Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to a welding tool for a generator set base shell. Background Art

[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, control system, silencer system, shock absorption system, and exhaust system. It is driven by a turbine, steam turbine, 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 shell and the base, the shell is difficult to clamp due to its arc shape, and unstable clamping can easily lead to welding deviation, resulting in unstable welding fixation of the shell and the base, affecting subsequent work. In addition, when welding, the straight line between the shell and the base needs to be polished and derusted in advance before welding due to the long straight line distance, and the welding slag needs to be cleaned after welding. If pretreatment before processing and cleaning after processing are not done, the welding effect will be affected, resulting in unstable welding. When welding, the arc between the shell and the base needs to be welded because the weld is arc-shaped, which requires a high level of welding technology for the workers. Moreover, due to the large size of the shell, other height lifts are required to assist the workers in moving for welding, which is extremely inconvenient and the welding quality is difficult to guarantee.

When working, the user can quickly position the base 130 on the conveyor belt 110 through the positioning block 111, and then place the shell 140 on the base 130. Then, the conveyor belt 110 is started, and the conveyor belt 110 drives the base 130 and the shell 140 to move. When the conveyor belt 110 drives the shell 140 and the base 130 to move to the bottom clamping plate 220, the first slide bar 230, the second slide bar 250, the third slide bar 260, the fourth slide bar 520 and the connecting rod 120 cooperate to realize the clamping function of the arc clamping plate and the bottom clamping plate 220, and the rust removal liquid flows into the second slide bar 250, and the rust removal liquid is sprayed out through the rust removal liquid spray port 256. At the same time, the rust removal grinding The wheel 253 and the welding slag grinding wheel 570 are moved to a suitable position for easy work. The rust removal grinding wheel 253 completes the rust removal work. Then, when the conveyor belt 110 moves the shell 140 and the base 130 to the welding assembly 300, the conveyor belt 110 stops working, and the welding assembly 300 starts working. The driving assembly 400 drives the welding head 350 to rotate along the arc guide groove 320 to complete the welding of the arc joint on the front side between the base 130 and the shell 140. Then, the driving assembly 400 stops working, and the conveyor belt 110 drives the shell 140 and the base 130 to continue moving. The welding head 350 continues to work to complete the welding of the straight line joint on the side between the base 130 and the shell 140. Then, the conveyor belt 110 stops working, and the driving assembly 400 starts working. The driving assembly 400 stops working, the conveyor belt 110 moves in the opposite direction, and the welding head 350 continues to work to complete the welding of the linear joint between the base 130 and the shell 140 on the other side. Then, the conveyor belt 110 moves forward to drive the shell 140 and the base 130 to continue to move forward. The cleaning assembly 500 starts working, and the welding slag grinding wheel 570 cleans the welding slag generated by welding. At the same time, the clean water spray port 582 sprays clean water to assist in cleaning. Among them, the generator base shell welding tool of the present invention facilitates clamping the shell 140 and the base 130 through the mutual cooperation of various structures.At the same time, it also ensures the straight-line welding effect between the base 130 and the shell 140 and the arc-fitting welding effect between the base 130 and the shell 140. In addition, the grinding and rust removal before welding and the cleaning of welding slag after welding can be completed simultaneously, further ensuring the welding effect.
