Abstract

The utility model relates to a multifunctional electric welding machine which is that a secondary winding of an electric welding transformer is divided into a plurality of groups; besides, the utility model is provided with a wiring plate which is provided with a plurality of wiring terminals; output connecting plates which can make windings connected with each other in parallel or in series are arranged on the wiring terminals. The connection modes of the connecting plates on the wiring terminals can be changed according to the using need. Therefore, the utility model has the functions of alternating current arc weld, direct current arc weld, the start of cars, the charge of accumulators and power sources for riveting spot weld or butt weld or rollerseam weld.

Description

The multifunction electric welding machine

Affiliated technical field:

The utility model relates to electric welding machine, is a kind of multifunction electric welding machine.

Background technology:

At present the output current of the electric welding machine that uses and voltage be not suitable for for other welding (as butt welding. riveting spot welding etc.) power supply of use, as " introducing in welder's handbook " manual welding and cutting " 45-47 page or leaf.

Summary of the invention:

In order to make the electric welding machine a tractor serves several purposes.The utility model provides the manufacture method of one kind of multiple purposes electric welding machines.The purposes of this welding machine is: 1. alternating current arc welding 2. for the 3. electronic arc welding of power supply of butt welding and riveting spot welding and roller seam soldering, start automobile, fill storage battery.The novel technical scheme of this use is: the secondary winding of welding transformer divides four groups of (or five groups) coils to press the same number of turns coiling with same lead.And head, the tail sequence number of clear each tapped-winding of volume.(promptly the first tapped-winding head for 1. tail for 2., the head of second tapped-winding for 3. tail for 4., with in proper order downward.) on output wiring board, divide two rows that 10 (or 12) binding posts are installed, and numbering, last row is numbered odd number consecutive number and negative pole, and (promptly 1. 3. 5. 7. _ or 1. 3. 5. 7. 9. _) row down is numbered positive pole and even number consecutive number.(promptly _ 2. 4. 6. 8. or _ 2. 4. 6. 8. 10.) equipped on the binding post can movable intercolumniation conductive connection plates.The head of each sequenced tapped-winding of secondary winding, tail and numbered binding post are checked the number and are joined, (promptly the first tapped-winding head 1. the row's of connecting binding post 1., tail 2. connect down row binding post 2., check the number successively and join) the binding post positive pole _ on connect two diode cathodes, two diode cathodes connect respectively the first tapped-winding head 1. with last grouping coil tail 8. or 10., the binding post negative pole _ on connect need connect centre when using of tapped-winding, binding post just _, negative _ as extremely to go up filtering capacitor etc. is installed.During the mode of connection of several functions following (is example with four groups) (one) alternating current welding arc, secondary four tapped-windings series connection.With connecting plate connect respectively binding post 2. with 3., 4. with 5., 6. with 7..Binding post 1. with 8. on output the time be big electric current, be middle electric current when 6. going up output 1., be little electric current when 4. going up output 1..(2) secondary four tapped-windings series connection during electronic arc welding, two two half-wave (all-wave) rectifying and wave-filterings outputs of diode.Promptly with connecting plate connect respectively binding post 2. with 3., 4. with 5. reach _, 6. with 7..The binding post positive pole _ with negative pole _ on output.During (three) for butt welding, rivet welding, roll welding power supply, the output in parallel of secondary winding four tapped-windings, connecting binding post with connecting plate 7. 5. 3. 1. is an output line, 8. 6. 4. 2. connect is another root output line.(4) start automobile, when filling storage battery, secondary winding first is connected with last two tapped-windings, full-wave rectifier filter is exported.Promptly with connecting plate connect binding post 2.-7.-_.The binding post positive pole _ with negative pole _ output.The electric current fine tuning of this welding machine is elementary.The beneficial effects of the utility model are that a tractor serves several purposes is Duoed several binding posts and connecting plate and secondary winding end to end than single with machine, makes fairly simple.

Description of drawings:

Figure one, is that the welding transformer secondary winding is the wiring instance graph of four tapped-windings and several functions.Elementary winding is the bidirectional thyristor for regulating voltage formula.

Figure two, are that the welding transformer secondary winding is among the wiring instance graph figure of five tapped-windings and several functions: 1. welding transformer 2. welding transformer secondary winding

3. filtering capacitor 4. output wiring boards

5. intercolumniation conductive connection plate 6. binding posts

7. diode 8. elementary voltage regulating mode: figure one two-way controllable silicon figure two tappings

Embodiment: (is example with accompanying drawing one)

As accompanying drawing one, each tapped-winding sequenced of welding transformer (1) secondary winding (2) end to end, the mode of connection that connects the last several functions of numbered binding post (6) of output wiring board (4) of checking the number successively is: during (one) alternating current welding arc, secondary winding (2) four tapped-windings series connection connects the binding post (6) that is numbered 2. with 3., 4. with 5., 6. with 7. respectively with connecting plate (5).Being numbered 1. when 8. going up output at binding post (6) is big electric current, is middle electric current when 6. going up output 1., is little electric current when 4. exporting 1..(2) series connection of secondary winding (2) four tapped-windings is used during the direct current welding arc.Two diodes (7) full-wave rectification, filtering output.With connecting plate (5) connect respectively be numbered 2. with 3.; 4. with 5. reach _; 6. with 7. binding post (6) electric current the first tapped-winding head 1. the 4th tapped-winding tail 8. through diode (7) rectification and capacitor (3) filtering binding post (6) _ with _ go up output.During (three) for butt welding, rivet welding, roll welding power supply, the output in parallel of secondary four tapped-windings, binding post (6) be numbered 1. 3. 5. 7. be connected to an output line with connecting plate (5).The binding post (6) that is numbered 2. 4. 6. 8. is connected to another root output line with connecting plate (5).(4) start cycling start or when filling storage battery, first tapped-winding of secondary winding (2) is connected with the 4th tapped-winding.Two diodes (7) full-wave rectification, electric capacity (3) filtering output.Promptly use connecting plate (5) to connect to be numbered 2. 7. _ binding post (6), _ _ binding post (6) goes up output.The electric current fine tuning of this electric welding machine is regulated at primary tap (figure 2 8) or controllable silicon (figure 1).
