Summary of the invention
Problem to be solved in the utility model is: there are many problems in existing ac spot welding machine, is mainly reflected in not prison welding, part oxidation, means of spot welds blackout, noise is large, has a strong impact on product quality.
The technical solution of the utility model is: ac spot welding machine, comprise power supply, floor push, the time relay, sinusoidal wave controller, silicon controlled module, transformer and welding head, power supply is to floor push and silicon controlled module power supply, floor push connects sinusoidal wave controller by the time relay, the output of sinusoidal wave controller connects silicon controlled module, the output connection transformer of silicon controlled module, the output connecting welding head of transformer.
The output of sinusoidal wave controller also connects sinusoidal wave working time indicator.
The utility model power supply is the AC power of 220V, and one the tunnel to silicon controlled module, and another road is to floor push.After floor push was stepped on conducting, the time relay got electric timing and exports the 6VDC pulse voltage to silicon controlled module by sinusoidal wave controller, and this rising edge of a pulse, trailing edge are 1ms, and rising edge conducting, trailing edge turn-off.The pulse output time is by sinusoidal wave working time indicator for displaying.
The utility model still adopts single-phase voltage regulator as the welding current size of transformer control inputs to welding head, adopts single-phase 3KW pressure regulator, can regulate arbitrarily according to the welding demand of part.The output of welding current adopts contactless semiconductor devices silicon controlled module to control, adopt the time relay contactless, the crystal oscillator working method weld interval, the adjusting time adopts the cycle control technology to control silicon controlled module by sinusoidal wave controller, and accuracy reaches 0.01 second.Sinusoidal wave controller least unit is half sine wave, sine wave of 20ms, but Set arbitrarily.Control circuit adopts time-delay disconnected, after circuit is connected, setting-up time is to automatically shutting down silicon controlled module, owing to being contactless conducting and cut-off, fully guarantee uniformity and the reliability of output current, avoided the speed of relay mechanical action to differ and the uncertainty of the conduction status that poor contact of contacts is brought.Floor push adopts the compressed spring type mode that automatically resets, when foot pressure during greater than spring pressure, and the floor push adhesive, pin pine automatic rebounding, the length of the time that can not step on because of individuality affect electric current and welds.Welding head adopts the nobelium pick copper of 8mm diameter, and this material has that fusing point is high, the strong characteristics of hardness.
To pick and have many problems, main manifestations be that not prison welding, part oxidation, means of spot welds blackout, noise are large to old AC spot-welding in the past, has a strong impact on product quality.The utility model can be eliminated the phenomenons such as not prison welding, part oxidation, means of spot welds blackout, has greatly improved product quality, is a technological break-through to aerobic open weld parts field, and its applicability is very strong, and the effect of getting instant result is arranged.
