Technical Field
[0001] The utility model relates to the technical field of welding machine transformers, in particular to a protection structure of a welding machine transformer. Background Art
[0002] A welding machine is an electrical appliance that provides a power supply with certain characteristics for welding. Its main component is a step-down transformer. By igniting the arc, the welding rod is melted into the gap of the workpiece in the high temperature of the arc, thereby achieving the welding effect. Since the transformer in the welding machine needs to be frequently inspected and maintained, most transformers are fixed inside the welding machine housing by bolts and other structures. However, the transformer will emit large vibrations during operation. Bolts and other mounting structures will form a whole between the transformer and the welding machine housing, which will cause the vibration emitted by the transformer to resonate with the housing of the welding machine, amplify the vibration emitted by the transformer, and react to the transformer, which can easily cause the internal coil of the transformer to fall off and parts to be damaged, and the shock absorption protection effect of the transformer is poor.
[0003] Chinese patent announcement number CN218456018U discloses a protective structure for a welding machine transformer, in which the transformer body is arranged between two top plates. When the transformer vibrates, the two top plates can be driven to move up and down. The top plates can drive two movable blocks to slide on the surface of the round rod through the transmission rod and squeeze the spring to deform it. The spring can greatly offset the vibration generated by the transformer body and return to a normal state after being damped by a viscous damper, thereby avoiding resonance between the transformer body and the welding machine housing, thereby improving the protective effect of the transformer body.
[0004] Since the protective structure of the welding machine transformer does not set a limiting structure for the transformer body at the top of the top plate, the transformer body will be displaced when vibration occurs, and it is impossible to ensure that the transformer body is stable in the middle of the top of the top plate.
