Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding equipment, in particular to a novel pipeline welding equipment. Background Art
[0002] Hollow pipes are essential materials for construction projects, and are commonly used in water pipes, drainage pipes, gas pipes, heating pipes, electrical conduits, and storm drains. With the advancement of science and technology, the pipes used in home renovations have evolved from ordinary cast iron pipes to cement pipes (reinforced concrete pipes, asbestos cement pipes), ductile iron pipes, galvanized steel pipes, plastic pipes, and aluminum-plastic composite pipes. However, when using pipes, it is inevitable that they will be insufficient in length.
[0003] With the rapid development of modern science and technology, most modern industrial production is done by mechanical means. Among them, the welding of hollow pipes is done by welding machines, which can save a lot of time and improve efficiency. However, no matter where the welding is done, the materials to be welded must be spliced in advance to ensure that the welding surfaces are in contact and the weld line is flush, so that the welding quality can be improved. However, the splicing process of the materials is cumbersome and requires multiple adjustments.
[0004] However, when welding hollow pipes, manual work is generally required to determine the welding position during the welding process. If the worker misjudges the position of the welding point, it is easy for the welding to be incomplete, causing the welding position to shift. At the same time, the position of the welding head needs to be adjusted at the same time, which is extremely time-consuming and requires a long preparation time.
[0005] Furthermore, when butt welding thin-walled hollow pipes, deformation and cracks are prone to occur due to the thin wall thickness of the pipes, resulting in substandard assembly precision and even product scrapping. Furthermore, existing pipe butt welding tools have poor post-butt welding stability, making it difficult to guarantee weld quality.
[0006] Therefore, a new type of pipeline welding equipment is proposed to solve the current shortcomings. Utility Model Content

[0036] Combined with attachment Figure 1-6 As shown, a new type of pipeline welding equipment includes a base 1 and a fixing part 2 and a clamping part 3 arranged on the base 1; during implementation, the structure of the base 1 can be set according to actual conditions. In this embodiment, the base 1 is a rectangular plate structure, which can be easily placed and can facilitate the equipment to cooperate with other workbenches through the base 1.
[0037] The clamping part 3 is slidably arranged on the base 1. Specifically, the base 1 is provided with a group of slideways arranged along the length direction of the base 1. The clamping part 3 is provided with a slider that cooperates with the slideways, so that the clamping part 3 can realize reciprocating movement on the base 1.
[0038] The fixing parts 2 are arranged on both sides of the clamping part 3 and are arranged linearly along the extension direction of the base 1, and any of the fixing parts 2 is arranged to slide along the extension direction of the base 1;
[0039] In a specific implementation, the fixing part 2 is arranged on both sides of the clamping part 3, wherein the fixing part 2 on one side of the clamping part 3 is fixedly connected to the base 1, and the fixing part 2 on the other side is slidably matched with the base 1. Similarly, the fixing part 2 is provided with a slider that cooperates with the slide, so that the fixing part 2 can realize reciprocating movement on the base 1.
[0040] Furthermore, by moving the movable fixing portion 2 and the clamping portion 3, the clamping portion 3 and the fixing portion 2 can be matched and separated;
[0041] The clamping portion 3 includes a support frame 31 and a spliced gear 32. Specifically, the support frame 31 is a U-shaped structure with an upward opening. A slider is provided at the bottom of the support frame 31 to enable the clamping portion 3 to reciprocate on the base 1.
[0042] The spliced gear 32 is movably arranged on the inner side of the support frame 31. Specifically, the structure of the spliced gear 32 can refer to the structure of a new spliced gear with application number 202420191093X. During implementation, the spliced gear 32 can fix the connecting tube, and the length of the connecting tube is greater than the thickness of the spliced gear 32.
[0043] The support frame 31 is located above the spliced gear 32 and is slidably provided with a limit rod 33. Specifically, the limit rod 33 can be moved along the height direction of the support frame 31. The upward movement of the support frame 31 can facilitate the installation and disassembly of the spliced gear 32.
[0044] Furthermore, limit pins 5 are provided at both ends of the limit rod 33 for limiting the position between the limit rod 33 and the support frame 31. By setting the limit pins 5, the stability of the cooperation between the transmission teeth 34 on the limit rod 33 and the spliced gear 32 can be ensured.
[0045] Transmission teeth 34 meshing with the spliced gear 32 are provided at the bottom of the support frame 31 and the lower side of the limiting rod 33 . Specifically, there are four transmission teeth 34 , which are respectively located at the four corners of the spliced gear 32 .
[0046] By providing four transmission teeth 34 meshing with the spliced gear 32 , the spliced gear 32 can be supported while ensuring the stability of the rotation of the spliced gear 32 .
[0047] At the same time, in order to prevent the spliced gear 32 from axial movement, limiting rings that cooperate with the side surfaces of the transmission teeth 34 can be provided on both sides of the spliced gear 32.
[0048] The limiting rod 33 is provided with a driving motor 35 connected to a transmission tooth 34 . The driving motor 35 drives the connected transmission tooth 34 , thereby driving the spliced gear 32 to rotate.
[0049] The fixing portion 2 includes a fixing frame 21 and a fixing half ring 22. Specifically, the fixing frame 21 is a U-shaped structure with an opening upward. A slider is provided at the bottom of the fixing frame 21 to enable the fixing portion 2 to reciprocate on the base 1.

Furthermore, limit pins 5 are provided at both ends of the positioning rod 23 to limit the relative position between the positioning rod 23 and the fixing frame 21. By setting the limit pins 5, the fixing frame 21 can be ensured to cooperate with the fixing half ring 22 on the positioning rod 23, and the fixing half ring 22 can be used to achieve fixed clamping of the hollow pipe to be welded;
[0051] In order to avoid damage to the hollow pipe to be welded caused by the fixing half ring 22 during the process of fixing the hollow pipe to be welded, a thin soft pad can be provided on the inner side of the fixing half ring 22 .
[0052] The inner side of the fixing frame 21 and the lower side of the positioning rod 23 are both provided with fixed half rings 22 that can cooperate with each other. Specifically, the fixed half rings 22 that can cooperate with each other form a complete circular ring structure.
[0053] During implementation, the circular ring structure formed by the fixed half ring 22 is coaxially arranged with the spliced gear 32. During implementation, it can ensure that the pipeline to be welded located in the fixed part 2 and the connecting pipe located in the clamping part 3 are coaxially arranged to ensure that the two ends of the connecting pipe are matched with the pipeline to be welded.
[0054] A through hole 321 is provided in the spliced gear 32, and the connection pipe can be fixedly clamped by the setting of the through hole 321; the diameter of the through hole 321 is the same as the inner diameter of the circular ring structure formed by the fixed half ring 22 to meet the welding requirements for pipelines of the same specifications.
[0055] It also includes a cylinder 4. In this embodiment, the cylinder 4 is a double-section cylinder. The cylinder 4 is arranged on both sides of the fixed part 2 fixed on the base 1, and the telescopic ends of the cylinder 4 are respectively connected to the corresponding clamping part 3 and the fixed part 2.
[0056] During implementation, when the fixing part 2 and the clamping part 3 need to be separated, the first-level cylinder of the oil cylinder 4 is extended first to push the movable fixing part 2, and when the second-level cylinder of the oil cylinder 4 is extended, the clamping part 3 is pushed. When the fixing part 2 and the clamping part 3 need to cooperate, the first-level cylinder of the oil cylinder 4 is retracted first, driving the movable fixing part 2 to move toward the clamping part 3. When the movable fixing part 2 and the clamping part 3 cooperate, the second-level cylinder of the oil cylinder 4 continues to retract, driving the movable fixing part 2 and the clamping part 3 to move toward the fixed fixing part 2, thereby achieving the cooperation between the fixing part 2 and the clamping part 3.
[0057] During the specific implementation of the present invention, before installation, the fixing portion 2 and the clamping portion 3 are separated by extending the oil cylinder 4;
[0058] Lift the positioning rod 23 to separate the fixed half ring 22 on the positioning rod 23 from the fixed half ring 22 on the fixing frame 21, and at the same time place the hollow pipe to be welded in the fixed half ring 22 on the fixing frame 21, then move the positioning rod 23 downward, and make the fixed half ring 22 on the positioning rod 23 cooperate with the fixed half ring 22 on the fixing frame 21 to fix the hollow pipe to be welded, and then fix the positioning rod 23 to the fixing frame 21 through the limit pin 5.
[0059] At the same time, the limiting rod 33 in the clamping part 3 is lifted, and the spliced gear 32 is separated, and then the connecting hollow tube is placed in the spliced gear 32, and the spliced gear 32 is spliced at the same time to fix the connecting hollow tube, and then the limiting rod 33 is moved down to make the transmission tooth 34 cooperate with the spliced gear 32, and the limiting pin 5 is used to fix the limiting rod 33 and the support frame 31.
[0060] Finally, by contracting the oil cylinder 4, the cooperation between the fixing part 2 and the clamping part 3 is achieved, and it is ensured that the hollow tubes to be welded fixed in the fixing part 2 on both sides of the clamping part 3 and the connecting hollow tubes in the clamping part 3 are docked. Then the drive motor 35 is started to realize the rotation of the splicing gear 32, thereby driving the rotation of the connecting hollow tube, so as to achieve friction welding between the connecting hollow tube and the hollow tube to be welded.
[0061] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
