Abstract
The utility model provides a miniature spot welding machine which comprises a machine body. The utility model is characterized in that the circuit board of the machine body comprises a direct current power supply, a current-limiting resistor, an electrolytic capacitor assembly, a controlled silicon, a switch and an inductance coil. After the power supply is switched on, alternating current is used for charging the electrolytic capacitor assembly 6 through a transformer B and a bridge rectifier D. After charge is closed, the alternating current can automatically stop charging. When the miniature spot welding machine is used for spot welding, the switch K is switched on, the controlled silicon is switched on, and a spot welding contact point A has the output of current for achieving the goal of spot welding. The utility model has the advantage of small size.
Description
The utility model relates to the improvement of mash welder structure.
At present, industrial mash welder is to adopt high-power transformer and be furnished with bigger some welding stage, though can reach the purpose of spot welding, because volume is big, is not easy to move and uses.
The purpose of this utility model is exactly at the problems referred to above, and a kind of simple in structure, mash welder that volume is little is provided.
The purpose of this utility model is achieved in that the utility model comprises body, its structural feature is that the transformer of the dc source on the wiring board of body links to each other by the bridge rectifier of resistance with dc source, the resistance of leading up to of the positive terminal of bridge rectifier links to each other with the positive pole of storage battery, another road links to each other with the silicon controlled anode by inductance coil respectively, link to each other with the electrochemical capacitor group, one end of switch links to each other with the positive pole of bridge rectifier, and the other end is extremely continuous with silicon controlled control.
Major advantage of the present utility model:
1, volume is little:
The utility model mainly is to be provided with dc source, electrochemical capacitor group, controllable silicon, inductance coil, switch in body, therefore makes electricity capacity little, and assembly is also few, simple in structure, volume is little.
2, be widely used:
Because the utility model volume is little, and adopt the energy storage of electrochemical capacitor group, charging rate is fast, noiseless, and maximum input current is 5 amperes, therefore not only uses industrial, also can be used in the domestic power grid.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an electrical block diagram of the present utility model.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:
The utility model comprises body 3, and the transformer B of the dc source 7 on the wiring board 1 of body 3 passes through resistance R
1Link to each other with the bridge rectifier D of dc source 7, the positive terminal of bridge rectifier D lead up to resistance R
4Positive pole with storage battery links to each other, and another road links to each other with the anode of controllable silicon Q by inductance coil L respectively, links to each other with electrochemical capacitor group 6, and an end of K switch links to each other with the positive pole of bridge rectifier D, and the other end is extremely continuous with the control of controllable silicon Q.
Be provided with wiring board in the body 3, be respectively arranged with plug 4, power line 5, output 2 on the body 3.
Electrochemical capacitor group 6 comprises electrochemical capacitor C
1, C
2, C
3
Electrochemical capacitor group 6 is provided with corresponding K switch
1, K
2, be convenient to selection to output current.
For preventing that element is damaged, in this circuit, be provided with protective tube X

2
Behind the power connection, alternating current to 6 chargings of electrochemical capacitor group, stops charging by transformer B, bridge rectifier D automatically after being full of, at this moment, because K switch there is not conducting, so controllable silicon Q ends the output of spot welding contact A no current; During spot welding, the K switch conducting, just conducting thereupon of controllable silicon Q, the spot welding contact A has electric current output, can reach the purpose of spot welding.
The utility model can weld the iron plate of 0.2-2 millimeters thick, the corrosion resistant plate of 0.5-1.5 millimeters thick, the copper coin of 0.2-1 millimeters thick etc.
