[0002] Automotive pipe welding refers to the process of connecting or sealing various tubular parts (such as oil pipes, air pipes, exhaust pipes, etc.) on automobiles using specific welding techniques. When welding pipes, external or internal support is required.

[0003] For example, Chinese patent CN214816249U discloses a composite pipe welding internal support device, including a base, which is a flat plate. Semi-circular support plates are symmetrically arranged on both sides of the base. A top plate is arranged above the base. The top plate is connected to the base through a cylinder. A positioning column is arranged in the center of the top of the top plate.

[0004] In the aforementioned patent, although the problem of softened pipe indentation and deformation affecting welding quality was solved by starting the cylinder and roller, the support plate is a fixed semi-circular structure and the top plate is a fixed arc cross-section, which can only match composite pipes with a specific inner diameter. If facing pipes with larger diameters, the contact area between the support plate and the inner wall is insufficient, the support force will drop significantly, and the support effect will be reduced. Utility Model Content

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: Refer to Figures 1-4 As shown: An adjustable internal support positioning device for welding automotive pipe fittings includes a telescopic rod 3. A support mechanism is provided on one side of the telescopic rod 3. The support mechanism includes a support block 10, a guide frame 14, and a connecting plate 19. An internal rod 18 is inserted into the inner wall of the support block 10 and is slidably connected to the guide frame 14. A reinforcing block 21 is fixedly connected to one end of the internal rod 18. An auxiliary strip 17 is hinged to one side of the reinforcing block 21. One end of the auxiliary strip 17 is hinged to the connecting plate 19. The connecting plate 19 is rotatably connected to the guide frame 14, and the inner ring surface of the connecting plate 19... A connecting shaft 20 is fixedly connected. One end of the connecting shaft 20 passes through the guide frame 14 and is fixedly connected to a bevel gear 15. The bevel gear 15 is rotatably connected to the guide frame 14. A bevel gear 16 meshes with one side of the bevel gear 15. The shaft of the bevel gear 16 is fixedly connected to the output shaft of the drive motor 13. One side of the drive motor 13 is fixedly connected to the guide frame 14. A U-shaped frame 12 is fixedly connected to one side of the guide frame 14. A connecting piece 11 is fixedly connected to one side of the U-shaped frame 12. A reinforcing rod 9 is connected to the connecting piece 11 by bolts.

[0020] When the drive motor 13 is powered on, its output shaft drives the bevel gear 16 to rotate. The bevel gear 16 meshes with the bevel gear 15, causing the bevel gear 15 and the connecting shaft 20 fixed thereto to rotate synchronously. The connecting shaft 20 drives the connecting disc 19 to rotate on the guide frame 14. When the connecting disc 19 rotates, it pulls or pushes the auxiliary strip 17 through the hinge point. The auxiliary strip 17, through the hinge point with the reinforcing block 21, drives the reinforcing block 21 and the built-in rod 18 fixed thereto to slide along the guide frame 14. When the built-in rod 18 slides, it causes the support block 10 inserted into its inner wall to extend and retract, thereby achieving the internal support and positioning of the automotive pipe fitting; at the same time, the connecting... The connector 11 is connected to the reinforcing rod 9 by bolts. The U-shaped frame 12 fixes the guide frame 14 and the connector 11 to ensure the overall stability of the support mechanism. The support block 10 is telescopically adjustable to adapt to automotive pipes with different inner diameters, making it widely applicable. The built-in rod 18 slides with the guide frame 14, and the support block 10 is plugged into the built-in rod 18. With the linkage of the reinforcing block 21 and the auxiliary strip 17, it is ensured that the support block 10 is not easily offset when positioned. The U-shaped frame 12 and the connector 11 are connected to the reinforcing rod 9 by bolts. The bevel gear 15 is fixedly connected to the connecting shaft 20. All components are tightly connected and can withstand the external force during welding, preventing the device from loosening.

[0021] Example 2: Figures 1-3 As shown, a walking mechanism is provided on one side of the reinforcing rod 9. The walking mechanism includes a dual-axis motor 5, an adjusting component 7, and a support frame 8. Both ends of the dual-axis motor 5 are fixedly connected to the support frame 8. The edges of the support frame 8 are respectively hinged with a passive walking component 4 and an active walking component 2. A drive motor 1 is installed on one side of the active walking component 2. Both the active walking component 2 and the passive walking component 4 are hinged to the adjusting component 7 on one side. The adjusting component 7 is connected to a lead screw 6 by a thread. One end of the lead screw 6 is fixedly connected to the output shaft of the dual-axis motor 5. The other end of the lead screw 6 is rotatably connected to a fixing block 22. One side of one fixing block 22 is fixedly connected to the reinforcing rod 9, and the other side of the fixing block 22 is fixedly connected to a telescopic rod 3. The inner rod and the outer rod of the telescopic rod 3 are connected by a thread.

[0022] When the drive motor 1 is powered on, it drives the wheels of the active walking component 2 to rotate. The passive walking component 4 moves synchronously with the active walking component 2 under the hinge action of the support frame 8, realizing the overall movement of the device. The drive motor 1 drives the active walking component 2, which works in conjunction with the passive walking component 4 to achieve autonomous movement of the device, making it convenient to adjust the position of the device during the welding process. Since the adjusting component 7 is threadedly connected to the lead screw 6, when the lead screw 6 rotates, it drives the adjusting component 7 to move along the axial direction of the lead screw 6. When the adjusting component 7 moves, it drives the active walking component 2 and the passive walking component 4 to move through the hinge point, thereby adjusting the opening angle of the active walking component 2 and the passive walking component 4, which is convenient for adapting to pipes of different diameters. The inner rod and outer rod of the telescopic rod 3 are threadedly connected, which can flexibly adjust the overall length of the device.

[0023] The usage and working principle of this device are as follows: First, the drive motor 1 installed on one side of the active walking component 2 drives the walking wheels on the active walking component 2 to rotate, enabling automatic walking. When using the entire device, the telescopic rod 3 is used to place the device inside the automotive pipe fitting. Then, an external controller drives the dual-axis motor 5, which in turn drives the lead screw 6 to rotate. The adjusting component 7 moves along the lead screw 6, changing the angle between the active walking component 2, the passive walking component 4, and the support frame 8. This causes the walking wheels on the active walking component 2 and the passive walking component 4 to fit against the inner wall of the pipe fitting, allowing the entire device to move stably inside the pipe fitting. When the support block 10... When moving to the welding area, the drive motor 1 on one side of the active walking component 2 stops running. The gear at the end of the drive motor 1 meshes with the gear on one side of the walking wheel, and the walking wheel does not rotate. The telescopic rod 3 can be clamped and limited by the external clamping structure, and the entire device no longer moves. The drive motor 13 drives the bevel gear 16 to rotate, and the bevel gear 16 drives the bevel gear 15 to rotate. The connecting plate 19 and the bevel gear 15 rotate synchronously. After the auxiliary bar 17 is stressed, it drives the reinforcing block 21 and the built-in rod 18 to slide along the guide frame 14, thereby making the support block 10 fit against the inner wall of the pipe. The four support blocks 10 support the inside of the pipe.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
