Technical Field
[0001] This invention relates to the field of automatic arc welding technology for diesel generator sets, specifically a welding device for the base of a diesel generator set. Background Technology
[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It consists of a power system, a control system, a noise reduction system, a vibration damping system, and an exhaust system. It is driven by a water turbine, a steam turbine, a diesel engine, or other power machinery. It converts the energy generated by water flow, air flow, fuel combustion, or nuclear fission into mechanical energy, which is then transferred to the generator. The generator then converts the mechanical energy into electrical energy, which is then output to electrical equipment for use. When welding the base of a diesel generator set, arc welding is used. Arc welding is also the most widely used welding method in industrial production.
[0003] A search revealed Chinese Patent Publication No. CN117900677A, which discloses a welding device for a diesel generator set base. The device includes a base, a welding table fixedly connected to the upper end of the base, slide rails fixedly connected to both sides of the upper surface of the welding table, a frame slidably connected to the slide rails, a slider slidably connected to the upper end of the frame, electric push rods fixedly connected to both sides of the lower end of the slider, a mounting base fixedly connected to the piston end of the electric push rod, a welding torch mounted on the lower end of the mounting base, and a scraping and falling welding slag separation and collection mechanism at the upper end of the base. This technology enables the use of electromagnets to adsorb and collect iron from the knocked-off welding slag, achieving resource recovery. By clamping and pressing, the diesel generator set base can be positioned, thus ensuring its stability during the welding process.
[0004] A search revealed Chinese Patent Publication No. CN119159316B, which discloses an auxiliary clamping device for welding diesel generator set bases. This device relates to the field of clamping and positioning fixtures, and includes a clamping and positioning platform. The platform is a horizontally positioned square platform, and is equipped with a conveying and transferring component, a flipping upper clamping component, a sliding side clamping component, a steering and positioning component, and a rolling adjustment component. This solution addresses the problems of traditional clamping fixtures used for auxiliary clamping in welding generator set bases, such as limited clamping methods, poor adaptability and coordination, inconvenience in secondary adjustments of components during welding, and inconvenience in double-sided welding operations due to limitations imposed by the clamping method.
[0005] In existing diesel generator sets, the fuel tank needs to be installed inside the base during automatic arc welding assembly. However, the base steel structure needs to be positioned and adjusted before welding and assembly. The heavy steel structure makes it inconvenient to adjust the position quickly, and the fuel tank cannot be guaranteed to be properly installed in the base frame after welding. Furthermore, the movement and adjustment of the diesel engine and generator of the diesel generator set will affect the assembly welding and prevent the quick connection between the base and the whole. Therefore, a welding device for diesel generator set bases is proposed to solve the above problems. Summary of the Invention

[0019] 4. The welding device for the base of the diesel generator set uses a moving component and a grab plate to move the assembled components, so that the base can be directly assembled during welding and assembly, reducing the problem that the frame cannot be combined with the fuel tank and diesel engine after welding.
