Description

Technical Field

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

[0002] A bellows is a tubular elastic sensing element composed of foldable corrugated sheets interconnected along its expansion and contraction direction. This unique structural design gives it excellent flexibility and extensibility. In the instrumentation industry, bellows have a wide range of applications and are crucial. They are primarily used as the core measuring component of various pressure measuring instruments, accurately converting received pressure signals into measurable displacement or force. In the manufacturing process of bellows, welding is a critical step. Specialized welding techniques are required to firmly connect the bellows body to various joints, which not only affects the product's sealing performance but also directly impacts the accuracy and reliability of the entire measurement system.

[0003] For example, patent number CN 220163272 U discloses a fixing device for corrugated pipe welding, including a platform. Support plates are symmetrically fixedly installed on the left and right sides of the upper end of the platform. Electric telescopic rods are symmetrically fixedly installed on the upper sides of the two support plates that are close to each other. A housing is fixedly installed on the movable end of each of the two electric telescopic rods. This fixing device for corrugated pipe welding includes an auxiliary device for guiding and aligning two corrugated pipes. Using reference markings on a reference plate, the welding surfaces of the two placed corrugated pipes can be aligned. During welding, the welding surfaces are precisely aligned. Then, the threaded rod is rotated to push the arc-shaped clamping plate downwards, clamping and fixing the corrugated pipes. This ensures that the cross-sections of the two corrugated pipes are aligned during welding, preventing misalignment of the welding surfaces due to positional deviations, and providing a reliable guarantee for the welding quality of the corrugated pipes.

[0004] For example, patent number CN 219852989 U discloses a corrugated pipe welding and fixing device, including a base plate, a first side plate and a second side plate fixedly connected to the top surface of the base plate, a fixing assembly and a guide rod rotatably connected to the outer surface of the first side plate, and a reduction motor installed on the back of the first side plate. The outer surface of the guide rod is slidably connected to a third side plate, and a cylinder is fixedly connected to the back of the third side plate. This invention places the corrugated pipe to be welded between two clamping plates. When the handwheel is turned clockwise, the two sliders move closer together, thereby causing the two clamping plates to move closer together. The two clamping plates can then hold the corrugated pipe in place. Because the two sliders drive the two clamping plates to move synchronously, the corrugated pipe is fixed and aligned with the rotating shaft on the same axis. Thus, the two sets of fixing assemblies can fix two corrugated pipes or one corrugated pipe and one connector, ensuring accurate alignment of the corrugated pipes during welding and preventing misalignment.

[0005] The first patent uses two sleeves and two arc-shaped clamps to fix two bellows respectively, and uses a motor to control the distance between them to fix the bellows. The second patent uses two fixing components to fix two bellows respectively. Although both patents can fix the bellows, they cannot effectively fix the bellows when the bellows are too long, and both require a motor to control the distance between the two bellows. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a corrugated pipe welding and fixing device, which solves the problems in the above two patents, such as the inability to effectively fix the corrugated pipe when it is too long, and the need for a motor to control the distance between the two corrugated pipes, which leads to complex control and increased costs.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a corrugated pipe welding and fixing device, comprising a housing, a clamping plate inside the housing, a positioning rod positioning mechanism at the rear of the housing, a disc body inside the clamping plate, four vertical guide columns inside the disc body, a moving block on each vertical guide column, a clamping plate at the right end of each moving block, a clamping pad below the clamping plate, a guide block at the left end of each moving block, a horizontal guide column inside the disc body, a guide block on each horizontal guide column, a gear disk connected to the guide block, and a control disk at the left end of the gear disk.

[0008] Preferably, the housing is provided with a base, a baffle is provided at the left end of the base, and a support is provided at the right end of the base.

[0009] Preferably, a control lever is provided at the rear of the base, a gear is provided at the left end of the control lever, the gear meshes with the control disk, and a rotating disk is provided at the right end of the control lever.

[0010] Preferably, the baffle is provided with three screws, each screw is provided with a positioning clamp, and the positioning clamp is provided with a positioning pad.

[0011] Preferably, the positioning pad is connected to the positioning rod, the positioning rod is provided with a baffle, the surface of the positioning rod is treated with surface carburizing process, which has good high temperature resistance, and the positioning rod can be replaced with positioning rods of different diameters to adapt to corrugated pipes of different diameters.

[0012] (III) Beneficial Effects This utility model provides a corrugated pipe welding and fixing device. It has the following beneficial effects: It can effectively solve the problem of fixing long corrugated pipes. Traditional devices are not effective at fixing long corrugated pipes, but this device, through the coordinated action of components such as the clamping plate, positioning rod positioning mechanism, and base, can stably support and fix long corrugated pipes from multiple angles, ensuring that the corrugated pipes will not shake or shift during the welding process, thus improving the stability and accuracy of welding.

[0013] It is easy to operate, requiring no motor to control the distance between the two bellows. Through manual operation components such as the control panel and rotary control panel, operators can easily adjust the position of the clamp and the distance between the two bellows, reducing control complexity and minimizing maintenance costs and downtime due to motor failures, thus improving production efficiency.

[0014] It is highly versatile and applicable to the welding of bellows of different specifications. The clamping plates of the chuck, the positioning clamping plates of the positioning rod positioning mechanism, and the replacement positioning rods can all be flexibly adjusted according to the size of the bellows.

[0015] This device is based on an improvement of existing equipment, so the improvement cost is relatively low and it will not cause a large amount of existing equipment to be discarded. It ensures the processing effect while reducing the investment in improvement costs, making it suitable for large-scale production. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-6 This utility model provides a technical solution: a corrugated pipe welding and fixing device, including a housing 1, a base 11 provided on the housing 1, a control rod 14 provided behind the base 11, a gear 16 provided on the left end of the control rod 14, the gear 16 meshing with a control disk 28, a rotating disk 15 provided on the right end of the control rod 14, a baffle 13 provided on the left end of the base 11, three screws 34 provided on the baffle 13, a positioning clamp 33 provided on the screws 34, a positioning pad 32 provided on the positioning clamp 33, the positioning pad 32 connected to a positioning rod 31, a baffle 35 provided on the positioning rod 31, the surface of the positioning rod 31 is treated with surface carburizing process, which has good high temperature resistance, and the positioning rod 31 can be replaced with positioning rods of different diameters to adapt to corrugated pipes of different diameters. The base 11 has a support platform 12 at its right end. The housing 1 has a clamping plate 2 inside. The housing 1 has a positioning rod positioning mechanism 3 at its rear. The clamping plate 2 has a disc body 21. The disc body 21 has four vertical guide columns 22 inside. The vertical guide columns 22 have moving blocks 23. The right end of the moving block 23 has a clamping plate 24. The clamping pad 25 is located below the clamping plate 24. The left end of the moving block 23 has a guide block 26. The disc body 21 has a horizontal guide column 29 inside. The guide block 26 is located on the horizontal guide column 29. The guide block 26 is connected to a gear disk 27. The left end of the gear disk 27 has a control disk 28.

[0019] In use, first select a suitable positioning rod 31 according to the diameter of the corrugated pipe to be welded. After selection, extend the positioning rod 31 from the back of the device. After extending it to a certain position, rotate the rotating disk 15. The rotating disk 15 drives the gear 16 to rotate through the control rod 14. The rotation of the gear 16 drives the gear disk 27 to rotate. The rotation of the gear disk 27 drives the guide block 26 to move. Since the guide block 26 and the moving block 23 mesh with each other, when the gear disk 27 rotates counterclockwise, the four moving blocks 23 will be pushed outward by the four guide blocks 26, causing the clamping plate 24 to open. Conversely, it will close. After the four clamping plates 24 fix the positioning rod 31, use a tool to rotate the three screws 34 to move the three positioning clamping plates 33 inward, so that they clamp the positioning rod 31. The positioning rod 31 is held in place. When the device is stationary, the four clamping plates 24 are moved outwards to release the positioning rod 31, thus fixing the positioning rod 31 in place. Then, a corrugated pipe to be welded is placed over the positioning rod 31 from front to back. Since the corrugated pipe's length exceeds the positioning rod 31, it can be pushed to the left. Due to the presence of the baffle 35, the left side of the corrugated pipe remains stationary while the right side moves to the left, compressing the corrugated pipe and shortening its overall length. Then, the rotating disk 15 is rotated again, causing the four clamping plates 24 to move inwards to clamp the corrugated pipe, keeping it compressed. After one end of the corrugated pipe is installed, the second corrugated pipe is placed over the positioning rod 31 again, so that the right end of the first compressed corrugated pipe and the left end of the second corrugated pipe are naturally aligned under the action of the positioning rod 31. During welding, because the surface of the positioning rod 31 has undergone carburizing treatment, the positioning rod 31 will not fuse with the corrugated pipe.

[0020] In summary, this bellows welding and fixing device achieves precise connection of two bellows through the clamp 2 and positioning rod 31. It is highly versatile, easy to operate, and applicable to the welding of bellows of different specifications. It reduces the complexity of control, and also reduces maintenance costs and downtime caused by motor failure, thereby improving production efficiency.
