Description

Technical Field

[0001] This utility model relates to the field of large-diameter thin-walled tube processing, and more specifically, to an automatic tracking system for welding large-diameter thin-walled tubes. Background Technology

[0002] An automatic tracking system for welding large-diameter thin-walled pipes is an automated device designed to achieve high-precision tracking of thin-walled large-diameter pipes during the welding process and ensure welding quality.

[0003] A search revealed an existing patent (publication number: CN212350979U) that discloses a welding protection device for thin-walled tubes, comprising: a fastening sleeve, the first end of which inserts into the interior of the thin-walled tube, and the second end which clamps the second end of the thin-walled tube, with its outer wall fitting into the inner wall of the thin-walled tube; a first groove is provided on the inner wall along its axial direction, and the second end of the first groove is connected to a gas pipe; a second groove is provided on the outer wall of the fastening sleeve along its circumference; several through holes are evenly distributed at the bottom of the second groove, connecting the first groove and the second groove; and a top cover, detachably connected to the first end of the fastening sleeve, with the outer diameter of the top cover being larger than the inner diameter of the fastening sleeve, sealing the first groove. This invention solves the problems of limited welding space and low welding efficiency for thin-walled tubes. By tightening the thin-walled tube with the fastening sleeve and fastening pin, the protective gas is directly and evenly distributed into the second groove through the first groove, preventing welding deformation of the thin-walled tube, compensating for the defect of limited welding space, and improving welding efficiency.

This results in certain limitations in their use. Furthermore, the aforementioned cited patent documents do not propose any solutions to address these issues.

[0022] As attached Figures 1 to 4 An automatic tracking system for welding large-diameter thin-walled tubes is shown, comprising a frame 1. A tracking component 4 is connected to one side of the frame 1 via a welding component 3. The tracking component 4 includes a fixed frame 41. A connecting seat 42 is slidably disposed inside the fixed frame 41. A connecting groove 43 is opened inside the connecting seat 42, and a rotary motor 44 is fixedly disposed inside the connecting groove 43.

A tracking sensor 413 is fixedly disposed at the front end of the connecting seat 42, and a controller 5 is fixedly disposed on one side of the frame 1.

[0023] Among them, by setting a tracking sensor 413, the monitor 48 can be driven by the controller 5 to capture the welding video of the weld and the tungsten rod, so as to correct the welding position in real time and achieve automatic tracking operation of the pipe body 25 welding, which enhances the practicality of the device and makes it applicable to a wider range.

[0024] Example 2

[0025] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] In a preferred embodiment, a telescopic rod 410 is fixedly provided at the rear end of the connecting seat 42, and a connecting spring 411 is connected around the outside of the telescopic rod 410. One side of the connecting spring 411 is fixedly connected to the mounting seat 412. Furthermore, by providing the telescopic rod 410 and the connecting spring 411, its stability during movement is improved, making the device more widely applicable.

[0027] In a preferred embodiment, a welding assembly 3 is provided on the upper end of the mounting base 412. The welding assembly 3 includes a drive motor 31. A drive gear 32 is driven and connected to one side of the drive motor 31. A driven gear 33 is meshed and connected to one side of the drive gear 32. A connecting box 35 is connected to one side of the driven gear 33 through a fixing rod 34. Furthermore, the drive motor 31 is provided during passage. The drive motor 31 drives the drive gear 32 and the driven gear 33 meshed on one side to rotate. This facilitates the rotation of the welding head 38 to perform welding operations on the pipe body 25 while rotating the connecting box 35, thereby enhancing the practicality of the device.

[0028] In a preferred embodiment, electric push rods 36 are symmetrically and fixedly installed at both ends inside the connecting box 35. The electric push rods 36 pass through one side of the connecting box 35 and are connected to a fixing seat 37. A welding head 38 is fixedly installed at the front end of the fixing seat 37, and the upper end of the mounting seat 412 is fixedly connected to the connecting box 35. The bottom of the fixing seat 37 is fixedly connected to the connecting seat 42 through a connecting rod 49. Furthermore, by providing the electric push rods 36, the electric push rods 36 drive the welding head 38 to extend and retract, thereby facilitating adjustment according to actual needs and making the device more convenient to use.

[0029] In a preferred embodiment, a connecting component 2 is provided on one side of the frame 1. The connecting component 2 includes a connecting frame 21. A hydraulic cylinder 22 is fixedly provided on the upper end of the connecting frame 21. A hydraulic rod 23 is sleeved on one side of the hydraulic cylinder 22, and a limiting plate 24 is fixedly provided at the bottom of the hydraulic rod 23. Furthermore, by providing the hydraulic cylinder 22, the hydraulic cylinder 22 drives the hydraulic rod 23 to move, thereby driving the limiting plate 24 to limit the tube body 25, which facilitates the calibration operation between the tube bodies 25.

[0030] In a preferred embodiment, a tube body 25 is provided on the outside of the limiting plate 24, and a limiting frame 26 is attached to the inner wall of the tube body 25. The limiting frame 26 has a groove 27 inside, which is engaged with the limiting plate 24. Furthermore, by providing the limiting plate 24 and engaging the limiting plate 24 with the groove 27, the stability of the tube body 25 connection is improved, which facilitates subsequent welding operations and makes the device more convenient to use.

[0031] The working process of this utility model is as follows:

[0032] In operation, the hydraulic cylinder 22 first moves the hydraulic rod 23 and the bottom limiting plate 24 up and down, causing the limiting frame 26 to fit against the inner wall of the tube 25. This engages the limiting plate 24 with the groove 27, improving the stability of the tube 25 connection and facilitating subsequent welding. Next, the drive motor 31 rotates the drive gear 32 and the driven gear 33 meshing on one side, which in turn moves the connecting box 35 via the bottom fixing rod 34. Simultaneously, the electric push rod 36 inside the connecting box 35 extends and retracts the fixing seat 37 and the welding head 38 on one side. This allows the welding head 38 to rotate simultaneously with the connecting box 35 for welding operations on the tube 25, making the device more convenient to use. A connecting seat 42 is connected to the bottom of the connecting box 35 via a mounting seat 412. The upper end of the connecting seat 42 is connected to the fixed seat 37 via a connecting rod 49. This allows the fixed seat 37 to move while simultaneously moving the connecting seat 42 within the mounting seat 412. A rotary motor 44 is installed inside the connecting seat 42. One side of the rotary motor 44 is connected to a mounting rod 46 via a rotating shaft 45. The mounting rod 46 rotates within the movable groove 47, thereby causing the monitor 48 to rotate. A tracking sensor 413 is installed on one side, allowing the monitor 48 to capture welding video of the weld seam and tungsten rod, facilitating real-time correction of the welding position. This achieves automatic tracking of the pipe body 25 welding operation, broadening the application range of the device and improving its practicality to a certain extent.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
