Abstract

The utility model relates to a fastening device for a transformer of an electric welding machine. The fastening device is used in the electric welding machine and comprises a first fastener, a second fastener, a first fastening sheet and a second fastening sheet. The first fastener is fixed with the first fastening sheet, and the second fastener is fixed with the second fastening sheet. A bayonet is fixed on the first fastening sheet, a first clamping tooth is arranged in the bayonet, and a second clamping tooth is arranged on the second fastening sheet. The fastening device for the transformer of the electric welding machine has a good fastening effect on a silicon-steel sheet, ensures performance of the transformer, and protects the transformer. In addition, a gap is hard to produce.

Description

A kind of fastener for electric welder transformer

Technical field

The utility model relates to a kind of fastener for electric welder transformer, 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 provide a kind of reasonable in design, silicon steel sheet the fastening effective fastener that is used for electric welder transformer.

The technical scheme in the invention for solving the above technical problem is: a kind of fastener for electric welder transformer is characterized in that: comprise a securing member, No. two securing members, a connecting plate, No. two connecting plates; A securing member and a connecting plate are fixed, and No. two securing members and No. two connecting plates are fixed; Be fixed with bayonet socket at a connecting plate, have latch in the bayonet socket No. one; Have latch No. two at No. two connecting plates.Connecting plate and No. two connecting plates can being fixed by bayonet socket and No. two latches; a securing member and No. two securing members are clipped in the middle iron core; the iron core centre position had larger clamping force; silicon steel sheet is fastening effective; gap utmost point difficult labour is given birth to; guarantee the performance of transformer, protected transformer.

The utility model has four one number service holes at a described securing member.During installation, four through holes on four jiaos of four one number service holes and silicon steel sheet are corresponding, and the fastening bolt of transformer 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.During installation, four through holes on four jiaos of four No. two through holes and silicon steel sheet are corresponding, and the fastening bolt of transformer 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: fastening effective to silicon steel sheet, utmost point difficult labour in gap is given birth to, and has guaranteed the performance of transformer, has protected transformer.
