Description

Technical Field

[0001] This solution belongs to the field of welding equipment, specifically involving a composite steel pipe spiral welding device. Background Technology

[0002] Composite steel pipe is a type of pipe composed of different materials, typically consisting of an inner layer of corrosion-resistant material and an outer layer of wear-resistant material. This pipe structure combines both corrosion resistance and wear resistance, making it suitable for conveying systems in various industrial fields, such as mining, chemical, and petroleum. Composite steel pipe has high durability and stability, reducing maintenance costs and extending service life. By spiral welding, composite pipes of different diameters can be processed, and the welded composite steel pipes exhibit even greater stability. Utility model patent CN210498739U discloses a spiral welded steel pipe welding device, including a welding torch, and a first side plate and a second side plate installed at the discharge port of the forming machine roller beam; both the first and second side plates are vertically arranged and symmetrically positioned on both sides of the forming machine roller beam; the welding torch is movably positioned between the first and second side plates; a first conductive nozzle and a second conductive nozzle are spaced apart at the tip of the welding torch. The spiral welded steel pipe welding device provided by this utility model can enclose the first side plate, the second side plate, and the welding gun in the pipe blank produced from the discharge end of the forming roller beam. At this time, the welding gun is adjusted to the target position according to the spiral line of the steel pipe, and welding wire is fed into the first conductive tip and the second conductive tip respectively. After the flux is applied and the arc is submerged, double-wire welding is performed. During the welding process, the welding point tracking is adjusted at any time according to the red head of the weld to ensure the welding quality of the product.

[0003] However, when using this device, it is not convenient to clamp and fix steel pipes of different diameters and lengths. At the same time, it is not convenient to control the movement of the steel pipes for spiral welding. Utility Model Content

[0004] The purpose of this solution is to provide an adjustable welding device for solar panel installation, which solves the problems that the device is not convenient for clamping and fixing steel pipes of different diameters and lengths, and that it is inconvenient to control the movement of the steel pipes for spiral welding during use.

[0005] To achieve the above objectives, this solution provides a composite steel pipe spiral welding device, including a base, an adjustment mechanism on the base, a sliding plate on the adjustment mechanism, a slider fixedly connected to the lower end of the sliding plate, the slider and the base being slidably connected, a slide block slidably connected to the upper end of the sliding plate, a bidirectional screw threadedly connected inside the slide block, a clamping and rotating mechanism on the slide block, a bracket fixedly connected to the upper end of the base, a cylinder fixedly mounted in the middle of the bracket, the cylinder rod passing through the bracket and slidably connected to the bracket, and a welding rod fixedly connected to the lower end of the cylinder rod.

[0006] The principle of this solution is as follows: During use, according to the steel pipe length adjustment device, the bidirectional screw is manually rotated to rotate and the slide block makes a threaded movement, which in turn causes the slide block to move the support cylinder. Then, the screw cap is manually rotated, and the screw cap rotates and the support cylinder makes a threaded movement, which in turn causes the screw cap to move. The moving screw cap presses against the top plate, and the top plate moves the square rod, which in turn moves the clamping plate. The clamping plate moves and contacts the steel pipe, thus clamping and fixing the steel pipe. Then, the bidirectional screw is manually rotated to make a threaded movement, which reduces the distance between the two slide blocks, allowing the device to clamp and fix steel pipes of different lengths. By rotating the screw cap and the support cylinder to make a threaded movement, the top plate is pressed, which in turn causes the square rod to move the clamping plate, allowing the device to clamp and fix steel pipes of different diameters. Then, the motor is started, and the motor drives the screw to rotate and the pressure plate to make a threaded movement, which in turn causes the pressure plate to elastically press the connecting seat through the compression spring, which in turn causes the connecting seat to move the sliding plate, thus allowing the fixed steel pipe to move automatically during welding, making the device more convenient for spiral welding of steel pipes.

[0007] The technical advantage of this solution is that by driving the screw to rotate and the pressure plate to make a threaded motion, the pressure plate elastically squeezes the connecting seat through the compression spring, which in turn causes the connecting seat to move the sliding plate, thus making the fixed steel pipe move automatically during welding, making the device more convenient for spiral welding of steel pipes.

[0008] By rotating the screw cap and support cylinder to make threaded movements, the top plate is squeezed, which drives the square rod to move the clamping plate, allowing the device to clamp and fix steel pipes of different diameters. At the same time, by rotating the bidirectional screw and slide to make threaded movements, the distance between the two slides is reduced, allowing the device to clamp and fix steel pipes of different lengths.

[0009] Furthermore, a limiting plate is fixedly connected to the upper end of the slide plate, and the limiting plate is slidably connected to the bidirectional screw. By setting the limiting plate, the bidirectional screw is prevented from moving out of control.

[0010] Furthermore, the adjustment mechanism includes a motor. The motor is fixedly installed at the left end of the base. The output end of the motor passes through the base and is rotatably connected to it. A screw is fixedly connected to the right end of the motor's output end. A connecting seat is movably connected to the outside of the screw. The connecting seat is slidably connected to the base and fixedly connected to the sliding plate. A pressure plate is threadedly connected to the outside of the screw. The pressure plate is slidably connected to the base. A compression spring is provided on the outside of the screw. The motor drives the screw to rotate and the pressure plate to perform threaded movement, which in turn causes the pressure plate to elastically press the connecting seat through the compression spring. This causes the connecting seat to move the sliding plate, thereby allowing the fixed steel pipe to move automatically during welding, making the spiral welding of the steel pipe more convenient.

[0011] Furthermore, one end of the compression spring is fixedly connected to the connecting seat, and the other end of the compression spring is fixedly connected to the pressure plate. By setting the compression spring, the pressure plate can be easily reset.

[0012] Furthermore, the clamping and rotating mechanism includes a support cylinder. The support cylinder is mounted inside the slide block via bearings. A toothed ring is fixedly connected to the outer side of the support cylinder. A motor is fixedly mounted on the surface of the slide block, with its shaft passing through and rotatably connected to the slide block. A square rod is slidably connected inside the support cylinder. A clamping plate is fixedly connected to the lower end of the square rod, and a top plate is fixedly connected to the upper end of the square rod. A spring is provided on the outer side of the square rod. A screw cap is threadedly connected to the outer side of the support cylinder, and the screw cap is fixedly connected to the top plate. By rotating the screw cap and the support cylinder to perform threaded movement, the top plate is compressed, causing the square rod to move and the clamping plate to move. This allows the device to clamp and fix steel pipes of different diameters. Simultaneously, by rotating the bidirectional screw and the slide block to perform threaded movement, the distance between the two slide blocks is reduced, allowing the device to clamp and fix steel pipes of different lengths.

[0013] Furthermore, a gear is fixedly connected to the left end of the motor shaft, and the gear meshes with a gear ring. By setting the gear, the gear ring can be driven to rotate.

[0014] Furthermore, one end of the spring is fixedly connected to the support cylinder, and the other end of the spring is fixedly connected to the top plate. The spring facilitates the repositioning of the top plate. Attached Figure Description

[0021] The implementation examples are basically as follows Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a composite steel pipe spiral welding device, including a base 1, an adjustment mechanism 2 on the base 1, a slide plate 3 on the adjustment mechanism 2, a slider 4 fixedly connected to the lower end of the slide plate 3, the slider 4 and the base 1 being slidably connected, a slide seat 5 slidably connected to the upper end of the slide plate 3, a bidirectional screw 6 being threadedly connected inside the slide seat 5, a limit plate 7 fixedly connected to the upper end of the slide plate 3, the limit plate 7 and the bidirectional screw 6 being slidably connected, the limit plate 7 being set to prevent the bidirectional screw 6 from moving. A clamping and rotating mechanism 8 is provided on the slide seat 5, a bracket 9 is fixedly connected to the upper end of the base 1, a cylinder 10 is fixedly installed in the middle of the bracket 9, the cylinder rod of the cylinder 10 passes through the bracket 9 and is slidably connected to the bracket 9, and a welding rod 11 is fixedly connected to the lower end of the cylinder rod of the cylinder 10.

[0022] like Figure 1 , Figure 2As shown, the adjustment mechanism 2 includes a motor 21. The motor 21 is fixedly installed on the left end of the base 1. The output end of the motor 21 passes through the base 1 and is rotatably connected to the base 1. The right end of the output end of the motor 21 is fixedly connected to a screw 22. A connecting seat 23 is movably connected to the outside of the screw 22. The connecting seat 23 is slidably connected to the base 1 and fixedly connected to the slide plate 3. A pressure plate 24 is threadedly connected to the outside of the screw 22. The pressure plate 24 is slidably connected to the base 1. A compression spring 25 is provided on the outside of the screw 22. One end of the compression spring 25 is fixedly connected to the connecting seat 23, and the other end of the compression spring 25 is fixedly connected to the pressure plate 24. By providing the compression spring 25, the pressure plate 24 can be easily reset. The motor 21 drives the screw 22 to rotate and the pressure plate 24 to make threaded movements. This causes the pressure plate 24 to elastically press the connecting seat 23 through the compression spring 25, which in turn causes the connecting seat 23 to move the slide plate 3. This allows the fixed steel pipe to move automatically during welding, making the spiral welding of the steel pipe more convenient.

[0023] like Figures 1-4 As shown, the clamping and rotating mechanism 8 includes a support cylinder 81. The support cylinder 81 is mounted inside the slide block 5 via bearings. A gear ring 82 is fixedly connected to the outer side of the support cylinder 81. A motor 83 is fixedly mounted on the surface of the slide block 5. The shaft of the motor 83 passes through the slide block 5 and is rotatably connected to it. A gear 84 is fixedly connected to the left end of the shaft of the motor 83. The gear 84 meshes with the gear ring 82. By setting the gear 84, the gear ring 82 can be driven to rotate. A square rod 85 is slidably connected inside the support cylinder 81. A clamping plate 86 is fixedly connected to the lower end of the square rod 85, and a top plate 87 is fixedly connected to the upper end of the square rod 85. A spring 88 is provided on the outer side of the square rod 85. One end of the spring 88 is fixedly connected to the support cylinder 81, and the other end of the spring 88 is fixedly connected to the top plate 87. By setting the spring 88, the top plate 87 can be easily reset. The outer side of the support cylinder 81 is connected to the screw cap 89 by a thread. The screw cap 89 is fixedly connected to the top plate 87. By rotating the screw cap 89 and the support cylinder 81 to make threaded movement, the top plate 87 is squeezed, which drives the square rod 85 to move the clamping plate 86. This allows the device to clamp and fix steel pipes of different diameters. At the same time, by rotating the bidirectional screw 6 and the slide 5 to make threaded movement, the distance between the two slides 5 is reduced, allowing the device to clamp and fix steel pipes of different lengths.

[0024] The specific implementation process of this utility model is as follows: In use, according to the steel pipe length adjustment device, the bidirectional screw 6 is manually rotated to rotate and the slide 5 makes threaded movement, thereby causing the slide 5 to drive the support cylinder 81 to move. Then, the screw cap 89 is manually rotated, and the screw cap 89 rotates and makes threaded movement with the support cylinder 81, thereby causing the screw cap 89 to move. The screw cap 89 moves and presses against the top plate 87. The top plate 87 drives the square rod 85 to move, and the square rod 85 drives the clamping plate 86 to move. The clamping plate 86 moves and contacts the steel pipe, thereby clamping and fixing the steel pipe. Then, the bidirectional screw 6 and the slide 5 are manually rotated to make threaded movement, thereby increasing the distance between the two slides 5. The size reduction allows the device to clamp and fix steel pipes of different lengths. By rotating the screw cap 89 and the support cylinder 81 to make threaded movements, the top plate 87 is squeezed, which drives the square rod 85 to move the clamping plate 86. This allows the device to clamp and fix steel pipes of different diameters. Then, the motor 21 is started, which drives the screw 22 to rotate and the pressure plate 24 to make threaded movements. This causes the pressure plate 24 to elastically squeeze the connecting seat 23 through the compression spring 25. This causes the connecting seat 23 to move the sliding plate 3, which in turn causes the fixed steel pipe to move automatically during welding. This makes the device more convenient for spiral welding of steel pipes.

[0025] The motor 21 drives the screw 22 to rotate and the pressure plate 24 to make a threaded movement. This causes the pressure plate 24 to elastically press the connecting seat 23 through the compression spring 25, which in turn causes the connecting seat 23 to move the sliding plate 3. This allows the fixed steel pipe to move automatically during welding, making the spiral welding of the steel pipe more convenient.

[0026] By rotating the screw cap 89 and the support cylinder 81 to make threaded movements, the top plate 87 is squeezed, which drives the square rod 85 to move the clamping plate 86, so that the device can clamp and fix steel pipes of different diameters. At the same time, by rotating the bidirectional screw 6 and the slide 5 to make threaded movements, the distance between the two slides 5 is reduced, so that the device can clamp and fix steel pipes of different lengths.
