Detailed Implementation

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0023] This invention provides a laser-arc hybrid welding device for thick-walled components in shipyards, see details below. Figure 1 The difference between this and existing technologies lies in the fact that the welding device includes dual welding robots, a dual-robot lifting beam system that works in conjunction with the dual welding robots, two sets of longitudinal moving column systems, and two sets of 10,000-watt laser arc composite welding systems. This allows the dual welding robots to move laterally on the same beam simultaneously and perform laser arc composite welding. The dual-robot lifting beam system includes a dual-robot beam with two movable horizontal sliding tables. The horizontal sliding tables are equipped with horizontal servo motors and drive gears. Laser distance sensors are installed on the inner sides of the two horizontal sliding tables to ensure a safe working distance between the dual welding robots.

[0024] The longitudinal moving column system includes a column and a vertical servo motor located at the top of the column. The vertical servo motor is connected to a vertical ball screw located in the middle of the column via a flexible coupling. The horizontal sliding table has crossbeam transfer slides at both ends that cooperate with the vertical ball screw. The column has a set of vertical linear guides that cooperate with the two sides of the crossbeam transfer slides. The vertical servo motor drives the vertical ball screw to rotate, causing the crossbeam transfer slides to move up and down along the vertical linear guides, thereby driving the dual robot crossbeam system to move up and down. The bottom of the column has a longitudinal platform base frame, which has a drive system. The column and the longitudinal platform base frame form a longitudinal sliding connection through the column transfer slides.

[0025] In use, the dual-robot lifting beam system is mainly used to carry the laser arc welding power supply and two welding robots for overall lifting and lowering. It also provides lateral drive for the welding robots and uses sensors to ensure that the robots automatically maintain a safe distance during horizontal movement, preventing interference. The longitudinal moving column system mainly includes vertical columns, vertical linear guides, longitudinal drive motors, vertical ball screws, motion support nuts, and a platform base frame. It primarily guides and supports the overall lifting beam. The servo motors at the top of the two columns move synchronously, ensuring reliable lifting and lowering of the beam carrying the robots and the laser arc welding power supply. Simultaneously, the servo motors at the bottom of the columns drive horizontal longitudinal movement on the longitudinal platform base frame. The 10,000-watt laser arc composite welding system mainly includes a laser power supply module, an arc welding power supply module, a cooling system module, and a robot module. It primarily uses a laser power supply with a maximum output power of 20,000 watts and an arc welding power supply with a maximum output current of 500A to weld T-shaped, H-shaped, and channel-shaped steel components with a maximum wall thickness of 32mm. This saves significant time and costs and improves welding production efficiency. Meanwhile, the stability of robotic welding ensures welding quality, and the appearance of the weld, non-destructive testing, and destructive testing all meet the relevant requirements of CCS "Materials and Welding Specifications".

[0026] Example 1 In this embodiment, the welding device includes dual welding robots, a dual-robot lifting beam system that works in conjunction with the dual welding robots, two sets of longitudinally moving column systems, and two sets of 10,000-watt laser-arc composite welding systems, enabling the dual welding robots to move laterally on the same beam simultaneously and perform laser-arc composite welding. The dual-robot lifting beam system includes a dual-robot beam with two movable horizontal sliding tables. The horizontal sliding tables are equipped with horizontal servo motors and drive gears, and laser distance sensors are installed on the inner sides of the two horizontal sliding tables to ensure a safe working distance between the dual welding robots.

[0027] The longitudinal moving column system includes a column and a vertical servo motor located at the top of the column. The vertical servo motor is connected to a vertical ball screw located in the middle of the column via a flexible coupling. The horizontal sliding table has crossbeam transfer slides at both ends that cooperate with the vertical ball screw. The column has a set of vertical linear guides that cooperate with the two sides of the crossbeam transfer slides. The vertical servo motor drives the vertical ball screw to rotate, causing the crossbeam transfer slides to move up and down along the vertical linear guides, thereby driving the dual robot crossbeam system to move up and down. The bottom of the column has a longitudinal platform base frame, which has a drive system. The column and the longitudinal platform base frame form a longitudinal sliding connection through the column transfer slides.

[0028] Each horizontal transverse slide is equipped with a welding robot. The horizontal transverse slide is slidably engaged with the crossbeam of the two robots through the transverse linear guide 23 and the crossbeam rack. Each horizontal transverse slide is equipped with a transverse zero-position sensor and a transverse slide limit sensor, so that the two welding robots are initially positioned at the zero positions at both ends of the crossbeam of the two robots.

[0029] The transverse linear guide rail 23 cooperates with the horizontal transverse slide block 16, which is located on the horizontal transverse slide block, to form a slidable connection. See details. Figure 6 The horizontal linear guide rail is I-shaped, and the horizontal sliding slide connecting slider 16 is provided with a groove that mates with the horizontal linear guide rail. There is a gap between the bottom of the groove and the horizontal linear guide rail, with a gap value of 0.5-1.5mm, which makes the sliding smoother.

[0030] Furthermore, the horizontal sliding slide is equipped with a motor base rotating hinge, a rotating motor base, and a guide seat. The servo motor is mounted on the rotating motor base via a reducer base. One end of the rotating motor base is connected to the motor base rotating hinge via a motor base rotating pin, and the other end is elastically fixed to the guide seat via an adjusting screw and a gear clearance adjusting spring 28. The adjusting screw is located at the bottom of the gear clearance adjusting spring. See details. Figure 5 By adjusting the tightness of the long screw 29, the gap between the drive gear and the crossbeam rack is adjusted, enabling the welding robot to perform high-precision lateral movements.

[0031] In the aforementioned longitudinal moving column system, the top and bottom of the column are respectively provided with a top motor seat and a bottom bearing seat. The vertical servo motor is connected to the column through the top motor seat. The upper and lower ends of the vertical ball screw are fixedly connected to the top motor seat and the bottom bearing shaft of the column through upper and lower double-row ball bearings, respectively. The crossbeam transfer slide is provided with a vertical motion support nut, a vertical zero-position sensor, a vertical limit sensor, and a screw nut that cooperates with the vertical ball screw.

[0032] Furthermore, the longitudinal platform base is equipped with a longitudinal linear guide rail and a longitudinal rack that cooperates with the longitudinal linear guide rail. The bottom of the column is equipped with a longitudinal motor rotating base, on which a longitudinal servo motor and a drive gear connected to the longitudinal servo motor are installed. The drive gear drives the longitudinal rack, so that the column can move longitudinally horizontally along the longitudinal linear guide rail. The column transfer slide is equipped with a longitudinal zero-position sensor and a longitudinal limit sensor.

[0033] The aforementioned 10,000-watt laser-arc hybrid welding system mainly includes a laser power supply, an arc welding power supply, a cooling system, and a robot module that works in conjunction with a dual-welding robot. The laser power supply has a rated power of 18,000 watts and a maximum output power of 20,000 watts. The arc welding power supply has a maximum welding current of 500A. The cooling system uses a water circulation method for cooling, enabling the welding of T-shaped, H-shaped, and channel-shaped steel components with a maximum wall thickness of 32mm.

[0034] Example 2 In this embodiment, the dual robot beam 1 is first raised and lowered to a specified height. The laser and welding power supply is installed on the power support 48. The power cable and related data cable are connected to the two horizontal sliding tables 14 of the robot through the dual drag chain mechanism 31. At the same time, two precision linear guide rails 23 are set on the side of the beam, and a rack 22 is installed on the top of the beam to drive and guide the horizontal sliding tables 14 of the two robots. Finally, left and right end limiter mounting seats 12 are set at the extreme positions at both ends of the beam, and left and right end limiters 13 are installed respectively to ensure the safe operation of the two robot systems.

[0035] The upper part of the transverse slide 14 is equipped with a motor base rotating hinge 2. The servo motor 5 is mounted on the rotary motor base 4 via a reducer base 8. One end of the rotary motor base 4 is connected to the motor base rotating hinge 2 via a motor base rotating pin 3, and the other end is elastically fixed to the guide seat 11 via an adjusting long screw 29 and a gear clearance adjusting spring 28. By adjusting the tension of the long screw 29, the clearance between the drive gear 6 and the rack 22 on the servo motor shaft is adjusted, thereby achieving high-precision lateral movement of the robot. Laser rangefinders 17 are installed on the inner sides of the two transverse slides 14 to ensure that the two robots always maintain a safe distance and do not interfere with each other. In addition, transverse slides 14 are equipped with a lateral zero-position sensor 52 and a transverse slide limit sensor 15 to ensure that the two robots are at the zero position at both ends of the crossbeam in the initial state of the equipment and to ensure the safe operation of the entire system.

[0036] A vertical servo motor 18 is installed at the top of the longitudinal moving column 27, connected to the column via a motor mount 19 at the top of the column. Simultaneously, a vertical ball screw 46 is connected via a flexible coupling 20. The vertical ball screw 46 is fixed to the motor mount 19 at the top of the column and the bearing mount 26 at the bottom of the column via double-row ball bearings 21 / 25, respectively. A vertical movement support nut 47 is fixed to the crossbeam transition slide 32. The two sets of vertical servo motors 18 synchronously drive the vertical ball screws 46 of the two columns 27 to rotate, thereby driving the transition slides 32 installed at both ends of the crossbeam, along with the copper nuts, to move up and down along the vertical linear guide rail 45, thus driving the entire dual-robot crossbeam 1 to move up and down. Furthermore, the crossbeam transition slide 32 is equipped with a vertical zero-position sensor 35 and a vertical limit sensor 44 to ensure that the dual-robot crossbeam remains at the zero position of the column in the initial state of the equipment and to ensure the safe operation of the entire system.

[0037] The longitudinally moving columns 27 are mounted on the longitudinal platform base 37 via column transfer slides 42. The platform base 37 is equipped with longitudinal linear guides 54 and longitudinal racks 38. A longitudinal servo motor 40 on the longitudinal motor rotating base 36 at the bottom of the column drives the gear 39 and rack 38 transmission mechanism, thereby causing the two sets of columns 27 to move synchronously in the horizontal longitudinal direction. Furthermore, the column transfer slides 42 are equipped with longitudinal zero-position sensors 53 and longitudinal limit sensors 43 to ensure that the dual robot beams remain at the zero position of the columns in the initial state of the equipment and to guarantee the safe operation of the entire system.

[0038] The 10,000-watt laser-arc hybrid welding system features a laser power supply (49) with a rated power of 18,000 watts and a maximum output power of 20,000 watts. The arc welding power supply is a TPS500i CMT with a maximum welding current of 500A. The welding machine works in conjunction with the laser system and is cooled by water circulation. It can weld T-shaped, H-shaped, and channel-shaped steel components with a maximum wall thickness of 32mm. The system is equipped with two 10,000-watt laser arc welding power supply systems, each carried by a robot (30). It is compatible with butt welds and fillet welds and uses a laser tracking system to ensure welding quality.

[0039] This 10,000-watt laser-arc hybrid welding method and device for welding thick-walled components in shipyards has the following characteristics: it is suitable for double-sided fillet welding of T-shaped, H-shaped, and channel-shaped steel components with a maximum wall thickness of 32mm, and the entire welding process does not require manual intervention, saving a lot of labor costs; the weld quality has good uniformity, the welding quality is stable and reliable, the welding efficiency is effectively improved, and the on-site working environment can be greatly improved, significantly increasing the production efficiency and automation level of welding thick-walled components in domestic shipyards.
