Furthermore, the production cost of gas pipelines increases because different models of industrial gas pipeline welding equipment are required. Summary of the Invention

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an automatic welding device for convenient installation of industrial gas pipelines, comprising an installation mechanism, a clamping mechanism, and a welding mechanism. The installation mechanism includes a bearing plate, an adjustment groove is provided in the middle of the upper surface of the bearing plate, guide grooves are provided on both sides of the upper surface of the bearing plate, a first installation cavity is provided in the middle of the outer wall of the front end of the bearing plate, a first servo motor is provided at the front end of the bottom surface inside the first installation cavity, and a second bidirectional threaded rod is fixedly connected to the output shaft of the first servo motor. The clamping mechanism includes two clamping frames, and an adjustment block is fixedly connected to the middle of the lower surface of each clamping frame. The outer wall of the second bidirectional threaded rod is threadedly connected to the adjustment block. Each of the inner walls on one side of the clamping frame has a first limiting groove, and each of the inner walls on the other side of the clamping frame has a second limiting groove. The bottom surface inside each of the second limiting grooves is rotatably connected to a first bidirectional threaded rod. The upper end of each of the first bidirectional threaded rods passes through the second limiting groove to the outside of the clamping frame and is fixedly connected to a first rotating handle. The upper and lower ends of the outer wall of the first bidirectional threaded rod are threadedly connected to clamping blocks. The welding mechanism includes a mounting frame, the lower surface of which is fixedly connected to a bearing plate. A control panel is fixedly connected to the upper part of one outer wall of the mounting frame. A second mounting cavity is opened in the middle of one outer wall of the mounting frame. A mounting block is fixedly connected to the bottom surface inside the second mounting cavity. A second servo motor is provided on the upper surface of the mounting block. A worm gear is fixedly connected to the output shaft of the second servo motor. Assisting bearings are fixedly connected to the other side of the inner walls of the front and rear ends of the second mounting cavity. An active rotating rod is fixedly connected to the inner wall of each assisting bearing. A worm wheel is fixedly connected to the middle of the outer wall of the active rotating rod. An adjusting bearing is fixedly connected to the inner wall of the mounting frame. A gear ring is fixedly connected to the inner wall of the adjusting bearing. A welding ring is fixedly connected to the inner wall of the gear ring by multiple rods. A connecting cylinder is fixedly connected inside the welding ring. A No. 3 adjusting threaded rod is rotatably connected to the center of the bottom surface inside the connecting cylinder. The upper end of the No. 3 adjusting threaded rod passes through the connecting cylinder to the outside of the connecting cylinder and is fixedly connected to a No. 2 rotating handle. The outer wall of the No. 3 adjusting threaded rod is threaded with a limit plate. The No. 2 rotating handle has a No. 2 mounting groove inside. An annular plate is slidably connected inside the No. 2 mounting groove. A pin is fixedly connected to the inner wall of the annular plate. The upper end of the pin passes through the No. 2 mounting groove to the outside of the No. 2 rotating handle and is fixedly connected to a positioning block. A pull ring is fixedly connected to the middle of the upper surface of the positioning block. The above technical solution allows for the clamping of gas pipelines of different diameters by setting an adjustable clamping block clamping frame. The adjustable height laser welding head enables welding operations on different gas pipelines, eliminating the need for different models of industrial gas pipeline welding equipment. This reduces the production cost of gas pipelines and eliminates the need for frequent equipment replacement or adjustment, thus reducing the complexity of operation and labor costs for workers.
[0006] Preferably, a second sealing plate is fixedly connected to the outer wall of one side of the second mounting cavity by multiple bolts, and the other side of the worm is rotatably connected to the inner wall of the other side of the second mounting cavity, and the worm wheel is meshed with the worm. Through the above technical solution, the No. 2 sealing plate can prevent external objects from contacting the electrical equipment installed inside the No. 2 installation cavity, and the No. 2 servo motor drives the worm gear to rotate, thereby causing the active rotating rod equipped with the worm wheel to rotate, which in turn causes the active gear to rotate. Furthermore, the cooperation between the worm wheel and the worm gear prevents the active rotating rod from reversing.
[0007] Preferably, the rear end of the active rotating rod passes through the second mounting cavity to the outside of the mounting frame and is fixedly connected to an active gear, and the gear ring meshes with the active gear; The above technical solution uses a drive gear to rotate a gear ring, allowing the laser welding head to circle the gas pipeline and complete the welding operation around the gas pipeline.
[0008] Preferably, the limiting plate slides inside the connecting cylinder, and the front and rear ends of the lower surface of the limiting plate are fixedly connected with arc-shaped rods. The lower ends of the arc-shaped rods penetrate the connecting cylinder to the outside of the connecting cylinder and are fixedly connected with the connecting plate. The lower surface of the connecting plate is fixedly connected with a laser welding head by multiple bolts. The above technical solution involves rotating the No. 3 adjusting threaded rod using the No. 2 rotating handle, which causes the limiting disc with the arc-shaped rod to slide inside the connecting cylinder. This adjusts the distance between the laser welding head and the outer wall of the gas pipeline, ensuring that the laser beam can be focused on the weld, thereby achieving high-quality welding.
[0009] Preferably, the lower end of the pin passes through the No. 2 mounting groove to the outside of the No. 2 rotating handle and fits tightly with the annular groove opened on the upper surface of the connecting cylinder. A return spring is fixedly connected to the middle of the upper surface of the annular plate. The upper end of the return spring is fixedly connected to the top surface inside the No. 2 mounting groove. A wiring port is provided at the lower end of the outer wall on the other side of the mounting frame. The above technical solution uses a pin and a ring plate with a return spring to restrict the rotation of the second rotating handle, thereby fixing the position of the laser welding head.
[0010] Preferably, guide rods are fixedly connected to the bottom and top surfaces inside the first limiting groove, and the clamping blocks are slidably connected to the outer wall of the guide rod body. The clamping blocks slide inside the first limiting groove and the second limiting groove respectively. The above technical solution improves the stability of the clamping block's movement by limiting the direction of movement of the clamping block through the guide rod.
[0011] Preferably, a first mounting groove is formed at the edge of the lower surface of the first rotating handle. A second adjusting threaded rod is threadedly connected to the middle of the top surface inside the first mounting groove. A knob is fixedly connected to the upper end of the second adjusting threaded rod. A fixing block is rotatably connected to the lower end of the second adjusting threaded rod. The fixing blocks slide inside the first mounting groove and are in close contact with the upper surface of the clamping frame. The above technical solution allows the second adjusting threaded rod, which has a fixed block, to rotate by turning a knob, thereby adjusting the height of the fixed block and restricting the rotation of the first rotating handle, thus preventing the first bidirectional threaded rod from rotating.
[0012] Preferably, the outer wall of the front end of the first mounting cavity is fixedly connected to the first sealing plate by multiple bolts, and the rear end of the second bidirectional threaded rod passes through the first mounting cavity and the bearing plate in sequence to the interior of the adjustment groove and is rotatably connected to the inner wall of the rear end of the adjustment groove. The above technical solution prevents external objects from contacting the electrical equipment inside the No. 1 installation cavity by using the No. 1 sealing plate, and rotates the No. 2 bidirectional threaded rod by using the No. 1 servo motor, thereby causing the adjusting block to slide inside the adjusting groove, thus adjusting the distance between the two clamping frames, which makes it convenient for staff to check the relative position of the two gas pipelines before welding.
[0013] Preferably, the adjusting blocks slide inside the adjusting grooves, and guide blocks are fixedly connected to both sides of the lower surface of the clamping frame, and the guide blocks slide inside the corresponding guide grooves. The above technical solution, through the setting of guide blocks, can improve the stability of the movement of the two clamping frames.

A pull ring 328 is fixedly connected to the middle of the upper surface of the positioning block 327. By using the servo motor 309 with worm gear 310 and the active rotating rod 313 with worm wheel 314, the active gear 315 can drive the gear ring 304 with laser welding head 321 to rotate, thereby completing the welding operation of one revolution at the gas pipeline interface and improving the welding efficiency of the gas pipeline.
[0020] The outer wall of one side of the second mounting cavity 307 is fixedly connected to the second sealing plate 316 by multiple bolts. The other side of the worm 310 is rotatably connected to the inner wall of the other side of the second mounting cavity 307. The worm wheel 314 is meshed with the worm 310. The second sealing plate 316 can prevent external objects from contacting the electrical equipment installed inside the second mounting cavity 307. The second servo motor 309 drives the worm gear 310 to rotate, thereby causing the active rotating rod 313 equipped with the worm wheel 314 to rotate, which in turn causes the active gear 315 to rotate. The cooperation between the worm wheel 314 and the worm gear 310 prevents the active rotating rod 313 from reversing.

The gear ring 304 meshes with the active gear 315. The drive gear 315 drives the gear ring 304 to rotate, so that the laser welding head 321 can circle the gas pipeline, thereby completing the welding operation of the gas pipeline around one circumference.
[0022] The limiting plate 318 slides inside the connecting cylinder 317. The front and rear ends of the lower surface of the limiting plate 318 are fixedly connected to the arc rod 319.

The lower surface of the connecting plate 320 is fixedly connected to the laser welding head 321 by multiple bolts. The No. 3 adjusting threaded rod 322 is rotated by the No. 2 rotating handle 323, so that the limiting plate 318 with the arc-shaped rod 319 slides inside the connecting cylinder 317, thereby adjusting the distance between the laser welding head 321 and the outer wall of the gas pipeline, ensuring that the laser beam can be focused on the weld, thereby achieving high-quality welding.

[0024] Guide rods 205 are fixedly connected to the bottom and top surfaces inside the first limiting groove 204, and clamping blocks 213 are slidably connected to the outer wall of the guide rod 205. The clamping blocks 213 slide inside the first limiting groove 204 and the second limiting groove 206 respectively.

The second adjusting threaded rod 210, which is equipped with a fixing block 212, is rotated by knob 211, thereby adjusting the height of the fixing block 212 and restricting the rotation of the first rotating handle 208, so that the first bidirectional threaded rod 207 cannot rotate.
[0026] The outer wall at the front end of the first mounting cavity 104 is fixedly connected to the first sealing plate 105 by multiple bolts. The rear end of the second bidirectional threaded rod 107 passes through the first mounting cavity 104 and the bearing plate 101 in sequence to the interior of the adjustment groove 103 and is rotatably connected to the inner wall at the rear end of the adjustment groove 103. The first sealing plate 105 prevents external objects from contacting the electrical equipment installed inside the first mounting cavity 104. The first servo motor 106 causes the second bidirectional threaded rod 107 to rotate, thereby causing the adjusting block 203 to slide inside the adjusting groove 103, thereby adjusting the distance between the two clamping frames 201, thus facilitating the staff to check the relative position of the two gas pipelines before welding.
[0027] The adjusting blocks 203 slide inside the adjusting groove 103. Guide blocks 202 are fixedly connected to both sides of the lower surface of the clamping frame 201, and the guide blocks 202 slide inside the corresponding guide groove 102. By setting the guide block 202, the stability of the movement of the two clamping frames 201 can be improved.
[0028] Working Principle: When using this automatic welding equipment for convenient industrial gas pipeline installation, firstly, the first rotating handle 208 drives the first bidirectional threaded rod 207 to rotate, thereby adjusting the distance between the two clamping blocks 213 inside the clamping frame 201. The two clamping blocks 213 clamp the gas pipeline respectively. Then, the second adjusting threaded rod 210, which is equipped with a fixing block 212, is rotated by the knob 211, thereby adjusting the height of the fixing block 212 and restricting the rotation of the first rotating handle 208, thus preventing the first bidirectional threaded rod 207 from rotating. Secondly, the first servo motor 106 is started by the control panel 306 to rotate the second bidirectional threaded rod 107, thereby causing the adjusting block 203 to slide inside the adjusting groove 103, thereby adjusting the distance between the two clamping frames 201, thus allowing the gas pipeline to be clamped. The laser welding head 321 is brought closer together and a weld is formed inside the welding ring 305. Next, the third adjusting threaded rod 322 is rotated by the second rotating handle 323, so that the limiting plate 318 with the arc rod 319 slides inside the connecting cylinder 317, thereby adjusting the distance between the laser welding head 321 and the outer wall of the gas pipeline to ensure that the laser beam can be focused on the weld. Then, the laser welding head 321 is adjusted by the control panel 306. Finally, the second servo motor 309 is started by the control panel 306 and drives the worm gear 310 to rotate, so that the active rotating rod 313 with the worm wheel 314 rotates, which in turn makes the active gear 315 rotate. Subsequently, the active gear 315 drives the gear ring 304 to rotate, so that the laser welding head 321 can circle the gas pipeline, thereby completing the welding operation of one revolution of the gas pipeline.
