Detailed Implementation
[0026] 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.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] In the field of composite material manufacturing, reliable connection of tubular components is a critical aspect of many industrial applications, particularly in aerospace structures, specialty chemical pipelines, and high-end sports equipment. Welding, as one of the main methods for achieving permanent joints at pipe ends, directly impacts weld quality and structural integrity through equipment performance. Currently, there are various types of equipment available for welding composite material pipes, which can be broadly categorized based on their level of automation into manual operation, semi-automatic assisted operation, and fully automatic integrated systems. Manual equipment heavily relies on operator experience for pipe positioning and welding trajectory control, resulting in limited efficiency and inconsistent performance. More automated equipment, on the other hand, uses mechanical structures to achieve precise clamping, centering, rotation, and welding torch movement of the pipes.
[0029] A typical composite pipe welding machine is usually built on a stable workbench or frame, which provides rigid support for the entire system. The workbench surface is often equipped with linear guides or precision grooves to guide the smooth movement of critical moving components. One of the core functional modules of the equipment is the clamping and rotating mechanism, whose primary task is to securely hold the two pipe sections to be welded and ensure precise coaxial alignment of their mating ends. Common clamping methods include external chuck clamps that apply uniform pressure from the outside of the pipe, with the inner sides of the jaws often lined with elastic rubber or engineering plastic protective layers to prevent damage to the pipe surface; for large-diameter pipes, internal expansion clamps with internal expansion support may be used; some complex designs combine two methods to form a combined clamping system to enhance stability. These clamps are usually connected to a rotary drive unit such as a servo motor, enabling the clamped pipe to rotate uniformly around its central axis, a fundamental condition for achieving continuous and uniform circumferential welding.
[0030] The welding torch system is another core component, responsible for precisely guiding the heat source to the welding area. Depending on the properties of the composite matrix, the heat source may be a laser beam, high-frequency ultrasound, resistance heating, or controlled hot air. The welding torch body is typically mounted on a multi-directionally adjustable slide or controlled by a robotic arm, giving it the necessary degrees of freedom of movement. This includes the ability to adjust its position along the length of the pipe (axial direction) to align with the weld initiation point and follow the welding path; the ability to control the distance between the welding torch and the outer surface of the pipe (radial direction) to ensure the maintenance of the optimal welding distance; and the ability to adjust the angle or working angle of the welding torch relative to the weld. These adjustments are typically achieved using manual lead screws, electric actuators, or ball screws driven by servo motors in conjunction with linear guides to ensure positioning accuracy.
[0031] To support longer pipes and reduce bending deformation during rotation, equipment is often equipped with auxiliary support structures that can be adjusted along the length of the pipe, such as free-rolling support wheels or V-shaped positioning blocks. For clamping slides or welding torch slides that require axial movement, high-precision linear guides and slider assemblies are key elements to ensure smooth movement and repeatability. In automated equipment, the control system, such as a programmable logic controller (PLC) or industrial computer, is responsible for coordinating the sequence of actions of various actuators, including precisely setting and monitoring the rotational speed of the pipe, the moving speed of the welding torch, and core parameters during the welding process such as temperature, pressure, and duration.
[0032] Despite advancements in automation, significant challenges remain when addressing specific working conditions, particularly when welding two composite pipe sections of significantly different lengths. Many welding devices are designed based on symmetry, employing single-through lead screws or synchronous belt drives to simultaneously move the clamping slides on both sides at equal distances, either towards or away from each other. This design is effective for welding pipes of equal length, ensuring the mating ends always converge at a predetermined fixed position (e.g., center point) on the worktable, requiring only the welding torch to be positioned at that point. However, when one pipe is significantly shorter than the other, this symmetrical drive mechanism can cause the shorter pipe's end face to fail to reach the predetermined welding position, while the longer pipe's end face will extend beyond that point, resulting in misalignment of the mating ends within the welding torch's effective adjustment range. Requiring an excessively large axial travel of the welding torch to accommodate various length combinations in this situation not only significantly increases equipment complexity and cost but may also affect the overall system rigidity and positioning accuracy.
[0033] Precise positioning of the welding torch is inherently complex. When the mating point deviates significantly from the equipment's center due to differences in pipe length, operators need to frequently perform multiple steps of unlocking, moving, and relocking the welding torch. This process is time-consuming and prone to human error, particularly detrimental to fields requiring high-precision welding, such as aerospace. Ideally, the equipment should be able to independently and flexibly control the positions of the fixed-end clamp, the movable-end clamp, and the welding torch. The fixed end stabilizes the reference pipe (usually a longer or more immobile section), the movable end pushes and presses the other pipe section into the mating position, and the welding torch precisely tracks the weld seam. However, in existing designs, achieving a truly independent, non-interfering, and easy-to-operate adjustment mechanism for these three components often faces difficulties. Arranging complex transmission mechanisms or relying on multiple independent drive motors within a compact space increases manufacturing costs and the complexity of the control system.
[0034] Some solutions designed to accommodate length variations, such as extending the guide rail or increasing the adjustment stroke, may sacrifice the overall structural rigidity of the equipment. Reduced rigidity increases the risk of vibration during welding, thus affecting weld quality. Simultaneously, complex adjustment procedures, such as requiring manual switching of drive connection points or operation of multiple adjustment handles, reduce ease of use, increase operator workload, and raise the possibility of misoperation. Therefore, within the existing technological framework, balancing adjustment flexibility, operational convenience, structural stability, and cost-effectiveness, especially in the specific application of efficiently welding non-uniform length composite pipes, remains a key issue that urgently needs optimization and resolution in equipment development. This necessitates exploring more ingenious and reliable mechanical structure designs to achieve rapid, independent, and precise adjustment of the movable clamping components and welding torch position, ensuring that the welding heat source consistently and efficiently acts on the changing butt joint face position.
[0035] Please see Figure 1-3 As shown, this embodiment provides a composite material welding device, including: a workbench 1, a fixed support, a rectangular frame 25, a movable support and a welding assembly slidably fitted on the upper side of the workbench 1, the movable support being located between the rectangular frame 25 and the fixed support, and the welding assembly being located between the movable support and the fixed support.
[0036] The workbench 1 has two slide grooves 12 on its upper side and two first gears 15 rotatably engaged on one side. A rectangular frame 25 is located between the two slide grooves 12. A screw 13 is installed at one end of the first gear 15 and passes through the corresponding slide groove 12 laterally. The bottom of the movable support and welding assembly is equipped with a slider 14, which slides in the corresponding slide groove 12 and is threaded around the corresponding screw 13. The rectangular frame 25 has an inverted U-shaped channel 23 laterally, and a movable seat 5 slides in the inverted U-shaped channel 23. An adjustment handle 21 is installed on one side of the movable seat 5, and a second gear 20 is rotatably engaged around the adjustment handle 21. The second gear 20 meshes with one of the first gears 15. An eccentric handle 22 is installed on one end face of the second gear 20 and is located on the side of the adjustment handle 21. Limiting parts corresponding to the movable seat 5 are elastically slidable on both sides of the rectangular frame 25.
[0037] One application of this embodiment is as follows: In use, firstly, rotating the eccentric handle 22 drives the second gear 20 to rotate. The rotation of the second gear 20 drives the first gear 15 meshing with it to rotate. The rotation of the first gear 15 drives the corresponding screw 13 to rotate. The rotation of the screw 13 drives the slider 14, which is threaded to its periphery, to slide along the slide groove 12. Thus, the slider 14 drives the movable support to adjust its position. After adjustment, pull the corresponding limiting member to release its restriction on the moving seat 5. Then, hold the adjusting handle 21 and move the moving seat 5 up, down, and forward sequentially along the inverted U-shaped groove 23, so that the second gear 20 meshes with another first gear 15. The other limiting member then re-limits the moving seat 5. Finally, rotating the eccentric handle 22 adjusts the position of the welding assembly. It should be noted that all electrical devices involved in this application can be powered by a battery or an external power source.
[0038] The sliding groove 12 improves the stability of the sliding of the slider 14 and, in conjunction with the screw 13, facilitates the position adjustment of the movable support and welding components. The limiting component facilitates the limiting and fixing of the adjusted movable seat 5, improving the stability of the meshing transmission between the second gear 20 and the first gear 15. In conjunction with the inverted U-shaped channel 23 and the adjusting handle 21, it facilitates the quick switching of the meshing object of the second gear 20, realizing the separate adjustment of the movable support and welding components at a single operating point, improving the convenience of device adjustment, and reducing the impact of the length difference between the two composite material tubes 27 on the welding quality.
[0039] like Figure 3 As shown, in this embodiment, a limiting channel 24 is provided on the inner wall of the inverted U-shaped channel 23, and a limiting frame 6 corresponding to the inverted U-shaped channel 23 is installed on the periphery of the movable seat 5. The lower side and both sides of the limiting frame 6 are located in the limiting channel 24, and one of the limiting members is located on the upper side of the limiting frame 6. By cooperating with the limiting channel 24 and the limiting frame 6, the stability of the movable seat 5 sliding in the inverted U-shaped channel 23 is improved, and the probability of the movable seat 5 disengaging from the inverted U-shaped channel 23 is reduced.
[0040] like Figure 3 As shown, the limiting component in this embodiment includes a connecting rod 17 that slides elastically on a rectangular frame 25. The two ends of the connecting rod 17 are respectively equipped with handles 16 and right-angled trapezoidal blocks 18. The rectangular frame 25 is located between the two handles 16. The right-angled trapezoidal blocks 18 correspond to the limiting frame 6. The tip of the right-angled trapezoidal blocks 18 is located in the limiting channel 24. One of the right-angled trapezoidal blocks 18 is located on the upper side of the limiting frame 6. Through the inclined surface design of the right-angled trapezoidal blocks 18, it is convenient to squeeze the right-angled trapezoidal blocks 18 to avoid displacement when the limiting frame 6 moves down. After the limiting frame 6 moves down to the position, the elastic force makes the right-angled trapezoidal blocks 18 quickly reset to prevent the limiting frame 6 from moving up, thereby improving the convenience of adjusting the position of the moving seat 5.
[0041] like Figure 3 As shown, the rectangular frame 25 in this embodiment has round holes on both sides. The connecting rod 17 passes through the round holes laterally. One end face of the round hole has a storage groove that communicates with the limiting groove 24. The right-angled trapezoidal block 18 is located in the storage groove on the side near the connecting rod 17. A spring is provided between the right-angled trapezoidal block 18 and one side of the storage groove. The spring is sleeved on the periphery of the connecting rod 17. The storage groove accommodates the retraction of the right-angled trapezoidal block 18 after being squeezed or pulled, reducing the probability that the right-angled trapezoidal block 18 will interfere with the movement of the limiting frame 6. The spring sleeved on the periphery of the connecting rod 17 reduces the probability that the spring will be squeezed, deflected or bent by the right-angled trapezoidal block 18.
[0042] like Figure 1As shown, in this embodiment, the adjusting handle 21 is equipped with a first bearing on its circumference, the second gear 20 is equipped with a second gear on its circumference, and the screw 13 is equipped with two second bearings on its circumference. The two second bearings are respectively embedded in the two sides of the corresponding slide groove 12. The slider 14 is located between the two second bearings. The first bearing reduces the friction between the second gear 20 and the adjusting handle 21 when it rotates. The second bearing supports both ends of the screw 13, reducing the friction between the screw 13 and the worktable 1 when it rotates.
[0043] like Figure 1 As shown, the welding assembly in this embodiment includes a slide table 7, which is mounted on the upper side of the corresponding slider 14. An L-shaped seat 8 is mounted on the upper side of the slide table 7, and a cylinder 9 is mounted on the upper side of the L-shaped seat 8. The output shaft of the cylinder 9 extends vertically through one end of the upper part of the L-shaped seat 8. A welding torch 26 is fixedly connected to the output shaft of the cylinder 9. The welding torch 26 is driven to move vertically by the cylinder 9, which facilitates the adjustment of the position and height of the welding torch 26 according to the diameter of the composite material tube 27.
[0044] like Figure 1 , 2 As shown, a metal support base 10 is installed on the upper side of the slide table 7 in this embodiment. The metal support base 10 is located on one side of the lower part of the L-shaped base 8. A receiving box 11 is provided above the metal support base 10. Multiple magnetic sheets 19 are installed on the lower side of the receiving box 11 and are magnetically attracted to the upper side of the metal support base 10. The magnetic sheets 19 are attracted and fixed to the metal support base 10, which facilitates the quick assembly and disassembly of the receiving box 11. The receiving box 11 facilitates the collection of welding slag generated during welding.
[0045] like Figure 1 , 2 As shown, the fixed support in this embodiment includes a fixed plate 2 mounted on the upper side of the workbench 1, and a movable support includes a movable plate 3 mounted on the upper side of the corresponding slider 14. Motors 4 are mounted on the opposite outer sides of the upper parts of both the fixed plate 2 and the movable plate 3. The output shaft of the motor 4 passes laterally through the corresponding fixed plate 2 or movable plate 3. A turntable 28 is fixedly connected to the output shaft of the motor 4. The turntable 28 is located between the fixed plate 2 and the movable plate 3. A protruding post 29 is provided on one end face of the turntable 28, and three electric push rods 3 are mounted on the side of the protruding post 29. 0. The output shaft of the electric push rod 30 is fixedly connected to a clamping rod 31. The surface of the clamping rod 31 is covered with a rubber sleeve 32. The electric push rod 30 extends and retracts to move the clamping rod 31, which facilitates the use of the three clamping rods 31 to clamp the composite material tube 27 externally or internally. The motor 4 drives the turntable 28, the protrusion 29, the electric push rod 30 and the clamping rod 31 to rotate, which facilitates the adjustment of the welding angle of the composite material tube 27. The rubber sleeve 32 covers the clamping rod 31 to reduce the probability of the clamping rod 31 causing damage to the surface of the composite material tube 27.
