Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and specifically refers to a new type of pipeline welding equipment. Background Art

[0002] Hollow pipes are essential materials for construction projects. Commonly used ones include water supply pipes, drainage pipes, gas pipes, heating pipes, electrical conduits, rainwater pipes, etc. With the development of science and technology, the pipes used in home decoration have also experienced a development process from ordinary cast iron pipes → 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 the length is insufficient;

[0003] With the rapid development of modern technology, most modern industrial productions are made by mechanical means. Among them, the welding of hollow pipes is carried out by a welding machine, which can save a lot of time and improve efficiency. However, no matter where it is, welding requires splicing the materials to be welded in advance to make the welding surfaces contact and ensure that the welding wires are flush, so as to improve the welding quality. However, the splicing process of the materials is cumbersome and requires multiple adjustments;

[0004] However, when welding hollow pipes, generally, the welding position needs to be determined manually during the welding process. If the staff misjudges the position of the welding point, it is easy to cause incomplete welding and the welding position to shift. At the same time, the position of the welding head also needs to be adjusted, which is extremely time-consuming and the preparation work is long.

[0005] Moreover, when butt-welding thin-walled hollow pipes, due to the very thin wall thickness of the pipes, welding deformation and welding cracks are likely to occur, resulting in unqualified assembly accuracy or even product scrapping. And the existing pipeline welding and butt-joint tools have poor stability after butt-joint welding, and it is difficult to guarantee the welding quality.

[0006] Therefore, a new type of pipeline welding equipment is proposed to solve the existing deficiencies. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a new type of pipeline welding equipment.

[0008] To solve the above technical problem, the technical solution provided by the present invention is a new type of pipeline welding equipment: including a base and a fixing part and a clamping part arranged on the base;

[0009] The clamping part is slidably arranged on the base, the fixing parts are arranged on both sides of the clamping part and are linearly arranged along the extension direction of the base, and any one of the fixing parts is slidably arranged along the extension direction of the base;

[0010] The clamping part includes a support frame and a spliced gear. The spliced gear is movably arranged inside the support frame. A limiting rod is slidably arranged above the spliced gear inside the support frame. Transmission teeth meshing with the spliced gear are arranged at the bottom of the support frame and the lower side of the limiting rod. A driving motor connected to one transmission tooth is arranged on the limiting rod.

[0011] The fixing part includes a fixing frame and a fixing semi-ring. A positioning rod is slidably arranged on the upper part of the fixing frame. Fixing semi-rings that can cooperate with each other are arranged on the inner side of the fixing frame and the lower side of the positioning rod.

[0012] An oil cylinder is further included. The oil cylinder is arranged on both sides of the fixing part fixedly arranged on the base. The telescopic ends of the oil cylinder are respectively connected to the corresponding clamping part and fixing part.

[0013] As an improvement, both the support frame and the fixing frame are U-shaped structures with openings upward.

[0014] As an improvement, limit pins are arranged at both ends of the limiting rod and the positioning rod for limiting the relative positions between the limiting rod and the support frame and between the positioning rod and the fixing frame.

[0015] As an improvement, the number of the transmission teeth is 4 and they are respectively located at the four corners of the spliced gear.

[0016] As an improvement, the fixing semi-rings that can cooperate with each other form a complete circular ring structure.

[0017] As an improvement, the circular ring structure formed by the fixing semi-rings is coaxially arranged with the spliced gear.

[0018] As an improvement, a through hole is arranged inside the spliced gear, and the diameter of the through hole is the same as the inner diameter of the circular ring structure formed by the fixing semi-rings.

[0019] The advantages of the present invention compared with the prior art are as follows:

[0020] 1. Through the movable fixing part, clamping part and the fixedly arranged fixing part, and in cooperation with the setting of the oil cylinder, the coaxial docking between the hollow pipe to be welded and the connecting pipe can be realized. The splicing process is simple and there is no need for multiple docking adjustments.

[0021] 2. Through the setting of the fixing semi-rings and the spliced gear, the fixed installation of the hollow pipe to be welded and the connecting pipe is convenient, and at the same time, the coaxiality of the hollow pipe to be welded and the connecting pipe can be ensured.

[0022] 3. Through the cooperation between the transmission teeth and the spliced gear in the clamping part, and by connecting the driving motor with the transmission teeth, the driving of the spliced gear is realized, so as to realize the rotation of the connecting hollow pipe, and further achieve the friction welding between the connecting hollow pipe and the hollow pipe to be welded.

[0023] 4. The pipeline welding equipment has a reasonable structure and is easy to use, which can effectively ensure the butt joint of the hollow pipe to be welded and the connecting pipe. At the same time, due to the use of friction welding, while ensuring the welding quality, the welding efficiency can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the objectives, technical solutions and advantages of the embodiments of the invention clearer, the technical solutions in the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are some, but not all, of the embodiments of the invention. Usually, the components of the embodiments of the invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] In the description of the embodiments of the invention, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the invention product is usually placed during use. This is only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the invention. In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0033] In addition, if terms such as "horizontal", "vertical", "hanging" are used, it does not mean that the component is required to be absolutely horizontal or hanging, but it can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and it does not mean that the structure must be completely horizontal, but it can be slightly inclined.

[0034] In the description of the embodiments of the invention, "a plurality of" means at least two.

[0035] In the description of the embodiments of the invention, it should also be noted that unless otherwise clearly specified and limited, if terms such as "set", "installed", "connected", "connected" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the invention can be understood according to specific situations.

[0036] Combined with the attached Figures 1 - 6 As shown, a new type of pipeline welding device includes a base 1, 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 the actual situation. In this embodiment, the base 1 is a rectangular plate-like structure, which is convenient to place and can also facilitate the cooperation of the device with other workbenches through the base 1.

[0037] The clamping part 3 is slidably arranged on the base 1. Specifically, a set of slideways are arranged on the base 1 along the length direction of the base 1, and sliders are arranged on the clamping part 3 to cooperate with the slideways, so that the clamping part 3 can move reciprocally on the base 1.

[0038] The fixing part 2 is arranged on both sides of the clamping part 3 and is linearly arranged along the extending direction of the base 1, and any one of the fixing parts 2 is slidably arranged along the extending direction of the base 1;

[0039] In specific implementation, the fixing part 2 is arranged on both sides of the clamping part 3. Among them, one side of the fixing part 2 located at the clamping part 3 is fixedly connected to the base 1, and the other side of the fixing part 2 is slidably matched with the base 1. Similarly, the fixing part 2 is provided with a slider matched with the slideway, and the fixing part 2 can reciprocate on the base 1.

[0040] Furthermore, through the movement of the movable fixing part 2 and the clamping part 3, the cooperation and separation between the clamping part 3 and the fixing part 2 can be realized;

[0041] The clamping part 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, and a slider is arranged at the bottom of the support frame 31, so that the clamping part 3 can reciprocate on the base 1;

[0042] The spliced gear 32 is movably arranged inside the support frame 31. Specifically, the structure of the spliced gear 32 can refer to the structure of a novel spliced gear with the application number 202420191093X. In implementation, the spliced gear 32 can fix the connecting pipe, and at the same time, the length of the connecting pipe is greater than the thickness of the spliced gear 32.

[0043] A limiting rod 33 is slidably arranged above the spliced gear 32 on the support frame 31. Specifically, the limiting rod 33 can move along the height direction of the support frame 31. By moving the support frame 31 upward, the installation and disassembly of the spliced gear 32 can be facilitated.

[0044] Furthermore, limiting pins 5 are arranged at both ends of the limiting rod 33 for limiting the position between the limiting rod 33 and the support frame 31. Through the arrangement of the limiting pins 5, the stability of the cooperation between the transmission teeth 34 on the limiting rod 33 and the spliced gear 32 can be ensured.

[0045] Driving teeth 34 meshing with the spliced gear 32 are arranged at the bottom of the support frame 31 and the lower side of the limiting rod 33. Specifically, the number of the driving teeth 34 is 4 and they are respectively located at the four corners of the spliced gear 32.

[0046] Through the arrangement of 4 driving teeth 34 meshing with the spliced gear 32, while supporting the spliced gear 32, the stability of the rotation of the spliced gear 32 can be ensured.

[0047] At the same time, in order to prevent the spliced gear 32 from axially moving, limiting rings matching the sides of the driving teeth 34 can be arranged on both sides of the spliced gear 32.

[0048] A driving motor 35 connected to one driving tooth 34 is arranged on the limiting rod 33. Through the driving of the driving motor 35 on the connected driving tooth 34, the rotation of the spliced gear 32 can be driven.

[0049] The fixing part 2 includes a fixing frame 21 and a fixing semi-ring 22. Specifically, the fixing frame 21 is a U-shaped structure with an upward opening, and a slider is arranged at the bottom of the fixing frame 21, thereby realizing the reciprocating movement of the fixing part 2 on the base 1;

[0050] A positioning rod 23 is slidably arranged on the upper part of the fixing frame 21. Further, limit pins 5 are arranged at both ends of the positioning rod 23 for limiting the relative position between the positioning rod 23 and the fixing frame 21. Through the arrangement of the limit pins 5, the cooperation between the fixing frame 21 and the fixing semi-ring 22 on the positioning rod 23 can be ensured, and the fixed clamping of the hollow pipe to be welded is realized through the cooperation of the fixing semi-ring 22;

[0051] To avoid damaging the hollow pipe to be welded during the fixing process of the fixing semi-ring 22 to the hollow pipe to be welded, a thin soft pad can be arranged on the inner side of the fixing semi-ring 22.

[0052] Fixing semi-rings 22 that can cooperate with each other are arranged on the inner side of the fixing frame 21 and the lower side of the positioning rod 23. Specifically, the fixing semi-rings 22 that can cooperate with each other form a complete circular ring structure.

[0053] During implementation, the circular ring structure formed by the fixing semi-rings 22 is coaxially arranged with the spliced gear 32. During implementation, it can be ensured that the pipeline to be welded located in the fixing part 2 and the connecting pipe located in the clamping part 3 are coaxially arranged to ensure the cooperation between the two ends of the connecting pipe and the pipeline to be welded.

[0054] A through hole 321 is arranged in the spliced gear 32. Through the arrangement of the through hole 321, the fixed clamping of the connecting pipe can be realized; the diameter of the through hole 321 is the same as the inner diameter of the circular ring structure formed by the fixing semi-rings 22 to meet the welding requirements for pipelines of the same specification.

[0055] An oil cylinder 4 is further included. In this embodiment, the oil cylinder 4 is a double-stage oil cylinder. The oil cylinder 4 is arranged on both sides of the fixing part 2 fixedly arranged on the base 1, and the telescopic ends of the oil cylinder 4 are respectively connected to the corresponding clamping part 3 and fixing part 2.

[0056] During implementation, when the fixing part 2 and the clamping part 3 need to be separated, the first-stage oil cylinder of the oil cylinder 4 first extends to push the movable fixing part 2. When the second-stage oil cylinder of the oil cylinder 4 extends, the clamping part 3 is pushed. When the fixing part 2 and the clamping part 3 need to cooperate, the first-stage oil cylinder of the oil cylinder 4 first retracts to drive the movable fixing part 2 to move towards the clamping part 3. When the movable fixing part 2 and the clamping part 3 cooperate, the second-stage oil cylinder of the oil cylinder 4 continues to retract to drive the movable fixing part 2 and the clamping part 3 to move towards the fixed fixing part 2, thereby realizing the cooperation between the fixing part 2 and the clamping part 3.

[0057] In the specific implementation of the present invention, before installation, through the elongation of the oil cylinder 4, the separation between the fixing part 2 and the clamping part 3 is realized;

[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. At the same time, place the hollow pipe to be welded in the fixed half-ring 22 on the fixing frame 21, then lower the positioning rod 23, 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 realize the fixation of the hollow pipe to be welded. Then, the positioning rod 23 and the fixing frame 21 are fixed through the limit pin 5.

[0059] At the same time, lift the limit rod 33 in the clamping part 3 and separate the split gears 32. Then place the connecting hollow pipe in the split gears 32, and at the same time complete the splicing of the split gears 32 to realize the fixation of the connecting hollow pipe. Then lower the limit rod 33 to make the driving gear 34 cooperate with the split gears 32, and the limit rod 33 and the support frame 31 are fixed through the limit pin 5.

[0060] Finally, through the contraction of the oil cylinder 4, the cooperation between the fixing part 2 and the clamping part 3 is realized, and it is ensured that the hollow pipes to be welded fixed in the fixing parts 2 on both sides of the clamping part 3 are docked with the connecting hollow pipe in the clamping part 3. Then start the driving motor 35 to realize the rotation of the split gears 32, and further drive the rotation of the connecting hollow pipe, so as to achieve friction welding between the connecting hollow pipe and the hollow pipe to be welded.

[0061] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the purpose of the present invention creation, without creative design, they design similar structural manners and embodiments to this technical solution, which should all fall within the protection scope of the present invention.
