Description

Technical Field

[0001] This utility model relates to the field of joint welding technology, and in particular to a joint welding mechanism for precision steel pipes used in automobiles. Background Technology

[0002] In automobile manufacturing, precision steel pipes serve as supporting components for vehicle body structures or functional parts, and their connection quality directly affects the overall structural strength and welding precision of the vehicle. To improve the connection strength and processing efficiency between steel pipes, a joint welding mechanism is typically used to align and fix the joints of the steel pipes and perform automated welding, thereby ensuring uniform weld gaps and accurate positioning. To meet the positioning requirements of steel pipes of different diameters and lengths, the joint welding mechanism is usually equipped with adjustable clamping components and a moving positioning structure to achieve multi-specification adaptation and high-precision docking.

[0003] Most existing joint welding mechanisms use mechanical slide rails and clamp-type limiting structures to limit and fix the steel pipe, achieving initial alignment of the pipe through screw drive or manual adjustment of the slide position. During welding, the mechanism relies on the welding torch to move along a set track to complete the joint welding operation. Simultaneously, some systems are equipped with manual or pneumatic drive devices to move the slider, thereby opening and closing the clamps and clamping the pipe fittings. However, this type of structure has low adjustment efficiency for adapting to steel pipes of different diameters, poor synchronization, and is prone to positioning deviations, affecting welding accuracy.

[0004] However, existing joint welding mechanisms generally suffer from the following problems: when steel pipes are placed on the operating table for welding, the steel pipes are prone to shifting or misaligning during the positioning process due to limitations in the clamping structure and the linkage of moving parts, resulting in uneven weld seams and reduced welding accuracy. Especially when changing steel pipes of different specifications, operators need to frequently adjust the clamps and limiting structures, increasing operational complexity and reducing processing efficiency. Therefore, how to achieve automatic linkage adjustment of the limiting structure and accurately limit the positions of multiple steel pipe specifications has become a key technical issue in improving the applicability and stability of joint welding mechanisms. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a precision steel pipe welding mechanism for automobiles, which aims to improve the problem of misalignment that occurs when the steel pipe is placed directly on the operating table.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precision steel pipe welding mechanism for automobiles, comprising a base, a guide rail fixedly connected to the top of the base, a bracket fixedly connected to the top of the base, an electric push rod fixedly connected to the outer wall of the bracket, a welding head fixedly connected to the output end of the electric push rod, an electric push rod two fixedly connected to the top of the base, a limit roller fixedly connected to the output end of the electric push rod two, and a limit component provided on the top of the base;

[0007] The limiting component includes a second base, which is slidably connected inside the guide rail. A symmetrically arranged slider is slidably connected to the top of the second base. A limiting block is fixedly connected to the top of the slider. A limiting roller is rotatably connected inside the limiting block. A synchronization component is provided inside the second base, and a driving component is provided on the outer wall of the slider.

[0008] As a further description of the above technical solution:

[0009] The synchronization component includes a gear, the bottom of which is rotatably connected to the inside of the base. A rack is fixedly connected to one side of the slider, and the rack meshes with the gear.

[0010] As a further description of the above technical solution:

[0011] The drive assembly includes an electric push rod three, both ends of which are fixedly connected between the sliders.

[0012] As a further description of the above technical solution:

[0013] The base 2 is fixedly connected to the bottom of the bracket 2, and adjustment blocks are fixedly connected to both ends of the bracket 2.

[0014] As a further description of the above technical solution:

[0015] The adjusting block is slidably connected inside the guide rail, and a wedge-shaped locking block is rotatably connected inside the adjusting block.

[0016] As a further description of the above technical solution:

[0017] A knob is fixedly connected to one end of the second wedge-shaped block, and a knob is threadedly connected to the outer wall of the second wedge-shaped block.

[0018] As a further description of the above technical solution:

[0019] The adjustment block is fixedly connected to a second limiting block, which is slidably connected inside the knob.

[0020] As a further description of the above technical solution:

[0021] The adjusting block has a wedge-shaped locking block slidably connected inside, and an anti-sliding block is fixedly connected to the top of the wedge-shaped locking block. The top of the anti-sliding block is in contact with the inner wall of the guide rail.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the output end of the electric push rod retracts first, causing the slider to slide on the outer wall of the base. The slider meshes with the gear on the outer wall through the rack, thereby driving the sliders on both sides to move synchronously. Then, the limiting block pair fits into the outer wall of the steel pipe, achieving the effect of adapting to steel pipes of different sizes and making them easier to move. This solves the problem of misalignment when the steel pipe is placed directly on the operating table in the seam welding mechanism, and improves the practicality of the seam welding mechanism.

[0024] 2. In this utility model, the second wedge-shaped locking block drives the second limiting block to extend into the interior of the adjusting block by the limiting block. Then, the outer wall of the knob contacts and adheres to the bottom of the first wedge-shaped locking block, causing the first wedge-shaped locking block to drive the anti-sliding block to extend out of the adjusting block. The anti-sliding block then adheres to the inner wall of the guide rail for fixation, achieving the effect of facilitating the adjustment of the spacing between the limiting blocks. This solves the problem of inconvenience in adjusting the joint welding mechanism when welding steel pipes of different lengths, and improves the convenience of the joint welding mechanism.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a precision steel pipe welding mechanism for automobiles, comprising a base 1, which supports the overall structure and provides an installation reference. A guide rail 7 is fixedly connected to the top of the base 1, providing a guide track for the sliding movement of the limiting component. A bracket 2 is fixedly connected to the top of the base 1, serving as an installation support component to support the installation requirements of an electric push rod 3. The electric push rod 3 is fixedly connected to the outer wall of the bracket 2, and is telescopically driven to adjust the position of the welding head 4. The electric push rod 3 outputs... A welding head 4 is fixedly connected to the end of the steel pipe. The welding head 4 is used to perform welding operations on the joint of the steel pipe to form a weld. An electric push rod 5 is fixedly connected to the top of the base 1. The electric push rod 5 can adjust the position of the limiting roller 6 to achieve initial clamping and limiting of the steel pipe. The output end of the electric push rod 5 is fixedly connected to the limiting roller 6. The limiting roller 6 is used to cooperate with the limiting roller 11 to clamp the steel pipe and prevent the steel pipe from shifting during the welding process. A limiting component is set on the top of the base 1. The limiting component is used to realize the adaptive limiting clamping function of the steel pipe under different diameter sizes.

[0034] The limiting component includes a second base 8, which serves as the mounting base for the limiting component and can slide along the guide rail 7 to adjust its position. The second base 8 is slidably connected inside the guide rail 7, enabling linear movement of the entire limiting component on the guide rail 7 through the sliding connection. A pair of symmetrically arranged sliders 9 are slidably connected to the top of the second base 8 to support the first limiting block 10 and move synchronously to accommodate steel pipes of different diameters. The first limiting block 10 is fixedly connected to the top of the slider 9, and the first limiting block 10 is used to fit against the outer wall of the steel pipe for reliable limiting and fixing. A second limiting roller 11 is rotatably connected inside the first limiting block 10. The second limiting roller 11 can adaptively fit with the rotation of the steel pipe during the limiting process, thereby preventing scratches on the steel pipe surface. A synchronization component is provided inside the second base 8 to coordinate the synchronous movement of the sliders 9 and maintain the symmetrical clamping effect of the limiting structure. A drive component is provided on the outer wall of the slider 9 to provide driving force to push the slider. The relative movement of blocks 9 enables clamping or releasing operations. The synchronization component includes gear 13, which transmits the driving displacement between the two sliders 9 to achieve a linkage and synchronization effect. The bottom of gear 13 is rotatably connected inside the base 8. The rotational installation of gear 13 ensures that it can mesh with rack 14 for transmission. A rack 14 is fixedly connected to one side of slider 9. During the movement of slider 9, rack 14 drives gear 13 to rotate, thereby driving the opposite slider 9 to move in linkage. Rack 14 meshes with gear 13. The transmission relationship of synchronous movement of the two sliders 9 is achieved through the meshing structure of gear 13 and rack 14. The driving component includes electric push rod 12, which drives slider 9 to move along the direction of guide rail 7 to realize the contraction or expansion of limit block 10. Both ends of electric push rod 12 are fixedly connected between sliders 9. The extension and retraction of electric push rod 12 realizes the equidistant driving control of the two sliders 9, improving the adaptive performance of the limit structure.

[0035] Reference Figure 4 and Figure 5The base 28 has a bracket 2 15 fixedly connected to its bottom. The bracket 2 15 supports and connects the base 28 to the adjustment structure, ensuring the structural stability of the limiting component on the guide rail 7. Adjusting blocks 16 are fixedly connected to both ends of the bracket 2 15. The adjusting blocks 16 allow for precise movement of the bracket 2 15 along the guide rail 7, used for position adjustment and positioning. The adjusting blocks 16 are slidably connected inside the guide rail 7, enabling adjustable fit between the adjusting blocks 16 and the guide rail 7, enhancing the adaptability of the device. A wedge-shaped locking block 20 is rotatably connected inside the adjusting block 16. When rotated, the wedge-shaped locking block 20 drives the limiting block 2 17 to insert or retract from the adjusting block 16. A knob 21 is fixedly connected to one end of the wedge-shaped locking block 20, serving as a manual drive component for manually adjusting the angle of the wedge-shaped locking block 20. The outer wall of the wedge-shaped locking block 20 is threaded with the knob 21. Through this threaded connection, the knob 21... 1. The wedge-shaped locking block 20 can be driven to achieve axial displacement, thereby completing the limiting or releasing operation. The adjusting block 16 is fixedly connected to the limiting block 27. The limiting block 27 is used to physically limit the slider 9 and other components during the adjustment process to prevent them from moving beyond the range. The limiting block 27 is slidably connected inside the knob 21. This slidable connection ensures that the limiting block 27 can achieve axial movement and reset under the drive of the knob 21. The adjusting block 16 is slidably connected to the wedge-shaped locking block 18. The wedge-shaped locking block 18 can move inside the guide structure to control the movement state of the anti-sliding block 19. The top of the wedge-shaped locking block 18 is fixedly connected to the anti-sliding block 19. The anti-sliding block 19 can extend or retract under the drive of the wedge-shaped locking block 18 to achieve effective contact and fixation with the guide rail 7. The top of the anti-sliding block 19 is in contact with the inner wall of the guide rail 7. This contact structure can enhance the stability of the overall limiting component on the guide rail 7 and prevent the device from shaking or displacing during use.

[0036] Working principle: When using this automotive precision steel pipe welding mechanism, firstly, when adjusting the position of the two limit blocks 10 on the guide rail 7, the bottom of the limit block 10 slides in the guide rail 7 through the adjusting blocks 16 on both sides of the bracket 2 15. After the adjustment is in place, the knob 21 drives the wedge-shaped card block 20 to rotate. The wedge-shaped card block 20 drives the limit block 17 to extend into the adjusting block 16 with the limit of the limit block 17. Then, the outer wall of the knob 21 contacts and adheres to the bottom of the wedge-shaped card block 18, so that the wedge-shaped card block 18 drives the anti-sliding block 19 to extend out of the adjusting block 16. Then, the anti-sliding block 19 adheres to the inner wall of the guide rail 7 for fixation, thus achieving the effect of facilitating the adjustment of the distance between the limit blocks.

[0037] When installing the steel pipe, the steel pipe is placed between the limiting blocks 10. Then, the output end of the electric push rod 12 retracts, causing the slider 9 to slide on the outer wall of the base 2 8. The slider 9 meshes with the gear 13 on the outer wall through the rack 14, thereby causing the sliders 9 on both sides to move synchronously. Then, the limiting blocks 10 fit against the outer wall of the steel pipe. At the same time, the output end of the electric push rod 2 5 extends, causing the limiting roller 6 to fit against the outer wall of the steel pipe for further limiting. Then, the output end of the electric push rod 3 extends, causing the welding head 4 to descend to weld the steel pipe. This achieves the effect of adapting to steel pipes of different sizes and making them easier to move.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
