Abstract
The utility model discloses a simple thermocouple welding instrument, which mainly comprises a charging circuit, a discharge circuit and a thermocouple.The charging circuit is a series loop composed of a transformer, a bridge rectifier, a charging capacitor and a resistor.The discharge circuit comprises a carbon rod and a nipper plier.The thermocouple is connected with the carbon rod and the nipper plier.One end of the capacitor is connected with the carbon rod and the other end thereof is connected with the nipper plier.According to the utility model, direct current pulse welding is adopted instead of alternating current welding and solder joints are both circle and brilliant. The success rate of welding is up to 100 %.Meanwhile, the loss of precious metals is reduced.The welding instrument has the advantages of small volume, convenient carrying and usage, safe and reliable operation and good quality.
Description
Technical field
The utility model relates to temperature TEMP, fields of measurement, especially a kind of instrument that is used for the welding of TEMP thermocouple.
Background technology
Thermocouple is widely used in TEMP, fields of measurement, and the thermocouple of diameter 0.1-0.5mm is very thin, is easy to during use damage; And materials such as thermocouple nickel commonly used, chromium, silicon, platinum, rhodium, the welding difficulty is big, the required precision height.General thermocouple welding can be with the soldering except T type thermocouple, and other all adopt spot welding or freeze.Existing welding instrument price is higher, volume is big, speed of welding is slow, loss is big, inefficiency, production cost are higher.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, provides that a kind of volume is little, easy to carry, easy to use, safe and reliable, speed of welding is fast, and quality is better, cost is low, effective thermocouple welding instrument.
The purpose of this utility model is finished by following technical solution, a kind of simple and easy thermocouple welding instrument, it mainly by:
One charging circuit includes transformer, bridge rectifier, charging capacitor and resistor and constitutes series loop;
One discharge circuit includes carbon-point and nipper plier and constitutes;
One thermocouple is connected on carbon-point and the nipper plier;
Described capacitor one end is connected to carbon-point, and the other end is connected on the nipper plier.
Described transformer is reduced to dc source below the 36V with voltage by the 220V AC power.
Thermocouple welding instrument of the present utility model, being mainly used in weld diameter is L type, K type, J type, the T type thermocouple of 0.1-0.5mm.Its maximum characteristics are that principle is simple, easy to operate, practicability and effectiveness, speed of welding are fast, making and use cost are low, are welded as the electric pulse welding because change general alternating current, and the solder joint garden is bright, be welded into power can reach 100%, has reduced the precious metal loss; And volume is little, portably use conveniently, safe and reliable, quality is better.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: as shown in Figure 1: a kind of simple and easy thermocouple welding instrument, it mainly by:
One charging circuit includes transformer 1, bridge rectifier 2, charging capacitor 3 and resistor 4 and constitutes series loop;
One discharge circuit includes carbon-point 4 and nipper plier 6;
One thermocouple 5 is connected on carbon-point 4 and the nipper plier 6;
Described capacitor 3 one ends are connected to carbon-point 4, and the other end is connected on the nipper plier 6.
Described transformer 1 is reduced to dc source below the 36V with voltage by the 220V AC power.
After isolating transformer 1 is reduced to safe voltage below the 36V, become direct current that capacitor 3 is charged by full-wave rectification again the AC power of 220V.One end of capacitor 3 is wired to carbon-point 4 other ends and is connected on the nipper plier 6.Two rhizoids of thermocouple 5 strand, three circle backs are clamped with nipper plier 6 expose about about 2mm, remove to bump thermocouple 5 with carbon-point 4, capacitor 3 discharge generation electric arcs weld thermocouple when carbon-point 4 and thermocouple 5 are collided.
