AI Technical Summary
In existing technologies, corrugated pipes lack stable positioning during welding, making them prone to displacement or falling off, which affects welding efficiency and practicality.
By employing a combination of placement mechanism and stabilizing components, the bellows is rotated by a motor-driven moving block and rotating roller, and welding is performed by a welding machine driven by the stabilizing components and electric cylinder, ensuring that the bellows does not easily shift during rotation.
This method ensures stable placement of the corrugated pipe during the welding process, improving welding efficiency and practicality, and avoiding problems such as displacement and falling.

[0026] Example
[0027] Please see Figure 1 and Figure 2 A non-correction spiral corrugated pipe welding structure includes a workbench 1 and a corrugated pipe 3, with an mounting plate 2 fixedly installed on the workbench 1.
[0028] Please see Figure 1-3 The workbench 1 is equipped with a placement mechanism on which the corrugated pipe 3 is placed. The placement mechanism includes two moving blocks 6. A slide groove is provided on the workbench 1, and both moving blocks 6 are slidably connected to the slide groove. A first motor 4 is fixedly installed on the workbench 1, and a rotating shaft 5 is fixedly installed at the output end of the first motor 4. The rotating shaft 5 is rotatably connected to the slide groove. By starting the first motor 4, the first motor 4 provides power to drive the rotating shaft 5 to rotate. The rotating shaft 5 has a first thread and a second thread symmetrically provided. The two moving blocks 6 have a first thread hole and a second thread hole respectively. The two moving blocks 6 are screwed onto the rotating shaft 5. Through the cooperation of the two moving blocks 6 and the rotating shaft 5, the two moving blocks 6 move on the rotating shaft 5. In the relative moving operation, the positions of the two moving blocks 6 are adjusted according to the size of the corrugated pipe 3. Two support rollers 7 are symmetrically rotated on each of the two moving blocks 6. The corrugated pipe 3 is placed on the four support rollers 7. Each of the two moving blocks 6 has a working chamber. A second motor 8 is fixedly installed in each of the two working chambers. A rotating roller 9 is fixedly installed at the output end of each of the two second motors 8. One end of the rotating roller 9 is rotatably connected to the working chamber. Each support roller 7 and the two rotating rollers 9 are in contact with the outer wall of the corrugated pipe 3. The two second motors 8 are started simultaneously by an external controller, so that the two second motors 8 drive the two rotating rollers 9 to rotate. Thus, the corrugated pipe 3 is rotated by the friction between the two rotating rollers 9 and the corrugated pipe 3.
[0029] Please see Figure 1 , Figure 2 and Figure 4 An electric cylinder 10 is fixedly installed on the mounting plate 2, and a connecting plate 11 is fixedly installed on the electric cylinder 10. A welding machine 12 is installed on the connecting plate 11. Two stabilizing components are symmetrically arranged on the mounting plate 2 for stabilizing and limiting the corrugated pipe 3. The corrugated pipe 3 is stabilized by the cooperation of the two stabilizing components, so that the corrugated pipe 3 is not easy to deviate when rotating. The electric cylinder 10 drives the connecting plate 11 and the welding machine 12 to move. The corrugated pipe 3 is welded by the contact between the welding machine 12 and the corrugated pipe 3.
[0030] Please see Figure 1 , Figure 2 and Figure 4 One of the stabilizing components includes a stabilizing plate 13, which is located at the bottom of the mounting plate 2. The stabilizing plate 13 is attached to the outer wall of the corrugated pipe 3. A screw 14 is rotatably mounted on the stabilizing plate 13 and screwed onto the mounting plate 2. Two first telescopic columns 15 are symmetrically fixedly mounted on the stabilizing plate 13, and the other ends of the two first telescopic columns 15 are fixedly connected to the mounting plate 2. By rotating the screw 14, the screw 14 moves on the mounting plate 2, thereby driving the stabilizing plate 13 to move. Through the attachment of the stabilizing plate 13 to the corrugated pipe 3, the corrugated pipe 3 is stabilized and limited, preventing the corrugated pipe 3 from shifting.
[0031] Please see Figure 1-3 A fixed block 16 is fixedly installed on the workbench 1, an electric push rod 17 is fixedly installed on the fixed block 16, and a support plate 18 is fixedly installed on the electric push rod 17. By activating the electric push rod 17, the electric push rod 17 drives the support plate 18 to move, so that the support plate 18 fits against the bottom outer wall of the corrugated pipe 3, thereby supporting the corrugated pipe 3 and making the corrugated pipe 3 more stable.
[0032] Please see Figure 4 It should also be noted that multiple auxiliary rollers 19 are rotatably mounted on the inner walls of both bellows 3, and the bellows 3 are rotated by the setting of multiple auxiliary rollers 19.
[0033] Please see Figure 1-3 Two second telescopic columns 20 are symmetrically fixedly installed on each of the two moving blocks 6. The other end of each second telescopic column 20 is fixedly connected to the mounting plate 2. The arrangement of multiple second telescopic columns 20 makes the two moving blocks 6 more stable when moving.
[0034] Please see Figure 1-3 Support plates 21 are fixedly installed on the two working chambers of the two moving blocks 6. The output bottom ends of the two second motors 8 are rotatably connected to the two support plates 21. The two support plates 21 make the two second motors 8 and the two rotating rollers 9 more stable.
[0035] In summary, when using this self-correcting spiral corrugated pipe welding structure, the first motor 4 is started. This motor is a commercially available device known to those skilled in the art; we are only using it practically without making any structural or functional improvements, which we will not elaborate on here. The motor is equipped with a matching control switch, the installation position of which is selected according to actual practical needs to facilitate operation and control by the operator. The first motor 4 provides power to drive the rotating shaft 5 to rotate. Through the cooperation of the two moving blocks 6 and the rotating shaft 5, the two moving blocks 6 move relative to each other on the rotating shaft 5. The position of the two moving blocks 6 is adjusted according to the size of the corrugated pipe 3, and the corrugated pipe 3 is placed on the four support rollers. On 7, two second motors 8 are started simultaneously by an external controller, causing the two second motors 8 to drive two rotating rollers 9 to rotate. The friction between the two rotating rollers 9 and the bellows 3 causes the bellows 3 to rotate. The rotating screw 14 moves on the mounting plate 2, thereby moving the stabilizing plate 13. The stabilizing plate 13 is in contact with the bellows 3 but not pressed tightly. Multiple auxiliary rollers 19 are set to assist the bellows 3 in rotating, stabilize and limit the bellows 3, and prevent the bellows 3 from deviating. The bellows 3 is not easily deviated during rotation. The electric cylinder 10 drives the connecting plate 11 and the welding machine 12 to move. The welding machine 12 contacts the bellows 3 to weld it.
[0036] 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.
