Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe welding technology, specifically a corrugated pipe welding clamping fixture. Background Technology

[0002] Various types of pipe fittings are frequently used in many aspects of our lives, including bellows with welded flanges at both ends. These bellows assemblies need to ensure the coaxiality of the upper and lower flanges and the total height during positioning welding. Since there are connecting through holes on the upper and lower flanges, the relative angle relationship of the connecting through holes of the upper and lower flanges needs to be positioned. Furthermore, when rotating and welding precision bellows and flange openings, the accuracy of the welding position is very high. If the bellows opening or flange opening is deformed or moved, it will easily lead to welding deviation, affecting the accuracy and aesthetics of the welding. Therefore, bellows welding clamping fixtures are often used to fix them and prevent displacement between the two.

[0003] Chinese Utility Model Patent Publication No. CN207414565U discloses a bellows static sealing bellows welding clamping fixture. The specification of this fixture reveals that it uses a copper fitting to support the bellows welding surface, solving the support and positioning problems of the bellows welding area, avoiding welding burn-through, and addressing position adjustment issues during welding. This improves the sealing effect and significantly enhances product quality. The fixture has a compact structure, is easy to assemble and operate, and is reliable. However, while this bellows static sealing bellows welding clamping fixture avoids burn-through, the lack of a fixed structure causes deformation or movement of the pipe or flange opening during welding, affecting the accuracy and aesthetics of the welding. Furthermore, the lack of a rotating structure makes rotational welding difficult, requiring the fixture to be removed and re-welded, resulting in cumbersome operation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a bellows welding clamping fixture, which can effectively solve the problems in the prior art where the lack of a fixed structure causes deformation or movement of the pipe or flange opening during welding, affecting the accuracy and aesthetics of the welding, and the lack of a rotating structure makes it inconvenient to perform rotational welding, requiring the removal of the fixation and re-welding, resulting in a cumbersome operation.

[0005] The technical solution adopted by this utility model is as follows: a corrugated pipe welding clamping fixture, including a positioning plate, a welding part, a positioning sleeve and a welding gun. A sleeve is fixedly installed at one end of the positioning plate near the welding part. A limiting seat is fixedly installed at the inner edge of the sleeve. A rotating shaft is rotatably installed at the end of the limiting seat away from the sleeve. A corrugated pipe is sleeved at the inner edge of the sleeve. A connecting sleeve is fixedly installed at the end of the rotating shaft away from the limiting seat. A rotating welding positioning component is engaged at the end of the sleeve away from the positioning plate. A limiting plate is fixedly installed at the end of the rotating welding positioning component away from the sleeve. The connecting sleeve passes through the rotating welding positioning component and the limiting plate and abuts against the welding part. A positioning sleeve is provided at the other end of the welding part away from the positioning plate.

[0006] Preferably, a second rotating shaft is fixedly installed at the other end of the positioning sleeve away from the welded part, a second sleeve is provided on the outer edge of the second rotating shaft, and a rotating tail sleeve is fixedly installed at the other end of the second rotating shaft away from the positioning sleeve. The positioning sleeve and the second rotating shaft are fixedly installed, and the positioning sleeve abuts against the welded part.

[0007] Through the above technical solution, by designing the positioning sleeve, the second rotating shaft, and the rotating tail sleeve, when the positioning sleeve abuts against the welded part, the rotating tail sleeve can be rotated to drive the second rotating shaft to rotate, and the positioning sleeve can drive the welded part to rotate, thus realizing the rotation function, facilitating welding, and avoiding deformation or movement of the pipe or flange opening, which would affect the accuracy and aesthetics of the welding.

[0008] Preferably, the sleeve has a slot at the end away from the positioning plate, and the size of the slot is the same as the size of the rotary welding positioning component and the two offset each other.

[0009] Through the above technical solution, the design of the slot allows the rotary welding positioning component to be snapped into the slot during installation, facilitating rapid positioning of the rotary welding positioning component. Subsequently, the connecting sleeve passes through the rotary welding positioning component and abuts against the weldment, which facilitates subsequent welding.

[0010] Preferably, the rotary welding positioning assembly includes a rotary disk, a through hole is provided at the outer edge of the rotary disk, and a through groove is provided at the center of the rotary disk from the positioning disk to the welding part, and the connecting sleeve passes through the through groove and abuts against the welding part.

[0011] Through the above technical solution, the design of the rotating disk allows the connecting sleeve to pass through the through groove, and then the connecting sleeve abuts against the welded part, which can limit the position of the connecting sleeve. In addition, the design of the through groove allows it to achieve normal rotation function and avoids affecting its rotational welding.

[0012] Preferably, the limiting seat, the first rotating shaft, and the bellows are all located at the inner edge of the first sleeve, and the first rotating shaft and the bellows are in contact with each other.

[0013] Through the above technical solution, by designing the limiting seat, the first rotating shaft and the bellows, the bellows can be sleeved on the outer edge of the first rotating shaft before installing the rotating welding positioning component. Then, when performing rotating welding, the first rotating shaft can drive the bellows to rotate, thus realizing rotating welding.

[0014] Preferably, the welding torch is located at the connection between the connecting sleeve and the welded part, and the rotating shaft is adapted to the connecting sleeve.

[0015] Through the above technical solution and the design of the welding gun, when the connecting sleeve and the positioning sleeve respectively abut against the two ends of the welded part, the connection between the connecting sleeve and the positioning sleeve can be welded by the welding gun, and then the rapid welding of the connecting sleeve, the positioning sleeve and the welded part can be realized.

[0016] Preferably, the rotating shaft, the rotating tail sleeve, and the positioning sleeve are an integral structure, and the welded part is located between the connecting sleeve and the positioning sleeve.

[0017] Through the above technical solution, the rotation shaft, the rotating tail sleeve and the positioning sleeve are combined. Due to their integrated design, the welded parts can be rotated. Furthermore, the welded parts are located in the connecting sleeve and the positioning sleeve, which can play a fixing role.

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.

[0022] Example 1: As Figure 1-6 As shown, the present invention provides a corrugated pipe welding clamping fixture, including a positioning plate 1, a welding part 10, a positioning sleeve 11, and a welding torch 15. A sleeve 2 is fixedly installed at one end of the positioning plate 1 near the welding part 10. A limiting seat 3 is fixedly installed at the inner edge of the sleeve 2. A rotating shaft 4 is rotatably installed at the end of the limiting seat 3 away from the sleeve 2. A corrugated pipe 5 is sleeved at the inner edge of the sleeve 2. A connecting sleeve 6 is fixedly installed at the end of the rotating shaft 4 away from the limiting seat 3. A rotating welding positioning component 8 is snapped into the end of the sleeve 2 away from the positioning plate 1. A limiting plate 9 is fixedly installed at the end of the rotating welding positioning component 8 away from the sleeve 2. The connecting sleeve 6 passes through the rotating welding positioning component 8 and the limiting plate 9 and abuts against the welding part 10. A positioning sleeve 11 is provided at the other end of the welding part 10 away from the positioning plate 1.

[0023] Specifically, a rotating shaft 12 is fixedly installed at the other end of the positioning sleeve 11 away from the welding part 10. A sleeve 13 is provided on the outer edge of the rotating shaft 12. A rotating tail sleeve 14 is fixedly installed at the other end of the rotating shaft 12 away from the positioning sleeve 11. The positioning sleeve 11 and the rotating shaft 12 are fixedly installed, and the positioning sleeve 11 abuts against the welding part 10. The advantage is that, through the design of the positioning sleeve 11, the rotating shaft 12 and the rotating tail sleeve 14, when the positioning sleeve 11 abuts against the welding part 10, the rotating tail sleeve 14 can be rotated to drive the rotating shaft 12 to rotate, and the positioning sleeve 11 can drive the welding part 10 to rotate. This can realize the rotation function, facilitate welding, and avoid deformation or movement of the pipe or flange opening, which would affect the accuracy and aesthetics of the welding.

[0024] Specifically, the sleeve 2, away from the positioning plate 1, has a slot 7. The size of the slot 7 is the same as that of the rotary welding positioning component 8, and the two abut against each other. The advantage is that, through the design of the slot 7, when installing the rotary welding positioning component 8, the rotary welding positioning component 8 can be snapped into the slot 7, which can facilitate the rapid positioning of the rotary welding positioning component 8. Then, the connecting sleeve 6 passes through the rotary welding positioning component 8 and abuts against the welding part 10, which can facilitate subsequent welding.

[0025] Specifically, the rotary welding positioning assembly 8 includes a rotary disk 801, with a through hole 802 extending through the outer edge of the rotary disk 801. A through groove 803 extends from the positioning disk 1 to the welding part 10 near the center of the rotary disk 801. The connecting sleeve 6 passes through the through groove 803 and abuts against the welding part 10. The advantage is that the design of the rotary disk 801 allows the connecting sleeve 6 to pass through the through groove 803 and then abut against the welding part 10, which can limit the position of the connecting sleeve 6. In addition, the design of the through groove 803 allows it to achieve normal rotation function and avoids affecting its rotary welding.

[0026] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, the limiting seat 3, the rotating shaft 4, and the bellows 5 are all located at the inner edge of the sleeve 2. The rotating shaft 4 and the bellows 5 are in close contact. The advantage is that, through the design of the limiting seat 3, the rotating shaft 4, and the bellows 5, the bellows 5 can be sleeved on the outer edge of the rotating shaft 4 before the rotating welding positioning assembly 8 is installed. Then, when rotating welding is performed, the rotating shaft 4 can drive the bellows 5 to rotate, thus realizing rotating welding.

[0028] Specifically, the welding torch 15 is located at the connection between the connecting sleeve 6 and the welding part 10. The rotating shaft 4 is adapted to the connecting sleeve 6. The advantage is that, through the design of the welding torch 15, when the connecting sleeve 6 and the positioning sleeve 11 respectively abut against the two ends of the welding part 10, the connection between the connecting sleeve 6 and the positioning sleeve 11 can be welded by the welding torch 15, and then the rapid welding of the connecting sleeve 6, the positioning sleeve 11 and the welding part 10 can be realized.

[0029] Specifically, the rotating shaft 12, the rotating tail sleeve 14, and the positioning sleeve 11 are an integral structure. The welded part 10 is located between the connecting sleeve 6 and the positioning sleeve 11. The advantage is that, through the cooperation of the rotating shaft 12, the rotating tail sleeve 14, and the positioning sleeve 11, due to their integral design, the rotation of the welded part 10 can be achieved. Furthermore, the welded part 10, located between the connecting sleeve 6 and the positioning sleeve 11, can play a fixing role.

[0030] Working Principle: During use, the design of the positioning sleeve 11, rotating shaft 12, and rotating tail sleeve 14 allows the positioning sleeve 11 to abut against the welded part 10. Rotating the rotating tail sleeve 14 causes the rotating shaft 12 to rotate, which in turn causes the positioning sleeve 11 to rotate the welded part 10. This rotation facilitates welding and prevents deformation or movement of the pipe or flange openings, thus ensuring welding accuracy and aesthetics. The slot 7 allows the rotating welding positioning assembly 8 to be quickly positioned during installation. The connecting sleeve 6 then passes through the rotating welding positioning assembly 8, abutting against the welded part 10 for subsequent welding. The rotating disk 801 allows the connecting sleeve 6 to pass through the through slot 803, further abutting against the welded part 10 and providing a limiting position for the connecting sleeve 6. The design of the through groove 803 allows it to rotate normally without affecting the rotational welding. The design of the limit seat 3, rotating shaft 4, and bellows 5 allows the bellows 5 to be fitted onto the outer edge of the rotating shaft 4 before installing the rotational welding positioning assembly 8. During rotational welding, the rotating shaft 4 drives the bellows 5 to rotate, achieving rotational welding. The welding torch 15 allows the connection between the connecting sleeve 6 and the positioning sleeve 11 to be welded together after the connecting sleeve 6 and positioning sleeve 11 abut against the two ends of the welded part 10. This enables rapid welding of the connecting sleeve 6, positioning sleeve 11, and welded part 10. The rotating shaft 12, rotating tail sleeve 14, and positioning sleeve 11, due to their integrated design, allow the welded part 10 to rotate. Furthermore, the welded part 10's location on the connecting sleeve 6 and positioning sleeve 11 provides a fixing function.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
