[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a steel pipe joint welding mechanism, which solves the problem that steel pipe joint welding mechanisms can usually only perform circumferential joint welding, and require different machines to perform longitudinal joint welding, thereby reducing production costs.

[0027] like Figure 1-7 As shown, this utility model discloses a steel pipe joint welding mechanism, comprising a support plate 1. A movable block 2 is connected to the surface of the support plate 1 via a sliding groove 21. A support plate 3 is welded to the top of the movable block 2. A turntable 4 is mounted on the surface of the support plate 3. A U-shaped plate 5 is connected to the surface of the turntable 4 via a rotating shaft. An electric push rod 6 is mounted on the surface of the U-shaped plate 5. A clamping plate 8 is fixedly connected to the surface of the electric push rod 6. A steel pipe 7 is attached to the surface of the clamping plate 8. An L-shaped plate 9 is welded to the surface of the movable block 2. A first hand-tightening bolt 10 is threadedly connected to the surface of the L-shaped plate 9. A first ear plate 11 is welded to the surface of the support plate 3. A second hand-tightening bolt 12 is threadedly connected to the surface of the first ear plate 11. A baffle 13 is welded to the surface of the support plate 3. Thus, when performing joint welding on the steel pipe 7, the steel pipe 7 is placed on the placement plate 32, initially stabilizing the steel pipe. Pipe 7 is clamped by starting the electric push rod 6, which drives the clamping plate 8 to prevent the steel pipe 7 from shaking and affecting the welding effect, thus increasing the stability of the device. Then, by rotating the bidirectional hand-tightening threaded rod 31, the sliders at both ends can be moved towards the center, so that the two steel pipes 7 are in circumferential contact for circumferential welding. When it is necessary to switch to longitudinal welding, first loosen the first hand-tightening bolt 10, and then rotate the U-shaped plate 5 connected to the turntable 4 through the rotating shaft until its surface is in contact with the support plate 3. Then, rotate the U-shaped plate 5 in plane so that it rotates around the turntable 4 until the surface of the U-shaped plate 5 is in contact with the baffle 13. Then, rotate the second hand-tightening bolt 12 to press the U-shaped plate 5 to fix it. At this time, the steel pipes 7 at both ends are in longitudinal contact when they are in contact by the bidirectional hand-tightening threaded rod 31, and longitudinal welding can be performed.

[0028] A slot 14 is provided on the surface of the support plate 1. A plug block 15 is inserted into the inside of the slot 14. A mounting bracket 16 is welded to the surface of the plug block 15. A rotating cylinder 17 is connected to the surface of the mounting bracket 16 via a bearing. A ring gear 18 is fixedly connected to the surface of the rotating cylinder 17. A gear 19 is meshed with the surface of the ring gear 18. A motor unit 20 is connected to the surface of the gear 19 via a rotating rod. A sliding groove 21 is provided on the surface of the rotating cylinder 17. A sliding sleeve 22 is slidably connected to the inside of the sliding groove 21. A fixing rod 25 is welded to the surface of the sliding sleeve 22. A first fixing plate 26 penetrates the surface of the fixing rod 25. The fixing rod 25 is connected to the surface of the first fixing plate 26 via a spring. A movable rod 23 is inserted into the inside of the sliding sleeve 22. The sliding sleeve 22 is connected to the surface of the movable rod 23 via a spring. The other end of 23 is fixedly connected to a double-sided grinding plate 24. As the steel pipe 7 moves towards the center by rotating the bidirectional hand-tightening bolt, the welded area on its surface will first enter the inner side of the rotating drum 17. Then, the movable rod 23 is pulled. As it continues to move towards the center, the annular surface will first be polished by the double-sided grinding plate 24. At this time, the movable rod 23 is released. Under the action of the compression spring, the movable rod 23 will drive the double-sided grinding plate 24 to press against the cylindrical surface of the steel pipe 7. After moving forward a certain distance, the sliding sleeve 22 is pushed to move in the sliding groove 21. At this time, the surface of the sliding sleeve 22 will drive the double-sided grinding plate 24 to press against the annular surface of the steel pipe 7 under the action of the compression spring, realizing self-adaptive grinding. In this way, the welded area is polished on both sides to avoid the dust or rust on the surface from affecting the welding effect.

[0029] The mounting bracket 16 has a second fixing plate 27 welded to its bottom. The surface of the second fixing plate 27 is connected to a fixing bolt 28 by thread. The surface of the fixing bolt 28 is connected to a third fixing plate 29 by thread. The surface of the third fixing plate 29 is welded to a support plate 1. In this way, when switching the longitudinal seam welding, the mounting bracket 16 can be disassembled simply by unscrewing the fixing bolt 28, which avoids affecting the longitudinal seam welding and increases the rationality of the device.

[0030] A second ear plate 30 is welded to the surface of the support plate 1. A two-way hand-tightening threaded rod 31 is connected to the surface of the second ear plate 30 via a bearing. A movable block 2 is connected to the surface of the two-way hand-tightening threaded rod 31 via a thread. By rotating the two-way hand-tightening threaded rod 31, the movable block 2 can be made to move the steel pipe 7 clamped by the two clamping plates 8 towards the center at the same time, which increases the convenience of the device.

[0031] A placement plate 32 is fixedly connected to the surface of the U-shaped plate 5. There are two placement plates 32. By placing the steel pipe 7, the steel pipe 7 can be initially stabilized and prevented from sliding when clamped by the clamping plate 8, thus increasing the practicality of the device.

[0032] A base plate 33 is welded to the bottom of the support plate 1, and an anti-slip pad 34 is glued to the bottom of the base plate 33. The anti-slip pad 34 at the bottom of the base plate 33 increases the friction coefficient between the device and the ground, prevents it from shaking, and increases the stability of the device.

[0033] Combination Figures 1-7 The specific usage process of the steel pipe seam welding mechanism in this embodiment is as follows: When performing seam welding on the steel pipe 7, the steel pipe 7 is placed on the placement plate 32 to initially stabilize the steel pipe 7. Then, the electric push rod 6 is activated to drive the clamping plate 8 to clamp the steel pipe 7, preventing the steel pipe 7 from shaking and affecting the welding effect, thus increasing the stability of the device. Then, by rotating the bidirectional hand-tightened threaded rod 31, the sliders at both ends can be moved towards the center, so that the two steel pipes 7 are in circumferential contact for circumferential seam welding. When it is necessary to switch to longitudinal seam welding, first loosen the first hand-tightened bolt 10, and then rotate the U-shaped plate 5 connected to the turntable 4 through the rotating shaft until its surface is in contact with the support plate 3. Then, rotate the U-shaped plate 5 in plane so that it rotates around the turntable 4 until the surface of the U-shaped plate 5 is in contact with the baffle 13. Then, rotate the second hand-tightened bolt 12 to press the U-shaped plate 5 to play a fixing role. At this time, the steel pipes 7 at both ends are in longitudinal contact when they are in contact by the bidirectional hand-tightened threaded rod 31, and longitudinal seam welding can be performed.

[0034] In this embodiment, since the surface of the steel pipe 7 may contain a lot of dust or rust during welding, which may affect the welding effect, please refer to the following again. Figures 1-7 In this embodiment, when the steel pipe 7 is being circumferentially welded, after the steel pipe 7 is fixed by the clamping plate 8, the steel pipe 7 is moved towards the center by rotating the double-sided hand-tightening bolt. The weld joint on its surface will first enter the inner side of the rotating drum 17. Then, the movable rod 23 is pulled. As it continues to move towards the center, the circumferential surface will first be polished by the double-sided grinding plate 24. At this time, the movable rod 23 is released. Under the action of the compression spring, the movable rod 23 will drive the double-sided grinding plate 24 to press against the cylindrical surface of the steel pipe 7. After moving forward a certain distance, the sliding sleeve 22 is pushed to move in the sliding groove 21. At this time, the surface of the sliding sleeve 22 will drive the double-sided grinding plate 24 to press against the circumferential surface of the steel pipe 7 under the action of the compression spring, realizing adaptive grinding. In this way, the weld joint is polished on both sides to avoid the dust or rust on the surface from affecting the welding effect.
