[0015] As a further description of the above technical solution: A grinding piece is fixedly installed at the middle position of the outer surface of the arc-shaped protective cover, mounting openings are arranged on the two sides of the middle portion of the grinding piece, and a weld treatment roller is rotatably installed on the inner side of the mounting opening through a rotating shaft.

[0016] As described above, due to the adoption of the above technical solution, the beneficial effects of the present application are: 1. In this invention, two movable components are provided. When welding two sets of steel pipes, the two sets of steel pipes are first installed on the movable components, and then the steel pipes are directly fitted onto the outside of the steel pipe positioning mechanism. The pneumatic rod can be automatically shortened, thereby pulling back the third mounting sleeve connected at one end. When the third mounting sleeve is pulled back, multiple intelligent internal support positioning components are controlled to move outward through the first and second connecting parts until the multiple intelligent internal support positioning components contact and compress the inner wall of the steel pipe, thus completing the rapid positioning of the steel pipe. During the positioning process, if there is a protruding structure or deformation on the inner wall of the steel pipe, since the multiple intelligent internal support positioning components are designed in a coordinated manner, when one of them... After several intelligent internal support positioning components come into contact with the protruding areas of the inner wall of the steel pipe, the other intelligent internal support positioning components will inevitably not be able to fully conform to the other flat inner walls of the steel pipe. At this time, the pressure monitoring plate inside the intelligent internal support positioning components that are not fully conformed to the inner wall of the steel pipe will reduce or fail to detect pressure. At this point, the two sets of fixed-point support electric actuators can be activated, allowing them to contact the inner wall of the steel pipe for support. The drive motor then starts, controlling the rotation of the grinding roller to grind the protruding structure inside the steel pipe, eliminating the protrusion until the inner contact surface of the grinding roller with the steel pipe is flush with the other areas. At this point, the other intelligent internal support positioning components can also stably conform to the inner wall of the steel pipe. This design provides more stable support for the steel pipe. After positioning, the adjusting motor automatically starts, driving the bidirectional threaded shaft to rotate. The bidirectional threaded shaft can control two moving components on it to move closer to each other until the two ends of the steel pipe to be welded are joined. The extension and descent welding module automatically controls its descent to automatically weld the joint between the two steel pipes. During this process, the rotary motor can automatically start, driving the steel pipe positioning mechanism to rotate slowly and synchronously with the externally positioned steel pipe. At this time, the extension and descent welding module can complete the all-round circumferential welding of the steel pipe. After welding is completed, the positioning effect of the steel pipe positioning mechanism is released, and the moving components can be removed to both sides to quickly remove the welded steel pipe. Through this design, the internal support of the steel pipe can be quickly achieved. Compared to external positioning, this positioning method offers a more effective and stable positioning effect, and can position steel pipes of completely different specifications without affecting external operations or causing damage to the outer surface of the steel pipe. Furthermore, during the internal support positioning of the steel pipe, the equipment automatically monitors and processes protruding areas on the inner wall of the steel pipe, ensuring that each positioning structure fits tightly against and is compressed against the inner wall of the steel pipe, further improving the positioning effect. The butt-joint rotary welding method improves the overall welding coverage, eliminating dead angles and guaranteeing welding quality. The processed steel pipe can be quickly removed after welding. The equipment operates fully automatically, requiring no manual management, and has excellent application results.

[0017] 2. In this invention, a welding protection mechanism is provided inside. When the moving components approach each other and drive the steel pipes to be connected, the side extrusion rod can also move synchronously and press the locking block, causing the locking block to retract into the bottom shell. At this time, the built-in spring controls the telescopic seat to spring up, and the arc-shaped protective cover moves upward synchronously until the grinding disc is in contact with the joint of the two steel pipes. Before actual welding, the steel pipe positioning mechanism can be driven to rotate, causing the two steel pipes to rotate synchronously. During this process, the grinding disc can automatically grind the joint of the two steel pipes and clean the surface impurities at the joint of the steel pipes. Through this design, the welding protection mechanism can be driven to be extended while driving the two steel pipes to be connected, and the pretreatment of the steel pipes can be achieved, avoiding the influence of impurities in the welding area of ​​the steel pipes on the welding effect.

[0018] 3. In this invention, by designing the welding protection mechanism to be rotatable, during actual welding, the external motor can control the arc-shaped protective cover to rotate 180°. At this time, the concave surface of the arc-shaped protective cover is directly facing the joint area of ​​the two steel pipes, and the two sets of weld seam treatment rollers can contact the joint of the steel pipes. At this time, the steel pipe is controlled to rotate for welding. The high temperature generated during welding is conducted downward and radiated to the welding center area by the heat radiation coating, which can keep the welding center area at a high temperature, which is conducive to the formation of the weld and improves the welding quality. At the same time, as the steel pipe rotates, the weld seam treatment rollers can continuously roll in the welding area of ​​the steel pipe to achieve synchronous flattening treatment of the weld, which greatly improves the welding effect of the steel pipe and improves the actual application effect of the equipment.

[0031] Please see Figures 1-6 and Figures 9-10 The present invention provides a technical solution: an automated steel pipe processing device, including a telescopic welding module 1 and a base 4. A side shell 3 is provided on the top surface of the base 4, a top plate 2 is installed on the side wall of the side shell 3, the telescopic welding module 1 is provided on the top plate 2, a stroke groove 5 and an installation groove 10 are provided on the top surface of the base 4, and a controller 9 is provided on one outer wall of the top plate 2. The mounting slot 10 is equipped with a welding protection mechanism 8 for pretreatment before welding and heat protection during welding. An adjustment motor 7 is fixedly installed on one side of the outer wall of the base 4. A bidirectional threaded shaft 11 is fixedly installed at one end of the output shaft of the adjustment motor 7. Two moving components 6 are movably installed on the outside of the bidirectional threaded shaft 11. Both moving components 6 are used for the rapid assembly and positioning of the welded steel pipe.

[0032] The movable component 6 includes a mounting bracket 62, which is slidably mounted in the stroke groove 5. A rotary motor 61 is fixedly mounted on one outer wall of the mounting bracket 62, and a side compression rod 63 is fixedly mounted on the other outer wall of the mounting bracket 62. A bushing 65 is provided on the mounting bracket 62. A bidirectional threaded shaft 11 is threadedly connected to a threaded hole provided inside the mounting bracket 62. A main shaft 66 is provided at one end of the output shaft of the rotary motor 61, and a steel pipe positioning mechanism 64 is provided on the outside of the main shaft 66.

[0033] The steel pipe positioning mechanism 64 includes a first mounting sleeve 641 and a second mounting sleeve 645, both of which are fixedly mounted on the outside of the main shaft 66. Multiple intelligent internal support positioning components 642 are connected to the outside of both the first and second mounting sleeves 641 and 645 via a first connector 643. A pneumatic rod 644 is provided on one outer wall of the second mounting sleeve 645, and a third mounting sleeve 646 is provided at one end of the pneumatic rod 644. The third mounting sleeve 646 is fitted onto the outside of the main shaft 66 and is connected to the intelligent internal support positioning components 642 via a second connector 647. The active connection, the intelligent internal support positioning component 642 includes an internal support positioning frame 6427, the internal support positioning frame 6427 is provided with an assembly groove 6426, the assembly groove 6426 is T-shaped, a pressure monitoring plate 6422 is provided on the inner wall of the bottom surface of the assembly groove 6426, two sets of fixed-point support electric push rods 6421 and assembly frame 6425 are fixedly installed on the top surface of the pressure monitoring plate 6422, a drive motor 6424 is fixedly installed inside the assembly frame 6425, a grinding roller 6423 is fixedly installed at one end of the output shaft of the drive motor 6424, and the monitoring data of the pressure monitoring plate 6422 is transmitted to the controller 9.

[0034] Furthermore, during the welding of the two sets of steel pipes, the two sets of steel pipes are first installed on the moving component 6, and then the steel pipes are directly fitted onto the outside of the steel pipe positioning mechanism 64. The pneumatic rod 644 can be automatically shortened, thereby pulling back the third mounting sleeve 646 connected at one end. When the third mounting sleeve 646 is pulled back, the first connecting piece 643 and the second connecting piece 647 control multiple intelligent internal support positioning components 642 to move outward until the multiple intelligent internal support positioning components 642 contact and press against the inner wall of the steel pipe, thus completing the rapid positioning of the steel pipe. During the positioning process, if there are protruding structures or deformations on the inner wall of the steel pipe, because the multiple intelligent internal support positioning components 642 are designed in conjunction, when one or more intelligent internal support positioning components 642 come into contact with the protruding area of ​​the inner wall of the steel pipe, the other intelligent internal support positioning components 642 will inevitably not be able to fully fit against the other flat inner walls of the steel pipe. At this time, the pressure monitoring plate 6422 inside the intelligent internal support positioning component 642 that is not fully fitted against the inner wall of the steel pipe will reduce or fail to detect pressure. In this case, the two sets of fixed-point support electric actuators 6421 can be controlled to open. Two sets of fixed-point support electric actuators 6421 can contact the inner wall of the steel pipe for support. The drive motor 6424 starts to control the rotation of the grinding roller 6423, which grinds and eliminates the protruding structure inside the steel pipe until the inner contact surface of the grinding roller 6423 is flush with other areas. At this time, the other multiple intelligent internal support positioning components 642 can also stably fit against the inner wall of the steel pipe, providing a more stable support effect for the steel pipe. After positioning, the adjusting motor 7 automatically starts, driving the bidirectional threaded shaft 11 to rotate. The bidirectional threaded shaft 11 can control the two moving components 6 on it to approach each other until the two ends of the steel pipe to be welded are joined. The extension and descent welding module 1 is automatically controlled to descend and automatically weld the joint of the two steel pipes. During this process, the rotary motor 61 can be automatically turned on, driving the steel pipe positioning mechanism 64 to rotate slowly and synchronously with the steel pipe positioned outside it. At this time, the extension and descent welding module 1 can complete the all-round circumferential welding of the steel pipe. After the welding is completed, the positioning effect of the steel pipe positioning mechanism 64 is released, and the moving components 6 can be removed to both sides to quickly remove the welded steel pipe.

[0035] This design enables rapid internal support positioning of steel pipes, providing a more effective and stable positioning effect compared to external positioning. It can also position steel pipes of completely different specifications without affecting external operations. Furthermore, the butt-joint rotary welding method improves the overall welding coverage, ensuring no dead corners in the welding area and guaranteeing the welding effect. The processed steel pipe can be quickly removed after welding. The equipment operates fully automatically without manual management, resulting in excellent application performance.

[0036] Please see Figure 7 and Figure 8The welding protection mechanism 8 includes a base shell 84, which is located inside the mounting groove 10. A telescopic seat 82 is movably installed inside the base shell 84 via a built-in spring 88. An inner groove 86 is provided on both outer walls of the telescopic seat 82. A locking block 87 is movably installed inside the inner groove 86 via a compression spring. A side groove 83 is provided on both outer walls of the base shell 84. One end of the locking block 87 passes through the side groove 83 and extends to the outside of the base shell 84. A side compression rod 63 is located on one side of the locking block 87.

[0037] Two top frames 85 are fixedly installed on the top surface of the telescopic seat 82. A welding protection component 81 is provided between the two top frames 85. The welding protection component 81 includes an external motor 813, which is fixedly installed on one side of the outer wall of the top frame 85.

[0038] An external motor 813 has a side shaft 815 at one end of its output shaft. An arc-shaped protective cover 812 is fixedly installed on the outer side of the side shaft 815 through an inner frame 814. A heat radiation coating 818 is provided on the inner surface of the arc-shaped protective cover 812.

[0039] Furthermore, during the actual welding process, the external motor 813 can control the arc-shaped protective cover 812 to rotate 180°. At this time, the concave surface of the arc-shaped protective cover 812 is directly facing the joint area of ​​the two steel pipes, and the two sets of weld seam treatment rollers 817 can contact the joint of the steel pipes. At this time, the steel pipe is controlled to rotate for welding. The high temperature generated during welding is conducted downward and radiated to the welding center area by the heat radiation coating 818. This allows the welding center area to maintain a high temperature, which is conducive to the formation of the weld and improves the welding quality. At the same time, as the steel pipe rotates, the weld seam treatment rollers 817 can continuously roll in the welding area of ​​the steel pipe to achieve synchronous flattening treatment of the weld, which greatly improves the welding effect of the steel pipe.

[0040] Please see Figure 7 and Figure 8 A grinding disc 811 is fixedly installed at the middle position of the outer surface of the arc-shaped protective cover 812. There are mounting holes 816 on both sides of the middle part of the grinding disc 811. A weld seam treatment roller 817 is rotatably installed on the inner side of the mounting hole 816 via a rotating shaft.

[0041] Furthermore, when the moving components 6 approach each other and drive the steel pipes to connect, the side compression rod 63 can also move synchronously and press the locking block 87, causing the locking block 87 to retract into the bottom shell 84. At this time, the built-in spring 88 controls the telescopic seat 82 to spring up, and the arc-shaped protective cover 812 moves upward synchronously until the grinding disc 811 is in contact with the joint of the two steel pipes. Before actual welding, the steel pipe positioning mechanism 64 can be driven to rotate, causing the two steel pipes to rotate synchronously. During this process, the grinding disc 811 can automatically grind the joint of the two steel pipes and clean the surface impurities at the joint of the steel pipes.

[0042] This design enables the welding protection mechanism 8 to be deployed simultaneously with the connection of two steel pipes, and allows for the pretreatment of the steel pipes to prevent impurities in the welding area from affecting the welding effect.

[0043] Working principle: When welding two sets of steel pipes, first install the two sets of steel pipes on the moving component 6 respectively, then directly fit the steel pipes onto the outside of the steel pipe positioning mechanism 64. The pneumatic rod 644 can be automatically shortened, thereby pulling back the third mounting sleeve 646 connected at one end. When the third mounting sleeve 646 is pulled back, the first connecting piece 643 and the second connecting piece 647 control multiple intelligent internal support positioning components 642 to move outward until the multiple intelligent internal support positioning components 642 contact and compress with the inner wall of the steel pipe, thus completing the rapid positioning of the steel pipe. During the positioning process, if there are protruding structures or deformations on the inner wall of the steel pipe, because the multiple intelligent internal support positioning components 642 are designed in conjunction, when one or more intelligent internal support positioning components 642 come into contact with the protruding area of ​​the inner wall of the steel pipe, the other intelligent internal support positioning components 642 will inevitably not be able to fully fit against the other flat inner walls of the steel pipe. At this time, the pressure monitoring plate 6422 inside the intelligent internal support positioning component 642 that is not fully fitted against the inner wall of the steel pipe will reduce or fail to detect pressure. In this case, the two sets of fixed-point support electric actuators 6421 can be controlled to open. Two sets of fixed-point support electric actuators 6421 can contact the inner wall of the steel pipe for support. The drive motor 6424 starts to control the rotation of the grinding roller 6423, which grinds and eliminates the protruding structure inside the steel pipe until the inner contact surface of the grinding roller 6423 is flush with other areas. At this time, the other multiple intelligent internal support positioning components 642 can also stably fit against the inner wall of the steel pipe, providing a more stable support effect for the steel pipe. After positioning, the adjusting motor 7 automatically starts, driving the bidirectional threaded shaft 11 to rotate. The bidirectional threaded shaft 11 can control the two moving components 6 on it to approach each other until the two ends of the steel pipe to be welded are joined. The extension and reduction welding module 1 is automatically controlled to descend and automatically weld the joint of the two steel pipes. During this process, the rotary motor 61 can be automatically turned on, driving the steel pipe positioning mechanism 64 to rotate slowly and synchronously with the steel pipe positioned outside. At this time, the extension and reduction welding module 1 can complete the all-round circumferential welding of the steel pipe. After the welding is completed, the positioning effect of the steel pipe positioning mechanism 64 is released, and the moving components 6 can be removed to both sides to quickly remove the welded steel pipe. When the moving components 6 approach each other and drive the steel pipes to connect, the side extrusion rod 63 can also move synchronously and press the locking block 87, causing the locking block 87 to retract into the bottom shell 84. At this time, the built-in spring 88 controls the telescopic seat 82 to spring up, and the arc-shaped protective cover 812 moves up synchronously until the grinding disc 811 is in contact with the joint of the two steel pipes. Before actual welding, the steel pipe positioning mechanism 64 can be driven to rotate, causing the two steel pipes to rotate synchronously. During this process, the grinding disc 811 can automatically grind the joint of the two steel pipes and clean the surface impurities at the joint of the steel pipes. During the actual welding process, the external motor 813 can control the arc-shaped protective cover 812 to rotate 180°. At this time, the concave surface of the arc-shaped protective cover 812 is directly facing the joint area of ​​the two steel pipes. The two sets of weld seam treatment rollers 817 can contact the joint of the steel pipes. At this time, the steel pipe is controlled to rotate for welding. The high temperature generated during welding is conducted downward and radiated to the welding center area by the heat radiation coating 818. This allows the welding center area to maintain a high temperature, which is conducive to the formation of the weld and improves the welding quality. At the same time, as the steel pipe rotates, the weld seam treatment rollers 817 can continuously roll in the welding area of ​​the steel pipe to achieve synchronous smoothing of the weld.
