Abstract
The utility model discloses a synchronous electric generator with a DC arc welding machine, which is integrated with two functions of the direct current arc welding and the AC electric generation. The AC generator adopts the rotary armature structure; the exciting portion of the AC generator is arranged on a stator and can commonly have the iron core of the main pole and a set of excitation windings; the poles are mutually connected in serially; the stator is simultaneously provided with a set of reversing pole windings; the upper layer in the rotor slot is embedded with a set of DC armature windings which are connected with a commutator; the lower layer is embedded with a set of AC armature windings which are connected to a current conducting rod; a wire connecting box is introduced through a sliding ring and an electric brush, and the commutator and the sliding ring are manufactured to be integration.
Description
The utility model relates to a kind of generator, particularly a kind of direct-current arc welding AC synchronous electricity generation two-purpose machine.
At present, of home make generator is used for single goal more, perhaps use simple DC arc welder to be used for welding, perhaps simple synchronous generator provides single-phase alternating current, especially two kinds of functions are used direct-current arc welding and the alternative electric generation dual-purpose motor with the functional part of one, still belong to blank at present.
The purpose of this utility model is to provide that a kind of volume is little, cost is low, easy to use, and can be applicable to the direct current welding simultaneously and the direct-current arc welding AC synchronous electricity generation two-purpose machine of single phase alternating current power supply is provided.
To achieve these goals, the utility model adopts following technical scheme: a kind of direct-current arc welding AC synchronous electricity generation two-purpose machine, comprise stator, rotor and output mechanism, it is characterized in that, alternating current generator adopts the pivot-rotatable type structure, its excitatory part be located on the stator and with the shared cover main pole iron core of DC arc welder and the cover excitation winding on the main pole iron core, interpolar is connected mutually, the commutation part of stator is made up of around the commutation winding on the commutating pole iron core a cover commutating pole iron core and a cover, interpolar is connected mutually, the shared rotor core of DC arc welder and alternating current generator, this iron core is repeatedly pressed by silicon steel sheet and is formed, embed a cover DC armature winding in rotor, lower floor embeds a cover and exchanges armature winding, and the DC armature winding links to each other with commutator, exchange armature winding and be connected to conducting rod, introduce terminal box by slip ring and brush, commutator and slip ring are made one, and conducting rod passes through from commutator inside.
Compared with the prior art the utility model has conspicuous advantage, two kinds of functions of direct-current arc welding and alternative electric generation are used the functional part with one, thereby reduced volume reduces cost, the convenient use can be applicable to the direct current welding simultaneously and single phase alternating current power supply is provided.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model rotor structure schematic diagram;
Fig. 3 is the utility model stator structure schematic diagram;
Fig. 4 is the utility model commutator and slip ring structural representation;
Fig. 5 is the utility model circuit theory diagrams.
To shown in Figure 5, alternating current generator adopts the pivot-rotatable type structure as Fig. 1, its excitatory part be placed on the stator 1 and with shared four main pole iron cores 11 of DC arc welder and the four groups excitation winding 12 on the main frame iron core respectively, interpolar is connected mutually.The commutation of stator part by two commutation iron cores 13 and two groups respectively the commutation winding 14 on the commutating pole iron core form, interpolar is connected mutually.The shared same rotor core 2 of DC arc welder and alternating current generator, this iron core are repeatedly pressed by silicon steel sheet and are formed, and the upper strata embeds a cover DC armature winding 22 in rotor 21, and lower floor embeds a cover and exchanges armature winding 23.The DC armature winding links to each other with commutator 3, exchanges armature winding and is connected to conducting rod 4, introduces terminal box 7 by slip ring 5 and brush 6, and commutator and slip ring are made one, and conducting rod passes through from commutator inside.
When prime mover drove main axis rotation, according to electromagnetic induction principle, the remanent magnetism in the iron core was set up exciting voltage and is produced exciting curent by energizing loop in excitation winding, thereby exciting curent has been strengthened the higher exciting voltage of excitatory magnetic field boundary generation again.So continue, finally on stator, form gradually and stablize the magnetic field boundary.Under the effect of this magnetic field boundary, the DC armature winding with exchange armature winding and all produce output voltage, the DC armature winding is connected to commutator, and introduces terminal box by brush, output DC stream, the big I of welding current changes by the resistance that adjusting is serially connected with the rheostat R in the energized circuit.AC Windings is connected to the conducting rod of slip ring and introduces U, the V terminal of terminal box by slip ring and brush, and single-phase alternating current is provided.
