Description

Technical Field

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

[0002] A bellows is a pipe used to transport fluids, gases, or other substances. It consists of a series of corrugated folds, which give the pipe a certain degree of flexibility and extensibility. Bellows are widely used in building construction, factory production, and instrumentation. Their main purpose is as a measuring element in pressure measuring instruments. They are elastic and convert pressure into displacement or force.

[0003] Corrugated pipe welding is the process of connecting corrugated pipes together. During the installation and use of corrugated pipes, it is sometimes necessary to connect multiple sections of corrugated pipes to form a continuous pipeline system. However, the current equipment has poor stability of corrugated pipes when welding them, making it difficult to adjust and position them for different sizes of corrugated pipes, which is inconvenient for welding.

[0004] A search revealed a utility model patent with Chinese patent publication number CN117182439A: a clamping and positioning device for corrugated pipe welding, including an operating plate, with support legs fixedly connected to the four corners of the lower surface of the operating plate, a sliding groove in the middle of the upper surface of the operating plate, adjustment mechanisms on the left and right sides above the operating plate, and a cooling mechanism on the back of the operating plate.

[0005] However, existing technical solutions still have the problem of not being able to rotate the bellows. When it is necessary to change the welding point, the bellows needs to be picked up and placed again, which reduces work efficiency and has poor practicality. Therefore, a bellows welding fixture is needed to improve the above problems. Utility Model Content

Four second electric push rods are symmetrically fixedly installed on each of the two placement plates. The other end of each second electric push rod is fixedly connected to the corresponding rotating plate.

[0011] Both placement plates are equipped with limit components. One of the limit components includes a pressure plate that is slidably connected to the placement plate. A first screw is rotatably mounted on the pressure plate and screwed onto the placement plate.

[0012] The platform is equipped with a moving mechanism, which includes a second motor. A slide groove is provided on the platform.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a corrugated pipe welding fixture, which has the following advantages:

[0020] Two corrugated pipes to be welded are passed through two support plates and placed on two placement plates. Rotating the two first screws moves the two pressure plates, which limit the position of the corrugated pipes. A dual-axis motor is activated, driving two rotating shafts to rotate, which in turn rotates the two first and second transmission wheels. These wheels, in conjunction with the second transmission wheels, drive the two second transmission wheels, which in turn rotate the two rotating plates, causing the two placement plates to rotate the two corrugated pipes. This combination of welding equipment and the pipes allows for more uniform, comprehensive, and effective welding. When the welding point needs to be moved or replaced, a second motor is activated, driving a second screw to rotate, which moves a slider along the screw. This slider allows for easy adjustment of the welded pipe's position. Finally, a first electric push rod is activated, moving a connecting plate to adjust the position of the welded pipe.

[0027] Example

[0028] Please see Figure 1-3 A corrugated pipe welding fixture includes a platform 1, two support plates are symmetrically fixedly installed on the top of the platform 1, two fixed plates 2 are symmetrically fixedly installed on the platform 1, and a rotating plate 3 is rotatably installed on each of the two fixed plates 2.

[0029] Please see Figure 1-3 Platform 1 is equipped with a positioning mechanism, which includes two placement plates 8. The two corrugated pipes to be welded are passed through the two support plates and placed on the two placement plates 8. A dual-axis motor 4 is fixedly installed at the bottom of platform 1. Two rotating shafts 5 are symmetrically fixedly installed at the two output ends of the dual-axis motor 4. A first conveyor wheel 6 is fixedly installed on each of the two rotating shafts 5. A second conveyor wheel 7 is fixedly installed on each of the two rotating plates 3. The first conveyor wheel 6 and the second conveyor wheel 7 on the same side are connected by a tensioned conveyor belt. Four second electric push rods 27 are symmetrically fixedly installed on each of the two placement plates 8. The other end of each second electric push rod 27 is fixedly connected to the corresponding rotating plate 3. When the dual-axis motor 4 is started, it drives the two rotating shafts 5 to rotate, thereby rotating the two first conveyor wheels 6. Through the cooperation of the two first conveyor wheels 6 and the two second conveyor wheels 7, the two first conveyor wheels 6 drive the two second conveyor wheels 7, which in turn drive the two rotating plates 3 to rotate, thereby causing the two placement plates 8 to drive the two corrugated pipes to rotate.

[0030] Please see Figure 1-4 Both placement plates 8 are equipped with limiting components. One of the limiting components includes a pressure plate 9, which is slidably connected to the placement plate 8. A first screw 10 is rotatably mounted on the pressure plate 9 and screwed onto the placement plate 8. By rotating the two first screws 10, the two first screws 10 drive the two pressure plates 9 to move, thereby limiting the corrugated pipe through the two pressure plates 9.

[0031] Please see Figure 1 and Figure 2A moving mechanism is provided on platform 1, including a second motor 11. A slide groove is provided on platform 1. A second screw 12 is fixedly installed at the output end of the second motor 11. The second screw 12 is rotatably connected to the slide groove. A slider 13 is screwed onto the second screw 12 and is slidably connected to the slide groove. A welding device 14 is fixedly installed on platform 1. A welding pipe 15 is connected to the welding device 14. The corrugated pipe is welded by the cooperation of the welding device 14 and the welding pipe 15, so that the welding operation is more uniform, comprehensive and effective. The welding pipe 15 is slidably connected to the slider 13. A connecting plate 16 is fixedly installed on the 15, and a first electric push rod 17 is fixedly installed on the connecting plate 16. The first electric push rod 17 is fixedly connected to the slider 13. When it is necessary to replace or move the welding point, the second motor 11 is started, and the second motor 11 drives the second screw 12 to rotate, thereby moving the slider 13 on the second screw 12. The position of the welding tube 15 can be easily adjusted through the slider 13. The first electric push rod 17 is started, and the first electric push rod 17 drives the connecting plate 16 to move, thereby adjusting the position of the welding tube 15 through the connecting plate 16.

[0032] Please see Figure 1-4 The two rotating plates 3 are stabilized and limited by corresponding limiting components. One of the limiting components includes a slide rod 19. A slide rail 18 is provided on the fixed plate 2. The slide rail 18 is slidably connected to the slide rod 19. The cooperation between the slide rod 19 and the slide rail 18 makes the rotating plate 3 more stable when rotating.

[0033] Please see Figure 1-4 Rubber pads 20 are fixedly installed on both placement plates 8. The setting of two rubber pads 20 increases the friction and makes the corrugated pipe more stable.

[0034] Please see Figure 1 and Figure 2 It should also be noted that protective shells 21 are fixedly installed on both fixed plates 2. The first conveyor wheel 6 and the second conveyor wheel 7 on the same side are located inside the corresponding protective shells 21. The two protective shells 21 protect the two first conveyor wheels 6 and the two second conveyor wheels 7 and extend their service life.

[0035] Please see Figure 2 A support plate 22 is fixedly installed at the bottom of the platform 1. The dual-axis motor 4 is fixedly connected to the support plate 22. The support plate 22 supports the dual-axis motor 4, making the dual-axis motor 4 more stable.

[0036] In summary, when using this corrugated pipe welding fixture, the two corrugated pipes to be welded are passed through the two support plates and placed on the two placement plates 8. Multiple second electric push rods 27 are activated to adjust the position of the two placement plates 8. The two first screws 10 are rotated, causing the two first screws 10 to move the two pressure plates 9, which limit the movement of the corrugated pipes. The welding equipment 14 is then activated, and the corrugated pipes are welded through the cooperation of the welding equipment 14 and the welding pipe 15. The dual-axis motor 4 is activated, driving the two rotating shafts 5 to rotate, thereby rotating the two first conveyor wheels 6. One first conveyor wheel 6 and two second conveyor wheels 7 work together to drive the two second conveyor wheels 7, which in turn drive the two rotating plates 3 to rotate, which in turn drive the two placement plates 8 to rotate the two corrugated pipes, making the welding operation more uniform, comprehensive and effective. When it is necessary to change or move the welding point, the second motor 11 is started, which drives the second screw 12 to rotate, thereby moving the slider 13 on the second screw 12. The slider 13 facilitates the adjustment of the position of the welding pipe 15. The first electric push rod 17 is started, which drives the connecting plate 16 to move, and the position of the welding pipe 15 is adjusted through the connecting plate 16.
