Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a dynamic compensation welding device for adaptive pressing of curved aluminum plates. Background Technology

[0002] When welding two identical curved aluminum plates with regular shapes, it is necessary to fix the curved aluminum plates. Since the curvature of the curved aluminum plates varies, it is difficult to provide support for the inner surface of the curved aluminum plates. When using support tools with fixed shapes to support the curved aluminum plates, support tools with different diameters are required for curved aluminum plates with different curvatures. Changing support tools is quite troublesome. Moreover, the temperature rises during the welding of curved aluminum plates. Inadequate support for the inner surface of the curved aluminum plates can easily cause the curved aluminum plates to deform due to stress when heated, resulting in unqualified curved aluminum plates.

[0003] The defects of existing welding equipment are:

[0004] Existing technology CN118321798B discloses a curved panel welding mechanism for shipbuilding. This technology includes a base for supporting the entire device; a horizontal butt joint assembly, disposed inside the base, for laterally butt jointing the curved panels; two symmetrically arranged diameter adjustment assemblies, used in conjunction with the horizontal butt joint assembly, for clamping and fixing the curved panels; a support plate, disposed inside the diameter adjustment assembly, for supporting the curved panels; a longitudinal butt joint assembly, located inside the diameter adjustment assembly, used in conjunction with the diameter adjustment assembly for longitudinally butt jointing two curved panels; and a thickness adjustment assembly disposed at the output end of the longitudinal butt joint assembly. This invention improves welding efficiency by combining horizontal and vertical butt jointing and welding, and can be adjusted according to the size, thickness, length, and width of the curved panels, thus solving the problems of limited applicability and single splicing direction in existing technologies.

[0005] The aforementioned technologies require adjusting the positions of multiple rolling rods when supporting and fixing curved panels, which is a complex process. Furthermore, the technology cannot quickly adjust itself to provide effective support for the inner surfaces of curved panels with varying curvatures as the panel's curvature changes. Additionally, the supporting and clamping forces of the aforementioned technologies are difficult to control effectively, and the curved panels are prone to deformation when heated. Therefore, a dynamic compensation welding device for adaptive clamping of aluminum plate curved surfaces is needed to quickly support and fix curved panels with different curvatures while preventing thermal deformation. Summary of the Invention

A lifting rod is installed on the top input end of the pressure sensor, one end of the lifting rod extends out of the top of the guide ring, and a support plate is installed on one end of the lifting rod.

[0012] Preferably, multiple electric telescopic rods are symmetrically installed at the bottom of the first plate, and the electric telescopic rods are electrically connected to the controller. A push rod is installed at the output end of the electric telescopic rod, and a top rod is installed at one end of the push rod, with the top rod located between the first plate and the elastic plate.

[0013] Preferably, the welding mechanism includes a second movable plate, a third hydraulic cylinder, a second piston rod, a lifting block, a laser welding head, and a laser rangefinder. The left side of the second movable plate is connected to one end of the first piston rod. The third hydraulic cylinder is installed on the top of the second movable plate and is electrically connected to the controller. The second piston rod is installed at the output end of the third hydraulic cylinder. The lifting block is installed at one end of the second piston rod. The laser welding head is installed on the right side of the lifting block and is electrically connected to the controller. Laser rangefinders are symmetrically installed at the bottom of the second movable plate and are electrically connected to the controller.

[0014] Preferably, a second plate is symmetrically installed on the right side of the upright plate, a connecting rod is installed at the bottom of the second plate, multiple cameras are installed at the bottom of the second plate, and the cameras are electrically connected to the controller. A rod body is installed at one end of the connecting rod, multiple heat dissipation plates are installed at the bottom of the rod body, and thermally conductive silicone pads are installed at the bottom of the heat dissipation plates.

[0015] Preferably, multiple cylinders are installed at the bottom of the rod body. The cylinders are electrically connected to the controller. A piston rod three is installed at the output end of the cylinder. A guide ring two is movably installed on the outer side of the piston rod three.

The infrared thermometer is electrically connected to the controller.

[0016] Preferably, the method of using the aluminum plate curved surface adaptive pressing dynamic compensation welding device is as follows:

[0017] S1. Place two identical curved aluminum plates on top of the support plate in a close-fitting manner, then move the top rod up to lift the elastic plate, making the elastic plate arch. Then, the hydraulic cylinder drives the moving plate to move inward, so that the elastic plate is kept in an arched state, and the tops of multiple support plates contact the inner surface of the curved aluminum plate, thereby supporting the inner surface of the curved aluminum plate.

[0018] S2. When the elastic plate arches up, the top of the curved aluminum plate comes into contact with the thermally conductive silicone sheet. Then, the cylinder drives the second pressure plate to move down and press the top of the curved aluminum plate. The second tension and pressure sensor detects the pressure of the second pressure plate on the upper surface of the curved aluminum plate to ensure that the pressure of the second pressure plate on the curved aluminum plate is at an appropriate value.

[0019] S3. Subsequently, the laser welding head moves left and right to weld the joint of the two curved aluminum plates. At the same time, the laser rangefinder detects its distance from the curved aluminum plate, so that the laser welding head can weld the curved aluminum plate at a suitable distance. When the laser welding head welds the curved aluminum plate, the heat of the curved aluminum plate is transferred to the thermal conductive silicone pad, and the thermal conductive silicone pad transfers the heat to the heat sink for heat dissipation.

[0020] Preferably, step S3 further includes the following steps:

[0021] S31. The infrared thermometer detects the local temperature on the surface of the curved aluminum plate. When the local temperature rises to the set value, the cylinder in that area moves the pressure plate two upward to prevent the pressure plate two from pressing the high-temperature curved aluminum plate and causing deformation of the curved aluminum plate.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention involves placing two identical curved aluminum plates close together on top of a support plate, then moving a top rod upwards to lift the elastic plate, causing it to arch. Subsequently, a hydraulic cylinder drives a moving plate to move inwards, thus keeping the elastic plate in an arched state. This also ensures that the tops of multiple support plates contact the inner surface of the curved aluminum plates, facilitating the support of the inner surface of regularly shaped curved aluminum plates of different diameters.

[0024] 2. The present invention uses multiple support plates whose tops all contact the inner surface of the curved aluminum plate, thereby facilitating the support of the inner surface of the curved aluminum plate. At the same time, each pressure sensor detects the pressure of the curved aluminum plate on each support plate, making it easy to analyze whether the support plates provide effective support for the inner surface of the curved aluminum plate. This avoids the curved aluminum plate deforming under gravity when the welding of the curved aluminum plate cover is heated due to insufficient support from the support plates.

[0025] 3. The present invention uses a thermally conductive silicone pad on the upper surface of a curved aluminum plate. During the welding process of the curved aluminum plate, the heat generated during the welding process is quickly transferred to all parts of the curved aluminum plate. The heat of the curved aluminum plate is transferred to the thermally conductive silicone pad, and then the thermally conductive silicone pad transfers the heat to the heat dissipation plate. The heat dissipation plate dissipates the heat, thereby achieving rapid heat dissipation of the curved aluminum plate and reducing the possibility of deformation of the curved aluminum plate at high temperatures.

[0026] 4. The present invention uses an infrared thermometer to detect the local temperature of the curved aluminum plate surface. When the local temperature rises to a set value, the cylinder in that area drives the second pressure plate to move upward, so as to avoid the second pressure plate pressing on the high temperature curved aluminum plate and causing deformation of the curved aluminum plate.

[0043] Furthermore, plate 1 provides an installation position for other components of the equipment, support column 2 provides support for plate 1, hydraulic cylinder 4 drives moving plate 5 to move inward, thereby driving block 6, rotating rod 7 and frame 8 to move inward, the distance between the two frames 8 on the left and right decreases, thereby causing the elastic plate 9 located inside the frame 8 to bend. When the elastic plate 9 bends outward, it can provide support for the inner surface of the curved aluminum plate located above the support plate 15, so that each support plate 15 contacts and supports the inner surface of the curved aluminum plate. Bolt 10 drives pressure plate 11 to move down by rotating, thereby pressing the elastic plate 9 with pressure plate 11 to prevent the elastic plate 9 from falling off the inside of the frame 8.

[0044] Please see Figure 1 , Figure 5 and Figure 6One embodiment of the present invention provides a dynamic compensation welding device for adaptive pressing of curved aluminum plates. A vertical plate 19 is mounted on the top of the plate body 1. A hydraulic cylinder 20 is mounted on the left side of the vertical plate 19 and is electrically connected to a controller 3. A piston rod 21 is mounted on the output end of the hydraulic cylinder 20. A welding mechanism is provided at one end of the piston rod 21. The welding mechanism includes a moving plate 22, a hydraulic cylinder 23, a piston rod 24, a lifting block 25, a laser welding head 26, and a laser rangefinder 27. The left side of the second plate 22 is connected to one end of the piston rod 21. The top of the second plate 22 is equipped with a hydraulic cylinder 23, which is electrically connected to the controller 3. The output end of the hydraulic cylinder 23 is equipped with a piston rod 24. One end of the piston rod 24 is equipped with a lifting block 25. The right side of the lifting block 25 is equipped with a laser welding head 26, which is electrically connected to the controller 3. The bottom of the second plate 22 is symmetrically equipped with a laser rangefinder 27, which is electrically connected to the controller 3.

[0045] Furthermore, the upright plate 19 provides an installation position for the hydraulic cylinder 20 and the plate 28. The controller 3 controls the hydraulic cylinder 20 to move the piston rod 21 left and right, which in turn moves the moving plate 22, the hydraulic cylinder 23, the piston rod 24, the lifting block 25, the laser welding head 26, and the laser rangefinder 27 left and right. This allows the laser welding head 26 to move left and right to weld the two curved aluminum plates. The hydraulic cylinder 23 moves the piston rod 24 up and down, which in turn moves the laser welding head 26 up and down to adjust the distance between it and the upper surface of the curved aluminum plate, thus welding the surfaces of the curved aluminum plates at different heights. The laser rangefinder 27 detects its own distance from the upper surface of the curved aluminum plate, making it easy to confirm the distance between the laser welding head 26 and the upper surface of the curved aluminum plate.

[0046] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An embodiment of the present invention provides: an adaptive pressing dynamic compensation welding device for aluminum plate curved surface, wherein multiple guide rings 12 are symmetrically installed on the top of the elastic plate 9, pressure sensors 13 are installed on the bottom inner wall of the guide rings 12, and the pressure sensors 13 are electrically connected to the controller 3, and a lifting rod 14 is installed on the top input end of the pressure sensor 13, one end of the lifting rod 14 extends out of the top of the guide rings 12, and a support plate 15 is installed on one end of the lifting rod 14;

[0047] Furthermore, when the elastic plate 9 arches upward, multiple support plates 15 simultaneously contact the inner surface of the curved aluminum plate. At the same time, each pressure sensor 13 detects the pressure of the curved aluminum plate on each support plate 15, which facilitates analysis of whether the support plates 15 provide effective support to the inner surface of the curved aluminum plate. The guide ring 12 can provide guidance for the lifting rod 14, so that the lifting rod 14 can only move up and down inside the guide ring 12.

[0048] Please see Figure 1 , Figure 2 and Figure 7 An embodiment of the present invention provides: an adaptive pressing dynamic compensation welding device for aluminum plate curved surface, wherein multiple electric telescopic rods 16 are symmetrically installed at the bottom of plate body 1, and the electric telescopic rods 16 are electrically connected to the controller 3. A push rod 17 is installed at the output end of the electric telescopic rod 16, and a top rod 18 is installed at one end of the push rod 17, and the top rod 18 is located between plate body 1 and elastic plate 9.

[0049] Furthermore, the controller 3 controls the electric telescopic rod 16 to work, which drives the push rod 17 to move up and down, thereby driving the top rod 18 to move up and down. The top rod 18 moves upward to lift the elastic plate 9, ensuring that the elastic plate 9 arches upward.

[0050] Please see Figure 1 , Figure 5 and Figure 8 An embodiment of the present invention provides: an adaptive pressing dynamic compensation welding device for curved aluminum plate, wherein a second plate 28 is symmetrically installed on the right side of the upright plate 19, a connecting rod 29 is installed at the bottom of the second plate 28, a plurality of cameras 30 are installed at the bottom of the second plate 28, and the cameras 30 are electrically connected to the controller 3, a rod body 31 is installed at one end of the connecting rod 29, a plurality of heat dissipation plates 32 are installed at the bottom of the rod body 31, and a thermally conductive silicone sheet 33 is installed at the bottom of the heat dissipation plate 32;

[0051] Furthermore, plate 28 provides an installation position for connecting rod 29 and camera 30. Camera 30 captures images of the curved aluminum plate and transmits the image information to controller 3 to facilitate monitoring of the welding process of laser welding head 26 on the curved aluminum plate. Rod 31 provides an installation position for heat dissipation plate 32 and cylinder 34. When elastic plate 9 arches, the curved aluminum plate is raised, so that the upper surface of the curved aluminum plate contacts thermally conductive silicone sheet 33. During the welding process of the curved aluminum plate, the heat generated during the welding process is quickly transferred to all parts of the curved aluminum plate. The heat of the curved aluminum plate is transferred to thermally conductive silicone sheet 33, and then thermally conductive silicone sheet 33 transfers the heat to heat dissipation plate 32. Heat dissipation plate 32 dissipates the heat, realizing rapid heat dissipation of the curved aluminum plate and reducing the possibility of deformation of the curved aluminum plate at high temperature.

[0052] Please see Figure 1 , Figure 5 , Figure 8 , Figure 9 , Figure 10 and Figure 11 An embodiment of the present invention provides: an adaptive pressing dynamic compensation welding device for curved aluminum plates, wherein multiple cylinders 34 are installed at the bottom of the rod 31, the cylinders 34 are electrically connected to the controller 3, a piston rod 35 is installed at the output end of the cylinder 34, a guide ring 36 is movably installed on the outer side of the piston rod 35, an mounting plate 40 is installed at one end of the piston rod 35, a tension and pressure sensor 41 is installed at the bottom of the mounting plate 40, and the bottom input end of the tension and pressure sensor 41 is connected to the bottom inner wall of the guide ring 36, the tension and pressure sensor 41 is electrically connected to the controller 3, a pressure plate 37 is installed at the bottom of the guide ring 36, mounting blocks 38 are symmetrically installed on the top of the pressure plate 37, an infrared thermometer 39 is installed on the right side of the mounting block 38, and the infrared thermometer 39 is electrically connected to the controller 3;

[0053] Furthermore, when the curved aluminum plate is placed above the support plate 15, the controller 3 controls the cylinder 34 to work, driving the piston rod 35 to move downward. The downward movement of the piston rod 35 causes the guide ring 36 and the pressure plate 37 to move downward. The pressure plate 37 presses and fixes the curved aluminum plate. At the same time, the tension and pressure sensor 41 detects the pressure of the pressure plate 37 on the curved aluminum plate, which facilitates the control of the pressure plate 37 to apply appropriate pressure to the curved aluminum plate, avoiding excessive pressure that could cause deformation of the aluminum plate. The guide ring 36 plays a guiding role, moving up and down outside the piston rod 35 to prevent the pressure plate 37 from bending, thereby ensuring that the tension and pressure sensor 41 can normally detect the pressure from the pressure plate 37.

[0054] The operating method of the aluminum plate curved surface adaptive clamping dynamic compensation welding device is as follows:

[0055] S1. Place two identical curved aluminum plates on top of the support plate 15 with them close together. Then, move the top rod 18 up to lift the elastic plate 9, making the elastic plate 9 arch. Then, the hydraulic cylinder 4 drives the moving plate 5 to move inward, so that the elastic plate 9 is kept in an arched state, and the tops of multiple support plates 15 contact the inner surface of the curved aluminum plate, thereby supporting the inner surface of the curved aluminum plate.

[0056] S2. When the elastic plate 9 arches up, the top of the curved aluminum plate comes into contact with the thermally conductive silicone sheet 33. Then, the cylinder 34 drives the pressure plate 37 to move down and press the top of the curved aluminum plate. The tension and pressure sensor 41 detects the pressure of the pressure plate 37 on the upper surface of the curved aluminum plate to ensure that the pressure of the pressure plate 37 on the curved aluminum plate is at an appropriate value.

[0057] S3. Subsequently, the laser welding head 26 moves left and right to weld the joint of the two curved aluminum plates. At the same time, the laser rangefinder 27 detects its distance from the curved aluminum plate, so that the laser welding head 26 can weld the curved aluminum plate at a suitable distance. When the laser welding head 26 welds the curved aluminum plate, the heat of the curved aluminum plate is transferred to the thermally conductive silicone pad 33, and the thermally conductive silicone pad 33 transfers the heat to the heat sink 32 for heat dissipation.

[0058] S3 also includes the following steps:

[0059] S31, the infrared thermometer 39 detects the local temperature on the surface of the curved aluminum plate. When the local temperature rises to the set value, the cylinder 34 in that area drives the pressure plate 37 to move upward, so as to avoid the pressure plate 37 pressing the high temperature curved aluminum plate and causing deformation of the curved aluminum plate.

[0060] Working Principle: Before using the aluminum plate curved surface adaptive pressing dynamic compensation welding device, check whether there are any problems affecting its use. Place two identical curved aluminum plates on top of the support plate 15 with them tightly attached one to the other. Then, move the top rod 18 upward to lift the elastic plate 9, causing it to arch. Next, the hydraulic cylinder 4 drives the moving plate 5 to move inward, keeping the elastic plate 9 in an arched state. This ensures that the tops of the multiple support plates 15 contact the inner surface of the curved aluminum plate, thus supporting the inner surface. When the elastic plate 9 arches, the top of the curved aluminum plate contacts the thermally conductive silicone sheet 33. Then, the cylinder 34 moves the pressure plate 37 downward to press the top of the curved aluminum plate, applying tension and pressure. Sensor 41 detects the pressure of pressure plate 37 on the upper surface of the curved aluminum plate, ensuring that the pressure of pressure plate 37 on the curved aluminum plate is at an appropriate value. Then, the laser welding head 26 moves left and right to weld the joint of the two curved aluminum plates. At the same time, the laser rangefinder 27 detects its distance from the curved aluminum plate, so that the laser welding head 26 can weld the curved aluminum plate at an appropriate distance. When the laser welding head 26 welds the curved aluminum plate, the heat of the curved aluminum plate is transferred to the thermally conductive silicone pad 33. The thermally conductive silicone pad 33 transfers the heat to the heat sink 32 for heat dissipation. The infrared thermometer 39 detects the local temperature on the surface of the curved aluminum plate. When the local temperature rises to the set value, the cylinder 34 in that area drives pressure plate 37 to move upward, so as to avoid the pressure plate 37 pressing the high-temperature curved aluminum plate and causing deformation of the curved aluminum plate.

9. The method of using the adaptive pressing dynamic compensation welding device for curved aluminum plates according to claim 8, characterized in that: The method of using the aluminum plate curved surface adaptive pressing dynamic compensation welding device is as follows: S1. Place two identical curved aluminum plates on top of the support plate (15) in a close-fitting manner, then make the elastic plate (9) arch up. Then, the hydraulic cylinder (4) drives the moving plate (5) to move inward, so that the elastic plate (9) is kept in an arched state, and the tops of multiple support plates (15) contact the inner surface of the curved aluminum plate, thereby supporting the inner surface of the curved aluminum plate. S2. When the elastic plate (9) arches up, the top of the curved aluminum plate comes into contact with the thermally conductive silicone sheet (33). Then the cylinder (34) drives the pressure plate (37) to move down to press the top of the curved aluminum plate. The tension and pressure sensor (41) detects the pressure of the pressure plate (37) on the upper surface of the curved aluminum plate to ensure that the pressure of the pressure plate (37) on the curved aluminum plate is at an appropriate value. S3. Then the laser welding head (26) moves left and right to weld the joint of the two curved aluminum plates. At the same time, the laser rangefinder (27) detects the distance between itself and the curved aluminum plate, so that the laser welding head (26) can weld the curved aluminum plate at a suitable distance. When the laser welding head (26) welds the curved aluminum plate, the heat of the curved aluminum plate is transferred to the thermally conductive silicone pad (33), and the thermally conductive silicone pad (33) transfers the heat to the heat sink (32) for heat dissipation.

The infrared thermometer (39) detects the local temperature of the curved aluminum plate surface. When the local temperature rises to the set value, the cylinder (34) of the local area drives the pressure plate (37) to move upward, so as to avoid the pressure plate (37) pressing the high temperature curved aluminum plate and causing the curved aluminum plate to deform.
