Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, and in particular to an economizer tube bank welding auxiliary alignment device. Background Technology

[0002] During the economizer tube bank welding process, due to the high precision requirements of tube bank docking, traditional docking methods suffer from problems such as docking difficulties and unstable welding quality. To solve this problem, an economizer tube bank welding auxiliary alignment device was developed. It aims to improve the docking precision of tube banks, reduce manual operation, ensure the stability of the welding process and the quality of the weld, thereby improving the operating efficiency and service life of the equipment.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing economizer tube bank welding auxiliary alignment device cannot achieve precise positioning, stable clamping, and rotation adjustment of the tube body, thus failing to ensure welding alignment accuracy and welding efficiency. Inaccurate tube positioning can lead to deviations in the horizontal, vertical, or height directions of the tube opening, making precise alignment impossible. Unstable tube clamping or positioning errors can cause uneven stress on the welded joint. When the tube body is not positioned accurately or the clamping is unstable, operators need to frequently manually adjust the position of the tube bank. The lack of rotation adjustment function may prevent flexible angle adjustment during tube bank welding, limiting the continuity of automated welding. Rotation adjustment is a necessary condition for automated welding. The inability to adjust the tube angle will limit the use of automated equipment, prolong welding preparation time, increase labor costs and labor intensity, and make it difficult to guarantee adjustment accuracy.

[0004] Therefore, this utility model proposes an auxiliary alignment device for economizer tube welding to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary alignment device for economizer tube welding.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an economizer tube bank welding auxiliary alignment device, including a base plate, and further comprising:

[0007] An alignment assembly includes a support base connected to a base plate, a first guide wheel rotatably connected to the support base, a second guide wheel rotatably connected to the side of the support base away from the first guide wheel, a guide rod connected to the support base, a moving block slidably connected to the guide rod, a limit rod slidably connected to the moving block, a pressure block connected to the bottom of the limit rod, and a telescopic spring provided on the pressure block.

[0008] An auxiliary welding assembly includes a support block connected to a base plate, a rotating plate rotatably connected to the support block, a cylinder mounted on the rotating plate, a clamping block provided at the output end of the cylinder, a second drive motor mounted on the support block, a rotating wheel connected to the output end of the second drive motor, and the rotating wheel located at the bottom of the rotating plate.

[0009] Furthermore, a first drive motor is installed inside the support base, and a first drive wheel is connected to the output end of the first drive motor.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the first drive motor is installed inside the support base, and after starting, it drives the first drive wheel at the output end to rotate. The first drive wheel transmits power to the second drive wheel through the belt, thereby driving the second guide wheel to rotate synchronously.

[0011] Furthermore, a belt is provided on the first transmission wheel, and a second transmission wheel is provided on the belt, the second transmission wheel being connected to the second guide wheel.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the tubes on the first guide wheel and the second guide wheel are moved smoothly to the predetermined position before welding, so as to achieve the initial positioning of tube end alignment.

[0013] Furthermore, one end of the telescopic spring is connected to the moving block, and the other end of the telescopic spring is connected to the pressure block.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the two ends of the telescopic spring are respectively connected to the moving block and the pressure block. When the pressure block is driven to press down on the tube, the telescopic spring generates an elastic reaction force due to compression. This force makes the pressure block evenly fit against the surface of the tube. It can provide sufficient pressure to prevent the tube from shifting, and can also avoid rigid damage to the tube through elastic buffering. The telescopic spring can be adjusted by the pressing depth of the limit rod to adapt to the clamping requirements of different tube diameters.

[0015] Furthermore, a limiting hole is provided on the guide rod, and a limiting pin is provided on the moving block, with the limiting pin disposed within the limiting hole.

[0016] The beneficial effects of adopting the above-mentioned further solution are: multiple limiting holes are opened on the guide rod, the moving block slides with the guide rod, and when the moving block slides to the predetermined position, the limiting pin is inserted into the limiting hole at the corresponding position to lock the moving block, allowing the action position of the pressure block to be flexibly adjusted according to different pipe diameters.

[0017] Furthermore, a limiting seat is connected to the rotating plate, and the clamping block is slidably connected within the limiting seat.

[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: the rotating plate is rotatably connected to the support block, the second transmission motor drives the rotating wheel to rotate the rotating plate around the axis, the limiting seat is fixed on the surface of the rotating plate, the clamping block is slidably engaged with the limiting seat, and when the cylinder pushes the clamping block to slide along the limiting seat to clamp the pipe body, the rotation of the rotating plate can drive the pipe body to achieve circumferential rotation, which facilitates the ring welding of the pipe end and improves the welding efficiency and quality uniformity.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the tube to be welded is first placed on the first and second guide wheels of the alignment assembly, and then placed inside the support block and rotating plate. The output end of the cylinder pushes the clamping block to move, clamping and fixing one end of the tube to ensure the stability of the welding process. Subsequently, the moving block on the guide rod is slid to a predetermined position, and the limiting rod and the telescopic spring drive the pressure block to press down. Through the elastic action of the telescopic spring, the pressure block restricts the other end of the tube to prevent displacement during the welding process, ensuring precise horizontal alignment of the tube opening. The second drive motor drives the rotating wheel to rotate, causing the rotating plate to rotate on the support block, thus rotating the tube to facilitate welding of the aligned tube. This achieves precise positioning, stable clamping, and rotation adjustment of the tube, ensuring welding alignment accuracy and welding efficiency. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] like Figure 1 - Figure 5 As shown, this embodiment provides a technical solution: an economizer tube bank welding auxiliary alignment device, including a base plate 1, and further including:

[0032] Alignment component 2 includes a support base 21 connected to the base plate 1, a first guide wheel 22 rotatably connected to the support base 21, a second guide wheel 23 rotatably connected to the side of the support base 21 away from the first guide wheel 22, a guide rod 28 connected to the support base 21, a moving block 29 slidably connected to the guide rod 28, a limit rod 210 slidably connected to the moving block 29, a pressure block 211 connected to the bottom of the limit rod 210, and a telescopic spring 212 provided on the pressure block 211;

[0033] The auxiliary welding assembly 3 includes a support block 31 connected to the base plate 1, a rotating plate 32 rotatably connected to the support block 31, a cylinder 33 mounted on the rotating plate 32, a clamping block 35 provided at the output end of the cylinder 33, and a second drive motor 36 mounted on the support block 31. A rotating wheel 37 is connected to the output end of the second drive motor 36 and is located at the bottom of the rotating plate 32. First, the pipe to be welded is placed on the first guide wheel 22 and the second guide wheel 23 of the alignment assembly 2, and then placed inside the support block 31 and the rotating plate 32. The output end of the cylinder 33 pushes the clamping block 35 to move, clamping one end of the pipe. To ensure the stability of the welding process, the guide rod 28 is slid to a predetermined position. The limit rod 210 and the telescopic spring 212 drive the pressure block 211 to press down. Through the elastic action of the telescopic spring 212, the pressure block 211 restricts the other end of the tube body to prevent displacement during the welding process, ensuring precise horizontal alignment of the tube opening. The second drive motor 36 drives the rotating wheel 37 to rotate, which in turn drives the rotating plate 32 to rotate on the support block 31, causing the tube body to rotate. This facilitates welding of the aligned tube body, achieving precise positioning, stable clamping, and rotation adjustment of the tube body, ensuring welding alignment accuracy and welding efficiency.

[0034] The above solutions also have the problem that, when the economizer tube bank is aligned by welding assistance, the position of the pressure block 211 cannot be flexibly adjusted according to different tube diameters. Figure 1 - Figure 3As shown: A first drive motor 24 is installed inside the support base 21. A first drive wheel 25 is connected to the output end of the first drive motor 24. The first drive motor 24 is installed inside the support base 21. After starting, it drives the first drive wheel 25 at the output end to rotate. The first drive wheel 25 transmits power to the second drive wheel 27 through the belt 26, which in turn drives the second guide wheel 23 to rotate synchronously. The belt 26 is provided on the first drive wheel 25, and the second drive wheel 27 is provided on the belt 26. The second drive wheel 27 is connected to the second guide wheel 23. Before welding, the tubes on the first guide wheel 22 and the second guide wheel 23 are smoothly moved to the predetermined position to achieve the initial positioning of the tube opening alignment. One end of the telescopic spring 212 is connected to the moving block 29, and the other end of the telescopic spring 212 is connected to the pressure block 211. The two ends of the telescopic spring 212 are respectively connected to the moving block. When the pressure block 211 is pressed down on the pipe body, the telescopic spring 212 generates an elastic reaction force due to compression. This force makes the pressure block 211 evenly fit against the surface of the pipe body, which can provide sufficient pressure to prevent pipe displacement and avoid rigid damage to the pipe body through elastic buffering. The telescopic spring 212 can be adjusted by the pressing depth of the limiting rod 210 to adapt to the clamping requirements of different pipe diameters. The guide rod 28 is provided with a limiting hole 213, and the moving block 29 is provided with a limiting pin 214. The limiting pin 214 is set in the limiting hole 213. The guide rod 28 is provided with multiple limiting holes 213. The moving block 29 and the guide rod 28 slide together. When the moving block 29 slides to the predetermined position, the limiting pin 214 is inserted into the corresponding limiting hole 213 to lock the moving block 29. This allows the position of the pressure block 211 to be flexibly adjusted according to different pipe diameters.

[0035] like Figure 1 as well as Figure 4 As shown, a limiting seat 34 is connected to the rotating plate 32, and a clamping block 35 is slidably connected inside the limiting seat 34. The rotating plate 32 is rotatably connected to the support block 31. The second transmission motor 36 drives the rotating wheel 37 to rotate the rotating plate 32 around the axis. The limiting seat 34 is fixed to the surface of the rotating plate 32, and the clamping block 35 is slidably engaged with the limiting seat 34. When the cylinder 33 pushes the clamping block 35 to slide along the limiting seat 34 to clamp the pipe body, the rotation of the rotating plate 32 can drive the pipe body to rotate circumferentially, which facilitates the ring welding of the pipe end and improves the welding efficiency and quality uniformity.

[0036] Working principle:

[0037] like Figure 1 - Figure 5As shown, before the operation begins, the pipe to be welded is first placed on the first guide wheel 22 and the second guide wheel 23 of the alignment assembly 2. The alignment assembly 2 then begins to perform its initial positioning function. The first drive motor 24 inside the support base 21 is started, driving the first drive wheel 25 at its output end to rotate. The first drive wheel 25 transmits power to the second drive wheel 27 via the belt 26, which in turn drives the second guide wheel 23 to rotate synchronously, allowing the pipe to move smoothly on the first guide wheel 22 and the second guide wheel 23. This moves the pipe into the support block 31 and the rotating plate 32, achieving the initial positioning of the pipe end alignment. At this time, the cylinder 33 in the auxiliary welding assembly 3 is started, and its output end pushes the clamping block 35 to slide within the limiting seat 34, clamping and fixing one end of the pipe, providing a stable foundation for subsequent operations. To further ensure the stability of the pipe during welding, the moving block 2 on the guide rod 28 is moved... 9. Slide to the predetermined position, causing the pressure block 211 to press down. Since the telescopic spring 212 is connected between the moving block 29 and the pressure block 211, the telescopic spring 212 is compressed when pressed down, generating an elastic reaction force, so that the pressure block 211 is evenly attached to the surface of the pipe body. This provides sufficient pressure to prevent pipe displacement and avoids rigid damage through elastic buffering. The moving block 29 is locked by inserting the limiting pin 214 on the moving block 29 into the limiting hole 213 at the corresponding position of the guide rod 28. The pressing depth of the limiting rod 210 can be adjusted according to the pipe diameter. Subsequently, the second drive motor 36 of the auxiliary welding assembly 3 starts, and the rotating wheel 37 at its output end drives the rotating plate 32 to rotate on the support block 31, thereby causing the pipe body to rotate. At this time, the pipe body is in a state of precise positioning, stable clamping and flexible rotation, which facilitates welding operation and achieves the goal of precise alignment and efficient welding during the pipe welding process.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
