Description

Technical Field

[0001] This utility model relates to the field of auxiliary welding devices, and in particular to a small auxiliary welding device for preventing pipe opening blockage. Background Technology

[0002] Welding small pipes requires selecting appropriate welding equipment and materials to ensure the pipes are securely fixed. Temperature and current must be carefully controlled during the welding process to avoid welding defects, thus guaranteeing weld quality and the safe use of the pipes.

[0003] To prevent welding defects, existing small pipe welding methods typically involve placing a rubber pad inside the pipe on both sides of the weld to seal both sides of the weld, creating an argon-filled protective space inside the pipe on both sides of the weld. Although this method is simple, it is inconvenient to place the rubber pad before welding and remove it after welding. Furthermore, the position of the rubber pad may shift during the welding process, causing the initial sealing to fail, which is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a small auxiliary welding device for preventing pipe opening blockage, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a small auxiliary welding device for preventing pipe end blockage, comprising:

[0034] 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. Example

[0035] This utility model provides, for example Figure 1-3 The small-sized auxiliary welding device for preventing pipe blockage includes a base 1, a bidirectional screw 2, a movable plate 3, a fixing mechanism 4, and an anti-blocking mechanism 5. The bidirectional screw 2 is rotatably mounted inside the base 1. The movable plate 3 and the bidirectional screw 2 form a screw drive. The fixing mechanism 4 is mounted on the movable plate 3 and is used to fix the pipe. The distance between the two movable plates 3 can be adjusted by rotating the bidirectional screw 2, thereby adjusting the fixed distance between the pipes to be welded. After being adjusted to a suitable position, the pipe to be welded can be fixed by the fixing mechanism 4, ready for welding operations. The anti-blocking mechanism 5 is mounted on the base 1 and is used to block the pipe welding position. The anti-blocking mechanism 5 can divide the pipe welding position, thereby effectively preventing foreign objects such as welding slag from entering the interior of the pipe and affecting the normal use after the subsequent welding is completed.

[0036] The fixing mechanism 4 includes a pressing plate 41, a pressing rod 42, and a slider 43. The top of the moving plate 3 has a through groove. The pressing plate 41 is located inside the through groove. One end of the pressing rod 42 is threadedly connected to the top of the inner wall of the through groove, and the other end of the pressing rod 42 is rotatably connected to the pressing plate 41. The slider 43 is fixedly connected to both sides of the pressing plate 41. Both sides of the through groove have sliding grooves that cooperate with the slider 43. By rotating the pressing rod 42, the pressing plate 41 can be moved vertically along the sliding groove, thereby clamping and fixing pipes of different specifications. Rubber pads 6 are fixedly connected to the bottom of the pressing plate 41 and the inner wall of the through groove. The rubber pads 6 have anti-slip textures and can protect the pipes from being pinched, facilitating normal use afterwards.

[0037] The anti-blocking mechanism 5 includes a moving rod 51, an insertion rod 52, a sealing head 53, and a sealing ring 54. The moving rod 51 is slidably inserted into the base 1. One end of the insertion rod 52 is fixedly connected to the moving rod 51, and the other end of the insertion rod 52 has an external thread. The sealing head 53 is threadedly inserted into the other end of the insertion rod 52. The threaded connection facilitates the replacement of the sealing head 53 for pipes of different specifications. The sealing ring 54 is symmetrically fixedly sleeved on the outside of the sealing head 53. By using a sealing head 53 and sealing ring 54 of appropriate size, after the two pipes to be welded are fixed together by the fixing mechanism 4, the sealing head 53 and sealing ring 54 are inserted into the pipe to be welded through the insertion rod 52, so that the center position of the two sealing rings 54 is exactly at the gap of the weld between the two pipes. This ensures that the pipe welding area can be completely sealed, preventing impurities such as high-temperature molten metal generated during welding from overflowing into the pipe and affecting the welding quality. It also prevents external impurities from entering the welding area, providing a reliable guarantee for high-quality welding. Example

[0038] Based on Example 1, such as Figure 4As shown, the anti-blocking mechanism 5 also includes a rotating plate 55, a snap-fit ​​rod 56, a pull rod 57, and a compression spring 58. The rotating plate 55 is rotatably connected to one end of the moving rod 51. A snap-fit ​​groove is provided at the top of the rotating plate 55. A turntable 7 is fixedly connected to one end of the bidirectional screw 2. Snap-fit ​​holes are provided at equal intervals on the outer wall of the turntable 7. One end of the snap-fit ​​rod 56 is slidably inserted into the inner cavity of the snap-fit ​​groove, and the other end of the snap-fit ​​rod 56 is slidably inserted into the inner cavity of the snap-fit ​​hole. A pull groove communicating with the snap-fit ​​groove is provided on the outer wall of the rotating plate 55. The pull rod 57 passes through the pull groove and is fixedly connected to the snap-fit ​​rod 56. A compression spring 58 is located inside the snap-fit ​​groove. One end of the compression spring 58 is fixedly connected to the snap-fit ​​rod 56, and the other end of the compression spring 58 is fixedly connected to the inner wall of the snap-fit ​​groove. The compression spring 58 is always in a compressed state, which can provide a stable elastic force to the snap-fit ​​rod 56. When the snap-fit ​​rod 56 is snapped into the snap-fit ​​hole opened on the turntable 7, it can prevent the bidirectional screw 2 from rotating during welding and causing loosening. It can also prevent the moving rod 51 from shifting, causing the sealing head 53 and the sealing ring 54 to misalign and affect the subsequent normal welding, which is convenient for use.

[0039] 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.
