Description

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy into electrical energy. It is composed of a power system, a control system, a silencer system, a shock absorption system, and an exhaust system. It is driven by a 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 and transmits it to the generator, which then converts it into electrical energy and outputs it to electrical equipment for use. The generator set will generate huge vibrations during operation, and the casing and base need to be welded and fixed, otherwise it will cause damage to the equipment.

[0003] When welding the base and the motor casing, the existing equipment has omissions in the corner welding, and different angles need to be adjusted when clamping, which is time-consuming and labor-intensive. Manual welding requires being closer to the welding point when welding the angles and corners, which can easily cause burns to the staff.

The dripping cleaning agent slides through the arc baffle 718 and is recovered in the recovery box 719. When the first T-shaped limit block 712 follows the movement of the material tube 79, the slide plate 713 links the grinding wheel 715 to fit the linear weld. The second motor 714 is started to make the grinding wheel 715 stained with the acid cleaning agent to grind the weld. When the grinding wheel 715 fits the weld, the slide plate 713 slides into the first T-shaped limit block 712 and presses the second spring 720 to adapt to bases or shells of different sizes and fit tightly. After the grinding is completed, the conveyor belt 2 is started to continue to push the base body 13 and the shell body 14.Start the second electric telescopic rod 19 to align the spray head 18 with the weld, start the water pump 16 to output the water in the water tank 15 to the spray head 18 through the water outlet hose 17 to clean the weld.
