diameters. During use, assembly can be completed quickly, improving work efficiency. Attached Figure Description

[0040] Example 2:

[0041] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:

[0042] like Figure 5 As shown, in a preferred embodiment, based on the above method, the springs 6 are symmetrically distributed on the left and right sides inside the fixed box 5. The springs 6 correspond one-to-one with the first locking blocks 8 through the limiting plates 7, which can ensure that the mounting plates 1 on both sides can be installed and used stably with the cooperation of the first locking blocks 8 on both sides.

[0043] like Figure 5 As shown, in a preferred embodiment, based on the above method, the side end face of the limiting plate 7 is further fitted with the inner side of the fixing box 5, and the first locking block 8 is fixedly connected to the center part of one side of the limiting plate 7, which can ensure that the limiting plate 7 can move smoothly with the support of the inner side of the fixing box 5 when it moves.

[0044] like Figure 4 As shown, in a preferred embodiment, based on the above method, the second locking blocks 10 are further distributed equidistantly on the fixed box 5, and the rotating part 14 is fixedly connected to the center of one end of the bidirectional threaded rod 15, which can ensure that when the rotating part 14 is rotated, the bidirectional threaded rod 15 can be driven to run smoothly.

[0045] like Figure 4 As shown, in a preferred embodiment, based on the above method, the moving blocks 16 are symmetrically distributed on the left and right sides of the bidirectional threaded rod 15, and the moving blocks 16 correspond one-to-one with the push plates 17, which can ensure that the push plates 17 on both sides can push the clamping plates 18 to move smoothly.

[0046] like Figure 4 As shown, in a preferred embodiment, based on the above method, the other end of the push plate 17 is rotatably connected to a clamping plate 18, and an anti-slip pad 19 is fixedly connected to the clamping plate 18. The side end face of the moving block 16 is in contact with the inner side of the support plate 13, which can ensure that the moving block 16 can move smoothly with the support of the inner side of the support plate 13 when it moves.

[0047] Specifically, when using this automatic auxiliary welding fixture: (in conjunction with...) Figure 1-6 If the pipe to be welded is large and the usable area of ​​the mounting plate 1 needs to be increased, multiple mounting plates 1 can be placed together and pressed against the pull plates 9 on both sides of the fixing box 5. The pull plates 9 drive the limiting plate 7 to move. When the limiting plate 7 moves, it can retract the first locking block 8 into the fixing box 5. At the same time, the limiting plate 7 compresses the spring 6. Then, the fixing box 5 and the multiple installed second locking blocks 10 are inserted into the splicing slot 4 in the mounting slot 3. Then, the pull plates 9 on both sides are opened. Under the push of the spring 6, the limiting plate 7 is reset. At the same time, the limiting plate 7 pushes out the first locking block 8 and locks it into the mounting plates 1 on both sides. The placed mounting plates 1 are locked and installed, which improves the installation stability and makes it convenient to estimate the use situation for splicing. When it is necessary to disassemble the spliced ​​mounting plates 1 to save space, the same operation can be performed to retract the first locking block 8 into the fixing box 5 and disassemble and install the spliced ​​mounting plates 1. This makes it convenient to adjust the installation according to the size and length of the welded pipe, improves the welding stability, and after the installation is completed, the equipment can be placed next to the automatic welding robot for auxiliary welding.

[0048] After installing mounting plate 1, place the pipes to be welded on mounting plate 1. Workers use a handheld leveling device to align the straight and bent sections of the pipes coaxially. To improve the stability of the pipe clamping, the connecting screws 11 on the support plate 13 can be inserted into the through holes 2 on both sides of the pipe placed on mounting plate 1. Then, the support plate 13 is fixed and limited by the cooperation of the limiting nut 12 and the connecting screw 11. By installing the support plate 13 on multiple sections of the pipe, multiple sections can be clamped. The support plate 13 can be rotated... The rotating component 14 drives the bidirectional threaded rod 15 to rotate. When the bidirectional threaded rod 15 rotates, it can drive the two moving blocks 16 on both sides to move. When the two moving blocks 16 move inward at the same time, they can push the push plate 17 to drive the clamping plate 18 to move. The pipe can be clamped and limited by the cooperation of the clamping plates 18 on both sides and the anti-slip pad 19. Multiple support plates 13 can be installed on the left and right sides of the pipe to clamp and limit multiple sections, so as to avoid the pipe from shifting during welding and affecting the processing stability.

[0049] like Figure 4 As shown, a pipe fitting component 20 can be further connected to the outside of the anti-slip pad 19. The pipe fitting component can be designed to fit the outer wall of various pipes, and can be arc-shaped or K-shaped to better fit the pipe. The pipe fitting component 20 can be further designed to be detachable and replaceable according to different pipe diameters for easy clamping.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, as well as all technical solutions and improvements that do not depart from the spirit and scope of practicality, are covered within the scope of the claims of the present utility model.
