Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically to a laser welding equipment for the production of multi-channel pipes. Background Technology

[0002] Non-insulated four-way valves are key ventilation products in ship ventilation systems, playing a crucial role in the diversion and convergence of airflow from multiple pipelines. Their structural stability and connection sealing directly affect the operational efficiency and safety of the ship ventilation system. In the manufacturing process of non-insulated four-way valves, the welding quality of the main pipe and multiple branch pipes is the core link to ensure product performance. Laser welding, with its advantages of high energy density, fast welding speed, and small heat-affected zone, has gradually become the preferred process for welding non-insulated four-way valves. This welding equipment and process is an important component in the intelligent casting system for improving the manufacturing precision and efficiency of complex metal components.

[0003] However, in the traditional non-insulated tee welding process, the positioning step often relies on manual hand-held or simple clamping methods. Due to the lack of a stable clamping structure, the main and branch pipes are prone to positional shifts and shaking during welding, directly leading to quality problems such as weld misalignment and edge displacement. This not only significantly reduces weld strength, causing structural fracture risks in the non-insulated tee during long-term use, but also damages the integrity of the internal airflow channels, increasing airflow resistance and affecting the overall operational efficiency of the ship's ventilation system. Simultaneously, laser welding generates a large amount of heat that is difficult to dissipate quickly. Slight pipe displacement caused by unstable positioning further exacerbates the uneven stress on the welded area due to high temperatures, resulting in irregular deformation and compromising the original structural precision of the pipe. Ultimately, this leads to a decline in the sealing performance of the non-insulated tee. Summary of the Invention

[0004] The purpose of this invention is to provide a laser welding device for the production of multi-channel pipes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser welding device for multi-port pipe production, comprising a base, a robotic arm mounted on the base, a laser welding machine mounted on the robotic arm, a vertical support plate mounted on the base, and further comprising:

[0006] A fixed support plate is rotatably mounted on a vertical support plate, and a fixed straight plate is fixedly mounted on the fixed support plate, and a support plate is fixedly mounted on the fixed straight plate;

[0007] A quick positioning mechanism, mounted on a fixed support plate, is used to fix and connect the main pipeline and branch pipelines;

[0008] A cooling mechanism, installed on the quick positioning mechanism, is used to cool the weld joint. The cooling mechanism includes a coolant circulation assembly installed on the quick positioning mechanism and multiple heat-conducting flat tubes connected to the coolant circulation assembly.

[0009] A flipping component, mounted on a vertical support plate and connected to a fixed support plate, is used to drive the entire structure to flip.

[0010] When the rapid positioning mechanism fixes the main pipe and drives the branch pipe to connect with the main pipe, the cooling mechanism moves along with the branch pipe, and the heat-conducting flat tube moves to the inside of the welded connection between the main pipe and the branch pipe.

[0011] Preferably, the rapid positioning mechanism includes a limiting component for fixing the main pipeline and a moving component for driving the branch pipeline to connect with the main pipeline. The limiting component includes an electric telescopic rod fixedly installed on a fixed support plate. The output end of the electric telescopic rod is connected to a movable sliding plate, and an abutment plate is fixed on the movable sliding plate.

[0012] Preferably, the moving component includes a push plate hinged to the moving slide plate, a connecting plate hinged to the end of the push plate away from the moving slide plate, a sliding support plate fixed to one end of the connecting plate, and the sliding support plate slidably connected within the fixed support plate.

[0013] Preferably, a central mounting plate is fixed on the sliding support plate, and a mounting bracket is fixedly connected to the central mounting plate via a connecting support plate. Electric push rods are symmetrically arranged on the mounting bracket, and the output end of the electric push rod is connected to a pushing arc plate.

[0014] Preferably, the sliding support plate is provided with a sliding protrusion, and the fixed support plate is provided with a sliding groove for the sliding support plate and the sliding protrusion to slide.

[0015] Preferably, the coolant circulation assembly includes a first cooling tank and a second cooling tank fixed on the mounting plate. Both the first cooling tank and the second cooling tank are connected by a connecting flat tube. The connecting flat tube is connected to a heat-conducting flat tube through multiple connecting short tubes. The multiple heat-conducting flat tubes are connected to each other by a fixed connecting column. One end of the heat-conducting flat tube is fixedly connected to a mounting column, and one end of the mounting column is connected to the mounting plate.

[0016] Preferably, the heat-conducting flat tube is disposed on the inner side of the welded connection between the main pipe and the branch pipe, and a plurality of the heat-conducting flat tubes are arranged in a straight line array along the fixed connecting column.

[0017] Preferably, the pushing arc plate has an arc-shaped structure to match the outer diameter of the branch pipe and achieve radial limiting and fixing.

[0018] Preferably, the main pipe is placed on a support plate, and the branch pipe is sleeved on the mounting column.

[0019] Preferably, the flipping assembly includes a drive motor fixedly mounted on a vertical support plate, the output end of the drive motor is connected to a worm gear, and a worm wheel meshes on the worm gear.

[0020] Preferably, one end of the worm gear is connected to a rotating column, the rotating column is rotatably connected to a vertical support plate, and the end of the rotating column away from the worm gear is fixedly connected to a fixed support plate.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting up a rapid positioning mechanism, efficient and precise docking of the main pipeline and the branch pipeline can be achieved. The limiting component pushes the moving slide plate through the electric telescopic rod, so that the abutment plate firmly clamps the main pipeline. The moving component drives the sliding support plate to move by pushing the connecting plate and the connecting folding plate, so as to achieve precise docking of the branch pipeline and the main pipeline, which greatly improves the docking accuracy and efficiency, effectively avoids problems such as weld seam offset and misalignment, and ensures the welding strength and smooth airflow inside the pipeline.

[0023] 2. The cooling mechanism is designed to cool the welding area in a timely and efficient manner. The coolant circulation component forms a circulation path through the first cooling tank, the second cooling tank, the connecting flat pipe, and the connecting short pipe, keeping the heat-conducting flat pipe at a low temperature. When the branch pipe is connected to the main pipe, the heat-conducting flat pipe is located inside the welding point, which can quickly absorb the welding heat and prevent the pipe from deforming due to high temperature, thus ensuring the structural accuracy and sealing performance of the non-insulated four-way valve.

[0024] 3. The flipping component significantly improves the convenience and comprehensiveness of multi-channel pipe welding. The flipping component can drive the fixed support plate and the pipe above to flip as a whole. When used in conjunction with the cooling mechanism, during the flipping process, the first cooling box gradually moves to the bottom of the heat-conducting flat tube, while the second cooling box moves to the top. The liquid that has absorbed heat in the heat-conducting flat tube flows into the first cooling box through the connecting short pipe and the connecting flat tube. At the same time, the coolant in the second cooling box replenishes the heat-conducting flat tube, so that the heat-conducting flat tube always maintains good cooling capacity.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 13This invention provides a technical solution: a laser welding equipment for multi-port pipe production, comprising a base 1, a robotic arm 2 mounted on the base 1, a laser welding machine 3 mounted on the robotic arm 2, a vertical support plate 4 mounted on the base 1, a fixed support plate 5 rotatably mounted on the vertical support plate 4, a fixed straight plate 10 fixedly mounted on the fixed support plate 5, and a support plate 11 fixedly mounted on the fixed straight plate 10; a rapid positioning mechanism 6 is mounted on the fixed support plate 5 for fixing and connecting the main pipe 8 and branch pipes 9; and a cooling mechanism 7 is mounted on the rapid positioning mechanism. The positioning mechanism 6 is used to cool the weld joint. The cooling mechanism 7 includes a coolant circulation assembly installed on the quick positioning mechanism 6 and multiple heat-conducting flat tubes 75 connected to the coolant circulation assembly. The flipping assembly is set on the vertical support plate 4 and connected to the fixed support plate 5 to drive the overall flipping. When the quick positioning mechanism 6 fixes the main pipe 8 and drives the branch pipe 9 to connect with the main pipe 8, the cooling mechanism 7 moves with the branch pipe 9, and the heat-conducting flat tubes 75 move to the inside of the weld joint between the main pipe 8 and the branch pipe 9.

[0041] By setting up a rapid positioning mechanism 6, efficient and precise docking of the main pipe 8 and the branch pipe 9 can be achieved. The limiting component pushes the moving slide plate 62 through the electric telescopic rod 61, so that the abutment plate 60 firmly clamps the main pipe 8. The moving component drives the sliding support plate 65 to move by pushing the connecting plate 63 and the connecting folding plate 64, so as to achieve precise docking of the branch pipe 9 and the main pipe 8. Compared with traditional manual positioning or simple tooling, the docking accuracy and efficiency are greatly improved, effectively avoiding problems such as weld seam offset and misalignment, and ensuring welding strength and smooth airflow inside the pipe. The cooling mechanism 7 is designed to cool the welding area in a timely and efficient manner. The coolant circulation component forms a circulation path through the first cooling box 71, the second cooling box 72, the connecting flat pipe 73 and the connecting short pipe 74, so that the heat-conducting flat pipe 75 is always kept at a low temperature. When the branch pipe 9 and When the main pipe 8 is connected, the heat-conducting flat tube 75 is located inside the weld joint, which can quickly absorb the welding heat and prevent the pipe from deforming due to high temperature. This ensures the structural accuracy and sealing performance of the non-insulated four-way joint. The setting of the flipping component significantly improves the convenience and comprehensiveness of welding multi-way pipes. The flipping component can drive the fixed support plate 5 and the pipe above it to flip as a whole. When used in conjunction with the cooling mechanism 7, during the flipping process, the first cooling box 71 gradually moves to the bottom of the heat-conducting flat tube 75, while the second cooling box 72 moves to the top. The liquid in the heat-conducting flat tube 75 that has absorbed heat flows into the first cooling box 71 through the connecting short pipe 74 and the connecting flat tube 73. At the same time, the coolant in the second cooling box 72 is replenished to the heat-conducting flat tube 75, so that the heat-conducting flat tube 75 always maintains good cooling capacity and avoids the problem of affecting the weld quality due to cooling interruption caused by flipping welding.

[0042] In actual production, to ensure docking accuracy, the marking line alignment method commonly used in existing technology is adopted. A first marking line is pre-set along the length of the main pipe 8, and a first alignment line is set on the fixed straight plate 10. When the main pipe 8 is placed on the support plate 11, the first marking line and the first alignment line are completely aligned by adjusting the circumferential angle of the main pipe 8. With the positional correlation between the two, the two weld holes of the main pipe 8 can be accurately positioned horizontally, laying the foundation for the subsequent docking of the branch pipe 9. Similarly, a second marking line is pre-set along the length of the branch pipe 9, and a second alignment line is set on the connecting flat pipe 73. When the branch pipe 9 is fitted onto the mounting column 77, the second marking line and the second alignment line are accurately aligned by adjusting the circumferential angle of the branch pipe 9, so as to achieve precise positioning of the branch pipe 9, ensure that the branch pipe 9 is perpendicular to the main pipe 8, and accurately dock the arc welds of the two.

[0043] like Figures 5 to 8 As shown, the quick positioning mechanism 6 includes a limiting component for fixing the main pipe 8 and a moving component for driving the branch pipe 9 to connect with the main pipe 8. The limiting component includes an electric telescopic rod 61 bolted to a fixed support plate 5. The output end of the electric telescopic rod 61 is connected to a movable slide plate 62. An abutment plate 60 is welded and fixed to the movable slide plate 62. The moving component includes a pushing connecting plate 63 hinged to the movable slide plate 62. A connecting folding plate 64 is hinged to the end of the pushing connecting plate 63 away from the movable slide plate 62. A sliding support plate 65 is welded and fixed to one end of the connecting folding plate 64. The sliding support plate 65 is slidably connected to the fixed support plate 612. A middle mounting plate 67 is welded and fixed on the sliding support plate 65. A mounting support plate 69 is welded and fixed on the middle mounting plate 67 through a connecting support plate 68. Electric push rods 610 are symmetrically arranged on the mounting support plate 69 and fixedly installed by bolts. A pushing arc plate 611 is bolted to the output end of the electric push rod 610. A sliding protrusion 66 is welded on the sliding support plate 65. A sliding groove 613 is opened on the fixed support plate 612 for the sliding support plate 65 and the sliding protrusion 66 to slide.

[0044] When the electric telescopic rod 61 in the limiting assembly pushes the movable slide plate 62 to move, the movable slide plate 62 will drive the push connecting plate 63 to move synchronously. The push connecting plate 63 transmits the force to the sliding support plate 65 through the hinge relationship with the connecting folding plate 64, so that the sliding support plate 65 slides smoothly along the sliding groove 613 on the fixed support plate 612. The cooperation between the sliding protrusion 66 and the sliding groove 613 can effectively prevent the sliding support plate 65 from tilting or deviating during the sliding process, ensuring the stability of the movement.

[0045] Simultaneously, the mounting plate 69 moves closer to the main pipe 8 under the action of the sliding support plate 65. After the branch pipe 9 is fitted onto the mounting column 77, the electric push rod 610 starts and pushes the arc plate 611 to clamp and fix the branch pipe 9 from both sides. The arc-shaped pushing arc plate 611 can perfectly fit with the outer wall of the branch pipe 9, improving the firmness of the branch pipe 9. Subsequently, under the continuous action of the moving component, the branch pipe 9 is accurately pushed to the docking position with the main pipe 8, realizing the rapid and accurate docking of the main pipe 8 and the branch pipe 9.

[0046] like Figures 7 to 9 As shown, the coolant circulation assembly includes a first cooling tank 71 and a second cooling tank 72 welded and fixed to the mounting plate 69. Both the first cooling tank 71 and the second cooling tank 72 are connected by a connecting flat pipe 73. The connecting flat pipe 73 is connected to a heat-conducting flat pipe 75 via multiple connecting short pipes 74. The multiple heat-conducting flat pipes 75 are welded and fixed together by fixing columns 76. One end of each heat-conducting flat pipe 75 is welded and fixedly connected to a mounting column 77, and one end of the mounting column 77 is welded and fixed to the mounting plate 69. The heat-conducting flat pipe 75 is located inside the welded connection between the main pipe 8 and the branch pipe 9. Furthermore, multiple heat-conducting flat tubes 75 are arranged in a straight array along the fixed connecting column 76. The multiple heat-conducting flat tubes 75 arranged in a straight array along the fixed connecting column 76 can fully cover the inner side of the welding connection between the main pipe 8 and the branch pipe 9, greatly increasing the cooling area. The fixed connecting column 76 fixes the heat-conducting flat tubes 75, ensuring their structural stability during the movement of following the branch pipe 9 and during the welding process. When the laser welding machine 3 welds the connection, the high temperature will be quickly conducted to the surrounding area of ​​the welding point. At this time, the coolant in the heat-conducting flat tubes 75 can quickly absorb the heat, thereby reducing the temperature of the welding point.

[0047] like Figures 3 to 7 As shown, the pushing arc plate 611 has an arc-shaped structure to match the outer diameter of the branch pipe 9 and achieve radial limiting and fixing. The main pipe 8 is placed on the support plate 11, and the branch pipe 9 is sleeved on the mounting column 77. The flipping assembly includes a drive motor 14 that is fixedly mounted on the vertical support plate 4 by bolts. The drive motor 14 is a model with forward and reverse rotation function and precise speed control in the prior art. Specifically, it can be a Panasonic MSMD042G1U servo motor. It is fixed to the vertical support plate 4 by bolts to ensure that it will not loosen due to vibration during operation. The output end of the drive motor 14 is connected to a worm gear 13 through a coupling. A worm wheel 12 meshes on the worm gear 13. A rotating column 15 is welded and fixed to one end of the worm wheel 12. The rotating column 15 is rotatably connected to the vertical support plate 4. The end of the rotating column 15 away from the worm wheel 12 is welded and fixed to the fixed support plate 5.

[0048] After the upper side welding is completed, the drive motor 14 drives the worm gear 13 to rotate, the worm gear 13 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the fixed support plate 5 to rotate through the rotating column 15, realizing the overall flipping of the main pipe 8 and the branch pipe 9, so that the other side of the connection can be welded. The flipped state is as follows. Figure 13 As shown, during the flipping process, the first cooling box 71 gradually moves to the bottom of the heat-conducting flat tube 75, while the second cooling box 72 moves to the top of the heat-conducting flat tube 75. The liquid that has absorbed heat in the heat-conducting flat tube 75 flows into the first cooling box 71 through the connecting short tube 74 and the connecting flat tube 73. At the same time, the coolant in the second cooling box 72 is replenished to the heat-conducting flat tube 75.

[0049] In actual operation, the main pipe 8 is first placed on the support plate 11, and the branch pipe 9 is fitted onto the mounting column 77. Then, the electric push rod 610 is activated, which drives the arc plate 611 to limit and fix the branch pipe 9. Next, the two electric telescopic rods 61 are activated, driving the movable slide plate 62 to slide on the fixed straight plate 10. The movable slide plate 62 drives the abutment plate 60 to approach and contact the main pipe 8, thereby stabilizing the main pipe 8 on the support plate 11. During this process, the movement of the movable slide plate 62 will push the connecting plate. 63 drives the connecting folding plate 64 to move, and the connecting folding plate 64 in turn drives the sliding support plate 65 and the sliding protrusion 66 to slide in the sliding groove 613. Then, through the transmission of the middle mounting plate 67, the connecting support plate 68 and the mounting support plate 69, the branch pipe 9 moves closer to the main pipe 8 and achieves precise docking. After that, the robotic arm 2 drives the laser welding machine 3 to weld the connection between the main pipe 8 and the branch pipe 9. At this time, the coolant in the heat-conducting flat tube 75 located inside the connection will absorb the heat generated by welding to ensure the temperature of the welding area is stable.

[0050] After the upper side welding is completed, the drive motor 14 drives the worm gear 13 to rotate, the worm gear 13 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the fixed support plate 5 to rotate through the rotating column 15, realizing the overall flipping of the main pipe 8 and the branch pipe 9, so that the other side of the connection can be welded. The flipped state is as follows. Figure 13 As shown, during the flipping process, the first cooling box 71 gradually moves to the bottom of the heat-conducting flat tube 75, while the second cooling box 72 moves to the top of the heat-conducting flat tube 75. The liquid that has absorbed heat in the heat-conducting flat tube 75 flows into the first cooling box 71 through the connecting short tube 74 and the connecting flat tube 73. At the same time, the coolant in the second cooling box 72 is replenished to the heat-conducting flat tube 75 to ensure a continuous and effective cooling effect.
