Description
Technical field
The utility model relates to a kind of transformer of electric welding machine, is used for electric welding machine.
Background technology
The transformer of electric welding machine comprises iron core and winding, and iron core forms by many groups silicon steel sheet is superimposed, and core center is formed for holding the chamber of winding, and winding is arranged in this chamber.Have four through holes on four jiaos of silicon steel sheet, in four through holes fastening bolt is installed, it is fastening that fastening bolt and fastening nut cooperate silicon steel sheet, this fixed form be four jiaos fastening, fastening effective in four angles of iron core, but fastening effect is bad in the centre position, can produce the gap between the silicon steel sheet, has so not only affected the performance of transformer, and because the operational environment of electric welding machine is poor, foreign material are more, if foreign material enter the gap between the silicon steel sheet, will damage transformer when serious.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and transformer that the fastening effective electric welding machine of a kind of reasonable in design, silicon steel sheet is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of transformer of electric welding machine, comprise iron core and winding, and iron core forms by many groups silicon steel sheet is superimposed, and core center is formed for holding the chamber of winding; Have four through holes on four jiaos of silicon steel sheet, in four through holes fastening bolt is installed, fastening bolt cooperates silicon steel sheet fastening with fastening nut; It is characterized in that: also comprise a securing member and No. two securing members, a securing member and No. two securing members are oppositely arranged, and iron core clamp is between securing member and No. two securing members; Be fixed with connecting plate No. one at a securing member, be fixed with connecting plate No. two at No. two securing members, a connecting plate and No. two connecting plates are screwed.By fixing of a connecting plate and No. two connecting plates, a securing member and No. two securing members are clipped in the middle iron core, and the iron core centre position is also had larger clamping force; silicon steel sheet is fastening effective; gap utmost point difficult labour is given birth to, and has guaranteed the performance of transformer, has protected transformer.
A securing member described in the utility model is shaped as frame.Can wear winding in the middle of such securing member, No. one much more as far as possible securing member must contact with silicon steel sheet, has increased the clamping effect.
No. two securing members described in the utility model are shaped as frame.Can wear winding in the middle of such No. two securing members, No. two much more as far as possible securing member must contact with silicon steel sheet, has increased the clamping effect.
The utility model has four one number service holes at a described securing member, and four through holes on four jiaos of four one number service holes and silicon steel sheet are corresponding.Fastening bolt passes the one number service hole, and securing member and silicon steel sheet is fastening.
The utility model has four No. two through holes at described No. two securing members, and four through holes on four jiaos of four No. two through holes and silicon steel sheet are corresponding.Fastening bolt passes through hole No. two, and No. two securing members and silicon steel sheet is fastening.
The utility model compared with prior art has following advantage and effect: silicon steel sheet is fastening effective, and utmost point difficult labour in gap is given birth to, and has guaranteed the performance of transformer, has protected transformer.
