Abstract

The utility model relates to a novel AC welder, comprising an iron core, a coil, a separation switch for coarse adjustment, a wiring terminal for current input, a wiring terminal for welding current output and a machine shell. The utility model is characterized in that a primary winding coil is divided into two parts which are respectively fixed and assembled on two core posts of the iron core. A tap of the primary winding coil is connected with the separation switch for coarse adjustment. A secondary winding coil is also divided into two parts. One part is fixed and assembled on one core post of the iron core. The other part is movably assembled on the other core post, and connected with a turn knob for fine adjustment through a connecting piece. The novel AC welder can enable current to be continuously controlled without currentless zones. Simultaneously, the utility model has the advantages of small size, light weight, simple structure, electric energy saving and low cost.

Description

Novel A.C. welder

The utility model belongs to a kind of electric welding machine, particularly a kind of novel A.C. welder.

That the tapped A.C. welder of BX6 type that provides in the market has is energy-conservation, volume is little, in light weight, advantage such as price is lower, but because this kind electric welding machine is to adjust welding current by the tap of adjusting primary coil, therefore exist the dead zone of electric current between each grade of welding current, electric current can't be realized continuous adjusting, particularly the Current Regulation scope is bigger, and the dead zone between adjacent two grades is also just big more.With the BX6-200A electric welding machine is example: Current Regulation is divided into seven shelves from 60A-200A, and the electric current dead zone between every grade is 20A, like this, some is needed the workpiece of accurate welding, obviously is inefficient.Also has a kind of BX3 type moving-coil type A.C. welder, though electric current can be regulated from low to high continuously, but textural, must iron core column do very high very long, strengthened the consumption of silicon steel sheet, it is very heavy that volume becomes, the screw rod of Tiao Jieing is long simultaneously, can not cross and access longways outside the casing, screw rod must be installed in the iron core column like this, thereby cause the technology more complicated.

The purpose of this utility model provides a kind of novel A.C. welder, and electric current is regulated continuously, the no current dead zone, and volume is little, in light weight, simple in structure simultaneously, saves energy, cost is lower.

The purpose of this utility model is achieved in that it comprises iron core, coil, coarse adjustment switch, electric current lead-in clamp, welding current output wiring terminal and casing separately, its technical scheme main points are: primary winding coils is divided into two parts, fixedly be assembled in respectively on two stem stems of iron core, the primary winding coils tap is connected with coarse adjustment parted hair switch; The secondary winding coil also is divided into two parts, and a part fixedly is assembled on the stem stem of iron core, and another part activity is assembled on another stem stem of iron core, and connects vernier knob by connector.Operation principle: can carry out tapped electric current coarse adjustment by coarse adjustment parted hair switch in use, change the position of movable secondary winding coil simultaneously by vernier knob, change its leakage reactance, carry out the thin tuning of electric current.

The utility model has the advantages that: electric current is regulated continuously, the no current dead zone, simultaneously little, in light weight, simple in structure, the saves energy of volume, cost are low.

Below in conjunction with accompanying drawing the utility model embodiment is described further.

Fig. 1 is the utility model embodiment 1 structural representation.

Fig. 2 is that vernier knob part mounting structure A is to schematic diagram.

Fig. 3 is the utility model embodiment 1 circuit theory schematic diagram.

Fig. 4 is the utility model embodiment 2 structural representations.

Fig. 5 is the utility model embodiment 2 circuit theory schematic diagrames.

See Fig. 1-3, embodiment 1 is " mouth " font double core leg structure: by the fixed angles steel bracket 7 hollow twin-core column iron core 11 that is fixedly connected, two

parts

12,14 of primary winding coils are fixed on two stem stems assembling iron core respectively casing 8 in; The secondary winding coil also is divided into two

parts

10,15, and wherein a coil part 15 fixedly is assembled on the stem stem, and another part is wrapped on the

bakelite framework

17, and 17 activities of bakelite framework are assembled on another stem stem, can carry out short distance on stem stem and move.Bakelite framework 17 is fixedly connected with connector, connector is a coupling bar 9 and gusset piece 18, coupling bar 9 passes angle bar frame 7, welded nut 19 on the gusset piece 18, the screw 5 of band knob 4 is screwedly mounted on the nut 19, the end of screw 5 is axially fixed on the support plate 2O, and support plate 20 is fixed together with angle bar frame 7.Primary winding coils is connected on the input ac power 13, and the tap 16 of primary winding coils connects coarse adjustment switch 3 separately, and coarse adjustment has coarse adjustment knob 2 on the switch 3 separately.Secondary winding coil two parts are connected mutually, are connected source of welding current output wiring terminal 1.

See Fig. 4,5, embodiment 2 is

Font three iron core column structures: its

primary winding coils

12,14 and

secondary winding coil

10,15 are assembled in respectively on two side columns of three stem stems.At power input link position switch 21, use three-phase alternating-current supply and 220V power supply respectively by switching.Other structure is with embodiment 1.
